B 1-1 1.0 Introduction The purpose of this air quality and greenhouse gas (GHG) impact study is to determine whether the estimated criteria air pollutants and greenhouse gas emissions generated from the proposed construction and operation of the 901 E. Katella Avenue In-Fill Residential Development Project (hereinafter referred to as “Project”) would cause a significant effect on the environment. This assessment was conducted within the context of the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000, et seq.). The methodology follows the California Air Resources Board (CARB), the South Coast Air Quality Management District (SCAQMD), and the City of Orange’s recommendations for the quantification and evaluation of air quality and GHG emissions. 1.1 Site Location The project site is located at 901 E. Katella Ave., on the northeast corner of the intersection at Cambridge Street and Katella Avenue, in the City of Orange, California. The project site is currently developed with an approximately 20,820 square foot vacant AT&T call center office building and a paved parking lot. The project site is located within the South Coast Air Basin (SCAB), the SCAQMD Inland Orange County General Forecast Area, and the Central Orange County Air Monitoring Area - 17. The project location map is provided in Exhibit A. 1.2 Project Description The proposed project consists of razing the existing vacant AT&T call center and constructing forty-nine (49) residential units with a density of 18.1 DU/AC. The site plan used for this analysis, provided by BASSENIAN LAGONI ARCHITECTS, is illustrated in Exhibit B. Table 1 summarizes the proposed project land uses. 1-2 Table 1 Land Use Summary Project Land Use CalEEMod Land Use Category Amount Metric Residential Condo/Townhouse 49 Dwelling Units Paved Surfaces Parking Lot 128 Spaces Construction of the project is expected to begin in the year 2023 and consist of demolition, site preparation, grading, building construction, paving, and architectural coating. The project is estimated to be open in the year 2024. The project is expected to require the total import of approximately 962 cubic yards of earthwork material during the grading phase. It should be noted that this study was conducted in November 2022 based on the proposed project including 52 residential dwelling units and 117 parking spaces. The project site plan has since been revised to include 49 dwelling units and 128 parking spaces. No significant changes or new sources of emissions have been added to the proposed project. Therefore, this report conservatively impacts based on the original site plan. 1.3 Sensitive Receptors Sensitive receptors are considered land uses or other types of population groups that are more sensitive to air pollution exposure. Sensitive population groups include children, the elderly, the acutely and chronically ill, and those with cardio-respiratory diseases. For CEQA purposes, the SCAQMD considers a sensitive receptor to be a location where a sensitive individual could remain for 24 hours or longer, such as residences, hospitals, and schools (etc), as described in the Localized Significance Threshold Methodology (SCAQMD 2008a, page 3-2). Several sensitive land uses are present surrounding the project site including the following: • Existing adjacent residential land uses directly north of the project site. • Existing adjacent residential land use to the northwest of the project site, approximately 125 feet from the centerline of N. Cambridge Street. 1-3 1.4 Summary of Air Quality and GHG Impacts Table 2 provides a summary of the CEQA air quality impact analysis results.

DF-11 Participate in the local waste management recycling and composting programs. 2-1 2.0 Air Quality Setting The Federal Clean Air Act (42 U.S.C. § 7602) defines air pollution as any agent or combination of such agents, including any physical, chemical, biological, or radioactive substance which is emitted into or otherwise enters the ambient air. Household combustion devices, motor vehicles, industrial facilities, and forest fires are common sources of air pollution. Air pollution can cause disease, allergies, and even death. It affects soil, water, crops, vegetation, manmade materials, animals, wildlife, weather, visibility, and climate. It can also cause damage to and deterioration of property, present hazards to transportation, and negatively impact the economy. This section provides background information on criteria air pollutants, the applicable federal, state, and local regulations concerning air pollution, and the existing physical setting of the project within the context of local air quality. 2.1 Description of Air Pollutants1. The following section describes the air pollutants of concern related to the project. Criteria air pollutants are defined as those pollutants for which the federal and state governments have established air quality standards for outdoor or ambient concentrations to protect public health. The following descriptions of criteria air pollutants have been provided by the SCAQMD. • Carbon Monoxide (CO) is a colorless, odorless, toxic gas produced by incomplete combustion of carbon-containing fuels (e.g., gasoline, diesel fuel, and biomass). Sources include motor vehicle exhaust, industrial processes (metals processing and chemical manufacturing), residential wood burning, and natural sources. CO is somewhat soluble in water; therefore, rainfall and fog can suppress CO conditions. CO enters the body through the lungs, dissolves in the blood, and competes with oxygen, often replacing it in the blood, thus reducing the blood's ability to transport oxygen to vital organs in the body. The ambient air quality standard for carbon monoxide is intended to protect persons whose medical condition already compromises their circulatory system's ability to deliver oxygen. These medical conditions include certain heart ailments, chronic lung diseases, and anemia. Persons with these conditions have reduced exercise capacity even when exposed to relatively low levels of CO. Fetuses are at risk because their blood has an even greater affinity to bind with CO. Smokers are also at risk from ambient CO levels because smoking 1 SCAQMD. Guidance Document for Addressing Air Quality Issues in General Plans and Local Planning (May 6, 2005) 2-2 increases the background level of CO in their blood. The South Coast basin has recently achieved attainment status for carbon monoxide by both USEPA and CARB. • Nitrogen Dioxide (NO2) is a byproduct of fuel combustion. The principal form of nitrogen oxide produced by combustion is nitric oxide (NO), but NO reacts quickly to form NO2, creating the mixture of NO and NO2 commonly called NOx. NO2 acts as an acute irritant and, in equal concentrations, is more injurious than NO. At atmospheric concentrations, however, NO2 is only potentially irritating. There is some indication of a relationship between NO2 and chronic pulmonary fibrosis. Some increase in bronchitis in young children has also been observed at concentrations below 0.3 parts per million (ppm). NO2 absorbs blue light which results in a brownish red cast to the atmosphere and reduced visibility. Although NO2 concentrations have not exceeded national standards since 1991 and the state hourly standard since 1993, NOx emissions remain of concern because of their contribution to the formation of O3 and particulate matter. • Ozone (O3) is one of several substances called photochemical oxidants that are formed when volatile organic compounds (VOC) and NOx react in the presence of ultraviolet sunlight. O3 concentrations in the South Coast basin are typically among the highest in the nation, and the damaging effects of photochemical smog, which is a popular name for a number of oxidants in combination, are generally related to the concentrations of O3. Individuals exercising outdoors, children, and people with preexisting lung disease, such as asthma and chronic pulmonary lung disease, are considered to be the subgroups most susceptible to O3 effects. Short-term exposures (lasting for a few hours) to O3 at levels typically observed in southern California can result in breathing pattern changes, reduction of breathing capacity, increased susceptibility to infections, inflammation of the lung tissue, and some immunological changes. In recent years, a correlation between elevated ambient O3 levels and increases in daily hospital admission rates, as well as mortality, has also been reported. The South Coast Air Basin is designated by the USEPA as an extreme non- attainment area for ozone. Although O3 concentrations have declined substantially since the early 1990s, the South Coast basin continues to have peak O3 levels that exceed both state and federal standards. • Fine Particulate Matter (PM10) consists of extremely small, suspended particles or droplets 10 microns or smaller in diameter that can lodge in the lungs, contributing to respiratory problems. PM10 arises from such sources as re-entrained road dust, diesel soot, combustion products, tire and brake abrasion, construction operations, and fires. It is also formed in the atmosphere from NOx and SO2 reactions with ammonia. PM10 scatters light and significantly reduces visibility. Inhalable particulates 2-3 pose a serious health hazard, alone or in combination with other pollutants. More than half of the smallest particles inhaled will be deposited in the lungs and can cause permanent lung damage. Inhalable particulates can also have a damaging effect on health by interfering with the body’s mechanism for clearing the respiratory tract or by acting as a carrier of an absorbed toxic substance. The South Coast basin has recently achieved federal attainment status for PM10, but is non-attainment based on state requirements. • Ultra-Fine Particulate Matter (PM2.5) is defined as particulate matter with a diameter less than 2.5 microns and is a subset of PM10. PM2.5 consists mostly of products from the reaction of NOx and SO2 with ammonia, secondary organics, finer dust particles, and the combustion of fuels, including diesel soot. PM2.5 can cause exacerbation of symptoms in sensitive patients with respiratory or cardiovascular disease, declines in pulmonary function growth in children, and increased risk of premature death from heart or lung diseases in the elderly. Daily fluctuations in PM2.5 levels have been related to hospital admissions for acute respiratory conditions, school absences, and increased medication use in children and adults with asthma. The South Coast basin is designated as non-attainment for PM2.5 by both federal and state standards. • Sulfur dioxide (SO2) is a colorless, pungent gas formed primarily by the combustion of sulfur-containing fossil fuels. Health effects include acute respiratory symptoms and difficulty in breathing for children. Individuals with asthma may experience constriction of airways with exposure to SO2. Though SO2 concentrations have been reduced to levels well below state and federal standards, further reductions in SO2 emissions are needed because SO2 is a precursor to sulfate and PM10. The South Coast basin is considered a SO2 attainment area by USEPA and CARB. • Lead (Pb) is a toxic heavy metal that can be emitted into the air through some industrial processes, burning of leaded gasoline and past use of lead-based consumer products. Lead is a neurotoxin that accumulates in soft tissues and bones, damages the nervous system, and causes blood disorders. It is particularly problematic in children, in that permanent brain damage may result, even if blood levels are promptly normalized with treatment. Concentrations of lead once exceeded the state and federal air quality standards by a wide margin, but as a result of the removal of lead from motor vehicle gasoline, ambient air quality standards for lead have not been exceeded since 1982. Though special monitoring sites immediately downwind of lead sources recorded localized violations of the state standard in 1994, no violations have been recorded since. Consequently, the South Coast basin is designated as an attainment area for lead by both the USEPA and CARB. This report 2-4 does not analyze lead emissions from the project, as it is not expected to emit lead in any significant measurable quantity. • Volatile Organic Compounds (VOC), although not actually a criteria air pollutant, VOCs are regulated by the SCAQMD because they cause chemical reactions which contribute to the formation of ozone. VOCs are also transformed into organic aerosols in the atmosphere, contributing to higher PM10 and lower visibility levels. Sources of VOCs include combustion engines, and evaporative emissions associated with fuel, paints and solvents, asphalt paving, and the use of household consumer products such as aerosols. Although health-based standards have not been established for VOCs, health effects can occur from exposures to high concentrations of VOC. Some hydrocarbon components classified as VOC emissions are hazardous air pollutants. Benzene, for example, is a hydrocarbon component of VOC emissions that are known to be a human carcinogen. The term reactive organic gases (ROG) are often used interchangeably with VOC. • Toxic Air Contaminants (TACs) are defined as air pollutants which may cause or contribute to an increase in mortality or serious illness, or which may pose a hazard to human health, and for which there is no concentration that does not present some risk. This contrasts with the criteria pollutants, in that there is no threshold level for TAC exposure below which adverse health impacts are not expected to occur. The majority of the estimated health risk from TACs can be attributed to a relatively few compounds, the most common being diesel particulate matter (DPM) from diesel engine exhaust. In addition to DPM, benzene and 1,3-butadiene are also significant contributors to overall ambient public health risk in California. 2.2 Federal and State Ambient Air Quality Standards The Federal Clean Air Act, which was last amended in 1990, requires the EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants considered harmful to public health and the environment. The State of California has also established additional and more stringent California Ambient Air Quality Standards (CAAQS) in addition to the seven criteria pollutants designated by the federal government. AAQS are designed to protect the health and welfare of the populace with a reasonable margin of safety. The standards are divided into two categories, primary standards, and secondary standards. Primary standards are implemented to provide protection for the “sensitive” populations such as those with asthma, or the children and elderly. Secondary standards are to provide protection against visible pollution as well as damage to the surrounding environment, including animals, crops, and buildings. 2-5 Table 4 shows the Federal and State Ambient Air Quality Standards. Table 4 Federal and State Ambient Air Quality Standards (AAQS)1 Air Pollutant Averaging Time 2 Federal Standard (NAAQS)2 California Standard (CAAQS)2 Ozone 1 Hour -- 0.09 ppm 8 Hour 0.070 ppm 0.070 ppm Carbon Monoxide (CO) 1 Hour 35 ppm 20 ppm 8 Hour 9 ppm 9 ppm Nitrogen Dioxide (NO2) 1 Hour 0.100 ppm 0.18 ppm Annual 0.053 ppm 0.030 ppm Sulfur Dioxide (SO2) 1 Hour 0.075 ppm 0.25 ppm 3 Hour 0.5 ppm3 -- 24 Hour -- 0.04 ppm Particulate Matter (PM10) 24 Hour 150 μg/m³ 50 μg/m³ Mean -- 20 μg/m³ Particulate Matter (PM2.5) 24 Hour 35 μg/m³ -- Annual 12 μg/m³ 12 μg/m³ Lead 30-day -- 1.5 μg/m Quarter 1.5 μg/m -- 3-month average 0.15 μg/m -- Visibility reducing particles 8 Hour -- 0.23/km extinction coefficient.

Lead is not included because the project is not anticipated to emit lead. Visibility-reducing particles are not explicitly addressed in this analysis because particulate matter is addressed. The project is not expected to generate or be exposed to vinyl chloride because the proposed project uses do not utilize the chemical processes that create this pollutant and there are no such uses in the project vicinity. The proposed project is not expected to cause exposure to hydrogen sulfide (H2S) because it would not generate hydrogen sulfide in any substantial quantity. The most common sources of H2S emissions are oil and natural gas extraction and processing, and natural emissions from geothermal fields. It is also formed during the bacterial decomposition of human and animal wastes and is present in emissions from sewage treatment facilities and landfills. Industrial sources include petrochemical plants, coke oven plants, and kraft paper mills. Sources for H2S within a residential project may occur through on-site composting of organic matter, however, the quantities are typically insignificant and avoidable by following proper composting techniques. Thus, H2S is not quantified within the State’s emissions estimator model. 2.3 Attainment Status The Clean Air Act requires states to prepare a State Implementation Plan (SIP) to ensure air quality meets the NAAQS. The California Air Resources Board (CARB) provides designations of attainment for air basins where AAQS are either met or exceeded. If the AAQS are met, the area is designated as being in “attainment”, while if the air pollutant concentrations exceed the AAQS, then the area is designated as being “nonattainment”. If there is inadequate or inconclusive data to make a definitive attainment designation, the area is considered “unclassified.” National nonattainment areas are further designated as marginal, moderate, serious, severe, or extreme as a function of deviation from standards. Each standard has a different definition, or ‘form’ of what constitutes attainment, based on specific air quality statistics. For example, the Federal 8-hour CO standard is not to be exceeded more than once per year; therefore, an area is in attainment of the CO standard if no more than one 8-hour ambient air monitoring values exceed the threshold per year. In contrast, the federal annual PM2.5 standard is met if the three-year average of the annual average PM2.5 concentration is less than or equal to the standard. When a state submits a request to the EPA to re-designate a nonattainment area to attainment, the Clean Air Act (CAA) section 175A(a) requires that the state (or states, if the area is a multi-state area) submit a maintenance plan ensuring the area can maintain the air quality standard for which the area is to be re-designated for at least 10 years following the effective date of re-designation. 2-7 Table 5 lists the attainment status for the criteria pollutants in the South Coast Air Basin (SCAB). Table 5 South Coast Air Basin Attainment Status1 Pollutant State Status National Status Ozone Nonattainment Nonattainment (Extreme)2 Carbon monoxide Attainment Attainment (Maintenance) Nitrogen dioxide Attainment Attainment (Maintenance) PM10 Nonattainment Attainment (Maintenance) PM2.5 Nonattainment Nonattainment Lead Attainment Nonattainment (Partial)3 1 Source: California Air Resources Board. http://www.arb.ca.gov/desig/adm/adm.htm 2 8-Hour Ozone. 3 Partial Nonattainment designation – Los Angeles County portion of Basin only. 2.4 South Coast Air Quality Management District (SCAQMD) The agency responsible for air pollution control for the South Coast Air Basin (SCAB) is the South Coast Air Quality Management District (SCAQMD). SCAQMD is responsible for controlling emissions primarily from stationary sources. SCAQMD maintains air quality monitoring stations throughout the SCAB. SCAQMD, in coordination with the Southern California Association of Governments, is also responsible for developing, updating, and implementing the Air Quality Management Plan (AQMP) for the SCAB. An AQMP is a plan prepared and implemented by an air pollution district for a county or region designated as nonattainment of the federal and/or California ambient air quality standards. The latest version is the 2016 AQMP. The 2016 AQMP is a regional blueprint for achieving federal air quality standards and healthful air. While air quality has dramatically improved over the years, the SCAB still exceeds federal public health standards for both ozone and particulate matter (PM) and experiences some of the worst air pollution in the nation. The 2016 AQMP includes both stationary and mobile source strategies to ensure that rapidly approaching attainment deadlines are met, that public health is protected to the maximum extent feasible and that the region is not faced with burdensome sanctions if the Plan is not approved or if the NAAQS are not met on time. 2-8 According to the 2016 AQMP, the most significant air quality challenge in the SCAB is to reduce nitrogen oxide (NOx) emissions sufficiently to meet the upcoming ozone standard deadlines. Based on the inventory and modeling results, 522 tons per day (tpd) of total SCAB NOx 2012 emissions are projected to drop to 255 tpd and 214 tpd in the 8-hour ozone attainment years of 2023 and 2031, respectively, due to the continued implementation of already adopted regulatory actions (“baseline emissions”). The analysis suggests that total SCAB emissions of NOx must be reduced to approximately 141 tpd in 2023 and 96 tpd in 2031 to attain the 8-hour ozone standards. This represents an additional 45 percent reduction in NOx in 2023, and an additional 55 percent NOx reduction beyond 2031 levels.2 2.4.1 SCAQMD Rules and Regulations The SCAQMD establishes a program of rules and regulations to obtain attainment of the state and federal standards in conjunction with the AQMP. Several of the rules and regulations that may be applicable to this project include, but are not limited to, the following: • SCAQMD Rule 402 prohibits a person from discharging from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property. • SCAQMD Rule 403 governs emissions of fugitive dust during construction and operation activities. Compliance with this rule is achieved through application of standard Best Management Practices, such as application of water or chemical stabilizers to disturbed soils, covering haul vehicles, restricting vehicle speeds on unpaved roads to 15 miles per hour, sweeping loose dirt from paved site access roadways, cessation of construction activity when winds exceed 25 mph, and establishing a permanent ground cover on finished sites. • SCAQMD Rule 445 restricts wood burning devices from being installed into any new development and is intended to reduce the emissions of particulate matter for wood burning devices. 2 SCAQMD. Final 2016 Air Quality Management Plan. http://www.aqmd.gov/home/air-quality/clean-air- plans/air-quality-mgt-plan/final-2016-aqmp 2-9 • SCAQMD Rule 1113 governs the sale, use, and manufacturing of architectural coating and limits the VOC content in paints and paint solvents. This rule regulates the VOC content of paints available during construction. Therefore, all paints and solvents used during construction and operation of project must comply with Rule 1113. • SCAQMD Rule 1143 governs the manufacture, sale, and use of paint thinners and solvents used in thinning of coating materials, cleaning of coating application equipment, and other solvent cleaning operations by limiting their VOC content. This rule regulates the VOC content of solvents used during construction. Solvents used during the construction phase must comply with this rule. • SCAQMD Rule 1186 limits the presence of fugitive dust on paved and unpaved roads and sets certification protocols and requirements for street sweepers that are under contract to provide sweeping services to any federal, state, county, agency or special district such as water, air, sanitation, transit, or school district. 2.5 Local Climate and Meteorology The project is in the South Coast Air Basin (SCAB).

Averages derived from measurements recorded between 1989 and 2016, Anaheim, CA (040192). 2.6 Local Air Quality The air quality at any site is dependent on the regional air quality and local pollutant sources. Regional air quality is determined by the release of pollutants throughout the air basin. Estimates of the existing emissions in the Basin provided in the Final 2016 Air Quality Management Plan, prepared by SCAQMD, March 2017, indicate that collectively, mobile sources account for 60 percent of the VOC, 90 percent of the NOx emissions, 95 percent of the CO emissions and 34 percent of directly emitted PM2.5, with another 13 percent of PM2.5 from road dust. The SCAQMD has divided the SCAB into fourteen general forecasting areas and thirty-eight Source Receptor Areas (SRA) for monitoring and reporting local air quality. The SCAQMD provides daily reports of the current air quality conditions in each general forecast area and SRA. The monitoring areas provide a general representation of the local meteorological, terrain, and air quality conditions within the SCAB. Table 7 summarizes the published air quality monitoring for the most recent 3-year period available. These pollutant levels were used to comprise a “background” for the project location and existing local air quality. For criteria pollutants not monitored near the site, data from the nearest monitoring station with a comparable setting were used. 2-11 Table 7 Local Air Quality Air Pollutant Location Averaging Time Item 2018 2019 2020 Carbon Monoxide -- Central Orange County 1 Hour Max 1-Hour (ppm) 2.3 2.4 2.3 Exceeded State Standard (20 ppm)No No No Exceeded National Standard (35 ppm) No No No 8 Hour Max 8 Hour (ppm)1.9 1.3 1.7 Days > State Standard (9 ppm) No No No Days >National Standard (9 ppm) No No No Ozone -- Central Orange County 1 Hour Max 1-Hour (ppm) 0.112 0.096 0.142 Days > State Standard (0.09 ppm)1.0 1.0 6.0 8 Hour Max 8 Hour (ppm)0.071 0.082 0.097 Days > State Standard (0.070 ppm) 1 1 15 Days >National Standard (0.070 ppm) 1 1 15 Nitrogen Dioxide -- Central Orange County 1 Hour Max 1-Hour (ppm) 0.066 0.059 0.071 Exceeded State Standard (0.18 ppm)No No No Annual Annual Average (ppm)0.014 0.013 0.013 Exceeded State Standard (0.030 ppm) No No No Exceeded National Standard (0.053 ppm) No No No Sulfur Dioxide -- Central LA 1 Hour Max 1 Hour (ppm) 0.0179 0.0100 0.0038 Exceeded State Standard (0.25 ppm)No No No Exceeded National Standard (0.075 ppm) No No No Suspended Particles (PM10) -- Central Orange County 24 Hour Max 24-Hour (μg/m³) 129 127 120 Days > State Standard (50 μg/m³) 13 13 13 Days >National Standard (150 μg/m³)0 0 0 Annual Annual Average (μg/m³)27.20 21.90 23.90 Exceeded State Standard (20 μg/m³)Yes Yes Yes Fine Particulates (PM2.5) -- Central Orange County 24 Hour Max 24-Hour (μg/m³)54.10 36.10 41.40 Days >National Standard (35 μg/m³) 3 3 1 Annual Annual Average (μg/m³) 11.02 9.32 11.27 Exceeded State Standard (12 μg/m³) No No No Exceeded National Standard (15 μg/m³)No No No Source: https://www.aqmd.gov/home/air-quality/historical-air-quality-data/historical-data-by-year μg/m³ = micrograms per cubic meter ARB = California Air Resource Board EPA= Environmental Protection Agency ppm = part per million (- -) = Data not provided 3-1 3.0 Global Climate Change Setting Global climate change is the change in the average weather of the earth that is measured by such things as alterations in temperature, wind patterns, storms, and precipitation. Current data shows that the recent period of warming is occurring more rapidly than past geological events. The average global surface temperature has increased by approximately 1.4° Fahrenheit since the early 20th Century. 1.4° Fahrenheit may seem like a small change, but it's an unusual event in Earth's recent history, and as we are seeing, even small changes in temperature can cause enormous changes in the environment. The planet’s climate record, preserved in tree rings, ice cores, and coral reefs, shows that the global average temperature has been stable over long periods of time. For example, at the end of the last ice age, when the Northeast United States was covered by more than 3,000 feet of ice, average global temperatures were only 5° to 9° Fahrenheit cooler than today. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5° to 10° Fahrenheit over the next century. Therefore, significant changes to the environment are expected in the near future. The consequences of global climate change include more frequent and severe weather, worsening air pollution by increasing ground-level ozone, higher rates of plant and animal extinction, more acidic and oxygen-depleted oceans, the strain on food and water resources, and threats to densely populated coastal and low lying areas from sea level rise. The impacts of climate change are already visible in the Southwest United States. In California, the consequences of climate change include; • A rise in sea levels resulting in the displacement of coastal businesses and residencies • A reduction in the quality and supply of water from the Sierra snowpack • Increased risk of large wildfires • Exacerbation of air quality problems • Reductions in the quality and quantity of agricultural products • An increased temperature and extreme weather events • A decrease in the health and productivity of California’s forests 3-2 3.1 Greenhouse Gases GHGs comprise less than 0.1 percent of the total atmospheric composition, yet they play an essential role in influencing climate. Greenhouse gases include naturally occurring compounds such as carbon dioxide (CO2), methane (CH4), water vapor (H2O), and nitrous oxide (N2O), while others are synthetic. Man-made GHGs include chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF6). Different GHGs have different effects on the Earth's warming. GHGs differ from each other in their ability to absorb energy (their "radiative efficiency") and how long they stay in the atmosphere, also known as the "lifetime". The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of CO2. The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. The time period usually used for GWPs is 100 years. GWPs provide a common unit of measure, which allows analysts to add up emissions estimates of different gases and allows policymakers to compare emissions reduction opportunities across sectors and gases. Table 8 lists the 100-year GWP of GHGs from the Intergovernmental Panel on Climate Change (IPCC) fifth (AR5) and sixth assessment report (AR6). 3-3 Table 8 Global Warming Potential of Greenhouse Gases1, 2 Gas Name Formula Lifetime (years) GWP Carbon Dioxide CO2 1 Methane CH4 (Fossil Origin) 12 29.8 CH4 (Non-Fossil Origin) 27.2 Nitrous Oxide N2O 114 273 Sulphur Hexafluoride SF6 3200 23,500 Nitrogen Trifluoride NF3 740 16,100 Chlorofluorocarbon (CFC-11) CFC-11 52 8,321 Hexafluoroethane (PFC-116) C2F6 10,000 11,100 Octafluoropropane (PFC-218) C3F8 2,600 8,900 Octafluorocyclobutane (PFC-318) C4F8 3,200 9,540 Tetrafluoromethane (PFC-14) CF4 50,000 5,301 Hydrofluorocarbon 125 HFC-125 29 3,170 Hydrofluorocarbon 134a HFC-134a 14 1,526 Hydrofluorocarbon 143a HFC-143a 52 4,800 Hydrofluorocarbon 152a HFC-152a 1 138 Hydrofluorocarbon 227ea HFC-227ea 34 3,350 Hydrofluorocarbon 23 HFC-23 270 12,400 Hydrofluorocarbon 236fa HFC-236fa 240 8,060 Hydrofluorocarbon 245fa HFC-245fa 8 858 Hydrofluorocarbon 32 HFC-32 5 771 Hydrofluorocarbon 365mfc HFC-365mfc 9 804 Hydrofluorocarbon 43-10mee HFC-43-10mee 16 1,650 1 Source: IPCC Sixth Assessment Report (AR6), https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_Full_Report.pdf & https://www.ipcc.ch/site/assets/uploads/2018/02/WG1AR5_Chapter08_FINAL.pdf 2 GWPs are used to convert GHG emission values to "carbon dioxide equivalent" (CO2e) units 3-4 3.2 GHG Regulatory Setting – State of California The State of California has been a leader in climate change legislation and has passed numerous bills to reduce greenhouse gas emissions across all sectors of the economy. Some of the key climate legislation in the State include the following: • Assembly Bill (AB) 32, California Global Warming Solutions Act of 2006. AB 32 set the stage for the State’s transition to a sustainable, low-carbon future. AB 32 was the first program in the country to take a comprehensive, long-term approach to address climate change.3 • Senate Bill (SB) 375, Sustainable Communities & Climate Protection Act of 2008. SB 375 requires the Air Resources Board to develop regional greenhouse gas emission reduction targets for passenger vehicles GHG reduction targets for 2020 and 2035 for each region covered by the State's 18 metropolitan planning organizations.4 • Senate Bill (SB) 100, California Renewables Portfolio Standard Program. SB 100 established a landmark policy requiring renewable energy and zero-carbon resources to supply 100 percent of electric retail sales to end-use customers by 2045.5 3.3 GHG Emissions Inventory Table 9 shows the latest GHG emission inventories at the national, state, regional, and local levels.

CalEEMod is a statewide land use emissions computer model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify criteria air pollutants and GHG emissions. The model quantifies direct emissions from construction and operation activities (including vehicle use), as well as indirect emissions, such as GHG emissions from off-site energy generation, solid waste disposal, vegetation planting and/or removal, and water use. The model also identifies mitigation measures to reduce criteria pollutant and GHG emissions. The model was developed for the California Air Pollution Control Officers Association (CAPCOA) in collaboration with the California air districts. 4.1 Construction Assumptions Construction of the project is estimated to begin in the year 2023. Construction activities are expected to consist of demolition, site preparation, grading, building construction, paving, and architectural coating. The project is expected to be operational in the year 2024. The project site is currently occupied by a vacant AT&T call center, and demolition is expected to be required. The project is expected to import approximately 962 cubic yards of earthwork material for grading purposes. The CalEEMod default construction equipment list is based on survey data and the size of the site. The parameters used to estimate construction emissions, such as the worker and vendor trips and trip lengths, utilize the CalEEMod defaults. The construction equipment list is shown in Table 10. The project will be required to comply with several standard fugitive dust control measures, per SCAQMD Rule 403. The following key inputs are utilized in CalEEMod and are based upon data provided from SCAQMD6: 6 SCAQMD. Fugitive Dust Mitigation Measures. http://www.aqmd.gov/home/rules-compliance/ceqa/air- quality-analysis-handbook/mitigation-measures-and-control-efficiencies/fugitive-dust 4-2 • Soil stabilizers - 30% PM10 and PM2.5 reduction. • Replace ground cover - 15% PM10 and PM2.5 reduction. • Water exposed areas 2x per day. • Unpaved road moisture content – 25%. • Unpaved road vehicle speed – 15 mph.

This report identifies the following parameters in the project design or applicable mitigation measures in order to compare CalEEMod reported emissions against the localized significance threshold lookup tables: 1) The off-road equipment list (including the type of equipment, horsepower, and hours of operation) assumed for the day of construction activity with maximum emissions. 2) The maximum number of acres disturbed on the peak day. 3) Any emission control devices added onto off-road equipment. 4) Specific dust suppression techniques used on the day of construction activity with maximum emissions. 4.3 Operational Assumptions Operational emissions occur over the life of the project and are considered “long-term” sources of emissions. Operational emissions include both direct and indirect sources. This section briefly describes the operational sources of emissions analyzed for the project. 4.3.1 Mobile Source Emissions Mobile source emissions are the largest source of long-term air pollutants from the operation of the project. Mobile sources are direct sources of project emissions that are primarily attributed to tailpipe exhaust and road dust (tire, brake, clutch, and road surface wear) from motor vehicles traveling to and from the site. Estimates of mobile source emissions require information on four parameters: trip generation, trip length, vehicle/fleet mix, and emission factors (quantity of emission for each mile traveled or time spent idling by each vehicle). The Emission Factors (EMFAC) 2017 model is used to estimate the mobile source emissions embedded in the CalEEMod emissions model. No adjustments have been made to default emission factors. The trip generation rates for this project are based on the ITE Trip Generation Manual 11th Edition, 2021. The project’s total vehicle miles traveled estimated by CalEEMod is shown in Table 11. 4-4 Table 11 Operational Vehicle Miles Traveled Land Use Annual Vehicle Miles Traveled (VMT)1 Condo/Townhouse 1,318,220 1 Unmitigated VMT. The operational vehicle fleet mix has been adjusted to reflect vehicle types used for typical residential and commercial trips generated by the project. The Southern California Association of Governments (SCAG) regional travel demand model does not assign heavy- duty trucks, buses, or other large vehicles that would require passenger car equivalent (PCE) adjustments to residential home-based trips. The project does not consist of land uses that would typically require PCE adjustments to account for large trucks, such as warehousing. To be conservative, the Air Quality/GHG analysis has assumed that 2% of the total residential home-based trips will include trucks with a gross vehicle weight rating (GVWR) of 10,000 pounds or greater. This includes LHD2, MHD, HHD, OBUS, UBUS, and SBUS vehicles. The 2% mix is also consistent with the default Highway Capacity Manual (HCM) assumptions. The adjusted vehicle mix is proportioned according to the default CalEEMod vehicle mix. Table 12 summarizes the vehicle mix used for this project. 4-5 Table 12 Operational Vehicle Mix1 Vehicle Class Vehicle Mix (%) Light Duty Automobile (LDA) 55.28% Light Duty Truck (LDTI) 6.03% Light Duty Truck (LDT2) 18.81% Medium Duty Truck (MDV) 12.94% Light Heavy Truck (LHD1) 2.46% Light Heavy Truck (LHD2) 0.42% Medium Heavy Truck (MHD) 0.92% Heavy Heavy Truck (HHD) 0.31% Other Bus (OBUS) 0.04% Urban Bus (UBUS) 0.02% Motorcycle (MCY) 2.48% School Bus (SBUS) 0.05% Motor Home (MH) 0.24% Total 100.0% 1Adjusted fleet mix to include 2% total trucks over 10,000 lbs. GVWR. (LHD2, MHD, HHD, OBUS, UBUS, SBUS, MH) 4.3.2 Energy Source Emissions Energy usage includes both direct and indirect sources of emissions. Direct sources of emissions include on-site natural gas usage (non-hearth) for heating, while indirect emissions include electricity generated by offsite power plants. Natural gas use is measured in units of a thousand British Thermal Units (kBTU) per size metric for each land use subtype and electricity use is measured in kilowatt-hours (kWh) per size metric for each land use subtype. CalEEMod divides building electricity and natural gas use into uses that are subject to Title 24 standards and those that are not. Lighting electricity usage is also calculated as a separate category in CalEEMod. For electricity, Title 24 uses include the major building envelope systems covered by Part 6 (California Energy Code) of Title 24, such as space heating, space cooling, water heating, and ventilation. Non-Title 24 uses include all other end uses, such as appliances, electronics, and other miscellaneous plug-in uses. 4-6 For natural gas, uses are likewise categorized as Title 24 or Non-Title 24. Title 24 uses include building heating and hot water end uses. Non-Title 24 natural gas uses include cooking and appliances (including pool/spa heaters). The baseline values are based on the California Energy Commission (CEC) sponsored California Commercial End Use Survey (CEUS). Table 13 shows the total annual expected electricity and natural gas usage for the proposed project.

Per SCAQMD rule 445, no wood-burning devices are allowed in new developments; therefore, no wood hearths are included in this project. Consumer products are various solvents used in non-industrial applications which emit ROGs during their product use. These typically include cleaning supplies, kitchen aerosols, cosmetics, and toiletries. 4.3.4 Other Sources of Operational Emissions Water. Greenhouse gas emissions are generated from the upstream energy required to supply and treat the water used on the project site. Indirect emissions from water usage are counted as part of the project’s overall impact. The estimated water usage for the project is reported in Table 14. 4-7 Waste. CalEEMod calculates the indirect GHG emissions associated with waste that is disposed of at a landfill. The program uses annual waste disposal rates from the California Department of Resources Recycling and Recovery (CalRecycle) data for individual land uses. The program quantifies the GHG emissions associated with the decomposition of the waste which generates methane based on the total amount of degradable organic carbon. The estimated waste generation by the project is reported in Table 14.

By complying with the thresholds of significance, the project would be in compliance with the SCAQMD Air Quality Management Plan (AQMP) and the federal and state air quality standards. Table 15 lists the air quality significance thresholds for the six air pollutants analyzed in this report. Lead is not included as part of this analysis as the project is not expected to emit lead in any significant measurable quantity. Table 15 SCAQMD Air Quality Significance Thresholds Pollutant Construction (lbs/day) Operation (lbs/day) NOX 100 55 VOC 75 55 PM10 150 150 PM2.5 55 55 SOX 150 150 CO 550 550 1 Source : http://www.aqmd.gov/docs/default-source/ceqa/handbook/scaqmd-air-quality-significance- thresholds.pdf 5.2 Air Quality Localized Significance Thresholds Air quality emissions were analyzed using the SCAQMD’s Mass Rate Localized Significant Threshold (LST) Look-up Tables. Table 16 lists the Localized Significance Thresholds (LST) used to determine whether a project may generate significant adverse localized air quality impacts. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard. LSTs are developed based on the ambient concentrations of four applicable air pollutants for source receptor area (SRA) 17 – Central Orange County. 5-2 The nearest existing sensitive receptors are located along the northern property line of the site, less than 25 meters from potential areas of on-site construction and operational activity. Although receptors are located closer than 25 meters to the site, SCAQMD LST methodology states that projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters. The SCAQMD provides localized thresholds for 1-, 2-, and 5-acre sites. However, because the project’s daily disturbance area is estimated to be 1.9 acres, this analysis utilizes a linear progression to estimate LST thresholds for a 1.9-acre site. Table 16 SCAQMD Localized Significance Thresholds1 (LST) Pollutant Construction (lbs/day) Operation (lbs/day) NOX 107.3 107.3 CO 672.7 672.7 PM10 5.9 1.6 PM2.5 3.9 1.1 1 Source: SCAQMD Mass Rate Localized Significance Thresholds for a 1.9-acre site in SRA-17 at 25 meters 5.3 GHG Significance Thresholds 5.3.1 SCAQMD Recommended GHG Thresholds SCAQMD has developed recommended GHG thresholds of significance to assist local agencies with determining the impact of a project for CEQA. SCAQMD’s objective in providing the GHG guidelines is to establish a performance standard that will ultimately contribute to reducing GHG emissions below 1990 levels, and thus achieve the requirements of the California Global Warming Solutions Act (AB 32). SCAQMD first issued the Interim CEQA Greenhouse Gas (GHG) Significance Thresholds guidance document in October 2008 and has since held several stakeholder working group meetings where staff has presented updated recommendations. The latest recommended GHG thresholds are based on the GHG CEQA Significance Threshold Stakeholder Working Group #15, September 2010. The SCAQMD describes a five-tiered approach for determining GHG Significance Thresholds. 5-3 • Tier 1 - If a project is exempt from CEQA, project-level and cumulative GHG emissions are less than significant. • Tier 2 - If the project complies with a GHG emissions reduction plan or mitigation program that avoids or substantially reduces GHG emissions in the project’s geographic area (i.e., city or county), project-level and cumulative GHG emissions are less than significant. For projects that are not exempt or where no qualifying GHG reduction plans are directly applicable, SCAQMD requires an assessment based on the following tiers. • Tier 3 - Consists of screening values that are intended to capture 90 percent of the GHG emissions from projects. If a project’s emissions are under the screening thresholds, then the project is less than significant. SCAQMD has presented two options that lead agencies could choose for screening values. Option #1 sets the thresholds for residential projects to 3,500 MTCO2e/year, commercial projects to 1,400 MTCO2e/year), and mixed use to 3,000 MTCO2e/year. Option #2 sets a single numerical threshold for all non-industrial projects of 3,000 MTCO2e/year. The current staff recommendation is to use option #2, but allows lead agencies to choose option #1 if they prefer. Regardless of which option a lead agency chooses to follow, it is recommended that the same option is consistently used for all projects. Table 17 shows the screening levels described in option #2, which has been used previously in the City of Orange. Table 17 SCAQMD Tier 3 GHG Screening Values Land Use Screening Value Industrial Projects 10,000 MTCO2e/Yr Residential/Commercial Projects 3,000 MTCO2e/Yr 6-1 6.0 Air Quality Impact Analysis Consistent with CEQA and the State CEQA Guidelines, a significant impact related to air quality would occur if the proposed project is determined to: a) Conflict with or obstruct implementation of the applicable air quality plan. b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable Federal or State ambient air quality standard. c) Expose sensitive receptors to substantial pollutant concentrations. d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. 6.1 Short-Term Air Quality Impacts - Construction 6.1.1 Regional Daily Emissions - Construction Daily air quality emissions include both on-site and off-site emissions associated with the construction of the project. Regional daily emissions of criteria pollutants are compared to the SCAQMD thresholds of significance. As shown in Table 18, daily emissions of criteria pollutants are expected to be below the allowable thresholds of significance. CalEEMod unmitigated daily emissions outputs are provided in Appendix A. 6-2 Table 18 Daily Construction Emissions Maximum Daily Emissions (lbs/day)1 Activity VOC NOx CO SO2 PM10 PM2.5 Demolition 1.54 16.31 14.50 0.03 2.03 0.90 Site Preparation 1.33 14.30 10.03 0.03 1.24 0.59 Grading 1.39 16.45 9.66 0.03 3.71 1.98 Building Construction 1.88 14.13 15.91 0.03 1.25 0.76 Paving 1.07 8.13 12.14 0.02 0.56 0.41 Architectural Coating 33.61 1.24 2.10 0.00 0.17 0.09 Maximum1 33.61 16.45 15.91 0.03 3.71 1.98 SCAQMD Threshold 75 100 550 150 150 55 Exceeds Threshold (?) No No No No No No 1 Maximum daily emission during summer or winter; includes both on-site and off-site project emissions. The project must follow mandatory SCAQMD rules and requirements with regard to fugitive dust control, as described in Section 6.1.3. Compliance with the standard dust control measures is considered to be part of the conditions of approval for the project and is reflected in the emissions in Table 18. Table 18 shows that the project’s daily construction emissions will be below the applicable SCAQMD air quality standards and thresholds of significance. As a result, the project would not contribute substantially to an existing or projected air quality violation. Furthermore, by complying with the SCAQMD standards, the project would not contribute to a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable Federal or State ambient air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors). The project’s short-term construction impact on regional air resources is less than significant. 6.1.2 Localized Emissions - Construction Table 19 illustrates the construction-related localized emissions and compares the results to SCAQMD LST thresholds. As shown in Table 19, the emissions will be below the SCAQMD 6-3 thresholds of significance for localized construction emissions. The project must follow all standard SCAQMD rules and requirements with regard to fugitive dust control, as described in Section 6.1.3. The project’s short-term construction impact on localized air resources is less than significant.

SRA-17, Central Orange County, 2-acre site, receptor distance 25 meters. 6.1.3 Fugitive Dust - Construction The project is required to comply with regional rules that assist in reducing short-term air pollutant emissions associated with suspended particulate matter, also known as fugitive dust. Fugitive dust emissions are commonly associated with land clearing activities, cut- and-fill grading operations, and exposure of soils to the air and wind. SCAQMD Rule 403 requires that fugitive dust is controlled with best-available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. In addition, SCAQMD Rules 402 and 403 require the implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off-site. To ensure full compliance with the applicable dust control standards, the following project design features will be incorporated as conditions of approval: DF-1 The project must follow the standard SCAQMD rules and requirements with regards to fugitive dust control, which include, but are not limited to the following: 1. All active construction areas shall be watered two (2) times daily. 2. Speed on unpaved roads shall be reduced to less than 15 mph. 6-4 3. Any visible dirt deposition on any public roadway shall be swept or washed at the site access points within 30 minutes. 4. Any on-site stockpiles of debris, dirt or other dusty material shall be covered or watered twice daily. 5. All operations on any unpaved surface shall be suspended if winds exceed 15 mph. 6. Access points shall be washed or swept daily. 7. Construction sites shall be sandbagged for erosion control. 8. Apply nontoxic chemical soil stabilizers according to manufacturers’ specifications to all inactive construction areas (previously graded areas inactive for 10 days or more). 9. Cover all trucks hauling dirt, sand, soil, or other loose materials, and maintain at least 2 feet of freeboard space in accordance with the requirements of California Vehicle Code (CVC) section 23114. 10. Use gravel aprons and track out grates at all truck exits. 11. Replace the ground cover of disturbed areas as quickly as possible. By complying with the above construction design features, the project impact from fugitive dust emissions is less than significant. 6.1.4 Odors - Construction Heavy-duty equipment in the project area during construction will emit odors; however, the construction activity would cease to occur after construction is completed. The project is required to comply with Rule 402 during construction, which states that a person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property. No other sources of objectionable odors have been identified for the proposed Project. Therefore, the project impact from odor emissions is less than significant. 6.1.5 Asbestos - Construction Asbestos is a carcinogen and is categorized as a hazardous air pollutant by the Environmental Protection Agency (EPA). Asbestos fibers embedded within construction materials become a health hazard once they are disturbed and rendered airborne, such as 6-5 through physical contact during building renovation and demolition activities. Asbestos is regulated through the National Emissions Standards for Hazardous Air Pollutants (NESHAP) and SCAQMD is the local enforcement authority for asbestos. Asbestos also occurs naturally in serpentine and ultramafic rock. Based on the California Division of Mines and Geology General Location Guide for Ultramafic Rocks in California - Areas More Likely to Contain Naturally Occurring Asbestos, naturally occurring asbestos has not been shown to occur within the vicinity of the project site. Therefore, the potential risk for naturally occurring asbestos (NOA) during project construction is small. In the event asbestos is found on the site, the project will be required to comply with SCAQMD and NESHAP standards and protocols. SCAQMD Rule 1403 establishes the survey requirements, notification, and work practice requirements to prevent asbestos emissions during construction activities. By following the required asbestos abatement protocols, the project impact from asbestos would be less than significant. 6.1.6 Diesel Particulate Matter - Construction The project will generate diesel particulate matter (DPM) during construction from off-road diesel equipment and trucks. The California Office of Environmental Health Hazard Assessment (OEHHA) adopted the Guidance Manual for Preparation of Health Risk Assessments (HRA Guidelines) to provide procedures for use in the Air Toxics Hot Spots Program or for the permitting of existing, new, or modified stationary sources.7 The HRA Guidelines provide risk factors based on exposure to toxic substances over a 30- year life span. The proposed project’s construction activity is not expected to be a long- term (i.e., 30 years) source of toxic air contaminant emissions and short-term risk factors have not been developed. Due to the significantly reduced risk from short-term exposure, SCAQMD does not typically require the evaluation of long-term cancer risk or chronic health impacts for construction operations from a project such as the one being proposed. Hence, the impacts from short-term exposure to DMP during project construction may be presumed to be less than significant without the need for a detailed HRA study. To help further reduce the potential health risks associated with DPM exposure during construction, the following project design features would be imposed as conditions of approval. Project design features include a recommendation for Tier 4 engines on all off- 7 OEHHA. Air Toxics Hot Spots Program. Risk Assessment Guidelines. Guidance for Preparation of Health Risk Assessments. February 2015. 6-6 road diesel equipment. Tier 4 engines, along with the latest national fuel standards, have been shown to yield PM reductions of over 95% from the typical Tier 2 and Tier 3 engines.8 Thus ensuring the potential DPM exposure to adjacent sensitive receptors is reduced to the maximum extent feasible. DF-2 All diesel construction equipment should have Tier 4 low emission “clean diesel” engines (OEM or retrofit) that include diesel oxidation catalysts and diesel particulate filters that meet the latest CARB best available control technology. DF-3 Construction equipment should be maintained in proper tune. DF-4 All construction vehicles should be prohibited from excessive idling. Excessive idling is defined as five (5) minutes or longer. DF-5 Minimize the simultaneous operation of multiple construction equipment units, to the maximum extent feasible. DF-6 The use of heavy construction equipment and earthmoving activity should be suspended during Air Alerts when the Air Quality Index reaches the “Unhealthy” level. DF-7 Establish an electricity supply to the construction site and use electric- powered equipment instead of diesel-powered equipment or generators, where feasible. DF-8 Establish staging areas for the construction equipment that are as far from adjacent residential homes, as feasible. DF-9 Use haul trucks with on-road engines instead of off-road engines for on-site hauling. 8 EPA. Control of Emissions of Air Pollution from Nonroad Diesel Engines and Fuel; Final Rule. (40 CFR Parts 9, 69, et al.) 6-7 6.2 Long-Term Air Quality Impacts - Operation 6.2.1 Daily Emissions - Operation Long-term operational air pollutant impacts from the project are shown in Table 20. The project is not expected to exceed any of the allowable daily emissions thresholds for criteria pollutants at the regional level. CalEEMod daily emissions outputs are provided in Appendix A. The project’s daily operational emissions will be below the applicable SCAQMD air quality thresholds of significance and the project would not contribute substantially to an existing or projected air quality violation. Furthermore, by complying with the SCAQMD standards, the project would not contribute to a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable Federal or State ambient air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors). The project-related long-term air quality impacts are less than significant.

As shown in Table 21, the emissions will be below the SCAQMD thresholds of significance for localized operational emissions. The project will result in less than significant localized operational emissions impacts.

The proposed project does not contain land uses that would typically be associated with significant odor emissions. The project will be required to comply with standard building code requirements related to exhaust ventilation, as well as comply with SCAQMD Rule 402. Rule 402 requires that a person may not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health, or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property. Project-related odors are not expected to meet the criteria of being a nuisance. The project’s operation would result in less than significant odor impacts. 6-9 6.2.4 Toxic Air Contaminants - Operations The project consists of a residential land use and does not include major sources of toxic air contaminants (TAC) emissions that would result in significant exposure of sensitive receptors to substantial pollutant concentrations. Examples of land uses that are major sources of TACs include distribution centers with heavy truck traffic, rail yards, ports, refineries, chrome plating facilities, dry cleaners, and gasoline dispensing stations. The project does not call for any of these uses. The project impact is considered less than significant. 7-1 7.0 Greenhouse Gas Impact Analysis Consistent with CEQA Guidelines, a significant impact related to greenhouse gas would occur if the proposed project were determined to: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment. b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing emissions of greenhouse gases. 7.1 Greenhouse Gas Emissions - Construction Greenhouse gas emissions are estimated for on-site and off-site construction activity using CalEEMod. Table 22 shows the construction greenhouse gas emissions, including equipment and worker vehicle emissions for all phases of construction. Construction emissions are amortized over 30 years and added to the long-term operational emissions, pursuant to SCAQMD recommendations. Table 22 Construction Greenhouse Gas Emissions Activity Emissions (MTC02e)1 On-site Off-site Total Demolition 21.22 10.77 31.99 Site Preparation 3.26 0.10 3.36 Grading 5.48 3.15 8.63 Building Construction 229.55 68.24 297.79 Paving 7.82 0.62 8.44 Architectural Coating 1.28 0.42 1.70 Total 268.61 83.30 351.91 Amortized over 30 years2 8.95 2.78 11.73 1 MTCO2e = metric tons of carbon dioxide equivalents (includes carbon dioxide, methane, nitrous oxide, and/or hydrofluorocarbon). 2 The emissions are amortized over 30 years and added to the operational emissions, pursuant to SCAQMD recommendations. 7-2 Because impacts from construction activities occur over a relatively short-term period of time, they contribute a relatively small portion of the overall lifetime project GHG emissions, and GHG emissions reduction measures for construction equipment are relatively limited. Therefore, SCAQMD recommends that construction emissions be amortized over a 30-year project lifetime and added to the overall project operational emissions.9 In doing so, construction GHG emissions are included in the overall contribution of the project, as further discussed in the following section. 7.2 Greenhouse Gas Emissions - Operation Greenhouse gas emissions are estimated for on-site and off-site operational activity using CalEEMod. Greenhouse gas emissions from mobile sources, area sources, and energy sources are shown in Table 23. CalEEMod annual GHG output calculations are provided in Appendix B.

Interim CEQA GHG Significance Thresholds. Page 3-10. 2008 7-3 The project-related long-term GHG impacts are less than significant. 7.3 Project Consistency with Greenhouse Gas Reduction Plans The project will be required to comply with the mandatory requirements of the latest 2019 California Building Standards Code, including Title 24, Part 11, CALGreen, and Title 24, Part 6, Energy Code. The purpose of the building standards is to reduce negative impacts on the environment through improved planning and design, energy efficiency, water efficiency and conservation, and material and resource conservation. The California Building Standards were developed to help meet the requirements of the Global Warming Solutions Act (AB 32). By complying with the California Building Standards Code requirements the project would not conflict with an applicable plan, policy, or regulation for the purpose of reducing the emissions of greenhouse gases, and the impact is considered less than significant. The following project design features will be implemented to ensure the project is consistent with applicable GHG reduction standards. DF-10 The project will comply with the mandatory requirements of the California Building Standards Code, Title 24, Part 6 (Energy Code) and Part 11 (CALGreen), including, but not limited to: • Install low flow fixtures and toilets, water-efficient irrigation systems, drought tolerant/native landscaping, and reduce the amount of turf. • Provide the necessary infrastructure to support electric vehicle charging. • Provide solar installations (or other sources of on-site renewable energy) per the prescribed Energy Design Ratings. DF-11 Participate in the local waste management recycling and composting programs. As a result, the project would not conflict with an applicable plan, policy, or regulation for the purpose of reducing the emissions of greenhouse gases, and the impact is considered less than significant. 8-1 8.0 Energy Impact Analysis The purpose of this energy conservation analysis is to review the project’s energy implications and provide recommendations to reduce wasteful, inefficient, and unnecessary consumption of energy during construction and operation. This analysis has been prepared within the context of the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000, et seq.). CEQA Guidelines, Appendix F, Energy Conservation, describes the framework within which energy conservation should be analyzed. Conserving energy implies the wise and efficient use of energy through decreasing overall per capita energy consumption, decreasing reliance on fossil fuels (such as coal, natural gas and oil), and increasing reliance on renewable energy sources. Table 24 provides a summary of the project’s impact to Energy resources, per the impact criteria described in CEQA Guidelines, Appendix G. Table 24 CEQA Energy Impact Criteria Energy Impact Criteria Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact Would the project: a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? X b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? X 8.1 Energy Impact - A Would the project result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? The project will implement the mandatory requirements of California’s Building Energy Efficiency Standards (Title 24, Part 6) and Green Building Standards (CALGreen, Title 24, 8-2 Part 11) to reduce energy consumption. California’s building energy standards are some of the strictest in the nation and the project’s compliance with the Building Code will ensure that wasteful, inefficient or unnecessary consumption of energy is minimized. The California Building Code is designed to reduce the amount of energy needed to heat or cool a building, reduce energy usage for lighting and appliances and promote usage of energy from renewable sources. In particular, the project will provide solar installations (or other sources of on-site renewable energy) to satisfy the prescribed Energy Design Ratings from the Energy Code. Thus, the project will significantly reduce its reliance on fossil fuels for building energy. By providing renewable sources of energy, the project satisfies recent court rulings which indicate that when determining if a project would have a potentially significant impact to energy conservation, the analysis should discuss whether any renewable energy features could be incorporated into the project10. Therefore, the project is impact is considered less than significant. 8.2 Energy Impact - B Would the project conflict with or obstruct a state or local plan for renewable energy or energy efficiency? The project’s impact is considered less than significant as the project will purchase electricity through Southern California Edison which is subject to the requirements of California Senate Bill 100 (SB 100). SB 100 is the most stringent and current energy legislation in California; requiring that renewable energy resources and zero-carbon resources supply 100% of retail sales of electricity to California end-use customers and 100% of electricity procured to serve all state agencies by December 31, 2045.11 The project will also comply with the mandatory requirements of California’s Green Building and Building Energy Efficiency standards that promote renewable energy and energy efficiency. Hence, the project will not conflict with or obstruct a state or local plan for renewable energy or energy efficiency and the impact is considered less than significant. 10 League to Save Lake Tahoe Mountain Area Preservation Foundation, et al. v.

Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 Memorandum Date: November 14, 2022 To: Emilie Simard, Intracorp From: Brianna Bernard Subject: Biological Resource Assessment for 901 E. Katella Project in the City of Orange Intracorp (Applicant) requested Carlson Strategic Land Solutions (CSLS) prepare a Biological Resource Assessment memorandum and graphics documenting the finding of a field review for potential sensitive plants and wildlife for the 901 East Katella Project (Project) located in the City of Orange, California. In support of Project efforts CSLS biologist, Brianna Bernard, conducted an analysis of the biological resources onsite on October 18, 2022. This memorandum provides the results of the site visit. 1.0 Project Location and Description The Project site is an abandoned building and parking lot located on the north-east corner of Katella Avenue and Cambridge Street at 901 East Katella Avenue in the City of Orange (Figures 1 and 2). The approximately 2.7-acre Project site is surrounded by residential uses to the north, and commercial uses to the east, south across Katella Avenue, and west across N Cambridge Street. The Project proposes to construct residential homes and associated infrastructure. Access would be provided driveways on Cambridge Street and Katella Avenue.

CSLS reviewed and consulted literature and databases focused on Orange County, California, including the California Natural Diversity Database (CNDDB) and the U.S. Fish and Wildlife Service (USFWS) Critical Habitat database. The CNDDB is a California Department of Fish and Wildlife (CDFW) species account database that inventories status and locations of rare plants and wildlife in California. The CNDDB was used to identify any sensitive plant communities and special status plants and wildlife that have potential to occur within the Project site. The USFWS’s online service for information regarding Final Critical Habitat designation within California was reviewed to determine if the Study Area is within any species’ designated Critical Habitat. The USFWS regulatory mapping process for the designation of critical habitat is an imprecise, broad-based, mapping exercise of areas that may or may not include constituent elements of the critical habitat designation. Due to this approach in mapping, large areas are designated as critical habitat regardless of the existing habitat, and as a result may include developed areas, such as buildings, roads, hardscape, and other such facilities, as well as natural habitats. 2.1.1 Plant Community Mapping Plant communities were mapped in the field directly onto a 200-scale (1” = 200’) focusing on dominant plant species. Plant species were identified using plant field and taxonomical guides, such as The Jepson Manual: Vascular Plants of California, second edition (Baldwin et al. 2012). Vegetation communities were characterized utilizing vegetation alliances in accordance with The Manual of California Vegetation, Second Edition (MCVII) (Sawyer et al. 2009). Where necessary, deviations were made on best professional judgment when areas did not fit into a specific habitat description provided by MCVII. After completing the fieldwork, the plant community polygons were digitized using Geographic Information System (GIS) technology to calculate acreages. 2.2 City of Orange Tree Ordinance The City establishes regulations and standards for the preservation, pr otection, and selected removal of trees. Tree protection, removal, and replacement standards are outlined in the City of Orange’s Municipal Code (Chapter 12.32). Per the City’s Municipal Code the intent is to preserve the vast number of majestic trees and other 901 Katella Project Biological Assessment November 14, 2022 Page 6 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 mature trees. The primary purpose of Chapter 12.32 Tree Preservation is to regulate the removal and destruction of trees from undeveloped and public interest property as defined in Section 12.32.040 and 12.32.050 of the City’s Municipal Code. Tree, as defined in Section 12.32.020 means any live plant which has a single trunk measuring 10.5 inches in circumference, measured at a point 24 inches above the ground level. Undeveloped property is defined in Section 12.32.040 as any real property which has not been caused to progress to a more improved, advanced state of development. Public interest property is defined in Section 12.32.050 as any property, privately owned or otherwise, whether developed or undeveloped, which has, because of the presence of certain trees of historical value in such property, become property endowed with a public interest. 2.3 Orange County Natural Community Conservation Plan and Habitat Conservation Plan (NCCP/HCP) The Orange County Natural Community Conservation Plan and Habitat Conservation Plan (NCCP/HCP) was prepared in cooperation with CDFW and USFWS. The NCCP/HCP focus’ on creating a multiple-species, multiple-habitat subregional Reserve System and implementing a long-term adaptive management program that will protect coastal sage scrub and other habitats and species located within the CSS habitat mosaic, while providing for economic uses that will meet the social and economic needs of the people of the subregion. The primary goal of the NCCP/HCP is to protect and manage habitat supporting a broad range of plant and animal populations. To accomplish this goal, the NCCP/HCP creates a subregional habitat Reserve System and implements a coordinated program to manage biological resources within the habitat reserve. 2.4 Jurisdictional Waters The Project site was assessed for jurisdictional Waters of the United States (U.S.) and Waters of the State. To determine the presence of a wetland, three indicators are required: (1) hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology. The methodology published in the U.S. Army Corps of Engineers 1987 Wetland Delineation Manual and the Arid West Supplement sets the standards for meeting each of the three indicators, which normally require that 50 percent or more dominant plant species typical of a wetland, soils exhibiting characteristics of saturation, and hydrological indicators be present. 901 Katella Project Biological Assessment November 14, 2022 Page 7 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 Additionally, jurisdiction over non-wetland Waters of the U.S. is typically determined through the observation of an Ordinary High Water Mark (OHWM), which is defined as the “line on the shore established by the fluctuation of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelvin g, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.” Projects with impacts to Waters of the U.S. are regulated under Sections 401 and 404 of the Clean Water Act. Waters of the State are regulated by the California Department of Fish and Wildlife (CDFW) through Section 1600 et seq. of the California Fish and Game Code. The limits of Waters of the State are defined as the “body of water that flows at least periodically or intermittently through a bed or channel having banks and supports fish or other aquatic life. This includes watercourses having surface or subsurface flow that supports or has supported riparian vegetation." Therefore, the limits extend from the channel bed to the top of the bank, with the addition of the canopy of any riparian habitat associated with the watercourse. 3.0 Results 3.1 Biological Results CSLS Biologist conducted a general biological survey within the Project site and surrounding 300-foot buffer, collectively referred to as the Study Area, on October 18, 2022. The survey was performed between 10:00 a.m. and 11:05 a.m. The temperature was 82 F during the field survey, with clear skies. Any inaccessible or restricted areas were surveyed using binoculars. The vegetation, trees, jurisdictional waters, and wildlife observed were documented. Representative photographs of the Study Area are included in Attachment A. 3.1.1 Vegetation Communities The Project site is a developed lot with an abandoned building and associated parking lot. The site is composed entirely of developed community with scattered ornamental species in the parking lot and frontage of the building (Figure 4). A description of the vegetation community is found below. Developed The entire Project site is developed with a 20,000 square foot abandoned building, a covered storage area, a cell phone tower all located east of the main abandoned 901 Katella Project Biological Assessment November 14, 2022 Page 8 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 building, an asphalt-paved parking lot, associated landscaping and two gated entryways located on the southern and western portions of the property. At the time of the biological assessment, signs of homeless encampments were observed within the abandoned building. Vegetation within this community include variegated agave (Agave americana ‘Variegata’), glossy privet (Ligustrum lucidum), creeping juniper (Juniperus horizontalis) and the following trees, all which occur along the frontage road: Table 2. Tree Species Onsite Jacaranda mimosifolia Jacaranda Ulmus parvifolia Chinese Elm Ceiba speciosa Silk Floss Trees 3.1.2 Special Status Plant and Wildlife Species The Project site contains no special-status vegetation type listed by the CNDDB and CDFW. Due to the developed environment of the Project site, it does not contain any suitable habitat for special status plants or wildlife. Several sensitive wildlife species were reported in the vicinity of the Project site based on the CNDDB and within the quadrangle search. No special status wildlife was identified or observed within the Project site during the field survey (Figure 5). 3.1.3 Critical Habitat The Study Area is not located within any designated critical habitat. The closest mapped critical habitat occurs approximately 2.87 miles to the east for the coastal California gnatcatcher (Polioptila californica californica). The Project site does not contain any suitable habitat for these species. 3.1.4 Wildlife Species The Project site is located along a busy corridor along Katella Avenue and Cambridge Street. Due to this wildlife species observed onsite was low during the survey and consisted primarily of species accustomed to urban settings. Observed species include American crow (Corvus brachyrhynchos), black phoebe (Sayornis nigricans), Anna’s hummingbird (Calypte anna), song sparrow (Melospiza melodia), and mourning dove (Zenaida macroura). 3.2 NCCP/HCP The Project site is not located within the mapped boundary of the Orange County NCCP/HCP. 901 E.

During the field survey, the biologists paid special attention for any drainages meeting the regulatory definitions of waters. The Project site is a developed condition with an abandoned building and associated parking lot. Based on the field survey, there are no features identified on the Project site that meet the definition and are considered jurisdictional Waters of the United States or Waters of the State, pursuant to Section 1600-1603 of the California Fish and Game Code and Section 401 and 404 of the Clean Water Act, respectively. 4.0 Impacts With the implementation of the Project the entire parcel will be impacted. 4.1 Biological Results 4.1.1 Vegetation Communities Development of the Project site would result in the direct removal of non-native species and hardscape, including buildings and parking lot. No special status or sensitive plant species were identified to occur onsite, nor were they observed onsite. The Project site is developed with some ornamental species. The Project would include the removal of non-native ornamental species, which are abundant in the area; therefore, impacts would not be considered a significant impact and no mitigation is required. 4.1.2 Sensitive Wildlife Species Development of the Project site would result in the disruption and removal of potential nesting habitat in the form of buildings, ornamental trees, and shrubs. Due to the built nature of the site, the busy intersection, and development within the vicinity (e.g., nearby commercial buildings), these impacts would not be expected to reduce the general wildlife populations below self-sustaining levels within the region and impacts to non-sensitive wildlife species do not meet the significance thresholds. Therefore, impacts to common wildlife species would not be considered a significant impact and no mitigation is required. The Project site consists of developed habitat and lacks suitable habitat for sensitive wildlife species. The Project site provides limited suitable habitat for some common avian species in the form of ornamental species and existing building eaves. While none of the common species carry a Federal or State listing as threatened or endanger ed, they are all protected under the Migratory Bird Treaty Act (MBTA). Therefore, a pre- construction survey is required in compliance with the MBTA. Implementation of 901 Katella Project Biological Assessment November 14, 2022 Page 12 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 Mitigation Measure MM BIO-1 would reduce potential impacts to the avian species to a less than significant level, if nesting individuals are present. MM BIO-1 Prior to the issuance of any grading permit that would impact potentially suitable nesting habitat for avian species, the project applicant shall adhere to the following: 1. Vegetation removal activities shall be scheduled outside the nesting season (September 1 to February 14 for songbirds; September 1 to January 14 for raptors) to the extent feasible to avoid potential impacts to nesting birds and/or ground nesters. 2. Any construction activities that occur during typical nesting season (February 15 to August 31 for songbirds; January 15 to August 31 for raptors) will require that all suitable habitat, on-site and within 300-feet surrounding the site (as feasible), be thoroughly surveyed for the presence of nesting birds by a qualified biologist before commencement ground disturbances. If active nests are identified, the biologist would establish buffers around the vegetation (500 feet for raptors and sensitive species, 200 feet for non-raptors/non-sensitive species). All work within these buffers would be halted until the nesting effort is finished (i.e. the juveniles are surviving independent from the nest). The onsite biologist would review and verify compliance with these nesting boundaries and would verify the nesting effort has finished. Work can resume within these areas when no other active nests are found. Alternatively, a qualified biologist may determine that construction can be permitted within the buffer areas and wou ld develop a monitoring plan to prevent any impacts while the nest continues to be active (eggs, chicks, etc.). Upon completion of the survey and any follow-up construction avoidance management, a report shall be prepared and submitted to City for mitigation monitoring compliance record keeping. 4.1.3 Wildlife Corridor The Project site is surrounded by commercial building and residential development and does not function as a wildlife corridor. Furthermore, the Project site is a gated parcel and is located on the corner of a busy inte rsection with consistent traffic and noise further deterring the use of the site as corridor. As such, no impacts would occur, and no mitigation is required. 901 Katella Project Biological Assessment November 14, 2022 Page 13 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 4.2 Local Ordinances or Policies While the City has a tree ordinance, the intent and purpose of the ordinance is to regulate the removal and destruction of trees from undeveloped and public interest property. The Project site is a developed parcel and does not meet the definition of public interest property. However, as part of Project construction and design, ornamental landscaping will be incorporated into the residential neighborhood in the form of trees and shrubs. While the trees found onsite do not meet the definition of the City’s tree ordinance and therefore do not require mitigation, the Project design incorporate trees, shrubs, and other ornamental ground cover . Therefore, no impacts would occur, and no mitigation is required. 4.3 Adopted Habitat Conservation Plan The Project site is not mapped within the boundary of the Orange County NCCP/HCP. Therefore, no impacts would occur, and no mitigation is required. 4.4 Jurisdictional Features No jurisdictional features occur on the Project site that meet the definition and are considered jurisdictional Waters of the United States or Waters of the State, pursuant to Section 1600-1603 of the California Fish and Game Code and Section 401 and 404 of the Clean Water Act, respectively. Therefore, no impacts would occur, and no mitigation is required. 5.0 Summary The Project site consists of an abandon building on a developed lot with scattered ornamental trees and shrubs. The Project site does not contain sensitive habitat or suitable habitat for sensitive species. While the site is developed, the building and scattered ornamental species could provide suitable nesting habitat for avian species. Due to the suitable habitat, direct impacts could occur to nesting birds should construction activities and ground disturbances begin during the typical nesting season. However, adherence and implementation of MM BIO - 1 will ensure impacts to avian species or their habitats are minimized thus reducing the Project’s impact to less than significant. The Project site does not fall within the Orange County NCCP/HCP boundary. While the City does have an ordinance for trees, the Project does not meet the purpose or intent of the ordinance. However, the Project does propose landscaping as part of the final design. 901 Katella Project Biological Assessment November 14, 2022 Page 14 of 14 Carlson Strategic Land Solutions | 27134A Paseo Espada, Suite 323, San Juan Capistrano, California 92675 No jurisdictional features are present onsite.

–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– iv MANAGEMENT SUMMARY/ABSTRACT In response to a request from the project applicant, BFSA Environmental Services, a Perennial Company (BFSA) conducted a cultural resources study for the proposed 901 East Katella Avenue Project (Assessor’s Parcel Number [APN] 375-461-41). The 2.71-acre project is located northeast of the intersection of North Cambridge Street and East Katella Avenue, at 901 East Katella Avenue in the city of Orange, Orange County, California. The project is situated within the former unsectioned Santiago de Santa Ana Land Grant (Township 4 South, Range 9 West [projected]) as found on the USGS Orange, California topographic quadrangle. The project proposes the demolition of the existing commercial/office building on the property and the construction of a new residential community. The purpose of this investigation was to locate and record any cultural resources present within the project and subsequently evaluate any resources as part of the City of Orange’s environmental review process conducted in compliance with the California Environmental Quality Act (CEQA). The archaeological investigation of the project also included a review of an archaeological records search performed at the South Central Coastal Information Center (SCCIC) at California State University, Fullerton (CSU Fullerton) in order to assess previous archaeological studies and identify any previously recorded archaeological sites within the project or in the immediate vicinity. A Sacred Lands File (SLF) search was also requested from the Native American Heritage Commission (NAHC). Survey conditions were generally fair; however, the ground surface was not visible throughout the majority of the survey area. The existing commercial/office building and asphalt parking lots covered the subject property with only a few planters and landscaped areas providing a view of the exposed ground. According to aerial photographs, the current development within the project is older than 50 years. The building was constructed between 1970 and 1972, and was first used by the Pacific Telephone Company of Santa Ana and later by AT&T after SBC acquired Pacific Bell Telephone Company. Based on a review of the building it is clear the structure design of the building was influenced by International-style architecture. However, an analysis and evaluation of the structure provided in Section 3.0 shows that the building is not a good example, does not possess a high level of integrity, and is not considered a “Historical Resource” under CEQA critera. Therefore, no significant or CRHR eligible resources exist within the project. As such, no potential impacts to significant cultural resources are associated with the proposed development of the project. The 901 East Katella Project will not result in direct impacts to any significant cultural resources. Due to the disturbed nature of the property as a result of previous agricultural use, clearing, grading, and the 1970s development within the subject property, there is little likelihood that archaeological deposits are present within the project boundaries. Therefore, it is recommended that the project be allowed to proceed without mitigation measures. A copy of this report will be permanently filed with the SCCIC at CSU Fullerton. All notes, photographs, and other materials related to this project will be curated at the archaeological laboratory of BFSA in Poway, California. Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–1 1.0 INTRODUCTION 1.1 Project Description The archaeological survey program for the 901 East Katella Avenue Project was conducted in order to comply with CEQA and City of Orange environmental guidelines. The 2.71-acre project (APN 375-461-41) is located northeast of the intersection of North Cambridge Street and East Katella Avenue, at 901 East Katella Avenue in the city of Orange, Orange County, California (Figure 1.1–1). The project is situated within the former unsectioned Santiago de Santa Ana Land Grant (Township 4 South, Range 9 West [projected]) as found on the USGS Orange, California topographic quadrangle (Figure 1.1–2). The project proposes the demolition of the existing commercial/office building on the property and the construction of a new residential community (Figure 1.1–3). The decision to request this investigation was based upon cultural resource sensitivity of the locality as suggested by known site density and predictive modeling. Sensitivity for cultural resources in a given area is usually indicated by known settlement patterns, which in Orange County were focused around freshwater resources and a food supply. 1.2 Environmental Setting The 901 East Katella Avenue Project is generally situated in the Peninsular Ranges Geologic Province of southern California. The range, which lies in a northwest-to-southeast trend through the county, extends some 1,000 miles from the Raymond-Malibu Fault Zone in western Los Angeles County to the southern tip of Baja California. The current path of the Santa Ana River lies approximately one-and-a-half miles west of the project. Geologically, the surficial sediments across the project are mapped as late to middle Pleistocene-aged old alluvial fan deposits, mostly consisting of unconsolidated, alluvial silty sands (Morton and Miller 2006). These deposits represent the erosional detritus transported and deposited by Santiago Creek, east of the project, during the wetter climatic conditions of the Pleistocene. The specific soil type mapped within the project is characterized as Myford sandy loam, 0 to 2 percent slopes. At the present the property is developed, containing a commercial/office building and associated paved parking lot formally utilized by the local telephone utility. Vegetation within the project is minimal consisting of maintained commercial landscaping. Historically the property was utilized for agriculture and contained a citrus grove. The vegetation during prehistoric times most likely consisted of a river valley riparian environment within the Santa Ana River watershed, native oak trees, and coastal/inland sage/scrub and chaparral in the nearby foothills. Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–5 1.3 Cultural Setting 1.3.1 Prehistoric Period Archaeological investigations in southern California have documented a diverse and rich record of human occupation spanning the past 10,000 years. In northern San Diego, Orange, and Riverside counties, most researchers organize prehistory into the Paleo Indian, Archaic, and Late Prehistoric Periods, and history into the Mission, Rancho, and American Settlement periods. The San Dieguito Complex, Milling Stone Horizon, La Jolla Complex, Pauma Complex, and San Luis Rey Complex are the archaeological manifestations that have been used to describe the Archaic and Late Prehistoric periods in the region. Paleo Indian Period (Late Pleistocene: 11,500 to circa 9,000 YBP) The San Dieguito Complex/Paleo Indian Period is associated with the terminus of the late Pleistocene (11,500 to 9,000 years before the present [YBP]). The term “San Dieguito Complex” is a cultural distinction used to describe a group of people that occupied sites in the region between 11,500 and 7,000 YBP. Initially believed to have been big game hunters, the San Dieguito are better typified as wide-ranging hunter/gatherers. The earliest evidence of San Dieguito Complex sites is known from San Diego County, the Colorado Desert, and further north along the California coast. These people abandoned the drying inland lakes of the present California desert and arrived in San Diego County circa 9,000 YBP, as documented at the Harris (SDI-149; Warren 1966), Rancho Park North (SDI-4392; Kaldenberg 1982), and Agua Hedionda (SDI-210/UCLJ-M-15 and SDI-10,965/SDM-W-131 [Moriarty 1967; Gallegos and Carrico 1984; Gallegos 1991]) sites. A San Dieguito component appears to have been present in the lower strata, “Malaga Cove I,” at the Malaga Cove Site (LAN-138) in the city of Palos Verdes Estates in Los Angeles County (Walker 1951). Other Paleo Indian Period sites containing San Dieguito components in the coastal region of southern California have been identified at the Irvine (ORA-64 [Drover et al. 1983; Macko 1998]), Ballona Creek, Angeles Mesa, and Rancho La Brea (Wallace 1955: 215–218) sites. Diagnostic San Dieguito artifacts include finely crafted scraper planes, choppers, scrapers, crescentics, elongated bifacial knives, and intricate leaf-shaped points (Rogers 1939; Warren 1967). This tool assemblage resembles those of the Western Lithic Co-Tradition (Davis et al. 1969) and the Western Pluvial Lakes Tradition (Bedwell 1970; Moratto 1984). Typical San Dieguito sites lack ground stone tools. The San Dieguito Complex is the least understood of the cultures that occupied the southern California region and debate continues as to whether the San Dieguito sites are actually different activity areas of the early Encinitas Tradition peoples (Bull 1987; Gallegos 1987), or whether the San Dieguito Complex peoples had a separate origin and culture from the Encinitas Tradition (Hayden 1987; Moriarty 1987; Smith 1987). According to this second scenario, the San Dieguito Complex peoples may have been assimilated into the dominant Encinitas Tradition culture (Kaldenberg 1982; Moriarty 1967). A third possibility is that the San Dieguito Complex gave rise to the Encinitas Tradition (Koerper et al. 1991). Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–6 Archaic Period (Early and Middle Holocene: circa 9,000 to 1,300 YBP) The Archaic Period begins with the onset of the Holocene around 9,000 YBP. The transition from the Pleistocene to the Holocene was a period of major environmental change throughout North America (Antevs 1953; Van Devender and Spaulding 1979). In southern California, the general climate at the beginning of the early Holocene was marked by cool/moist periods and an increase in warm/dry periods and rising sea levels. The warming trend and rising sea levels generally continued until the late Holocene. Archaeological research indicates that southern California was occupied between 9,000 and 1,300 YBP by a population(s) that utilized a wide range of both marine and terrestrial resources. A number of different archaeological manifestations based upon geographical setting, tool kit, and/or chronology are recognized during the Archaic Period, including the Milling Stone Horizon and San Dieguito, La Jolla, Encinitas, and Pauma complexes. Archaic sites generally contain milling tools, especially manos and metates, cobble and flake tools, dart projectile points and the concomitant use of the atlatl, crescents, shell, fish bone, and animal bone representing large and small game. Additionally, Archaic groups buried their dead as flex inhumations, a religious and cultural practice that is distinct from the succeeding Late Prehistoric groups. The La Jolla Complex is regionally associated with the Encinitas Tradition (Warren 1968) and shared cultural components with the widespread Milling Stone Horizon (Wallace 1955). The coastal expression of this complex, which focused upon coastal resources and development of deeply stratified shell middens located primarily around bays and lagoons, appeared in the southern California coastal areas. Some of the older sites associated with this expression are located at Topanga Canyon, Newport Bay, Agua Hedionda Lagoon, and some of the Channel Islands. Radiocarbon dates from sites attributed to this complex span a period of more than 7,000 years in this region, beginning more than 9,000 YBP. The Encinitas Tradition is best recognized for its pattern of large coastal sites characterized by shell middens, grinding tools closely associated with the marine resources of the area, cobble- based tools, and flexed human burials (Shumway et al. 1961; Smith and Moriarty 1985). While ground stone tools and scrapers are the most recognized tool types, coastal Encinitas Tradition sites also contain numerous utilized flakes, which may have been used to pry open shellfish. Artifact assemblages at coastal sites indicate a subsistence pattern focused upon shellfish collection and nearshore fishing, which suggests an incipient maritime adaptation with regional similarities to more northern sites of the same period (Koerper et al. 1986). Other artifacts associated with Encinitas Tradition sites include stone bowls, doughnut stones, discoidals, stone balls, and stone, bone, and shell beads. By 5,000 YBP, an inland expression of the La Jolla Complex, which exhibits influences from the Campbell Tradition from the north, is evident in the archaeological record. These inland Milling Stone Horizon sites have been termed “Pauma Complex” (True 1958; Warren et al. 1961; Meighan 1954). By definition, Pauma Complex sites share a predominance of grinding implements (manos and metates), lack mollusk remains, have a greater tool variety (including Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–7 atlatl dart points, quarry-based tools, and crescentics), and seem to express a more sedentary lifestyle with a subsistence economy based upon the use of a broad variety of terrestrial resources. Although originally viewed as a separate culture from the coastal La Jolla Complex (True 1980), it appears that these inland sites may be part of a subsistence and settlement system utilized by the coastal peoples. Late Prehistoric Period (Late Holocene: 1,300 YBP to 1790) The Late Prehistoric Period, sometimes referred to as San Luis Rey I and II, began approximately 1,300 YBP. Cremation, ceramics, the bow and arrow, small triangular points, the use of Obsidian Butte obsidian, and the reliance upon the acorn as a main food staple are the defining characteristics of the Late Prehistoric Period (Chartkoff and Chartkoff 1984; Gallegos 2002, Moratto 1984). These characteristics are thought to represent the movement of Shoshonean- speaking groups into northern San Diego, Orange, Riverside, and Los Angeles counties. Economic systems diversified and intensified during this period with the continued elaboration of trade networks, cremation of the dead, the use of shell-bead currency, and the appearance of more labor- intensive, yet effective, milling technologies such as the bedrock mortar for use in acorn processing. Protohistoric Period (Late Holocene: 1790 to Present) This period begins with the Hispanic intrusion into southern California and the founding of the Mission San Juan Capistrano near what is currently the Lake Forest area in 1776. Ethnohistorical and ethnographic evidence indicates that three Shoshonean-speaking groups that occupied the southern and eastern portions of Orange County were the Luiseño, Gabrielino, and Acjachemem (Juaneño), each of which is culturally similar but that possess slight dialectic differences. Along the coast, the groups made use of the available marine resources by fishing and collecting mollusks for food. Seasonally available terrestrial resources, including acorns and game, were also sources of nourishment for these groups. The elaborate kinship and clan systems between these groups facilitated a wide-reaching trade network that included trade of Obsidian Butte obsidian, resources from the eastern deserts, and steatite from the Channel Islands. All three groups also shared a distinct world view that stemmed from use of the hallucinogen datura and an elaborate religion that included ritualized sand paintings of the sacred being Chingichngish (Bean and Shipek 1978; Kroeber 1976). Some notable differences, however, can be seen in the material culture between the three groups. For example, the Gabrielino used containers made from steatite, which is a soapstone material from the Santa Catalina Islands, instead of pottery, which was the preferred material for the Juaneño and the Luiseño (Kroeber 1976). The Luiseño, Gabrielino, and Juaneño occupied sedentary villages most often located in sheltered areas in valley bottoms, along streams, or along coastal strands near mountain ranges. Villages were located near water sources to facilitate acorn leaching and in areas that offered thermal and defensive protection. Villages were composed of areas that were both publicly and Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–8 privately, or family, owned. Publicly owned areas included trails, temporary campsites, hunting areas, and quarry sites. Inland groups had fishing and gathering sites along the coast that were utilized, particularly from January to March, when inland food resources were scarce. During October and November, most of the village would relocate to mountain oak groves to harvest acorns. For the remainder of the year, most would remain at the village sites, where food resources were within a day’s travel (Bean and Shipek 1978; Kroeber 1976). The Aliso Creek watershed has been reported to be the ethnohistoric boundary between the Luiseño, Gabrielino, and Juaneño. The Gabrielino occupied territory northwest of Aliso Creek, the Juaneño occupied territory to the south, and the Luiseño occupied territory to the southeast and east. However, there is evidence indicating that the Juaneño territory actually extended farther north, possibly past the Santa Ana River into modern-day Huntington Beach (Boscana 1978 [1933]). 1.3.2 Historic Period The historic period began on July 16, 1769, when the first Spanish exploring party commanded by Gaspar de Portolá (with Father Junípero Serra in charge of religious conversion of the native populations) arrived in San Diego to secure California for the Spanish (Palou 1926). The natural attraction of the harbor at San Diego and the establishment of a military presence in the area solidified the importance of San Diego to the Spanish colonization of the region and the growth of the civilian population. Missions were constructed from San Diego to as far north as San Francisco. The mission locations were based upon a number of important territorial, military, and religious considerations. Grants of land were made to those who applied, but many tracts reverted back to the government due to lack of use. As an extension of territorial control by the Spanish, each mission was placed so as to command as much territory and as large a population as possible. Mission San Juan Capistrano, located near the present Lake Forest area, exerted much influence over the Acjachemem (Juaneño), who either adapted to mission life, rebelled and ran away, or died from European diseases. While primary access to California during the Spanish Period was by sea, the route of El Camino Real served as the land route for transportation, commercial, and military activities. This route was considered to be the most direct path between the missions (Rolle 1969). As increasing numbers of Spanish and Mexican people, and the later Americans during the Gold Rush, settled in the area, the Native populations diminished as they were displaced or decimated by disease (Carrico and Taylor 1983). By 1821, Mexico had gained independence from Spain and the northern territories were subject to political repercussions. By 1834, all of the mission lands had been removed from the control of the Franciscan Order under the Acts of Secularization. Without proper maintenance, the missions quickly began to disintegrate, and after 1836, missionaries ceased to make regular visits inland to minister the needs of the native peoples (Engelhardt 1921). Large tracts of land Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–9 continued to be granted to those who applied or had gained favor with the Mexican government. Grants of land were also made to settle government debts. The Rancho Period represents the time between 1821 and 1848. By 1821, Mexico had gained independence from Spain and the northern territories were subject to political repercussions. By 1834, all of the mission lands had been removed from the control of the Franciscan Order under the Acts of Secularization (Engelhardt 1921). Numerous Mexican land tracts, or rancheros, were established throughout coastal and interior California. California was invaded by United States troops during the Mexican-American War of 1846 to 1848. The acquisition of strategic Pacific ports and California land was one of the principal objectives of the war (Price 1967). At the time, the inhabitants of California were practically defenseless, and they quickly surrendered to the United States Navy in July 1847 (Bancroft 1886). In 1848, the Treaty of Guadalupe Hidalgo granted sovereignty over Alta California, New Mexico, and Arizona to the United States, which began the American Settlement Period. The new colonial order soon seized power in California with disastrous results for the native people (Castillo 1978). European control over Alta California had been concentrated along the coast, but with the great influx of American colonists seeking land and mineral resources, the inland became more populated and native populations were displaced from more of their lands. Conflicts between the Native Americans and the intruding white colonists led to the establishment of reservations for some villages by executive order. The cattle ranchers of the “counties” of southern California prospered during the cattle boom of the early 1850s. Raising cattle soon declined, however, contributing to the expansion of agriculture. The completion of the transcontinental railroad in 1869 encouraged developers, land speculators, and colonists to invest and live in southern California. Orange County’s economy changed from stock raising to farming, and growing grain or citrus crops replaced the raising of cattle in many of the county’s inland valleys (Blick 1976; Elliott 1965). General History of the Orange Area As part of a petition to the Spanish government in 1810, Jose Antonio Yorba and his cousin Juan Pablo Peralta were granted 78,941 acres of grazing land previously granted to Juan Pablo Grijalva, their uncle and father, respectively, “[t]he first land user in the Orange area … a retired Spanish soldier” (Maniery et al. 2006). “Yorba chose the flatlands near the Santa Ana River at what became known as Olive. His son[s] … built adobes on the hills by Olive, out of the flood plain … [which] became known as Santa Ana Ranch and served as the rancho headquarters” (Maniery et al. 2006). “Yorba and Peralta each had nine children. As these descendants married, the family expanded and settled on different parts of the rancho” (Maniery et al. 2006). “In the 1860s, the Yorba rancho was subdivided by heirs of the original grantees and [lawyers] Andrew Glassell and Alfred Chapman … took 4,000 acres in lieu of attorneys’ fees” (Maniery et al. 2006). Ten- to 40-acre parcels were formed from the subdivided land and placed for sale in 1870 as the “Richland Farm Lots” (Maniery et al. 2006). “Glassell’s brother, Captain Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–10 William Glassell, surveyed and platted a new town named Richland in 1871; the name was changed to Orange two years later to satisfy postal requirements” Maniery et al. 2006) since “there was already a Richland, California, up near Sacramento” (Brigandi 2011). Orange was incorporated in 1888 and “was primarily an agricultural community until the 1950s, when modern suburban development arrived” (Brigandi 2011). “At the time of incorporation, Orange had a population of 600, and was a 3.1 square mile city bounded by” Batavia Street, Collins Avenue, La Veta Avenue, and Santiago Creek (City of Orange n.d.). Profitable crops included grapes, wheat, oats, barley, corn, fruit trees, a variety of vegetables, tobacco, and hops (Brigandi 2011), “but by 1920, oranges had become the city’s premier crop” (City of Orange n.d.). The population of the city grew during World War II, with “thousands of servicemen … [being] trained in Southern California” (City of Orange n.d.). “After World War II, returning soldiers and a massive influx of new residents to the state” contributed to the population boom and “Orange, located centrally in the Los Angeles Basin” became an attractive option and “its remaining open and agricultural space … [was developed] into bedroom communities” (Maniery et al. 2006). Orange continued to expand throughout the subsequent decades and “is home to thousands of businesses, ranging from major Fortune 500 companies to family-owned stores,” in addition to Chapman University and Santiago Canyon College (City of Orange n.d.). Brief History of the Project Based on aerial photographs from as early as 1938, the property appears to contain a just- planted citrus grove surrounded by more mature and developed citrus groves. Except for the maturing of the trees within the project, little change is evident on and around the property through 1960. By 1963, residential development of neighboring parcels was visible on aerial photographs but the subject property remained agricultural. By 1966, the citrus grove on the property had been removed, and Cambridge Street along the western boundary of the project was visible. The subject property appears to have remained vacant through 1970, although by that time, all adjacent properties appear to have been developed. By 1972, the commercial/office structure that is currently on the subject property had been constructed. A review of historic newspapers and online information indicates that by 1973 the commercial/office structure and the associated parking lot were used by Pacific Telephone of Santa Ana (Los Angeles Times 1973). Recent google street view photographs (2008-2022) show signs on and around the building for AT&T and associated telecommunication utility and maintenance vehicles within the gated parking lot until 2018. Although utilized by telephone utility companies under different names, Pacific Telephone of Santa Ana operated under AT&T until 1984, while later acquisitions brought the utility back under the AT&T umbrella. According to an article on the California State University, Dominguez Hills (CSUDH) website, “Alexander Graham Bell patented the telephone in 1876 and formed Bell Telephone which licensed local telephone exchanges in major US cities” (CSUDH n.d.). Pacific Telephone of Santa Ana was part of the larger Pacific Telephone and Telegraph Company which operated the region’s Bell System to provide local service (CSUDH n.d.) As with most of the Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–11 telephone companies throughout the United States, the utility was part of American Telephone and Telegraph (AT&T) which was formed in 1885 to connect local Bell companies. AT&T was a monopoly that dominated phone service throughout the twentieth century. AT&T was forced to break up its monopoly in 1984 of local “Regional Bell Operating Companies” (RBOC) networks but retained its long-distance control. This led to Pacific Telephone and Telegraph Company becoming known as Pacific Bell Telephone Company (CSUDH n.d.). Another of these smaller local utilities, the Southwestern Bell Corporation (SBC) was formed and expanded throughout the 1990s, acquiring other RBOCs and eventually AT&T in 2005. After this acquisition, SBC assumed the name AT&T (AT&T.com n.d; CSUDH n.d.). As such, it appears the development currently within the project was constructed for the use of the local telephone utility company and continued in that capacity until around 2018. 1.4 Results of the Archaeological Records Search An archaeological records search for the project and the surrounding area within a one- mile radius conducted by BFSA at the SCCIC at CSU Fullerton. The SCCIC records search results indicated that three resources, all historic in age, are located within a one-mile radius of the project (Table 1.4–1). These resources include the Old Towne Orange Historic District, a single-family residence, and Orange High School. None of these resources are mapped within the subject property. The records search results also indicated that 11 cultural resource studies have been conducted within a one-mile radius of the project, one of which is located within the subject property (Mason 1997). The Mason study consisted of a records search and literature review for the modification of a cellular phone tower (Mason 1997). As such, it did not include a survey and no resources were reported within the subject property. The complete records search results can be found in Appendix C. Table 1.4–1 Cultural Resources Within One Mile of the Project Site Number Site Type P-30-159932 Old Towne Orange Historic District P-30-162488 Historic single-family residence P-30-177662 Historic Orange High School Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–12 BFSA also reviewed the following sources to help facilitate a better understanding of the historic use of the property: • The National Register of Historic Places index • Historic USGS data • Aerial photographs (1938 through 2022) These sources did not indicate the presence of archaeological resources within the project. Again, the property appears to have been agricultural from 1938 to 1966. The area surrounding the subject property began to transition from agricultural to residential and commercial between 1952 and 1963. By the 1963 aerial photograph, residential tracts within the project vicinity began to be developed; however, Katella Avenue, although present, is not lined with commercial businesses as it is today. The current development within the project was constructed between 1970 and 1972 (Plates 1.4–1 through 1.4–2). By 1972, the area surrounding the property was more developed with commercial structures lining Katella Avenue and adjacent side streets containing residential subdivisions. However, as evident by the 1972 aerial, adjacent properties to the subject property were not yet fully developed. By 1980, the general project vicinity appears much like it does today. BFSA also requested an SLF search from the NAHC to identify any sacred sites or locations of religious or ceremonial importance within the project. The NAHC search was returned with negative results and has been forwarded to the City of Orange. All correspondence is provided in Appendix D. Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–15 1.5 Applicable Regulations Resource importance is assigned to districts, sites, buildings, structures, and objects that possess exceptional value or quality illustrating or interpreting the heritage of Orange County in history, architecture, archaeology, engineering, and culture. A number of criteria are used in demonstrating resource importance. Specifically, the criteria outlined in CEQA and City of Orange environmental guidelines provide the guidance for making such a determination. The following sections detail the criteria that a resource must meet in order to be determined important. 1.5.1 California Environmental Quality Act According to CEQA (§15064.5a), the term “historical resource” includes the following: 1) A resource listed in or determined to be eligible by the State Historical Resources Commission for listing in the California Register of Historical Resources (CRHR) (Public Resources Code SS5024.1, Title 14 CCR. Section 4850 et seq.). 2) A resource included in a local register of historical resources, as defined in Section 5020.1(k) of the Public Resources Code or identified as significant in an historical resource survey meeting the requirements of Section 5024.1(g) of the Public Resources Code, shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant. 3) Any object, building, structure, site, area, place, record, or manuscript, which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be an historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing on the CRHR (Public Resources Code SS5024.1, Title 14, Section 4852) including the following: a) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; b) Is associated with the lives of persons important in our past; c) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or d) Has yielded, or may be likely to yield, information important in prehistory or history. Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–16 4) The fact that a resource is not listed in, or determined eligible for listing in the CRHR, not included in a local register of historical resources (pursuant to Section 5020.1(k) of the Public Resources Code), or identified in an historical resources survey (meeting the criteria in Section 5024.1(g) of the Public Resources Code) does not preclude a lead agency from determining that the resource may be an historical resource as defined in Public Resources Code Section 5020.1(j) or 5024.1. According to CEQA (§15064.5b), a project with an effect that may cause a substantial adverse change in the significance of an historical resource is a project that may have a significant effect on the environment. CEQA defines a substantial adverse change as: 1) Substantial adverse change in the significance of an historical resource means physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired. 2) The significance of an historical resource is materially impaired when a project: a) Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its inclusion in, or eligibility for inclusion in the CRHR; or b) Demolishes or materially alters in an adverse manner those physical characteristics that account for its inclusion in a local register of historical resources pursuant to Section 5020.1(k) of the Public Resources Code or its identification in an historical resources survey meeting the requirements of Section 5024.1(g) of the Public Resources Code, unless the public agency reviewing the effects of the project establishes by a preponderance of evidence that the resource is not historically or culturally significant; or, c) Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its eligibility for inclusion in the CRHR as determined by a lead agency for purposes of CEQA. Section 15064.5(c) of CEQA applies to effects on archaeological sites and contains the following additional provisions regarding archaeological sites: 1. When a project will impact an archaeological site, a lead agency shall first determine whether the site is an historical resource, as defined in subsection (a). 2. If a lead agency determines that the archaeological site is an historical resource, it shall refer to the provisions of Section 21084.1 of the Public Resources Code, Section Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–17 15126.4 of the guidelines, and the limits contained in Section 21083.2 of the Public Resources Code do not apply. 3. If an archaeological site does not meet the criteria defined in subsection (a), but does meet the definition of a unique archaeological resource in Section 21803.2 of the Public Resources Code, the site shall be treated in accordance with the provisions of Section 21083.2. The time and cost limitations described in Public Resources Code Section 21083.2 (c-f) do not apply to surveys and site evaluation activities intended to determine whether the project location contains unique archaeological resources. 4. If an archaeological resource is neither a unique archaeological nor historical resource, the effects of the project on those resources shall not be considered a significant effect on the environment. It shall be sufficient that both the resource and the effect on it are noted in the Initial Study or Environmental Impact Report, if one is prepared to address impacts on other resources, but they need not be considered further in the CEQA process. Section 15064.5 (d) and (e) contain additional provisions regarding human remains. Regarding Native American human remains, paragraph (d) provides: (d) When an initial study identifies the existence of, or the probable likelihood of, Native American human remains within the project, a lead agency shall work with the appropriate Native Americans as identified by the NAHC as provided in Public Resources Code SS5097.98. The applicant may develop an agreement for treating or disposing of, with appropriate dignity, the human remains and any items associated with Native American burials with the appropriate Native Americans as identified by the NAHC. Action implementing such an agreement is exempt from: 1) The general prohibition on disinterring, disturbing, or removing human remains from any location other than a dedicated cemetery (Health and Safety Code Section 7050.5). 2) The requirements of CEQA and the Coastal Act. 1.5.2 City of Orange Register of Historic Resources The City of Orange General Plan does discuss the city creating its own “Local Register of Historic Resources (Historic Register)” (City of Orange 2010). However, the General Plan states that: The criteria for listing in the Historic Register will be the same as for listing in the CRHR, as such criteria may be updated from time to time by the State of California. To be listed in the Historic Register, a property or district must demonstrate Cultural Resources Study for the 901East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 1.0–18 eligibility under one or more of four basic significance criteria, be representative of at least one theme identified in the Historic Context Statement, and retain substantial integrity. (City of Orange 2010) A review of the City of Orange Historic Context Statement identified the following themes: Colonization, Early Settlement, Industry, Immigration and Ethnic Diversity, Interwar Development, and Postwar Development. Within these themes, places of particular interest include Old Towne, El Modena, Cypress Street Barrio, and three Eichler tracts; physical developments of particular interest include the railroad, packing houses, private homes, and civic buildings; and social developments of particular interest include labor issues and segregation. (Chattel Architecture, Planning & Preservation, Inc 2006) Although the General Plan does discuss the creation of the City’s own local register. It does not appear any such register or additional criteria has been established, and it is clear the basis of any such local designation or criteria is the CRHR. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 2.0–1 2.0 RESEARCH DESIGN The primary goal of the research design is to attempt to understand the way in which humans have used the land and resources within the project area through time, as well as to aid in the determination of resource significance. For the current project, the study area under investigation is west-central Orange County. The scope of work for the cultural resources study conducted for the 901 East Katella Avenue Project included the survey of a 2.71-acre area. Given the area involved, the research design for this project was focused upon realistic study options. Since the main objective of the investigation was to identify the presence of and potential impacts to cultural resources, the goal is not necessarily to answer wide-reaching theories regarding the development of early southern California, but to investigate the role and importance of identified resources. Nevertheless, the assessment of the significance of a resource must take into consideration a variety of characteristics, as well as the ability of a resource to address regional research topics and issues. Although elementary resource evaluation programs are limited in terms of the amount of information available, several specific research questions were developed that could be used to guide the initial investigations of any observed cultural resources. The following research questions take into account the size and location of the project discussed above. Research Questions: • Can located cultural resources be associated with a specific time period, population, or individual? • Do the types of any located cultural resources allow a site activity/function to be determined from a preliminary investigation? What are the site activities? What is the site function? What resources were exploited? • How do located sites compare to others reported from different surveys conducted in the area? • How do located sites fit existing models of settlement and subsistence for valley environments of the region? The research pertaining to the historic building focuses upon the built environment and those individuals associated with the ownership, design, and construction of the building within the project footprint. Several specific research questions were developed that could be used to guide the initial investigations of any observed historic resources: • Can the building be associated with any significant individuals or events? • Is the building representative of a specific type, style, or method of construction? • Is the building associated with any nearby structures? Does the building, when studied with the nearby structures, qualify as a contributor to a potential historic district? Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 2.0–2 • Was the building designed or constructed by a significant architect, designer, builder, or contractor? Data Needs At the survey level, the principal research objective is a generalized investigation of changing settlement patterns in both the prehistoric and historic periods within the study area. The overall goal is to understand settlement and resource procurement patterns of the project area occupants. Therefore, adequate information on site function, context, and chronology from an archaeological perspective is essential for the investigation. The fieldwork and archival research were undertaken with the following primary research goals in mind: 1) To identify cultural resources occurring within the project; 2) To determine, if possible, site type and function, context of the resource(s), and chronological placement of each cultural resource identified; 3) To place each cultural resource identified within a regional perspective; and 4) To provide recommendations for the treatment of each cultural resources identified. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–1 3.0 ANALYSIS OF PROJECT EFFECTS The cultural resources study of the project consisted of an institutional records search, an intensive cultural resource survey of the entire 2.71-acre project, and the preparation of this technical report. This study was conducted in conformance with City of Orange environmental guidelines, Section 21083.2 of the California Public Resources Code, and CEQA. Statutory requirements of CEQA (Section 15064.5) were followed for the identification and evaluation of resources. Specific definitions for archaeological resource type(s) used in this report are those established by the State Historic Preservation Office (SHPO 1995). 3.1 Methods 3.1.1 Survey Methods The survey methodology employed during the current investigation followed standard archaeological field procedures and was sufficient to accomplish a thorough assessment of the project. The field methodology employed for the project included walking evenly spaced survey transects set approximately five meters apart while visually inspecting the ground surface. Photographs documenting survey areas and overall survey conditions were taken frequently. 3.1.2 Archival Research Records relating to the ownership and developmental history of this project were sought to identify any associated historic persons, historic events, or architectural significance. Records research was conducted at the BFSA research library, the SCCIC, the City of Orange, and the Assessor/County Recorder/County Clerk. 3.1.3 Historic Structure Assessment Methods for evaluating the integrity and significance of the historic building at 901 East Katella Avenue included photographic documentation and a review of available property records. During the survey, photographs were taken of all building elevations. The photographs were used to complete an architectural description of the building. The original core structure and all modifications made to the building since its initial construction were also documented. The current setting of the building was compared to the historical setting of the property. This information was combined with the archival research in order to evaluate the buildings’ seven aspects of integrity, as well as their potential significance under CEQA guidelines. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–2 3.2 Results of the Field Survey Staff archaeologist Mary Chitjian conducted the archaeological survey for the 901 East Katella Avenue Project on October 6, 2022. The archaeological survey of the property was an intensive reconnaissance consisting of a series of survey transects across the subject property. Survey conditions were generally fair; however, the ground surface was not visible throughout the survey area due to the presence of a building and associated hardscape, which comprised the entirety of the property (Plates 3.2–1 and 3.2–2). The existing commercial/office building, and asphalt parking lots covered and majority of the subject property with only a few planters and landscaped areas providing a view of the exposed ground. According to aerial photographs the current development within the project is just older than 50 years having been developed sometime between 1970 and 1972. As such, the building found within the project was recorded as Site Temp-1 according to the OHP’s manual, Instructions for Recording Historical Resources, using Department of Parks and Recreation (DPR) forms (Appendix B). Plate 3.2–1: Overview of the property, facing southwest. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–3 3.3 Results of Archival Research and Historic Structure Analysis 3.3.1 Description of Surveyed Resources The 901 East Katella Avenue building qualifies as an historic-era resource that must be evaluated under CRHR criteria. The following section provides the pertinent field results for the significance evaluation for the building, which was conducted in accordance with City of Orange guidelines and cultural resource evaluation protocols. At the time of the survey, the building found within the southwestern corner of the property was boarded up and vacant. However, as previously discussed it was in use as late as 2018. The building at 901 East Katella Avenue is a vernacular ‘T-shaped’ office/commercial building (Figure 3.3–1). The building exhibits a flat roof with shallow coping. The HVAC and other equipment is located on the roof behind a screened access area. The façade of the main structure is visually broken-up by large-rectangular brick clad panels while a central rectangular wing extrudes south from the center of the building towards Katella Avenue (Plate 3.3–1). The central wing is not adorned with the brick panels. Rather, the unadorned façade is broken up by small tinted vertical windows extending almost the entire height of the elevations (Plate 3.3–2). The main entrances to the building are recessed on the east and west façades of the central wing (Plate 3.3–3). Additional entrances are situated along the northern façade allowing direct access to the parking lot. The parking lot which is situated north and east of the structure is covered in asphalt. Entrance to the parking lot is possible from both Katella Avenue and Cambridge Street; however, both access points contain security gates (Plate 3.3–4).

A review of the City of Orange’s eTRAKIT system shows that a number of permits for electrical, plumbing, underground equipment, and signage have been processed for the property. However, the most notable regarding the visual representation of the structure include handicap (ADA) access ramps which were added to the structure’s entrances in 1989, 1994, and 1998. A cell tower was added to the property after 1997. Air conditioning units were added to the roof in 1998. In 2013, a canopy was added to the equipment enclosure situated on the eastern façade of the building (Plate 3.3–5). 3.3.2 Architectural Context The 901 East Katella Avenue building contains architectural inspiration from International Style architecture. The term International Style was coined by Russell Hitchcock and Philip Johnson (Christopher A. Joseph and Associates 2009). According to the City of San Diego Modernism Historic Context Statement (Modernism Context Statement) (City of San Diego 2007): The International style was a major world-wide architectural trend of the 1920s and 30s and reflects the formative decades of Modernism prior to World War II. Although the International style originated in Western Europe, it transcended any national or regional identity because International style architecture made no Plate 3.3–5: Overview of the eastern and northern facades showing the equipment enclosure, cell tower, ADA ramps, and the equipment screen on the roof. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–8 reference to local vernaculars or traditional building forms. The style quickly migrated to the United States as architects from Europe fled prior to WWII. In Los Angeles, immigrant architects Rudolph Schindler and Richard Neutra were instrumental in popularizing the International style. (City of San Diego 2007) As the International Style grew in popularity following WWII, two trends emerged based on the philosophies of Bauhaus leaders Walter Gropus and Mies van der Rohe (Christopher A. Joseph and Associates 2009). Gropus inspired architecture focused on function featuring screened walls, steel frames, and external glass walls without interruption. The Miesien tradition reflected a trend of “less is more” with three subtypes: skyscrapers composed of glass curtain walls, glass and steel pavilions, or the modular office building (Christopher A. Joseph and Associates 2009). Although the two trends deviated from each other in some respects, both included character-defining features consisting of square and rectangular building footprints, horizontal lines of perspectives, balance of regularity, reinforced concrete and steel construction, unadorned smooth wall surfaces separated by steel beams used as an organizational device, limited ornamentation or decoration, flat roofs without overhang, simple cubic or extruded rectangular forms, horizontal bands of windows, and strong right angles. Predominant building materials include concrete, smooth stucco, brick, and glass (City of San Diego 2007; Christopher A. Joseph and Associates 2009). The building found at 901 East Katella Avenue most prominently appears to have been influenced by Mies in its simplicity of design. The large-rectangular, brick-clad panels attempt to mimic the separation and organization often represented on similar structures by steel beams and horizontal ribbons of windows or blank panels. The Riverside modernism context study identifies the 1965 Police Department found at 4102 Orange Street, in Riverside, as a good example of the Miesien tradition that possesses character-defining features that closely resemble those the 901 East Katella Avenue building possesses (Plate 3.3–6). However, the building at 901 East Katella Avenue is not as successful at representing the style. Instead of the brick façade being broken up and organized by beams protruding from the façade, the brick panels found at the 901 East Katella Avenue building are simply laid on top of the façade. In addition, the bricks found on the panels of the 901 East Katella Avenue building are not uniform in color, shade, or size. As such, the panels found on the 901 East Katella Avenue building add to and create a sense of adornment. In contrast, the Riverside Police department is able to convey a lack of adornment by use of brick separated by beams. Further, the Riverside Police department does contain two facades with ribbons of inset windows whereas the 901 East Katella Avenue building is severely lacking in fenestration. Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–9 3.3.3 Significance Evaluations CEQA guidelines (Section 15064.5) address archaeological and historic resources, noting that physical changes that would demolish or materially alter in an adverse manner those characteristics that convey the historic significance of the resource and justify its listing on inventories of historic resources are typically considered significant impacts. Because demolition of the building located at 901 East Katella Avenue would require approval from the City of Orange as part of the proposed project, CEQA eligibility criteria were used to evaluate the subject property as a potentially historic building. Therefore, criteria for listing on the CRHR were used to measure the significance of the resources. Integrity Evaluations When evaluating a historic resource, integrity is the authenticity of the resource’s physical identity clearly indicated by the retention of characteristics that existed during its period of significance. It is important to note that integrity is not the same as condition. Integrity directly relates to the presence or absence of historic materials and character-defining features, while condition relates to the relative state of physical deterioration of the resource. In most instances, integrity is more relevant to the significance of a resource than condition; however, if a resource is in such poor condition that original materials and features may no longer be salvageable, then the resource’s integrity may be adversely impacted.

(Image courtesy of Google Street View) Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–10 In order to determine whether or not the building at 901 East Katella Avenue is eligible for listing, CRHR eligibility criteria were used. Furthermore, BFSA based the review upon the recommended criteria listed in the National Register Bulletin No. 15: How to Apply the National Register Criteria for Evaluation (Andrus and Shrimpton 2002). This review is based upon the evaluation of integrity of the buildings followed by the assessment of distinctive characteristics. 1. Integrity of Location [refers to] the place where the historic property was constructed or the place where the historic event occurred (Andrus and Shrimpton 2002). Integrity of location was assessed by reviewing historical records and aerial photographs in order to determine if the buildings had always existed at their present locations or if they had been moved, rebuilt, or their footprints significantly altered. Historical research revealed that the 901 East Katella Avenue building is located where it was initially constructed between 1970 and 1972. As such, the building does retain integrity of location 2. Integrity of Design [refers to] the combination of elements that create the form, plan, space, structure, and style of a property (Andrus and Shrimpton 2002). Integrity of design was assessed by evaluating the spatial arrangement of the building and any architectural features present. The building was clearly influenced by the International Style of architecture and Miesien tradition. However, it is not a good example of the style. The building lacks the horizontal bands of windows or blank unadorned panels separated by steel beams. Rather, the building attempts to emulate this pattern of window/panel and beams by use of brick clad panels set on top of the façade to create a similar type of separation. Unlike the Riverside Police station where brick façades were organized by protruding beams, the 901 East Katella building attempts to mimic this feature by placing the panels on top of the building’s smooth façade. In addition, the use of differing shades and size of brick set on top of the white façade introduces adornment to the walls. Further, the integrity of design has been hindered by the addition of ADA ramps to all entrances, equipment to the roof, and a covered equipment shed to the eastern façade. As such the 901 East Katella Avenue structure does not possess integrity of design. 3. Integrity of Setting [refers to] the physical environment of a historic property. Setting includes elements such as topographic features, open space, viewshed, landscape, vegetation, and artificial features (Andrus and Shrimpton 2002). Integrity of setting was assessed by inspecting the elements of the property, which include topographic features, open space, views, landscape, vegetation, man-made features, and relationships between buildings and other features. The building was constructed between 1970 and 1972. In the years leading up to the construction of the building, the Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–11 surrounding area transformed from agricultural to residential and commercial. The building was constructed during a period of transition. Although commercial and residential properties were located surrounding the property at the time of construction, based on the aerial photographs, the setting was not fully fleshed out until 1980. Further, improvements to the Katella Avenue commercial corridor have continued since the 1980s and the addition of a large cell tower within the property further diminishes the setting. Therefore, the property does not possess integrity of setting. 4. Integrity of Materials [refers to] the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property (Andrus and Shrimpton 2002). Integrity of materials was assessed by determining the presence or absence of original building materials, as well as the possible introduction of materials that may have altered the architectural design of the buildings. Although additions to the property have added to the building in way of an equipment shed, ADA access, and roof-top HVAC system, the materials present on the structure do retain an overall integrity. Therefore the 901 East Katella Avenue building does possess integrity of materials. 5. Integrity of Workmanship [refers to] the physical evidence of the labor and skill of a particular culture or people during any given period in history (Andrus and Shrimpton 2002). Integrity of workmanship was assessed by evaluating the quality of the architectural features present in the buildings. Again, despite being influenced by the modular office subtype of the Miesien tradition under the International Style of architecture, the building is not a good example of the style. As such, the 901 East Katella Building does not possess integrity of workmanship. 6. Integrity of Feeling [refers to] a property’s expression of the aesthetic or historic sense of a particular period of time (Andrus and Shrimpton 2002). Integrity of feeling was assessed by evaluating whether or not the resources’ features, in combination with their setting, conveyed a historic sense of the property during the period of construction. As noted previously, the integrity of setting for the building was not fully established at the time of construction and not apparent on aerial photographs until around 1980. Further, the commercial corridor of Katella Avenue has continued to be improved. Therefore, the 901 East Katella Avenue buildings do not retain integrity of feeling. 7. Integrity of Association [refers to] the direct link between an important historic event or person and a historic property (Andrus and Shrimpton 2002). Integrity of association was assessed by evaluating the resources’ data or information and their ability to answer any research questions relevant to the history of the Orange area or Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–12 the state of California. Research indicates that the 901 East Katella Avenue property is not associated with any significant persons or events. The building is associated with the Pacific Telephone Company of Santa Ana and later by AT&T after SBC acquired Pacific Bell Telephone Company. As such, it was one of many buildings utilized by the utility company. Therefore, the 901 East Katella Avenue building does not, and has not ever possessed integrity of association. CRHR Evaluation For a historic resource to be eligible for listing on the CRHR, the resource must be found significant at the local, state, or national level, under one or more of the following criteria: • CRHR Criterion 1: It is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage. Historical research of the 901 East Katella Avenue building found that it was associated with the Pacific Telephone Company of Santa Ana and later by AT&T after SBC acquired Pacific Bell Telephone Company. Although developed during the Postwar Development period, the building lacks integrity and again is one of many buildings utilized by the utility company. Therefore, it is not associated with any notable historic events and is not eligible for designation under CRHR Criterion 1. • CRHR Criterion 2: It is associated with the lives of persons important in our past. Historical research revealed that the 901 East Katella Avenue building is not associated with any persons important in our past. Again, the building was utilized by the phone company and not associated with any singular individual. Therefore, 901 East Katella Avenue is not eligible for designation under CRHR Criterion 2. • CRHR Criterion 3: It embodies the distinctive characteristics of a type, period, region, or method of construction; represents the work of an important creative individual; or possesses high artistic values. The 901 East Katella Avenue building is obviously influenced by the modular office subtype of the Miesien tradition under the International Style of architecture. The buildings rectangular floor plan, flat unadorned roof, central cubic extruding wing convey the buildings architectural influences. However, the building attempts to mimic Cultural Resources Study for the 901 East Katella Avenue Project –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 3.0–13 the pattern of window/panel organized by beams with the use of brick clad panels set on top of the façade to emulate this separation. Further, the building is a common example of early 1970s office/commercial structures and modifications consisting of ADA access ramps, addition of an equipment enclosure, and cell tower to the property have also diminished the architectural integrity of the building. As such, the 901 East Katella Avenue building is not eligible for designation under CRHR Criterion 3. • CRHR Criterion 4: It has yielded, or may be likely to yield, information important in prehistory or history. The research conducted for this study revealed that the 901 East Katella Avenue Building is not associated with any significant persons or events and was not constructed using unique or innovative methods of construction. Therefore, the building is not likely to yield any additional information about the history of Orange or the state of California. Therefore, the 901 East Katella Avenue building is not eligible for designation under CRHR Criterion 4. 3.4 Discussion/Summary The survey resulted in the identification of one structure that is just over 50 years old that is not considered significant under CEQA criteria nor eligible for the CRHR. The building does not appear to have been altered much; however, it is a common example of an early 1970s office/commercial structure possessing limited integrity. The building was constructed between 1970 and 1972 and was first used by the Pacific Telephone Company of Santa Ana and later by AT&T after SBC acquired the Pacific Bell Telephone Company. As such, it was one of many buildings utilized by the utility company. Therefore, the building is not considered to have been associated with any significant events or individuals. Further, the structure is a standard office/commercial building constructed during the early 1970s. Although influenced by the International Style of architecture, it is not a good example and is not considered architecturally important. Finally, the building does not, and is not likely to, yield any information important to the history of the region. As such, the building at 901 East Katella Avenue is not considered a “Historical Resource,” and its removal will not require any further study. Cultural Resources Study for the 901 East Katella Avenue Project ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 4.0–1 4.0 RECOMMENDATIONS The cultural resources study for the 901 East Katella Avenue Project, was completed in accordance with City of Orange report guidelines and CEQA significance evaluation criteria. Although one commercial/office structure constructed between 1970 and 1972 was identified, it is not considered a “Historical Resource” under CEQA critera. Therefore no significant or CRHR eligible resources exist within the project. As such, no potential impacts to significant cultural resources are associated with the proposed development of the project. Furthermore, the records search results indicated that only three historic resources, all associated with the built environment, have been recorded within a one-mile radius of the project, and no prehistoric resources have ever been recorded within the vicinity of the project. Due to the disturbed nature of the property as a result of previous agricultural use, clearing, grading, and the 1970s development within the subject property, there is little likelihood that archaeological deposits are present within the project boundaries. Therefore, mitigation measures are not recommended and the project should be allowed to proceed without additional archaeological studies.

Mr. Smith has been principal investigator on the following select projects, except where noted. Downtown San Diego Mitigation and Monitoring Reporting Programs: Large numbers of downtown San Diego mitigation and monitoring projects, some of which included Broadway Block (2019), 915 Grape Street (2019), 1919 Pacific Highway (2018), Moxy Hotel (2018), Makers Quarter Block D (2017), Ballpark Village (2017), 460 16th Street (2017), Kettner and Ash (2017), Bayside Fire Station (2017), Pinnacle on the Park (2017), IDEA1 (2016), Blue Sky San Diego (2016), Pacific Gate (2016), Pendry Hotel (2015), Cisterra Sempra Office Tower (2014), 15th and Island (2014), Park and G (2014), Comm 22 (2014), 7th and F Street Parking (2013), Ariel Suites (2013), 13th and Marker (2012), Strata (2008), Hotel Indigo (2008), Lofts at 707 10th Avenue Project (2007), Breeza (2007), Bayside at the Embarcadero (2007), Aria (2007), Icon (2007), Vantage Pointe (2007), Aperture (2007), Sapphire Tower (2007), Lofts at 655 Sixth Avenue (2007), Metrowork (2007), The Legend (2006), The Mark (2006), Smart Corner (2006), Lofts at 677 7th Avenue (2005), Aloft on Cortez Hill (2005), Front and Beech Apartments (2003), Bella Via Condominiums (2003), Acqua Vista Residential Tower (2003), Northblock Lofts (2003), Westin Park Place Hotel (2001), Parkloft Apartment Complex (2001), Renaissance Park (2001), and Laurel Bay Apartments (2001). BFSA Environmental Services, a Perennial Company, 2 1900 and 1912 Spindrift Drive: An extensive data recovery and mitigation monitoring program at the Spindrift Site, an important prehistoric archaeological habitation site stretching across the La Jolla area. The project resulted in the discovery of over 20,000 artifacts and nearly 100,000 grams of bulk faunal remains and marine shell, indicating a substantial occupation area (2013-2014). San Diego Airport Development Project: An extensive historic assessment of multiple buildings at the San Diego International Airport and included the preparation of Historic American Buildings Survey documentation to preserve significant elements of the airport prior to demolition (2017-2018). Citracado Parkway Extension: A still-ongoing project in the city of Escondido to mitigate impacts to an important archaeological occupation site. Various archaeological studies have been conducted by BFSA resulting in the identification of a significant cultural deposit within the project area. Westin Hotel and Timeshare (Grand Pacific Resorts): Data recovery and mitigation monitoring program in the city of Carlsbad consisted of the excavation of 176 one-square-meter archaeological data recovery units which produced thousands of prehistoric artifacts and ecofacts, and resulted in the preservation of a significant prehistoric habitation site. The artifacts recovered from the site presented important new data about the prehistory of the region and Native American occupation in the area (2017). The Everly Subdivision Project: Data recovery and mitigation monitoring program in the city of El Cajon resulted in the identification of a significant prehistoric occupation site from both the Late Prehistoric and Archaic Periods, as well as producing historic artifacts that correspond to the use of the property since 1886. The project produced an unprecedented quantity of artifacts in comparison to the area encompassed by the site, but lacked characteristics that typically reflect intense occupation, indicating that the site was used intensively for food processing (2014-2015). Ballpark Village: A mitigation and monitoring program within three city blocks in the East Village area of San Diego resulting in the discovery of a significant historic deposit. Nearly 5,000 historic artifacts and over 500,000 grams of bulk historic building fragments, food waste, and other materials representing an occupation period between 1880 and 1917 were recovered (2015-2017). Archaeology at the Padres Ballpark: Involved the analysis of historic resources within a seven-block area of the “East Village” area of San Diego, where occupation spanned a period from the 1870s to the 1940s. Over a period of two years, BFSA recovered over 200,000 artifacts and hundreds of pounds of metal, construction debris, unidentified broken glass, and wood. Collectively, the Ballpark Project and the other downtown mitigation and monitoring projects represent the largest historical archaeological program anywhere in the country in the past decade (2000-2007). 4S Ranch Archaeological and Historical Cultural Resources Study: Data recovery program consisted of the excavation of over 2,000 square meters of archaeological deposits that produced over one million artifacts, containing primarily prehistoric materials. The archaeological program at 4S Ranch is the largest archaeological study ever undertaken in the San Diego County area and has produced data that has exceeded expectations regarding the resolution of long-standing research questions and regional prehistoric settlement patterns. Charles H. Brown Site: Attracted international attention to the discovery of evidence of the antiquity of man in North America. Site located in Mission Valley, in the city of San Diego. Del Mar Man Site: Study of the now famous Early Man Site in Del Mar, California, for the San Diego Science Foundation and the San Diego Museum of Man, under the direction of Dr. Spencer Rogers and Dr. James R. Moriarty. Old Town State Park Projects: Consulting Historical Archaeologist. Projects completed in the Old Town BFSA Environmental Services, a Perennial Company, 3 State Park involved development of individual lots for commercial enterprises. The projects completed in Old Town include Archaeological and Historical Site Assessment for the Great Wall Cafe (1992), Archaeological Study for the Old Town Commercial Project (1991), and Cultural Resources Site Survey at the Old San Diego Inn (1988). Site W-20, Del Mar, California: A two-year-long investigation of a major prehistoric site in the Del Mar area of the city of San Diego. This research effort documented the earliest practice of religious/ceremonial activities in San Diego County (circa 6,000 years ago), facilitated the projection of major non-material aspects of the La Jolla Complex, and revealed the pattern of civilization at this site over a continuous period of 5,000 years. The report for the investigation included over 600 pages, with nearly 500,000 words of text, illustrations, maps, and photographs documenting this major study. City of San Diego Reclaimed Water Distribution System: A cultural resource study of nearly 400 miles of pipeline in the city and county of San Diego. Master Environmental Assessment Project, City of Poway: Conducted for the City of Poway to produce a complete inventory of all recorded historic and prehistoric properties within the city. The information was used in conjunction with the City’s General Plan Update to produce a map matrix of the city showing areas of high, moderate, and low potential for the presence of cultural resources. The effort also included the development of the City’s Cultural Resource Guidelines, which were adopted as City policy. Draft of the City of Carlsbad Historical and Archaeological Guidelines: Contracted by the City of Carlsbad to produce the draft of the City’s historical and archaeological guidelines for use by the Planning Department of the City. The Mid-Bayfront Project for the City of Chula Vista: Involved a large expanse of undeveloped agricultural land situated between the railroad and San Diego Bay in the northwestern portion of the city.

PURPOSE AND SCOPE OF SERVICES The purpose of this study was to complete an evaluation of the existing geotechnical conditions of the project site with respect to currently anticipated site development. Services provided for this study included the following:  Research and review of available geologic and general information pertinent to the site,  Review of the geotechnical report for the property by Salem Engineering Group, Inc. (2019),  Site reconnaissance,  Site exploration consisting of the excavation, logging, and sampling of three exploratory hollow-stem auger borings and logging and percolation testing of two hollow-stem auger borings,  Collection of relatively undisturbed and bulk soil samples of the onsite materials,  Laboratory testing of the soil samples obtained from the site,  Review and evaluation of site seismicity,  Engineering analyses, and  Compilation of this updated geotechnical and infiltration report which presents our findings, conclusions, and recommendations for site development. The intent of this report is to aid in the assessment of the site for future proposed development from a geotechnical perspective. The professional opinions and geotechnical information contained in this report may need to be updated based upon our review of the final site development plans. These plans should be provided to GeoTek, Inc. (GeoTek) for review when available. 2. SITE DESCRIPTION AND PROPOSED DEVELOPMENT 2.1 SITE DESCRIPTION The subject site is located at 901 East Katella Avenue in the city of Orange, Orange County, California. The site is also identified with Orange County Assessor’s Parcel Number (APN) 375- Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 2 461-41 and consists of a roughly trapezoidal-shaped 2.71-acre property. The parcel is currently occupied by a 20,000 square foot, single-story office building and associated parking lot and other improvements. At the time of our field exploration, the building was vacant. The site has a generally flat topography with a elevations ranging from 229 feet above mean sea level (amsl) to 223 feet amsl descending to the west-southwest. Surface drainage is to the west- southwest. The site is bounded by residential properties on the north, a commercial development on the east, North Cambridge Street on the west, and East Katella Avenue on the south. The general location of the site is shown in Figure 1. The current and proposed improvements on the site are displayed on Figures 2a-b, Exploration Location Maps. 2.2 PROPOSED DEVELOPMENT According to the Conceptual Site Plan, prepared by Bassenian Lagoni Architecture and dated February 16, 2022, the property will be developed with 54 residences consisting of two (2) detached single-family dwellings and twenty-six (26) sets of paired single-family dwellings, parking and drive areas, parks, underground utilities, and other improvements. The structures are anticipated to be two to three stories, of wood-framed construction, and will utilize concrete slab-on-grade floors and shallow spread foundations. Cuts and fills to reach design grades are estimated to be minimal. Minor slopes and perimeter/retaining walls are also expected. In addition, we anticipate that stormwater at the site be managed via relatively shallow infiltration systems. Specific locations, depths, and characteristics of the BMP systems are currently unknown. If site development differs from the assumptions made herein, the recommendations included in this report should be subject to further review and evaluation. Final site development plans should be reviewed by GeoTek when they become available. Additional geotechnical field exploration, analyses and recommendations may be necessary upon review of site development plans. 3. REPORT REVIEW On May 16, 2019, Salem Geotechnical Engineering Group, Inc. (Salem) issued a geotechnical investigation report for the proposed commercial development of the project site. The investigation eight (8) exploratory borings to depths ranging from 5 to 50 feet and three (3) Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 3 borings for percolation testing to depths between 5 and 10 feet. Salem’s exploration suggested that the site is mostly underlain by medium dense/stiff to very dense/hard alluvial deposits. However, localized areas with undocumented fill up to 15 feet in thickness were also noted. No groundwater was encountered during the site investigation and the potential for liquefaction at the site was considered nil. Salem concluded that the property has surficial soils with medium expansion potential, negligible sulfate concentrations, and poor infiltration rates. The logs of the exploratory borings, percolation and infiltration test data, and results of laboratory test results by Salem are included in Appendix A. The approximate locations of Salem’s explorations are shown on the Exploration Location Maps, Figures 2a-b. 4. FIELD EXPLORATION, LABORATORY TESTING, AND PERCOLATION TESTING 4.1 FIELD EXPLORATION GeoTek evaluated the subsurface conditions of the site via three (3) exploratory borings excavated on May 5, 2022 to approximately 19 to 22.5 feet below existing grade. In addition, two (2) percolation test borings approximately five (5) feet deep were advanced within the lower portions of the site (west-southwest side) where stormwater BMP systems may be placed. The borings were drilled with a truck-mounted hollow-stem auger drill rig. The approximate locations of our site explorations and past explorations by Salem are shown on the Exploration Location Maps, Figures 2a-b. Logs of the borings are provided in Appendices A and B. 4.2 LABORATORY TESTING Laboratory testing was performed on selected relatively undisturbed and bulk soil samples collected during the field exploration. The purpose of the laboratory testing was to confirm the field classification of the soil materials encountered and to evaluate the soils physical properties for use in the engineering design and analysis. Results of the laboratory testing program along with a brief description and relevant information regarding testing procedures are included in Appendix C. 4.3 PERCOLATION TESTING Percolation testing was performed at boring locations I-1 and I-2 to assess the infiltration rates of the site soils underlying potential stormwater system areas. The borings were excavated to approximately five (5) feet below the existing grade, which was assumed to be the approximate invert depth of the infiltration systems. The boring diameter was approximately eight inches. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 4 Percolation testing was performed within the lower approximately 20 inches in the borings by a representative of our firm, in general conformance with the Boring Percolation Test Procedure outlined in the Technical Guidance Document Appendix VII (Orange County, 2013). As required, the percolation rates were corrected to account for discharge of water from both the sides and bottom of the borings. This correction was done using the Porchet Method, obtaining the infiltration rates tabulated below: SUMMARY OF RESULTS Boring Observed Infiltration Rate, Kobserved (inches per hour) Measured Infiltration Rate, Kmeasured (inches per hour) I-1 4.2 2.1 I-2 0.04 0.02 As recommended by the referenced Technical Guidance Document (Orange County, 2013), a factor of safety of 2.0 was applied to the observed (field) rates to estimate measured infiltration rates. As shown on the table above, poor to favorable infiltration rates (nil to 2 inches per hour) were encountered at the site. Salem (2019) reported relatively similar findings with variable rates ranging from nil to 0.23 inches per hour. Detailed percolation/infiltration test data is included in Appendix D. It should be noted that the infiltration rates provided above were performed in relatively undisturbed on-site soils. Infiltration rates will vary and are mostly dependent on the underlying consistency of the site soils and relative density. Infiltration rates may be impacted by weight of equipment travelling over the soils, placement of engineered fill and other various factors. GeoTek assumes no responsibility or liability for the ultimate design or performance of the storm water facility. 5. GEOLOGIC AND SOILS CONDITIONS 5.1 REGIONAL SETTING The subject property is situated in the Peninsular Ranges geomorphic province. The Peninsular Ranges province is one of the largest geomorphic units in western North America. Basically, it extends roughly 975 miles from the north and extends from the Transverse Ranges geomorphic province to the tip of Baja California, from north to south. This province varies in width from about 30 to 100 miles. It is bounded on the west by the Pacific Ocean, on the south by the Gulf of California and on the east by the Colorado Desert Province. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 5 The Peninsular Ranges are essentially a series of northwest-southeast oriented fault blocks. Several major fault zones are found in this province. The Elsinore Fault zone and the San Jacinto Fault zone trend northwest-southeast and are found in the near the middle of the province. The San Andreas Fault zone borders the northeasterly margin of the province. More specific to the subject property, Morton, D.M., and Miller, F.K., (2006) map the site to be underlain by old alluvial fan deposits (late to middle Pleistocene age). Additionally, the nearest known active fault to the site is the Elsinore fault- Whittier Section located approximately 7.6 miles to the north. 5.2 GENERAL SOIL/GEOLOGIC CONDITIONS A brief description of the earth materials encountered in our explorations and explorations by Salem (2019) is presented in the following sections. 5.2.1 Undocumented Fill Undocumented fill was encountered in the area of GeoTek’s boring B-1 and Salem’s boring B-5 beneath the existing pavement section to approximately 9 to 15 feet below grade, respectively. The fill is associated to the construction of the existing site improvements and is generally composed of brown to grayish brown, slightly moist clayey sand and poorly graded to well graded sand with silt and some fine gravel. Because of its variable in-place density (ranging from very loose to very dense) and lack of documentation regarding its placement, the fill is considered to be un-engineered, un-compacted material. 5.2.2 Old Alluvial Fan Deposits Old alluvial fan deposits were encountered in our borings and borings by Salem below the fill or existing pavement section and extended to the maximum depth explored of about 50 feet. The old alluvial fan deposits consist of interbedded units of clayey sand, silty sand, sandy clay, and poorly graded to well graded sand with silt and some fine gravel. The alluvium was reddish brown to grayish brown in color, slightly moist to moist, and in a medium dense/stiff to very dense/hard in-place state to the total depth explored, based on our field observations, blow counts, and in-place density determinations. Tests conducted on the most unfavorable units of the alluvium (selected based on blow counts) indicated a negligible to slight potential for collapse upon application of water. Test results obtained by Salem suggest similar findings. The near surface site soils were found to have “very low” to “low” expansion potential based on our laboratory test results in accordance with ASTM D 4829. However, Salem also encountered soil units with “medium” expansion potential. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 6 5.3 SURFACE WATER AND GROUNDWATER 5.3.1 Surface Water If encountered during the earthwork construction, surface water on this site is the result of precipitation or surface run-off from surrounding sites. Overall drainage in the area is variable, and most commonly directed toward the west-southwest. Provisions for surface drainage will need to be accounted for by the project civil engineer. 5.3.2 Groundwater Groundwater was not encountered in the deepest site boring, Boring B-5, excavated by Salem (2019) to a maximum depth of 50 feet. The GeoTracker database and the California Water Data Library show several groundwater wells located within 1.5 miles from the site, with a depth to groundwater in excess of 100 feet. Perched groundwater or localized seepage can occur due to variations in rainfall, irrigation practices, and other factors not evident at the time of this investigation. 5.4 FAULTING AND SEISMICITY The geologic structure of the entire southern California area is dominated mainly by northwest- trending faults associated with the San Andreas system. The site is in a seismically active region. No active or potentially active fault is known to exist at this site nor is the site situated within an “Alquist-Priolo” Earthquake Fault Zone (Bryant and Hart, 2007; CGS, 1986). The subject property is not located within a State of California Seismic Hazard Zone for earthquake induced liquefaction (CGS, 1997). The subject property is not located within a State of California Seismic Hazard Zone for earthquake induced landsliding. The nearest known active fault to the site is the Elsinore fault- Whittier Section located approximately 7.6 miles to the north. 5.4.1 Seismic Design Parameters The site is located at approximately 33.8097⁰ Latitude and -117.8437⁰ Longitude. Based on the conditions observed in the site excavations and review of regional geologic maps, a Site Class “D” appears to be the appropriate category for the property. Site spectral accelerations (Sa and S1), for 0.2 and 1.0 second periods for a Class “D” site, were determined from the SEAOC/OSHPD web interface that utilizes the USGS web services and retrieves the seismic design data and presents that information in a report format. As noted using the ASCE 7-16 option on the SEAOC/OSHPD website, the values for SM1 and SD1 are reported as “null-See Section 11.4.8 (of ASCE 7-16)”. As noted in ASCE 7-16, Section 11.4.8, a site-specific ground motion procedure is recommended for Site Class D when the value S1 exceeds 0.2. The value S1 for the subject site exceeds 0.2. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 7 For a Site Class “D”, an exception to performing a site-specific ground motion analysis is allowed in ASCE 7-16 where S1 exceeds 0.2 provided the value of the seismic response coefficient, Cs, is conservatively calculated by Eq 12.8-2 of ASCE 7-16 for values of T≤1.5Ts and taken as equal to 1.5 times the value computed in accordance with either Eq. 12.8-3 for TL≥T>1.5Ts or Eq. 12.8-4 for T>TL. Assuming that the Cs value calculated by and used by the structural engineer allows for the exclusion per ASCE 7-16, noted above, then a site-specific ground motion analysis is not required. For this assumption and condition, the following seismic design parameters, based on the 2015 National Earthquake Hazards Reduction Program (NEHRP)/ASCE 7-16, are presented on the following table: SITE SEISMIC PARAMETERS Mapped 0.2 sec Period Spectral Acceleration, Ss 1.426g Mapped 1.0 sec Period Spectral Acceleration, S1 0.507g Site Coefficient for Site Class “D,” Fa 1.0 Site Coefficient for Site Class “D,” Fv 1.793 Maximum Considered Earthquake Spectral Response Acceleration for 0.2 Second, SMS 1.426g Maximum Considered Earthquake Spectral Response Acceleration for 1.0 Second, SM1 0.908g 5% Damped Design Spectral Response Acceleration Parameter at 0.2 Second, SDS 0.951g 5% Damped Design Spectral Response Acceleration Parameter at 1 second, SD1 0.606g Site Modified Peak Ground Acceleration, PGAM 0.658g Seismic Design Category D Final selection of the appropriate seismic design coefficients should be made by the project structural engineer based upon the local practices and ordinances, expected building response and desired level of conservatism. 5.5 LIQUEFACTION AND SEISMICALLY INDUCED SETTLEMENT The project site is not located within an area mapped by the State of California for liquefaction potential. Due to the presence of dense/stiff alluvium and the lack of shallow groundwater, the risk of soil liquefaction at the site is nil. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 8 Loose to medium dense sands tend to densify during strong ground shaking. Based on the blow counts recorded in the deepest site boring (Salem’s boring B-5) and utilizing a peak ground acceleration of 0.66g and a modal magnitude weighted (Mw) seismic event of 7.72, we estimate that the seismically induced settlement of the sandy units at the site is less than 0.5 inches total settlement and less than 0.25-inches differential settlement over a 30-foot span. 5.6 OTHER SEISMIC HAZARDS Evidence of ancient landslides or slope instabilities at this site was not observed during our investigation. Thus, the potential for landslides is considered negligible. The site is located about two miles west of the Santiago Creek Recharge Basin. However, as the project site is located at a higher elevation than the basin, the potential for a seiche is considered negligible. The potential for a tsunami is also nil due to the great distance between the site and the ocean. 6. CONCLUSIONS AND RECOMMENDATIONS 6.1 GENERAL Development of the site appears feasible from a geotechnical viewpoint. The following recommendations should be incorporated into the design and construction phases of development. 6.2 EARTHWORK CONSIDERATIONS Earthwork and grading should be performed in accordance with the applicable grading ordinances of the City of Orange, the 2019 California Building Code (CBC), and recommendations contained in this report. Site grading plans should be reviewed by this office when they become available. Additional recommendations will likely be offered subsequent to review of these plans. 6.2.1 Site Clearing and Preparation Site preparation should start with demolition/razing of existing site improvements and removal of deleterious materials and vegetation. Demolition should include removal of all pavements, floor slabs, foundations, and any other below-grade construction. These materials should be properly disposed of off-site. Voids resulting from site clearing (such as removals of underground utilities, foundations, etc.) should be replaced with engineered fill materials. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 9 6.2.2 Removals Based on the boring data and the field observations, the upper three (3) to fifteen (15) feet of existing site soils or two (2) feet below footing base, whichever is deeper. should be removed in order to provide a homogeneous, dense fill mat for structural support. Deeper removals may be required in some areas to eliminate all undocumented fill and unsuitable alluvium. The bottom of removals should expose competent native alluvial soils which are defined as relatively homogeneous, no visibly porous materials with an in-place density of at least 85 percent of the soil’s maximum dry density as determined per ASTM D 1557. As a minimum, removals should extend down and away from foundation elements at a 1:1 (h:v) projection to the recommended removal depth, or a minimum of five feet laterally. The upper two feet of soil or one foot below pavement subgrade, whichever is deeper, should be removed below asphaltic concrete pavement and Portland cement concrete hardscape areas. Deeper removals may be required in areas containing loose undocumented fills. The horizontal extent of removals should extend at least two feet beyond the edge of the improvements. The bottom of all removals should be scarified to a minimum depth of 12 inches, brought to slightly above the optimum moisture content, and then recompacted to at least 90 percent of the soil’s maximum dry density (ASTM D 1557). The bottoms of removals should be observed by a GeoTek representative prior to scarification. 6.2.3 Engineered Fill The onsite soils are considered suitable for reuse as engineered fill provided they are free from vegetation, roots, and rock/concrete or hard lumps greater than six (6) inches in maximum dimension. Concrete generated from the demolition of existing site improvements may be incorporated into site fills provided the following guidelines are implemented: 1) concrete should be free of rebar or other deleterious materials and should be broken down to a maximum dimension of six (6) inches; 2) concrete should not be placed within three (3) feet of finish grade in the building pad areas or within one (1) foot of subgrade elevations in the street/drive areas; 3) concrete should be distributed in the fill and should not be “nested” or placed in concentrated pockets. The undercut areas should be brought to final pad elevations with fill materials that are placed and compacted in general accordance with minimum project standards. Fill materials should be placed at or above optimum moisture content and should be compacted to a minimum relative compaction of 90 percent as determined by ASTM Test Method D 1557. Additional recommendations pertaining to fill placement are presented in Appendix E. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 10 6.2.4 Excavation Characteristics Excavation in the onsite soil materials is expected to be easy using heavy-duty grading equipment in good operating conditions. All temporary excavations for grading purposes and installation of underground utilities should be constructed in accordance with local and Cal-OSHA guidelines. Temporary excavations within the onsite materials should be stable at 1:1 (h:v) inclinations for cuts less than ten (10) feet in height. 6.2.5 Shrinkage and Subsidence Several factors will impact earthwork balancing on the site, including shrinkage, subsidence, trench spoil from utilities and footing excavations, as well as the accuracy of topography. Shrinkage, bulking, and subsidence are primarily dependent upon the degree of compactive effort achieved during construction. For planning purposes, a shrinkage factor of 5 to 10 percent for both the existing fills and upper alluvium may be considered. Site balance areas should be available in order to adjust project grades, depending on actual field conditions at the conclusion of site earthwork construction. Bulking is not considered to be a significant factor with the underlying materials within the vicinity of the anticipated construction. Subsidence on the order of up to 0.1-foot could occur. 6.2.6 Trench Excavations and Backfill Temporary excavations within the onsite materials should be stable at 1:1 (h:v) inclinations for short durations during construction, and where cuts do not exceed ten (10) feet in height. Temporary cuts to a maximum height of four (4) feet can be excavated vertically, but local sloughing and/or failure could occur due to the granular nature of some of the onsite units. Increased caution should be applied when working near or within any excavations at this site. Trench excavations should conform to Cal-OSHA regulations. The contractor should have a competent person, per OSHA requirements, on site during construction to observe conditions and to make the appropriate recommendations. Utility trench backfill should be compacted to at least 90 percent relative compaction (as determined per ASTM D 1557). Under-slab trenches should also be compacted to project specifications. Where applicable, based on jurisdictional requirements, the top 12 inches of backfill below subgrade for road pavements should be compacted to at least 95 percent relative compaction. Much of the onsite materials may not be suitable for use as bedding material but should be suitable as backfill provided particles larger than six (6) ± inches are removed. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 11 Compaction should be achieved with a mechanical compaction device. Ponding or jetting of trench backfill is not recommended. If backfill soils have dried out, they should be thoroughly moisture conditioned prior to placement in trenches. 6.3 DESIGN RECOMMENDATIONS 6.3.1 Foundation Design Criteria The site soils are anticipated to have a expansion potential ranging from “very low” to “medium” when tested in accordance with ASTM D 4829. Additional testing of the soils should be performed during construction to evaluate the as-graded conditions. Additional recommendations may be necessary based on the as-graded soils conditions. A summary of GeoTek’s preliminary conventional foundation design recommendations is presented in the table below: Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 12 MINIMUM DESIGN REQUIREMENTS FOR CONVENTIONAL REINFORCED SHALLOW FOUNDATIONS Design Parameter “Very Low” Expansion Potential (0≤EI≤20) “Low” Expansion Potential (20≤EI≤50) “Medium” Expansion Potential (51≤EI≤90) Foundation Depth or Minimum Perimeter Beam Depth (inches below lowest adjacent grade) One-Story – 12 Two-Story – 12 Three-Story - 18 One-Story – 12 Two-Story – 12 Three-Story - 18 One-Story – 18 Two-Story – 18 Three-Story - 24 Minimum Foundation Width (Inches)* One-Story – 12 Two-Story – 12 Three-Story – 15 One-Story – 12 Two-Story – 12 Three-Story – 15 One-Story – 12 Two-Story – 12 Three-Story – 15 Minimum Slab Thickness (actual) 4 inches (actual) 4 inches (actual) 4 inches (actual) Minimum Slab Reinforcing 6” x 6” – W1.4/W1.4 welded wire fabric placed in middle of slab 6” x 6” – W2.9/W2.9 welded wire fabric or No. 3 reinforcing bars at 24 inches on center each way placed in middle of slab No. 3 reinforcing bars at 18 inches on center each way placed in middle of slab Minimum Footing Reinforcement Two No. 4 Reinforcing Bars, one top and one bottom Two No. 4 Reinforcing Bars, one top and one bottom Four No. 4 Reinforcing Bars, Two top and two bottom Effective Plasticity Index** NA 15 20 Presaturation of Subgrade Soil (Percent of Optimum/Depth in inches) Minimum 100% of the optimum moisture content to a depth of at least 12 inches prior to placing concrete Minimum 110% of the optimum moisture content to a depth of at least 12 inches prior to placing concrete Minimum 120% of the optimum moisture content to a depth of at least 18 inches prior to placing concrete *Code minimums per Table 1809.7 of the 2019 CBC should be complied with. **Effective Plasticity Index should be verified at the completion of the rough grading It should be noted that the criteria provided are based on soil support characteristics only. The structural engineer should design the slab and beam/footing reinforcement based on actual loading conditions. An allowable bearing capacity of 2,000 pounds per square foot (psf) may be used for design of continuous and perimeter footings at least 12 inches deep and 12 inches wide, and pad footings 24 inches square and 12 inches deep. This allowable soil bearing capacity may be increased by 400 psf for each additional foot of footing depth and 200 psf for each additional foot of footing width to a maximum value of 3,000 psf. An increase of one-third may be applied when considering short-term live loads (e.g., seismic and wind loads). Structural foundations should be designed in accordance with the 2019 CBC, and to withstand a total static settlement of one-inch and a differential static settlement of one-half of the total Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 13 settlement over a horizontal distance of 30 feet. A total seismically induced settlement of approximately 0.5 inches and a differential seismically induced settlement of about 0.25 inches over a horizontal distance of 30 feet are also anticipated. The passive earth pressure may be computed as an equivalent fluid having a density of 230 psf per foot of depth, to a maximum earth pressure of 2,000 psf for footings founded on engineered fill. A coefficient of friction between soil and concrete of 0.3 may be used with dead load forces. The passive pressure and frictional resistance can be combined without reduction. The upper one foot of soil should be ignored in the passive pressure calculations unless the surface is covered with concrete or asphalt. The passive pressure and frictional resistance may be combined without reduction. A grade beam, a minimum of 12 inches wide and 12 inches deep, should be utilized across large entrances. The base of the grade beam should be at the same elevation as the bottom of the adjoining footings. Alternatively, the buildings may rest on post-tensioned slabs. If this foundation option is selected, GeoTek should be contacted to provide geotechnical design parameters. A moisture and vapor retarding system should be placed below slabs-on-grade where moisture migration through the slab is undesirable. Guidelines for these systems are provided in the 2019 California Green Building Standards Code (CALGreen) Section 4.505.2, the 2019 CBC Section 1907.1, ACI 360R-10, and ACI 302.2R-06. It should be realized that the effectiveness of the vapor retarding membrane can be adversely impacted as the result of construction related punctures (e.g. stake penetrations, tears, punctures from walking on the aggregate layer, etc.). These occurrences should be limited as much as possible during construction. Thicker membranes are generally more resistant to accidental puncture than thinner ones. Products specifically designed for use as moisture/vapor retarders may also be more puncture resistant. It is GeoTek’s opinion that a minimum ten mil thick membrane with joints properly overlapped and sealed should be considered, unless otherwise specified by the slab design professional. Moisture and vapor retarding systems are intended to provide a certain level of resistance to vapor and moisture transmission through the concrete, but do not eliminate it. The acceptable level of moisture transmission through the slab is to a large extent based on the type of flooring used and atmospheric conditions. Ultimately, the vapor retarding system should be comprised of suitable elements to limit migration of water and reduce transmission of water vapor through the slab to acceptable levels. The selected elements should have suitable properties (i.e. thickness, composition, strength, and Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 14 permeance) to achieve the desired performance level. Consideration should be given to consulting with an individual possessing specific expertise in this area for additional evaluation. 6.3.2 Miscellaneous Foundation Recommendations  To minimize moisture penetration beneath the slab on grade areas, utility trenches should be backfilled with engineered fill, lean concrete, or concrete slurry where they intercept the perimeter footing or thickened slab edge.  Soils from the footing excavations should not be placed in the slab-on-grade areas unless properly compacted and tested. The excavations should be free of loose/sloughed materials and be neatly trimmed at the time of concrete placement.  Under-slab utility trenches should be compacted to project specifications. Compaction should be achieved with a mechanical compaction device. If backfill soils have dried out, they should be thoroughly moisture conditioned prior to placement in trenches. 6.3.3 Foundation Set Backs Foundations should comply with the following setbacks. Improvements not conforming to these setbacks are subject to the increased likelihood of excessive lateral movements and/or differential settlements. If large enough, these movements can compromise the integrity of the improvements. The following recommendations are presented:  The outside bottom edge of all footings should be set back a minimum of H/2 (where H is the slope height) from the face of any ascending slope. The setback should be at least five (5) feet and need not to exceed fifteen (15) feet. Where a retaining wall is constructed at the toe of the slope, the height of the slope should be measured from top of the wall to the top of the slope.  The outside bottom edge of all footings should be set back a minimum of H/3 from the face of any descending slope. The setback should be at least seven (7) feet and need not exceed forty (40) feet.  The bottom of all footings for structures near retaining walls should be deepened so as to extend below a 1:1 (h:v) projection upward from the bottom inside edge of the wall foundation.  The bottom of any planned foundations for structures should be deepened so as to extend below a 1:1 (h:v) projection upward from the bottom of the nearest excavation. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 15 6.3.4 Retaining Wall Design and Construction 6.3.4.1 General Design Criteria Recommendations presented in this report apply to typical masonry or concrete walls retaining up to six feet of soils. Additional review and recommendations should be requested for higher walls. These are typical design criteria and are not intended to supersede the design by the structural engineer. Retaining wall foundations should be embedded a minimum of 12 inches into “very low” and “low” expansive soils and a minimum of 18 inches into “medium” expansive soils. Foundations should be designed in accordance with Section 6.3.1 of this report. Structural needs may govern and should be evaluated by the project structural engineer. All earth retention structure plans, as applicable, should be reviewed by this office prior to finalization. The seismic design parameters as discussed in this report remain applicable to all proposed earth retention structures at this site and should be properly incorporated into the design and construction of the structures. Earthwork considerations, site clearing and remedial earthwork for all earth retention structures should meet the requirements of this report, unless specifically provided otherwise, or more stringent requirements or recommendations are made by the designer. The backfill material placement for all earth retention structures should meet the requirement of Section 6.3.4.4 in this report. In general, cantilever earth retention structures, which are designed to yield at least 0.001H, where H is equal to the height of the earth retention structure to the base of its footing, may be designed using the active condition. Rigid earth retention structures (including but not limited to rigid walls, and walls braced at top, such as typical basement walls) should be designed using the at-rest condition. In addition to the design lateral forces due to retained earth, surcharges due to improvements, such as an adjacent building or traffic loading, should be considered in the design of the earth retention structures. Loads applied within a 1:1 (h:v) projection from the surcharge on the stem and footing of the earth retention structure should be considered in the design. Final selection of the appropriate design parameters should be made by the designer of the earth retention structures. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 16 6.3.4.2 Cantilevered Walls The recommendations presented below are for cantilevered walls retaining up to six feet of soils. Active earth pressure may be used for retaining wall design, provided the top of the wall is not restrained from minor deflections. An equivalent fluid pressure approach may be used to compute the horizontal pressure against the wall. Appropriate fluid unit weights are given below for specific slope gradients of the retained material. These do not include other superimposed loading conditions such as traffic, structures, or adverse geologic conditions. ACTIVE EARTH PRESSURES Surface Slope of Retained Materials (h:v) Equivalent Fluid Pressure (pcf) Selected Native Backfill* Equivalent Fluid Pressure (pcf) Import Granular Backfill** Level 45 36 2:1 81 53 *The design pressures assume the native backfill material has an expansion index less than or equal to 50 and a friction angle of about 28 degrees or better. Backfill zone includes area between the back of the wall and footing to a plane (1:1 h:v) up from the bottom of the wall foundation to the ground surface. **The design pressures assume that import granular backfill material has an expansion index less than or equal to 20 and a friction angle of at least 34 degrees. Backfill zone includes area between the back of the wall and footing to a plane (1:1 h:v) up from the bottom of the wall foundation to the ground surface. 6.3.4.3 Restrained Retaining Walls Retaining walls that will be restrained prior to placing and compacting backfill material, or that have reentrant or male corners, should be designed for an at-rest equivalent fluid pressure of 66 pcf, plus any applicable surcharge loading, for native backfill and level back slope condition. For imported granular backfill, an at-rest equivalent fluid pressure of 57 pcf should be utilized. For areas of male or reentrant corners, the restrained wall design should extend a minimum distance of twice the height of the wall laterally from the corner, or a distance otherwise determined by the project structural engineer. 6.3.4.4 Retaining Wall Backfill and Drainage Retaining wall backfill should be free of deleterious and/or oversized materials and should have properties indicated in Section 6.3.4.2. Retaining walls should be provided with an adequate pipe and gravel back drain system to help prevent buildup of hydrostatic pressures. Backdrains should consist of a four-inch diameter perforated collector pipe (Schedule 40, SDR 35, or approved equivalent) embedded in a minimum of one-cubic foot per linear foot of ¾- to 1-inch clean crushed rock or an approved equivalent, wrapped in filter fabric (Mirafi 140N or an approved Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 17 equivalent). The drain system should be connected to a suitable outlet. Waterproofing of site walls should be performed where moisture migration through the wall is undesirable. Retaining wall backfill should be placed in lifts no greater than eight inches in thickness and compacted to a minimum of 90 percent relative compaction in accordance with ASTM Test Method D 1557. The wall backfill should also include a minimum one-foot wide section of ¾- to 1-inch clean crushed rock (or an approved equivalent). The rock should be placed immediately adjacent to the back of the wall and extend up from a back drain to within approximately 24 inches of the finish grade. The rock should be separated from the earth with filter fabric. The upper 24 inches should consist of compacted on-site soil. As an alternative to the drain rock and fabric, Miradrain 2000, or approved equivalent, may be used behind the retaining wall. The Miradrain 2000 should extend from the base of the wall to within two feet of the ground surface. The subdrain should be placed at the base of the wall in direct contact with the Miradrain 2000. The presence of other materials might necessitate revision to the parameters provided and modification of the wall designs. Proper surface drainage needs to be provided and maintained. 6.3.4.5 Other Design Considerations  Wall design should consider the additional surcharge loads from superjacent slopes and/or footings, where appropriate.  No backfill should be placed against concrete until minimum design strengths are evident by compression tests of cylinders.  The retaining wall footing excavations, backcuts, and backfill materials should be approved the project geotechnical engineer or their authorized representative. 6.3.5 Pavement Design Considerations Pavement design for proposed on-site parking and drive areas was conducted per Caltrans Highway Design Manual guidelines for flexible pavements and the Portland Cement Association for rigid pavements. Based on an assumed design R-value of 20 and for Traffic Indexes (TIs) of 5.0 for car parking areas and 6.0 for drive areas for light traffic with occasional truck traffic, the following preliminary sections were calculated: Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 18 PRELIMINARY PAVEMENT SECTIONS Traffic Index Thickness of Flexible Pavement Section Thickness of Rigid Pavement Section 5.0 3” AC / 7.5” AB -- 6.0 4” AC / 8.5” AB 6.5” PCC/ 4” AB *AC = Asphalt Concrete, AB = Aggregate Base, PCC = Portland Cement Concrete with a f’c > 3,500 psi. The TIs used in our pavement design are considered reasonable values for the proposed pavement areas and should provide a pavement life of approximately 20 years with a normal amount of flexible pavement maintenance. Irrigation adjacent to pavements, without a deep curb or other cutoff to separate landscaping from the paving may result in premature pavement failure. Traffic parameters used for design were selected based upon engineering judgment and not upon information furnished to us such as an equivalent wheel load analysis or a traffic study. No structural reinforcement of the concrete pavements is required. However, temperature and shrinkage control reinforcement should be provided. This reinforcement should consist of No, 4 rebars on 24-inch centers, each way, or equivalent. The reinforcement should be placed at mid-height to the concrete pavement. Also, the concrete pavement should be provided with proper joints to help control cracking. All materials and methods of construction should also conform to the requirements of the City of Orange. These pavement sections should be considered preliminary until reviewed and approved by the City. The recommended pavement sections provided are intended as a minimum guideline and final selection of pavement cross section parameters should be made by the project civil engineer, based upon the local laws and ordinates, expected subgrade and pavement response, and desired level of conservatism. If thinner or highly variable pavement sections are constructed, increased maintenance and repair could be expected. Final pavement design should be checked by testing of soils exposed at subgrade (the upper one foot) after final grading has been completed. Asphalt concrete and aggregate base should conform to current Caltrans Standard Specifications Section 39 and 26-1.02, respectively. As an alternative, asphalt concrete can conform to Section 203-6 of the current Standard Specifications for Public Work (Green Book). Crushed aggregate base or crushed miscellaneous base can conform to Section 200-2.2 and 200-2.4 of the Green Book, respectively. Pavement base should be compacted to at least 95 percent of the ASTM D1557 laboratory maximum dry density (modified proctor). All pavement installation, including preparation and compaction of subgrade, compaction of base material, placement and rolling of asphaltic concrete, should be done in accordance with the City of Orange specifications, and under the observation and testing of GeoTek and a City Inspector Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 19 where required. Jurisdictional minimum compaction requirements in excess of the aforementioned minimums may govern. Deleterious material, excessive wet or dry pockets, oversized rock fragments, and other unsuitable yielding materials encountered during grading should be removed. Once existing compacted fill are brought to the proposed pavement subgrade elevations, the subgrade should be proof-rolled in order to check for a uniform and unyielding surface. The upper 12 inches of pavement subgrade soils should be scarified, moisture conditioned at or near optimum moisture content, and recompacted to at least 95 percent of the laboratory maximum dry density (ASTM D1557). If loose or yielding materials are encountered during construction, additional evaluation of these areas should be carried out by GeoTek. All pavement section changes should be properly transitioned. 6.3.6 Soil Corrosivity The soil resistivity was tested in the laboratory on two samples collected during our field exploration. The results of the testing (2,750 and 2,814 ohm-cm) indicate that the soil samples are “highly corrosive” to buried ferrous metals, based on the guidelines provided in Corrosion Basics: An Introduction (Roberge, 2005). Consideration should be given to consulting with a corrosion engineer. 6.3.7 Soil Sulfate Content The sulfate content was determined in the laboratory for two soil samples obtained during our field exploration. The results (0.0027 and 0.0103 percent) indicate that the water-soluble sulfate range is less than 0.1 percent by weight which is considered “not applicable” (i.e. negligible) as per Table 4.2.1 of ACI 318. Based upon the test results, no special concrete mix design is required by Code for sulfate attack resistance. Additional testing of soils collected near finish grade should be performed subsequent to site grading. 6.3.8 Import Soils Import soils should have a “very low” expansion potential. GeoTek also recommends that, as a minimum, proposed import soils be tested for soluble sulfate content. GeoTek should be notified a minimum of 72 hours of potential import sources so that appropriate sampling and laboratory testing can be performed. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 20 6.3.9 Concrete Flatwork 6.3.9.1 Exterior Concrete Slabs, Sidewalks, and Driveways Exterior concrete slabs, sidewalks, and driveways should be designed using a four-inch minimum thickness. No specific reinforcement is required due to the non-structural nature. However, the use of some reinforcement should be considered. Some shrinkage and cracking of the concrete should be anticipated as a result of typical mix designs and curing practices commonly utilized in residential construction. Sidewalks and driveways may be under the jurisdiction of the governing agency. If so, jurisdictional design and construction criteria would apply, if more restrictive than the recommendations presented herein. Subgrade soils should be pre-moistened prior to placing concrete. The subgrade with “very low” expansion potential should be pre-saturated to a minimum of 100 percent of optimum moisture content to a depth of at least 12 inches. Soils with “low” and “medium” expansion potentials should be pre-saturated to a minimum of 110 and 120 percent of optimum moisture content, respectively. Presaturation depth should be at least 12 inches. All concrete installation, including preparation and compaction of subgrade, should be done in accordance with the City of Orange specifications, and under the observation and testing of GeoTek and a City Inspector, if necessary. 6.3.9.2 Concrete Performance Concrete cracks should be expected. These cracks can vary from sizes that are essentially unnoticeable to more than 1/8 inch in width. Most cracks in concrete, while unsightly, do not significantly impact long-term performance. While it is possible to take measures (proper concrete mix, placement, curing, control joints, etc.) to reduce the extent and size of cracks that occur, some cracking will occur despite the best efforts to minimize it. Concrete can also undergo chemical processes that are dependent on a wide range of variables, which are difficult, at best, to control. Concrete, while seemingly a stable material, is also subject to internal expansion and contraction due to external changes over time. One of the simplest means to control cracking is to provide weakened control joints for cracking to occur along. These do not prevent cracks from developing; they simply provide a relief point for the stresses that develop. These joints are a widely accepted means to control cracks but are not always effective. Control joints are more effective the more closely spaced they are. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 21 GeoTek suggests that control joints be placed in two directions and located a distance apart roughly equal to 24 to 36 times the slab thickness. Exterior concrete flatwork (patios, walkways, driveways, etc.) is often some of the most visible aspects of site development. They are typically given the least level of quality control, being considered “non-structural” components. We suggest that the same standards of care be applied to these features as to the structure itself. 6.4 POST CONSTRUCTION CONSIDERATIONS 6.4.1 Landscape Maintenance and Planting Water has been shown to weaken the inherent strength of soil, and slope stability is significantly reduced by overly wet conditions. Positive surface drainage away from graded slopes should be maintained and only the amount of irrigation necessary to sustain plant life should be provided for planted slopes. Controlling surface drainage and runoff and maintaining a suitable vegetation cover can minimize erosion. Plants selected for landscaping should be lightweight, deep-rooted types that require little water and are capable of surviving the prevailing climate. Overwatering should be avoided. The soils should be maintained in a solid to semi-solid state as defined by the materials Atterberg Limits. Care should be taken when adding soil amendments to avoid excessive watering. Leaching as a method of soil preparation prior to planting is not recommended. An abatement program to control ground-burrowing rodents should be implemented and maintained. This is critical as burrowing rodents can decreased the long-term performance of slopes. It is common for planting to be placed adjacent to structures in planter or lawn areas. This will result in the introduction of water into the ground adjacent to the foundation. This type of landscaping should be avoided. If used, then extreme care should be exercised with regard to the irrigation and drainage in these areas. 6.4.2 Drainage The need to maintain proper surface drainage and subsurface systems cannot be overly emphasized. Positive site drainage should be maintained at all times. Drainage should not flow uncontrolled down any descending slope. Water should be directed away from foundations and not allowed to pond or seep into the ground. Pad drainage should be directed toward approved area(s) and not be blocked by other improvements. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 22 It is the owner’s responsibility to maintain and clean drainage devices on or contiguous to their lot. In order to be effective, maintenance should be conducted on a regular and routine schedule and necessary corrections made prior to each rainy season. 6.5 PLAN REVIEW AND CONSTRUCTION OBSERVATIONS We recommend that site grading plans, pool plans, retaining wall plans, foundation plans, and relevant project specifications be reviewed by this office prior to construction to check for conformance with the recommendations of this report. We also recommend that GeoTek representatives be present during site grading and foundation construction to check for proper implementation of the geotechnical recommendations. The owner/developer should verify that GeoTek representatives perform at least the following duties:  Observe site clearing and grubbing operations for proper removal of unsuitable materials.  Observe and test bottom of removals prior to fill placement.  Evaluate the suitability of onsite and import materials for fill placement and collect soil samples for laboratory testing where necessary.  Observe the fill for uniformity during placement, including utility trenches.  Perform field density testing of the fill materials.  Observe and probe foundation excavations to confirm suitability of bearing materials. If requested, a construction observation and compaction report can be provided by GeoTek, which can comply with the requirements of the governmental agencies having jurisdiction over the project. We recommend that these agencies be notified prior to commencement of construction so that necessary grading permits can be obtained. 7. INTENT It is the intent of this report to aid in the design and construction of the proposed development. Implementation of the advice presented in this report is intended to reduce risk associated with construction projects. The professional opinions and geotechnical advice contained in this report are not intended to imply total performance of the project or guarantee that unusual or variable conditions will not be discovered during or after construction. The scope of our evaluation is limited to the boundaries of the subject site. This review does not and should in no way be construed to encompass any areas beyond the specific area of the proposed construction as indicated to us by the client. Further, no evaluation of any existing site improvements is included. The scope is based on our understanding of the project and the Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 23 client’s needs, our fee estimate (P-04010622-CR) dated April 20, 2022 and geotechnical engineering standards normally used on similar projects in this region. 8. LIMITATIONS The materials observed on the project site appear to be representative of the area; however, soil materials vary in character between excavations or conditions exposed during site construction.

Katella Avenue, Orange, California Page B-1 A - FIELD TESTING AND SAMPLING PROCEDURES The Modified Split-Barrel Sampler (Ring) The ring sampler is driven into the ground in accordance with ASTM Test Method D 3550. The sampler, with an external diameter of 3.0 inches, is lined with 1-inch long, thin brass rings with inside diameters of approximately 2.4 inches. The sampler is typically driven into the ground 12 or 18 inches with a 140- pound hammer free falling from a height of 30 inches. Blow counts are recorded for every 6 inches of penetration as indicated on the logs of borings. The samples are removed from the sample barrel in the brass rings, sealed, and transported to the laboratory for testing. Bulk Samples (Large) These samples are normally large bags of earth materials over 20 pounds in weight collected from the field by means of hand digging or exploratory cuttings. Bulk Samples (Small) These are plastic bag samples which are normally airtight and contain less than five pounds in weight of earth materials collected from the field by means of hand digging or exploratory cuttings. These samples are primarily used for determining natural moisture content and classification indices.

Katella Avenue, Orange, California Page C-1 SUMMARY OF LABORATORY TESTING Classification Soils were classified visually in general accordance with the Unified Soil Classification System (ASTM Test Method D 2487). The soil classifications are shown on the logs of exploratory borings in Appendix B. Collapse Collapse tests were conducted in accordance with ASTM D4546. The results of these tests are presented herewith. Expansion Index The expansion potential of the soils was determined by performing expansion index tests on two representative soil samples from the site in general accordance with ASTM D 4829. The results of these tests are presented herewith. In Situ Moisture Content and Unit Weight The field moisture content was measured in the laboratory on selected samples collected during the field investigation. The field moisture content is determined as a percentage of the dry unit weight. The dry density was measured in the laboratory on selected ring samples. The results are shown on the logs of exploratory borings in Appendix B. Moisture-Density Relationship Laboratory testing was performed on two representative soil samples collected during the subsurface exploration. The laboratory maximum dry density and optimum moisture content for the soil type was determined in general accordance with test method ASTM Test Procedure D 1557. The results are presented herewith. Sulfate Content, Resistivity and Chloride Content Testing to determine the water-soluble sulfate content, minimum resistivity, and chloride concentration in selected soil samples was performed by others. The results are included herewith.

Katella Avenue, Orange, California Project No. 3193-CR GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 1 901 E. Katella Avenue, Orange, California Project No. 3193-CR GENERAL GRADING GUIDELINES Guidelines presented herein are intended to address general construction procedures for earthwork construction. Specific situations and conditions often arise which cannot reasonably be discussed in general guidelines, when anticipated these are discussed in the text of the report. Often unanticipated conditions are encountered which may necessitate modification or changes to these guidelines. It is our hope that these will assist the contractor to more efficiently complete the project by providing a reasonable understanding of the procedures that would be expected during earthwork and the testing and observation used to evaluate those procedures. General Grading should be performed to at least the minimum requirements of governing agencies, Chapters 18 and 33 of the California Building Code, CBC (2019) and the guidelines presented below. Preconstruction Meeting A preconstruction meeting should be held prior to site earthwork. Any questions the contractor has regarding our recommendations, general site conditions, apparent discrepancies between reported and actual conditions and/or differences in procedures the contractor intends to use should be brought up at that meeting. The contractor (including the main onsite representative) should review our report and these guidelines in advance of the meeting. Any comments the contractor may have regarding these guidelines should be brought up at that meeting. Grading Observation and Testing 1. Observation of the fill placement should be provided by our representative during grading. Verbal communication during the course of each day will be used to inform the contractor of test results. The contractor should receive a copy of the "Daily Field Report" indicating results of field density tests that day. If our representative does not provide the contractor with these reports, our office should be notified. 2. Testing and observation procedures are, by their nature, specific to the work or area observed and location of the tests taken, variability may occur in other locations. The contractor is responsible for the uniformity of the grading operations; our observations and test results are intended to evaluate the contractor’s overall level of efforts during grading. The contractor’s personnel are the only individuals participating in all aspect of site work. Compaction testing and observation should not be considered as relieving the contractor’s responsibility to properly compact the fill. 3. Cleanouts, processed ground to receive fill, key excavations, and subdrains should be observed by our representative prior to placing any fill. It will be the contractor's responsibility to notify our representative or office when such areas are ready for observation. 4. Density tests may be made on the surface material to receive fill, as considered warranted by this firm. 5. In general, density tests would be made at maximum intervals of two feet of fill height or every 1,000 cubic yards of fill placed. Criteria will vary depending on soil conditions and size of the fill. More frequent testing may be performed. In any case, an adequate number of field density tests should be made to evaluate the required compaction and moisture content is generally being obtained. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 2 901 E. Katella Avenue, Orange, California Project No. 3193-CR 6. Laboratory testing to support field test procedures will be performed, as considered warranted, based on conditions encountered (e.g. change of material sources, types, etc.) Every effort will be made to process samples in the laboratory as quickly as possible and in progress construction projects are our first priority. However, laboratory workloads may cause in delays and some soils may require a minimum of 48 to 72 hours to complete test procedures. Whenever possible, our representative(s) should be informed in advance of operational changes that might result in different source areas for materials. 7. Procedures for testing of fill slopes are as follows: a) Density tests should be taken periodically during grading on the flat surface of the fill, three to five feet horizontally from the face of the slope. b) If a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. 8. Finish grade testing of slopes and pad surfaces should be performed after construction is complete. Site Clearing 1. All vegetation, and other deleterious materials, should be removed from the site. If material is not immediately removed from the site it should be stockpiled in a designated area(s) well outside of all current work areas and delineated with flagging or other means. Site clearing should be performed in advance of any grading in a specific area. 2. Efforts should be made by the contractor to remove all organic or other deleterious material from the fill, as even the most diligent efforts may result in the incorporation of some materials. This is especially important when grading is occurring near the natural grade. All equipment operators should be aware of these efforts. Laborers may be required as root pickers. 3. Nonorganic debris or concrete may be placed in deeper fill areas provided the procedures used are observed and found acceptable by our representative. Treatment of Existing Ground 1. Following site clearing, all surficial deposits of alluvium and colluvium as well as weathered or creep effected bedrock, should be removed unless otherwise specifically indicated in the text of this report. 2. In some cases, removal may be recommended to a specified depth (e.g. flat sites where partial alluvial removals may be sufficient). The contractor should not exceed these depths unless directed otherwise by our representative. 3. Groundwater existing in alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 4. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. 5. Exploratory back hoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Fill Placement 1. Unless otherwise indicated, all site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see text of report). GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 3 901 E. Katella Avenue, Orange, California Project No. 3193-CR 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts six (6) to eight (8) inches in compacted thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a nearly horizontal plane, unless otherwise found acceptable by our representative. 3. If the moisture content or relative density varies from that recommended by this firm, the contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be at or above optimum moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. The ability of the contractor to obtain the proper moisture content will control production rates. b) Each six-inch layer should be compacted to at least 90 percent of the maximum dry density in compliance with the testing method specified by the controlling governmental agency. In most cases, the testing method is ASTM Test Designation D 1557. 4. Rock fragments less than eight inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is observed by, and acceptable to, our representative. 5. Rocks exceeding eight (8) inches in diameter should be taken off site, broken into smaller fragments, or placed in accordance with recommendations of this firm in areas designated suitable for rock disposal. On projects where significant large quantities of oversized materials are anticipated, alternate guidelines for placement may be included. If significant oversize materials are encountered during construction, these guidelines should be requested. 6. In clay soil, dry or large chunks or blocks are common. If in excess of eight (8) inches minimum dimension, then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break up blocks. When dry, they should be moisture conditioned to provide a uniform condition with the surrounding fill. Slope Construction 1. The contractor should obtain a minimum relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. 2. Slopes trimmed to the compacted core should be overbuilt by at least three (3) feet with compaction efforts out to the edge of the false slope. Failure to properly compact the outer edge results in trimming not exposing the compacted core and additional compaction after trimming may be necessary. 3. If fill slopes are built "at grade" using direct compaction methods, then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled or otherwise compacted at approximately every 4 feet vertically as the slope is built. 4. Corners and bends in slopes should have special attention during construction as these are the most difficult areas to obtain proper compaction. 5. Cut slopes should be cut to the finished surface. Excessive undercutting and smoothing of the face with fill may necessitate stabilization. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 4 901 E. Katella Avenue, Orange, California Project No. 3193-CR UTILITY TRENCH CONSTRUCTION AND BACKFILL Utility trench excavation and backfill is the contractors responsibility. The geotechnical consultant typically provides periodic observation and testing of these operations. While efforts are made to make sufficient observations and tests to verify that the contractors’ methods and procedures are adequate to achieve proper compaction, it is typically impractical to observe all backfill procedures. As such, it is critical that the contractor use consistent backfill procedures. Compaction methods vary for trench compaction and experience indicates many methods can be successful. However, procedures that “worked” on previous projects may or may not prove effective on a given site. The contractor(s) should outline the procedures proposed, so that we may discuss them prior to construction. We will offer comments based on our knowledge of site conditions and experience. 1. Utility trench backfill in slopes, structural areas, in streets and beneath flat work or hardscape should be brought to at least optimum moisture and compacted to at least 90 percent of the laboratory standard. Soil should be moisture conditioned prior to placing in the trench. 2. Flooding and jetting are not typically recommended or acceptable for native soils. Flooding or jetting may be used with select sand having a Sand Equivalent (SE) of 30 or higher. This is typically limited to the following uses: a) shallow (12 + inches) under slab interior trenches and, b) as bedding in pipe zone. The water should be allowed to dissipate prior to pouring slabs or completing trench compaction. 3. Care should be taken not to place soils at high moisture content within the upper three feet of the trench backfill in street areas, as overly wet soils may impact subgrade preparation. Moisture may be reduced to 2% below optimum moisture in areas to be paved within the upper three feet below sub grade. 4. Sand backfill should not be allowed in exterior trenches adjacent to and within an area extending below a 1:1 projection from the outside bottom edge of a footing, unless it is similar to the surrounding soil. 5. Trench compaction testing is generally at the discretion of the geotechnical consultant. Testing frequency will be based on trench depth and the contractors procedures. A probing rod would be used to assess the consistency of compaction between tested areas and untested areas. If zones are found that are considered less compact than other areas, this would be brought to the contractors attention. JOB SAFETY General Personnel safety is a primary concern on all job sites. The following summaries are safety considerations for use by all our employees on multi-employer construction sites. On ground personnel are at highest risk of injury and possible fatality on grading construction projects. The company recognizes that construction activities will vary on each site and that job site safety is the contractor's responsibility. However, it is, imperative that all personnel be safety conscious to avoid accidents and potential injury. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 5 901 E. Katella Avenue, Orange, California Project No. 3193-CR In an effort to minimize risks associated with geotechnical testing and observation, the following precautions are to be implemented for the safety of our field personnel on grading and construction projects. 1. Safety Meetings: Our field personnel are directed to attend the contractor's regularly scheduled safety meetings. 2. Safety Vests: Safety vests are provided for and are to be worn by our personnel while on the job site. 3. Safety Flags: Safety flags are provided to our field technicians; one is to be affixed to the vehicle when on site, the other is to be placed atop the spoil pile on all test pits. In the event that the contractor's representative observes any of our personnel not following the above, we request that it be brought to the attention of our office. Test Pits Location, Orientation and Clearance The technician is responsible for selecting test pit locations. The primary concern is the technician's safety. However, it is necessary to take sufficient tests at various locations to obtain a representative sampling of the fill. As such, efforts will be made to coordinate locations with the grading contractors authorized representatives (e.g. dump man, operator, supervisor, grade checker, etc.), and to select locations following or behind the established traffic pattern, preferably outside of current traffic. The contractors authorized representative should direct excavation of the pit and safety during the test period. Again, safety is the paramount concern. Test pits should be excavated so that the spoil pile is placed away from oncoming traffic. The technician's vehicle is to be placed next to the test pit, opposite the spoil pile. This necessitates that the fill be maintained in a drivable condition. Alternatively, the contractor may opt to park a piece of equipment in front of test pits, particularly in small fill areas or those with limited access. A zone of non-encroachment should be established for all test pits (see diagram below). No grading equipment should enter this zone during the test procedure. The zone should extend outward to the sides approximately 50 feet from the center of the test pit and 100 feet in the direction of traffic flow. This zone is established both for safety and to avoid excessive ground vibration, which typically decreases test results. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 6 901 E.

The contractor's representative should effectively keep all equipment at a safe operation distance (e.g. 50 feet) away from the slope during testing. The technician is directed to withdraw from the active portion of the fill as soon as possible following testing. The technician's vehicle should be parked at the perimeter of the fill in a highly visible location. Trench Safety It is the contractor's responsibility to provide safe access into trenches where compaction testing is needed. Trenches for all utilities should be excavated in accordance with CAL-OSHA and any other applicable safety standards. Safe conditions will be required to enable compaction testing of the trench backfill. All utility trench excavations in excess of 5 feet deep, which a person enters, are to be shored or laid back. Trench access should be provided in accordance with OSHA standards. Our personnel are directed not to enter any trench by being lowered or "riding down" on the equipment. Our personnel are directed not to enter any excavation which; 1. is 5 feet or deeper unless shored or laid back, 2. exit points or ladders are not provided, 3. displays any evidence of instability, has any loose rock or other debris which could fall into the trench, or 4. displays any other evidence of any unsafe conditions regardless of depth. If the contractor fails to provide safe access to trenches for compaction testing, our company policy requires that the soil technician withdraws and notifies their supervisor. The contractors representative will then be contacted in an effort to effect a solution. All backfill not tested due to safety concerns or other reasons is subject to reprocessing and/or removal. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 7 901 E. Katella Avenue, Orange, California Project No. 3193-CR Procedures In the event that the technician's safety is jeopardized or compromised as a result of the contractor's failure to comply with any of the above, the technician is directed to inform both the developer's and contractor's representatives. If the condition is not rectified, the technician is required, by company policy, to immediately withdraw and notify their supervisor. The contractor’s representative will then be contacted in an effort to effect a solution. No further testing will be performed until the situation is rectified. Any fill placed in the interim can be considered unacceptable and subject to reprocessing, recompaction or removal. In the event that the soil technician does not comply with the above or other established safety guidelines, we request that the contractor bring this to technicians attention and notify our project manager or office. Effective communication and coordination between the contractors' representative and the field technician(s) is strongly encouraged in order to implement the above safety program and safety in general. The safety procedures outlined above should be discussed at the contractor's safety meetings. This will serve to inform and remind equipment operators of these safety procedures particularly the zone of non-encroachment.

Katella Avenue, Orange, California Project No. 3193-CR GENERAL GRADING GUIDELINES Guidelines presented herein are intended to address general construction procedures for earthwork construction. Specific situations and conditions often arise which cannot reasonably be discussed in general guidelines, when anticipated these are discussed in the text of the report. Often unanticipated conditions are encountered which may necessitate modification or changes to these guidelines. It is our hope that these will assist the contractor to more efficiently complete the project by providing a reasonable understanding of the procedures that would be expected during earthwork and the testing and observation used to evaluate those procedures. General Grading should be performed to at least the minimum requirements of governing agencies, Chapters 18 and 33 of the California Building Code, CBC (2019) and the guidelines presented below. Preconstruction Meeting A preconstruction meeting should be held prior to site earthwork. Any questions the contractor has regarding our recommendations, general site conditions, apparent discrepancies between reported and actual conditions and/or differences in procedures the contractor intends to use should be brought up at that meeting. The contractor (including the main onsite representative) should review our report and these guidelines in advance of the meeting. Any comments the contractor may have regarding these guidelines should be brought up at that meeting. Grading Observation and Testing 1. Observation of the fill placement should be provided by our representative during grading. Verbal communication during the course of each day will be used to inform the contractor of test results. The contractor should receive a copy of the "Daily Field Report" indicating results of field density tests that day. If our representative does not provide the contractor with these reports, our office should be notified. 2. Testing and observation procedures are, by their nature, specific to the work or area observed and location of the tests taken, variability may occur in other locations. The contractor is responsible for the uniformity of the grading operations; our observations and test results are intended to evaluate the contractor’s overall level of efforts during grading. The contractor’s personnel are the only individuals participating in all aspect of site work. Compaction testing and observation should not be considered as relieving the contractor’s responsibility to properly compact the fill. 3. Cleanouts, processed ground to receive fill, key excavations, and subdrains should be observed by our representative prior to placing any fill. It will be the contractor's responsibility to notify our representative or office when such areas are ready for observation. 4. Density tests may be made on the surface material to receive fill, as considered warranted by this firm. 5. In general, density tests would be made at maximum intervals of two feet of fill height or every 1,000 cubic yards of fill placed. Criteria will vary depending on soil conditions and size of the fill. More frequent testing may be performed. In any case, an adequate number of field density tests should be made to evaluate the required compaction and moisture content is generally being obtained. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 2 901 E. Katella Avenue, Orange, California Project No. 3193-CR 6. Laboratory testing to support field test procedures will be performed, as considered warranted, based on conditions encountered (e.g. change of material sources, types, etc.) Every effort will be made to process samples in the laboratory as quickly as possible and in progress construction projects are our first priority. However, laboratory workloads may cause in delays and some soils may require a minimum of 48 to 72 hours to complete test procedures. Whenever possible, our representative(s) should be informed in advance of operational changes that might result in different source areas for materials. 7. Procedures for testing of fill slopes are as follows: a) Density tests should be taken periodically during grading on the flat surface of the fill, three to five feet horizontally from the face of the slope. b) If a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. 8. Finish grade testing of slopes and pad surfaces should be performed after construction is complete. Site Clearing 1. All vegetation, and other deleterious materials, should be removed from the site. If material is not immediately removed from the site it should be stockpiled in a designated area(s) well outside of all current work areas and delineated with flagging or other means. Site clearing should be performed in advance of any grading in a specific area. 2. Efforts should be made by the contractor to remove all organic or other deleterious material from the fill, as even the most diligent efforts may result in the incorporation of some materials. This is especially important when grading is occurring near the natural grade. All equipment operators should be aware of these efforts. Laborers may be required as root pickers. 3. Nonorganic debris or concrete may be placed in deeper fill areas provided the procedures used are observed and found acceptable by our representative. Treatment of Existing Ground 1. Following site clearing, all surficial deposits of alluvium and colluvium as well as weathered or creep effected bedrock, should be removed unless otherwise specifically indicated in the text of this report. 2. In some cases, removal may be recommended to a specified depth (e.g. flat sites where partial alluvial removals may be sufficient). The contractor should not exceed these depths unless directed otherwise by our representative. 3. Groundwater existing in alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 4. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. 5. Exploratory back hoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Fill Placement 1. Unless otherwise indicated, all site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see text of report). GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 3 901 E. Katella Avenue, Orange, California Project No. 3193-CR 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts six (6) to eight (8) inches in compacted thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a nearly horizontal plane, unless otherwise found acceptable by our representative. 3. If the moisture content or relative density varies from that recommended by this firm, the contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be at or above optimum moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. The ability of the contractor to obtain the proper moisture content will control production rates. b) Each six-inch layer should be compacted to at least 90 percent of the maximum dry density in compliance with the testing method specified by the controlling governmental agency. In most cases, the testing method is ASTM Test Designation D 1557. 4. Rock fragments less than eight inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is observed by, and acceptable to, our representative. 5. Rocks exceeding eight (8) inches in diameter should be taken off site, broken into smaller fragments, or placed in accordance with recommendations of this firm in areas designated suitable for rock disposal. On projects where significant large quantities of oversized materials are anticipated, alternate guidelines for placement may be included. If significant oversize materials are encountered during construction, these guidelines should be requested. 6. In clay soil, dry or large chunks or blocks are common. If in excess of eight (8) inches minimum dimension, then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break up blocks. When dry, they should be moisture conditioned to provide a uniform condition with the surrounding fill. Slope Construction 1. The contractor should obtain a minimum relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. 2. Slopes trimmed to the compacted core should be overbuilt by at least three (3) feet with compaction efforts out to the edge of the false slope. Failure to properly compact the outer edge results in trimming not exposing the compacted core and additional compaction after trimming may be necessary. 3. If fill slopes are built "at grade" using direct compaction methods, then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled or otherwise compacted at approximately every 4 feet vertically as the slope is built. 4. Corners and bends in slopes should have special attention during construction as these are the most difficult areas to obtain proper compaction. 5. Cut slopes should be cut to the finished surface. Excessive undercutting and smoothing of the face with fill may necessitate stabilization. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 4 901 E. Katella Avenue, Orange, California Project No. 3193-CR UTILITY TRENCH CONSTRUCTION AND BACKFILL Utility trench excavation and backfill is the contractors responsibility. The geotechnical consultant typically provides periodic observation and testing of these operations. While efforts are made to make sufficient observations and tests to verify that the contractors’ methods and procedures are adequate to achieve proper compaction, it is typically impractical to observe all backfill procedures. As such, it is critical that the contractor use consistent backfill procedures. Compaction methods vary for trench compaction and experience indicates many methods can be successful. However, procedures that “worked” on previous projects may or may not prove effective on a given site. The contractor(s) should outline the procedures proposed, so that we may discuss them prior to construction. We will offer comments based on our knowledge of site conditions and experience. 1. Utility trench backfill in slopes, structural areas, in streets and beneath flat work or hardscape should be brought to at least optimum moisture and compacted to at least 90 percent of the laboratory standard. Soil should be moisture conditioned prior to placing in the trench. 2. Flooding and jetting are not typically recommended or acceptable for native soils. Flooding or jetting may be used with select sand having a Sand Equivalent (SE) of 30 or higher. This is typically limited to the following uses: a) shallow (12 + inches) under slab interior trenches and, b) as bedding in pipe zone. The water should be allowed to dissipate prior to pouring slabs or completing trench compaction. 3. Care should be taken not to place soils at high moisture content within the upper three feet of the trench backfill in street areas, as overly wet soils may impact subgrade preparation. Moisture may be reduced to 2% below optimum moisture in areas to be paved within the upper three feet below sub grade. 4. Sand backfill should not be allowed in exterior trenches adjacent to and within an area extending below a 1:1 projection from the outside bottom edge of a footing, unless it is similar to the surrounding soil. 5. Trench compaction testing is generally at the discretion of the geotechnical consultant. Testing frequency will be based on trench depth and the contractors procedures. A probing rod would be used to assess the consistency of compaction between tested areas and untested areas. If zones are found that are considered less compact than other areas, this would be brought to the contractors attention. JOB SAFETY General Personnel safety is a primary concern on all job sites. The following summaries are safety considerations for use by all our employees on multi-employer construction sites. On ground personnel are at highest risk of injury and possible fatality on grading construction projects. The company recognizes that construction activities will vary on each site and that job site safety is the contractor's responsibility. However, it is, imperative that all personnel be safety conscious to avoid accidents and potential injury. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 5 901 E. Katella Avenue, Orange, California Project No. 3193-CR In an effort to minimize risks associated with geotechnical testing and observation, the following precautions are to be implemented for the safety of our field personnel on grading and construction projects. 1. Safety Meetings: Our field personnel are directed to attend the contractor's regularly scheduled safety meetings. 2. Safety Vests: Safety vests are provided for and are to be worn by our personnel while on the job site. 3. Safety Flags: Safety flags are provided to our field technicians; one is to be affixed to the vehicle when on site, the other is to be placed atop the spoil pile on all test pits. In the event that the contractor's representative observes any of our personnel not following the above, we request that it be brought to the attention of our office. Test Pits Location, Orientation and Clearance The technician is responsible for selecting test pit locations. The primary concern is the technician's safety. However, it is necessary to take sufficient tests at various locations to obtain a representative sampling of the fill. As such, efforts will be made to coordinate locations with the grading contractors authorized representatives (e.g. dump man, operator, supervisor, grade checker, etc.), and to select locations following or behind the established traffic pattern, preferably outside of current traffic. The contractors authorized representative should direct excavation of the pit and safety during the test period. Again, safety is the paramount concern. Test pits should be excavated so that the spoil pile is placed away from oncoming traffic. The technician's vehicle is to be placed next to the test pit, opposite the spoil pile. This necessitates that the fill be maintained in a drivable condition. Alternatively, the contractor may opt to park a piece of equipment in front of test pits, particularly in small fill areas or those with limited access. A zone of non-encroachment should be established for all test pits (see diagram below). No grading equipment should enter this zone during the test procedure. The zone should extend outward to the sides approximately 50 feet from the center of the test pit and 100 feet in the direction of traffic flow. This zone is established both for safety and to avoid excessive ground vibration, which typically decreases test results. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 6 901 E.

INTRODUCTION AND LOCATION A paleontological resource assessment has been completed for the 901 East Katella Avenue Project located at 901 East Katella Avenue at the northeast corner of the intersection of North Cambridge Street with Katella Avenue in the city of Orange, Orange County, California (Figures 1 and 2). The 2.71-acre project consists of one parcel, assigned with Assessor’s Parcel Number (APN) 375-461-41. On the United States Geological Survey (7.5-minute) 1:24,000- scale Orange, California topographic quadrangle map, the project is situated in an unsectioned area of Township 4 South, Range 9 West, of the San Bernardino Baseline and Meridian (Figure 2). The project proposes to demolish the property’s existing structures and construct 26 two- story residential duplexes. The development will include utility infrastructure, pavement, flatwork, and landscaping. As the lead agency, the City of Orange has required the preparation of a paleontological assessment to evaluate the project’s potential to yield paleontological resources. The paleontological assessment of the project included a review of paleontological literature and fossil locality records in the area; a review of the underlying geology; and recommendations to mitigate impacts to potential paleontological resources, if necessary. A paleontological field survey was not conducted since the surface of the project property is completely developed. II. REGULATORY SETTING The California Environmental Quality Act (CEQA), which is patterned after the National Environmental Policy Act, is the overriding environmental regulation that sets the requirement for protecting California’s paleontological resources. CEQA mandates that governing permitting agencies (lead agencies) set their own guidelines for the protection of nonrenewable paleontological resources under their jurisdiction. State of California Under “Guidelines for Implementation of the California Environmental Quality Act,” as amended in December 2018 (California Code of Regulations [CCR] Title 14, Division 6, Chapter 3, Sections 15000 et seq.), procedures define the types of activities, persons, and public agencies required to comply with CEQA. Section 15063 of the CCR provides a process by which a lead agency may review a project’s potential impact to the environment, whether the impacts are significant, and provide recommendations, if necessary. Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 4 In CEQA’s Environmental Checklist Form, one of the questions to answer is, “Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?” (Appendix G, Section VII, Part f). This is to ensure compliance with California Public Resources Code Section 5097.5, the law that protects nonrenewable resources, including fossils, which is paraphrased below: a) A person shall not knowingly and willfully excavate upon, or remove, destroy, injure or deface any historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological site, including fossilized footprints, inscriptions made by human agency, rock art, or any other archaeological, paleontological or historical feature, situated on public lands, except with the express permission of the public agency having jurisdiction over such lands. b) As used in this section, “public lands” means lands owned by, or under the jurisdiction of, the state, or any city, county, district, authority, or public corporation, or any agency thereof. c) A violation of this section is a misdemeanor. County of Orange Section 2-5-27(c) of Article 2 of the Codified Ordinances of Orange County includes protection measures for “natural, cultural, structural, and archeological resources” in recreational areas and mandates that: No person shall possess, destroy, injure, deface, remove, dig, or disturb from its natural state any fossilized or nonfossilized paleontological specimens, cultural or archaeological resources, or the parts thereof in any park, beach or recreational facility. (County of Orange 2005) Similarly, Section 2-5-227(c) of Article 9 of the Codified Ordinances of Orange County includes protection measures for “natural, cultural, structural, and archeological resources” in privately owned parks and mandates that: No person shall possess, destroy, injure, deface, remove, dig, or disturb from its natural state any fossilized or nonfossilized paleontological specimens, cultural or archaeological resources, or the parts thereof in any designated park. (County of Orange 2005) Eisentraut and Cooper (2002) introduced a curation model with monitoring and mitigation guidelines for the conservation of archaeological and paleontological materials in the Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 5 County of Orange. This document and its recommendations were subsequently adopted by the Orange County Board of Supervisors and now provide a standard for the paleontological profession to use in the paleontological mitigation process in Orange County. In 2009, the John D. Cooper Archaeology and Paleontology Center (“the Cooper Center”) was formally organized in Santa Ana with the intent to provide a repository to receive future incoming collections. Operation of the Cooper Center was initially a joint partnership between the County of Orange and California State University, Fullerton. In 2019, Orange County Parks (OC Parks) took over administration of the facility. City of Orange Paleontological resources are not covered in the City’s general plan or environmental impact report (City of Orange 2010). III. GEOLOGY The current path of the Santa Ana River lies approximately one-and-a-half miles west of the project. Geologically, the surficial sediments across the project are mapped as late to middle Pleistocene-aged old alluvial fan deposits (amber areas labeled “Qofsa” on Figure 3), mostly consisting of unconsolidated, alluvial silty sands (Morton and Miller 2006). These deposits represent the erosional detritus transported and deposited by Santiago Creek, east of the project, during the wetter climatic conditions of the Pleistocene. IV. PALEONTOLOGICAL RESOURCES Definition Paleontological resources are the remains of prehistoric life that have been preserved in geologic strata. These remains are called fossils and include bones, shells, teeth, and plant remains (including their impressions, casts, and molds) in the sedimentary matrix, as well as trace fossils such as footprints and burrows. Fossils are considered older than 5,000 years of age (Society of Vertebrate Paleontology 2010) but may include younger remains (subfossils), for example, when viewed in the context of local extinction of the organism or habitat. Fossils are considered a nonrenewable resource under state and local guidelines (see Section II of this report). Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 7 Fossil Locality Search Fossil locality record searches conducted for prior projects by Brian F. Smith and Associates were consulted to research potential nearby fossil localities. Sources for locality data are from the Natural History Museum of Los Angeles County (LACM) and OC Parks. The records searches indicate that no fossil localities were identified within the project boundaries or close to the project. The nearest listed fossil locality is that of a Pleistocene sheep discovered during a housing development along South Rio Vista Street in Anaheim, about two miles northwest of the project (LACM locality [loc.] 1652). Remains of a Pleistocene proboscidean (elephant family) were found approximately three to four miles to the northeast along Richfield Road in Placentia (LACM loc. 3292). From prior records searches, OC Parks indicated that they have no nearby fossil localities in similar sedimentary deposits as the current project. A review of published and unpublished literature was conducted for potential paleontological resources that may be known in the vicinity of the project. Data reported in Miller (1971) indicate there are no nearby fossil localities. Jefferson (1991) lists a late Pleistocene-aged specimen of horse located at “Glasell [Street] and Fletcher [Avenue]” in Orange (LACM loc. 4943), about a mile-and-a-half north of the project. V. PALEONTOLOGICAL SENSITIVITY Overview The degree of paleontological sensitivity of any particular area is based on a number of factors, including the documented presence of fossiliferous resources on a site or in nearby areas, the presence of documented fossils within a particular geologic formation or lithostratigraphic unit, and whether or not the original depositional environment of the sediments is one that might have been conducive to the accumulation of organic remains that might have become fossilized over time. Holocene alluvium is generally considered to be geologically too young to contain significant nonrenewable paleontological resources (i.e., fossils), and is therefore typically assigned a low paleontological sensitivity. Pleistocene (more than 11,700 years old) alluvial and alluvial fan deposits in the Los Angeles Basin, however, often yield important Ice Age terrestrial vertebrate fossils, such as extinct mammoths, mastodons, giant ground sloths, extinct species of horse, bison, and camel, saber-toothed cats, and others (Jefferson 1991). These Pleistocene sediments are accorded a high paleontological resource sensitivity. Professional Standards The Society of Vertebrate Paleontology (SVP 2010) has drafted guidelines that include four categories of paleontological sensitivity for geologic units (formations) that might be impacted by a proposed project, as listed below: Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 8 • High Potential: Rock units from which vertebrate or significant invertebrate, plant, or trace fossils have been recovered. • Undetermined Potential: Rock units for which little information is available concerning their paleontological content, geologic age, and depositional environment; further study is needed to determine the potential of the rock unit. • Low Potential: Rock units that are poorly represented by fossil specimens in institutional collections or based on a general scientific consensus that only preserve fossils in rare circumstances. • No Potential: Rock units that have no potential to contain significant paleontological resources, such as high-grade metamorphic rocks and plutonic igneous rocks. Using these criteria, based on a Pleistocene age for the surficial sedimentary deposits at the project, Pleistocene vertebrate fossils in the area, and the regional geology, a high paleontological potential may be assigned to the project. VI. CONCLUSIONS AND RECOMMENDATIONS The existence of Pleistocene old alluvial fan deposits at the surface of the project, the high paleontological resource sensitivity assigned to these sediments, and the presence of previously recorded fossil specimens from the similar deposits less than five miles of the property all support the recommendation that full-time paleontological monitoring be required starting at a depth of five feet below the surface during grading, excavation, or utility trenching activities at the project. The project paleontologist should have the discretion of adjusting the monitoring schedule based on any changing geological conditions observed during monitoring. A paleontological mitigation monitoring program is proposed and must be consistent with the provisions of CEQA, the City of Orange, and those of the guidelines of the SVP (2010). If implemented, the program report would mitigate any adverse impacts (loss or destruction) to potential nonrenewable paleontological resources (fossils), if present, to less than significant. A proposed paleontological mitigation monitoring program is as follows: 1. Prior to initiation of any grading, drilling, and/or excavation activities, a preconstruction meeting will be held and attended by the paleontologist of record, representatives of the grading contractor and subcontractors, the project owner or developer, and a representative of the lead agency. The nature of potential paleontological resources shall be discussed, as well as the protocol that is to be implemented following discovery of any fossiliferous materials. 2. Monitoring of mass grading and excavation activities shall be performed by a qualified paleontologist or paleontological monitor. Monitoring will be conducted full-time in areas of grading or excavation in undisturbed sediments of Pleistocene Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 9 old alluvial fan deposits starting at a depth of five feet. The project paleontologist should have the discretion of adjusting the monitoring schedule based on any changing geological conditions observed during monitoring. 3. Paleontological monitors will be equipped to salvage fossils as they are unearthed to avoid construction delays. The monitor must be empowered to temporarily halt or divert equipment to allow removal of abundant or large specimens in a timely manner. Monitoring may be reduced if the potentially fossiliferous units are not present in the subsurface or, if present, are determined upon exposure and examination by qualified paleontological personnel to have low potential to contain fossil resources. 4. Paleontological salvage during trenching and boring activities is typically from the generated spoils and does not delay the trenching or drilling activities. Fossils are collected and placed in cardboard flats or plastic buckets and identified by field number, collector, and date collected. Notes are taken on the map location and stratigraphy of the site, and the site is photographed before it is vacated and the fossils are removed to a safe place. On mass grading projects, any discovered fossil site is protected by red flagging to prevent it from being overrun by earthmovers (scrapers) before salvage begins. Fossils are collected in a similar manner, with notes and photographs being taken before removing the fossils. Precise location of the site is determined with the use of handheld Global Positioning System units. If the site involves a large terrestrial vertebrate, such as large bone(s) or a mammoth tusk, that is/are too large to be easily removed by a single monitor, a fossil recovery crew will excavate around the find, encase the find within a plaster and burlap jacket, and remove it after the plaster is set. For large fossils, use of the contractor’s construction equipment is solicited to help remove the jacket to a safe location before it is returned to the laboratory facility for preparation. 5. Isolated fossils are collected by hand, wrapped in paper, and placed in temporary collecting flats or five-gallon buckets. Notes are taken on the map location and stratigraphy of the site, and the site is photographed before it is vacated and the fossils are removed to a safe place. 6. Particularly small invertebrate fossils typically represent multiple specimens of a limited number of organisms, and a scientifically suitable sample can be obtained from one to several five-gallon buckets of fossiliferous sediment. If it is possible to dry-screen the sediment in the field, a concentrated sample may consist of one or two buckets of material. For vertebrate fossils, the test is usually the observed presence of small pieces of bones within the sediments. If present, multiple five-gallon buckets of sediment can be collected and returned to a separate facility to wet-screen the sediment. 7. In accordance with the “Microfossil Salvage” section of the Society of Vertebrate Paleontological Assessment for the 901 East Katella Avenue Project _____________________________________________________________________________________________________________________ 10 Paleontology guidelines (2010:7), bulk sampling and screening of fine-grained sedimentary deposits (including carbonate-rich paleosols) must be performed if the deposits are identified to possess indications of producing fossil “microvertebrates” in order to test the feasibility of the deposit to yield fossil bones and teeth. 8. In the laboratory, individual fossils are cleaned of extraneous matrix, any breaks are repaired, and the specimen, if needed, is stabilized by soaking in an archivally approved acrylic hardener (e.g., a solution of acetone and Paraloid B-72). 9. Preparation of recovered specimens to a point of identification and permanent preservation (not display), including screen-washing sediments to recover small invertebrates and vertebrates. Preparation of individual vertebrate fossils is often more time-consuming than for accumulations of invertebrate fossils. 10. Identification and curation of specimens into a professional, accredited public museum repository with a commitment to archival conservation and permanent retrievable storage (e.g., OC Parks in Santa Ana, California). The paleontological program should include a written repository agreement prior to the initiation of mitigation activities. The lead agency may select another repository if it so desires. 11. Preparation of a final monitoring and mitigation report of findings and significance, including lists of all fossils recovered and necessary maps and graphics to accurately record their original location(s). The report, when submitted to and accepted by the appropriate lead agency, will signify satisfactory completion of the project program to mitigate impacts to any potential nonrenewable paleontological resources (i.e., fossils) that might have been lost or otherwise adversely affected without such a program in place.

(Partner) has performed a Phase I Environmental Site Assessment (ESA) in accordance with the scope of work and limitations of ASTM Standard Practice E1527-13 and E1527-21, the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (AAI) (40 CFR Part 312) and set forth by Intracorp SW, LLC for the property located at 901 East Katella in Orange, Orange County, California (the “subject property”). Property Description The subject property is located on the north side of East Katella Avenue and the east side of North Cambridge Street within a mixed commercial and residential area of Orange County. Partner understands that redevelopment for residential use is proposed. Please refer to the table below for further description of the subject property: Subject Property Data Address: 901 East Katella, Orange, California Historical Address: 905 East Katella Property Use: Vacant office Land Acreage (Ac): 2.73 Ac Number of Buildings: One with covered storage area Number of Floors: One Gross Building Area (SF): 20,000 SF (Total) Net Rentable Area (SF): Not provided Date of Construction: 1969 Assessor’s Parcel Number (APN): 375-461-41 Type of Construction: Metal-framed Current Tenants: Vacant Site Assessment Performed By: Tomo Demers of Partner Site Assessment Conducted On: May 3, 2022 Regulatory Radius Report Date: April 29, 2022 Lien Search Date: NA Report Date: May 13, 2022 FOIAs Date: May 2022 The subject property is currently unoccupied office space. At the time of Partner’s site assessment, the interior appeared to be damaged and have former signs of vagrancy. In addition to the current structure, the subject property is improved with a covered storage area and cell phone tower located east of the building, an asphalt-paved parking lot, associated landscaping and two gated entryways located on the southern and western portions of the property. According to available historical sources, the subject property was formerly unimproved land as early as 1896 to 1935; developed with agricultural land (orchard) between 1938 and circa 1963; grade land in 1968; and developed with the current structure in 1970. Tenants on the subject property include various telephone and cable related services (1970-2020). The adjoining properties are tabulated below: Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page ii Adjoining Properties North: Residences (918-1102 East Carleton Avenue) East: Commercial retail/offices (1111 East Katella Avenue) Southeast: East Katella Avenue beyond which is Albert & James Photographers (1010 East Katella) South: East Katella Avenue beyond which is Hybrid Academy/Orange County Mattress (900, 950 and 1010 East Katella) Southwest: East Katella Avenue beyond which is Mobil (830 East Katella) West: North Cambridge Street beyond which is Speedway Express (825 East Katella) Northwest: North Cambridge Street beyond which is Cambridge Court Apartments (1350 North Cambridge Street) According to a previous subsurface investigation conducted on a nearby property (825 East Katella Avenue, Case #09UT004) the physical setting features of the subject property identify the terrain as sloping to the southwest with the depth to groundwater in the vicinity of the subject property inferred to be approximately 175 feet below ground surface (bgs) and groundwater flow inferred to be toward the southwest. Findings and Opinions Recognized Environmental Condition A recognized environmental condition (REC) refers to the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment. The following was identified during the course of this assessment: • Partner did not identify any RECs during the course of this assessment. Controlled Recognized Environmental Condition A co ntrolled recognized environmental condition (CREC) refers to a REC affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations). The following was identified during the course of this assessment: • Partner did not identify any CRECs during the course of this assessment. Historical Recognized Environmental Condition A historical recognized environmental condition (HREC) refers to a previous release of hazardous substances or petroleum products affecting the subject property that has been addressed to the satisfaction of the applicable regulator y authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the subject property to any controls (for example, activity and use limitations or other property use limitations). The following was identified during the course of this assessment: Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page iii • Partner was provided with an ESA dated March 26, 2014 prepared by BA Environmental (BA). BA reviewed Orange Fire Department (OFD) files regarding the subject property. Records indicate that a 4,000 gallon diesel underground storage tank (UST) was formerly located on the subject property near the northeast corner of the building. This UST was reportedly installed in 1992 to power an emergency generator operated by AT&T. According to OFD files, the UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The UST excavation was backfilled with stockpiled soil and supplemented with imported clean fill. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 stating that no significant contamination has occurred and the UST removal project is closed. The Orange County Environmental Health Care Agency (OCHCA) and OFD were in concurrence that no significant soil contamination was discovered from the former UST located on the subject property. No further action was required by either agency. Based on the lack of a detected leak, good condition of the removed UST, issuance of a case closure letter, the former UST removed at the subject property satisfied to the requirements of OFD and OCHCA represents a HREC. Partner opines that further evaluation of the removed UST is not warranted. Business Environmental Risk A Business Environmental Risks (BER) is a risk which can have a material environmental or environmentally driven impact on the business associated with the current or planned use of commercial real estate, not necessarily related to those environmental issues required to be investigated in this practice. The following was identified during the course of this assessment: • Due to the age of the subject proper ty building, there is a potential that asbestos-containing material (ACM) and/or lead-based paint (LBP) are present. Should these materials be replaced or removed, the identified suspect ACMs would need to be sampled to co nfirm the presence or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants. LBP can be managed in place if adhered. Significant Data Gaps No significant data gaps affecting the ability of the Environmental Professional to identify a REC were encountered during this assessment. Conclusions and Recommendations Partner has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E1527-13 and E1527-21 of 901 East Katella Avenue, Orange, Orange County, California (the “subject property”). Any exceptions to, or deletions from, this practice are described in Section 1.5 of this report. This assessment has revealed evidence of an HREC an d BERs in connection with the subject property. Based on the conclusions of this assessment, Partner recommends the following: Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page iv • In accordance with requirements by local agencies, sampling of suspect ACM and removal as needed prior to demolition of the building. LBP can be managed in place if adhered.

Assessment Project No. 22-367781.1 May 13, 2022 Page 1 1.0 INTRODUCTION Partner Engineering and Science, Inc. (Partner) has performed a Phase I Environmental Site Assessment (ESA) in conformance with the scope and limitations of ASTM Standard Practice E1527-13 and E1527-21 and the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (AAI) (40 CFR Part 312) for the property located at 901 East Katella, Orange, Orange County, California (the “subject property”). Any exceptions to, or deletions from, this scope of work are described in the report. 1.1 Purpose The purpose of this ESA is to identify existing or potential Recognized Environmental Conditions (as defined by ASTM Standard E1527-13 and E1527-21) affecting the subject property that: 1) constitute or result in a material violation or a potential material violation of any applicable environmental law; 2) impose any material constraints on the operation of the subject property or require a material change in the use thereof; 3) require clean-up, remedial action or other response with respect to Hazardous Substances or Petroleum Products on or affecting the subject property under any applicable environmental law; 4) may affect the value of the subject property; and 5) may require specific actions to be performed with regard to such conditions and circumstances. The information contained in the ESA Report will be used by Client to: 1) evaluate its legal and financial liabilities for transactions related to foreclosure, purchase, sale, loan origination, loan workout or seller financing; 2) evaluate the subject property’s overall development potential, the associated market value and the impact of applicable laws that restrict financial and other types of assistance for the future development of the subject property; and/or 3) determine whether specific actions are required to be performed prior to the foreclosure, purchase, sale, loan origination, loan workout or seller financing of the subject property. This ESA was performed to permit the User to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on scope of Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 U.S.C. §9601) liability (hereinafter, the “landowner liability protections,” or “LLPs”). ASTM Standard E1527-13 constitutes “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined at 42 U.S.C. §9601(35)(B). 1.2 Scope of Work The scope of work for this ESA is in accordance with and to the extent necessary to achieve the goal of the requirements set forth in the ASTM Standard E1527-13 and E1527-21. This assessment included: 1) a property and adjoining site reconnaissance; 2) interviews with key personnel; 3) a review of historical sources; 4) a review of regulatory agency records; and 5) a review of a regulatory database report provided by a third-party vendor. Partner contacted local agencies, such as environmental health departments, fire departments and building departments to obtain readily ascertainable information to determine any current and/or former hazardous substances usage, storage and/or releases of hazardous substances on the subject property. Additionally, Partner researched readily available information on the presence of activity and use limitations (AULs) at these agencies. As defined by ASTM E1527-21, AULs include both legal (that is, institutional) and physical (that is, engineering) controls that may include legal or physical restrictions or limitations on the use of, or access to, a site or facility: 1) to reduce or eliminate Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 2 potential exposure to hazardous substances or petroleum products in the soil, soil vapor, groundwater, or surface water on the subject property; or 2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment.

Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 4 2.0 SITE DESCRIPTION 2.1 Site Location and Legal Description The subject property at 901 East Katella Avenue in Orange, California is located on the north side of East Katella Avenue and the east side of North Cambridge Street. According to the online research, the subject property is legally described as A TR VAN DE GRAAFF TR BLK LOT H. According to documentation provided by the client, ownership has been vested in Pacific Bell Telephone Company since 2000. Please refer to Figure 1: Site Location Map, Figure 2: Site Plan, Figure 3: Topographic Map, and Appendix A: Site Photographs for the location and site characteristics of the subject property. 2.2 Current Property Use The subject property is currently uno ccupied office space. At the time of the site visit the interior appeared to be damaged and have former signs of vagrancy. In addition to the current structure, the subject property is improved with a covered storage area and cell phone tower located east of the building, an asphalt-paved parking lot, associated landscaping and two gated entryways located on the southern and western portions of the property. The subject property is designated for commercial development by the City of Orange. The subject property was identified as a Delisted Storage Tanks (DELISTED TNK), Facility Registry Service/Facility Index (FINDS/FRS), Delisted Environmental Reporting System (CERS) Hazardous Waste Sites (DELISTED HAZ), Statewide Environmental Evaluation and Planning System (UST SWEEPS) site in the regulatory database report, as further discussed in Section 4.2. 2.3 Current Use of Adjoining Properties The subject property is lo cated within a mixed commercial and residential area of Orange County. During the vicinity reconnaissance, Partner observed the land uses on adjoining properties as defined in ASTM E1527-13 and E1527-21 as any real property or properties the border of which is contiguous or partially contiguous with that of the property, or that would be contiguous or partially contiguous with that of the property but for a street, road, or other public thoroughfare separating them. The adjoining properties are tabulated below: Adjoining Properties North: Residences (918-1102 East Carleton Avenue) East: Commercial retail/offices (1111 East Katella Avenue) Southeast: East Katella Avenue beyond which is Albert & James Photographers (1010 East Katella) South: East Katella Avenue beyond which is Hybrid Academy/Orange County Mattress (950 and 1010 East Katella) Southwest: East Katella Avenue beyond which is Mobil (830 East Katella) West: North Cambridge Street beyond which is Speedway Express (825 East Katella) Northwest: North Cambridge Street beyond which is Cambridge Court Apartments (1350 North Cambridge Street) The adjoining property to the south was identified as a Hazardous Waste Manifest Data (HAZNET) site in the regulatory database report of Section 4.2. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 5 The adjoining property to the west was identified as a DELISTED TNK, Leaking Underground Fuel Tank (LUST), Historical Hazardous Substance Storage Information Database (HHSS), Historical Hazardous Substance Storage Container Information (HIST TANK), Resource Conservation and Recovery Act Small Quantity Generators (RCRA SQG), Orange County Hazardous Waste Facilities (HW ORANGE), Active UST Facilities (UST), Toxic Pollutant Emissions Facilities (EMISSIONS), Orange County Local Oversight Case List (LOP ORANGE), California Environmental Reporting System Tanks (CERS TANK), Resource Conservation and Recovery Act Non-Generators (RCRA NON-GEN) site in the regulatory database report of Section 4.2. The adjoining property to the southwest was identified as a UST SWEEPS, RCRA SQG, HHSS, HW ORANGE, UST, EMISSIONS, LOP ORANGE, CERS TANK, RCRA NON-GEN, DELISTED TNK, HIST TANK site in the regulatory database report of Section 4.2. 2.4 Physical Setting Sources 2.4.1 Topography The 2022 United States Geological Survey (USGS) Orange, California Quadrangle 7.5-minute series topographic map was reviewed for this ESA. According to the contour lines on the topographic map, the subject property is located at approximately 226 feet above mean sea level (MSL). The contour lines in the area of the subject property indicate the area is sloping toward the west. A copy of the most recent topographic map is included as Figure 3 of this report. 2.4.2 Hydrology While under natural and undisturbed conditions shallow groundwater flow most frequently follows the topography of the land surface, natural or man-made features can affect flow direction, and the presumed flow may not match the actual flow directions at the subject property and vicinity. Topographic map interpretation suggests the direction of groundwater flow in the vicinity of the subject property is inferred to be to ward the west. According to a subsurface investigation conducted on a nearby property (825 East Katella Avenue, Case #09UT004) depth to groundwater in the vicinity of the subject property inferred to be approximately 175 feet below ground surface (bgs). The nearest surface water to the subject property is the Collins Channel portion of the Santa Ana River located approximately 1.0 mile to the west of the subject property. No settling ponds, lagoons, surface impoundments, wetlands or natural catch basins were observed at the subject property during this assessment. According to available information, a public water system operated by the Orange Water Department serves the subject property vicinity. The source of public water for Orange is groundwater drawn from twelve municipal wells drilled about 1,000 feet into the Santa Ana River Aquifer. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 6 2.4.3 Geology/Soils Based on information obtained from the United States Department of Agriculture (USDA) Natural Resources Conservation Service Web Soil Survey online database, the subject property is mapped as Myford sandy loam. The soils of the Myford Series are deep, moderately well drained soils with medium to rapid runoff and very slow permeability, formed on terraces. Slopes range from 0 to 2 percent. The subject property is situated within the Peninsular Ranges physiographic province of the State of California. The uppermost geologic formation underlying the soils at the subject property are granitic and metamorphic cores of Mesozoic age, flanked by sedimentary rocks ranging from Cretaceous to Quaternary in age called the Bedford Canyon formation. The Bedford Canyon formation comprises the underlying stratigraphy and consists mostly of marine sedimentary rocks. The thickness of the Beaumont formation is estimated to be over 200 feet. The Bedford Canyon formation is underl ain by the Los Angeles basin formations, which are estimated to be a total of approximately 1,200 feet thick. 2.4.4 Flood Zone Information Partner performed a review of the Flood Insurance Rate Map, published by the Federal Emergency Management Agency. According to Community Panel Number 06059C0161J, dated December 3, 2009, the subject property appears to be located in Zone X, an area located outside of the 100-year and 500- year flood plains. A copy of the reviewed flood map is included in Appendix B of this report. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 7 3.0 HISTORICAL INFORMATION Partner obtained historical use information about the subject property from a variety of sources. A chronological listing of the historical data found is summarized in the table below: Historical Use Information Years Resource Description/Use 1896-1935 Topographic Maps Unimproved land 1938-1963 Aerial Photographs, Topographic Map Agricultural land (orchards) 1968 Aerial Photographs Graded land 1970-Present Aerial Photographs, City Directories, Onsite Observations, Prior Report Commercial Tenants on the subject property include various telephone and cable related service companies (1970- 2020). No potential environmental concerns were identified in association with the current or former use of the subject property. The subject property parcel was historically used for agricultural purposes. There is the potential that agricultural related chemicals such as pesticides, herbicides, and fertilizers, may have been used and stored onsite. The subject property is either paved over or covered by structures that minimize direct contact to any potential remaining contaminants in the soil. Additionally, during previous site development activities, near surface soils (where residual agricultural chemical concentrations would have most likely been present, if at all) were likely mixed with fill material or disturbed during grading. Also, it is common that engineered fill is placed over underlying soils as part of the development activities. These additional variables serve to fu rther reduce the potential for exposure to residual agricultural chemicals (if any). Based on these reasons, Partner concludes that the potential former use of agricultural chemicals is not expected to represent a significant environmental concern at this time. 3.1 Aerial Photograph Review Partner obtained available aerial photographs of the subject property and surrounding area from Environmental Risk Information Services (ERIS) on April 29, 2022.

The subject property, identified as Pacific Bell at 901 Katella Avenue, is listed on the DELISTED TNK and UST SWEEPS database. According to the databases, Pacific Bell previously maintained a 4,000-gallon UST containing diesel, which was reportedly installed on May 24, 1993. Based on documentation provided by the Client, a case closure letter was issued to AT&T California from the OFD on May 30, 2013, after soil samples collected during the tank removal were representative of no soil contamination having occurred in association with the former UST at the subject property. Based on the issuance of a case closure/no further action letter, the former UST removed at the subject property satisfied to the requirements of OFD represents a HREC and these listings are not expected to represent a significant environmental concern. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 20 Based on the findings, vapor migration is not expected to represent a significant environmental concern at this time. 4.2.3 Adjoining Property Listings The adjoining property to the south is identified as a HAZNET site in the regulatory database report, as discussed below: • The property, identified as Schilstra Chiropractic Office/Walter Ziener DDS/ W.A. Ziemer DDS/Cambridge Dental Care at 900 East Katella Avenue across Katella Avenue to the south, is listed on the HAZNET database. According to the database, Schilstra Chiropractic Office/Walter Ziener DDS/W.A. Ziemer DDS/Cambrige Dental Care is listed as hazardous waste generator and/or chemical storage facility with EPA IDs: CAL000114745, CAL000113429, CAL000113648, and CAL000146819. According to the DTSC Hazardous Waste Manifest Database, this site is documented as generated the following hazardous materials: Facility Name/EPA ID Hazardous Materials Entry Date Status Schilstra Chiropractic Office (CAL000114745) Not specified November 12, 1993 Inactive as of June 30, 1998 Walter Ziener DDS (CAL000113429) Not specified June 12, 1993 Inactive as of June 30, 1993 W.A.

The adjoining property to the west is identified as a DELISTED TNK, LUST, HHSS, HIST TANK, RCRA SQG, HW ORANGE, UST, EMISSIONS, LOP ORANGE, CERS TANK, and RCRA NON-GEN site in the regulatory database report, as discussed below: • The property, identified as Thrifty Oil Co #367 at 825 East Katella Avenue across Cambridge Street to the west, is listed on the DELISTED TNK, LUST, HHSS, HIST TANK, RCRA SQG, HW ORANGE, UST, EMISSIONS, LOP ORANGE, CERS TANK, and RCRA NON-GEN databases. According to the information provided on the GeoTracker database, the adjoining property reported a release of gasoline, which reportedly impacted soil only. The source of the release was not identified; Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 21 however, after subsequent soil sampling, a regulatory case closure was granted without remedial activities on April 17, 2000. A secondary case, identified as ARCO #9733, was eventually opened with the Orange County Local Oversight Program (LOP) on February 26, 2009, when soil sampling was conducted during dispenser upgrade activities. According to the information provided on the GeoTracker database, the adjoining property reported a release of gasoline/Methyl tert-butyl ether (MTBE)/Tertiary butyl alcohol (TBA) on or before February 26, 2009, which reportedly impacted soil only. Subsequent soil investigations by Status Environmental Inc (Stratus) from June 2010 and October 2010 indicated that petroleum hydrocarbons detected during dispenser upgrade activities in February 2009 have not significantly impacted shallow soil beneath the site or have adversely impacted groundwater resources in the area. The responsible party is identified as Shyamala Kalyanasundaram, and regulatory closure was obtained on September 24, 2010. Based on the issuance of a regulatory closure letter, distance of the impacted soil to the subject property boundary, and the regulatory oversight/status, this listing is not expected to represent a significant environmental concern and it is unlikely that a r egulatory file review for this site would alter the findings of this assessment. The adjoining property to the south west is identified as a UST SWEEPS, RCRA SQG, HHSS, HW ORANGE, UST, EMISSIONS, LOP ORANGE, CERS TANK, RCRA NON-GEN, DELISTED TNK, HIST TANK site in the regulatory database report, as discussed below: • The property, identified as Texaco Service Station at 830 East Katella Avenue across Cambridge Street to the southwest, is listed on the UST SWEEPS, RCRA SQG, HHSS, HW ORANGE, UST, EMISSIONS, LOP ORANGE, CERS TANK, RCRA NON-GEN, DELISTED TNK, and HIST TANK databases. According to the information provided on the GeoTracker database, the adjoining property reported a release of gasoline, which reportedly impacted soil only. The release was identified during soil sampling prior to UST replacement at the adjoining property on July 22 and 23, 1991. Tank removal and sampling activities was overseen by City of Orange Fire Department and samples collected from the pump island areas were the reportedly the most contaminated. A series of site assessments consisting of drilling nine borings to depths of 30 and 35 feet bgs were conducted at the site. Two of the borings were converted to vapor wells and VEW-1 was screened from 5 to 55 bgs in the area of the former tank and the other vapor well, VEW-2 was screened from 5 to 15 feet bgs and 35 to 65 feet bgs in the most northern pump island area. A vapor extraction system reportedly operated at the site for six months with approximately 5,251 lbs of hydrocarbons removed from the subsurface. Following the completion of vapor extraction activities, three confirmation borings were drilled at the site. Two borings extending to 40 feet bgs were drilled in the former tank excavation and one 75 foo t boring (MBE-1) was drilled in the northern pump island area. The soil sample results for the shallow borings were all non-detect for total petroleum hydrocarbons (TPH), benzene, toluene, ethylbenzene and xylene (BTEX) and MTBE. High levels of soil contamination wer e detected in the 55- and 60-foot samples collected from MBE-1. The 60-foot sample showed 30 parts per million (ppm) of benzene and less than 200 ppm MTBE. The three five-foot interval samples beneath it were non-detect for benzene and Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 22 MTBE. However, since a thirty-foot clean zone and the lateral extent of the contamination was not delineated, four more verification borings (CB-1 through CB-4) extending to depths ranging between 94.5 and 99.5 feet bgs were drilled in the MBE-1 area. Boring CB-2, drilled adjacent to MBE-1, had all non-detect or below MCL results, except for the 59.5’ sample th at had 3.1 ppm benzene, 20 ppm toluene, 27 ppm ethylbenzene, 160 ppm xylenes and 2.3 ppm MTBE when analyzed by EPA Method 802 IB and non-detect for MTBE when analyzed by EPA Method 8260B. Eight samples collected from beneath the dispenser area to the depth of 99.5 bgs had all non- detect results except for .012 ppm toluene and .019 ppm xylenes at 94.5 feet bgs. A third boring, CB-3, located approximately 20 feet to the south of MBE-1 also had high contaminant concentrations at 61 feet bgs. The MTBE concentration of 59 ppm was detected by method 802 IB and confirmed by EPA method 8260B with the result of ND at 0.100 ppm detection limit. The seven samples collected beneath that zone of high contamination had non-detect results for benzene and MTBE and the other contaminants were all below the MCLs. The highest MTBE concentration of .91 ppm detected by Method 8260B was at 61 bgs in boring CB-4 located 40’ to the east of boring CB-2 in the dispenser area. The next two samples collected from the same boring at 65.5 and 69.5 bgs had .023 and .032 ppm MTBE, respectively and the next five samples all had non-detect MTBE results. Based on the reported concentrations of contaminants listed above no further work was recommended for the site since source removal has been conducted at the site. The residual soil contamination is reportedly limited in extent since it is in the less permeable soil at depths between 55 and 65 feet bgs in the most northern dispenser area and does not appear to threaten the groundwater below that is estimated to be at 150 feet bgs or deeper. The responsible party is identified as Arghavan Rashidi-Fard, and regulatory closure was obtained on April 17, 2000. Based on the issuance of a regulatory closure letter, distance of the impacted soil to the subject property boundary, and the regulatory oversight/status, this listing is not expected to represent a significant environmental concern and it is unlikely that a regulatory file review for this site would alter the findings of this assessment. Based on the findings, vapor migration is not expected to represent a significant environmental concern at this time. 4.2.4 Surrounding Area Listings of Concern to Subject Property No sites of concern are identified in the regulatory database report. Based on the findings, vapor migration is not expected to represent a significant environmental concern at this time. 4.2.5 Unplottable Listings No unplottable listings are identified in the regulatory database report. A copy of the regulatory database report is included in Appendix C of this report.

BA Environmental (March 26, 2014) BA Environmental (BA) prepared this report on behalf of Festival Development Corporation. The assessment was reportedly performed in accordance with ASTM Standard E1527-13. The assessment Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 25 consisted of a site reconnaissance, interviews with knowledgeable personnel, review of historical information, a review of federal, state and local regulatory databases, and determination of RECs. At the time of the 2014 assessment, the subject property was occupied by AT&T, • According to the BA, the subject property building was reportedly constructed in 1970 and was previously developed with citrus groves. Since 1970, the subject property was developed with the existing building and has been occupied by telephone and cable related services. • BA’s review of regulatory records indicated that a 4,000-gallon diesel UST was formerly located on the subject property. This UST was reportedly installed in 1992 to power an emergency generator . On the day of BA’s site reconnaissance, the generator and UST were not observed on the subject property. • The UST and associated piping were reportedly removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The UST excavation was backfilled with stockpiled soil and supplemented with imported clean fill. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013, regarding this UST, which was provided in the Appendices of BAE’s report. • This assessment has revealed no recognized environmental conditi ons (RECs) in connection with the subject property. • This assessment has revealed a historical recognized environmental condition (HREC) in connection with the previously identified UST addressed to the satisfaction of OFD on May 30, 2013. The following items of environmental concern were noted for the subject property: • Based on the age of the subject building, asbestos containing materials may exist within the subject building; • Based on the age of the subject building, lead-based paint may exist within the subject building; and • Drums of hazardous material stored for removal from the subject site were noted not to be located in secondary containment.

PCBs in electrical equipment are controlled by United States Environmental Protection Agency regulations 40 CFR, Part 761. Under the regulations, there are three categories into which electrical equipment can be classified: 1) Less than 50 parts per million (ppm) of PCBs – “Non-PCB;” 2) 50 ppm-500 ppm – “PCB-Contaminated;” and, 3) Greater than 500 ppm – “PCB-Containing.” The manufacture, process, or distribution in commerce or use of any PCB in any manner other than in a totally enclosed manner was prohibited after July 2, 1979. The on-site reconnaissance included observations of indoor and outdoor transformers and other hydraulic equipment that may contain PCBs as tabulated below: Transformers and Hydraulic Equipment Type of Equipment Location Number PCB Containing Concern Pad-Mounted Transformers Southern portion of subject property One Unlikely N The transformers are not labeled indicating PCB content. No staining or leakage was observed in the vicinity of the transformer. Based on the good condition of the equipment and utility ownership, the transformer is not expected to represent a significant environmental concern. 6.2.5 Strong, Pungent, or Noxious Odors No strong, pungent or noxious odors were evident during the site reco nnaissance. 6.2.6 Pools of Liquid No pools of liquid were observed on the subject property during the site reconnaissance. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 29 6.2.7 Drains, Sumps, and Clarifiers No drains, sumps, or clarifiers, other than those associated with stormwater removal, were observed on the subject property during the site reconnaissance. 6.2.8 Pits, Ponds, and Lagoons No pits, ponds or lagoons were observed on the subject property. 6.2.9 Stressed Vegetation No stressed vegetation was observed on the subject property. 6.2.10 Additional Potential Environmental Hazards No additional environmental hazards, including landfill activities or radiological hazards, were observed. 6.3 Non-Scope ASTM Considerations 6.3.1 Asbestos-Containing Materials (ACMs) Asbestos is the name given to a number of naturally occurring, fibrous silicate minerals mined for their useful properties such as thermal insulation, chemical and thermal stability, and high tensile strength. The Occupational Safety and Health Administration (OSHA) regulation 29 CFR 1926.1101 requires certain construction materials to be presumed to contain asbestos, for purposes of this regulation. All thermal system insulation (TSI), surfacing material, and as phalt/vinyl flooring that are present in a building that have not been appropriately tested are “presumed asbestos-containing material” (PACM). The subject property building was constructed in 1970. A limited, visual evaluation of accessible areas for the presence of suspect ACMs at the subject property was conducted. The objective of this visual survey was to note the presence and condition of suspect ACM observed. Please refer to the table below for identified suspect ACMs: Suspect ACMs Suspe ct ACM Location Friable Yes/No Physical Condition Drywall Systems Throughout Building Interior No Good with some damaged areas Floor Tiles Throughout Building Interior No Good Floor Tile Mastic Throughout Building Interior No Good Drop-tile ceiling tiles Throughout Building Interior Yes Good with some damaged areas Stucco Throughout Building Exterior Yes Good The limited visual survey consisted of noting observable materials (materials which were readily accessible and visible during the course of the site reconnaissance) that are commonly known to potentially contain asbestos. This activity was not designed to discover all sources of suspect ACM, PACM, or asbestos at the site; or to comply with any regulations and/or laws relative to planned disturbance of building materials such as renovation or demolition, or any other regulatory purpose. Rather, it is intended to give the User an indication if significant (significant due to quantity, accessibility, or condition) potential sources of ACM or PACM are Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 30 present at the subject property. Additional sampling, assessment, and evaluation will be warranted for any other use. Partner was not provided building plans or specifications for review, which may have been useful in determining areas likely to have used ACM. According to the US EPA, ACM and PACM that is intact and in good condition can, in general, be managed safely in-place under an Operations and Maintenance (O&M) Program until removal is dictated by renovation, demolition, or deteriorating material condition. Prior to any disturbance of the construction materials within this facility, a comprehensive ACM survey is recommended. 6.3.2 Lead-Based Paint (LBP) Lead is a highly toxic metal that affects virtually every system of the body. LBP is defined as any paint, varnish, stain, or other applied coating that has 1 mg/cm2 (or 5,000 ug/g or 0.5% by weight) or more of lead. Co ngress passed the Residential Lead-Based Paint Hazard Reduction Act of 1992, also known as “Title X”, to protect families from exposure to lead from paint, dust, and soil. Under Section 1017 of Title X, intact LBP on most walls and ceilings is not considered a “hazard,” although the condition of the paint should be monitored and maintained to ensure that it does not become deteriorated. Further, Section 1018 of this law directed the Housing and Urban Development (HUD) and the US EPA to require the disclosure of known information on LBP and LBP hazards before the sale or lease of most housing built before 1978. Based on the age of the subject property building (pre-1978), there is a potential that LBP is present. Interior and exterior painted surfaces were observed in good condition and therefore not expected to represent a “hazard,” although the condition of the paint should be monitored and maintained to ensure that it does not become deteriorated. 6.3.3 Radon Radon is a colorless, odorless, naturally occurring, radioactive, inert, gaseous element formed by radioactive decay of radium (Ra) atoms. The US EPA has prepared a map to assist National, State, and local organizations to target their resources and to implement radon-resistant building codes. The map divides the country into three Radon Zones, according to the table below: EPA Radon Zones EPA Zones Average Predicted Radon Levels Potential Zone 1 Exceed 4.0 pCi/L Highest Zone 2 Between 2.0 and 4.0 pCi/L Moderate Zone 3 Less than 2.0 pCi/L Low It is important to note that the EPA has found homes with elevated levels of radon in all three zones, and the US EPA recommends site-specific testing in order to determine radon levels at a specific location. However, the map does give a valuable indication of the propensity of radon gas accumulation in structures. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 31 Radon sampling was not conducted as part of this assessment. Review of the US EPA Map of Radon Zones places the subject property in Zone 3. Based upon the radon zone classification, radon is not considered to be a significant environmental concern. 6.3.4 Lead in Drinking Water According to available information, a public water system operated by the Orange Water Department serves the subject property vicinity. The sources of public water for Orange is groundwater drawn from twelve municipal wells drilled about 1,000 feet into the Santa Ana River Aquifer. According to the Orange Water Department 2020 Annual Water Quality Report, water supplied to the subject property is in compliance with all State and Federal regulations pertaining to drinking water standards, including lead and copper. 6.3.5 Mold Molds are microscopic organis ms found virtually everywhere, indoors and outdoors. Mold will grow and multiply under the right condition s, needing only sufficient moisture (e.g., in the form of very high humidity, condensation, or water from a leaking pipe, etc.) and organic material (e.g., ceiling tile, drywall, paper, or natural fiber carpet padding). Partner observed accessible, interior areas for the subject property building for significant evidence of mold growth with the exceptions detailed in Section 1.5 of this report; however, this ESA should not be used as a mold survey or inspection. Additionally, this limited assessment was not designed to assess all areas of potential mold growth that may be affected by mold growth on the subject property. Rather, it is intended to give the client an indication as to whether or not conspicuous (based on observed areas) mold growth is present at the subject property. This evaluation did not include a review of pipe chases, mechanical systems, or areas behind enclosed walls and ceilings. No obvious indications of water damage or mold growth were observed during Partner’s visual assessment. 6.3.6 Wetlands The subject property does not appear to be a designated wetland area, based on information obtained from the United States Fish & Wildlife Service; however, a comprehensive wetlands survey would be required in order to formally determine actual wetlands on the subject property. No surface impoundments, wetlands, natural catch basins, settling ponds, or lagoons are located on the subject property. 6.4 Adjoining Property Reconnaissance The adjoining property reconnaissance consisted of observing the adjoining properties from the subject property premises. No items of environmental concern were identified on the adjoining properties during the site assessment, including hazardous substances, petroleum products, ASTs, USTs, evidence of releases, PCBs, strong or noxious odors, pools of liquids, sumps or clarifiers, pits or lagoons, stressed vegetation, or any other potential environmental hazards. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 32 7.0 VAPOR ENCROACHMENT CONDITIONS Partner conducted a limited non-intrusive vapor screening on the subject property to identify, to the extent feasible, the potential for vapor encroachment conditions (VECs) in connection with the subject property. This included consideration of chemicals of concern (COC) that may migrate as vapors into the subsurface of the subject property as a result of contaminated soil and groundwater on or near the property. This screening utilized readily available data sources previously discussed in this Phase I ESA that includes: • the physical setting of the subject property (Section 2.4), • standard historical sources for the subject property, adjoining, and surrounding area (Section 3.0), • known or potentially contaminated sites as identified from information from regulatory agencies and sites on Federal, State, tribal and local databases (Section 4.0), and • information from the site reconnaissance (Section 6.0) of the subject property and observations of the surrounding properties. The results of our data collection, reconnaissance, and analysis are tabulated below: Potential for Vapor Encroachment to Impact the Subject Property Area of Concern Likely or Known VEC to Subject Property Subject Property Existing Operations or Conditions None identified that impact the subject property Historical Uses of the Subject Property None identified that impact the subject property Adjoining Property Operations or Existing Conditions None identified that impact the subject property Historical Uses of Adjoining Properties or Nearby Properties None identified that impact the subject property Regulatory Review of sites identified on Federal, State, tribal and Local Environmental Databases which were located in the AMSD None identified that impact the subject property Based on the findings of the limited non-intrusive vapor screening, vapor intrusion is unlikely to be an issue of concern in connection with the existing structures on the subject property. As such, no further/additional assessment is recommended. Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 33 8.0 FINDINGS AND CONCLUSIONS Findings and Opinions Recognized Environmental Condition A recognized environmental condition (REC) refers to the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment. The following was identified during the course of this assessment: • Partner did not identify any RECs during the course of this assessment. Controlled Recognized Environmental Condition A controlled recognized environmental condition (CREC) refers to a REC affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations). The following was identified during the course of this assessment: • Partner did not identify any CRECs during the course of this assessment. Historical Recognized Environmental Condition A historical recognized environmental condition (HREC) refers to a previous release of hazardous substances or petroleum products affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the subject property to any controls (for example, activity and use limitations or other property use limitations). The following was identified during the course of this assessment: • Partner was provided with an ESA dated March 26, 2014 prepared by BA Environmental (BA). BA reviewed Orange Fire Department (OFD) files regarding the subject property. Records indicate that a 4,000 gallon diesel underground storage tank (UST) was formerly located on the subject property near the northeast corner of the building. This UST was reportedly installed in 1992 to power an emergency generator operated by AT&T. According to OFD files, the UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The UST excavation was backfilled with stockpiled soil and supplemented with imported clean fill. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 stating that no significant contamination has occurred and the UST removal project is closed. The Orange County Environmental Health Care Agency (OCHCA) and OFD were in concurrence that no significant soil contamination was discovered from the former UST located on the subject property. No further action was required by either agency. Based on the lack of a Phase I Environmental Site Assessment Project No. 22-367781.1 May 13, 2022 Page 34 detected leak, good condition of the removed UST, issuance of a case closure letter, the former UST removed at the subject property satisfied to the requirements of OFD and OCHCA represents a HREC. Partner opines that further evaluation of the removed UST is not warranted. Business Environmental Risk A Business Environmental Risks (BER) is a risk which can have a material environmental or environmentally driven impact on the business associated with the current or planned use of commercial real estate, not necessarily related to those environmental issues required to be investigated in this practice. The following was identified during the course of this assessment: • Due to the age of the subject proper ty building, there is a potential that asbestos-containing material (ACM) and/or lead-based paint (LBP) are present. Should these materials be replaced or removed, the identified suspect ACMs would need to be sampled to co nfirm the presence or absence of asbestos prior to any renovation or demolition activities to prevent potential exposure to workers and/or building occupants. LBP can be managed in place if adhered. Significant Data Gaps No significant data gaps affecting the ability of the Environmental Professional to identify a REC were encountered during this assessment. Conclusions and Recommendations Partner has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E1527-13 and E1527-21 of 901 East Katella Avenue, Orange, Orange County, California (the “subject property”). Any exceptions to, or deletions from, this practice are described in Section 1.5 of this report. This assessment has revealed evidence of an HREC an d BERs in connection with the subject property. Based on the conclusions of this assessment, Partner recommends the following: • In accordance with requirements by local agencies, sampling of suspect ACM and removal as needed prior to demolition of the building. LBP can be managed in place if adhered.

The term de minimis refers to having such a low or minimal risk that it is not considered to be of concern. †† Recognized Environmental Condition (REC) is defined as “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.” ††† Historical Recognized Environmental Condition (HREC) is defined as “a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).” †††† Controlled Recognized Environmental Condition (CREC) is defined as “a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).” BA Environmental iii 114040 – 901 E Katella Ave, Orange, CA ††††† An Environmental Concern is defined as any other environmental condition which BA Environmental would not identify/consider a REC, CREC or an HREC. Note 1: Hazardous materials were observed to be stored on the subject property for removal. BA Environmental observed that the 55-gallon drums of these materials were not stored in secondary containment. Note 2: Historically, one 4,000 gallon diesel UST was formerly located on the subject property. The UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 regarding this UST. Note 3: Suspect ACMs were observed on the subject site during the site reconnaissance. All building materials were observed to be in good condition, with a low potential for damage. Some friable suspect ACMs were observed on the subject property. Based on the date of construction of the subject building (constructed in 1970), there is a moderate potential for ACMs to exist within the subject building. Note 4: Suspect lead-based paint was observed on the subject site. Based on the age of the subject building (constructed in 1970), there is a moderate potential for lead-based paint to exist within the subject building. Significant Data Gap Summary Report Section Description Environmental Liens and Activity Use Limitations (AULs) No significant data gap Interviews No significant data gap Historical Site Usage No significant data gap Historical Adjacent Property Usage No significant data gap Site Reconnaissance No significant data gap Environmental Agency Files No significant data gap Environmental Database No significant data gap Findings and Conclusions BA Environmental has identified no RECs and one HREC regarding the subject property. BA Environmental has identified several environmental concerns in connection with the subject property. BA Environmental has not identified any significant data gaps in connection with the subject property. Recommendations BA Environmental recommends the following with regard to the subject property: • Any suspect ACMs should be sampled prior to any renovations or demolition. Any identified ACMs scheduled for renovation or demolition, or noted to be damaged, should be abated by a licensed ACM abatement contractor, and disposed of according to all state and local regulations; • Any suspect lead-based paint should be sampled prior to any renovations or demolition. Any identified lead-based paint scheduled for renovation or demolition, or noted to be damaged, should be abated by a licensed lead-based paint abatement contractor, and disposed of according to all state and local regulations; and • Store all hazardous materials within secondary containment.

Ave, Orange, CA PHASE I ENVIRONMENTAL SITE ASSESSMENT AT&T 901 East Katella Avenue Orange, California 92867 1.0 INTRODUCTION BA Environmental (a Division of Building Analytics) has prepared the following Phase I Environmental Site Assessment (ESA) for Festival Development Corporation. This report is regarding the subject property located at 901 E Katella Avenue in the City of Orange, California. This report was prepared in accordance with the BA Environmental Proposal and Contract (LA10205) dated March 4, 2014. The assessment was performed at the Client's request using the methods and procedures consistent with good commercial and customary practice designed to conform to acceptable industry standards. The independent conclusions represent our professional judgment based on information and data available to us during the course of this assignment. Factual information regarding operations, conditions, and test data provided by the Client or their representative has been assumed to be correct and complete. The conclusions presented are based on the data provided, observations, and conditions that existed on the date of the on-site visit. In expressing the opinions stated in this report, BA Environmental has exercised the degree of skill and care ordinarily exercised by a reasonable prudent environmental professional in the same community and in the same time frame given the same or similar facts and circumstances. Documentation and data provided by the Client, designated representatives of the Client or other interested third parties, or from the public domain, and referred to in the preparation of this assessment, have been used and referenced with the understanding that BA Environmental assumes no responsibility or liability for their accuracy. 2.0 RELIANCE All reports, both written and verbal, are for the sole use and benefit of Festival Development Corporation. This report may not be relied upon by any other person or entity without the express written permission of BA Environmental. 3.0 OBJECTIVE AND SCOPE OF WORK The purpose of the ESA is to identify, to the extent feasible, recognized environmental conditions. The identification of the presence or lack of recognized environmental conditions will “permit a user to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on CERCLA liability (hereinafter, the “landowner liability protections,” or “LLPs”); that is, the practice that constitutes “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined at 42 U.S.C. §9601(35)(B)” (ASTM E1527-13). BA Environmental 2 114040 – 901 E Katella Ave, Orange, CA This Phase I ESA meets or exceeds the general requirements of the American Society for Testing and Materials (ASTM) Standard Practice for Environmental Site Assessments E1527-13, and the United States Environmental Protection Agency All Appropriate Inquiry (AAI) Rule (as defined in the Code of Federal Regulations 40 CFR Part 312). The ASTM standard practice defines good commercial and customary practice for conducting ESAs using reasonable inquiry. The scope of services for this Phase I ESA consisted of several tasks, including: • A reconnaissance of the site and its vicinity; • Interviews with current owners and occupants of the subject property, and personnel at local government agencies; • A compilation of the property history, including the review of previous environmental reports regarding the subject property (if available); • A review of pertinent local regulatory agency files; • An agency list search of facilities with recorded environmental issues located within the radii required by ASTM E1527-13; • Tier 1 Vapor Encroachment Screen; and • A summary of our findings, conclusions and recommendations. Additional services that were provided include: • A visual survey and review of a map of designated wetlands; • A visual mold survey; • A visual asbestos survey of suspect asbestos-containing materials (ACMs); • A visual lead-based paint survey; • A review of a survey and map of radon zones; and • A review of relevant Methane Zones. The scope of this Phase I ESA is not intended to address, assess, or otherwise determine whether soil or groundwater contamination, waste emplacement, existing or threatened mold/fungus growth, asbestos-containing building materials, and/or lead-based paint actually exists at the subject property. BA Environmental considers a Tier 2 vapor encroachment screen beyond the scope of this Phase I ESA, and therefore a Tier 2 vapor encroachment screen was not conducted as part of this ESA. Additionally, this ESA does not serve as a comprehensive wetlands, mining, oil, pipeline, and/or gas well survey. Such determination would require additional surveys, comprehensive subsurface exploration and/or other sampling activities, which are beyond the scope of service for this Phase I ESA. As per ASTM Practice E1527-13, there are no deviations from, or deletions of, the general requirements of this standard practice contained in this report. This Phase I ESA has been performed by, or under the direct supervision of an “environmental professional,” as defined in ASTM E1527-13 and the EPA AAI Rules. A Phase I ESA is a non-intrusive examination. As such, it is not a full and complete assessment of all environmental conditions. Adverse conditions may exist that could not be discovered by such an assessment. No ESA can completely eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a subject property. The ESA is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions in connection with a property. The BA Environmental 3 114040 – 901 E Katella Ave, Orange, CA practices of ASTM E1527-13 recognize reasonable limits of time and cost. The term “All appropriate inquiry” does not mean an exhaustive assessment of a clean property. There is a point at which the cost of information obtained, or the time required to gather it outweighs the usefulness of the information, and in fact may interrupt or interfere with the orderly or timely completion of a property transaction. One of the purposes of ASTM E1527-13 is to identify a balance between limiting the costs and time demands inherent in performing an ESA and the reduction of uncertainty about unknown conditions resulting from additional information. BA Environmental has made every reasonable effort to discover and interpret the information and current conditions regarding the site within the time available. We will recommend prudent additional investigations, if deemed necessary. Several terms are commonly used throughout this report. For the purpose of this report, the site vicinity refers to an area within a 1-mile radius of the subject site. The term adjacent property includes those properties next to or across a street or a railroad track from the subject property. Adjoining properties are those which directly abut the subject property. Recognized environmental conditions (RECs) refers to “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.” The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies” (ASTM E1527-13). The term de minimis refers to having such a low or minimal risk that it is not considered to be of concern. “Conditions determined to be de minimis are not recognized environmental conditions” (ASTM E1527-13). A Historical REC (HREC) is defined as “a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).” If a past release of a hazardous substance or petroleum product that has occurred at the subject property and has been remediated, and the remediation has been accepted by the responsible regulatory agency (for example, as evidenced by the issuance of a no further action letter or equivalent), this condition shall be considered an HREC. Controlled Recognized Environmental Condition (CREC) is defined as “a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls).” A condition considered by the environmental professional to be a controlled recognized environmental condition shall be listed in the findings section of the Phase I Environmental Site Assessment report, and as a recognized environmental condition in the conclusions section of the Phase I Environmental Site Assessment report. BA Environmental 4 114040 – 901 E Katella Ave, Orange, CA An Environmental Concern is defined as any other environmental conditions which BA Environmental would not be identified or considered as a REC CREC or HREC. BA Environmental uses risk levels (low, moderate and high) to provide the user with a relative risk for the potential for impact to the subject property. These risk levels are qualitative only, and have no quantitative basis. 4.0 DESCRIPTION OF SUBJECT PROPERTY 4.1 Site Location and Legal Description The subject property is located at 901 E Katella Avenue on the northeast corner of North Cambridge Street and East Katella Avenue, in the City of Orange, California. The subject site is identified as APN 375-461-41. 4.2 Site Improvements The subject property is occupied by a single-story AT&T facility consisting of approximately 20,000 square feet, which is situated on an approximately 2.71-acre parcel of land. The subject property is occupied by AT&T U-verse Center. Other improvements include asphalt surface parking and landscaping. The subject building was reportedly constructed in 1970 from previously developed citrus groves. Vehicular access is from East Katella Avenue on the southern side and Cambridge Street on the western side of the subject property. Primary pedestrian access is from the southern side of the subject building. 4.3 Utilities Electric: Edison Natural Gas: Southern California Gas Company Water: City of Orange Water Division Sewer: City of Orange Storm Drain: City of Orange Solid Waste Disposal: CR&R 4.4 Drinking Water Municipal water service is supplied by the City of Orange Water Davison. According to the 2012 Water Quality Report for the City of Orange Municipal Water System, there are no MCL violations, and the drinking water supplied by this municipal supplier meets all drinking water standards. A copy of the 2012 Water Quality Report for the City of San Orange Municipal Water System is included in Appendix A. BA Environmental 5 114040 – 901 E Katella Ave, Orange, CA 4.5 Adjacent Land Use During the reconnaissance of the surrounding area within a 0.25-mile radius, BA Environmental observed that the subject site is located in an area of commercial, retail and residential properties. The adjacent properties to the subject site are as follows (Figures 1 and 2): North: Single-family residences East: A commercial retail/office building South: East Katella Avenue followed by commercial retail West: North Cambridge Street followed by a USA gasoline service station 5.0 PHYSICAL SETTINGS 5.1 Topography The property is depicted on the Orange, California Topographic Quadrangle map of the United States Geological Survey (USGS). The location of the subject site is at Latitude 33° 48’ 34.20’’ North, Longitude 117° 50’ 38.04’’ West of the Prime Meridian. The topography of the subject site slopes generally towards the west at a gradient of approximately 63 feet per mile. The elevation at the site is approximately 227 feet above mean sea level (msl). Surface drainage of the subject site generally flows towards the south. Some localized changes in surface drainage are present throughout the subject site. 5.2 Geology and Hydrogeology The subject property is located approximately three miles southwest of the Peralta Hills within the Santa Ana River drainage basin. Soil beneath the site consists of unconsolidated basin fill composed of alluvial sand, gravel and silt of Holocene age (Delta, 2009b). Sallow soils encountered in investigations in the subject vicinity primarily consisted of silty clay and gravel with lesser amounts of sand (Thrifty, 1999). The site overlies the Forebay subarea of the Coastal Plain of the Orange County Groundwater Basin. This 360 square mile coastal plain is drained primarily by the Santa Ana River (CDWR, 1975). The groundwater basin is divided into upper, middle, and lower aquifers. The regional groundwater gradient is towards the southwest. Depth to groundwater in the vicinity of the site is estimated to be approximately 175 feet bgs, although some shallow perched zones may exist (OCWD, 1992). Recharge for this basin is primarily from the Santa Ana River and Santiago Creek watersheds, and infiltration along the western foothills of the Santa Ana Mountains. Groundwater was not encountered during previous site assessments (Thrifty, 1999). A subsurface investigation conducted approximately 0.4 miles to the south of the subject site is reported to have clayey sand, silty sand and sand to a depth of at least 30 feet bgs (CRA, 2008). BA Environmental 6 114040 – 901 E Katella Ave, Orange, CA 5.3 Oil Wells and Oil Fields A review of relevant Munger oil and gas field maps and Division of Oil, Gas and Geothermal Resources (DOGGR) Regional Wildcat Map indicated that the subject site was not located within any oil or gas fields, and that no oil or natural gas wells were located on the subject site (Munger, 1993; DOGGR, 2014). 6.0 USER PROVIDED INFORMATION As stated in the ASTM E1527-13 guidelines, the “User” of the Phase I ESA is responsible to provide any or all information and records regarding environmental liens and activity and use limitations (AULs) for the subject property, unless contracted with the Consultant. The Consultant is also to be informed of any abnormal sale pricing of the subject property and any special conditions. The Consultant should also be informed of the purpose of the Phase I ESA. Unless otherwise stated, the purpose of the Phase I ESA is assumed to be in the preparation for a commercial real estate transaction. During this investigation, BA Environmental has requested from the Client any information, records, and/or knowledge of the subject property. BA Environmental also requests any past environmental reports (including but not limited to Phase I ESAs, Phase II Subsurface Investigations, Site Characterization Reports, Groundwater Monitoring Reports, Remediation Reports, Asbestos or Lead-Based Paint Surveys or Abatement Documents, Mold Surveys or Abatement Documents, and Indoor Air Quality Reports) regarding the subject property. BA Environmental has requested copies of all operating permits regarding environmental issues (i.e., generators, USTs and ASTs, wastewater discharge, hazardous materials storage and handling, hazardous waste storage and disposal and air emissions permits). BA Environmental has also requested any present or historic knowledge of environmental litigations, administrative proceedings and violations associated with hazardous materials/wastes and/or petroleum products. 6.1 Title Records BA Environmental was provided a copy of a Preliminary Title Report. A review of this Preliminary Title Report did not indicate that there were any Environmental Liens and Activity and Use Limitations (AULs) associated with the subject property. A copy of the Preliminary Title Report is included in Appendix B. 6.2 Environmental Liens and Deed Restrictions BA Environmental reviewed a copy of a Preliminary Title Report which revealed no indications of Environmental Liens or AULs associated with the subject property.

Since 1970, there have been no changes in the adjacent properties to the north of the subject site. From prior to 1938 until around until around 1970, the adjacent property to the east was occupied by citrus groves. By 1970, the adjacent property to the east of the subject site was developed by what appears to be a small storefront facing East Katella Avenue. This adjacent property was redeveloped by a retail store and office sometime prior to 1989. Since 1989, there have been no changes in the adjacent property to the east of the subject site. From prior to 1938 until around until around 1970, the adjacent properties to the south were occupied by country roads followed by citrus groves. By 1970, the adjacent properties to the south were occupied by East Katella Avenue followed by a gasoline service station. The adjacent properties to the south of the subject site remained developed as such until sometime prior to 1989. By 1989, the property was redeveloped into a retail store front. Since 1989, there have been no changes in the adjacent property to the south of the subject site. From prior to 1938 until around until around 1970, the adjacent property to the west was occupied by what appears to be a farm house and citrus groves. By 1970, the adjacent property to the west of the subject site was occupied by Cambridge Street followed by a gasoline service station. Since 1970, there have been no changes in the adjacent property to the west of the subject site. BA Environmental 9 114040 – 901 E Katella Ave, Orange, CA 8.0 SITE RECONNAISSANCE AND IMPROVEMENTS On March 12, 2014, BA Environmental performed a visual reconnaissance of the subject property located at 901 East Katella, in the City of Orange, California. Mr. Richard O’Neil of BA Environmental was escorted during the site reconnaissance by Mr. Lee Pharis, property manager for AT&T. During the site reconnaissance, BA Environmental visually assessed the subject property, exterior of the subject building, common areas, office spaces, equipment areas, and the roof. BA Environmental also visually assessed any rooms which may contain hazardous materials, any janitorial spaces, any mechanical areas, and any building maintenance shops. 8.1 Site Improvements The subject property is occupied by a single-story AT&T facility consisting of approximately 20,000 square feet, which is situated on an approximately 2.71.-acre parcel of land. The subject property is occupied by AT&T U-verse Center. Other improvements include asphalt surface parking and landscaping. 8.2 Building Construction The subject building is of concrete tilt-up panels constructed over a poured in-place concrete foundation. The roof and intermediate floors consist of steel decks covered by light weight concrete. Roofing materials consists of a built-up roofing system with rolled asphalt composition. The exterior walls are composed of predominately painted tilt-up panels. The interior walls of the buildings consist of a wall papered, and painted and unpainted dry wall over wood and steel studs. Flooring materials include resilient floor tiles, resilient floor sheeting, carpet and ceramic floor tiles. The ceilings are comprised of painted and unpainted drywall and 2’ by 2’’ suspended acoustical ceiling panels. 8.3 HVAC Systems The heating, ventilating and air conditioning (HVAC) system consists of rooftop package units. 8.4 Elevators No Elevators service the subject property. 8.5 Industrial Equipment/Manufacturing Processes During the site reconnaissance, no industrial equipment was observed on the subject site. No manufacturing processes which utilize hazardous materials or petroleum products were observed during the site visit. BA Environmental 10 114040 – 901 E Katella Ave, Orange, CA 8.6 Hazardous Materials/Waste Storage Relatively small quantities of batteries, aerosol paints and electronic components were noted to be stored in 55-gallon steel drums located on the subject property. All of these materials were contained and labeled for disposal and recycling. No evidence of any releases of materials was observed. None of the drums observed were noted to be located in secondary containment. BA Environmental recommends storing all hazardous materials within secondary containment. 8.7 Biohazards and Infectious Wastes No biohazards or infectious wastes were observed on the subject site during the site reconnaissance. 8.8 Radiologic Hazards No radiologic hazards were observed on the subject site during the site reconnaissance. 8.9 Underground Storage Tanks No evidence for the presence of on-site underground storage tanks (USTs), such as fuel dispensers, fill ports, aboveground vents or piping, was observed during the site reconnaissance. According to the California State Water Resources Control Board and the Orange County Health Care Agency (OCHCA) and the City of Orange Fire Department (OFD), USTs are not currently present at the subject site. Records indicate that a 4,000 gallon diesel UST was formerly located on the subject property. This UST was reportedly installed in 1992 to power an emergency generator located on the subject property. On the day of the site reconnaissance, the generator and UST were not observed on the subject property. The UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The UST excavation was backfilled with stockpiled soil and supplemented with imported clean fill. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 regarding this UST. A copy of the closure letter is included in Appendix H. 8.10 Aboveground Storage Tanks On the day of the site reconnaissance, no aboveground storage tanks (ASTs) were observed on the subject site. BA Environmental 11 114040 – 901 E Katella Ave, Orange, CA 8.11 Hydraulic Lifts and Equipment One hydraulic cardboard bailer was observed within an enclosure on the east side of the subject building. This equipment appeared to be in good condition with no visible evidence of leakage. No staining was observed beneath this piece of equipment. No other hydraulic lifts or equipment were observed on-site on the day of the site reconnaissance. 8.12 Generators and Emergency Power Systems No electrical generators or emergency power systems were observed on the subject site on the day of the site reconnaissance. 8.13 Wastewater Treatment Systems, Clarifiers and Interceptors No wastewater treatment systems, wastewater clarifiers or interceptors were observed on the subject site on the day of the site reconnaissance. 8.14 Pits, Ponds and Lagoons Pits, ponds and lagoons are often associated with the disposal of solid and liquid wastes, which may include hazardous materials. According to ASTM Standard E1527-13, pits, ponds and lagoons are “man-made or natural depressions in the ground surface that are likely to hold liquid or sludge containing hazardous substances or petroleum products.” Information obtained from the assessment indicated that pits, ponds and lagoons do not currently exist, or have ever existed on the subject site or any of the adjacent properties. 8.15 Septic Tanks and Cesspools Septic tanks and cesspools are often associated with the disposal of wastewater from structures that are not served by public sewer systems. Septic tanks and cesspools may be associated with hazardous materials, if such materials have been inappropriately disposed of in the past via sinks. Information obtained from the subject site reconnaissance indicated that septic tanks and cesspools do not currently exist on the subject site. Presently, the sanitary sewer discharge to the subject building is tied into the city-owned sanitary sewer system. 8.16 Distressed Vegetation and Staining Areas of vegetation (trees and shrubbery) in planters were observed to be located on the subject property. No distressed vegetation, dead vegetation or discolored vegetation was observed during the site reconnaissance. No areas of stained soil, or stained asphalt or concrete, were observed on-site during the site reconnaissance. BA Environmental 12 114040 – 901 E Katella Ave, Orange, CA 8.17 Spills, Corroded Surfaces and Odors No visible evidence of spills or ponded liquids was observed during the site reconnaissance. No corroded or degraded metal or concrete surfaces were observed. No unusual odors were detected inside or outside of the subject building on the day of the site reconnaissance. 8.18 Wells, Cisterns, Sumps and Floor Drains No evidence of the presence of cisterns, sumps, floor drains or well heads, was observed at the subject property. 8.19 Pipelines No evidence for the presence of underground pipelines used to transport petroleum products such as crude oil, gasoline, or natural gas was observed on or adjacent to the subject property. 8.20 Mines, Oil and Gas Wells, Oil Production Facilities During the site reconnaissance, no visible evidence of mine shafts, open pit mines or other mining activities were observed on the day of the site reconnaissance. No oil or natural gas wells were observed on the subject site. No evidence of oil production facilities, sumps, tank batteries, piping or refineries were observed on the day of the site reconnaissance. 8.21 Polychlorinated Biphenyls (PCBs) Federal regulations put into effect following the Toxic Substance Control Act (TSCA) require that electrical transformers be labeled to identify their PCB content. The manufacture and distribution of PCBs was banned in 1979. One pad-mounted electrical transformer (5074522) was observed on-site. The transformer appeared to be in good condition with no visible evidence of leakage. No staining was observed on the concrete pad beneath the transformer. The transformer is owned and operated by Edison. Edison is responsible for all environmental issues concerning this transformer. Several small electrical transformers were observed throughout subject building. All of the transformers appeared to be of new construction and labeled as “Dry- Type” transformers. There was no apparent staining observed on the floors beneath them. Fluorescent lighting was observed throughout the subject building. Fluorescent ballasts containing PCBs have not been manufactured since the late 1970s, and have a maximum life expectancy of 15 years. Based on the life expectancy of original light ballasts, it is expected that they have been replaced, there is a low potential for the light fixtures to contain PCBs. BA Environmental did not observe other equipment on-site likely to contain PCBs. BA Environmental 13 114040 – 901 E Katella Ave, Orange, CA 8.22 Other Environmental Concerns BA Environmental did not observe any other environmental concerns on the day of the site reconnaissance. 8.23 Trash and Waste Containment Trash dumpsters were observed on the subject property. These dumpsters were observed to contain non-hazardous paper and plastic waste, and food waste. No staining was observed on the asphalt surface beneath the dumpsters. 8.24 Stormwater Stormwater that collects on the roof is directed into roof drains, which drain to the parking lot and then either into the sanitary sewer system or to the city street. From there it drains into the city-owned storm drain system. 9.0 AGENCY CONTACTS 9.1 City of Orange Fire Department (OFD) BA Environmental reviewed OFD files regarding the subject property. Records indicate that a 4,000 gallon diesel UST was formerly located on the subject property. This UST was reportedly installed in 1992 to power an emergency generator located on the subject property. According to OFD files, the UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The UST excavation was backfilled with stockpiled soil and supplemented with imported clean fill. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 regarding this UST. The Orange County Environmental Health Care Agency and OFD were in concurrence that no significant soil contamination was discovered from the former UST located on the subject property. No further action was required by either agency. 9.2 California State Regional Water Quality Control Board (RWQCB) BA Environmental searched the RWQCB’s Geotracker database for UST Program, and Spills, Leaks, Investigations and Cleanups (SLIC) Program, files for the subject site. According to the RWQCB’s Geotracker database, no files exist for the subject property. 9.3 California State Department of Toxic Substance Control (DTSC) BA Environmental searched the ENVIROSTOR database for any files regarding contamination beneath the subject site. According to the DTSC’s ENVIROSTOR database, no files exist for the subject property. BA Environmental 14 114040 – 901 E Katella Ave, Orange, CA 9.4 South Coast Air Quality Management District (AQMD) BA Environmental searched the AQMD’s Facility Information Detail (FIND) database for AQMD records regarding air emissions permits for the subject property. According to the AQMD’s FIND database, two files exist for the subject property. These permits are in regards to former equipment located on the subject property. One 4,000 gallon diesel UST and an associated emergency generator were formerly located on the subject property. 10.0 GOVERNMENT RECORDS REVIEW Regulatory compliance is a primary element of an ESA. Failure to comply with governmental regulations can result in fines, and can expose businesses or individuals to liabilities from which the law would otherwise shield them. The presence of hazardous wastes or hazardous materials, on-site or at neighboring sites, may present certain liabilities. Environmental Data Resources, Inc. (EDR) searches over 900 federal, state and local databases nationwide to provide the most recent information regarding the hazardous materials sites within the site vicinity, and which are identified below (EDR, 2014a).

According to records a 4,000 gallon diesel UST was located on the subject property from 1992 to 2013 when it was removed under the oversight of the OFD. This site was not listed on the LUST database, indicating that there have been no reported releases. A UST closure letter was issued by the OFD on June 26, 2013 regarding this UST. BA Environmental is of the opinion there is a very low potential for environmental impact to the subject property form this former UST. A copy of the closure letter is included in Appendix H. BA Environmental 16 114040 – 901 E Katella Ave, Orange, CA 10.2 Adjacent Properties The adjacent property to the west across Cambridge Street is listed on the LUST, CA FID UST, SWEEPS UST, UST, RCRA-SQG, HIST CORTESE and HIST UST databases. This is listed under the address of 825 East Katella Avenue. Records indicate that impacted soil has been identified on this adjacent property from automotive fueling activities. This adjacent site is listed on the RCRA-SQG and FINDS databases. According to RCRA database, there have been no reported RCRA violations for the subject site. Currently this property has been issued a no further action related to investigation and corrective action regarding the identified release. No groundwater was identified to be impacted from this release. BA Environmental considers there to be a low potential for impact to the subject site from this identified release. 10.3 Site Vicinity BA Environmental reviewed the EDR database report for off-site facilities in the site vicinity which may have impacted the subject property. Sites of concern included those with known releases, facilities which use significant quantities of hazardous materials, sites with USTs, and facilities which are hydraulically up-gradient of the subject site. A review of all of the sites listed within the subject site vicinity revealed that the closest non-adjacent facility is greater than 580 feet from the subject site. Based on the distances and statuses of these facilities, there is a low potential for environmental impact due to off-site sources. 11.0 DATA GAP DISCUSSION Based on all of the historical documents available and the reconnaissance of the subject site, it appears that no significant data gaps exist. Although minor historical data gaps exist, it is BA Environmental’s opinion that these data gaps are not significant, and that during these data gaps the subject property’s use did not significantly change. BA Environmental did not identify any significant data gaps in connection with the subject property. 12.0 VAPOR ENCROACHMENT SCREEN Vapor encroachment can occur when vapor migrates into on-site subsurface soils from on-site or off-site soils and/or groundwater contaminated with petroleum hydrocarbons or other volatile organic compounds. The migration of these vapors into a building or structure can pose a health risk. To assess for the potential of vapor encroachment, ASTM created the Standard Guide for Vapor Encroachment Screening on Property Involved Real Estate Transactions, ASTM 2600-10. This Standard Guide supersedes ASTM 2600-08. The purpose of this guide is to provide practical guidance and a useful process for conducting a vapor encroachment screen (VES) on a property parcel involved in a real estate transaction in the United States of America with respect to chemicals of concern (COC) that may migrate as vapors onto a property as a result of contaminated soil and groundwater on or near the property. The VES is conducted in a two-tier process, which is as follows: Tier 1 – Initial Screening (non-invasive) Tier 2 – Site Specific Numeric Screening (non-invasive and invasive) BA Environmental 17 114040 – 901 E Katella Ave, Orange, CA Based on all of the historical documents available and the reconnaissance of the subject site, it appears that no significant data gaps exist. Although minor historical data gaps exist, it is BA Environmental’s opinion that these data gaps are not significant, and that during these data gaps the subject property’s use did not significantly change. BA Environmental did not identify any significant data gaps in connection with the subject property. 13.0 ADDITIONAL NON-ASTM SCOPE ASSESSMENT 13.1 Visual Asbestos Survey On July 12, 1989, the EPA issued a final rule banning most asbestos-containing products. In 1991, this regulation was overturned by the Fifth Circuit Court of Appeals in New Orleans. As a result of the Court's decision, the following specific asbestos-containing products remain banned: flooring felt, rollboard, and corrugated, commercial, or specialty paper. In addition, the regulation continues to ban the use of asbestos in products that have not historically contained asbestos, otherwise referred to as "new uses" of asbestos. Although the use of asbestos in the manufacture of most building materials was for the most part discontinued by 1979, some non-friable ACMs, such as roofing material and floor coverings (floor tile and mastic), were manufactured and used into the mid-1980s. Other non-friable ACMs such as mastics and coatings in which the asbestos is bound by organic binders can still be found in materials today. • Friable materials are materials which can be crumbled, pulverized, or reduced to powder by hand pressure when dry. • Non-friable materials are materials in which the fibers have been locked in by a bonding agent, coating, or binder, and may not release fibers during normal use and handling. Improper handling, such as grinding or sanding of non-friable ACMs, will render these materials friable. BA Environmental performed a visual survey of suspect friable and non-friable asbestos-containing materials (ACMs). Suspect materials observed during the site reconnaissance include some 12” by 12” floor tiles and associated mastic, floor sheeting and mastic, vinyl base molding and adhesive, drywall, joint compound, carpet mastic, mirror mastic, 2’ by 4’ suspended ceiling panels, caulking, sealant, and roofing materials. All building materials were observed to be in good condition, with a low potential for damage. Based on the date of construction of the subject building (constructed in 1970), there is a moderate potential for ACMs to exist within building materials. 13.2 Visual Mold Survey BA Environmental performed a visual mold survey in accessible areas at the subject property. BA Environmental did not assess areas not readily accessible, nor did they conduct a destructive or invasive survey. It is possible that significant fungal spore growth inside walls, insulation, attic spaces, or other areas can exist and not be visible on the finished surfaces of a building’s interior spaces. BA Environmental did not 1) perform a mold/fungi inspection, 2) perform any building material surface mold sampling, or 3) perform air sampling for mold spores at the subject property as part of this Phase I. No areas of visible mold or moist areas conducive to mold growth were observed within the interior of the building within tenant spaces during the site visit. No mold odors, BA Environmental 18 114040 – 901 E Katella Ave, Orange, CA evidence of roof leaks (such as wet walls or carpets), plumbing leaks or areas that have remained moist for extended periods of time were observed within the building during the site visit. 13.3 Visual Lead-Based Paint Survey Lead was a major ingredient in paint pigment prior to and through the 1940s. While other pigments were used in the 1950s, the use of lead in paint continued until the mid- 1970s. In 1978, the Consumer Products Safety Commission banned paint and other surface coating materials that are lead-containing. BA Environmental performed a visual lead-based paint survey in accessible areas at the subject property. All of the paint observed on-site appeared to be in good condition with no visible evidence of damage or peeling. Based on the age of the current subject building, constructed in 1970, there is a moderate potential that lead-based paint exists on the subject site. 13.4 Radon Gas Survey Radon is a radioactive gas that occurs naturally in the environment and cannot be seen, smelled or tasted. The human health effect associated with exposure to elevated levels of radon is an increased risk of developing lung cancer. The US Environmental Protection Agency (EPA) and the US Center for Disease Control are concerned about the increased risk of lung cancer developing in individuals exposed to above average levels of radon in their homes or offices. In order to address these concerns, the US EPA conducted a radon survey and presented the results for various counties in 1993. The EPA’s map of Radon Zones assigns each of the 3,141 counties in the United States to one of three zones. The zone designations were determined by assessing five factors that are known to be important indicators of radon potential: indoor radon measurements, geology, aerial radioactivity surveys, soil parameters and foundation types. The subject site falls within the designation of Zone 3. Zone 3 counties have a predicted average indoor radon screening level of less than two pico curies per liter (pCi/l) of air. According to the EPA, of the 30 sites tested within the subject site’s zip code, 100% of the 1st floor living areas tested were reported to have radon levels below 4pCi/l of air. The average radon concentration was reported to be 0.763 pCi/l of air. According to the California Radon database, 43 sites were tested in the subject site’s zip code. No sites were reported to have radon levels above 4 pCi/l of air. It is BA Environmental’s opinion, based upon these results, that there is a low potential that radon is a concern for the subject property. 13.5 Methane Zones Methane is a naturally occurring hydrocarbon produced by the breakdown of organic material which can migrate through soils and sediments. Methane gas is flammable and is considered a hazardous substance by the American Congress of Government Industrial Hygienists (ACGIH), the Department of Transportation (DOT), and the National Fire Protection Association (NFPA). According to city and state agency files, the subject site is not located within an identified methane zone. BA Environmental 19 114040 – 901 E Katella Ave, Orange, CA 13.6 Wetlands and Flood Plains During the site reconnaissance and drive-by survey of the surrounding area, BA Environmental observed no indications of wetlands. According to the Environmental Data Resources, Inc. (EDR) report, the closest wetlands per the National Wetlands Inventory (1994) is located approximately 0.25 miles north of the subject site. BA Environmental reviewed the US Fish and Wildlife (USFW) National Wetlands Inventory Wetlands Mapper website. According to the USFW, the subject site is not located within a Wetlands or Riparian environment (USFW, 2014). According to information provided in the EDR report, the subject site is not located within a 100- or 500-year flood zone per the Federal Emergency Management Agency (FEMA). According to FEMA’s National Flood Insurance Program (NFIP) Panel #0161J, the subject site is located within an Other Flood Area Zone X. This is defined as areas being outside of 0.2% annual chance floodplain (FEMA, 2014). 14.0 FINDINGS, CONCLUSIONS AND RECOMMENDATIONS BA Environmental has performed a Phase I ESA, in conformance with the scope and limitations of ASTM Practice E1527-13, regarding the AT&T building located at 901 East Katella, in the City of Orange, California. Any exceptions to, or deletions from, this practice are described in the Objective and Scope of Work section of this report. This assessment has revealed no recognized environmental conditions (RECs) in connection with the subject property. This assessment has revealed the following historical recognized environmental condition (HREC) in connection with the subject property: • Historically, one 4,000 gallon diesel UST was formerly located on the subject property. The UST and associated piping was removed from the subject property under the oversight of the OFD on May 30, 2013. During removal the UST was observed to be in good condition with no evidence of a diesel release. Soil samples collected from the excavation and pipeline trench reported no detectable concentrations of petroleum hydrocarbons. The City of Orange Fire Department, Fire Prevention Bureau issued a Closure Letter on June 26, 2013 regarding this UST. The following items of environmental concern were noted for the subject property: • Based on the age of the subject building, asbestos containing materials may exist within the subject building; • Based on the age of the subject building, lead-based paint may exist within the subject building; and • Drums of hazardous material stored for removal from the subject site were noted not to be located in secondary containment. BA Environmental recommends the following with regard to the subject property: • Any suspect ACMs should be sampled prior to any renovations or demolition. Any identified ACMs scheduled for renovation or demolition, or noted to be BA Environmental 20 114040 – 901 E Katella Ave, Orange, CA damaged, should be abated by a licensed ACM abatement contractor, and disposed of according to all state and local regulations; • Any suspect lead-based paint should be sampled prior to any renovations or demolition. Any identified lead-based paint scheduled for renovation or demolition, or noted to be damaged, should be abated by a licensed lead-based paint abatement contractor, and disposed of according to all state and local regulations; and • Store all hazardous materials within secondary containment. 15.0 LIMITATIONS 15.1 General Limitations This report contains all of the limitations inherent in the methodologies that are referred to in ASTM E1527-13. BA Environmental has made every reasonable effort to discover and interpret the information and current conditions regarding the site within the time available. This assessment has been completed under the time and cost restraints implemented by the client. There is a possibility that, even with the proper application of the methodologies outlined in ASTM E1527-13, there may exist on the subject property conditions that could not be identified within the scope of the assessment or which are not reasonably identifiable from reasonably ascertainable information. This assessment is a visual, non-intrusive investigation, and conditions may exist at the site that cannot be identified solely by visual observation. No sampling, destructive or subsurface, of any type has been conducted on-site, unless expressly stated in the Objective and Scope of Work section above. All conclusions and recommendations are based on the visual observations made on the day of the site reconnaissance. BA Environmental is not responsible for identifying any environmental issues or site conditions which may have occurred after the site reconnaissance. This assessment relied upon information obtained from the site reconnaissance and from relevant regulatory agencies. BA Environmental believes that the information contained herein is reliable. However, BA Environmental cannot guarantee the accuracy of information provided by others. This assessment has been completed in general accordance with ASTM E1527-13 and accepted practices of the environmental industry. This report is not intended to address, assess, or otherwise determine whether soil or groundwater contamination, waste emplacement, existing or threatened mold/fungus growth, asbestos-containing building materials, and/or lead-based paint actually exists at the subject property. Such determination would require comprehensive subsurface exploration and/or other sampling activities, which were beyond the scope of service for this assessment. BA Environmental considers vapor intrusion beyond the scope of this Phase I ESA, and therefore a vapor intrusion study was not conducted. Additionally, this report does not serve as a comprehensive wetlands, mining, oil, pipeline, and/or gas well survey. This report summarizes an environmental investigation conducted for the subject property. Although conditions at neighboring properties may impact the subject property and, to the extent they were identified, were included in the subject property evaluation, this report does not serve as an assessment of sites other than the subject property. BA Environmental 21 114040 – 901 E Katella Ave, Orange, CA 15.2 ASTM Limitations The innocent landowner, contiguous owner, and prospective purchaser defenses to liability under CERCLA require that a person acquiring property conduct an all appropriate inquiry with respect to the site.

APPENDICES APPENDIX A: Water Quality Report City of Orange water supplies are from various sources including groundwater, purchased water from Northern California and the Colorado River, and localwatersheds. An assessment of our drinking water sources was completed in December 2002. Water sources are considered most vulnerable to contaminationfrom those activities associated with urban industrial environments such as chemical processing, petroleum pipelines and storage, gas stations and sewercollection systems. The City of Orange carefully tests all water supply sources to assure the safety and compliance with all Drinking Water Standards. A copyof the assessment summary is available at the City of Orange Water Division, located at 189 S. Water St., or you may request a summary be sent to you bycontacting the City of Orange Water Division at (714) 288-2475.SOURCE WATER ASSESSMENTCUSTOMER SERVICE:We are committed to provide promptcourteous service to our customers. If you have questions about waterquality, pressure or other supply issues, please call (714) 288-2475 or afterregular business hours call (714) 538-1961. Questions about your billshould be directed to our utility billing office at (714) 744-2233. ONGOING WATER QUALITY PROGRAMS AND ACTIVITIES:TheCity of Orange adheres to strict regulatory standards for materials usedin our water system. Rigorous third party testing assures all materialsare approved for use in potable water systems. We also operate our ownstate-certified drinking water laboratory. With testing performed in theCity’s lab and contracted testing with other public and privatelaboratories, we are able to assure that our water supply meets orexceeds all applicable drinking water standards. In addition, our staffadministers a cross-connection control program to check that waterservice connections are protected where there is a possibility of reverseflow contaminating our water system. DISINFECTION:Water supplies are made safe to drink in severalways. All of the City’s well water sources are naturally filtered as thewater percolates through the ground removing impurities. As an addedprotection, the City chlorinates all well water pumped into thedistribution system. Other water sources require treatment at facilitiesdesigned to remove impurities and make water safe to drink. Watertreatment facilities use various forms of disinfection including chlorine,chloramines and ozone. Each, or a combination of these, may be used totreat surface water purchased by the City for delivery to our customers.All treatment methods are designed to make the water safe for humansto drink. Chloramine disinfection can be toxic to fish and otheraquatic animals and is of concern for kidney dialysis patients. Watersupplied with chloramines generally makes up about 25% to 35% ofWater Supply, Water Quality, and Related Topicsour total supply. Pet fish owners should take appropriate remedieswhen changing or adding water from the tap to fishponds or fishtanks. Dialysis patients should consult a health care professional forappropriate precautions. FIRE HYDRANTS:The City of Orange maintains high standards forwater supplies available for fire protection and is rated a Class I WaterSystem by the Insurance Services Office. We have over 4,500 publicfire hydrants located throughout our service area. Many otherhydrants are privately owned and maintained by the property owner.The City tests all public hydrants on a regular interval, usually onceeach year. It is very important that hydrants function properly and areaccessible to firefighters when emergency supplies are needed. Ifthere is a hydrant in front of your home or on your property, pleasemaintain a sufficiently clear, three-foot minimum area around thehydrant.

Turbidity is a good indicator of the effectiveness of the filtration process. Since 1990, the City of Orange has provided its water customers an annual water quality report. The federal government has adopted guidelines for water agencies to follow when communicating water quality information to consumers. The State of California tailored these guidelines and the former water quality report is now called the Consumer Confidence Report. The new format is intended to provide customers a summary of the water quality data, key definitions, and other related information. This report summarizes the quality of the water provided in 2012. It includes details about water sources, what the water contains, and how it compares to standards set by the State of California. Orange vigilantly monitors and safeguards its water supplies. We are pleased to report that your tap water met all Federal and State drinking water health standards. For more information about your water, call (714) 288-2475 and ask for Chris Costlow or Willie Kralich. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791) or find it on EPA’s website (http://water.epa.gov/drink/standards/hascience.cfm). CITY OF ORANGE WATER DIVISION CONSUMER CONFIDENCE REPORT - 2012 Orange’s water comes from two sources.The primary source is groundwater drawn from 15 municipal wells drilled about 1,000 feet into the Santa Ana River Aquifer. Well water goes directly into the distribution system, is disinfected with chlorine and meets all state regulations. The second source is water imported by the Metropolitan Water District, from the Colorado river and from northern California (San Francisco-San Joaquin Bay Delta). Metropolitan water is filtered and disinfected with chloramines. The Orange City Council meets on the second and fourth Tuesday of each month at 4:30 and 7:00 p.m. in the City Hall Council Chambers, 300 East Chapman Avenue. The community is welcome to participate in these meetings. Drinking water, including bottled water,may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (800-426-4791) or find it on the website (http://www.cdph.ca.gov/certlic/drinkingwater/Pages/ NotificationLevels.aspx). The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material. It also can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water before it is treated include: • Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife. • Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming. • Pesticides and herbicides, which may come from a variety of sources such as agriculture and residential uses. • Radioactive contaminants, which are naturally occurring. • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by- products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems. In order to ensure that tap water is safe to drink, the California Department of Public Health prescribes regulations, which limit the amount of certain contaminants in water provided by public water systems. The Department’s Food and Drug Branch regulations establish limits for contaminants in bottled water, which must provide the same protection for public health. •NA:not applicable • ND: not detected • NS:no standard • NTU: Nephelometric Turbidity Units • ppm:parts per million • ppb:parts per billion • pCi/l: picocuries per liter (a measure of radiation) • Maximum Residual Disinfectant Level (MRDL): The level of a disinfectant added for water treatment that may not be exceeded at the consumer’s tap. • Maximum Residual Disinfectant Level Goal (MRDLG): The level of a disinfectant added for water treatment below which there is no known or expected risk to health. MRDLGs are set by the U.S. Environmental Protection Agency. WATER QUALITY DATA The table below lists all the drinking water contaminants detected by the City of Orange during the 2012 calendar year. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done January 1 through December 31, 2012. The State requires the City of Orange to monitor for certain contaminants less than once per year because the concentrations of these contaminants is not expected to vary significantly from year to year. Some of the data, though representative of the water quality, is more than one year old. Terms and abbreviations used below: • Primary Drinking Water Standard or PDWS:MCLs and MRLDs for contaminants that effect health along with their monitoring and reporting requirements, and water treatment requirements. • Public Health Goal (PHG): The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency. • Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs are set by the U.S. Environmental Protection Agency. • Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water. • Regulatory Action Level (AL):The concentration of a contaminant which, when exceeded, triggers treatment or other requirements that a water system must follow. • Treatment Technique (TT):A required process intended to reduce the level of a contaminant in drinking water.

An assessment of our drinking water sources was completed in December 2002. Water sources are considered most vulnerable to contaminationfrom those activities associated with urban industrial environments such as chemical processing, petroleum pipelines and storage, gas stations and sewercollection systems. The City of Orange carefully tests all water supply sources to assure the safety and compliance with all Drinking Water Standards. A copyof the assessment summary is available at the City of Orange Water Division, located at 189 S. Water St., or you may request a summary be sent to you bycontacting the City of Orange Water Division at (714) 288-2475.SOURCE WATER ASSESSMENTCUSTOMER SERVICE:We are committed to provide promptcourteous service to our customers.

ONGOING WATER QUALITY PROGRAMS AND ACTIVITIES:TheCity of Orange adheres to strict regulatory standards for materials usedin our water system. Rigorous third party testing assures all materialsare approved for use in potable water systems. We also operate our ownstate-certified drinking water laboratory. With testing performed in theCity’s lab and contracted testing with other public and privatelaboratories, we are able to assure that our water supply meets orexceeds all applicable drinking water standards. In addition, our staffadministers a cross-connection control program to check that waterservice connections are protected where there is a possibility of reverseflow contaminating our water system. DISINFECTION:Water supplies are made safe to drink in severalways. All of the City’s well water sources are naturally filtered as thewater percolates through the ground removing impurities. As an addedprotection, the City chlorinates all well water pumped into thedistribution system. Other water sources require treatment at facilitiesdesigned to remove impurities and make water safe to drink. Watertreatment facilities use various forms of disinfection including chlorine,chloramines and ozone. Each, or a combination of these, may be used totreat surface water purchased by the City for delivery to our customers.All treatment methods are designed to make the water safe for humansto drink. Chloramine disinfection can be toxic to fish and otheraquatic animals and is of concern for kidney dialysis patients. Watersupplied with chloramines generally makes up about 25% to 35% ofWater Supply, Water Quality, and Related Topicsour total supply. Pet fish owners should take appropriate remedieswhen changing or adding water from the tap to fishponds or fishtanks. Dialysis patients should consult a health care professional forappropriate precautions. FIRE HYDRANTS:The City of Orange maintains high standards forwater supplies available for fire protection and is rated a Class I WaterSystem by the Insurance Services Office. We have over 4,500 publicfire hydrants located throughout our service area. Many otherhydrants are privately owned and maintained by the property owner.The City tests all public hydrants on a regular interval, usually onceeach year. It is very important that hydrants function properly and areaccessible to firefighters when emergency supplies are needed. Ifthere is a hydrant in front of your home or on your property, pleasemaintain a sufficiently clear, three-foot minimum area around thehydrant. Bushes, shrubs, trees, etc. should be trimmed to keep thehydrant visible and accessible.REGIONAL WATER SUPPLY SOURCES:Water supplies throughoutSouthern California are derived from several sources. These sourcesinclude water from Northern California via the State Water Project, theColorado River, local groundwater basins, local water sheds,reclamation and water reuse projects, and ocean desalinization. Thecombination of some or all of these sources is available to the City ofOrange now or in the future. Reliable water supplies are essential toour health, safety, and welfare. No single source is sufficient to meetall of our water supply needs. The challenge is to find a cost-effective, reliable combination that will ensure adequate watersupplies now and into the future.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis. STANDARD ENVIRONMENTAL RECORDS Federal RCRA generators list RCRA-SQG: RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. A review of the RCRA-SQG list, as provided by EDR, and dated 09/10/2013 has revealed that there are 2 RCRA-SQG sites within approximately 0.25 miles of the target property.

The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites. A review of the ENVIROSTOR list, as provided by EDR, and dated 11/06/2013 has revealed that there are 8 ENVIROSTOR sites within approximately 1 mile of the target property.

EDR’s review was limited to those categories of sources that might, in EDR’s opinion, include gas station/filling station/service station establishments. The categories reviewed included, but were not limited to gas, gas station, gasoline station, filling station, auto, automobile repair, auto service station, service station, etc. This database falls within a category of information EDR classifies as "High Risk Historical Records", or HRHR. EDR’s HRHR effort presents unique and sometimes proprietary data about past sites and operations that typically create environmental concerns, but may not show up in current government records searches. A review of the EDR US Hist Auto Stat list, as provided by EDR, has revealed that there are 6 EDR US Hist Auto Stat sites within approximately 0.25 miles of the target property.

Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

A soil map in a soil survey is a representation of soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO) soil survey maps. SSURGO: Soil Survey Geographic Database Source: Department of Agriculture, Natural Resources Conservation Services (NRCS) Telephone: 800-672-5559 SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mapping scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to construct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates the original soil survey maps. This level of mapping is designed for use by landowners, townships and county natural resource planning and management.

The facility is located at 820 North Cypress Street in Orange, in an industrial area along the east side of the Metrolink's Inland Empire, Orange County Rail Line. The site consists of an approximately 37,000 square foot parcel of land developed with two tilt up concrete structures. Quality Aluminum Forge is a generator of hazardous waste and was authorized to treat hazardous waste onsite under Tiered Permitting Permit by Rule (PBR) on August 2, 1993. In compliance with the PBR requirements, a Phase I Environmental Assessment Checklist (Phase I Checklist) dated December 3, 2018 was submitted to DTSC. The Phase I Checklist certifies that further investigation is not necessary to determine the existence, nature, and/or extent of contamination at the facility. The California Reporting System database identifies the following onsite treatment at the QAF facility: • CESW - rinsing/treating empty containers 100 gallons or less • PBR Unit 1s and 2- treatment of wastewater by pH adjustment, precipitation and phase I separation by filtration, and gravity settling On December 26, 2018, a fire incident occurred at the site. The firefighting activities and damage from the fire itself caused a release of hydraulic oil beyond the walls of the press building onto the western adjacent property owned by the Metropolitan Transportation Authority (MTA), and Metrolink's Inland Empire-Orange County Rail Line. The MTA property is unpaved, and the hydraulic oil stained the soil. In July 2019, QAF submitted the application for corrective action oversight to the Orange County Health Care Agency, Certified Unified Program Agency (CUPA). On August 30, 2019, Orange County CUPA notified DTSC and the RWQCB of the proposed oversight under SB 1248. The notification included a copy of Murex's Hydraulic Oil Spill Investigation Report and Excavation Workplan dated July 25, 2019. The document identified soil sampling results with detection of TPH motor oil with concentration ranging from non-detect to 32,000 mg/kg. The soil samples were collected from Metrolink RR Row, outside of the QAF facility. QAF intends to do additional soil investigation and excavation. The RWQCB indicated that there was no objection for the CUPA to be the lead agency. However, due to QAF having a Tiered Permitting PBR authorization, and since the CUPA has not been delegated with corrective action authority, DTSC informed the CUPA and the RWQCB of DTSC's corrective action authority at PBR facilities and requested to have the responsible party contact DTSC for oversight. On October 17, 2019, DTSC staff conducted a site visit to verify the information on the Phase I Environmental Checklist, and the status of the stained soil from the hydraulic oil spill. Based on the site visit, DTSC found and identified an area of concern needing further investigation. DTSC also informed the QAF representatives that the remedial action oversight resulting from the hydraulic oil spill can be separated and from the PBR area of concern, at which oversight can be requested from orange County CUPA. DTSC informed orange County CUPA that they can be the lead in overseeing the investigation/remediation of the hydraulic oil spill previously identified under SB 1248 notification.

From the 1960s until 1984 Somerfield Printing operated on the site. Prior to 1960, the property was vacant. From 1984 until approximately 2003, the site was operated by Plate Corp., a plating company. From 2003 until March 2007, the property operated as Impressions Polishing and Plating, Inc.; currently the building located on the property is vacant and empty. In September 2007, the Federal Environmental Protection Agency (EPA) conducted an assessment of metal contamination on the property. Most results showed low levels of metals, but elevated levels of Nickel and Chromium III and VI were found. A consultant for the owner claims to have remediated all contamination at the site. He then covered the salt with fresh concrete. However, he did this remediation without DTSC's oversight. DTSC said that the owner had to perform two rounds of indoor air sampling, 6 months apart. The owner performed the first round of indoor air sampling. However before the second round was to be performed, the consultant found out that the owner had rented out space to a spray paint operator. Therefore, the only alternative was then soil vapor sampling. The soil vapor sampling showed that the site met the criteria for commercial and industrial use.

The extent of historical information varies with each database and current information is determined by what is publicly available to ERIS at the time of update. ERIS updates databases as set out in ASTM Standard E1527-13 and E1527-21, Section 8.1.8 Sources of Standard Source Information: "Government information from nongovernmental sources may be considered current if the source updates the information at least every 90 days, or, for information that is updated less frequently than quarterly by the government agency, within 90 days of the date the government agency makes the information available to the public." Standard Environmental Record Sources Federal Formerly Utilized Sites Remedial Action Program:rr-DOE FUSRAP-bb The U.S. Department of Energy (DOE) established the Formerly Utilized Sites Remedial Action Program (FUSRAP) in 1974 to remediate sites where radioactive contamination remained from the Manhattan Project and early U.S. Atomic Energy Commission (AEC) operations. The DOE Office of Legacy Management (LM) established long-term surveillance and maintenance (LTS&M) requirements for remediated FUSRAP sites. DOE evaluates the final site conditions of a remediated site on the basis of risk for different future uses. DOE then confirms that LTS&M requirements will maintain protectiveness. Government Publication Date: Mar 4, 2017 National Priority List:rr-NPL-bb Sites on the United States Environmental Protection Agency (EPA)'s National Priorities List of the most serious uncontrolled or abandoned hazardous waste sites identified for possible long-term remedial action under the Superfund program. The NPL, which EPA is required to update at least once a year, is based primarily on the score a site receives from EPA's Hazard Ranking System. A site must be on the NPL to receive money from the Superfund Trust Fund for remedial action. Sites are represented by boundaries where available in the EPA Superfund Site Boundaries maintained by the Shared Enterprise Geodata and Services (SEGS). Site boundaries represent the footprint of a whole site, the sum of all of the Operable Units and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary. Where there is no polygon boundary data available for a given site, the site is represented as a point. Government Publication Date: Jan 25, 2022 National Priority List - Proposed:rr-PROPOSED NPL-bb Sites proposed - by the EPA, the state agency, or concerned citizens - for addition to the NPL due to contamination by hazardous waste and identified by the Environmental Protection Agency (EPA) as a candidate for cleanup because it poses a risk to human health and/or the environment. Sites are represented by boundaries where available in the EPA Superfund Site Boundaries maintained by the Shared Enterprise Geodata and Services (SEGS). Site boundaries represent the footprint of a whole site, the sum of all of the Operable Units and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary. Where there is no polygon boundary data available for a given site, the site is represented as a point. Government Publication Date: Jan 25, 2022 Deleted NPL:rr-DELETED NPL-bb Sites deleted from the United States Environmental Protection Agency (EPA)'s National Priorities List. The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes the criteria that the EPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425.(e), sites may be deleted from the NPL where no further response is appropriate. Sites are represented by boundaries where available in the EPA Superfund Site Boundaries maintained by the Shared Enterprise Geodata and Services (SEGS). Site boundaries represent the footprint of a whole site, the sum of all of the Operable Units and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary. Where there is no polygon boundary data available for a given site, the site is represented as a point. Government Publication Date: Jan 25, 2022 DOE FUSRAP NPL PROPOSED NPL DELETED NPL Appendix: Database Descriptions 207 erisinfo.com | Environmental Risk Information Services Order No: 22042800410 SEMS List 8R Active Site Inventory:rr-SEMS-bb The Superfund Program has deployed the Superfund Enterprise Management System (SEMS), which integrates multiple legacy systems into a comprehensive tracking and reporting tool. This inventory contains active sites evaluated by the Superfund program that are either proposed to be or are on the National Priorities List (NPL) as well as sites that are in the screening and assessment phase for possible inclusion on the NPL. The Active Site Inventory Report displays site and location information at active SEMS sites. An active site is one at which site assessment, removal, remedial, enforcement, cost recovery, or oversight activities are being planned or conducted. Government Publication Date: Feb 24, 2022 Inventory of Open Dumps, June 1985:rr-ODI-bb The Resource Conservation and Recovery Act (RCRA) provides for publication of an inventory of open dumps. The Act defines "open dumps" as facilities which do not comply with EPA's "Criteria for Classification of Solid Waste Disposal Facilities and Practices" (40 CFR 257). Government Publication Date: Jun 1985 SEMS List 8R Archive Sites:rr-SEMS ARCHIVE-bb The Superfund Enterprise Management System (SEMS) Archived Site Inventory displays site and location information at sites archived from SEMS. An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program at this time. Government Publication Date: Feb 24, 2022 Comprehensive Environmental Response, Compensation and Liability Information System - CERCLIS: rr-CERCLIS-bb Superfund is a program administered by the United States Environmental Protection Agency (EPA) to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. CERCLIS is a database of potential and confirmed hazardous waste sites at which the EPA Superfund program has some involvement. It contains sites that are either proposed to be or are on the National Priorities List (NPL) as well as sites that are in the screening and assessment phase for possible inclusion on the NPL. The EPA administers the Superfund program in cooperation with individual states and tribal governments; this database is made available by the EPA. Government Publication Date: Oct 25, 2013 EPA Report on the Status of Open Dumps on Indian Lands:rr-IODI-bb Public Law 103-399, The Indian Lands Open Dump Cleanup Act of 1994, enacted October 22, 1994, identified congressional concerns that solid waste open dump sites located on American Indian or Alaska Native (AI/AN) lands threaten the health and safety of residents of those lands and contiguous areas. The purpose of the Act is to identify the location of open dumps on Indian lands, assess the relative health and environment hazards posed by those sites, and provide financial and technical assistance to Indian tribal governments to close such dumps in compliance with Federal standards and regulations or standards promulgated by Indian Tribal governments or Alaska Native entities. Government Publication Date: Dec 31, 1998 CERCLIS - No Further Remedial Action Planned:rr-CERCLIS NFRAP-bb An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program at this time. The Archive designation means that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL). This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site. Government Publication Date: Oct 25, 2013 CERCLIS Liens:rr-CERCLIS LIENS-bb A Federal Superfund lien exists at any property where EPA has incurred Superfund costs to address contamination ("Superfund site") and has provided notice of liability to the property owner. A Federal CERCLA ("Superfund") lien can exist by operation of law at any site or property at which EPA has spent Superfund monies. This database is made available by the United States Environmental Protection Agency (EPA). Government Publication Date: Jan 30, 2014 RCRA CORRACTS-Corrective Action:rr-RCRA CORRACTS-bb RCRA Info is EPA's comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984.

Katella Avenue Orange, CA 92867 ACKNOWLEDGEMENT AND SIGNATURE PAGE This Preliminary Hydrology Study prepared by C&V Consulting, Inc. under the supervision of Ryan Bittner, P.E. _____________________________________________________________________ Ryan Bittner, PE 68167 Date C&V Consulting, Inc. PRELIMINARY HYDROLOGY STUDY TTM 19253 901 E. Katella Avenue 1 1.0 SITE DESCRIPTION: The proposed site is located at 901 E. Katella Avenue, in the City of Orange, County of Orange. The proposed development encompasses one (1) parcel consisting of approximately 2.71 gross acres. The parcel is bounded by existing commercial offices to the east, existing single family residential to the north, N. Cambridge Street to the west and existing commercial, and E. Katella Avenue and existing commercial to the south. The existing site is currently occupied by an abandoned AT&T office building in the southwest quadrant, a parking lot in the remaining three quadrants, and landscape area surrounding the site. There is an overhang, a cell phone tower, and two (2) transformers onsite east of the building. No other buildings and/ or structures are present onsite. There is an existing block wall surrounding the parking lot on all sides, except along the border with the building. The existing site is served by two (2) existing driveway approaches: one (1) on N. Cambridge Street and one (1) on E. Katella Avenue. There is a wrought iron vehicular gate at each driveway entry. There are two (2) concrete walkways that connect the building to the public sidewalk on E. Katella Avenue. Per the City of Orange Zoning Map, dated September 2020, the site is located within a Commercial Professional (C-P) zone. According to the municipal code, this zone permits “lower intensity office, general retail and service commercial business.” Per the City of Orange General Plan, revised December 2015, the proposed site would be classified as Medium Density Residential. This designation provides for “multi-family townhouses, condominiums, and apartments featuring some form of internal open space in areas with good access to major circulation routes, business districts, and public open space areas.” 2.0 PURPOSE OF STUDY: The study will estimate the amount of stormwater run-off generated from the project in the existing pre-developed and post-developed conditions. Furthermore, streets and the onsite drainage system have been designed to accommodate the design storm per the Orange County Hydrology Manual. Building finished floors have also been designed to maintain a minimum 1-foot clearance above the 100-year storm. 3.0 EXISTING CONDITIONS: The existing site is relatively flat and mostly covered by impervious asphalt pavement and a large office building. Based on the ALTA topographic information, the site elevation ranges from approximately 241.8 feet above sea level (msl) in the southeast corner to 236.3 feet in the northwest corner. Overall, the site primarily flows in the north and westerly direction toward N. Cambridge Avenue. Stormwater flow is concentrated within v-gutters at the centers of the parking lot drive aisles. The area west and south of the existing building appear to slope away from the building to the west and south toward the public right-of-way, respectively. No offsite run-on drainage or cross lot drainage is entering the site. Existing block screen walls are located onsite along the northern and eastern and portions of the site along the property lines within the project boundary. In addition, there PRELIMINARY HYDROLOGY STUDY TTM 19253 901 E. Katella Avenue 2 are an existing block walls in the rear yards of eight (8) out of the nine (9) private lots along the north property line, creating a double-wall condition. The existing offsite private walks will likely have to be protected in place. This site is located within the Santa Ana River Watershed per the Orange County Flood Control District (OCFCD) Drainage System Map No. 21. Existing stormwater runoff sheet flows in the westerly direction before entering the public right-of-way of N. Cambridge Street through an existing v-gutter at the driveway, then continues in the northly direction within the gutter of the public street. Per the OCFCD Drainage Maps, surface runoff from the site continues in the northerly direction to N. Cambridge Street then is conveyed in the catch basin directly north of the intersection with Trenton Avenue. Stormwater then enters the existing underground storm drain system and continues to the OCFCD El Modena Storm Channel, converging with the Collins Storm Channel, Santa Ana River, and ultimately discharging to the Pacific Ocean 4.0 PROPOSED CONDITIONS: The proposed project consists of (52) residential condominium units, including 2 single family detached condominium units and the rest being duplexes. There will be a 3’ right-of-way dedication along Cambridge Street to the city of Orange, which accounts for the difference in project area between the pre-developed and post-developed conditions. The entire property will be owned and maintained by the homeowner’s association (HOA). The lots include drives, parking, landscaping, walkways, and common areas. Site runoff will be conveyed through concrete v-gutters then collected by two (2) onsite catch basins and an onsite area drain system that will be routed to the proposed Biofiltration Vault treatment device prior to discharge to the public right-of-way via a stormwater sump pump system. Treated runoff and overflow will be conveyed through a proposed parkway drain to the public right-of-way of Cambridge Street. Upon entering Cambridge Street, site runoff will follow the existing historical drainage pattern. 5.0 METHODOLOGY: All drainage areas were analyzed using the County of Orange Local Drainage and Hydrology Manual and the Advanced Engineering Software (AES). The site is comprised of 3 sub-areas to satisfy the Orange County Hydrology Manual. The sub-area was analyzed for acreage, land-use, peak flow rates, and time of concentration according to the Rational Method. The percentage of pervious was calculated for the existing and proposed conditions. In accordance with the Orange County Hydrology Manual all habitable structures have a finished floor elevation to allow one foot of freeboard during the 100 -year storm event. The onsite curb opening catch basin and parkway drain have been sized to convey runoff from the 25- and 100-year storm event, respectively. Calculations supporting these sizes are located in Appendix C of this report. PRELIMINARY HYDROLOGY STUDY TTM 19253 901 E. Katella Avenue 3 6.0 RESULTS: The results from this hydrology and hydraulic analysis demonstrate the following:  The drainage design for this site meets or exceeds the requirements as described in the Orange County Hydrology Manual  Flow rates have decreased in the proposed developed condition The existing and proposed conditions peak flowrates and times of concentration are summarized in the table below. Q25 (cfs) Q100 (cfs) Tc (min)* Existing 8.58 11.17 5.48 Proposed 7.95 10.31 9.32 % Decrease -7.3% -7.7% -- * Tc values are based on the results of the 100-year storm event. Catch Basin Sizing Catch basin sizing has been analyzed for the 25-year storm event based on a sump design. Refer to Attachment C for calculations. Parkway Drain Sizing Catch basin sizing has been analyzed for the 100-year storm even. Refer to Attachment C for calculations. 100-Year Water Surface Elevation Proposed finished floors will be set at least 1’ above the 100-year water surface elevation in the proposed drive aisles. Depth of flow calculations to be provided prior to final approval. 7.0 CONCLUSION: The results from this hydrology and hydraulics study utilizing methods provided by Orange County demonstrate that the proposed condition of the site generates a decrease in site runoff compared to the existing condition of the site. Runoff will be conveyed by concrete v-gutters and an onsite area drain system, collected by two (2) onsite catch basins and routed to the proposed Biofiltration vault treatment device. The flows in excess of the 25 -year storm event will enter the stormwater sump pump which outlets onto Cambridge Street through a parkway drain. Stormwater runoff discharged from the site will match the existing historic drainage pattern. Therefore, no significant impacts are anticipated due to this proposed development on the existing downstream drainage facilities. PRELIMINARY HYDROLOGY STUDY TTM 19253 901 E.

Project Description Planning Area: 901 E Katella Ave, Orange, CA 92867 Project Size (ac): 2.71 gross acres; 2.69 net acres A 3’ R/W dedication is required along Cambridge Street to support the development, therefore the post-project calculations will reflect this within the report. Percent Change in Impermeable Surfaces: The proposed project will increase the total amount of impervious area. The current site has approximately 77% impervious. The proposed project will have approximately 87% impervious. SIC Code Not Applicable Project Description The property consists of 2.69 acres located at 901 E. Katella Avenue in the City of Orange. The project proposes to construct 52 residential units including 50 duplex residential condominium units and 2 single family detached condominium units. There will be a 3’ wide dedication to the city along the entire frontage of the property on Cambridge Street. This accounts for the difference between pre-developed site area and post developed site area. The development proposes open space areas, parking areas, walkways, and driveways. Each residential unit will have a garage parking space and additional uncovered parking. The site has two entrance/exits, one (1) on Cambridge Street and one (1) on Katella Avenue. Potential Storm Water Pollutants The proposed residential project is expected to produce: Suspended Solids, Nutrients, Pathogens, Pesticides, Oil and Grease, and Trash and Debris. WQMP for 901 E. Katella Avenue August 2022 3 Hydrologic Conditions of Concern Per the TGD Figure 3, Susceptibility Analysis of Santa Ana River dated February 2013, the project site drains to engineered facilities, therefore HCOCs do not exist. Refer to Section IV.8 for a the TGD Figure. Post Development Drainage Characteristics The proposed development has been designed utilizing two (2) Drainage Management Areas (DMA) based on the Final Grading and Drainage design. Runoff will be collected by v-gutters throughout the site and an onsite area drain system and be routed to the proposed Biofiltration Vault treatment device prior to discharge to the public right-of-way via a stormwater sump pump system. Treated runoff and overflow will be conveyed through a proposed parkway drain to the public right-of-way of Cambridge Street. . Commercial Projects Not Applicable Residential Projects The project proposes 52 residential units over approximately 2.69 acres. There are two (2) driveways on Cambridge Street and Katella Avenue that provide access to the site. The site will include 3-story duplexes and 2 & 3 Story Stacked flats. This project includes a pocket park with a tot lot near the primary entrance on Cambridge Avenue. A 6’ community wall is proposed along the east property line. Parking will be provided as 104 garage spaces and 13 uncovered spaces. Common open space areas are limited to landscaping and walkways. Site Ownership and any Easements Intracorp SW, LLC, (Owner/ Developer) will appoint a Homeowner’s Association (HOA) or Property Management Company (PMC) to manage the operation and maintenance of the property. Intracorp SW, LLC 895 Dove Street, Suite 400 Newport Beach, CA 92660 (949) 955-2370 WQMP for 901 E. Katella Avenue August 2022 4 III. Site Description Reference Location Map: Refer to Vicinity Map on Site Plan within Appendix C. Site Address: 901 E. Katella Avenue, Orange, CA 92867 Zoning: Commercial Professional (C-P) Predominant Soil type: D Pre-project percent pervious: 23% Post-project percent pervious: 13% Pre-project percent impervious: 77% Post-project percent impervious: 87% Site Characteristics The existing site at 2.71 acres is currently occupied by an abandoned office building in the southwest quadrant, a parking lot in the remaining three quadrants, and landscape area surrounding the site. There is an existing block wall surrounding the parking lot on all sides, except along the border with the building. The existing site is served by two (2) existing driveway approaches: one (1) on N. Cambridge Street and one (1) on E. Katella Avenue. There is a wrought iron vehicular gate at each driveway entry. There are two (2) concrete walkways that connect the building to the public sidewalk on E. Katella Avenue. The Precipitation Zone for this area equals 0.85” Per Rainfall Zone per Figure XVI-1 per the Orange County Technical Guidance. The site primarily flows in the north and westerly direction toward Cambridge Street. Existing stormwater runoff flows in the westerly direction before entering the public right-of-way of N. Cambridge Street through an existing v-gutter at the driveway, then continues in the northly direction within the gutter of the public street. Per the OCFCD Drainage Maps, surface runoff from the site continues in the northerly direction to N. Cambridge Street then is conveyed in the catch basin directly north of the intersection with Trenton Avenue. Stormwater then enters the existing underground storm drain system and continues to the OCFCD El Modena Storm Channel, converging with the Collins Storm Channel, Santa Ana River, and ultimately discharging to the Pacific Ocean. Watershed Characteristics Watershed: Lower Santa Ana River Downstream Receiving Waters: El Modena Channel, Collins Channel, Santa Ana River, Pacific Ocean Water Quality Impairments (if applicable): Bacteria WQMP for 901 E. Katella Avenue August 2022 5 Identify Hydromodification Susceptibility: Project site not susceptible to hydromodication concerns since all downstream waterbodies are stabilized. Refer to the Section IV.8 of this report for a copy of the TGD Appendix XVI, Figure 3 Susceptibility Analysis Map for the Santa Ana River dated February 2013. Identify Watershed Management Priorities: Not applicable WQMP for 901 E. Katella Avenue August 2022 6 IV. Best Management Practices Street/ parking lot surface runoff will be collected and conveyed via a concrete longitudinal v-gutter to a proposed Modular Wetlands System (MWS), Biofiltration vault for water quality treatment. An onsite area drain system will connect directly to the MWS Biofiltration system for treatment of landscaped areas. Treated runoff will discharge through a proposed parkway drain via stormwater sump pump system. Overflow will be conveyed through the Biofiltration system to the proposed parkway drain to the public right-of-way of Cambridge Street. The Modular Wetland System (MWS) Biofiltration vaults are designed to provide a 3- phase treatment train. Initially, when the stormwater enters the system, a trash rack, filter media and settling chamber will capture large trash/ debris and sediment in the stormwater before entering the planting media. This system is designed to treat stormwater flow horizontally. Before the stormwater enters the planting or “wetland” chamber, the runoff flows through the 2nd phase, a pre-filter cartridge which captures fines TSS, metals, nutrients and bacteria. The pre-filter chamber eliminates additional maintenance of the planting area. The wetland chamber is the 3rd phase of the system which provides final treatment through a combination of physical, chemical and biological processes. IV.1 Site Design and Drainage Characteristics Table 1 Site Design BMPs Technique Included? If no, state justification. Yes No Minimize Directly Connected Impervious Areas (DCIAs) (C-Factor Reduction) X The proposed site has been designed at minimum widths in accordance to fire and planning departments. Create Reduced or “Zero Discharge” Areas (Runoff Volume Reduction)1 X Minimize Impervious Area/Maximize Permeability (C-Factor Reduction)2 X The site has been designed to allow for the maximum pervious coverage possible in order to maximize natural permeability. Conserve Natural Areas (C-Factor Reduction) X No existing area to conserve. 1 Detention and retention areas incorporated into landscape design provide areas for retaining and detaining stormwater flows, resulting in lower runoff rates and reductions in volume due to limited infiltration and evaporation. Such Site Design BMPs may reduce the size of Treatment Control BMPs. 2 The “C Factor” is a representation of the ability of a surface to produce runoff. Surfaces that produce higher volumes of runoff are represented by higher C Factors. By incorporating more pervious, lower C Factor surfaces into a development, lower volumes of runoff will be produced. Lower volumes and rates of runoff translate directly to lowering treatment requirements. The proposed project is designed to capture the required storm water runoff volume utilizing a Modular Wetlands System (MWS), Bioinfiltration vault. WQMP for 901 E.

Proper Maintenance Practices for Your Business The Ocean Begins at Your Front Door PROJECT PREVENTION Help Prevent Ocean Pollution: Preventing water pollution at your commercial/industrial site Clean beaches and healthy creeks, rivers, bays and ocean are important to Orange County. However, many landscape and building maintenance activities can lead to water pollution if you’re not careful. Paint, chemicals, plant clippings and other materials can be blown or washed into storm drains that flow to the ocean. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never pour soap or fertilizers into the ocean, so why would you let them enter the storm drains? Follow these easy tips to help prevent water pollution. Some types of industrial facilities are required to obtain coverage under the State General Industrial Permit. For more information visit: www.swrcb.ca.gov/stormwater/industrial.html Printed on Recycled Paper Tips for Pool Maintenance Call your trash hauler to replace leaking dumpsters. Do not dump any toxic substance or liquid waste on the pavement, the ground, or near a storm drain. Even materials that seem harmless such as latex paint or biodegradable cleaners can damage the environment. Recycle paints, solvents and other materials. For more information about recycling and collection centers, visit www.oclandfills.com. Store materials indoors or under cover and away from storm drains. Use a construction and demolition recycling company to recycle lumber, paper, cardboard, metals, masonry, carpet, plastic, pipes, drywall, rocks, dirt, and green waste. For a listing of construction and demolition recycling locations in your area, visit www.ciwmb.ca.gov/recycle. Properly label materials. Familiarize employees with Material Safety Data Sheets. Landscape Maintenance Compost grass clippings, leaves, sticks and other vegetation, or dispose of it at a permitted landfill or in green waste containers. Do not dispose of these materials in the street, gutter or storm drain. Irrigate slowly and inspect the system for leaks, overspraying and runoff. Adjust automatic timers to avoid overwatering. Follow label directions for the use and disposal of fertilizers and pesticides. Do not apply pesticides or fertilizers if rain is expected within 48 hours or if wind speeds are above 5 mph. Do not spray pesticides within 100 feet of waterways. Fertilizers should be worked into the soil rather than dumped onto the surface. If fertilizer is spilled on the pavement or sidewalk, sweep it up immediately and place it back in the container. Building Maintenance Never allow washwater, sweepings or sediment to enter the storm drain. Sweep up dry spills and use cat litter, towels or similar materials to absorb wet spills. Dispose of it in the trash. If you wash your building, sidewalk or parking lot, you must contain the water. Use a shop vac to collect the water and contact your city or sanitation agency for proper disposal information. Do not let water enter the street, gutter or storm drain. Use drop cloths underneath outdoor painting, scraping, and sandblasting work, and properly dispose of materials in the trash. Use a ground cloth or oversized tub for mixing paint and cleaning tools. Use a damp mop or broom to clean floors. Cover dumpsters to keep insects, animals, rainwater and sand from entering. Keep the area around the dumpster clear of trash and debris. Do not overfill the dumpster. PROJECT PREVENTION Proper Maintenance Practices for your Business Never Dispose of Anything in the Storm Drain. •Choose an effective option. Try various types of controls first: washing bugs off plants, pruning diseased parts of plants. If you need to use pest control products, choose one that targets the problem and poses the least hazard. •Finally, it’s easier to prevent pests than to control them. Before Buying Pest Control Products •Identify the pest. •Decide if pest control products are the best control measure or if there are alternatives available. •Are integrated pest management guidelines available for this pest? •Read the product label: Is the pest listed on the label? Is it the best product for the pest? Before Mixing Your Sprayer •Read the label carefully. •Buy only enough pesticide to treat the area affected by the pest. •Check the weather and don’t apply if it’s windy or about to rain •Measure the area you’re treating. •Calculate how much spray to mix. •Wear long sleeve shirt, long pants, shoes and any other protective equipment listed on the label and follow all the label precautions. •Be prepared for spills and know how to clean them up. When You’re Ready To Spray •Mix and load spray in an area where any spilled pesticide will not be able to drain or be washed away into storm drains, ditches, streams, ponds or other bodies of water. •Mix sprayer on grass, not the sidewalk or driveway. •Mix only as much as needed. When You’re Spraying •AVOID spraying in or near storm drains, ditches, streams, and ponds! •Leave an untreated strip around these areas to protect the water. When You’re done •Never dump leftovers down any drain; Save for a future application. •Triple-rinse sprayer and apply rinsewater to treated area. •Take any old or unwanted pesticides to a Household Hazardous Waste Collection Center (714) 834-6752. With Integrated Pest Management (IPM), homeowners use common sense and nature to make it difficult for pests to survive. IPM techniques include cultural practices (such as mulching to prevent weeds), encouraging natural enemies (good bugs), and judicious use of pest control products. •First, identify your pest problem. To find the best solution, you need to pin down the problem. Consult gardening books, your county cooperative extension office or your local nursery. •Decide how much pest control is necessary. If you can live with some pest damage, you can avoid intensive pest control product treatments. Think ahead.

You Are Responsible for a Sewage Spill Caused by a Blockage or Break in Your Sewer Lines! Gre ase builds up insid e and eventually blocks sewer pipes. Grease gets into the sewer from food establishments, household drains, as well as from poorly maintained commercial grease traps and interceptors. Structure problems caused by tree roots in the lines, broken/cracked pipes, missing or broken cleanout caps or undersized sewers can cause blockages. Infiltration and inflow (I/I) impacts pipe capacity and is caused when groundwater or rainwater enters the sew e r s ystem thr o ugh pi pe defects an d ill e gal connections. Time is of the essence in dealing with sewage spills. You are required to immediately: Control and minimize the spill. Keep spills contained on private property and out of gutters, storm drains and public waterways by shutting off or not using the water. Use sandbags, dirt and/or plastic sheeting to prevent sewage from entering the storm drain system. Clear the sewer blockage. Always wear gloves and wash your hands. It is recommended that a plumbing professional be called for clearing blockages and making necessary repairs. Always notify your city sewer/public works department or public sewer district of sewage spills. If the spill enters the storm drains also notify the Health Care Agency. In addition, if it exceeds 1,000 gallons notify the Office of Emergency Services. Refer to the numbers listed in this brochure. Caution Allowing sewage from your home, business or property to discharge to a gutter or storm drain may subject you to penalties and/or out-of-pocket costs to reimburse cities or public agencies for clean-up and enforcement efforts. See Regulatory Codes & Fines section for pertinent codes and fines that apply. What to Look For You Could Be Liable Sewage spills can be a very noticeable gushing of water from a manhole or a slow water leak that may take time to be noticed. Don’t dismiss unaccounted-for wet areas. Look for: !Drain backups inside the building. !Wet ground and water leaking around manhole lids onto your street. !Leaking water from cleanouts or outside drains. !Unusual odorous wet areas: sidewalks, external walls or ground/landscape around a building. Rev 4/06 printed on recycled paper Common Causes of Sewage Spills Overflowing cleanout pipe located on private property Keep people and pets away from the affected area. Untreated sewage has high levels of disease-causing viruses and bacteria. Call your local health care agency listed on the back for more information. DTP113 Sewage spills occur when the wastewater being transported via underground pipes overflows through a manhole, cleanout or broken pipe. Sewage spills can cause health hazards, damage to homes and businesses, and threaten the environment, local waterways and beaches.

How You Can Prevent Sewage Spills A property owner's sewer pipes are called service laterals and are connected to larger local main and regional trunk lines. Service laterals run from the connection at the home to the connection with the public sewer (including the area under the street). These laterals are the responsibility of the property owner and must be maintained by the property owner. Many city agencies h a v e a d o p t e d o r di n a n c e s r e q u i r i n g maintenance of service laterals. Check with y o ur c i ty s e w er /lo c a l p u b l i c w o r k s department for more information. Operation and maintenance of local and regional sewer lines are the responsi- bility of the city sewer/public works depart- ments and public sewer districts. Preventing Grease Blockages The drain is not a dump! Recycle or dispose of grease properly and never pour grease down the drain. Homeowners should mix fats, oils and grease with absor- bent waste materials such as paper, coffee grounds, or kitty litter and place it in the trash. Wipe food scraps from plates and pans and dump them in the trash. Restaurants and commercial food service establishments should always use “Kitchen Best Management Practices.” These include: !Collecting all cooking grease and liquid oil from pots, pans and fryers in covered grease containers for recycling. !Scraping or dry-wiping excess food and grease from dishes, pots, pans and fryers into the trash. !Installing drain screens on all kitchen drains. !Having spill kits readily available for cleaning up spills. !Properly maintaining grease traps or interceptors by having them serviced regularly. Check your local city codes. !City Sewer/Public Works Departments— R e s p o n s i b l e f o r p r o t e c t i n g c i t y p r o p e r t y and streets, the local storm drain system, sewage collection system and other public areas. !P u b l i c S e w e r /S a n i t a t i o n D i s t r i c t — Responsible for collecting, treating and disposing of wastewater. !County of Orange Health Care Agency— Responsible for protecting public health by closing ocean/bay waters and may close food-service businesses if a spill poses a threat to public health. !Regional Water Quality Control Boards— Responsible for protecting State waters. !Orange Cou n ty Sto rmwat e r Progr a m— Responsible for preventing harmful pollutants from being discharged or washed by stormwater runoff into the municipal storm drain system, creeks, bays and the ocean. 2 3 1 Never put grease down garbage disposals, drains or toilets.

Printed on Recycled Paper Help Prevent Ocean Pollution: Tips for Car Wash Fund-RaisersC lean beaches and healthy creeks, rivers, bays, and ocean are important to Orange County. However, many common activities can lead to water pollution if you’re not careful. Washwater, oil and residue from car washing should not flow into the street, gutter or storm drain. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never dump soap, oil or dirty water into the ocean, so don’t let it enter the storm drains. Follow these easy tips to help prevent water pollution. The Ocean Begins at Your Front Door Before beginning your car wash fund-raiser Partner with a professional car wash and avoid the pollution that parking lot car washes can produce. Hold a meeting with all participants to explain the proper procedures that should be followed when washing cars. Remove all trash and debris from the car washing area. Select only soaps, cleaners or detergents labeled “non-toxic,” “phosphate-free,” or “biodegradable.” The safest products for the environment are vegetable-based or citrus-based soaps. However, even these soaps can be toxic for the environment, so never let any products enter the street, gutter or storm drain. Do not use acid based wheel cleaners or engine degreasers. Select a site where the washwater can soak into grass, gravel, or be diverted to nearby landscaping. This will allow the washwater to filter through the vegetation and/or soil instead of flowing directly into a storm drain. Divert the washwater to an area where the water can pool and evaporate throughout the day, or arrange to dispose of the washwater down a sanitary sewer drain. For details, refer to Factsheet IC24 Wastewater Disposal Guidelines located at www.ocwatersheds. com/StormWater/documents_bmp_ existing_development.asp#res If there is a storm drain on-site, block it with sandbags. At the end of the day, dispose of the sandbags by dumping the contents in an authorized landscaped area. During the fund-raiser Never let any trash or washwater enter the street, gutter or storm drain. Shake car mats in a trash can or vacuum them. Do not shake dirt from car mats directly onto the ground. Use a bucket of soapy water to re-soap rags or sponges throughout the day rather than adding soap directly to them. Wring sponges and washrags into buckets, not the ground. Conserve water by using a spray nozzle with an automatic shut-off. Turn off the water or kink the hose when not in use. Always empty buckets into the sanitary sewer system (e.g. sinks or toilets) or a landscaped area rather than pouring the water on concrete or asphalt. After the fund-raiser Remember to clean up. Have a volunteer walk the perimeter of the site to pick up trash and debris and dispose of it properly.

If you have other suggestions, please contact your city’s stormwater representatives or call the Orange County Stormwater Program. C lean beaches and healthy creeks, rivers, bays and ocean are important to Orange County. However, many common activities can lead to water pollution if you’re not careful. Fertilizers, pesticides and other chemicals that are left on yards or driveways can be blown or washed into storm drains that flow to the ocean. Overwatering lawns can also send materials into storm drains. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never pour gardening products into the ocean, so don’t let them enter the storm drains. Follow these easy tips to help prevent water pollution. Printed on Recycled Paper Tips for Landscape and GardeningTips for Landscape & Gardening Never allow gardening products or polluted water to enter the street, gutter or storm drain. General Landscaping Tips Protect stockpiles and materials from wind and rain by storing them under tarps or secured plastic sheeting. Prevent erosion of slopes by planting fast-growing, dense ground covering plants. These will shield and bind the soil. Plant native vegetation to reduce the amount of water, fertilizers, and pesticide applied to the landscape. Never apply pesticides or fertilizers when rain is predicted within the next 48 hours. Garden & Lawn Maintenance Do not overwater. Use irrigation practices such as drip irrigation, soaker hoses or micro spray systems. Periodically inspect and fix leaks and misdirected sprinklers. Do not rake or blow leaves, clippings or pruning waste into the street, gutter or storm drain. Instead, dispose of green waste by composting, hauling it to a permitted landfill, or recycling it through your city’s program. Use slow-release fertilizers to minimize leaching, and use organic fertilizers. Read labels and use only as directed. Do not over-apply pesticides or fertilizers. Apply to spots as needed, rather than blanketing an entire area. Store pesticides, fertilizers and other chemicals in a dry covered area to prevent exposure that may result in the deterioration of containers and packaging. Rinse empty pesticide containers and re-use rinse water as you would use the product. Do not dump rinse water down storm drains. Dispose of empty containers in the trash. When available, use non-toxic alternatives to traditional pesticides, and use pesticides specifically designed to control the pest you are targeting. For more information, visit www.ipm.ucdavis.edu. If fertilizer is spilled, sweep up the spill before irrigating. If the spill is liquid, apply an absorbent material such as cat litter, and then sweep it up and dispose of it in the trash.

For emergencies, dial 911. The tips contained in this brochure provide useful information to help prevent water pollution while using, storing and disposing of paint. If you have other suggestions, please contact your city’s stormwater representatives or call the Orange County Stormwater Program. Clean beaches and healthy creeks, rivers, bays and ocean are important to Orange County. However, many common activities such as painting can lead to water pollution if you’re not careful. Paint must be used, stored and disposed of properly to ensure that it does not enter the street, gutter or storm drain. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never dump paint into the ocean, so don’t let it enter the storm drains. Follow these easy tips to help prevent water pollution. Printed on Recycled Paper Tips for Pool Maintenance Paint can cause significant damage to our environment. Whether you hire a contractor or do it yourself, it is important to follow these simple tips when purchasing, using, cleaning, storing and disposing of paint. Purchasing Paint Measure the room or object to be painted, then buy only the amount needed. Whenever possible, use water-based paint since it usually does not require hazardous solvents such as paint thinner for cleanup. Painting Use only one brush or roller per color of paint to reduce the amount of water needed for cleaning. Place open paint containers or trays on a stable surface and in a position that is unlikely to spill. Always use a tarp under the area or object being painted to collect paint drips and contain spills. Cleaning Never clean brushes or rinse paint containers in the street, gutter or storm drain. For oil-based products, use as much of the paint on the brushes as possible. Clean brushes with thinner. To reuse thinner, pour it through a fine filter (e.g. nylon, metal gauze or filter paper) to remove solids such as leftover traces of paint. For water-based products, use as much of the paint on the brushes as possible, then rinse in the sink. Collect all paint chips and dust. Chips and dust from marine paints or paints containing lead, mercury or tributyl tin are hazardous waste. Sweep up and dispose of at a Household Hazardous Waste Collection Center (HHWCC). Storing Paint Store paint in a dry location away from the elements. Store leftover water-based paint, oil-based paint and solvents separately in original or clearly marked containers. Avoid storing paint cans directly on cement floors. The bottom of the can will rust much faster on cement. Place the lid on firmly and store the paint can upside- down to prevent air from entering. This will keep the paint usable longer. Oil-based paint is usable for up to 15 years. Water-based paint remains usable for up to 10 years. Alternatives to Disposal Use excess paint to apply another coat, for touch-ups, or to paint a closet, garage, basement or attic. Give extra paint to friends or family. Extra paint can also be donated to a local theatre group, low-income housing program or school. Take extra paint to an exchange program such as the “Stop & Swap” that allows you to drop off or pick up partially used home care products free of charge. “Stop & Swap” programs are available at most HHWCCs. For HHWCC locations and hours, call (714) 834-6752 or visit www.oclandfills.com. Disposing of Paint Never put wet paint in the trash. For water-based paint: If possible, brush the leftover paint on cardboard or newspaper. Otherwise, allow the paint to dry in the can with the lid off in a well-ventilated area protected from the elements, children and pets. Stirring the paint every few days will speed up the drying. Large quantities of extra paint should be taken to a HHWCC. Once dried, paint and painted surfaces may be disposed of in the trash. When setting a dried paint can out for trash collection, leave the lid off so the collector will see that the paint has dried. For oil-based paint: Oil-based paint is a household hazardous waste. All leftover paint should be taken to a HHWCC. Aerosol paint: Dispose of aerosol paint cans at a HHWCC. Spills Never hose down pavement or other impermeable surfaces where paint has spilled. Clean up spills immediately by using an absorbent material such as cat litter. Cat litter used to clean water-based paint spills can be disposed of in the trash. When cleaning oil-based paint spills with cat litter, it must be taken to a HHWCC.

But as our cities grow and develop, these natural wet- lands have perished under countless roads, rooftops, and parking lots. Plant A Wetland Without natural wetlands our cities are deprived of water purification, flood control, and land stability. Modular Wetlands and the MWS Linear re-establish nature’s presence and rejuvenate water ways in urban areas. MWS Linear The Modular Wetland System Linear represents a pioneering breakthrough in stormwater tech- nology as the only biofiltration system to utilize patented horizontal flow, allowing for a smaller footprint and higher treatment capacity. While most biofilters use little or no pre-treatment, the MWS Linear incorporates an advanced pre-treatment chamber that includes separation and pre- filter cartridges. In this chamber sediment and hydrocarbons are removed from runoff before it enters the biofiltration chamber, in turn reducing maintenance costs and improving performance. Parking Lots Parking lots are designed to maximize space and the MWS Linear’s 4 ft. standard planter width al- lows for easy integration into parking lot islands and other landscape medians. Mixed Use The MWS Linear can be installed as a raised plant- er to treat runoff from rooftops or patios, making it perfect for sustainable “live-work” spaces. Industrial Many states enforce strict regulations for dis- charges from industrial sites. The MWS Linear has helped various sites meet difficult EPA mandated effluent limits for dissolved metals and other pol- lutants. Residential Low to high density developments can benefit from the versatile design of the MWS Linear. The system can be used in both decentralized LID de- sign and cost-effective end-of-the-line configura- tions. Streets Street applications can be challenging due to limited space. The MWS Linear is very adaptable, and offers the smallest footprint to work around the constraints of existing utilities on retrofit pro- jects. Commercial Compared to bioretention systems, the MWS Lin- ear can treat far more area in less space - meeting treatment and volume control requirements. Applications The MWS Linear has been successfully used on numerous new construction and retrofit projects. The system’s superior versatility makes it beneficial for a wide range of stormwater and waste water applications - treating rooftops, streetscapes, parking lots, and industrial sites. More applications are available on our website: www.ModularWetlands.com/Applications • Agriculture • Reuse • Low Impact Development • Waste Water www.ModularWetlands.com Configurations The MWS Linear is the preferred biofiltration system of Civil Engineers across the country due to its versatile design. This highly versatile system has available “pipe-in” options on most models, along with built-in curb or grated inlets for simple integration into your stormdrain design. Curb Type The Curb Type configuration accepts sheet flow through a curb opening and is commonly used along road ways and parking lots. It can be used in sump or flow by conditions. Length of curb opening varies based on model and size. Grate Type The Grate Type configuration offers the same features and benefits as the Curb Type but with a grated/drop inlet above the systems pre-treatment chamber. It has the added benefit of allowing for pedestrian access over the inlet. ADA compliant grates are available to assure easy and safe access. The Grate Type can also be used in scenarios where runoff needs to be intercepted on both sides of landscape islands. Downspout Type The Downspout Type is a variation of the Vault Type and is designed to accept a vertical downspout pipe from roof top and podium areas. Some models have the option of utilizing an internal bypass, simplifying the overall design. The system can be installed as a raised planter and the exterior can be stuccoed or covered with other finishes to match the look of adjacent buildings. Vault Type The system’s patented horizontal flow biofilter is able to accept inflow pipes directly into the pre-treatment chamber, meaning the MWS Linear can be used in end-of-the-line installations. This greatly improves feasibility over typical decentralized designs that are required with other biofiltration/bioretention systems. Another benefit of the “pipe in” design is the ability to install the system downstream of underground detention systems to meet water quality volume requirements. Page 3 Cartridge Housing Pre-filter Cartridge Curb Inlet Individual Media Filters Advantages & Operation The MWS Linear is the most efficient and versatile biofiltration system on the market, and the only system with horizontal flow which improves performance, reduces footprint, and minimizes maintenance. Figure-1 and Figure-2 illustrate the invaluable benefits of horizontal flow and the multiple treatment stages. • Horizontal Flow Biofiltration • Greater Filter Surface Area • Pre-Treatment Chamber • Patented Perimeter Void Area • Flow Control • No Depressed Planter Area Separation • Trash, sediment, and debris are separated before entering the pre-filter cartridges • Designed for easy maintenance access Pre-Filter Cartridges • Over 25 ft2 of surface area per cartridge • Utilizes BioMediaGREEN filter material • Removes over 80% of TSS & 90% of hydrocarbons • Prevents pollutants that cause clogging from migrating to the biofiltration chamber Pre-Treatment1 1 2 Drain-Down Line 1 2Vertical Underdrain Manifold Featured Advantages www.ModularWetlands.com Fig. 1 Horizontal Flow • Less clogging than downward flow biofilters • Water flow is subsurface • Improves biological filtration Patented Perimeter Void Area • Vertically extends void area between the walls and the WetlandMEDIA on all four sides. • Maximizes surface area of the media for higher treatment capacity WetlandMEDIA • Contains no organics and removes phosphorus • Greater surface area and 48% void space • Maximum evapotranspiration • High ion exchange capacity and light weight Flow Control • Orifice plate controls flow of water through WetlandMEDIA to a level lower than the media’s capacity. • Extends the life of the media and improves performance Drain-Down Filter • The Drain-Down is an optional feature that completely drains the pre-treatment chamber • Water that drains from the pre-treatment chamber between storm events will be treated 2x to 3x More Surface Area Than Traditional Downward Flow Bioretention Systems.Fig. 2 - Top View Biofiltration2 Discharge3 Perimeter Voi d A r e a 3 4 3Flow Control Riser Drain-Down Line Outlet Pipe Page 5 Orientations Bypass Internal Bypass Weir (Side-by-Side Only) The Side-By-Side orientation places the pre-treat- ment and discharge chambers adjacent to one an- other allowing for integration of internal bypass. The wall between these chambers can act as a by- pass weir when flows exceed the system’s treatment capacity, thus allowing bypass from the pre-treat- ment chamber directly to the discharge chamber. External Diversion Weir Structure This traditional offline diversion method can be used with the MWS Linear in scenarios where run- off is being piped to the system. These simple and effective structures are generally configured with two outflow pipes. The first is a smaller pipe on the upstream side of the diversion weir - to divert low flows over to the MWS Linear for treatment. The second is the main pipe that receives water once the system has exceeded treatment capacity and water flows over the weir. Flow By Design This method is one in which the system is placed just upstream of a standard curb or grate inlet to intercept the first flush. Higher flows simply pass by the MWS Linear and into the standard inlet down- stream. End-To-End The End-To-End orientation places the pre-treat- ment and discharge chambers on opposite ends of the biofiltration chamber therefore minimizing the width of the system to 5 ft (outside dimension). This orientation is perfect for linear projects and street retrofits where existing utilities and sidewalks limit the amount of space available for installation. One limitation of this orientation is bypass must be ex- ternal. Side-By-Side The Side-By-Side orientation places the pre-treat- ment and discharge chamber adjacent to one an- other with the biofiltration chamber running paral- lel on either side. This minimizes the system length, providing a highly compact footprint. It has been proven useful in situations such as streets with di- rectly adjacent sidewalks, as half of the system can be placed under that sidewalk. This orientation also offers internal bypass options as discussed below. This simple yet innovative diversion trough can be installed in existing or new curb and grate inlets to divert the first flush to the MWS Linear via pipe. It works similar to a rain gutter and is installed just below the opening into the inlet. It captures the low flows and channels them over to a connecting pipe exiting out the wall of the inlet and leading to the MWS Linear. The DVERT is perfect for retrofit and green street applications that allows the MWS Lin- ear to be installed anywhere space is available. DVERT Low Flow Diversion DVERT Trough www.ModularWetlands.com Rhode Island DEM Approved Approved as an authorized BMP and noted to achieve the following minimum removal efficiencies: 85% TSS, 60% Pathogens, 30% Total Phosphorus for discharges to freshwater systems, and 30% Total Nitrogen for discharges to saltwater or tidal systems. MASTEP Evaluation The University of Massachusetts at Amherst – Water Resources Research Center, issued a technical evaluation report noting removal rates up to 84% TSS, 70% Total Phosphorus, 68.5% Total Zinc, and more. Washington State DOE Approved The MWS Linear is approved for General Use Level Designation (GULD) for Basic, En- hanced, and Phosphorus treatment at 1 gpm/ft2 loading rate. The highest performing BMP on the market for all main pollutant categories. Approvals The MWS Linear has successfully met years of challenging technical reviews and testing from some of the most prestigious and demanding agencies in the nation, and perhaps the world. DEQ Assignment The Virginia Department of Environmental Quality assigned the MWS Linear, the highest phosphorus removal rating for manufactured treatment devices to meet the new Virginia Stormwater Management Program (VSMP) Technical Criteria.

Since 2007 the MWS Linear has been field tested on nu- merous sites across the country. With it’s advanced pre-treatment chamber and innovative horizontal flow biofilter, the system is able to effectively remove pollutants through a combination of physical, chemical, and biological filtration processes. With the same biological processes found in natural wetlands, the MWS Linear harnesses natures ability to process, transform, and remove even the most harmful pollutants.

Since the MWS Linear is the only biofiltration system that can ac- cept inflow pipes several feet below the surface it can be used not only in decentralized design applications but also as a large central end-of-the-line application for maximum feasibility. Volume Based Sizing Many states require treatment of a water quality volume and do not offer the option of flow based design. The MWS Linear and its unique horizontal flow makes it the only biofilter that can be used in volume based design installed downstream of ponds, detention basins, and underground storage systems.

The structure of the system resembles pre-cast catch basin or utility vaults and is installed in a similar fashion. The system is delivered fully assembled for quick in- stallation. Generally, the structure can be unloaded and set in place in 15 minutes. Our experienced team of field technicians are available to supervise installations and provide technical support. Plant Selection Abundant plants, trees, and grasses bring value and an aesthetic benefit to any urban setting, but those in the MWS Linear do even more - they increase pollutant removal. What’s not seen, but very important, is that below grade the stormwater runoff/flow is being subjected to nature’s secret weapon: a dynamic physical, chemi- cal, and biological process working to break down and remove non-point source pollutants. The flow rate is controlled in the MWS Linear, giving the plants more “contact time” so that pollutants are more successfully decomposed, volatilized and incorporated into the biomass of The MWS Linear’s micro/macro flora and fauna. A wide range of plants are suitable for use in the MWS Linear, but selec- tions vary by location and climate. View suitable plants by selecting the list relative to your project location’s hardy zone. Please visit www.ModularWetlands.com/Plants for more information and various plant lists. Maintenance Reduce your maintenance costs, man hours, and materials with the MWS Linear. Unlike other biofiltration systems that provide no pre-treatment, the MWS Linear is a self-contained treatment train which incorporates simple and effective pre-treatment. Maintenance requirements for the biofilter itself are almost completely eliminated, as the pre-treatment chamber removes and isolates trash, sediments, and hydrocarbons. What’s left is the simple maintenance of an easily accessible pre-treatment chamber that can be cleaned by hand or with a standard vac truck. Only periodic replacement of low- cost media in the pre-filter cartridges is required for long term opera- tion and there is absolutely no need to replace expensive biofiltration media.

Incoming flows are typically filtered through a planting media (mulch, compost, soil, plants, microbes, etc.) and either infiltrated or collected by an underdrain and delivered to the storm water conveyance system. Tree box filters are an increasingly common type of proprietary biotreatment device that are installed at curb level and filled with a bioretention type soil. For low to moderate flows they operate similarly to bioretention systems and are bypassed during high flows. Tree box filters are highly adaptable solutions that can be used in all types of development and in all types of soils but are especially applicable to dense urban parking lots, street, and roadways. Feasibility Screening Considerations x Proprietary biotreatment devices that are unlined may cause incidental infiltration. Therefore, an evaluation of site conditions should be conducted to evaluate whether the BMP should include an impermeable liner to avoid infiltration into the subsurface. Opportunity Criteria x Drainage areas of 0.25 to 1.0 acres. x Land use may include commercial, residential, mixed use, institutional, and subdivisions. Proprietary biotreatment facilities may also be applied in parking lot islands, traffic circles, road shoulders, and road medians. x Must not adversely affect the level of flood protection provided by the drainage system. OC-Specific Design Criteria and Considerations □ Frequent maintenance and the use of screens and grates to keep trash out may decrease the likelihood of clogging and prevent obstruction and bypass of incoming flows. □ Consult proprietors for specific criteria concerning the design and performance. □ Proprietary biotreatment may include specific media to address pollutants of concern. However, for proprietary device to be considered a biotreatment device the media must be capable of supporting rigorous growth of vegetation. □ Proprietary systems must be acceptable to the reviewing agency. Reviewing agencies shall have the discretion to request performance information. Reviewing agencies shall have the discretion to deny the use of a proprietary BMP on the grounds of performance, maintenance considerations, or other relevant factors.

Local jurisdictions may also limit plant selection in keeping with landscaping themes. Computing Sizing Criteria for Proprietary Biotreatment Device x Proprietary biotreatment devices can be volume based or flow-based BMPs. x Volume-based proprietary devices should be sized using the Simple Design Capture Volume Sizing Method described in Appendix III.3.1 or the Capture Efficiency Method for Volume-Based, Constant Drawdown BMPs described in Appendix III.3.2. x The required design flowrate for flow-based proprietary devices should be computed using the Capture Efficiency Method for Flow-based BMPs described in Appendix III.3.3). In South Orange County, the provided ponding plus pore volume must be checked to demonstrate that it is greater than 0.75 of the remaining DCV that this BMP is designed to address. Many propretary biotreatment BMPs will not be able to meet the definition of “biofiltration” that applies in South Orange County. See Section III.7 and Worksheet SOC-1.

Sweeping and vacuuming prevents sediment from the project site from entering storm drains or receiving waters. Suitable Applications Sweeping and vacuuming are suitable anywhere sediment is tracked from the project site onto public or private paved streets and roads, typically at points of egress. Sweeping and vacuuming are also applicable during preparation of paved surfaces for final paving. Limitations Sweeping and vacuuming may not be effective when sediment is wet or when tracked soil is caked (caked soil may need to be scraped loose). Implementation  Controlling the number of points where vehicles can leave the site will allow sweeping and vacuuming efforts to be focused, and perhaps save money.  Inspect potential sediment tracking locations daily.  Visible sediment tracking should be swept or vacuumed on a daily basis.

These tend to spread the dirt rather than remove it.  If not mixed with debris or trash, consider incorporating the removed sediment back into the project Costs Rental rates for self-propelled sweepers vary depending on hopper size and duration of rental. Expect rental rates from $58/hour (3 yd3 hopper) to $88/hour (9 yd3 hopper), plus operator costs. Hourly production rates vary with the amount of area to be swept and amount of sediment. Match the hopper size to the area and expect sediment load to minimize time spent dumping. Inspection and Maintenance  Inspect BMPs in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events.  When actively in use, points of ingress and egress must be inspected daily.  When tracked or spilled sediment is observed outside the construction limits, it must be removed at least daily. More frequent removal, even continuous removal, may be required in some jurisdictions.  Be careful not to sweep up any unknown substance or any object that may be potentially hazardous.  Adjust brooms frequently; maximize efficiency of sweeping operations.  After sweeping is finished, properly dispose of sweeper wastes at an approved dumpsite.

PURPOSE AND SCOPE OF SERVICES The purpose of this study was to complete an evaluation of the existing geotechnical conditions of the project site with respect to currently anticipated site development. Services provided for this study included the following:  Research and review of available geologic and general information pertinent to the site,  Review of the geotechnical report for the property by Salem Engineering Group, Inc. (2019),  Site reconnaissance,  Site exploration consisting of the excavation, logging, and sampling of three exploratory hollow-stem auger borings and logging and percolation testing of two hollow-stem auger borings,  Collection of relatively undisturbed and bulk soil samples of the onsite materials,  Laboratory testing of the soil samples obtained from the site,  Review and evaluation of site seismicity,  Engineering analyses, and  Compilation of this updated geotechnical and infiltration report which presents our findings, conclusions, and recommendations for site development. The intent of this report is to aid in the assessment of the site for future proposed development from a geotechnical perspective. The professional opinions and geotechnical information contained in this report may need to be updated based upon our review of the final site development plans. These plans should be provided to GeoTek, Inc. (GeoTek) for review when available. 2. SITE DESCRIPTION AND PROPOSED DEVELOPMENT 2.1 SITE DESCRIPTION The subject site is located at 901 East Katella Avenue in the city of Orange, Orange County, California. The site is also identified with Orange County Assessor’s Parcel Number (APN) 375- Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 2 461-41 and consists of a roughly trapezoidal-shaped 2.71-acre property. The parcel is currently occupied by a 20,000 square foot, single-story office building and associated parking lot and other improvements. At the time of our field exploration, the building was vacant. The site has a generally flat topography with a elevations ranging from 229 feet above mean sea level (amsl) to 223 feet amsl descending to the west-southwest. Surface drainage is to the west- southwest. The site is bounded by residential properties on the north, a commercial development on the east, North Cambridge Street on the west, and East Katella Avenue on the south. The general location of the site is shown in Figure 1. The current and proposed improvements on the site are displayed on Figures 2a-b, Exploration Location Maps. 2.2 PROPOSED DEVELOPMENT According to the Conceptual Site Plan, prepared by Bassenian Lagoni Architecture and dated February 16, 2022, the property will be developed with 54 residences consisting of two (2) detached single-family dwellings and twenty-six (26) sets of paired single-family dwellings, parking and drive areas, parks, underground utilities, and other improvements. The structures are anticipated to be two to three stories, of wood-framed construction, and will utilize concrete slab-on-grade floors and shallow spread foundations. Cuts and fills to reach design grades are estimated to be minimal. Minor slopes and perimeter/retaining walls are also expected. In addition, we anticipate that stormwater at the site be managed via relatively shallow infiltration systems. Specific locations, depths, and characteristics of the BMP systems are currently unknown. If site development differs from the assumptions made herein, the recommendations included in this report should be subject to further review and evaluation. Final site development plans should be reviewed by GeoTek when they become available. Additional geotechnical field exploration, analyses and recommendations may be necessary upon review of site development plans. 3. REPORT REVIEW On May 16, 2019, Salem Geotechnical Engineering Group, Inc. (Salem) issued a geotechnical investigation report for the proposed commercial development of the project site. The investigation eight (8) exploratory borings to depths ranging from 5 to 50 feet and three (3) Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 3 borings for percolation testing to depths between 5 and 10 feet. Salem’s exploration suggested that the site is mostly underlain by medium dense/stiff to very dense/hard alluvial deposits. However, localized areas with undocumented fill up to 15 feet in thickness were also noted. No groundwater was encountered during the site investigation and the potential for liquefaction at the site was considered nil. Salem concluded that the property has surficial soils with medium expansion potential, negligible sulfate concentrations, and poor infiltration rates. The logs of the exploratory borings, percolation and infiltration test data, and results of laboratory test results by Salem are included in Appendix A. The approximate locations of Salem’s explorations are shown on the Exploration Location Maps, Figures 2a-b. 4. FIELD EXPLORATION, LABORATORY TESTING, AND PERCOLATION TESTING 4.1 FIELD EXPLORATION GeoTek evaluated the subsurface conditions of the site via three (3) exploratory borings excavated on May 5, 2022 to approximately 19 to 22.5 feet below existing grade. In addition, two (2) percolation test borings approximately five (5) feet deep were advanced within the lower portions of the site (west-southwest side) where stormwater BMP systems may be placed. The borings were drilled with a truck-mounted hollow-stem auger drill rig. The approximate locations of our site explorations and past explorations by Salem are shown on the Exploration Location Maps, Figures 2a-b. Logs of the borings are provided in Appendices A and B. 4.2 LABORATORY TESTING Laboratory testing was performed on selected relatively undisturbed and bulk soil samples collected during the field exploration. The purpose of the laboratory testing was to confirm the field classification of the soil materials encountered and to evaluate the soils physical properties for use in the engineering design and analysis. Results of the laboratory testing program along with a brief description and relevant information regarding testing procedures are included in Appendix C. 4.3 PERCOLATION TESTING Percolation testing was performed at boring locations I-1 and I-2 to assess the infiltration rates of the site soils underlying potential stormwater system areas. The borings were excavated to approximately five (5) feet below the existing grade, which was assumed to be the approximate invert depth of the infiltration systems. The boring diameter was approximately eight inches. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 4 Percolation testing was performed within the lower approximately 20 inches in the borings by a representative of our firm, in general conformance with the Boring Percolation Test Procedure outlined in the Technical Guidance Document Appendix VII (Orange County, 2013). As required, the percolation rates were corrected to account for discharge of water from both the sides and bottom of the borings. This correction was done using the Porchet Method, obtaining the infiltration rates tabulated below: SUMMARY OF RESULTS Boring Observed Infiltration Rate, Kobserved (inches per hour) Measured Infiltration Rate, Kmeasured (inches per hour) I-1 4.2 2.1 I-2 0.04 0.02 As recommended by the referenced Technical Guidance Document (Orange County, 2013), a factor of safety of 2.0 was applied to the observed (field) rates to estimate measured infiltration rates. As shown on the table above, poor to favorable infiltration rates (nil to 2 inches per hour) were encountered at the site. Salem (2019) reported relatively similar findings with variable rates ranging from nil to 0.23 inches per hour. Detailed percolation/infiltration test data is included in Appendix D. It should be noted that the infiltration rates provided above were performed in relatively undisturbed on-site soils. Infiltration rates will vary and are mostly dependent on the underlying consistency of the site soils and relative density. Infiltration rates may be impacted by weight of equipment travelling over the soils, placement of engineered fill and other various factors. GeoTek assumes no responsibility or liability for the ultimate design or performance of the storm water facility. 5. GEOLOGIC AND SOILS CONDITIONS 5.1 REGIONAL SETTING The subject property is situated in the Peninsular Ranges geomorphic province. The Peninsular Ranges province is one of the largest geomorphic units in western North America. Basically, it extends roughly 975 miles from the north and extends from the Transverse Ranges geomorphic province to the tip of Baja California, from north to south. This province varies in width from about 30 to 100 miles. It is bounded on the west by the Pacific Ocean, on the south by the Gulf of California and on the east by the Colorado Desert Province. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 5 The Peninsular Ranges are essentially a series of northwest-southeast oriented fault blocks. Several major fault zones are found in this province. The Elsinore Fault zone and the San Jacinto Fault zone trend northwest-southeast and are found in the near the middle of the province. The San Andreas Fault zone borders the northeasterly margin of the province. More specific to the subject property, Morton, D.M., and Miller, F.K., (2006) map the site to be underlain by old alluvial fan deposits (late to middle Pleistocene age). Additionally, the nearest known active fault to the site is the Elsinore fault- Whittier Section located approximately 7.6 miles to the north. 5.2 GENERAL SOIL/GEOLOGIC CONDITIONS A brief description of the earth materials encountered in our explorations and explorations by Salem (2019) is presented in the following sections. 5.2.1 Undocumented Fill Undocumented fill was encountered in the area of GeoTek’s boring B-1 and Salem’s boring B-5 beneath the existing pavement section to approximately 9 to 15 feet below grade, respectively. The fill is associated to the construction of the existing site improvements and is generally composed of brown to grayish brown, slightly moist clayey sand and poorly graded to well graded sand with silt and some fine gravel. Because of its variable in-place density (ranging from very loose to very dense) and lack of documentation regarding its placement, the fill is considered to be un-engineered, un-compacted material. 5.2.2 Old Alluvial Fan Deposits Old alluvial fan deposits were encountered in our borings and borings by Salem below the fill or existing pavement section and extended to the maximum depth explored of about 50 feet. The old alluvial fan deposits consist of interbedded units of clayey sand, silty sand, sandy clay, and poorly graded to well graded sand with silt and some fine gravel. The alluvium was reddish brown to grayish brown in color, slightly moist to moist, and in a medium dense/stiff to very dense/hard in-place state to the total depth explored, based on our field observations, blow counts, and in-place density determinations. Tests conducted on the most unfavorable units of the alluvium (selected based on blow counts) indicated a negligible to slight potential for collapse upon application of water. Test results obtained by Salem suggest similar findings. The near surface site soils were found to have “very low” to “low” expansion potential based on our laboratory test results in accordance with ASTM D 4829. However, Salem also encountered soil units with “medium” expansion potential. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 6 5.3 SURFACE WATER AND GROUNDWATER 5.3.1 Surface Water If encountered during the earthwork construction, surface water on this site is the result of precipitation or surface run-off from surrounding sites. Overall drainage in the area is variable, and most commonly directed toward the west-southwest. Provisions for surface drainage will need to be accounted for by the project civil engineer. 5.3.2 Groundwater Groundwater was not encountered in the deepest site boring, Boring B-5, excavated by Salem (2019) to a maximum depth of 50 feet. The GeoTracker database and the California Water Data Library show several groundwater wells located within 1.5 miles from the site, with a depth to groundwater in excess of 100 feet. Perched groundwater or localized seepage can occur due to variations in rainfall, irrigation practices, and other factors not evident at the time of this investigation. 5.4 FAULTING AND SEISMICITY The geologic structure of the entire southern California area is dominated mainly by northwest- trending faults associated with the San Andreas system. The site is in a seismically active region. No active or potentially active fault is known to exist at this site nor is the site situated within an “Alquist-Priolo” Earthquake Fault Zone (Bryant and Hart, 2007; CGS, 1986). The subject property is not located within a State of California Seismic Hazard Zone for earthquake induced liquefaction (CGS, 1997). The subject property is not located within a State of California Seismic Hazard Zone for earthquake induced landsliding. The nearest known active fault to the site is the Elsinore fault- Whittier Section located approximately 7.6 miles to the north. 5.4.1 Seismic Design Parameters The site is located at approximately 33.8097⁰ Latitude and -117.8437⁰ Longitude. Based on the conditions observed in the site excavations and review of regional geologic maps, a Site Class “D” appears to be the appropriate category for the property. Site spectral accelerations (Sa and S1), for 0.2 and 1.0 second periods for a Class “D” site, were determined from the SEAOC/OSHPD web interface that utilizes the USGS web services and retrieves the seismic design data and presents that information in a report format. As noted using the ASCE 7-16 option on the SEAOC/OSHPD website, the values for SM1 and SD1 are reported as “null-See Section 11.4.8 (of ASCE 7-16)”. As noted in ASCE 7-16, Section 11.4.8, a site-specific ground motion procedure is recommended for Site Class D when the value S1 exceeds 0.2. The value S1 for the subject site exceeds 0.2. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 7 For a Site Class “D”, an exception to performing a site-specific ground motion analysis is allowed in ASCE 7-16 where S1 exceeds 0.2 provided the value of the seismic response coefficient, Cs, is conservatively calculated by Eq 12.8-2 of ASCE 7-16 for values of T≤1.5Ts and taken as equal to 1.5 times the value computed in accordance with either Eq. 12.8-3 for TL≥T>1.5Ts or Eq. 12.8-4 for T>TL. Assuming that the Cs value calculated by and used by the structural engineer allows for the exclusion per ASCE 7-16, noted above, then a site-specific ground motion analysis is not required. For this assumption and condition, the following seismic design parameters, based on the 2015 National Earthquake Hazards Reduction Program (NEHRP)/ASCE 7-16, are presented on the following table: SITE SEISMIC PARAMETERS Mapped 0.2 sec Period Spectral Acceleration, Ss 1.426g Mapped 1.0 sec Period Spectral Acceleration, S1 0.507g Site Coefficient for Site Class “D,” Fa 1.0 Site Coefficient for Site Class “D,” Fv 1.793 Maximum Considered Earthquake Spectral Response Acceleration for 0.2 Second, SMS 1.426g Maximum Considered Earthquake Spectral Response Acceleration for 1.0 Second, SM1 0.908g 5% Damped Design Spectral Response Acceleration Parameter at 0.2 Second, SDS 0.951g 5% Damped Design Spectral Response Acceleration Parameter at 1 second, SD1 0.606g Site Modified Peak Ground Acceleration, PGAM 0.658g Seismic Design Category D Final selection of the appropriate seismic design coefficients should be made by the project structural engineer based upon the local practices and ordinances, expected building response and desired level of conservatism. 5.5 LIQUEFACTION AND SEISMICALLY INDUCED SETTLEMENT The project site is not located within an area mapped by the State of California for liquefaction potential. Due to the presence of dense/stiff alluvium and the lack of shallow groundwater, the risk of soil liquefaction at the site is nil. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 8 Loose to medium dense sands tend to densify during strong ground shaking. Based on the blow counts recorded in the deepest site boring (Salem’s boring B-5) and utilizing a peak ground acceleration of 0.66g and a modal magnitude weighted (Mw) seismic event of 7.72, we estimate that the seismically induced settlement of the sandy units at the site is less than 0.5 inches total settlement and less than 0.25-inches differential settlement over a 30-foot span. 5.6 OTHER SEISMIC HAZARDS Evidence of ancient landslides or slope instabilities at this site was not observed during our investigation. Thus, the potential for landslides is considered negligible. The site is located about two miles west of the Santiago Creek Recharge Basin. However, as the project site is located at a higher elevation than the basin, the potential for a seiche is considered negligible. The potential for a tsunami is also nil due to the great distance between the site and the ocean. 6. CONCLUSIONS AND RECOMMENDATIONS 6.1 GENERAL Development of the site appears feasible from a geotechnical viewpoint. The following recommendations should be incorporated into the design and construction phases of development. 6.2 EARTHWORK CONSIDERATIONS Earthwork and grading should be performed in accordance with the applicable grading ordinances of the City of Orange, the 2019 California Building Code (CBC), and recommendations contained in this report. Site grading plans should be reviewed by this office when they become available. Additional recommendations will likely be offered subsequent to review of these plans. 6.2.1 Site Clearing and Preparation Site preparation should start with demolition/razing of existing site improvements and removal of deleterious materials and vegetation. Demolition should include removal of all pavements, floor slabs, foundations, and any other below-grade construction. These materials should be properly disposed of off-site. Voids resulting from site clearing (such as removals of underground utilities, foundations, etc.) should be replaced with engineered fill materials. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 9 6.2.2 Removals Based on the boring data and the field observations, the upper three (3) to fifteen (15) feet of existing site soils or two (2) feet below footing base, whichever is deeper. should be removed in order to provide a homogeneous, dense fill mat for structural support. Deeper removals may be required in some areas to eliminate all undocumented fill and unsuitable alluvium. The bottom of removals should expose competent native alluvial soils which are defined as relatively homogeneous, no visibly porous materials with an in-place density of at least 85 percent of the soil’s maximum dry density as determined per ASTM D 1557. As a minimum, removals should extend down and away from foundation elements at a 1:1 (h:v) projection to the recommended removal depth, or a minimum of five feet laterally. The upper two feet of soil or one foot below pavement subgrade, whichever is deeper, should be removed below asphaltic concrete pavement and Portland cement concrete hardscape areas. Deeper removals may be required in areas containing loose undocumented fills. The horizontal extent of removals should extend at least two feet beyond the edge of the improvements. The bottom of all removals should be scarified to a minimum depth of 12 inches, brought to slightly above the optimum moisture content, and then recompacted to at least 90 percent of the soil’s maximum dry density (ASTM D 1557). The bottoms of removals should be observed by a GeoTek representative prior to scarification. 6.2.3 Engineered Fill The onsite soils are considered suitable for reuse as engineered fill provided they are free from vegetation, roots, and rock/concrete or hard lumps greater than six (6) inches in maximum dimension. Concrete generated from the demolition of existing site improvements may be incorporated into site fills provided the following guidelines are implemented: 1) concrete should be free of rebar or other deleterious materials and should be broken down to a maximum dimension of six (6) inches; 2) concrete should not be placed within three (3) feet of finish grade in the building pad areas or within one (1) foot of subgrade elevations in the street/drive areas; 3) concrete should be distributed in the fill and should not be “nested” or placed in concentrated pockets. The undercut areas should be brought to final pad elevations with fill materials that are placed and compacted in general accordance with minimum project standards. Fill materials should be placed at or above optimum moisture content and should be compacted to a minimum relative compaction of 90 percent as determined by ASTM Test Method D 1557. Additional recommendations pertaining to fill placement are presented in Appendix E. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 10 6.2.4 Excavation Characteristics Excavation in the onsite soil materials is expected to be easy using heavy-duty grading equipment in good operating conditions. All temporary excavations for grading purposes and installation of underground utilities should be constructed in accordance with local and Cal-OSHA guidelines. Temporary excavations within the onsite materials should be stable at 1:1 (h:v) inclinations for cuts less than ten (10) feet in height. 6.2.5 Shrinkage and Subsidence Several factors will impact earthwork balancing on the site, including shrinkage, subsidence, trench spoil from utilities and footing excavations, as well as the accuracy of topography. Shrinkage, bulking, and subsidence are primarily dependent upon the degree of compactive effort achieved during construction. For planning purposes, a shrinkage factor of 5 to 10 percent for both the existing fills and upper alluvium may be considered. Site balance areas should be available in order to adjust project grades, depending on actual field conditions at the conclusion of site earthwork construction. Bulking is not considered to be a significant factor with the underlying materials within the vicinity of the anticipated construction. Subsidence on the order of up to 0.1-foot could occur. 6.2.6 Trench Excavations and Backfill Temporary excavations within the onsite materials should be stable at 1:1 (h:v) inclinations for short durations during construction, and where cuts do not exceed ten (10) feet in height. Temporary cuts to a maximum height of four (4) feet can be excavated vertically, but local sloughing and/or failure could occur due to the granular nature of some of the onsite units. Increased caution should be applied when working near or within any excavations at this site. Trench excavations should conform to Cal-OSHA regulations. The contractor should have a competent person, per OSHA requirements, on site during construction to observe conditions and to make the appropriate recommendations. Utility trench backfill should be compacted to at least 90 percent relative compaction (as determined per ASTM D 1557). Under-slab trenches should also be compacted to project specifications. Where applicable, based on jurisdictional requirements, the top 12 inches of backfill below subgrade for road pavements should be compacted to at least 95 percent relative compaction. Much of the onsite materials may not be suitable for use as bedding material but should be suitable as backfill provided particles larger than six (6) ± inches are removed. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 11 Compaction should be achieved with a mechanical compaction device. Ponding or jetting of trench backfill is not recommended. If backfill soils have dried out, they should be thoroughly moisture conditioned prior to placement in trenches. 6.3 DESIGN RECOMMENDATIONS 6.3.1 Foundation Design Criteria The site soils are anticipated to have a expansion potential ranging from “very low” to “medium” when tested in accordance with ASTM D 4829. Additional testing of the soils should be performed during construction to evaluate the as-graded conditions. Additional recommendations may be necessary based on the as-graded soils conditions. A summary of GeoTek’s preliminary conventional foundation design recommendations is presented in the table below: Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 12 MINIMUM DESIGN REQUIREMENTS FOR CONVENTIONAL REINFORCED SHALLOW FOUNDATIONS Design Parameter “Very Low” Expansion Potential (0≤EI≤20) “Low” Expansion Potential (20≤EI≤50) “Medium” Expansion Potential (51≤EI≤90) Foundation Depth or Minimum Perimeter Beam Depth (inches below lowest adjacent grade) One-Story – 12 Two-Story – 12 Three-Story - 18 One-Story – 12 Two-Story – 12 Three-Story - 18 One-Story – 18 Two-Story – 18 Three-Story - 24 Minimum Foundation Width (Inches)* One-Story – 12 Two-Story – 12 Three-Story – 15 One-Story – 12 Two-Story – 12 Three-Story – 15 One-Story – 12 Two-Story – 12 Three-Story – 15 Minimum Slab Thickness (actual) 4 inches (actual) 4 inches (actual) 4 inches (actual) Minimum Slab Reinforcing 6” x 6” – W1.4/W1.4 welded wire fabric placed in middle of slab 6” x 6” – W2.9/W2.9 welded wire fabric or No. 3 reinforcing bars at 24 inches on center each way placed in middle of slab No. 3 reinforcing bars at 18 inches on center each way placed in middle of slab Minimum Footing Reinforcement Two No. 4 Reinforcing Bars, one top and one bottom Two No. 4 Reinforcing Bars, one top and one bottom Four No. 4 Reinforcing Bars, Two top and two bottom Effective Plasticity Index** NA 15 20 Presaturation of Subgrade Soil (Percent of Optimum/Depth in inches) Minimum 100% of the optimum moisture content to a depth of at least 12 inches prior to placing concrete Minimum 110% of the optimum moisture content to a depth of at least 12 inches prior to placing concrete Minimum 120% of the optimum moisture content to a depth of at least 18 inches prior to placing concrete *Code minimums per Table 1809.7 of the 2019 CBC should be complied with. **Effective Plasticity Index should be verified at the completion of the rough grading It should be noted that the criteria provided are based on soil support characteristics only. The structural engineer should design the slab and beam/footing reinforcement based on actual loading conditions. An allowable bearing capacity of 2,000 pounds per square foot (psf) may be used for design of continuous and perimeter footings at least 12 inches deep and 12 inches wide, and pad footings 24 inches square and 12 inches deep. This allowable soil bearing capacity may be increased by 400 psf for each additional foot of footing depth and 200 psf for each additional foot of footing width to a maximum value of 3,000 psf. An increase of one-third may be applied when considering short-term live loads (e.g., seismic and wind loads). Structural foundations should be designed in accordance with the 2019 CBC, and to withstand a total static settlement of one-inch and a differential static settlement of one-half of the total Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 13 settlement over a horizontal distance of 30 feet. A total seismically induced settlement of approximately 0.5 inches and a differential seismically induced settlement of about 0.25 inches over a horizontal distance of 30 feet are also anticipated. The passive earth pressure may be computed as an equivalent fluid having a density of 230 psf per foot of depth, to a maximum earth pressure of 2,000 psf for footings founded on engineered fill. A coefficient of friction between soil and concrete of 0.3 may be used with dead load forces. The passive pressure and frictional resistance can be combined without reduction. The upper one foot of soil should be ignored in the passive pressure calculations unless the surface is covered with concrete or asphalt. The passive pressure and frictional resistance may be combined without reduction. A grade beam, a minimum of 12 inches wide and 12 inches deep, should be utilized across large entrances. The base of the grade beam should be at the same elevation as the bottom of the adjoining footings. Alternatively, the buildings may rest on post-tensioned slabs. If this foundation option is selected, GeoTek should be contacted to provide geotechnical design parameters. A moisture and vapor retarding system should be placed below slabs-on-grade where moisture migration through the slab is undesirable. Guidelines for these systems are provided in the 2019 California Green Building Standards Code (CALGreen) Section 4.505.2, the 2019 CBC Section 1907.1, ACI 360R-10, and ACI 302.2R-06. It should be realized that the effectiveness of the vapor retarding membrane can be adversely impacted as the result of construction related punctures (e.g. stake penetrations, tears, punctures from walking on the aggregate layer, etc.). These occurrences should be limited as much as possible during construction. Thicker membranes are generally more resistant to accidental puncture than thinner ones. Products specifically designed for use as moisture/vapor retarders may also be more puncture resistant. It is GeoTek’s opinion that a minimum ten mil thick membrane with joints properly overlapped and sealed should be considered, unless otherwise specified by the slab design professional. Moisture and vapor retarding systems are intended to provide a certain level of resistance to vapor and moisture transmission through the concrete, but do not eliminate it. The acceptable level of moisture transmission through the slab is to a large extent based on the type of flooring used and atmospheric conditions. Ultimately, the vapor retarding system should be comprised of suitable elements to limit migration of water and reduce transmission of water vapor through the slab to acceptable levels. The selected elements should have suitable properties (i.e. thickness, composition, strength, and Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 14 permeance) to achieve the desired performance level. Consideration should be given to consulting with an individual possessing specific expertise in this area for additional evaluation. 6.3.2 Miscellaneous Foundation Recommendations  To minimize moisture penetration beneath the slab on grade areas, utility trenches should be backfilled with engineered fill, lean concrete, or concrete slurry where they intercept the perimeter footing or thickened slab edge.  Soils from the footing excavations should not be placed in the slab-on-grade areas unless properly compacted and tested. The excavations should be free of loose/sloughed materials and be neatly trimmed at the time of concrete placement.  Under-slab utility trenches should be compacted to project specifications. Compaction should be achieved with a mechanical compaction device. If backfill soils have dried out, they should be thoroughly moisture conditioned prior to placement in trenches. 6.3.3 Foundation Set Backs Foundations should comply with the following setbacks. Improvements not conforming to these setbacks are subject to the increased likelihood of excessive lateral movements and/or differential settlements. If large enough, these movements can compromise the integrity of the improvements. The following recommendations are presented:  The outside bottom edge of all footings should be set back a minimum of H/2 (where H is the slope height) from the face of any ascending slope. The setback should be at least five (5) feet and need not to exceed fifteen (15) feet. Where a retaining wall is constructed at the toe of the slope, the height of the slope should be measured from top of the wall to the top of the slope.  The outside bottom edge of all footings should be set back a minimum of H/3 from the face of any descending slope. The setback should be at least seven (7) feet and need not exceed forty (40) feet.  The bottom of all footings for structures near retaining walls should be deepened so as to extend below a 1:1 (h:v) projection upward from the bottom inside edge of the wall foundation.  The bottom of any planned foundations for structures should be deepened so as to extend below a 1:1 (h:v) projection upward from the bottom of the nearest excavation.

Katella Avenue, Orange, California Page 15 6.3.4 Retaining Wall Design and Construction 6.3.4.1 General Design Criteria Recommendations presented in this report apply to typical masonry or concrete walls retaining up to six feet of soils. Additional review and recommendations should be requested for higher walls. These are typical design criteria and are not intended to supersede the design by the structural engineer. Retaining wall foundations should be embedded a minimum of 12 inches into “very low” and “low” expansive soils and a minimum of 18 inches into “medium” expansive soils. Foundations should be designed in accordance with Section 6.3.1 of this report. Structural needs may govern and should be evaluated by the project structural engineer. All earth retention structure plans, as applicable, should be reviewed by this office prior to finalization. The seismic design parameters as discussed in this report remain applicable to all proposed earth retention structures at this site and should be properly incorporated into the design and construction of the structures. Earthwork considerations, site clearing and remedial earthwork for all earth retention structures should meet the requirements of this report, unless specifically provided otherwise, or more stringent requirements or recommendations are made by the designer. The backfill material placement for all earth retention structures should meet the requirement of Section 6.3.4.4 in this report. In general, cantilever earth retention structures, which are designed to yield at least 0.001H, where H is equal to the height of the earth retention structure to the base of its footing, may be designed using the active condition. Rigid earth retention structures (including but not limited to rigid walls, and walls braced at top, such as typical basement walls) should be designed using the at-rest condition. In addition to the design lateral forces due to retained earth, surcharges due to improvements, such as an adjacent building or traffic loading, should be considered in the design of the earth retention structures. Loads applied within a 1:1 (h:v) projection from the surcharge on the stem and footing of the earth retention structure should be considered in the design. Final selection of the appropriate design parameters should be made by the designer of the earth retention structures. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 16 6.3.4.2 Cantilevered Walls The recommendations presented below are for cantilevered walls retaining up to six feet of soils. Active earth pressure may be used for retaining wall design, provided the top of the wall is not restrained from minor deflections. An equivalent fluid pressure approach may be used to compute the horizontal pressure against the wall. Appropriate fluid unit weights are given below for specific slope gradients of the retained material. These do not include other superimposed loading conditions such as traffic, structures, or adverse geologic conditions. ACTIVE EARTH PRESSURES Surface Slope of Retained Materials (h:v) Equivalent Fluid Pressure (pcf) Selected Native Backfill* Equivalent Fluid Pressure (pcf) Import Granular Backfill** Level 45 36 2:1 81 53 *The design pressures assume the native backfill material has an expansion index less than or equal to 50 and a friction angle of about 28 degrees or better. Backfill zone includes area between the back of the wall and footing to a plane (1:1 h:v) up from the bottom of the wall foundation to the ground surface. **The design pressures assume that import granular backfill material has an expansion index less than or equal to 20 and a friction angle of at least 34 degrees. Backfill zone includes area between the back of the wall and footing to a plane (1:1 h:v) up from the bottom of the wall foundation to the ground surface. 6.3.4.3 Restrained Retaining Walls Retaining walls that will be restrained prior to placing and compacting backfill material, or that have reentrant or male corners, should be designed for an at-rest equivalent fluid pressure of 66 pcf, plus any applicable surcharge loading, for native backfill and level back slope condition. For imported granular backfill, an at-rest equivalent fluid pressure of 57 pcf should be utilized. For areas of male or reentrant corners, the restrained wall design should extend a minimum distance of twice the height of the wall laterally from the corner, or a distance otherwise determined by the project structural engineer. 6.3.4.4 Retaining Wall Backfill and Drainage Retaining wall backfill should be free of deleterious and/or oversized materials and should have properties indicated in Section 6.3.4.2. Retaining walls should be provided with an adequate pipe and gravel back drain system to help prevent buildup of hydrostatic pressures. Backdrains should consist of a four-inch diameter perforated collector pipe (Schedule 40, SDR 35, or approved equivalent) embedded in a minimum of one-cubic foot per linear foot of ¾- to 1-inch clean crushed rock or an approved equivalent, wrapped in filter fabric (Mirafi 140N or an approved Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 17 equivalent). The drain system should be connected to a suitable outlet. Waterproofing of site walls should be performed where moisture migration through the wall is undesirable. Retaining wall backfill should be placed in lifts no greater than eight inches in thickness and compacted to a minimum of 90 percent relative compaction in accordance with ASTM Test Method D 1557. The wall backfill should also include a minimum one-foot wide section of ¾- to 1-inch clean crushed rock (or an approved equivalent). The rock should be placed immediately adjacent to the back of the wall and extend up from a back drain to within approximately 24 inches of the finish grade. The rock should be separated from the earth with filter fabric. The upper 24 inches should consist of compacted on-site soil. As an alternative to the drain rock and fabric, Miradrain 2000, or approved equivalent, may be used behind the retaining wall. The Miradrain 2000 should extend from the base of the wall to within two feet of the ground surface. The subdrain should be placed at the base of the wall in direct contact with the Miradrain 2000. The presence of other materials might necessitate revision to the parameters provided and modification of the wall designs. Proper surface drainage needs to be provided and maintained. 6.3.4.5 Other Design Considerations  Wall design should consider the additional surcharge loads from superjacent slopes and/or footings, where appropriate.  No backfill should be placed against concrete until minimum design strengths are evident by compression tests of cylinders.  The retaining wall footing excavations, backcuts, and backfill materials should be approved the project geotechnical engineer or their authorized representative. 6.3.5 Pavement Design Considerations Pavement design for proposed on-site parking and drive areas was conducted per Caltrans Highway Design Manual guidelines for flexible pavements and the Portland Cement Association for rigid pavements. Based on an assumed design R-value of 20 and for Traffic Indexes (TIs) of 5.0 for car parking areas and 6.0 for drive areas for light traffic with occasional truck traffic, the following preliminary sections were calculated: Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 18 PRELIMINARY PAVEMENT SECTIONS Traffic Index Thickness of Flexible Pavement Section Thickness of Rigid Pavement Section 5.0 3” AC / 7.5” AB -- 6.0 4” AC / 8.5” AB 6.5” PCC/ 4” AB *AC = Asphalt Concrete, AB = Aggregate Base, PCC = Portland Cement Concrete with a f’c > 3,500 psi. The TIs used in our pavement design are considered reasonable values for the proposed pavement areas and should provide a pavement life of approximately 20 years with a normal amount of flexible pavement maintenance. Irrigation adjacent to pavements, without a deep curb or other cutoff to separate landscaping from the paving may result in premature pavement failure. Traffic parameters used for design were selected based upon engineering judgment and not upon information furnished to us such as an equivalent wheel load analysis or a traffic study. No structural reinforcement of the concrete pavements is required. However, temperature and shrinkage control reinforcement should be provided. This reinforcement should consist of No, 4 rebars on 24-inch centers, each way, or equivalent. The reinforcement should be placed at mid-height to the concrete pavement. Also, the concrete pavement should be provided with proper joints to help control cracking. All materials and methods of construction should also conform to the requirements of the City of Orange. These pavement sections should be considered preliminary until reviewed and approved by the City. The recommended pavement sections provided are intended as a minimum guideline and final selection of pavement cross section parameters should be made by the project civil engineer, based upon the local laws and ordinates, expected subgrade and pavement response, and desired level of conservatism. If thinner or highly variable pavement sections are constructed, increased maintenance and repair could be expected. Final pavement design should be checked by testing of soils exposed at subgrade (the upper one foot) after final grading has been completed. Asphalt concrete and aggregate base should conform to current Caltrans Standard Specifications Section 39 and 26-1.02, respectively. As an alternative, asphalt concrete can conform to Section 203-6 of the current Standard Specifications for Public Work (Green Book). Crushed aggregate base or crushed miscellaneous base can conform to Section 200-2.2 and 200-2.4 of the Green Book, respectively. Pavement base should be compacted to at least 95 percent of the ASTM D1557 laboratory maximum dry density (modified proctor). All pavement installation, including preparation and compaction of subgrade, compaction of base material, placement and rolling of asphaltic concrete, should be done in accordance with the City of Orange specifications, and under the observation and testing of GeoTek and a City Inspector Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 19 where required. Jurisdictional minimum compaction requirements in excess of the aforementioned minimums may govern. Deleterious material, excessive wet or dry pockets, oversized rock fragments, and other unsuitable yielding materials encountered during grading should be removed. Once existing compacted fill are brought to the proposed pavement subgrade elevations, the subgrade should be proof-rolled in order to check for a uniform and unyielding surface. The upper 12 inches of pavement subgrade soils should be scarified, moisture conditioned at or near optimum moisture content, and recompacted to at least 95 percent of the laboratory maximum dry density (ASTM D1557). If loose or yielding materials are encountered during construction, additional evaluation of these areas should be carried out by GeoTek. All pavement section changes should be properly transitioned. 6.3.6 Soil Corrosivity The soil resistivity was tested in the laboratory on two samples collected during our field exploration. The results of the testing (2,750 and 2,814 ohm-cm) indicate that the soil samples are “highly corrosive” to buried ferrous metals, based on the guidelines provided in Corrosion Basics: An Introduction (Roberge, 2005). Consideration should be given to consulting with a corrosion engineer. 6.3.7 Soil Sulfate Content The sulfate content was determined in the laboratory for two soil samples obtained during our field exploration. The results (0.0027 and 0.0103 percent) indicate that the water-soluble sulfate range is less than 0.1 percent by weight which is considered “not applicable” (i.e. negligible) as per Table 4.2.1 of ACI 318. Based upon the test results, no special concrete mix design is required by Code for sulfate attack resistance. Additional testing of soils collected near finish grade should be performed subsequent to site grading. 6.3.8 Import Soils Import soils should have a “very low” expansion potential. GeoTek also recommends that, as a minimum, proposed import soils be tested for soluble sulfate content. GeoTek should be notified a minimum of 72 hours of potential import sources so that appropriate sampling and laboratory testing can be performed. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 20 6.3.9 Concrete Flatwork 6.3.9.1 Exterior Concrete Slabs, Sidewalks, and Driveways Exterior concrete slabs, sidewalks, and driveways should be designed using a four-inch minimum thickness. No specific reinforcement is required due to the non-structural nature. However, the use of some reinforcement should be considered. Some shrinkage and cracking of the concrete should be anticipated as a result of typical mix designs and curing practices commonly utilized in residential construction. Sidewalks and driveways may be under the jurisdiction of the governing agency. If so, jurisdictional design and construction criteria would apply, if more restrictive than the recommendations presented herein. Subgrade soils should be pre-moistened prior to placing concrete. The subgrade with “very low” expansion potential should be pre-saturated to a minimum of 100 percent of optimum moisture content to a depth of at least 12 inches. Soils with “low” and “medium” expansion potentials should be pre-saturated to a minimum of 110 and 120 percent of optimum moisture content, respectively. Presaturation depth should be at least 12 inches. All concrete installation, including preparation and compaction of subgrade, should be done in accordance with the City of Orange specifications, and under the observation and testing of GeoTek and a City Inspector, if necessary. 6.3.9.2 Concrete Performance Concrete cracks should be expected. These cracks can vary from sizes that are essentially unnoticeable to more than 1/8 inch in width. Most cracks in concrete, while unsightly, do not significantly impact long-term performance. While it is possible to take measures (proper concrete mix, placement, curing, control joints, etc.) to reduce the extent and size of cracks that occur, some cracking will occur despite the best efforts to minimize it. Concrete can also undergo chemical processes that are dependent on a wide range of variables, which are difficult, at best, to control. Concrete, while seemingly a stable material, is also subject to internal expansion and contraction due to external changes over time. One of the simplest means to control cracking is to provide weakened control joints for cracking to occur along. These do not prevent cracks from developing; they simply provide a relief point for the stresses that develop. These joints are a widely accepted means to control cracks but are not always effective. Control joints are more effective the more closely spaced they are. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 21 GeoTek suggests that control joints be placed in two directions and located a distance apart roughly equal to 24 to 36 times the slab thickness. Exterior concrete flatwork (patios, walkways, driveways, etc.) is often some of the most visible aspects of site development. They are typically given the least level of quality control, being considered “non-structural” components. We suggest that the same standards of care be applied to these features as to the structure itself. 6.4 POST CONSTRUCTION CONSIDERATIONS 6.4.1 Landscape Maintenance and Planting Water has been shown to weaken the inherent strength of soil, and slope stability is significantly reduced by overly wet conditions. Positive surface drainage away from graded slopes should be maintained and only the amount of irrigation necessary to sustain plant life should be provided for planted slopes. Controlling surface drainage and runoff and maintaining a suitable vegetation cover can minimize erosion. Plants selected for landscaping should be lightweight, deep-rooted types that require little water and are capable of surviving the prevailing climate. Overwatering should be avoided. The soils should be maintained in a solid to semi-solid state as defined by the materials Atterberg Limits. Care should be taken when adding soil amendments to avoid excessive watering. Leaching as a method of soil preparation prior to planting is not recommended. An abatement program to control ground-burrowing rodents should be implemented and maintained. This is critical as burrowing rodents can decreased the long-term performance of slopes. It is common for planting to be placed adjacent to structures in planter or lawn areas. This will result in the introduction of water into the ground adjacent to the foundation. This type of landscaping should be avoided. If used, then extreme care should be exercised with regard to the irrigation and drainage in these areas. 6.4.2 Drainage The need to maintain proper surface drainage and subsurface systems cannot be overly emphasized. Positive site drainage should be maintained at all times. Drainage should not flow uncontrolled down any descending slope. Water should be directed away from foundations and not allowed to pond or seep into the ground. Pad drainage should be directed toward approved area(s) and not be blocked by other improvements. Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 22 It is the owner’s responsibility to maintain and clean drainage devices on or contiguous to their lot. In order to be effective, maintenance should be conducted on a regular and routine schedule and necessary corrections made prior to each rainy season. 6.5 PLAN REVIEW AND CONSTRUCTION OBSERVATIONS We recommend that site grading plans, pool plans, retaining wall plans, foundation plans, and relevant project specifications be reviewed by this office prior to construction to check for conformance with the recommendations of this report. We also recommend that GeoTek representatives be present during site grading and foundation construction to check for proper implementation of the geotechnical recommendations. The owner/developer should verify that GeoTek representatives perform at least the following duties:  Observe site clearing and grubbing operations for proper removal of unsuitable materials.  Observe and test bottom of removals prior to fill placement.  Evaluate the suitability of onsite and import materials for fill placement and collect soil samples for laboratory testing where necessary.  Observe the fill for uniformity during placement, including utility trenches.  Perform field density testing of the fill materials.  Observe and probe foundation excavations to confirm suitability of bearing materials. If requested, a construction observation and compaction report can be provided by GeoTek, which can comply with the requirements of the governmental agencies having jurisdiction over the project. We recommend that these agencies be notified prior to commencement of construction so that necessary grading permits can be obtained. 7. INTENT It is the intent of this report to aid in the design and construction of the proposed development. Implementation of the advice presented in this report is intended to reduce risk associated with construction projects. The professional opinions and geotechnical advice contained in this report are not intended to imply total performance of the project or guarantee that unusual or variable conditions will not be discovered during or after construction. The scope of our evaluation is limited to the boundaries of the subject site. This review does not and should in no way be construed to encompass any areas beyond the specific area of the proposed construction as indicated to us by the client. Further, no evaluation of any existing site improvements is included. The scope is based on our understanding of the project and the Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page 23 client’s needs, our fee estimate (P-04010622-CR) dated April 20, 2022 and geotechnical engineering standards normally used on similar projects in this region. 8. LIMITATIONS The materials observed on the project site appear to be representative of the area; however, soil materials vary in character between excavations or conditions exposed during site construction. Site conditions may vary due to seasonal changes or other factors. GeoTek, Inc. assumes no responsibility or liability for work, testing or recommendations performed or provided by others. Since our recommendations are based on the site conditions observed and encountered, and laboratory testing, our conclusion and recommendations are professional opinions that are limited to the extent of the available data. Observations during construction are important to allow for any change in recommendations found to be warranted. These opinions have been derived in accordance with current standards of practice and no warranty is expressed or implied. Standards of practice are subject to change with time. 9.

Katella Avenue, Orange, California Page B-1 A - FIELD TESTING AND SAMPLING PROCEDURES The Modified Split-Barrel Sampler (Ring) The ring sampler is driven into the ground in accordance with ASTM Test Method D 3550. The sampler, with an external diameter of 3.0 inches, is lined with 1-inch long, thin brass rings with inside diameters of approximately 2.4 inches. The sampler is typically driven into the ground 12 or 18 inches with a 140- pound hammer free falling from a height of 30 inches. Blow counts are recorded for every 6 inches of penetration as indicated on the logs of borings. The samples are removed from the sample barrel in the brass rings, sealed, and transported to the laboratory for testing. Bulk Samples (Large) These samples are normally large bags of earth materials over 20 pounds in weight collected from the field by means of hand digging or exploratory cuttings. Bulk Samples (Small) These are plastic bag samples which are normally airtight and contain less than five pounds in weight of earth materials collected from the field by means of hand digging or exploratory cuttings. These samples are primarily used for determining natural moisture content and classification indices.

Katella Avenue, Orange, California Project No. 3193-CR Intracorp SW, LLC Project No. 3193-CR Updated Geotechnical and Infiltration Evaluation June 3, 2022 901 E. Katella Avenue, Orange, California Page C-1 SUMMARY OF LABORATORY TESTING Classification Soils were classified visually in general accordance with the Unified Soil Classification System (ASTM Test Method D 2487). The soil classifications are shown on the logs of exploratory borings in Appendix B. Collapse Collapse tests were conducted in accordance with ASTM D4546. The results of these tests are presented herewith. Expansion Index The expansion potential of the soils was determined by performing expansion index tests on two representative soil samples from the site in general accordance with ASTM D 4829. The results of these tests are presented herewith. In Situ Moisture Content and Unit Weight The field moisture content was measured in the laboratory on selected samples collected during the field investigation. The field moisture content is determined as a percentage of the dry unit weight. The dry density was measured in the laboratory on selected ring samples. The results are shown on the logs of exploratory borings in Appendix B. Moisture-Density Relationship Laboratory testing was performed on two representative soil samples collected during the subsurface exploration. The laboratory maximum dry density and optimum moisture content for the soil type was determined in general accordance with test method ASTM Test Procedure D 1557. The results are presented herewith.

Katella Avenue, Orange, California Project No. 3193-CR GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 1 901 E. Katella Avenue, Orange, California Project No. 3193-CR GENERAL GRADING GUIDELINES Guidelines presented herein are intended to address general construction procedures for earthwork construction. Specific situations and conditions often arise which cannot reasonably be discussed in general guidelines, when anticipated these are discussed in the text of the report. Often unanticipated conditions are encountered which may necessitate modification or changes to these guidelines. It is our hope that these will assist the contractor to more efficiently complete the project by providing a reasonable understanding of the procedures that would be expected during earthwork and the testing and observation used to evaluate those procedures. General Grading should be performed to at least the minimum requirements of governing agencies, Chapters 18 and 33 of the California Building Code, CBC (2019) and the guidelines presented below. Preconstruction Meeting A preconstruction meeting should be held prior to site earthwork. Any questions the contractor has regarding our recommendations, general site conditions, apparent discrepancies between reported and actual conditions and/or differences in procedures the contractor intends to use should be brought up at that meeting. The contractor (including the main onsite representative) should review our report and these guidelines in advance of the meeting. Any comments the contractor may have regarding these guidelines should be brought up at that meeting. Grading Observation and Testing 1. Observation of the fill placement should be provided by our representative during grading. Verbal communication during the course of each day will be used to inform the contractor of test results. The contractor should receive a copy of the "Daily Field Report" indicating results of field density tests that day. If our representative does not provide the contractor with these reports, our office should be notified. 2. Testing and observation procedures are, by their nature, specific to the work or area observed and location of the tests taken, variability may occur in other locations. The contractor is responsible for the uniformity of the grading operations; our observations and test results are intended to evaluate the contractor’s overall level of efforts during grading. The contractor’s personnel are the only individuals participating in all aspect of site work. Compaction testing and observation should not be considered as relieving the contractor’s responsibility to properly compact the fill. 3. Cleanouts, processed ground to receive fill, key excavations, and subdrains should be observed by our representative prior to placing any fill. It will be the contractor's responsibility to notify our representative or office when such areas are ready for observation. 4. Density tests may be made on the surface material to receive fill, as considered warranted by this firm. 5. In general, density tests would be made at maximum intervals of two feet of fill height or every 1,000 cubic yards of fill placed. Criteria will vary depending on soil conditions and size of the fill. More frequent testing may be performed. In any case, an adequate number of field density tests should be made to evaluate the required compaction and moisture content is generally being obtained. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 2 901 E. Katella Avenue, Orange, California Project No. 3193-CR 6. Laboratory testing to support field test procedures will be performed, as considered warranted, based on conditions encountered (e.g. change of material sources, types, etc.) Every effort will be made to process samples in the laboratory as quickly as possible and in progress construction projects are our first priority. However, laboratory workloads may cause in delays and some soils may require a minimum of 48 to 72 hours to complete test procedures. Whenever possible, our representative(s) should be informed in advance of operational changes that might result in different source areas for materials. 7. Procedures for testing of fill slopes are as follows: a) Density tests should be taken periodically during grading on the flat surface of the fill, three to five feet horizontally from the face of the slope. b) If a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. 8. Finish grade testing of slopes and pad surfaces should be performed after construction is complete. Site Clearing 1. All vegetation, and other deleterious materials, should be removed from the site. If material is not immediately removed from the site it should be stockpiled in a designated area(s) well outside of all current work areas and delineated with flagging or other means. Site clearing should be performed in advance of any grading in a specific area. 2. Efforts should be made by the contractor to remove all organic or other deleterious material from the fill, as even the most diligent efforts may result in the incorporation of some materials. This is especially important when grading is occurring near the natural grade. All equipment operators should be aware of these efforts. Laborers may be required as root pickers. 3. Nonorganic debris or concrete may be placed in deeper fill areas provided the procedures used are observed and found acceptable by our representative. Treatment of Existing Ground 1. Following site clearing, all surficial deposits of alluvium and colluvium as well as weathered or creep effected bedrock, should be removed unless otherwise specifically indicated in the text of this report. 2. In some cases, removal may be recommended to a specified depth (e.g. flat sites where partial alluvial removals may be sufficient). The contractor should not exceed these depths unless directed otherwise by our representative. 3. Groundwater existing in alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 4. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. 5. Exploratory back hoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Fill Placement 1. Unless otherwise indicated, all site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see text of report). GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 3 901 E. Katella Avenue, Orange, California Project No. 3193-CR 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts six (6) to eight (8) inches in compacted thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a nearly horizontal plane, unless otherwise found acceptable by our representative. 3. If the moisture content or relative density varies from that recommended by this firm, the contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be at or above optimum moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. The ability of the contractor to obtain the proper moisture content will control production rates. b) Each six-inch layer should be compacted to at least 90 percent of the maximum dry density in compliance with the testing method specified by the controlling governmental agency. In most cases, the testing method is ASTM Test Designation D 1557. 4. Rock fragments less than eight inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is observed by, and acceptable to, our representative. 5. Rocks exceeding eight (8) inches in diameter should be taken off site, broken into smaller fragments, or placed in accordance with recommendations of this firm in areas designated suitable for rock disposal. On projects where significant large quantities of oversized materials are anticipated, alternate guidelines for placement may be included. If significant oversize materials are encountered during construction, these guidelines should be requested. 6. In clay soil, dry or large chunks or blocks are common. If in excess of eight (8) inches minimum dimension, then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break up blocks. When dry, they should be moisture conditioned to provide a uniform condition with the surrounding fill. Slope Construction 1. The contractor should obtain a minimum relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. 2. Slopes trimmed to the compacted core should be overbuilt by at least three (3) feet with compaction efforts out to the edge of the false slope. Failure to properly compact the outer edge results in trimming not exposing the compacted core and additional compaction after trimming may be necessary. 3. If fill slopes are built "at grade" using direct compaction methods, then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled or otherwise compacted at approximately every 4 feet vertically as the slope is built. 4. Corners and bends in slopes should have special attention during construction as these are the most difficult areas to obtain proper compaction. 5. Cut slopes should be cut to the finished surface. Excessive undercutting and smoothing of the face with fill may necessitate stabilization. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 4 901 E. Katella Avenue, Orange, California Project No. 3193-CR UTILITY TRENCH CONSTRUCTION AND BACKFILL Utility trench excavation and backfill is the contractors responsibility. The geotechnical consultant typically provides periodic observation and testing of these operations. While efforts are made to make sufficient observations and tests to verify that the contractors’ methods and procedures are adequate to achieve proper compaction, it is typically impractical to observe all backfill procedures. As such, it is critical that the contractor use consistent backfill procedures. Compaction methods vary for trench compaction and experience indicates many methods can be successful. However, procedures that “worked” on previous projects may or may not prove effective on a given site. The contractor(s) should outline the procedures proposed, so that we may discuss them prior to construction. We will offer comments based on our knowledge of site conditions and experience. 1. Utility trench backfill in slopes, structural areas, in streets and beneath flat work or hardscape should be brought to at least optimum moisture and compacted to at least 90 percent of the laboratory standard. Soil should be moisture conditioned prior to placing in the trench. 2. Flooding and jetting are not typically recommended or acceptable for native soils. Flooding or jetting may be used with select sand having a Sand Equivalent (SE) of 30 or higher. This is typically limited to the following uses: a) shallow (12 + inches) under slab interior trenches and, b) as bedding in pipe zone. The water should be allowed to dissipate prior to pouring slabs or completing trench compaction. 3. Care should be taken not to place soils at high moisture content within the upper three feet of the trench backfill in street areas, as overly wet soils may impact subgrade preparation. Moisture may be reduced to 2% below optimum moisture in areas to be paved within the upper three feet below sub grade. 4. Sand backfill should not be allowed in exterior trenches adjacent to and within an area extending below a 1:1 projection from the outside bottom edge of a footing, unless it is similar to the surrounding soil. 5. Trench compaction testing is generally at the discretion of the geotechnical consultant. Testing frequency will be based on trench depth and the contractors procedures. A probing rod would be used to assess the consistency of compaction between tested areas and untested areas. If zones are found that are considered less compact than other areas, this would be brought to the contractors attention. JOB SAFETY General Personnel safety is a primary concern on all job sites. The following summaries are safety considerations for use by all our employees on multi-employer construction sites. On ground personnel are at highest risk of injury and possible fatality on grading construction projects. The company recognizes that construction activities will vary on each site and that job site safety is the contractor's responsibility. However, it is, imperative that all personnel be safety conscious to avoid accidents and potential injury. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 5 901 E. Katella Avenue, Orange, California Project No. 3193-CR In an effort to minimize risks associated with geotechnical testing and observation, the following precautions are to be implemented for the safety of our field personnel on grading and construction projects. 1. Safety Meetings: Our field personnel are directed to attend the contractor's regularly scheduled safety meetings. 2. Safety Vests: Safety vests are provided for and are to be worn by our personnel while on the job site. 3. Safety Flags: Safety flags are provided to our field technicians; one is to be affixed to the vehicle when on site, the other is to be placed atop the spoil pile on all test pits. In the event that the contractor's representative observes any of our personnel not following the above, we request that it be brought to the attention of our office. Test Pits Location, Orientation and Clearance The technician is responsible for selecting test pit locations. The primary concern is the technician's safety. However, it is necessary to take sufficient tests at various locations to obtain a representative sampling of the fill. As such, efforts will be made to coordinate locations with the grading contractors authorized representatives (e.g. dump man, operator, supervisor, grade checker, etc.), and to select locations following or behind the established traffic pattern, preferably outside of current traffic. The contractors authorized representative should direct excavation of the pit and safety during the test period. Again, safety is the paramount concern. Test pits should be excavated so that the spoil pile is placed away from oncoming traffic. The technician's vehicle is to be placed next to the test pit, opposite the spoil pile. This necessitates that the fill be maintained in a drivable condition. Alternatively, the contractor may opt to park a piece of equipment in front of test pits, particularly in small fill areas or those with limited access. A zone of non-encroachment should be established for all test pits (see diagram below). No grading equipment should enter this zone during the test procedure. The zone should extend outward to the sides approximately 50 feet from the center of the test pit and 100 feet in the direction of traffic flow. This zone is established both for safety and to avoid excessive ground vibration, which typically decreases test results. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 6 901 E.

The contractor's representative should effectively keep all equipment at a safe operation distance (e.g. 50 feet) away from the slope during testing. The technician is directed to withdraw from the active portion of the fill as soon as possible following testing. The technician's vehicle should be parked at the perimeter of the fill in a highly visible location. Trench Safety It is the contractor's responsibility to provide safe access into trenches where compaction testing is needed. Trenches for all utilities should be excavated in accordance with CAL-OSHA and any other applicable safety standards. Safe conditions will be required to enable compaction testing of the trench backfill. All utility trench excavations in excess of 5 feet deep, which a person enters, are to be shored or laid back. Trench access should be provided in accordance with OSHA standards. Our personnel are directed not to enter any trench by being lowered or "riding down" on the equipment. Our personnel are directed not to enter any excavation which; 1. is 5 feet or deeper unless shored or laid back, 2. exit points or ladders are not provided, 3. displays any evidence of instability, has any loose rock or other debris which could fall into the trench, or 4. displays any other evidence of any unsafe conditions regardless of depth. If the contractor fails to provide safe access to trenches for compaction testing, our company policy requires that the soil technician withdraws and notifies their supervisor. The contractors representative will then be contacted in an effort to effect a solution. All backfill not tested due to safety concerns or other reasons is subject to reprocessing and/or removal. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 7 901 E. Katella Avenue, Orange, California Project No. 3193-CR Procedures In the event that the technician's safety is jeopardized or compromised as a result of the contractor's failure to comply with any of the above, the technician is directed to inform both the developer's and contractor's representatives. If the condition is not rectified, the technician is required, by company policy, to immediately withdraw and notify their supervisor. The contractor’s representative will then be contacted in an effort to effect a solution. No further testing will be performed until the situation is rectified. Any fill placed in the interim can be considered unacceptable and subject to reprocessing, recompaction or removal. In the event that the soil technician does not comply with the above or other established safety guidelines, we request that the contractor bring this to technicians attention and notify our project manager or office. Effective communication and coordination between the contractors' representative and the field technician(s) is strongly encouraged in order to implement the above safety program and safety in general. The safety procedures outlined above should be discussed at the contractor's safety meetings. This will serve to inform and remind equipment operators of these safety procedures particularly the zone of non-encroachment. The safety procedures outlined above should be discussed at the contractor's safety meetings. This will serve to inform and remind equipment operators of these safety procedures particularly the zone of non-encroachment. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 1 901 E.

Procedures for testing of fill slopes are as follows: a) Density tests should be taken periodically during grading on the flat surface of the fill, three to five feet horizontally from the face of the slope. b) If a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. 8. Finish grade testing of slopes and pad surfaces should be performed after construction is complete. Site Clearing 1. All vegetation, and other deleterious materials, should be removed from the site. If material is not immediately removed from the site it should be stockpiled in a designated area(s) well outside of all current work areas and delineated with flagging or other means. Site clearing should be performed in advance of any grading in a specific area. 2. Efforts should be made by the contractor to remove all organic or other deleterious material from the fill, as even the most diligent efforts may result in the incorporation of some materials. This is especially important when grading is occurring near the natural grade. All equipment operators should be aware of these efforts. Laborers may be required as root pickers. 3. Nonorganic debris or concrete may be placed in deeper fill areas provided the procedures used are observed and found acceptable by our representative. Treatment of Existing Ground 1. Following site clearing, all surficial deposits of alluvium and colluvium as well as weathered or creep effected bedrock, should be removed unless otherwise specifically indicated in the text of this report. 2. In some cases, removal may be recommended to a specified depth (e.g. flat sites where partial alluvial removals may be sufficient). The contractor should not exceed these depths unless directed otherwise by our representative. 3. Groundwater existing in alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 4. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. 5. Exploratory back hoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Fill Placement 1. Unless otherwise indicated, all site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see text of report). GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 3 901 E. Katella Avenue, Orange, California Project No. 3193-CR 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts six (6) to eight (8) inches in compacted thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a nearly horizontal plane, unless otherwise found acceptable by our representative. 3. If the moisture content or relative density varies from that recommended by this firm, the contractor should rework the fill until it is in accordance with the following: a) Moisture content of the fill should be at or above optimum moisture. Moisture should be evenly distributed without wet and dry pockets. Pre-watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. The ability of the contractor to obtain the proper moisture content will control production rates. b) Each six-inch layer should be compacted to at least 90 percent of the maximum dry density in compliance with the testing method specified by the controlling governmental agency. In most cases, the testing method is ASTM Test Designation D 1557. 4. Rock fragments less than eight inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is observed by, and acceptable to, our representative. 5. Rocks exceeding eight (8) inches in diameter should be taken off site, broken into smaller fragments, or placed in accordance with recommendations of this firm in areas designated suitable for rock disposal. On projects where significant large quantities of oversized materials are anticipated, alternate guidelines for placement may be included. If significant oversize materials are encountered during construction, these guidelines should be requested. 6. In clay soil, dry or large chunks or blocks are common. If in excess of eight (8) inches minimum dimension, then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break up blocks. When dry, they should be moisture conditioned to provide a uniform condition with the surrounding fill. Slope Construction 1. The contractor should obtain a minimum relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. 2. Slopes trimmed to the compacted core should be overbuilt by at least three (3) feet with compaction efforts out to the edge of the false slope. Failure to properly compact the outer edge results in trimming not exposing the compacted core and additional compaction after trimming may be necessary. 3. If fill slopes are built "at grade" using direct compaction methods, then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled or otherwise compacted at approximately every 4 feet vertically as the slope is built. 4. Corners and bends in slopes should have special attention during construction as these are the most difficult areas to obtain proper compaction. 5. Cut slopes should be cut to the finished surface. Excessive undercutting and smoothing of the face with fill may necessitate stabilization. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 4 901 E. Katella Avenue, Orange, California Project No. 3193-CR UTILITY TRENCH CONSTRUCTION AND BACKFILL Utility trench excavation and backfill is the contractors responsibility. The geotechnical consultant typically provides periodic observation and testing of these operations. While efforts are made to make sufficient observations and tests to verify that the contractors’ methods and procedures are adequate to achieve proper compaction, it is typically impractical to observe all backfill procedures. As such, it is critical that the contractor use consistent backfill procedures. Compaction methods vary for trench compaction and experience indicates many methods can be successful. However, procedures that “worked” on previous projects may or may not prove effective on a given site. The contractor(s) should outline the procedures proposed, so that we may discuss them prior to construction. We will offer comments based on our knowledge of site conditions and experience. 1. Utility trench backfill in slopes, structural areas, in streets and beneath flat work or hardscape should be brought to at least optimum moisture and compacted to at least 90 percent of the laboratory standard. Soil should be moisture conditioned prior to placing in the trench. 2. Flooding and jetting are not typically recommended or acceptable for native soils. Flooding or jetting may be used with select sand having a Sand Equivalent (SE) of 30 or higher. This is typically limited to the following uses: a) shallow (12 + inches) under slab interior trenches and, b) as bedding in pipe zone. The water should be allowed to dissipate prior to pouring slabs or completing trench compaction. 3. Care should be taken not to place soils at high moisture content within the upper three feet of the trench backfill in street areas, as overly wet soils may impact subgrade preparation. Moisture may be reduced to 2% below optimum moisture in areas to be paved within the upper three feet below sub grade. 4. Sand backfill should not be allowed in exterior trenches adjacent to and within an area extending below a 1:1 projection from the outside bottom edge of a footing, unless it is similar to the surrounding soil. 5. Trench compaction testing is generally at the discretion of the geotechnical consultant. Testing frequency will be based on trench depth and the contractors procedures. A probing rod would be used to assess the consistency of compaction between tested areas and untested areas. If zones are found that are considered less compact than other areas, this would be brought to the contractors attention. JOB SAFETY General Personnel safety is a primary concern on all job sites. The following summaries are safety considerations for use by all our employees on multi-employer construction sites. On ground personnel are at highest risk of injury and possible fatality on grading construction projects. The company recognizes that construction activities will vary on each site and that job site safety is the contractor's responsibility. However, it is, imperative that all personnel be safety conscious to avoid accidents and potential injury. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 5 901 E. Katella Avenue, Orange, California Project No. 3193-CR In an effort to minimize risks associated with geotechnical testing and observation, the following precautions are to be implemented for the safety of our field personnel on grading and construction projects. 1. Safety Meetings: Our field personnel are directed to attend the contractor's regularly scheduled safety meetings. 2. Safety Vests: Safety vests are provided for and are to be worn by our personnel while on the job site. 3. Safety Flags: Safety flags are provided to our field technicians; one is to be affixed to the vehicle when on site, the other is to be placed atop the spoil pile on all test pits. In the event that the contractor's representative observes any of our personnel not following the above, we request that it be brought to the attention of our office. Test Pits Location, Orientation and Clearance The technician is responsible for selecting test pit locations. The primary concern is the technician's safety. However, it is necessary to take sufficient tests at various locations to obtain a representative sampling of the fill. As such, efforts will be made to coordinate locations with the grading contractors authorized representatives (e.g. dump man, operator, supervisor, grade checker, etc.), and to select locations following or behind the established traffic pattern, preferably outside of current traffic. The contractors authorized representative should direct excavation of the pit and safety during the test period. Again, safety is the paramount concern. Test pits should be excavated so that the spoil pile is placed away from oncoming traffic. The technician's vehicle is to be placed next to the test pit, opposite the spoil pile. This necessitates that the fill be maintained in a drivable condition. Alternatively, the contractor may opt to park a piece of equipment in front of test pits, particularly in small fill areas or those with limited access. A zone of non-encroachment should be established for all test pits (see diagram below). No grading equipment should enter this zone during the test procedure. The zone should extend outward to the sides approximately 50 feet from the center of the test pit and 100 feet in the direction of traffic flow. This zone is established both for safety and to avoid excessive ground vibration, which typically decreases test results. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 6 901 E.

The contractor's representative should effectively keep all equipment at a safe operation distance (e.g. 50 feet) away from the slope during testing. The technician is directed to withdraw from the active portion of the fill as soon as possible following testing. The technician's vehicle should be parked at the perimeter of the fill in a highly visible location. Trench Safety It is the contractor's responsibility to provide safe access into trenches where compaction testing is needed. Trenches for all utilities should be excavated in accordance with CAL-OSHA and any other applicable safety standards. Safe conditions will be required to enable compaction testing of the trench backfill. All utility trench excavations in excess of 5 feet deep, which a person enters, are to be shored or laid back. Trench access should be provided in accordance with OSHA standards. Our personnel are directed not to enter any trench by being lowered or "riding down" on the equipment. Our personnel are directed not to enter any excavation which; 1. is 5 feet or deeper unless shored or laid back, 2. exit points or ladders are not provided, 3. displays any evidence of instability, has any loose rock or other debris which could fall into the trench, or 4. displays any other evidence of any unsafe conditions regardless of depth. If the contractor fails to provide safe access to trenches for compaction testing, our company policy requires that the soil technician withdraws and notifies their supervisor. The contractors representative will then be contacted in an effort to effect a solution. All backfill not tested due to safety concerns or other reasons is subject to reprocessing and/or removal. GENERAL GRADING GUIDELINES APPENDIX E Intracorp SW, LLC Page 7 901 E. Katella Avenue, Orange, California Project No. 3193-CR Procedures In the event that the technician's safety is jeopardized or compromised as a result of the contractor's failure to comply with any of the above, the technician is directed to inform both the developer's and contractor's representatives. If the condition is not rectified, the technician is required, by company policy, to immediately withdraw and notify their supervisor. The contractor’s representative will then be contacted in an effort to effect a solution. No further testing will be performed until the situation is rectified. Any fill placed in the interim can be considered unacceptable and subject to reprocessing, recompaction or removal. In the event that the soil technician does not comply with the above or other established safety guidelines, we request that the contractor bring this to technicians attention and notify our project manager or office. Effective communication and coordination between the contractors' representative and the field technician(s) is strongly encouraged in order to implement the above safety program and safety in general. The safety procedures outlined above should be discussed at the contractor's safety meetings. This will serve to inform and remind equipment operators of these safety procedures particularly the zone of non-encroachment. The safety procedures outlined above should be discussed at the contractor's safety meetings. This will serve to inform and remind equipment operators of these safety procedures particularly the zone of non-encroachment. group, inc. engineering NOISE IMPACT STUDY 901 E.

Katella Avenue In-Fill Residential Development (hereinafter referred to as “Project”) and provide recommendations, if necessary, to minimize any project noise impacts. The assessment was conducted within the context of the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000, et seq.) and the standards and methodology follow the City of Orange noise requirements. The following is provided in this report: • A description of the study area and the proposed project • Information regarding the fundamentals of noise • Identification of the regulatory setting and applicable noise standards • Analysis of the existing noise environment • Analysis of the project’s operational noise impact on adjacent sensitive receptors • Analysis of the project’s construction noise and vibration impact on adjacent sensitive receptors • Analysis of the project’s noise/land use compatibility • Summary of recommended mitigation measures and project design features to reduce noise level impacts. 1.2 Site Location The proposed project is located at 901 E. Katella Ave., on the northeast corner of the intersection of Cambridge Street and Katella Avenue, in the City of Orange, California. The project site is currently developed with a vacant AT&T call center. The project site is bounded by residential uses to the north, Katella Avenue to the south, commercial uses to the east, and Cambridge Street to the west. The project site is located within a General Commercial (GC) land use designation and is bordered along the northern property line by a Low Density Residential (LDR) land use designation. The nearest noise-sensitive land uses surrounding the project site include: • Existing adjacent residential land uses located directly north of the project site 1-2 • Existing adjacent residential land use to the northwest of the project site, approximately 125 feet from the centerline of Cambridge Street The project site location map is provided in Exhibit A. 1.3 Project Description The proposed project consists of razing the existing vacant AT&T call center and constructing forty-nine (49) residential units with a density of 18.1 DU/AC. The site plan used for this analysis, provided by BASSENIAN LAGONI ARCHITECTS, is illustrated in Exhibit B. Table 1 summarizes the proposed project land uses. Table 1 Land Use Summary Project Land Use Amount Metric Multifamily Residential 49 Dwelling Units Parking Lot 128 Spaces This report analyzes the short-term noise impacts associated with construction activities and long-term noise impacts associated with the day-to-day operation of the project. The primary source of operational noise includes residential HVAC mechanical equipment noise and on-site vehicle circulation noise. The project is proposing to build a noise barrier wall (minimum six (6) feet high) along the eastern property line. An existing six (6) foot tall noise barrier wall is located along the northern property line. It should be noted that this study was conducted in November 2022 based on the proposed project including 52 residential dwelling units and 117 parking spaces. The project site plan has since been revised to include 49 dwelling units and 128 parking spaces. No significant changes or new sources of noise have been added to the proposed project. Therefore, this report conservatively analyzes noise impacts based on the original site plan. 1-3 1.4 Summary of Analysis Results Table 2 provides a summary of the noise analysis results, per the CEQA impact criteria checklist. The project is not expected to result in the generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. Table 2 CEQA Noise Impact Criteria Noise Impact Criteria Potentially Significant Potentially Significant Unless Mitigated Less Than Significant Impact No Impact Would the project result in? a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? X b) Generation of excessive ground-borne vibration or ground-borne noise levels? X c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? X 1.5 Recommended Project Design Features (DF) The following recommended project design features include standard rules and requirements, best practices, and recognized design guidelines for reducing noise levels. Design features are assumed to be part of the conditions of the project and integrated into its design. All CEQA-related impacts are considered less than significant; hence the design features are not considered mitigation. Operational Design Features DF-1 The project will need to comply with California Title 24 building insulation requirements for exterior walls, roofs, and common separating assemblies 1-4 (e.g., floor/ceiling assemblies and demising walls), which shall be reviewed by the City prior to issuance of a building permit. • Interior noise levels due to exterior sources must not exceed a community noise equivalent level (CNEL) or a day-night level (LDN) of 45 dBA, in any habitable room. • Party wall assembly designs must provide a minimum STC of 50, based on lab tests. Field tested assemblies must provide a minimum noise isolation class (NIC) of 45. DF-2 A “windows closed” condition is expected to be required for all residential units within the project site to meet the interior noise standard. To accommodate windows closed conditions, all units shall be equipped with adequate fresh air ventilation, per the requirements of the California Building Standards. DF-3 Upgraded windows and sliding glass doors with a minimum STC rating of 32 or greater are expected to be required for all units facing Cambridge Street and Katella Avenue. DF-4 Deliveries, loading and unloading activities, and trash pick-up hours should be limited to daytime hours only (7 a.m. – 10 p.m.). DF-5 Engine idling time for all delivery vehicles and moving trucks to 5 minutes or less. Construction Design Features DF-6 Construction-related noise shall take place only between the hours of 7:00 a.m. to 8:00 p.m. Monday through Saturday, and 9:00 a.m. to 8:00 p.m. on Sundays and Federal holidays. DF-7 Provide public notifications and signage in readily visible locations along the perimeter of construction sites that indicate the dates and duration of construction activities, as well as provide a telephone number where neighbors can enquire about the construction process and register complaints to a designated construction noise disturbance coordinator. 1-5 DF-8 All construction equipment shall be equipped with muffles and other suitable noise attenuation devices (e.g., engine shields). DF-9 Establish an electric connection to the site to avoid the use of diesel- and gas-powered generators, if feasible. DF-10 Locate staging area, generators, and stationary construction equipment as far from the adjacent residential homes as feasible. DF-11 Construction-related equipment, including heavy-duty equipment, motor vehicles, and portable equipment, shall be turned off when not in use for more than 5 minutes. 2-1 2.0 Fundamentals of Noise and Vibration This section of the report provides basic information about noise and vibration and presents some of the terms used in the report. 2.1 Sound, Noise, and Acoustics The sound is a disturbance created by a moving or vibrating source and is capable of being detected by the hearing organs. The sound may be thought of as the mechanical energy of a moving object transmitted by pressure waves through a medium to a human ear. For traffic or stationary noise, the medium of concern is air. Noise is defined as sound that is loud, unpleasant, unexpected, or unwanted. 2.2 Frequency and Hertz A continuous sound is described by its frequency (pitch) and its amplitude (loudness). Frequency relates to the number of pressure oscillations per second. Low-frequency sounds are low in pitch (bass sounding) and high-frequency sounds are high in pitch (squeak). These oscillations per second (cycles) are commonly referred to as Hertz (Hz). The human ear can hear from the bass pitch starting out at 20 Hz all the way to the high pitch of 20,000 Hz. 2.3 Sound Pressure Levels and Decibels The amplitude of a sound determines its loudness. The loudness of sound increases or decreases, as the amplitude increases or decreases. Sound pressure amplitude is measured in units of micro-Newton per square inch meter (N/m2), also called micro-Pascal (μPa). One μPa is approximately one hundred billionths (0.00000000001) of normal atmospheric pressure. Sound pressure level (SPL or Lp) is used to describe in logarithmic units the ratio of actual sound pressures to a reference pressure squared. These units are called decibels and abbreviated as dB. 2.4 Addition of Decibels Because decibels are on a logarithmic scale, sound pressure levels cannot be added or subtracted by simple plus or minus addition. When two (2) sounds of equal SPL are combined, they will produce an SPL 3 dB greater than the original single SPL. In other words, sound energy must be doubled to produce a 3dB increase. 2-2 If two (2) sounds differ by approximately 10 dB the higher sound level is the predominant sound. 2.5 Human Response to Changes in Noise Levels1 In general, the healthy human ear is most sensitive to sounds between 1,000 Hz and 5,000 Hz, (A-weighted scale) and it perceives a sound within that range as being more intense than a sound with a higher or lower frequency with the same magnitude. For purposes of this report as well as with most environmental documents, the A-scale weighing is typically reported in terms of A-weighted decibel (dBA). Typically, the human ear can barely perceive the change in the noise level of 3 dB. A change in 5 dB is readily perceptible, and a change in 10 dB is perceived as being twice or half as loud. As previously discussed, a doubling of sound energy results in a 3 dB increase in sound, which means that a doubling of sound energy (e.g. doubling the volume of traffic on a highway), would result in a barely perceptible change in sound level. 2.6 Noise Descriptors Noise in our daily environment fluctuates over time. Some noise levels occur in regular patterns, others are random. Some noise levels are constant, while others are sporadic. Noise descriptors were created to describe the different time-varying noise levels. Following are the most commonly used noise descriptors along with brief definitions. A-Weighted Sound Level The sound pressure level in decibels as measured on a sound level meter using the A-weighted filter network. The A-weighting filter de-emphasizes the very low and very high-frequency components of the sound in a manner similar to the response of the human ear. A numerical method of rating human judgment of loudness. Ambient Noise Level The composite of noise from all sources, near and far. In this context, the ambient noise level constitutes the normal or existing level of environmental noise at a given location. 1 Technical Noise Supplement to the Traffic Noise Analysis Protocol, September 2013. 2-3 Community Noise Equivalent Level (CNEL) The average equivalent A-weighted sound level during a 24-hour day, obtained after the addition of five (5) decibels to sound levels in the evening from 7:00 to 10:00 PM and after the addition of ten (10) decibels to sound levels in the night before 7:00 AM and after 10:00 PM. Decibel (dB) A unit for measuring the amplitude of a sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micro-pascals. dB(A) A-weighted sound level (see definition above). Equivalent Sound Level (LEQ) The sound level corresponding to a steady noise level over a given sample period with the same amount of acoustic energy as the actual time-varying noise level. The energy average noise level during the sample period. Habitable Room Any room meeting the requirements of the Uniform Building Code or other applicable regulations which is intended to be used for sleeping, living, cooking or dining purposes, excluding such enclosed spaces as closets, pantries, bath or toilet rooms, service rooms, connecting corridors, laundries, unfinished attics, foyers, storage spaces, cellars, utility rooms, and similar spaces. L(n) The A-weighted sound level exceeded during a certain percentage of the sample time. For example, L10 in the sound level exceeded 10 percent of the sample time. Similarly, L50, L90, and L99, etc. 2-4 Noise Any unwanted sound or sound which is undesirable because it interferes with speech and hearing, is intense enough to damage hearing, or is otherwise annoying. The State Noise Control Act defines noise as “...excessive undesirable sound...”. Percent Noise Levels See L(n). Sound Level (Noise Level) The weighted sound pressure level obtained by use of a sound level meter having a standard frequency-filter for attenuating part of the sound spectrum. Sound Level Meter An instrument, including a microphone, an amplifier, an output meter, and frequency weighting networks for the measurement and determination of noise and sound levels. Single Event Noise Exposure Level (SENEL) The dBA level which, if it lasted for one (1) second, would produce the same A-weighted sound energy as the actual event. 2.7 Sound Propagation As sound propagates from a source it spreads geometrically. The sound from a small, localized source (i.e., a point source) radiates uniformly outward as it travels away from the source in a spherical pattern. The sound level attenuates at a rate of 6 dB per doubling of distance. The movement of vehicles down a roadway makes the source of the sound appear to propagate from a line (i.e., line source) rather than a point source. This line source results in the noise propagating from a roadway in a cylindrical spreading versus a spherical spreading that results from a point source. The sound level attenuates for a line source at a rate of 3 dB per doubling of distance. As noise propagates from the source, it is affected by the ground and atmosphere. Noise models use the hard site (reflective surfaces) and soft site (absorptive surfaces) to help calculate predicted noise levels. Hard site conditions assume no excessive ground 2-5 absorption between the noise source and the receiver. Soft site conditions such as grass, soft dirt or landscaping attenuate noise at an additional rate of 1.5 dB per doubling of distance. When added to the geometric spreading, the excess ground attenuation results in an overall noise attenuation of 4.5 dB per doubling of distance for a line source and 6.0 dB per doubling of distance for a point source. Research has demonstrated that atmospheric conditions can have a significant effect on noise levels when noise receivers are located 200 feet and greater from a noise source. Wind, temperature, air humidity, and turbulence can further impact how far sound can travel. Figure 1 shows typical sound levels from indoor and outdoor noise sources. 2-6 Figure 12 2 Technical Noise Supplement to the Traffic Noise Analysis Protocol, September 2013. 2-7 2.8 Vibration Descriptors Ground-borne vibrations consist of rapidly fluctuating motions within the ground that have an average motion of zero. The effects of ground-borne vibrations typically only cause a nuisance to people, but at extreme vibration levels, damage to buildings may occur. Although ground-borne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects of the shaking of a building can be notable. Ground-borne noise is an effect of ground-borne vibration and only exists indoors since it is produced from noise radiated from the motion of the walls and floors of a room and may also consist of the rattling of windows or dishes on shelves. Several different methods are used to quantify vibration amplitude. PPV Known as the peak particle velocity (PPV) which is the maximum instantaneous peak in vibration velocity, typically given in inches per second. RMS Known as the root mean squared (RMS) can be used to denote vibration amplitude. VdB A commonly used abbreviation to describe the vibration level (VdB) for a vibration source. 2.9 Vibration Perception Typically, developed areas are continuously affected by vibration velocities of 50 VdB or lower. These continuous vibrations are not noticeable to humans whose threshold of perception is around 65 VdB. Outdoor sources that may produce perceptible vibrations are usually caused by construction equipment, steel-wheeled trains, and traffic on rough roads, while smooth roads rarely produce perceptible ground-borne noise or vibration. To counter the effects of ground-borne vibration, the Federal Transit Administration (FTA) has published guidance relative to vibration impacts. 2-8 2.10 Vibration Propagation There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wavefront, similar to ripples produced by throwing a rock into a pool of water. P-waves, or compression waves, are body waves that carry their energy along an expanding spherical wavefront. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. S-waves, or shear waves, are also body waves that carry energy along an expanding spherical wavefront. However, unlike P-waves, the particle motion is transverse, or side-to-side and perpendicular to the direction of propagation. As vibration waves propagate from a source, the vibration energy decreases in a logarithmic nature and the vibration levels typically decrease by 6 VdB per doubling of the distance from the vibration source. As stated above, this drop-off rate can vary greatly depending on the soil but has been shown to be effective enough for screening purposes, in order to identify potential vibration impacts that may need to be studied through actual field tests. 2.11 Construction Related Vibration Level Propagation3 Operational activities are separated into two different categories. The vibration can be transient or continuous in nature. Each category can result in varying degrees of ground vibration, depending on the equipment used on the site. Operation of equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Buildings in the vicinity of the project area site respond to these vibrations with varying results ranging from no perceptible effects at the low levels to slight damage at the highest levels. The thresholds from Caltrans Transportation and Construction Vibration Guidance Manual, April 2020, in the table below provide general guidelines as to the maximum vibration limits for when vibration becomes potentially annoying. 3 Caltrans Transportation and Construction Vibration Guidance Manual, April 2020 2-9 Table 3 Vibration Annoyance Potential Criteria Human Response PPV (in/sec) Transient Sources Continuous/Frequent Intermittent Sources Barely perceptible 0.04 0.01 Distinctly perceptible 0.25 0.04 Strongly perceptible 0.90 0.10 Severe 2.00 0.40 Note: Transient sources create a single isolated vibration event, such as blasting or drop balls. Continuous/frequent intermittent sources include impact pile drivers, pogo- stick compactors, crack-and-seat equipment, vibratory pile drivers, and vibratory compaction equipment. The Caltrans Transportation and Construction Vibration Guidance Manual, April 2020 provides general thresholds and guidelines as to the vibration damage potential from vibratory impacts. The table below provides general vibration damage potential thresholds: Table 4 Vibration Damage Potential Threshold Criteria Structure and Condition PPV (in/sec) Transient Sources Continuous/Frequent Intermittent Sources Extremely fragile historic buildings ruin ancient monuments 0.12 0.08 Fragile buildings 0.20 0.10 Historic and some old buildings 0.50 0.25 Older residential structures 0.50 0.30 New residential structures 1.00 0.50 Modern industrial/commercial buildings 2.00 0.50 Soil conditions have an impact on how vibration propagates through the ground. The Caltrans Transportation and Construction Vibration Guidance Manual, April 2020 provides suggested “n” values based on soil class. The table below outlines the manual’s suggested values and description. 2-10 Table 5 Suggested “n” Values Based on Soil Classes Soil Class Description of Soil Material Suggested Value of “n” I Weak or soft soils: loose soils, dry or partially saturated peat and muck, mud, loose beach sand, and dune sand. 1.4 II Most sands, sandy clays, silty clays, gravel, silts, and weathered rock. 1.3 III Hard soils: densely compacted sand, dry consolidated clay, consolidated glacial till, and some exposed rock. 1.1 IV Hard, component rock: bedrock, freshly exposed hard rock. 1.0 3-1 3.0 Regulatory Setting The proposed project is located in the City of Orange and noise regulations are addressed through the various federal, state, and local government agencies. The agencies responsible for regulating noise are discussed below. 3.1 Federal Regulations The adverse impact of noise was officially recognized by the federal government in the Noise Control Act of 1972, which serves three (3) purposes: • Publicize noise emission standards for interstate commerce • Assist state and local abatement efforts • Promote noise education and research The Federal Office of Noise Abatement and Control (ONAC) was originally tasked with implementing the Noise Control Act. However, it was eventually eliminated leaving other federal agencies and committees to develop noise policies and programs. Some examples of these agencies are as follows: The Department of Transportation (DOT) assumed a significant role in noise control through its various agencies. The Federal Aviation Agency (FAA) is responsible to regulate noise from aircraft and airports. The Federal Highway Administration (FHWA) is responsible to regulate noise from the interstate highway system. The Occupational Safety and Health Administration (OSHA) is responsible for the prohibition of excessive noise exposure to workers. The Federal government and the State advocate that local jurisdiction use their land use regulatory authority to arrange new development in such a way that “noise sensitive” uses are either prohibited from being constructed adjacent to a highway or, or alternatively that the developments are planned and constructed in such a manner that potential noise impacts are minimized. Since the Federal government and the State have preempted the setting of standards for noise levels that can be emitted by the transportation source, the City is restricted to regulating the noise generated by the transportation system through nuisance abatement ordinances and land use planning. 3-2 3.2 State Regulations The State of California has established noise insulation standards as outlined in Title 24 of the Building Standards Code which in some cases requires acoustical analyses to outline exterior noise levels and to ensure interior noise levels do not exceed the interior threshold. Noise insulation design standards for residential dwellings are established in the 2019 California Building Code, Title 24, Part 2, Volume 1, Section 1206 Sound Transmission. The City is required by the State Housing Law to adopt these State codes as minimum performance standards. The City may enact stricter noise standards throughout the city or on a case-by-case basis if deemed necessary. In brief, the Title 24 noise standards require the following for allowable interior noise levels: 1. Interior noise levels due to exterior sources must not exceed a community noise equivalent level (CNEL) or a day-night level (LDN) of 45 dBA, in any habitable room. 2. Party wall and floor-ceiling assembly designs must provide a minimum STC of 50, based on lab tests. Field tested assemblies must provide a minimum noise isolation class (NIC) of 45. 3. Floor-ceiling assembly designs must provide for a minimum impact insulation class (IIC) of 50, based on lab tests. Field tested assemblies must provide a minimum FIIC of 45. 4. Penetrations or openings in sound rated assemblies must be treated to maintain required ratings. 3.3 City of Orange Noise Regulations The City of Orange outlines its noise regulations and standards within Chapter 8.24 of the Orange Municipal Code and the City of Orange General Plan Noise Element. Noise impacts can be identified into two types based on their sources: mobile or stationary. The noise metrics used for mobile sources, such as transportation-related noise (e.g., freeways, airports, and railroads) are the Community Noise Equivalent Level (CNEL), which is a 24- hour time-weighted average noise level. Stationary noise sources, such as industrial or construction noise, that may be intrusive to a neighboring private property utilize the noise metrics that are defined as noise levels that cannot be exceeded for certain percentages of time. 3-3 The noise standards from the City’s General Plan and Municipal Code are provided in Appendix A. 3.3.1 City of Orange Stationary Noise Standards The City of Orange’s daytime and nighttime noise standards for fixed noise sources are defined in the City’s General Plan. Table 6 below states the City of Orange’s maximum allowable noise exposure from stationary sources. Table 6 City of Orange Stationary Noise Standards Noise Level Descriptor Daytime (7:00 a.m. to 10:00 p.m.) Nighttime (10:00 p.m. to 7:00 a.m.) Hourly Equivalent Level 55 45 Maximum Level 70 65 Source: City of Orange General Plan Noise Element, Table N-4 Notes: 1. These standards apply to new or existing noise sensitive land uses affected by new or existing non- transportation noise sources, as determined at the outdoor activity area of the receiving land use. However, these noise level standards do not apply to residential units established in conjunction with industrial or commercial uses (e.g., caretaker dwellings). 2. Each of the noise levels specified above should be lowered by five dB for simple tone noises, noises consisting primarily of speech or music, or for recurring impulsive noises. Such noises are generally considered by residents to be particularly annoying and are a primary source of noise complaints. These noise level standards do not apply to residential units established in conjunction with industrial or commercial uses (e.g. caretaker dwellings). 3. No standards have been included for interior noise levels. Standard construction practices that comply with the exterior noise levels identified in this table generally result in acceptable interior noise levels. 4. The City may impose noise level standards which are more or less restrictive than those specified above based upon determination of existing low or high ambient noise levels. If the existing ambient noise level exceeds the standards listed in Table N-4, then the noise level standards shall be increased at 3 dB increments to encompass the ambient environment. Noise level standards incorporating adjustments for existing ambient noise levels shall not exceed a maximum of 70 dB Leq. 3-4 3.3.2 Land Use Compatibility Standards The City of Orange has developed land use compatibility standards to determine ambient noise levels that are considered “normally acceptable” for their respective land uses. These standards are applicable to transportation-related noise sources. Table 7 below states the noise standards applicable to the proposed project’s land use, as described in the City’s General Plan. Table 7 City of Orange Land Use Compatibility Standards Land Use CNEL (dBA) Designations Uses Interior1, 3 Exterior2 Medium Density Residential Neighborhood4, 5 Multiple-family, mixed-use 45 65 Source: City of Orange General Plan Noise Element, Table N-3. Notes: 1. Interior habitable environment excludes bathrooms, closets and corridors. 2. Exterior noise level standard to be applied at outdoor activity areas; such as private yards, private patio or balcony of a multi-family residence. Where the location of an outdoor activity area is unknown or not applicable, the noise standard shall be applied inside the property line of the receiving land use. 3. Interior noise standards shall be satisfied with windows in the closed position. Mechanical ventilation shall be provided per California Building Standards Code requirements. 4. Within the urban Mixed-Use, Neighborhood Mixed-Use, Old Towne Mixed-Use, and Medium Density Residential land use designations, exterior space standards apply only to common outdoor recreational areas. 5. Within Urban Mixed-Use and Medium Density Residential land use designations, exterior noise levels on private patios or balconies located within 250 feet of freeways (I-5, SR-57, SR-22, or SR-241) and Smart Streets and Principal Arterials identified in the Circulation & Mobility Element that exceed 70 dB should provide additional common open space. 3-5 3.3.3 City of Orange Construction Noise Regulation Section 8.24.050, Exemptions from Chapter Revisions, of the City’s municipal code lists construction-related noise as exempt from exterior noise standards under the following conditions: • Noise sources associated with construction, repair, remodeling, or grading of any real property . . . take place between the hours of 7:00 a.m. and 8:00 p.m. on any day except for Sunday or a Federal holiday, or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday or a Federal holiday. Noise generated outside of the hours specified are subject to the noise standards identified in Table 8.24.040. 3.3.4 City of Orange Noise Level Thresholds of Significance The City of Orange General Plan Noise Element outlines the following additional thresholds of significance for examining noise impacts under CEQA: For City analysis of noise impacts and determining appropriate mitigation under the California Environmental Quality Act (CEQA), in addition to the maximum allowable noise level standards outlined in Tables N-3 and N-4, an increase in ambient noise levels is assumed to be a significant noise impact if a project causes ambient noise levels to exceed the following: • Where the existing ambient noise level is less than 65 dBA, a project related permanent increase in ambient noise levels of 5 dBA CNEL or greater. • Where the existing ambient noise level is greater than 65 dBA, a project related permanent increase in ambient noise levels of 3 dBA CNEL or greater. 4-1 4.0 Study Method and Procedures The following section describes the measurement procedures, measurement locations, and noise modeling procedures and assumptions used in the noise analysis. 4.1 Measurement Procedures and Criteria Noise measurements are taken to determine the existing noise levels. A noise receiver or receptor is any location in the noise analysis in which noise might produce an impact. The following criteria are used to select measurement locations and receptors: • Locations expected to receive the highest noise impacts, such as the first row of houses • Locations that are acoustically representative and equivalent of the area of concern • Human land usage • Sites clear of major obstruction and contamination RK conducted the sound level measurements in accordance with Caltrans technical noise specifications. All measurement equipment meets American National Standards Institute (ANSI) specifications for sound level meters (ANSI S1.4: Specification for Sound Level Meter, 1983) Piccolo-II Type 2 integrating-averaging level meters were used to conduct long-term (24- hour) noise measurements at the project site. The Leq, Lmin, Lmax, L2, L8, L25, and L50 statistical data were recorded over the measurement time period intervals and the information was utilized to define the noise characteristics for the project. The following gives a brief description of the Caltrans Technical Noise Supplement procedures for sound level measurements: • Microphones for sound level meters were placed five (5) feet above the ground for long-term noise measurements • Sound level meters were calibrated before and after each measurement • Following the calibration of equipment, a windscreen was placed over the microphone • Frequency weighting was set on “A” and slow response • Temperature and sky conditions were observed and documented 4-2 Appendix B includes photos, field sheets, and measured noise data. 4.2 Stationary Noise Modeling On-site stationary noise sources were analyzed using SoundPLAN™ noise modeling software. SoundPLAN™ is a standards-based program that incorporates more than twenty national and international noise modeling guidelines. This project consists of parking lot noise and stationary noise sources which are classified under industrial sources. Projected noise levels from SoundPLAN™ are based on the following key parameters: • Developing three-dimensional noise models of the project, • Predicting the project noise levels at the selected community locations and • Comparing the predicted noise with the existing community ambient noise levels at the receptor locations. The sides of the buildings, walls, etc. were modeled as reflective surfaces and also as diffractive bodies. The noise sources are shown as red spheres (point sources) and red surfaces (area sources). A light blue line outlines the perimeter of each operation. The surrounding roads are displayed as grey surfaces. Most of the ground within the project site and adjacent areas are covered with paved surfaces and lawns and will be run as a hard site to be conservative (Ground Factor=0). The Effective Flow Resistivity for field grass is SoundPLAN default. The elevation profile for the project site is derived from Google Earth and all the receptors are placed at 5 feet above ground level. Sound Power and Sound Pressure Level Sound power level is the acoustic energy emitted by a source that produces a sound pressure level at some distance. While the sound power level of a source is fixed, the sound pressure level depends upon the distance from the source and the acoustic characteristics of the area in which it is located. SoundPLAN requires that the source noise level be input using sound power level and which must be back-calculated based on a measured sound pressure level. The sound power level is calculated using SoundPLAN software by calibrating the source noise level to equal the sound pressure level at an equal distance from the source in which the referenced measurement was taken. 4-3 4.2.1 HVAC Equipment Noise This analysis assumes each dwelling unit will be equipped with residential HVAC equipment. Table 8 indicated the referenced noise levels for on-site stationary noise sources. Table 8 HVAC Referenced Noise Levels1 Source1 Noise Levels (dBA) Leq HVAC Equipment 73.2 1Referenced noise levels are based on typical residential HVAC equipment observed by RK. To estimate the future noise levels during typical operational conditions, referenced noise levels are input into SoundPLAN and projected to the nearest sensitive receptor locations. Adjusted noise levels are based on the distance of the receptor location relative to the noise source, local topography, and physical barriers including buildings and sound walls. The noise levels assume that the stationary sources are operating continuously during both daytime and nighttime hours, when in reality will likely operate only intermittently throughout daily operations. 4.2.2 Parking Lot Noise Parking lot noise would occur from vehicles and trucks entering and exiting the site, idling, exhaust, loading and delivery activities, doors slamming, tires screeching, people talking, and the occasional horn honking. Parking lot noise would occur throughout the site and is assessed by using referenced noise levels in the SoundPLAN model. Parking lot noise is based on the type of vehicle and the number of movements per hour. Referenced noise levels for parking lot activities are based on the SoundPLAN™ standard Parkplatzlärmstudie 2007. Key inputs for parking lot noise include the size of the area source, number of movements per hour, type of vehicles, and number of parking spaces within each lot. 4.3 Construction Noise Modeling The construction noise analysis utilizes the Federal Highway Administration (FHWA) Roadway Construction Noise Model, together with several key construction parameters. Key inputs include distance to the sensitive receiver, equipment usage, and baseline parameters for the project site. This study evaluates the potential exterior noise impacts during each phase of construction. 4-4 Noise levels were projected at an average distance of 50 feet for equipment operating over a 8-hour period from the nearest sensitive receptor property line. While some construction noise activity may occur closer than 50 feet from the property line, noise levels are averaged over a 8-hour period for purposes of assessing impacts. The methodology used for assessing construction noise impacts is consistent with the Federal Transit Administration Transit Noise and Vibration Impact Assessment Manual, September 20184. 4.4 Construction Vibration Modeling The construction vibration assessment is based on the methodology set forth within the Caltrans Transportation and Construction Induced Vibration Guidance Manual. The vibration impacts from vibratory rollers and compactors, heavy truck loading, and bulldozer activity are analyzed. All vibratory activity is analyzed as a continuous and/or frequent event and is required to comply with the applicable guidance threshold criteria. It is expected that vibration levels will be highest during the paving phase. No impact pile driving is expected as part of this project. Vibratory impacts were calculated from the site area property line to the closest sensitive receptors and structures using the reference vibration levels, soil conditions, and the reference equation PPV= PPV ref (25/D)^n (in/sec) (from Caltrans Manual) where: PPV = reference measurement at 25 feet from vibration source D = distance from equipment to property line n= vibration attenuation rate through ground (n=1.0 was utilized for this study) 4 Federal Transit Administration. Transit Nosie and Vibration Impact Assessment Manual. September 2018. Section 7.1. Construction Noise Assessment. 5-1 5.0 Existing Noise Environment The existing noise environment for the project site and surrounding areas has been established based on noise measurement data collected by RK. Noise measurement data indicates that the ambient noise consists primarily of traffic noise propagating from the adjacent roadways, as well as activities from the surrounding properties. 5.1 24-Hour Noise Measurement Results In order to establish the ambient noise environment, RK conducted three (3) 24-hour noise measurements at the project study area. Noise levels were measured on September 14, 2022 using Piccolo-II Type 2 integrating- averaging sound level meters. The information was utilized to establish the noise characteristics of the existing ambient environment The noise monitoring locations were selected based on the proximity and location of adjacent sensitive receptors. Exhibit C graphically illustrates the location of the long-term measurements. • Noise monitoring location one (L-1) was taken approximately 100 feet north of the centerline of Katella Avenue and 115 feet east of the centerline of N. Cambridge Street. • Noise monitoring location two (L-2) was taken approximately 70 feet east of the centerline of Cambridge Street and approximately 20 feet south of the project site’s northern property line. • Noise monitoring location three (L-3) was taken approximately 300 feet east of the centerline of Cambridge Street and 10 feet south of the project site’s northern property line. Noise monitoring locations represent the existing ambient noise levels near the adjacent noise-sensitive land uses and the project site. Appendix B includes photographs, field sheets, and measured noise data. Noise measurements are summarized in Table 9, Table 10, and Table 11 below. 5-2 Table 9 24 Noise Measurement Results, L-11 Time Leq (dBA) Time Leq (dBA) 12:00 AM 59.1 12:00 PM 68.2 1:00 AM 56.0 1:00 PM 66.6 2:00 AM 57.1 2:00 PM 66.7 3:00 AM 60.7 3:00 PM 67.5 4:00 AM 63.7 4:00 PM 68.3 5:00 AM 65.6 5:00 PM 68.2 6:00 AM 68.2 6:00 PM 67.5 7:00 AM 68.9 7:00 PM 67.4 8:00 AM 69.3 8:00 PM 67.1 9:00 AM 68.0 9:00 PM 64.3 10:00 AM 66.4 10:00 PM 63.0 11:00 AM 66.2 11:00 PM 60.8 24-Hour CNEL 71.0 1 L-1 was taken approximately 100 feet north of the centerline of E.

The main sources of noise generated by the project would include on-site operational activities from HVAC equipment and parking lot noise. Noise level impacts are compared to the City of Orange noise standards. The project must demonstrate that noise levels generated by the project site would not be in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. 6.1 Operational Noise Source Impacts 6.1.1 Stationary Noise Source Impacts On-site stationary noise impacts are assessed at all adjacent sensitive receptor property lines surrounding the project site. Existing sensitive land uses surrounding the proposed project site include existing residential uses to the north and northwest. Project operational activities are analyzed for long-term noise impacts associated with the day-to-day operation of the project; including mechanical HVAC equipment and on-site vehicular movements to the nearest adjacent property lines. The project is proposing to build a noise barrier wall (minimum six (6) feet high) along the eastern property line. An existing six (6) foot tall noise barrier wall is located along the northern property line. The noise study has taken the proposed and existing wall locations into account for potential noise barrier shielding. HVAC equipment will be located at ground level on the side yards of the homes. On-site vehicular noise would occur from vehicle engine idling and exhaust, doors slamming, tires screeching, people talking, and the occasional horn honking. Vehicular noise is expected to occur throughout the project site. SoundPLAN calculation worksheets are shown in Appendix C. Project daytime and nighttime noise level contours are graphically illustrated in Exhibits E and F, respectively. 6-2 Daytime Stationary Source Noise Impacts The results of the daytime noise impact analysis are shown in Table 12 and are graphically illustrated in Exhibit D. The noise analysis considers all project noise sources operating simultaneously during daytime (7:00 a.m. to 10:00 p.m.) hours at the nearest sensitive receptors. Table 12 Typical Operation Noise Levels (dBA) - Daytime Receptor Location Daytime Exterior Noise Level dBA Existing Ambient Noise Level1 Project Noise Level Existing + Project Noise Level Change as a result of project City of Orange Daytime Noise Level Standard (Leq) Project Noise Level Exceeds Standard (?)

Based on the results of this analysis, noise levels generated by the project are not expected to exceed the City of Orange’s daytime noise standards at the adjacent property lines. 6. Nighttime Stationary Source Noise Impacts The results of the nighttime noise impact analysis are shown in Table 13 and are graphically illustrated in Exhibit D. The nighttime noise analysis considers all project noise sources operating simultaneously during nighttime (10:00 p.m. to 7:00 a.m.) hours at the nearest sensitive receptors. 6-3 Table 13 Typical Operation Noise Levels (dBA) - Nighttime Receptor Location Daytime Exterior Noise Level dBA (Leq) Existing Ambient Noise Level1 Project Noise Level Existing + Project Noise Level Change as a result of project City of Orange Nighttime Noise Level Standard (Leq)2 Project Exceeds City Standard (yes/no) Significant Impact (yes/no)3 Receiver-1 Northwest 50.2 34.8 50.3 0.1 45.0 No No Receiver-2 North 46.0 44.5 48.3 2.3 No No Receiver-3 Northeast 46.0 36.2 46.4 0.4 No No 1 Existing ambient noise levels are the lowest average hourly Leq, and are representative of approximate noise levels at surrounding receptor locations. 2 Source: City of Orange General Plan Noise Element, Table N-4. 3 A significant impact would occur where there is an existing ambient noise level of less than 65 dBA and a project related permanent increase in ambient noise levels of 5 dBA CNEL or greater. Based on the results of this analysis, noise levels generated by the project are not expected to exceed the City of Orange’s nighttime noise standards at the adjacent property lines. 6.1.2 Roadway Noise Source Impacts The project is not expected to cause a substantial increase in ambient noise levels in the vicinity of the site as a result of increased traffic volume along adjacent roadways. Typically, it takes a doubling of traffic volume along a roadway to cause a significant increase in ambient noise levels of more than 3 dBA. The project is expected to generate approximately 374 average daily trips (ADT)5. Hence, the amount of traffic generated by the project will not double the amount of traffic along Cambridge Street or Katella Avenue, either directly or cumulatively, and therefore the increase in roadway noise levels as a result of the project is less than significant. The project’s impact from operational noise sources will be less than significant. 5 ADT volumes are referenced from 901 E. Katella Avenue In-Fill Residential Project (TTM 19253) Trip Generation Analysis, City of Orange, CA by RK Engineering Group, October 2022. 6-4 6.2 Noise/Land Use Compatibility The project will site new residential homes and outdoor recreational space within approximately 25 feet of the edges of the nearest travel lanes of Katella Avenue and Cambridge Street. Traffic noise from these roadways will be the primary source of noise impacting the project site and may expose future residents to noise levels above the State of California and City of Orange recommended limits for residential uses. The proposed project site is designated in the City’s General Plan as “Medium Density Residential Neighborhood,” and is listed as a “multiple-family” land use. The General Plan Noise Element states that for Medium Density Residential land uses, exterior noise standards apply only to common outdoor recreational areas, and do not apply to private patios or balconies. Therefore, this study only analyzes exterior noise levels for the project’s common recreational area (pocket park) and does not consider noise levels at private outdoor patios. The proposed on-site pocket park will be located near the northern boundary of the project site. This space will be considered a habitable outdoor area and will be required to comply with the City’s exterior noise standards for multi-family residential uses. Due to its location, the pocket park will be shielded from the line of sight of the adjacent roadways and the noise they produce. Therefore, it is assumed that the ambient noise levels at the pocket park will be within the City’s exterior noise standards. 6.3 Preliminary Interior Noise Analysis Based on the measured existing and projected exterior noise levels, future residents of the proposed project may be exposed to noise levels that exceed the City’s maximum allowable standards for interior noise exposure. Therefore, to ensure that interior noise levels fall within the “normally acceptable” range, the following preliminary interior noise analysis has been performed. The preliminary interior noise analysis has been prepared for the project’s on-site sensitive receptor locations (i.e., first rows of residential dwelling units) using a typical "windows open" and "windows closed" condition. A "windows open" condition assumes 12 dBA of noise attenuation from the exterior noise level. A "windows closed" condition" assumes 20 dBA of noise attenuation from the exterior noise level. Table 14 indicates the interior noise levels for the residential uses on the project site. 6-5 Table 14 Preliminary Interior Noise Impact Analysis Receptor Location Exterior Noise Level at Building Facade (CNEL) Interior Noise Standard1 (CNEL) Required Building Shell Noise Reduction (CNEL) Interior Noise Level with Standard California Construction Windows (STC > 25) STC Rating for Windows Facing Subject Roadway "Windows Open" 2 "Windows Closed" 3 1st Row Buildings Facing Adjacent Roadways 74.0 45.0 29.0 62.0 54.0 32.0 1Source: City of Orange General Plan Noise Element, Table N-3. 2A minimum of 12 dBA noise reduction is assumed with the "windows open" condition. 3A minimum of 20 dBA noise reduction is assumed with the "windows closed" condition. The project is expected to require a “windows closed” condition, upgraded building construction, and upgraded STC-rated windows to meet the California Building Standards Code requirements for residential interior noise. To accommodate windows closed conditions, all units shall be equipped with adequate fresh air ventilation. Exterior walls, designed per the latest California Building Standards are typically rated between STC 35-40. In order to ensure adequate noise attenuation is provided from the building shell, exterior walls should be designed to meet the required sound attenuation targets. Attic vents and other openings should be baffled and oriented away from facing the adjacent roadways. Prior to issuance of building permits, the project proponent should demonstrate to the City Building Department that the proposed building shell and window assemblies will achieve exterior to interior noise reduction necessary to meet the State of California and City of Orange requirements. Furthermore, the project shall comply with California Title 24 insulation building requirements for multi-family dwelling units for common separating assemblies (e.g., floor/ceiling assemblies and demising walls). 6.4 Operation Project Design Features (DF) The following recommended project design features include standard rules and requirements, best practices, and recognized design guidelines for reducing noise levels. Design features are assumed to be part of the conditions of the project and integrated into its design. Design features are not typically considered mitigation under CEQA. 6-6 Operational Design Features DF-1 The project will need to comply with California Title 24 building insulation requirements for exterior walls, roofs, and common separating assemblies (e.g. floor/ceiling assemblies and demising walls), which shall be reviewed by the City prior to issuance of a building permit. • Interior noise levels due to exterior sources must not exceed a community noise equivalent level (CNEL) or a day-night level (LDN) of 45 dBA, in any habitable room. • Party wall assembly designs must provide a minimum STC of 50, based on lab tests. Field tested assemblies must provide a minimum noise isolation class (NIC) of 45. DF-2 A “windows closed” condition is expected to be required for all residential units within the project site to meet the interior noise standard. To accommodate windows closed conditions, all units shall be equipped with adequate fresh air ventilation, per the requirements of the California Building Standards. DF-3 Upgraded windows and sliding glass doors with a minimum STC rating of 32 or greater is expected to be required for all units facing Cambridge Street and Katella Avenue. DF-4 Deliveries, loading and unloading activities, and trash pick-up hours should be limited to daytime hours only (7 a.m. – 10 p.m.). DF-5 Engine idling time for all delivery vehicles and moving trucks to 5 minutes or less. 7-1 7.0 Construction Noise and Vibration Impacts Temporary construction noise and vibration impacts have been assessed from the project site to the surrounding existing noise-sensitive land uses. The degree of construction noise will vary depending on the type of construction activity taking place and the location of the activity relative to the surrounding properties. Section 8.24.050, Exemptions from Chapter Revisions, of the City’s municipal code lists construction-related noise as exempt from exterior noise standards under the following conditions: • Noise sources associated with construction, repair, remodeling, or grading of any real property . . . take place between the hours of 7:00 a.m. and 8:00 p.m. on any day except for Sunday or a Federal holiday, or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday or a Federal holiday. Noise generated outside of the hours specified is subject to the noise standards identified in Table 8.24.040. In compliance with the City’s Municipal Code, it is assumed construction would not occur during the noise-sensitive nighttime hours. 7.1 Typical Construction Noise Levels Table 15 shows typical construction noise levels compiled by the Environmental Protection Agency (EPA) for common-type construction equipment. Typical construction noise levels are used to estimate potential project construction noise levels at the adjacent sensitive receptors. 7-2 Table 15 Typical Construction Noise Levels1 Type Noise Levels (dBA) at 50 Feet Earth Moving Compactors (Rollers) 73 - 76 Front Loaders 73 - 84 Backhoes 73 - 92 Tractors 75 - 95 Scrapers, Graders 78 - 92 Pavers 85 - 87 Trucks 81 - 94 Materials Handling Concrete Mixers 72 - 87 Concrete Pumps 81 - 83 Cranes (Movable) 72 - 86 Cranes (Derrick) 85 - 87 Stationary Pumps 68 - 71 Generators 71 - 83 Compressors 75 - 86 Impact Equipment Pneumatic Wrenches 82 - 87 Jack Hammers, Rock Drills 80 - 99 Pile Drivers (Peak) 95-105 Other Vibrators 68 - 82 Saws 71 - 82 1 Referenced Noise Levels from the Environmental Protection Agency (EPA) 7.2 Construction Noise Impact Analysis This assessment analyzes potential noise impacts during all expected phases of construction, including demolition, site preparation, grading, building construction, paving, and architectural coating. Noise levels are calculated based on an average distance of equipment over an 8-hour period to the nearest adjacent property. The project’s estimated construction noise levels have been calculated using the Federal Highway Administration Roadway Construction Noise Model Version 1.1. Table 16 shows the noise level impacts at 100 feet. 7-3 Although construction activity is exempt from the noise standards in the City’s Municipal Code, the Federal Transit Administration (FTA) has provided guidelines for assessment of construction noise impacts in the Transit Noise And Vibration Impact Assessment Manual. For the purposes of this study, expected construction noise levels will be analyzed using the construction noise criteria provided by the FTA. Construction noise calculation worksheets are provided in Appendix D. 7-4 Table 16 Project Construction Noise Levels – at 100 Feet Phase Equipment Quantity Equipment Noise Level at 100ft Combined Noise Level (dBA Leq) (dBA Leq) Demolition Concrete Saw 1 83.6 85.2 Rubber Tired Dozers 1 75.7 Tractors/Loaders/Backhoes 1 78.0 Site Preparation Graders 1 79.0 83.0 Tractors/Loaders/Backhoes 1 78.0 Scraper 1 77.6 Grading Tractors/Loaders/Backhoes 2 78.0 83.8 Graders 1 79.0 Rubber Tired Dozers 1 75.7 Building Construction Cranes 1 74.6 81.9 Forklifts 2 69.0 Generator Sets 1 74.6 Tractors/Loaders/Backhoes 1 78.0 Welders 3 68.0 Paving Tractors/Loaders/Backhoes 1 78.0 82.0 Concrete Mixers 1 72.8 Pavers 2 71.2 Rollers 2 74.0 Architectural Coating Air Compressors 1 71.7 71.7 Worst Case Construction Phase Noise Level - Leq (dBA) 85.2 FTA Daytime General Assessment Construction Noise Criteria – Leq (dBA)1 90.0 1Source: Transit Noise and Vibration Impact Assessment Manual, Section 7 Noise and Vibration during Construction, by the Federal Transit Administration. The project is expected to generate a maximum noise level of 85.9 dBA. Based on the above table, the project’s construction-related noise levels will not exceed the FTA General Assessment Construction Noise Criteria threshold. 7-5 7.3 Construction Vibration To determine the vibratory impacts during construction, reference construction equipment vibration levels were utilized and then extrapolated to the façade of the nearest adjacent structures. The nearest sensitive receptors are the adjacent residential uses to the north of the project site. All structures surrounding the project site are “new structures”. No historical or fragile buildings are known to be located within the vicinity of the site. The construction of the proposed project is not expected to require the use of substantial vibration-inducing equipment or activities, such as pile drivers or blasting. The main sources of vibration impacts during the construction of the project would be the operation of equipment such as bulldozer activity during site preparation, loading trucks during grading and excavation, and vibratory rollers during paving. The construction vibration assessment utilizes the referenced vibration levels and methodology set forth within the Transit Noise and Vibration Impact Assessment Manual, Federal Transit Administration, September 2018. Table 17 shows the FTA-referenced vibration levels.

Construction vibration calculation worksheets are shown in Appendix D. 7.4 Construction Project Design Features The following recommended project design features include standard rules and requirements, best practices, and recognized design guidelines for reducing noise levels. Design features are assumed to be part of the conditions of the project and integrated into the site design and construction management plan. Construction Design Features DF-6 Construction noise is prohibited between the hours of 8:00 p.m. to 7:00 a.m., Monday through Saturday, and 6:00 p.m. to 10:00 a.m. on Sundays and federal holidays. DF-7 Provide public notifications and signage in readily visible locations along the perimeter of construction sites that indicate the dates and duration of 7-7 construction activities, as well as provide a telephone number where neighbors can enquire about the construction process and register complaints to a designated construction noise disturbance coordinator. DF-8 All construction equipment shall be equipped with muffles and other suitable noise attenuation devices (e.g., engine shields). DF-9 Establish an electric connection to the site to avoid the use of diesel- and gas-powered generators, if feasible. DF-10 Locate staging area, generators, and stationary construction equipment as far from the adjacent residential homes as feasible. DF-11 Construction-related equipment, including heavy-duty equipment, motor vehicles, and portable equipment, shall be turned off when not in use for more than 5 minutes.

GPA NO. 2014-0001 (12/2015) INTRODUCTION AND VISION FOR THE FUTURE The urban environment contains a variety of noise sources that can affect the way people live and work. Some types of noise are only short-term irritants, like the pounding of a jackhammer or the whine of a leaf blower. These noise sources can generally be controlled through City noise regulations, including noise ordinances. However, certain noises, such as freeway, road, aircraft, and train noise, may be permanent fixtures in the community, diminishing its quality of life. In Orange, because of its location, transportation corridors are the major source of noise. Orange’s Vision for the Future, presented in the General Plan introduction, includes the following objective related to the Noise Element:  The City will work to improve the quality of life for all residents by providing residential, commercial, industrial, and public uses that exist in harmony with the surrounding urban and natural environments. The Noise Element is a mandatory General Plan element, required by California’s Health and Safety Code Section 46050.01. The goal of the Noise Element is to identify problems and noise sources threatening community safety and comfort and to establish policies and programs that will limit the community’s exposure to excessive noise levels. It addresses both existing and foreseeable future noise abatement issues. Purpose of the Noise Element Recognizing that excessive or unusual noise can have significant adverse impacts on human health and welfare, the state has developed definitive guidelines for determining community noise levels and for establishing programs aimed at reducing community exposure to noise levels defined to be adverse. Policies, plans, and programs outlined within the Noise Element are designed to minimize the effects of human-caused noise in the community, and to improve residents’ quality of life by regulating and reducing noise, particularly within residential areas and near such noise-sensitive land uses as residences, hospitals, convalescent and day care facilities, schools, and libraries. The Element provides direction regarding best practices and strategies to protect City residents and businesses from severe noise levels. The Noise Element recognizes that multiple noise environments exist within the City, including rural, suburban, and urban environments. As Orange evolved from a rural agricultural town to a bustling suburban community in the middle to late 20th century, the noise environment similarly changed. Rural roads were replaced by the arterials and NOISE ORANGE GENERAL PLAN N-2 freeways present in Orange today. Relatively quiet suburban residential noise levels became the norm for most City residents. At the outset of the 21st century, Orange still has semi-rural areas in the eastern portions of the City, in addition to the suburban noise environment found in most of its residential neighborhoods and commercial areas. However, a noisier, more urban environment is now emerging in Uptown, and Land Use Element policies promote reinvention of certain City commercial corridors into mixed-use activity centers. At these mixed-use activity centers, residents, shoppers, and businesspeople alike may be exposed to higher noise levels due to traffic and human activity. Scope and Content of the Noise Element The Noise Element consists of three sections: (1) Introduction; (2) Issues, Goals, and Policies; and (3) Noise Plan. This Introduction summarizes the general purpose of the Noise Element. The Issues, Goals, and Policies section outlines the most relevant noise issues affecting the City. The goals are a statement of the general direction and broad ideals that capture the desire of the community. The policies provide potential solutions for decreasing noise. The Noise Plan defines noise standards, presents noise contour maps, and recommends strategies to achieve goals and implement policies. Implementation programs for the Noise Element are provided in an Appendix to the General Plan. The Noise Element addresses noise concerns that influence the comfort and quality of life of Orange residents. Excessive noise may originate from many sources, including vehicle traffic on freeways and arterial roadways, construction activities and machinery in industrial areas, railroads, and aircraft. Beyond direct mitigation strategies to address these sources of noise, the City is also committed to establishing and upholding guidelines for noise levels compatible with various types of land use activity. Mixed-use residential and commercial development presents unique noise reduction challenges. Although located in commercial environments, the residential portions of mixed- use projects are nonetheless subject to residential noise standards and guidelines established by the state. Strategies to address noise in these environments focus on incorporation of noise reducing measures in project design. Relationship to Other General Plan Elements Accomplishing the goals and policies of the Noise Element requires coordination with other related components of the City’s General Plan. Other topics that are affected by the Noise Element include the Land Use, Circulation & Mobility, and Housing Elements. Impacts of noise policies and programs on the Land Use Element arise during identification of noise sources and noise-sensitive uses. The noise contours and land use compatibility standards contained in the Noise Element should be used when making planning and development decisions. NOISE ORANGE GENERAL PLAN N-3 The contents of the Noise Element are also related to the Circulation & Mobility and Housing Elements, because Orange’s primary noise sources include freeways, arterial roadways, railways, and aircraft. In turn, Noise Element policies are intended to mitigate excessive noise along transportation routes and direct housing to appropriate sites away from sources of excessive noise. ISSUES, GOALS AND POLICIES Certain areas of Orange are subject to high levels of noise from one or more of the following sources: freeways and arterial roadways, construction activities and machinery in industrial areas, railroads, aircraft, and fireworks noise from nearby Disneyland and Angel Stadium. All of these noise sources reduce the quality of life within the City. Considering noise sources in the planning process, identifying the noise impacts of potential development projects, and planning accordingly are effective methods of minimizing the impacts of noise on residents. The goals, policies, and implementation programs of the Noise Element address seven issues: (1) noise and land use compatibility; (2) vehicular traffic noise; (3) train noise; (4) aircraft noise; (5) noise associated with mixed-use development; (6) industrial noise; and (7) construction, maintenance, and nuisance noise. Noise and Land Use Compatibility Land use directly affects noise compatibility, because higher noise levels often associated with industrial, commercial, and mixed commercial and residential development can encroach upon more noise-sensitive land uses. Noise-sensitive land uses include: residences, hospitals, convalescent and day care facilities, schools, and libraries. Noise producing and noise-sensitive land uses should be either sufficiently separated or sufficiently buffered from one another to ensure that sensitive uses are not exposed to unacceptable noise levels. Proposed land uses should be compatible with existing and forecasted future noise levels. Incompatible land use noise exposures should incorporate noise attenuation and/or control measures within project design to reduce the noise to an acceptable interior level of 45 A- weighted decibels (dBA) community noise equivalent level (CNEL) or lower, as required by state regulations (CCR Title 24) for residential uses. (For an explanation of these terms and the relative noise levels of common noise-producing activities, see the discussion accompanying Table N-2 in the “Measuring Noise” section that follows.) GOAL 1.0: Promote a pattern of land uses compatible with current and future noise levels. Policy 1.1: Consider potential excessive noise levels when making land use planning decisions. Policy 1.2: Encourage new development projects to provide sufficient spatial buffers to separate excessive noise generating land uses and noise-sensitive land uses. Policy 1.3: Incorporate design features into residential and mixed-use projects that can be used to shield residents from excessive noise. Policy 1.4: Ensure that acceptable noise levels are maintained near noise-sensitive uses. Policy 1.5: Reduce impacts of high-noise activity centers located near residential areas. NOISE ORANGE GENERAL PLAN N-4 Policy 1.6: Require an acoustical study for proposed developments in areas where the existing and projected noise level exceeds or would exceed the maximum allowable levels identified in Table N-3. The acoustical study shall be performed in accordance with the requirements set forth within this Noise Element. Vehicular Traffic Noise Vehicular traffic is the most common source of noise experienced throughout the City. Primary sources of traffic noise include: the Interstate 5 and State Route (SR) -22, -55, -57, and -91 Freeways which surround and traverse the City; the SR-241/261 Foothill Transportation Corridor; and City arterial roadways. Arterials such as State College Boulevard/The City Drive, Chapman Avenue, La Veta Avenue, Batavia Street, Glassell Street, Tustin Street, Katella Avenue, and Jamboree Road are all high traffic volume roadways that generate traffic noise levels well above 65 dBA CNEL. Traffic noise is dependent on vehicle volume, speed, flow, and fleet mix, as well as distance from the roadway to the receptor. GOAL 2.0: Minimize vehicular traffic noise in residential areas and near noise-sensitive land uses. Policy 2.1: Encourage noise-compatible land uses along existing and future roadways, highways, and freeways. Policy 2.2: Encourage coordinated site planning and traffic control measures that minimize traffic noise in noise-sensitive land use areas. Policy 2.3: Encourage the use of alternative transportation modes such as walking, bicycling, mass transit, and alternative fuel vehicles to minimize traffic noise. Policy 2.4: Continue to work with the California Department of Transportation (Caltrans), the Orange County Transit Authority (OCTA), and Transportation Corridor Agencies (TCA) to install, maintain, and update freeway and highway rights-of-way buffers and soundwalls. Policy 2.5: Work toward understanding and reducing traffic noise in residential neighborhoods with a focus on analyzing the effects of traffic noise exposure throughout the City. Train Noise Train noise currently experienced within the City results from the locomotive engines and warning horns associated with rail operations. These daily operations tend to produce high short-term noise levels that can be a source of annoyance to nearby sensitive uses. Depending on the number of daily movements, train operations also have the potential to generate noise levels that exceed 65 dBA CNEL along the rail corridors. GOAL 3.0: Minimize train noise in residential areas and near noise-sensitive land uses. Policy 3.1: Encourage noise-compatible land uses and incorporate noise-reducing design features within transit oriented, mixed-use development near rail corridors. NOISE ORANGE GENERAL PLAN N-5 Aircraft Noise Although no airports or airfields are located in Orange, noise generated by aircraft overflights can be noticeable throughout the City. Aircraft operations associated with John Wayne Airport, Long Beach Airport, and even Los Alamitos Army Airfield use the airspace above the City in arrival and departure operations. The general noise environment in the City also includes helicopter noise from private, police, emergency medical, and news/traffic monitoring helicopters. GOAL 4.0: Minimize aircraft related noise in residential areas and near noise-sensitive land uses. Policy 4.1: Continue to provide input to the Orange County Airport Land Use Commission as appropriate to minimize airport noise. Policy 4.2: Continue to work with regional, state, and federal agencies, including officials at John Wayne Airport and Long Beach Airport, to implement noise-reducing measures and to monitor and reduce noise associated with aircraft. Policy 4.3: Continue to coordinate with the Federal Aviation Administration, Caltrans Division of Aeronautics, and the Orange County Airport Land Use Commission regarding the siting and operation of heliports and helistops in order to minimize excessive helicopter noise. Mixed-use Development Mixed-use development projects often include both residential uses located above or in close proximity to commercial uses and stand-alone multi-family residential uses, especially in areas served by rail and bus transit, along major roadways and the railroad corridor. Noise generated by commercial uses can include mechanical equipment operations, maintenance activities, public address systems, vehicles, entertainment, parking lots, loading operations, and trash collection, as well as pedestrian and business patron noise. A unique challenge presented by mixed-use development is that on one hand, such uses desire locations along busy street corridors and within activity centers, and on the other hand, state-mandated interior noise requirements for residential uses must be met within the residential portions of such use. GOAL 5.0: Minimize commercial activity noise in residential portions of mixed-use areas where residential units are located above commercial uses or within the same development. Policy 5.1: Encourage the design and construction of mixed-use structures to minimize commercial noise within the residential components of the development. Policy 5.2: Encourage new mixed-use development to locate the residential component of the development away from noise-generating sources such as mechanical equipment, entertainment facilities, gathering places, loading bays, parking lots, driveways, and trash enclosures. Policy 5.3: Encourage residential developments within mixed-use developments and located adjacent to commercial or retail and entertainment related uses to notify potential residents that they may be affected by noise from these uses. NOISE ORANGE GENERAL PLAN N-6 Industrial Noise Industrial land uses have the potential to generate noise that can be considered intrusive to sensitive land uses. Depending on the type of industrial operation, noise sources could involve mechanical equipment, loading and unloading of vehicles and trucks, as well as amplified or unamplified communications. The level and intrusiveness of the noise generated also vary depending on the size of the facility, type of business, hours of operation , and location relative to sensitive land uses. GOAL 6.0: Minimize industrial activity noise in residential areas and near noise- sensitive land uses. Policy 6.1: Encourage the design and construction of industrial uses to minimize excessive noise through project design features that include noise control. Policy 6.2: Encourage industrial uses to locate vehicular traffic and operations away from abutting residential zones as much as possible. Construction, Maintenance, and Nuisance Noise Construction operations and maintenance vehicles such as refuse trucks and parking lot sweepers generate noise throughout the City. Although these types of noise sources tend to be short term, temporary, and limited, they can be a source of annoyance, especially during the late night or early morning hours. GOAL 7.0: Minimize construction, maintenance vehicle, and nuisance noise in residential areas and near noise-sensitive land uses. Policy 7.1: Schedule City maintenance and construction projects so that they generate noise during less sensitive hours. Policy 7.2: Require developers and contractors to employ noise minimizing techniques during construction and maintenance operations. Policy 7.3: Limit the hours of construction and maintenance operations located adjacent to noise-sensitive land uses. Policy 7.4: Encourage limitations on the hours of operations and deliveries for commercial, mixed-use, and industrial uses abutting residential zones. NOISE PLAN Noise is most often defined as unwanted sound. Potential noise problem areas are considered to be those areas where ambient noise levels exceed established noise standards, and areas where sensitive land uses are exposed to excessive ambient noise levels. Excessive noise is viewed as a disturbance, especially to residential communities and other noise- sensitive uses. Noise sources in Orange fall into two categories: transportation oriented and non-transportation oriented. Examples of transportation oriented noise include noise generated by vehicles, airplanes, and rail cars operating within the City. Examples of non- transportation noise include noise generated from mechanical or industrial processes and lawn equipment. NOISE ORANGE GENERAL PLAN N-7 The most prevalent noise source within the City is vehicular traffic on highways, freeways, toll roads, and arterials—specifically, the I-5, SR-55, SR-57, SR-91 and SR-22 freeways that surround and pass through the City; the SR-241 toll road that crosses the eastern portion of the City; and the many arterial roadways that traverse almost all areas of the community. Other noise sources include passenger and freight rail operations, industrial facilities, loading docks and mechanical equipment at retail centers. Periodic sources of noise include train traffic (Amtrak, Metrolink, and freight trains); aircraft overflights into and out of John Wayne Airport, Long Beach Airport, and Los Alamitos Army Air Station; helicopter traffic along the Main Street and Katella Avenue corridors and over residential neighborhoods; sporting and exhibition events and fireworks shows in the City of Anaheim; and operation of trucks and machinery throughout Orange’s industrial areas. Measuring Noise Although sound can be easily measured, the perception of noise levels is subjective and the physical response to sound complicates the analysis of its effects on people. People judge the relative magnitude of sound sensation in subjective terms such as noisiness or loudness. Sound pressure magnitude is measured and quantified using a logarithmic ratio of pressures, the scale of which gives the level of sound in decibels (dB). Table N-1 presents the subjective effect of changes in sound pressure levels. Table N-1 Changes in Sound Pressure Levels, dB dB Change Change in Apparent Loudness +/- 3 dB Threshold of human perceptibility +/- 5 dB Clearly noticeable change in noise level +/-10 dB Half or twice as loud +/-20 dB Much quieter or louder Source: Engineering Noise Control, Bies and Hansen (1988). To account for the pitch of sounds and an average human ear’s response to such sounds, a unit of measure called an A-weighted sound pressure level (dBA) is used. To provide some perspective on the relative loudness of various types of noise, Table N-2 lists common sources of noise and their approximate noise levels. Many metrics have been developed to account for the way humans perceive sound. The most common of these descriptors are the average “equivalent” noise level (Leq), the Day Night noise level (Ldn), and the Community Noise Equivalent Level (CNEL). Leq represents a measure of the average noise level at a given location over a specified period of time. Ldn and CNEL are based on a 24-hour Leq which applies offsets to evening and nighttime noise levels to account for the increased sensitivity of people to noise occurring at night. The Ldn is a 24-hour average sound level (similar to a 24-hour Leq) in which a 10 dB penalty is added to any sound occurring between the hours of 10:00 p.m. and 7:00 a.m. CNEL is similar to Ldn, except that a five dB penalty is also added for noise occurring during evening hours from NOISE ORANGE GENERAL PLAN N-8 7:00 p.m. to 10:00 p.m. Therefore, both the Ldn and CNEL noise metrics provide 24-hour averages of noise level exposure at a particular location, with temporal adjustments that reflect the increased sensitivity to noise during the evening and nighttime hours1. CNEL is the noise level descriptor, consistent with state guidelines, applied by the City throughout this Noise Element to describe the current and future noise environment affected by transportation-generated noise.

Noise Standards and Land Use Compatibility Orange has developed its own land use compatibility standards, based on recommended parameters from the California Governor’s Office of Planning and Research, that rate compatibility in terms of normally acceptable, conditionally acceptable, normally unacceptable, and clearly unacceptable. Using these land use compatibility guidelines, the City has established interior and exterior noise standards. 1 In practical implementation CNEL and Ldn could be used interchangeably for traffic generated noise as the difference between these two descriptors for urban / suburban noise levels is less than one dB. NOISE ORANGE GENERAL PLAN N-9 The City’s compatibility standards provide only for normally acceptable conditions, based on state recommendations and City land use designations. The City’s Land Use Compatibility standards are presented in Table N-3. These standards, which use the CNEL noise descriptor, are intended to be applicable for land use designations exposed to noise levels generated by transportation related sources. Land use compatibility noise exposure limits are generally established as 65 dBA CNEL for a majority of land use designations throughout the City. Higher exterior noise levels are permitted for multiple-family housing and housing in mixed- use contexts than for single-family houses. This is because multiple-family complexes are generally located in transitional areas between single-family and commercial districts or in proximity to major arterials served by transit, and a more integrated mix of residential and commercial activity (accompanied by higher noise levels) is often desired in mixed-use areas close to transit routes. These standards establish maximum interior noise levels for new residential development, requiring that sufficient insulation be provided to reduce interior ambient noise levels to 45 dBA CNEL. The City’s land use compatibility standards are based first on the General Plan land use designation of the property, and secondly on the use of the property. For example, within the Urban Mixed-use designation, a multiple-family use exposed to transportation related noise would have an exterior noise standard of 65 dBA CNEL, and an interior noise standard of 45 dBA CNEL. Noise standards for multiple-family and mixed-use land use designations shown in Table N-3 are higher than those for rural or single-family residential areas, reflecting the gradually changing character of Orange and a more urban environment planned for certain areas of the City. The standards shown in Table N-3 are purposefully general in nature, and not every specific land use which could be accommodated within each General Plan designation is identified. Application of the standards will vary on a case-by-case basis according to location, development type, and associated noise sources. When non-transportation (stationary) noise is the primary noise source, and to ensure that noise producers do not adversely affect noise-sensitive land uses, the City applies a second set of standards when planning and making development decisions. These hourly and maximum performance standards (expressed in Leq) for non-transportation or stationary noise sources are designed to protect noise sensitive land uses adjacent to stationary sources from excessive noise. Table N-4 summarizes City stationary source noise standards for various land use types. These standards represent the acceptable exterior noise levels at the sensitive receptor. For City analysis of noise impacts and determining appropriate mitigation under the California Environmental Quality Act (CEQA), in addition to the maximum allowable noise level standards outlined in Tables N-3 and N-4, an increase in ambient noise levels is assumed to be a significant noise impact if a project causes ambient noise levels to exceed the following:  Where the existing ambient noise level is less than 65 dBA, a project related permanent increase in ambient noise levels of 5 dBA CNEL or greater.  Where the existing ambient noise level is greater than 65 dBA, a project related permanent increase in ambient noise levels of 3 dBA CNEL or greater.

However, these noise level standards do not apply to residential units established in conjunction with industrial or commercial uses (e.g., caretaker dwellings). (2) Each of the noise levels specified above should be lowered by five dB for simple tone noises, noises consisting primarily of speech or music, or for recurring impulsive noises. Such noises are generally considered by residents to be particularly annoying and are a primary source of noise complaints. These noise level standards do not apply to residential units established in conjunction with industrial or commercial uses (e.g. caretaker dwellings). (3) No standards have been included for interior noise levels. Standard construction practices that comply with the exterior noise levels identified in this table generally result in acceptable interior noise levels. (4) The City may impose noise level standards which are more or less restrictive than those specified above based upon determination of existing low or high ambient noise levels. If the existing ambient noise level exceeds the standards listed in Table N-4, then the noise level standards shall be increased at 3 dB increments to encompass the ambient environment. Noise level standards incorporati ng adjustments for existing ambient noise levels shall not exceed a maximum of 70 dB Leq. Noise Contours and Impact Areas The community noise environment can be described using contours derived from monitoring major sources of noise. Noise contours define areas of equal noise exposure. Future noise contours have been estimated using information about both current and projected future land use development and traffic volumes. The contours assist in setting policies for distribution of land uses and establishing development standards. A study of baseline noise sources and levels was completed by Alliance Acoustical Consultants in November 2004. Noise level measurements were collected during a typical weekday at 28 locations throughout Orange. Criteria for site selection included geographical distribution, land uses suspected of noisy activities, proximity to transportation facilities, and noise-sensitive land uses. The primary purpose of noise monitoring was to establish a noise profile for the planning area that could be used to estimate levels of current and future noise. Measurements represent motor vehicle noise emanating from freeways, the local roadway network, and industrial land uses. Typical noise sources measured during the short-term survey included vehicular traffic, aircraft, trains, emergency sirens, industry, mechanical equipment, sporting events, firework shows, children playing, motorcycles, car alarms, and car audio systems. Of all these sources, traffic noise was determined to be the predominant noise source. Figure N-1 identifies noise contours for baseline year 2004. Major arterials and the railroad and freeway network represent the major sources of noise. A number of areas are exposed to traffic noise from arterials in excess of 65 dBA CNEL, including areas near State College Boulevard/The City Drive, Chapman Avenue, La Veta Avenue, Batavia Street, Glassell Street, Tustin Street, Katella Avenue, and Jamboree Road. NOISE ORANGE GENERAL PLAN N-12 The Land Use Element indicates that the planning area will accommodate additional future growth, accompanied by an increase in citywide traffic volumes. Traffic volume increases represent the major anticipated measurable new noise sources in the community over the long term. Potential future ambient noise levels can be estimated by modeling. Figure N-2 displays projected year 2030 noise contours based upon future traffic levels. Figure N-2 indicates that noise levels may be expected to rise in areas where roadways will experience the greatest increase in traffic volumes over time. Specifically, these areas include Tustin Street, State College Boulevard/The City Drive, Chapman Avenue, Jamboree Road, Santiago Canyon Road, Glassell Street, Main Street, I-5, SR-57, SR-22, SR-55, SR-241, SR-261, the Burlington Northern/Santa Fe Railroad, and throughout the City’s industrial area, Identification of Noise Problem Areas Potential noise problem areas are considered to be those areas where ambient noise levels exceed established noise standards and areas where sensitive land uses are exposed to ambient noise levels in excess of standards identified in Tables N-3 and N-4. For the most part, these problem areas lie along freeways, toll roads, and arterial and secondary roadways where noise barriers have not been installed. Beneath the landing pattern for aircraft approaching John Wayne Airport in Santa Ana, Long Beach Airport, and Los Alamitos Army Air Station, some residents in the area find the aircraft noise disturbing. The aircraft noise may be considered an intermittent, recurring noise problem. Helicopter noise from private, police, emergency medical, and news and traffic monitoring helicopters also contributes to the general noise environment in the City, particularly approaching University of California Irvine (UCI) Medical Center and Children’s Hospital of Orange County (CHOC). An additional noise problem cited by residents citywide is noise associated with the operation of hand-held, motorized leaf blowers. Gasoline powered blowers, which are generally used to clear debris from driveways, sidewalks, and landscaped areas generate noise levels in the range of 60 to 85 dBA Leq (measured 50 feet from the source). This noise level may exceed the standard established for stationary noise sources during both daytime and nighttime hours. Noise Control Techniques The most efficient and effective means of controlling noise is to reduce noise at the source. However, regarding noise generated from transportation systems, the City has no direct control over noise produced by trucks, cars, and trains, because state and federal noise regulations preempt local laws. Given that the City cannot control transportation noise at the source, City noise programs and standards focus on reducing transportation noise along freeways, arterial roadways, and rail corridors, through noise reduction methods that interrupt the path of the noise or directly shield the receiver. The emphasis of such noise reduction methods should be placed on site planning and design. Such reduction measures may include building orientation, spatial buffers, landscaping, and noise barriers. The use of noise barriers, such as sound walls, should be considered as a means of achieving the noise Note: Large format map available at the Community Development Department N-13 Figure N-1. 2004 Noise Contours NOISE ORANGE GENERAL PLAN N-14 (This Page Left Intentionally Blank) Note: Large format map available at the Community Development Depar tment N-15 Figure N-2. 2030 Noise Contours NOISE ORANGE GENERAL PLAN N-16 (This Page Left Intentionally Blank) NOISE ORANGE GENERAL PLAN N-17 standards only after all other practical design-related noise reduction measures have been integrated into the project. Sound walls may not be desirable in some cases, such as intersections in commerci al areas where visibility and access are important. Additionally, effective acoustical design features in new development can provide additional interior noise reduction. Regarding stationary and non-transportation generated noise, noise levels are to be addressed at the source as a primary focus. For mixed-use development in particular, acoustical design should be applied that isolates residential portions of mixed-use development from both commercial portions and external noise sources. When it is not feasible to address stationary noise at the source, the aforementioned noise reduction methods will be employed to reduce noise exposure to the levels presented in Table N-5. Table N-5 Sample Interior Noise Control Measures Noise Exposure Level Exterior to Interior Noise Level Reduction (NLR) Required to Achieve 45 dBA CNEL Noise Control Measures and Façade Upgrades > ≤60 dBA CNEL 15 dBA Normal construction practices consistent with the Uniform Building Code are typically sufficient. 60 dBA to 65 dBA CNEL 20 dBA Normal construction practices consistent with the Uniform Building Code are sufficient with the addition of the following specifications:  Air conditioning or mechanical ventilation systems are installed so that windows and doors may remain closed.  Windows and sliding glass doors are mounted in low air infiltration rated frames (0.5 cfm or less).  Exterior doors are solid core with perimeter weather-stripping and threshold seals. 65 dBA to 70 dBA CNEL 25 dBA Normal construction practices consistent with the Uniform Building Code are sufficient with the addition of the following specifications:  Air conditioning or mechanical ventilation systems are installed so that windows and doors may remain closed.  Windows and sliding glass doors are mounted in low air infiltration rated frames (0.5 cfm or less).  Exterior doors are solid core with perimeter weather-stripping and threshold seals.  Glass in both windows and exterior doors should have a Sound Transmission Classification (STC) rating of at least 30.  Roof or attic vents facing the noise source of concern should be boxed, or provided with baffling. Notes: (1) The information listed in this table is sample guidance for interior noise control recommendations and is not intended for application to individual development projects, renovations, or retrofits. Noise-sensitive land uses located in areas with noise level exposures exceeding 60 dBA CNEL should have a detailed acoustical analysis performed on a case by case basis. The most common and feasible method to control exterior-to-interior noise levels is achieved through improvements to the building structure and use of wall/façade treatments that reduce noise levels. Buildings constructed consistent with the Uniform Building Code (UBC) typically provide approximately 15 dBA of exterior-to-interior noise level reduction (NLR) with NOISE ORANGE GENERAL PLAN N-18 windows open, and 25 dBA of NLR with windows closed. Therefore, special consideration must be given to reducing interior noise levels to the required 45 dBA CNEL at noise-sensitive land uses exposed to noise levels in excess of 60 dBA. The NLR of a wall element or building façade can be calculated by first assuming a generalized A-weighted noise frequency spectrum for roadway traffic noise. Then, the composite transmission loss of the various wall materials and the wall’s structural design is considered in determining the resulting noise level in the receiving room. After correcting for room absorption, the overall noise level in the room is calculated. The ability to perform these calculations requires detailed floor plans and façade construction details. Calculation of required NLR and resultant interior noise levels should be conducted by a qualified acoustical consultant. Table N-5 provides an example of varying levels of building façade improvements that may be required to achieve compliance with the interior noise level standard of 45 dBA CNEL for land uses exposed to three different noise levels: 60 dBA CNEL, 65 dBA CNEL, and 70 dBA CNEL. City Noise Control Ordinance The primary tool used to implement noise policy will be the City’s noise control ordinance (Title 8 Health and Safety, Chapter 8.24, Orange Municipal Code). The ordinance gives the City authority to regulate noise at its source and thereby protect noise-sensitive land uses. It also establishes exterior and interior noise standards for all residential properties. The ordinance specifies permitted days and times for construction, repair, remodeling, or grading of real property, and exemptions to the ordinance. The City will continue to apply provisions of the noise control ordinance, and will modify the noise ordinance as needed to respond to policy direction within this Element, including the noise standards specified in Table N-4, and policies addressing noise in mixed-use land use districts. State Noise Standards The City will continue to enforce state laws which set forth requirements for the insulation of residential dwelling units from excessive and potentially harmful noise. Title 25, Section 1092 of the California Administrative Code establishes exterior and interior noise standards for multi-family residential development. Units established in areas where ambient noise levels exceed 65 dBA CNEL must incorporate noise reduction features into project design and construction. To reduce exterior noise levels, open space and other outdoor private areas should be shielded from the primary noise source (e.g., a freeway or railroad track). Insulation must be provided to reduce interior ambient noise levels to 45 dBA CNEL or lower, pursuant to Title 24 requirements. The City will continue to enforce these regulations. Particular challenges arise in the application of standards to mixed-use areas. Residential portions of mixed-use projects must meet the 45 dBA CNEL Title 24 interior noise requirements while located on busy commercial corridors. This obligation can be met by incorporating design features that insulate residential uses from commercial portions of the project. NOISE ORANGE GENERAL PLAN N-19 Sound Walls Along Toll Roads, Arterials, and Secondary Roadways The City will encourage Caltrans and the TCA to abide by Section 215.5 of the State Streets and Highway Code, which establishes a priority system for constructing noise barriers in the form of sound walls along freeways, to minimize exposure of residential or other noise- sensitive land uses to excessive freeway noise. Furthermore, all new residential development proposed adjacent to toll roads, arterials, and secondary roadways will be required to buffer itself by providing sound walls or a combination of berms and walls designed to achieve the noise and land use compatibility standards indicated in Table N-3 within common open spaces. In the event that sound walls are used, the analysis should include evaluation of multiple reflections between parallel noise barriers (e.g., large structures, noise barriers on each side of the highway) which could reduce the acoustical performance of individual barriers or result in unintended impacts to other parts of the community. Land Use Policy and Design of Residential Projects To mitigate non-transportation-related noise, the City will require site plan adjustments, higher insulation performance, spatial buffers, and other mitigation measures to absorb and block sound as needed. Design features incorporated into residential projects can be used to shield residents from excessive noise. For example, bedrooms, balconies and open space areas can be located away from streets and focused toward the interior of a project. The City will develop guidelines to assist developers to design structures that respond to noise concerns. Acoustical Studies Under certain conditions, the City may require acoustical studies to be prepared as part of the development review process to ensure adequate analysis of proposed development projects. Acoustical studies will be required for all discretionary projects where any of the following apply:  The project includes a noise-sensitive land use that is located within the existing or future 65 dBA CNEL contour for transportation noise sources.  The project will cause future traffic volumes to increase by 25 percent or more on any roadway that fronts a sensitive land use.  The project will expose a noise-sensitive land use to a stationary noise source or vibration source exceeding the standards outlined in Table N-4. Such stationary sources may include mechanical equipment operations, entertainment venues, and industrial facilities.  The project includes a noise-sensitive land use in the vicinity of existing or proposed commercial and industrial areas.  The project is a mixed-use development that includes a residential component. The focus of this type of acoustical study is to determine likely interior and exterior noise levels and to recommend appropriate design features to reduce noise. NOISE ORANGE GENERAL PLAN N-20 An acoustical analysis prepared in accordance with this Noise Element shall:  be the financial responsibility of the applicant seeking City approval of a project;  be prepared by a qualified person experienced in the fields of environmental noise assessment and architectural acoustics;  include representative noise level measurements with sufficient sampling periods and locations to adequately describe local conditions and predominant noise sources;  estimate existing and projected cumulative noise in terms of CNEL or Leq, and compare those noise levels to the adopted standards and policies of the Noise Element;  recommend appropriate mitigation to achieve compliance with the adopted policies and standards of the Noise Element. Where the noise source in question consists of intermittent single events, the report must address the effects of maximum noise levels in sleeping rooms in terms of possible sleep disturbance; and  estimate noise exposure after the prescribed mitigation measures have been implemented. Truck Routes Truck traffic generates noise that can disturb people in residential and other noise-sensitive land uses. Heavy trucks will not be permitted to drive through residential neighborhoods. Truck routes in Orange are located mostly in the general industrial area in the western part of the City, as well as on the higher capacity roadways that traverse the planning area. Truck routes are identified for such purposes as noise reduction, safety, roadway maintenance, and traffic operations. The Orange Municipal Code identifies trucks as motor vehicles designed, used, or maintained primarily for the transportation of property and having an unladen weight of six thousand pounds or more. Air Traffic Noise To lessen the impacts of noise associated with air traffic into and out of John Wayne Airport, Long Beach Airport, and Los Alamitos Army Air Station, the City will participate in regional efforts to require airlines to use quieter aircraft. Also, the City will work with airport officials and surrounding jurisdictions to restore instrument approach patterns (as opposed to visual approach) at John Wayne Airport. Finally, the City will continue to register noise complaints with the airport’s Noise Abatement Office to ensure airport officials are made aware of any noise problems. A limited number of heliports and helistops are located throughout the City, with the most active locations being UCI Medical Center and Childrens’ Hospital of Orange County. Helicopter operations at these facilities are regulated by the Federal Aviation Administration, Caltrans Division of Aeronautics, and the Orange County Airport Land Use Commission. The City will work with these parties to ensure compliance with all state and federal laws pertaining to helicopter operations. NOISE ORANGE GENERAL PLAN N-21 Rail Traffic Noise The City has established a “quiet zone” along portions of the Burlington Northern/Santa Fe Railroad corridor. Federal Railroad Administration regulations allow cities to delineate zones where trains are not allowed to blow warning horns. Without a formally established “quiet zone”, trains approaching all railroad crossings that intersect public streets are required to blow a warning horn at the intersection to warn motorists and pedestrians. “Quiet zones” may reduce noise impacts at these crossings, and will continue to be supported so long as they do not increase traffic and pedestrian hazards. NOISE IMPLEMENTATION The goals, policies, and plans identified in this Element are implemented through a variety of City plans, ordinances, development requirements, capital improvements, and ongoing collaboration with regional agencies and neighboring jurisdictions. Specific implementation measures for this Element are contained in the General Plan Appendix. 9/13/22, 8:37 AM Chapter 8.24 NOISE CONTROL https://library.qcode.us/lib/orange_ca/pub/municipal_code/item/title_8-chapter_8_24?view=all 1/7 Orange, California Municipal Code Title 8 HEALTH AND SAFETY Chapter 8.24 NOISE CONTROL Note 8.24.010 Policy. 8.24.020 Definitions. 8.24.030 Noise Level Measurement Criteria. 8.24.040 Exterior Standards. 8.24.050 Exemptions from Chapter Provisions. 8.24.060 Special Provisions for Schools, Hospitals and Churches. 8.24.070 Measurement of Noise Levels. 8.24.080 Enforcement Authority. 8.24.090 Violation—Public Nuisance. 8.24.100 Alternative Noise Prohibition. 8.24.110 Violation—Misdemeanor.

Katella Avenue In-Fill Residential Project (TTM 19253) Vehicle Miles Traveled (VMT) Analysis, City of Orange, CA Dear Mr. Carlson: Introduction RK ENGINEERING GROUP, INC. (RK) is pleased to provide this Vehicle Miles Traveled (VMT) Analysis for the proposed 901 E. Katella Avenue In-Fill Residential Project (TTM 19253). The purpose of this study is to utilize the City of Orange Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment, dated July 2020, which establishes uniform analysis methodology and thresholds of significance for determining LOS as well as VMT impacts under the California Environmental Quality Act (CEQA), to determine if the project will require a detailed VMT analysis. Project Description The project site is located at 901 E. Katella Avenue in the City of Orange. The project site is currently developed with a vacant AT&T call center. The proposed project consists of razing the existing vacant AT&T call center and constructing fifty-two (52) paired and detached townhomes. The project proposes 108 covered spaces and 11 uncovered spaces for a total of 119 parking spaces. The site has the following Assessor’s Parcel Number (APN): 375-461-41. The project site’s current Land Use is General Commercial and is currently zoned as Commercial Professional (C-P); the project site’s proposed land use is Medium Density Residential and is proposed to be zoned as Multiple-Family Residential (R-3). CARLSON STRATEGIC LAND SOLUTIONS RK17692 Page 2 RK17692.doc JN: 2827-2022-07 Access to the project is proposed via one (1) full-access unsignalized driveway located along N. Cambridge Street and via one (1) right-in/right-out only unsignalized driveway located along E. Katella Avenue. Exhibit A shows the location map of the proposed project. Exhibit B shows the proposed site plan. Vehicle Miles Traveled (VMT) Screening Analysis The City of Orange Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment, dated July 2020, provides recommendations in the form of thresholds of significance and methodology for identifying VMT related impacts. The proposed project is subject to a VMT analysis and will adhere to the recommendatio ns and practices described in the City’s guidelines. However, as specified in the City’s VMT guidelines, there are three steps of screening that can be applied to effectively screen projects from project-level of assessment. These are summarized below: • Step 1: Transit Priority Area (TPA) Screening • Step 2: Low VMT Area Screening • Step 3: Project Type Screening The North Orange County Collaborative VMT Traffic Study Screening Tool (NOCC+), a spreadsheet tool developed for the use of North County Cities (i.e. Fullerton, La Habra, Brea, Buena Park, Orange, Placentia, and Yorba Linda), was utilized to identify if the proposed project screens out from project-generated VMT impacts. The NOCC+ worksheet is provided in Appendix A. As shown in Appendix A, the proposed project does not meet the screening criteria for Step 1: Transit Priority Area (TPA) Screening, Step 2: Low VMT Area Screening, or Step 3: Project Type Screening, based on the Socioeconomic Data (SED) from OCTAM5.0 for the project’s TAZ (i.e. parcel No. 375-461-41; OCTAM TAZ No. 453). CEQA VMT Impact Thresholds Per the City of Orange VMT Guidelines, a project would result in a significant project - generated VMT impact if either of the following conditions are satisfied. 1. The baseline project-generated VMT per service population exceeds the City of Orange General Plan Buildout VMT per service population, or CARLSON STRATEGIC LAND SOLUTIONS RK17692 Page 3 RK17692.doc JN: 2827-2022-07 2. The cumulative project-generated VMT per service population exceeds the City of Orange General Plan Buildout VMT per service population. As stated in the City of Orange VMT Guidelines, the NOCC+ tool provides an estimate of the baseline plus project conditions and can be presented in lieu of results from a full model run. As such, this analysis utilizes the NOCC+ tool to determine if the project would result in a significant project-generated VMT impact, which is provided in Appendix A. Table 1 summarizes the results of the NOCC+ project VMT thresholds comparison. Table 1 NOCC+ Project VMT Threshold Comparisons Analysis Scenario(s) VMT per Service Population (OCTAM TAZ No. 453) City of Orange General Plan Build Out Baseline VMT per Service Population Threshold 31.3 Project VMT per Service Population 15.4 As shown in Table 1, the project-generated VMT per service population (i.e. 15.4 VMT per service population) does not exceed the City of Orange General Plan Build Out Baseline VMT per service population threshold (i.e. 31.3 VMT per service population). Thus, the project’s impact on VMT can be considered less than significant and no further VMT analysis is required. It should be noted, as stated within the City of Orange VMT Guidelines, if the baseline scenario results in a less-than-significant impact, then additional cumulative scenario analysis may not be required. Conclusion RK Engineering Group, Inc. has completed this Vehicle Miles Traveled (VMT) Analysis for the proposed 901 E. Katella Avenue In-Fill Residential Project (TTM 19253). The project-generated VMT per service population (i.e. 15.4 VMT per service population) does not exceed the City of Orange General Plan Build Out Baseline VMT per service population threshold (i.e. 31.3 VMT per service population). Thus, the project’s impact on VMT can be considered less than significant and no further VMT analysis is required.

Katella Avenue In-Fill Residential Project (TTM 19253) Trip Generation Analysis, City of Orange, CA Dear Mr. Carlson: Introduction RK ENGINEERING GROUP, INC. (RK) is pleased to provide this Trip Generation Analysis for the proposed 901 E. Katella Avenue In-Fill Residential Project (TTM 19253). The purpose of this study is to utilize the City of Orange Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment, dated July 2020, which establishes uniform analysis methodology and thresholds of significance for determining LOS as well as VMT impacts under the California Environmental Quality Act (CEQA), to determine if the project will require a detailed level of service (LOS) analysis. Project Description The project site is located at 901 E. Katella Avenue in the City of Orange. The project site is currently developed with a vacant AT&T call center. The proposed project consists of razing the existing vacant AT&T call center and constructing fifty-two (52) paired and detached townhomes. The project proposes 108 covered spaces and 11 uncovered spaces for a total of 119 parking spaces. The site has the following Assessor’s Parcel Number (APN): 375-461-41. The project site’s current Land Use is General Commercial and is currently zoned as Commercial Professional (C-P); the project site’s proposed land use is Medium Density Residential and is proposed to be zoned as Multiple-Family Residential (R-3). CARLSON STRATEGIC LAND SOLUTIONS RK17680 Page 2 RK17680.doc JN: 2827-2022-07 Access to the project is proposed via one (1) full-access unsignalized driveway located along N. Cambridge Street and via one (1) right-in/right-out only unsignalized driveway located along E. Katella Avenue. Exhibit A shows the location map of the proposed project. Exhibit B shows the proposed site plan. Project Trip Generation Trip generation represents the amount of traffic that is attracted and produced by a development. Trip generation is typically estimated based on the trip generation rates from the latest Institute of Transportation Engineers (ITE) Trip Generation Manual. The latest and most recent version (11th Edition, 2021) of the ITE Manual has been utilized for this trip generation analysis. This publication provides a comprehensive evaluation of trip generation rates for a variety of land uses. The proposed project consists of fifty-two (52) paired and detached townhomes. As such, ITE Land Use 215: Attached Single-Family Attached Housing rates are the most appropriate for this land use. Table 1 shows the ITE trip generation rates (11th Edition) utilized for the trip generation analysis of the proposed project land use.

The Project site is located at the northeast corner of Katella Avenue and Cambridge Street, and addressed at 901 Katella Avenue. Pursuant to the City of Orange requirements, a stopping sight distance analysis has been conducted at the proposed Project driveway located along Cambridge Street. PROJECT LOCATION AND DESCRIPTION The Project site is located at the northeast corner of Katella Avenue and Cambridge Street, and addressed at 901 Katella Avenue in the City of Orange, California. The subject property is currently developed with a vacant office building and surface parking. Access to the site is now provided via a gated full access unsignalized driveway on Katella Avenue and a gated left-turn in/right-turn in/right-turn out access unsignalized driveway on Cambridge Street. Figure 1, located at the rear of this letter report, presents a vicinity map which illustrates the general location of the project and the surrounding street system. The proposed Project includes the construction of a 52-unit condominium/townhome residential community. Primary access to the Project site is proposed via a full access unsignalized driveway located along Cambridge Street, which would be constructed 44 feet south of the existing driveway. It is anticipated that the outbound movement would be controlled via a stop sign. All other movements would be uncontrolled. To facilitate the proposed full access at the Project’s primary access, striping Emilie Simard May 30, 2023 Page 2 N:\4500\2224577 - 901 Katella Avenue Residential, Orange\Report\4577 901 Katella Residential Sight Distance Evaluation Letter 5-30-2023.doc modifications would be required along Cambridge Street as a result of relocation the existing driveway to the south. These striping improvements, to allow for full access, would be subject to findings of this analysis and the review and approval of the City of Orange. Emergency vehicle only access is proposed to be provided via a driveway located on Katella Avenue along the site’s easterly property line. Figure 2 presents an existing aerial photograph of the Project site. Figure 3 presents the proposed Project site plan prepared by Bassenian/Lagoni Architects dated June 14, 2022. SITE ACCESS EVALUATION Sight Distance Analysis At intersections and/or project driveways, a substantially clear line of sight should be maintained between the driver of a vehicle waiting at the crossroad and the driver of an approaching vehicle. Adequate time must be provided for the waiting vehicle to either cross all lanes of through traffic, cross the near lanes and turn left, or turn right, without requiring through traffic to radically alter their speed. A sight distance evaluation has been performed for the proposed project driveway located along Cambridge Street. The Sight Distance Evaluation for the project driveway utilized the criteria and procedures set forth by the California Department of Transportation (Caltrans) in the State’s Highway Design Manual (HDM) for “Private Road Intersections” consistent with standard traffic engineering practice. Highway Design Manual (HDM) Sight Distance Criteria The Sight Distance Evaluation for the Project driveway to verify the adequacy of sight lines was also based on the criteria and procedures set forth by the California Department of Transportation (Caltrans) in the State’s Highway Design Manual (HDM) for “Private Road Intersections”. Stopping sight distance was utilized for the evaluation, although the Caltrans HDM, in Section 405.1(2)(c), page 400-27, indicates that for Private Road Intersections, “The minimum corner sight distance shall be equal to the stopping sight distance as given in Table 201.1...”. Stopping sight distance is measured from the driver’s eyes, which are assumed to be 3.5 feet above the pavement surface, to an object 0.5-foot high on the roadway. Emilie Simard May 30, 2023 Page 3 N:\4500\2224577 - 901 Katella Avenue Residential, Orange\Report\4577 901 Katella Residential Sight Distance Evaluation Letter 5-30-2023.doc Stopping sight distance is defined in the Caltrans HDM to be the distance required by the driver of a vehicle, traveling at a given speed, to bring the vehicle to a stop after an object ½ foot high on the road becomes visible. Stopping sight distance is measured from the driver’s eyes, which is assumed to be 3 ½ feet above the pavement surface, to an object ½ foot high on the road. The speed used in determining stopping sight distance is defined as the “critical speed” or 85th percentile speed which is the speed at which 85% of the vehicles are traveling at or less. The critical speed is the single most important factor in determining stopping sight distance. Table 201.1 in the HDM is used in determining stopping sight distance based on the critical speed of vehicles on the affected roadway. Speed count data was collected along Cambridge Street on July 12, 2022. This data identifies an 85th percentile speed of 35 miles per hour (mph). Appendix A presents the speed count data. Based on Table 201.1 of the Caltrans HDM and a speed of 35 mph on Cambridge Street, a stopping sight distance of 250 feet is required for both a left-turning and right-turning vehicle at the project driveway. Project Driveway Outbound Left-Turn Evaluation Figure 4 presents the results of the sight distance evaluation at the project driveway for left-turning vehicles based on the application of stopping sight distance. As shown, the sight lines are expected to be adequate per the HDM standards as long as obstructions within the sight triangles are minimized. Adequate sight lines give the motorist the ability to see gaps in traffic to help with egress from the site. As a result of the driveway relocation, striping modifications are required along Cambridge Street and will be constructed as a project design feature, subject to review and approval of the City. Project Driveway Outbound Right-Turn Evaluation Figure 5 presents the results of the sight distance evaluation at the project driveway for right-turning vehicles based on the application of stopping sight distance. As shown, the sight lines are expected to be adequate per the HDM standards as long as obstructions within the sight triangles are minimized. Adequate sight lines give the motorist the ability to see gaps in traffic to help with egress from the site. As a result of the driveway relocation, striping modifications are required along Cambridge Street and will be constructed as a project design feature, subject to review and approval of the City. Emilie Simard May 30, 2023 Page 4 N:\4500\2224577 - 901 Katella Avenue Residential, Orange\Report\4577 901 Katella Residential Sight Distance Evaluation Letter 5-30-2023.doc Project Driveway inbound Left-Turn Evaluation Figure 6 presents the results of the sight distance evaluation at the project driveway for southbound left-turning vehicles into the site based on the application of stopping sight distance. As shown, the sight lines are expected to be obstructed by vehicles queued in the southbound left-turn lane and/or southbound through lane at the intersection of Cambridge Street and Katella Avenue. As a result, the southbound left-turn movement is recommended to be restricted. Striping modifications would be needed as a result along with signage and will be constructed as a project design feature, subject to review and approval of the City. Conceptual Improvement Plan Based on the information identified above, it is recommended that the southbound left-turn movement along Cambridge Street be prohibited. Additionally, the striping adjacent to the bike line would require modifications due to the driveway relocation as well. As such, Figure 7 presents the conceptual striping along Cambridge Street to help facilitate ingress and egress to the Site. CONCLUSION Based on the above, the sight lines at the project driveway located along Cambridge Street are expected to be adequate per the HDM standards as long as obstructions within the sight triangles are minimized for the outbound (left-turn and right-turn) movements. Given that parking is not permitted along the Project frontage on Cambridge Street, the potential obstruction of vehicles parked along the curb is minimized. For the southbound left-turn inbound movement, there is a potential of sight lines to be obstructed due to the alignment of Cambridge and vehicular queues and hence adequate stopping sight distance is not provided. As a result, this movement is recommended to be prohibited. Striping modifications and appropriate signage shall be implemented by the Project to restrict the southbound left-turn movement along Cambridge Street. These striping improvements are subject to the review and approval of the City of Orange. * * * * * * * * * * Emilie Simard May 30, 2023 Page 5 N:\4500\2224577 - 901 Katella Avenue Residential, Orange\Report\4577 901 Katella Residential Sight Distance Evaluation Letter 5-30-2023.doc We appreciate the opportunity to be of service on this Project.

Chapman Avenue Orange, CA 92866 9830 Irvine Center Drive, Irvine, California 92618 Office: 949.916.3800 WWW.CVC-INC.NET To Whom it may concern: Per the requirements indicated by the City of Orange, Public Works Department, the existing sanitary and ultimate design sewer capacity data provided per the enclosed sewer model map has been analyzed to determine the potential impact as a result of the proposed 52 unit residential development located at E. 901 Katella Avenue, Orange. Using the ultimate design and existing capacity information indicated on the sewer model map, the “future” proposed depth of flow has been calculated to determine the capacity of the existing 15” public sewer main located within E. Katella Avenue, approximately 5’ south of the centerline at the anticipated connection point. Average daily flows were calculated for the existing and proposed site land uses utilizing the sewer generation flow rates per the Orange County Sanitation District (OCSD), Design and Construction for Sanitary Sewer dated November 2014. By applying the difference between the existing and proposed calculated flow rates and combining with the existing flow rate indicated on the sewer model map design, pipe capacity increased by approximately 0.0013 ft (0.0156 in) with a calculated d/D = 0.4382. The increased flow capacity within the existing 15” sewer main is insignificant, and well below the 50% depth to diameter ratio capacity, therefore we do not anticipate any capacity issues based on the point of connection pipe segment.

A=2.71 ac (2,262 gpd) * (2.71 ac) * (2.5) = 15,325 gpd/ac = 0.0237 cfs Medium Density Residential Area (Proposed Land Use) From the OCSD criteria for average daily flow, the coefficient of GPD per acre for medium density residential land use is 3,451 GPD with an applied 2.5 peaking factor. A=2.69 ac (3’ R/W dedication along Cambridge) (3,451 gpd) * (2.69 ac) * (2.5) = 23,208 gpd/ac = 0.0359 cfs Difference: 0.0359 cfs – 0.0237 cfs = 0.0122 cfs Therefore, the proposed “future” flow after connection will be approximately: 2.4097 cfs + 0.0122 cfs = 2.4219 cfs Therefore, the proposed “ultimate” design sewer main flow after connection will be 3.0456 cfs + 0.0122 cfs = 3.0578 cfs 9830 Irvine Center Drive, Irvine, California 92618 Office: 949.916.3800 WWW.CVC-INC.NET Proposed “Future” Conditions Project Data Project Title: INTR-013 Site Address: 901 E.
