NOW, THEREFORE, BE IT RESOLVED that the City Council adopts the update to the Historic Preservation Design Standards for Old Towne Orange, dated November 20, 2017, as amended by the Design Review Committee and Planning Commission, and as set forth in Exhibit A, based on the following findings: SECTION 1— FINDINGS General Plan Findings: 1. The project must be consistent with the goals and policies stated within the City's General Plan. The update to the Historic Preservation Design Standards for Old Towne Orange is consistent with the General Plan goals and policies of the Cultural Resources & Historic Preservation Element in that the update to the Design Standards directly incorporates the Secretary's Standards and related guidance from the National Park Service on the treatment of historic properties. As a result, projects that are in conformance with the Design Standards will also Resolution No. 11053 2 be in conformance with the Secretary's Standards. The update brings the Design Standards more closely into alignment with the Secretary's Standards and ensures the long -term preservation of historic resources by emphasizing the preservation and retention of historic materials and features. The Design Standards update is also consistent with the goals and policies of the Urban Design Element, because the update clarifies the standards for new construction related to historic buildings, including additions and infill construction, to ensure that the mass, scale, design, and materials of these projects are compatible with the character of the Historic Districts and in conformance with the Secretary's Standards. The update improves the existing Design Standards by clearly describing the expectations for high - quality rehabilitation of historic buildings and compatible new construction to ensure transparency for property owners and design professionals working in the Historic District. It continues the long - standing emphasis of the Design Standards on preservation of the character of Old Towne as a historic neighborhood, including the incorporation of appropriately scaled and detailed new construction. SECTION 2 — ENVIRONMENTAL REVIEW The update to the Design Standards is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) per State CEQA Guidelines 15308 (Class 8 - Actions by Regulatory Agencies for Protection of the Environment) and 15331 (Class 31 - Historical Resource Restoration/Rehabilitation). The update clarifies and improves the existing Historic Preservation Design Standards for Old Towne Orange, which were adopted by City Council in 1995 for the protection for the local and National Register- designated Old Towne historic districts. This update of existing procedures, policies, and standards is consistent with the City Council's prior action adopting the Design Standards in order to preserve designated historic resources. It assures the maintenance and protection of the environment through the preservation of historic resources and appropriate standards for new construction in the historic districts, as required by the Class 8 exemption. In addition, the update to the Design Standards is written such that projects found to be in conformance with the Design Standards will also be in conformance with the Secretary of the Interior's Standards for the Treatment of Historic Properties (Secretary's Standards). The update is consistent with and uses extensive guidance from the National Park Service on interpreting and implementing the Secretary's Standards, including the Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings. The updated Design Standards are in conformance with the Secretary's Standards and projects designed in conformance therewith will be categorically exempt from environmental review under the Class 31 exemption for Historical Resource Restoration/Rehabilitation. There is no environmental public review required for a Categorical Exemption. SECTION 3 — ACTION The update to the Historic Preservation Design Standards for Old Towne Orange, dated November 20, 2017, are hereby adopted as set forth in Exhibit A, attached hereto and incorporated herein.

Orange is a special place to live in part because of the historic buildings that help to create neighborhood character. Beginning in the 1970s, Orange's historic resources have been preserved through the joint efforts of community groups. Early preservation achievements included the Chapman College (now Chapman University) nomination of the Orange Union High School campus to the National Register of Historic Places (National Register) in 1975 and the Orange Community Historical Society's nomination of the Plaza to the National Register in 1978. In 1982, in response to community interest, the City initiated the first historic resources survey of pre -1940 buildings in Orange, with a focus on the Old Towne area. That same year, the Orange Community Historical Society and the City partnered on the National Register designation of the Plaza Historic District, consisting of the four commercial blocks around Plaza Park. By 1985, a second community organization was established to advocate for historic reservatiop nm Old Towne: the Old Towne Preservation Association (OTPA). An update of the historic resources survey was completed by the City in 1992, and the survey update was used to establish the local Old Towne Historic District, a nearly mile square area of historic residential, commercial, institutional and industrial buildings, centered on the historic downtown core. Working with community groups, the City developed and adopted the Historic Preservation Design Standards for Old Towne, or Old Towne Design Standards, in 1995 to provide property owners guidance on how to maintain and repair historic buildings and plan for new construction. In 1997, a more concentrated version of the local Old Towne Historic District was listed in the National Register through a nomination prepared by OTPA. The Orange Barrio Historical Society was also founded by local residents to celebrate and preserve the character of the Cypress Street Barrio, a neighborhood historically settled by Mexican and Mexican American families that developed around Cypress Street starting in the 1890s. The Old Towne Preservation Association, Orange Community Historical Society, and Orange Barrio Historical Society remain active participants in historic preservation in Orange. As demonstrated by the dedicated efforts of residents and community groups, Orange's historic buildings and neighborhoods convey a distinct sense of place. The purpose of the Historic Preservation Design Standards (HPDS) is to protect this unique character. The HPDS help property owners, design professionals and residents understand the features that make buildings and neighborhoods special and provide guidance on how best to preserve those features. The HPDS also guide the design of new construction so that it relates respectfully to historic buildings. The HPDS recognize that historic buildings and neighborhoods change over time. New buildings do not necessarily need to look old, but should closely relate to the mass, scale, form and setbacks of historic buildings. The review process established through the HPDS ensures that proposed new construction is compatible with existing historic features through range of flexible design guidelines. y the community- driven interest in historic preservation, ire are sound economic reasons why historic preservation makes sense. Historic preservation increases property values. Studies have consistently shown that properties in historic districts with robust design guidelines have higher property values than surrounding neighborhoods, even when compared with adjacent blocks that have similar lot and house sizes Historic preservation creates jobs. Rehabilitation of historic buildings requires skilled craftspeople who are familiar with local construction methods and materials. While much attention is given to jobs created by new construction, rehabilitation of historic buildings also creates many jobs in local construction trades and supports the local economy Historic preservation attracts visitors. Heritage tourism is an expanding industry, and preserving historic buildings enhances the City's tourism potential, which benefits small businesses and the local economy Historic preservation is sustainable development. Preservation means maintaining and re -using existing buildings, which is essentially recycling on a neighborhood scale. If an existing building is demolished, all of the energy that went into the extraction of raw materials, transportation, manufacturing, distribution and construction is lost. Demolition is ultimately a lost investment in the craftsmanship and materials of historic buildings, while rehabilitation re -uses and reinvests in these assets RELATED GUIDANCE Secretary's Standards The National Park Service has developed historic preservation standards, called the Secretary of the Interior's Standards for the Treatment of Historic Properties (Secretary's Standards) that apply to a wide variety of historic properties across the country. The Secretary's Standards are a series of concepts about maintaining, repairing, and replacing historic materials, as well as designing new additions or making alterations. The Secretary's Standards address four treatments for historic properties: preservation, rehabilitation, restoration, and reconstruction. Preservation is the act or process of applying measures necessary to sustain the existing form, integrity, and materials of a historic property. Work generally focuses on ongoing maintenance and repairs of historic materials and features rather than extensive replacement or new construction. WHY HISTORIC PRESERVATION? Rehabilitation is the act or process of making possible a compatible use for a property through repair, alterations, and additions while preserving those portions or features which convey its historical, cultural, or architectural values. Restoration is the act or process of accurately depicting the form, features, and character of a property as it appeared at particular period of time by means of the removal of features from other periods in its history and reconstruction of missing features from the restoration period. Reconstruction is the act or process of depicting, by means of new construction, the form, features, and detailing of a non - surviving site, landscape, building, structure, or object for the purpose of replicating its appearance at a specific period of time and in its historic location. The Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing Historic Buildings offer general design and technical recommendations to assist in applying the Standards to a specific property. Together with the Standards, they provide a framework and guidance for decision - making about changes to a historic property. The Secretary's Standards and Guidelines can be applied to historic properties of all types, materials, construction, sizes, and uses. They include both the exterior and the interior and extend to a property's landscape features, site, environment, as well as related new construction. Federal agencies use the Standards and Guidelines in carrying out their historic preservation responsibilities. State and local officials use them in reviewing both Federal and nonfederal rehabilitation proposals. In Orange, the Standards and Guidelines guide design review of projects in Old Towne and are used to supplement and support the Historic Preservation Design Standards. Projects in the Old Towne historic districts should be in conformance with both the Secretary's Standards and the Historic Preservation Design Standards. The HPDS are written to be consistent with the Secretary's Standards, so projects that are found to be in conformance with the HPDS generally are considered to be in conformance with the Secretary's Standards. Most projects will apply the Rehabilitation Standards, which acknowledge the need to alter or add to a historic building to meet continuing or new uses while retaining the building's historic character. The Rehabilitation Standards consist of ten principles: 1. A property will be used as it was historically or be given a new use that requires minimal change to its distinctive materials, features, spaces, and spatial relationships. 2. The historic character of a property will be retained and preserved. The removal of distinctive materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided. 3. Each property will be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or elements from other historic properties, will not be undertaken. 4. Changes to a property that have acquired historic significance in their own right will be retained and preserved. 5. Distinctive materials, features, finishes, and construction techniques or examples of craftsmanship that characterize a property will be preserved. 6. Deteriorated historic features will be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. Replacement of missing features will be substantiated by documentary and physical evidence. 7. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used. 8. Archeological resources will be protected and preserved in place. If such resources lust be disturbed, mitigation measures will be undertaken. 9. New additions, exterior alterations, or related new construction will not destroy historic materials, features, and spatial relationships that characterize the property. The new work will be differentiated from the old and will be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. 10. New additions and adjacent or related new construction will be undertaken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. i ne National Park Service has prepared guidance on how to interpret the Secretary's Standards. These publications include Preservation Briefs, Preservation Tech Notes, and Interpreting the Standards Bulletins available on the NPS website: www.nps. gov /tps /standards.htm. They provide valuable guidance to supplement the HPDS, and we encourage you to consult them while planning projects for your historic property. Appendix B provides a complete list of these publications. They are also referenced throughout the HPDS. Standards for Rehabilitation Basic Principles for Applying the HPDS The HPDS are based on the ten rehabilitation principles of the Secretary's Standards. Under the HPDS, there is hierarchy of recommendations for historic buildings, starting with the least invasive treatments and moving to those that require the most change. This sequence serves as a foundation for planning projects involving historic buildings and should direct property owners looking to maintain and repair the character - defining features of a historic building. Character - defining features are those visual and physical features that comprise the appearance of a historic resource. They may include the overall shape of a building, materials, craftsmanship, decorative details, interior spaces and features, as well as various aspects of the site and environment. Maintain character - defining features that are in good condition. Regular maintenance is critical to long -term preservation of historic buildings. 2. Repair character - defining features that are deteriorated to the original condition. In most cases, repair is better than replacement because it preserves the historic materials on the building. Replace only the character - defining features that cannot be repaired. Replacement should be in kind, matching the materials, details, and finish of the feature. 4. Reconstruct missing character - defining features. The reconstruction should be based on documentary or physical evidence on the building. 5. Design new features or additions to be compatible with the historic building and minimize the impact to character - defining features. The HPDS draw from this sequence to establish appropriate treatments for specific building types and features. California Historical Building Code The City of Orange has adopted use of the California Historical Building Code (California Code of Regulations, Title 24, Part 8) for historic Drooerties. ThP niirnnca of tkn California Historical Building Code (CHBC) is to provide solutions for the preservation of qualified historical properties, to promote sustainability, to provide access for persons with disabilities, to provide a cost - effective approach to preservation, and to provide for the reasonable safety of occupants or users. The CHBC allows the City to accept solutions that are reasonably equivalent to the regular building code when dealing with qualified historical properties. A qualified historical property is any building, site, object, place, location, district or collection of structures, and their associated sites, deemed of importance to the history, architecture, or culture of an area by an appropriate local, state or federal governmental jurisdiction. Historic buildings are qualified historical properties. The City's Chief Building Official determines the appropriate use of the CHBC. If you anticipate that your project will require use of the CHBC, please contact the Historic Preservation Planner early in the process. 5 DO THE HPDS APPLY TO MY PROJECT? The Historic Preservation Design Standards apply to properties located in established historic districts. Orange has three established historic districts: the National Register Plaza Historic District, the National Register Old Towne Orange Historic District, and the local Old Towne Orange Historic District. These three overlapping historic districts are collectively called the Old 00, Towne historic districts. Each historic district contains contributing and non - contributing structures which are identified in the National Register designation form and the City's Historic Resources Inventory Update adopted by City Council in 2010. A contributing structure is a structure that was constructed within the period of significance for the historic districts and retains design elements and materials from that period. A contributing structure must retain integrity, or the ability to convey its associations with events, people or designs from the past through its historic materials and forms. Contributing buildings are historically significant. Accessory structures that appear to have been constructed during the period of significance are considered to be contributing structures unless the property owner presents substantial evidence that the structure was not constructed during the period of significance or has lost integrity. A non - contributing structure either was constructed outside of the period of significance or has been altered so much that it no longer retains the design elements and materials that identify it as being from that period. Non- contributing buildings are not historically significant within the context of the historic district. Period of significance is the span of time during which the significant events or activities occurred. A period of significance can range from a single day to many tens or hundreds of years, depending on the reason why the property has historical significance. The periods of significance for the Old Towne historic districts are found on pages 12 -13. In some cases, properties that are identified as non - contributing to the Old Towne historic districts may be separately significant as individual historic resources. This might occur if the property is an important architectural style or associated with an important person or historical event, separate from the context of the historic districts. If you are proposing changes to a building that is more than 40 years old, please consult with Planning Division staff early to determine the review process that may be required under the California Environmental Quality Act (CEQA). The HPDS apply to all properties in the three Old Towne historic districts, but a different range of standards are used for contributing versus non - contributing properties. Please visit the City's website gis /cityoforange.org /flexviewers/ HistoricPreservationViewer or contact Planning Division staff to determine if your property is a contributor to the historic districts. The different sections of the HPDS will apply based on the historical use of the property. The Standards for Historic Building Features apply to all contributing properties. The Standards for Historic Residential Buildings apply to all historic single - family and multi - family residences and any buildings that were constructed as residences and have since been converted to other uses. Similarly, the Standards for Historic Commercial Properties apply to historic commercial buildings and any buildings that were constructed for commercial use and have since been converted to other uses. Design guidelines for historic industrial properties are included in the Santa Fe Depot Specific Plan and will apply to projects involving changes to historic industrial properties. DESIGN REVIEW Design review is the approval process that ensures that projects in the historic districts conform with the HPDS and the Secretary's Standards. To streamline review of repairs and rehabilitation, many types of minor design review projects are delegated to staff of the Planning Division in the Community Development Department. These projects are reviewed by staff as Minor Design Review (MDR) applications. For work that qualifies for an MDR, you can contact staff to review application materials during a visit to the Planning Division at the Orange Civic Center. Major projects are reviewed by the Design Review Committee. The Design Review Committee (DRC) is a body of five professionals who have training, knowledge and experience with architectural and site planning projects and are appointed by the City Council. Members of the DRC may include landscape architects, architects, urban planners, engineers, and general contractors. At least two of the members must have professional experience with urban planning, architectural history or historic preservation. The DRC may also serve as an advisory body to the Planning Commission or City Council for projects involving substantial new construction. A summary of common projects and their required review is provided in a table on page 10. Minor Design Review (MDR): An MDR is required for minor work on both contributing and non - contributing properties in the historic districts. The MDR is a streamlined review process for projects involving repairs or minor alterations that do not result in a substantial change to the features or materials of the building. The applicant must file an MDR application with the Planning Division. The following projects may be reviewed through an MDR application: Repair or replacement of exterior doors, when compatible materials will be used Repair or replacement of windows, when compatible materials will be used Roof replacement, when compatible roof materials will be used Removal of non - historic building features and replacement with compatible features. This does not apply to removal of non - historic floor area of a building 7 Accessibility improvements, including ramps and handrails Foundation repair New fences or walls, when compatible materials will be used Replacement or expansion of hardscape in front or side yards when visible from the street Replacement of existing mechanical equipment or installation of new mechanical equipment Installation of solar panels New decks or patio covers not visible from the street New accessory structures less than 120 square feet or additions to existing accessory structures creating a total area under 120 square feet P Installation of new signs in conformance with an existing sign program; general maintenance, repair or refacing of existing signs; or installation of reversible window signs The majority of projects will be reviewed and approved administratively. However, ending on the complexity of the changes to the historic building, staff may refer your project to the DRC for final determination. If staff determines that your project does not meet the HPDS, it will not be approved until changes are made to bring the project into conformance with the Standards. You may choose to appeal staff's determination to the DRC. All appeals shall follow the process described in Orange Municipal Code Section 17 08 050, but shall be heard by the Design Review Committee. Design Review Committee (DRC): DRC is required for all major work on 2 both contributing and non - contributing properties in the historic districts. The applicant must file a Design Review application with the Planning Division, following the procedures outlined in Orange Municipal Code Section 17 10 070. The DRC will conduct a public meeting and make a determination on the proposed project. The Committee may approve, approve with conditions, deny or continue the project. A continuation may be granted if the applicant is willing to make changes to the project as recommended by the DRC. A DRC determination may be appealed pursuant to Orange Municipal Code Section 17.08.050. Larger or more complex projects may also require review by the Planning Commission and/ or City Council, depending on the review process required under the Orange Municipal Code. If the project has the potential to significantly impact a historic property, it may also require an associated environmental review process under the California Environmental Quality Act CEQA). Staff will advise you of the required approvals. The following types of projects are reviewed by the DRC and require a DRC determination: Addition to a contributing or non - contributing building Addition to a contributing or non - contributing accessory structure, resulting in a structure larger than 120 square feet Alterations to the roofline of any building New accessory structure greater than 120 square feet Demolition of contributing or non - contributing accessory structures Demolition of a non - contributing building Infill construction Relocation of a structure New signs or sign programs Visibility from the street is determined by Planning Division staff. Generally, visibility includes all portions of the front and side elevations that are visible from the adjacent street or sidewalk. Areas that would be visible but are currently obscured by landscaping are considered to be visible. Demolition of any building requires Demolition Review under OMC 17.10.090. The proposed replacement project must be reviewed at the same time as the proposed demolition. Building permits will be required for the majority of DRC projects and will only be issued by the Building Division after approval by the DRC. Exemptions: The following types of projects are exempt from the DRC or MDR process for both contributing and non - contributing properties. Interior alterations that do not cause a change to the exterior appearance of the building Rear yard landscape or hardscape that is not visible from the street and does not involve the removal of any historic features of the site Minor front and side yard landscape projects, involving installation of new plantings. This exemption does not apply to installation of new fences, walls or hardscape or to the removal of mature trees. The City's Tree Preservation Ordinance protects mature and/ or historic trees from removal.

Review the HPDS and determine which sections apply to the project. Be sure that you are addressing all applicable design standards during project development. 2. Review the property's context and building's features. After reviewing the HPDS, determine what are the character - defining features of the property and how they will be affected by the project. Look at how the project will fit into the neighborhood in which it is located. The project should address the design standards related to both the context and the individual buildings on the property. 3. Consult with Planning Division staff. We strongly recommend that you meet with staff prior to creating final drawings or submitting an application. Staff can provide you with guidance to identify how your project meets or is in conflict with the HPDS. 4. Engage professional design help. You are encouraged to engage an architect with experience in historic preservation to assist with the project. Working with a professional to develop a clear set of project drawings will likely save time and money during the review process. While this is not required, it is strongly encouraged for all projects. 5. Prepare and submit a complete application for review. A DRC /MDR application must be submitted for all projects requiring review. The type of application will depend on the scope of work. The application must provide enough information to adequately understand the proposed project, and typically must include drawings. The drawings should be to scale and clearly depict the work proposed. 6. Staff reviews the application. For a MDR application, staff will review your application when you submit it at the Planning Division Counter. If the information provided is complete and the project meets the HPDS, it will be approved at the counter. For a DRC application, staff will review your application within 30 days of submittal. Depending on the complexity of your project, staff may request additional information or revisions to the plans. Staff will schedule the project for a DRC meeting and will make a recommendation to the Committee only after you have responded to comments and your application has been deemed complete. 7. Attend the scheduled Design Review Committee meeting. The Design Review Committee meets on a regular schedule established by City Council resolution and available on the City website: cityoforange.org. You and any design professionals who worked on the project should attend the meeting to answer questions and comments from the DRC. You will receive a copy of the meeting agenda and staff report for your project in advance of the meeting. 11 MAP OF OLD TOWNE HISTORIC DISTRICTS Maps of the Old Towne historic districts are also available on the Historic Preservation page of the City website: www.cityoforange.org. t Downtown Core Cad Timwww Orrqe NR ju**w*eD%trECI 09971 EM Old Tamw Orange Local 0 Dket"C' 11991 PlUm NR 1'I.16W. 0111trid 119821 A4 +1 • roil$ '% - f Y Y '. !

The following is a summary of the character - defining features of the Plaza Historic District and the Old Towne Historic Districts (both local and National Register). These features are critical to the significance of the historic districts and should be preserved as part of any proposed project in the historic districts. These character - defining features include specific aspects of setting, mass, scale, design and materials. You should consult these lists to confirm that any project involving rehabilitation or new construction retains these character - defining features. The Cypress Street Barrio is not a separately designated historic district but it is an important neighborhood within the Old Towne Historic Districts. The barrio's cultural significance comes from its long- standing history as the center of the Mexican and Mexican American community in Old Towne. Thi: heritage is described in a separate section below. Similarly, the Railroad /Packinghouse Corridor is not designated as a separate Plaza Park, ca.1915 historic district, but it reflects the character of Orange's early agricultural heritage. The history and significance of the Railroad /Packinghouse Corridor is described in the Santa Fe Depot Specific Plan. For design guidelines specific to historic industrial buildings in this area, consult the Santa Fe Depot Specific Plan on the City's website. Character- Defining Features of the Plaza Historic District The Plaza Historic District is the original commercial downtown of Orange. The late 19th and early 20th century buildings surround Plaza Park at the center of a roundabout. Plaza Park was laid out in 1886 and retains its pattern of walkways and landscape areas from that period. The fountain at the center of the park dates to 1937. Period of significance: 1871 -1931 Commercial district anchored by elliptical Plaza Park and round- about street configuration at the intersection of Chapman Avenue and Glassell Street Buildings located at the sidewalk with no front or side setbacks Dense, primarily two -story development with commercial storefronts at the ground floor and office or residential uses above Flat roofs with parapets and decorative cornices Brick or other masonry construction Cast iron or wood storefront elements at ground floor 10 Plaza Park, ca.1932 13 Wood windows on upper floors Decorative brick patterns Remnants of historic painted signs Character- Defining Features of the Old Towne Historic District The Old Towne Historic District reflects the early development of Orange. It includes the late 19th and early 20th century business district around the Plaza, surrounding residential neighborhood and industrial area along the Atchison, Topeka & Santa Fe Railroad. The Historic District includes a variety of architectural styles in commercial, residential, institutional and industrial buildings. Period of significance: 1888 -1940 Rectangular lots with a grid street pattern. Near Hart Park on the south side of the historic district, there are some curving streets reflecting the topography and layout of the park Tree -lined streets with planted parkways Concrete sidewalks and walkways Fluted concrete street lights with acorn globes Detached residential buildings with similar front and side setbacks Small, utilitarian detached accessory buildings at rear of lots Primarily gable, hip, or flat roofs, corresponding to the architectural style of the buildings Primarily wood or stucco cladding. Some brick or stone cladding, mostly used for decorative accents at porches and foundations 11 Residential architectural styles include Folk Victorian, Craftsman, Spanish Colonial Revival, Tudor Revival, and Prairie Front porches transition between the public sidewalk and private space of the house Industrial buildings, particularly associated with the historic citrus packing industry, located near the Atchison, Santa Fe & Topeka Railroad South Glassell Street, ca. 1920 Plaza Park, 2005 14 Cypress Street Barrio The Cypress Street Barrio is a small historically significant neighborhood in the northeast corner of the Old Towne historic districts. The neighborhood first developed in the 1890s with construction of several fruit packinghouses along the Atchison, Topeka & Santa Fe Railroad. The growth of the citrus industry brought Mexican American workers and their families to the area to pick and pack the flourishing crops. Early on, Mexican American families in the barrio lived in older houses that were moved to the properties surrounding the railroad. As the neighborhood developed, additional houses were constructed, ranging from simple tenements to Queen Anne cottages and Craftsman bungalows. The residences were interspersed with small businesses including grocery stores, bakeries, tortillerias, restaurants, barbershops, pool halls, and automobile shops, most owned and operated by the Mexican American families living in the neighborhood. Faced with segregationist policies and attitudes from the white residents of Orange, the barrio's residents developed a rich tradition of institutions to support the neighborhood, including The Friendly Center which provided healthcare, homemaking classes and childcare to residents and jamaicas, or church street fairs held on Cypress Street. Adapted from the Cypress Street Barrio Historic Context Statement by Chattel, Inc.) Bounded approximately by Rose Avenue to the north, Glassell Street to the east, Almond Street to the south, and the Atchison, Topeka & Santa Fe railroad to the west Packinghouses and other industrial buildings along the railroad. Development was closely tied to the citrus industry and the Mexican American workers who supported the industry Primarily one story residential buildings in a variety of early 20th century architectural styles. Features of these houses are similar to the rest of the Old Towne Historic District Small number of commercial buildings that housed small businesses or institutions serving the neighborhood. Important examples include: Luna's grocery store at 418 N. Cypress Street The Friendly Center at 424 N. Cypress Street Cypress Street School at 544 N. Cypress Street and Killefer School at 541 N. Lemon Street The mural "El Proletariado de Aztlan" at 442 N. Cypress Street, painted in 1979 by Chicano artist Emigdio Vasquez, serves as a neighborhood landmark South Lemon Street, ca. 1910 Lewis Court, North Cypress Street, ca. 1941 15 Santiago Orange Growers Association, ca. 1928 Architectural style sheets with information on common types of historic residential architectural styles in Old Towne are available on the City's website or at the Planning Division Counter at the Civic Center. Please consult these style sheets when you are planning a project to ensure that any changes preserve the historic character of the property. 16 STANDARDS FOR HISTORIC BUILDING FEATURES The following standards address the treatment of specific elements anc features of a historic building. These standards apply to all building types, whether residential, commercial, institutional, or industrial. Roofs The roof is a major character- defining feature for most historic buildings. Similar roof forms repeated on a street help to create a sense of visual continuity for the neighborhood. Roof pitch, materials, size, orientation, eave depth and configuration are all distinct features that contribute to the overall integrity of a historic roof. The 13 location and design of chimneys as well as decorative features such as dormers, vents and finials are also often character - defining roof features. Certain roof forms and materials are strongly associated with particular architectural styles, and altering roof shapes or materials may impact the integrity of the historic building. Care should be taken to ensure that the character of the roof is retained. I . The historic roof shall be preserved and maintained. a. Changing the slope or orientation of a historic roof is inappropriate. b. The depth of the eaves is an important character - defining feature of a historic building and should be preserved. Adding fascia, cutting off exposed rafter tails, or boxing in exposed rafters is inappropriate. c. Other important historic roof details include vents, corbels, dormers, finials and built -in gutters. These elements should be preserved and repaired as necessary. 2. Specialty historic roofing materials shall be preserved. a. Deteriorated sections of specialty historic roofing materials, such as clay tile, may be replaced with materials that exactly match the historic materials. 3. Replacement roofing materials should be substantially similar in scale, texture, and color to materials used historically. 4. New dormers should not be added to elevations that face the street. 5. New skylights should not be added to elevations that face the street. a. New skylights must be flush with the roof plane. b. New roof vents should be low profile and coordinated with the color of the roofing material. 17 18 Features such as corbels, brackets, shaped rafter rails, and dormers contribute to the architectural style and historic significance of a building FRONTING D GABLE ROOF 4-2 PORCH ate' Common roof forms on historic buildings in Old Towne HIPPED CROSS GABI ROOF FORM PORCH DUTCH CLII GABLE ROC OF FORM i FRONTING DOUBLE GABLE ROOF FORMGABLEROOFFORM HIPPED ROOF FORM DUTCH CLIPPED GABLE ROOF FORM CROSS GABLE ROOF FORM GAMBREL ROOF FORM FLAT (PARAPET) ROOF FORM Windows and doors are essential components of the character of a historic building. The placement, grouping and size of historic openings on each elevation are important parts of each building's architectural style. The construction and materials of each window or door are also integral to the building's character. Because windows and doors are so critical to the character of a historic building, they generally should not be replaced. Replacement is only appropriate where the window or door is too deteriorated to be repaired. To maintain the character of the historic building, the replacement must exactly match the original in dimensions, materials and details, which often requires building custom windows or doors. Maintaining historic windows and doors is often the most cost - effective method to preserving the character of your home while improving energy efficiency. The windows and doors in your home may be more than 100 years old and, with regular maintenance, can outlast modern replacements. Historic windows and doors shall be preserved and maintained. Do not alter the location, number, size, pattern, or proportion of historic windows and doors on elevations visible from the street. Enclosing a historic opening or adding a new opening on elevations visible from the street is generally inappropriate. c. Historic grillwork on windows should be retained. New security bars should not be added to c windows or doors on street - facing elevations. d. Simple screens that are compatible with the architectural style of the building are appropriate. Typically, wood frame screens will be most compatible with houses in the historic district. Clear anodized aluminum screens are generally not appropriate. FIXED SASH - TRIM PATTERNED LEADED GLAS!

Awnings and shutters should only be used where they are compatible with the architectural style of the building. They should be similar in materials, design, and operation to those used historically and should match the shape of the window on which they are installed. 2. Historic windows and doors with signs of damage or deterioration shall be repaired, rather than replaced. a. Repairs should follow the recommendations of NPS Preservation Brief 9 — The Repair of Historic Wooden Windows and other applicable technical guidance from NPS Technical Preservation Services. See Appendix B for a complete list of Preservation Briefs. 71 b. If glass in historic windows or doors must be replaced, clear glazing is appropriate. Reflective coatings or dark tints are not appropriate. Limited use of frosted or opaque glass may be appropriate on side or rear elevations, if privacy from adjacent properties is a concern. 3. A historic window or door that is beyond repair may be replaced in kind. i AWNING CASEMENT Ln SINGLE HUNG CASEMENT WITH CENTER HORIZONTAL RAIL TO SIMULATE SINGLE HUNG Typical window styles a. The replacement window or door should match the size, shape, arrangement of panes, materials, method of construction and profile of the historic feature. b. The replacement window or door will likely need to be custom -made to match the historic design and materials. 4. Restoring original windows and doors that have been removed or altered is encouraged. a. If a window or door has been replaced with non - historic materials, a new window or door that is compatible with the architectural style of the building may be installed in its place. Design of the replacement should be based on historic photographic evidence. If no such evidence exists, the replacement should be based on a combination of physical evidence (indications in the structure itself) and evidence of similar openings on the building and on buildings of the same architectural style. The new window or door should reflect the size, shape, materials, and arrangement of panes of historic features. 21 Architectural details and building materials are key to each historic building's character. The characteristics of primary building materials, including the scale, texture and finish, and features such as lintels, brackets, cornices and columns, also contribute to a particular architectural style. Decorative details should be maintained and repaired to enhance their original character. Regular maintenance of these features will prolong the life of the historic building. Repairs may include stabilizing or consolidating deteriorated portions of the historic materials. These options should be carefully considered before an architectural detail is replaced. 1. Historic architectural details and building materials shall be preserved. a. Regularly check historic materials for conditions such as moisture accumulation that can cause deterioration. b. Do not remove historic materials that are in good condition. i. All materials weather over time and a scarred or uneven surface does not mean that a particular building element is too deteriorated to be preserved. C19 ii. Materials that show signs of age are part of the character of historic buildings. c. Distinctive architectural features and examples of skilled craftsmanship are particularly important to the character of a historic building and should receive sensitive treatment. Distinctive features may include decorative elements, such as brackets, exposed rafter tails, and columns, or the pattern of materials used in construction, such as decorative shingles or masonry. Removing or covering these details is inappropriate. d. Do not alter historic finishes. Unpainted historic masonry or wood elements should not be painted. Similarly, wood elements that were painted historically should have a painted finish to protect the materials from deterioration. Materials like this stone porch are important character - defining features 22 Architectural Details and Building Materials 2. Historic materials shall be repaired in place to the greatest extent feasible. a. Repairs should maintain as much historic material as possible by patching, splicing and consolidating deteriorated materials. EXISTING HISTORIC SIDING AND TRIM DETAILS TO REMAIN OR BE REPLICATED EXISTING FLOOR STRUCTURE TO REMAIN b. Materials that can be repaired in place should not be removed or replaced. c. When cleaning or repairing historic materials, use the gentlest means possible. 3. Historic materials that are too deteriorated to be repaired shall be replaced in kind. a. Replacement is a last resort when historic materials cannot be repaired. b. Replacement should be limited to only those portions of the historic elements that cannot be repaired. For example, complete replacement of a window is not appropriate if only the sill is deteriorated beyond repair. EXISTING STONE FOUNDATION TO REMAIN EXTERIOR OF STRUCTURE I NEW CONCRETE STRUCTURAL FOUNDATION WALL AND/ OR FOOTING, TO BE DESIGNED BY A STRUCTURAL ENGINEER EXISTING BASEMENT OR CRAWL SPACE -- The foundations of historic houses frequently have decorative brick, concrete or stone work. Seismic retrofit and foundation repairs should be accomplished from the interior crawlspace or basement to avoid removing or damaging these historic materials c. Replacement elements shall match the historic design, materials, scale, size, proportion, finish, texture, details, profile, reflectivity, and durability. d. Synthetic replacement materials, such as vinyl siding or synthetic stucco, are not appropriate for use on a historic building. e. Replacement of a historic material with an alternate material may be considered in limited circumstances. i. The proposed alternate material will be evaluated using the criteria described in National Park Service Preservation Brief 16: The Use of Substitute Materials on Historic Building Exteriors. ii. The applicant will provide justification for the use of an alternate material including information on the availability and performance of an in -kind replacement material. The applicant will also provide samples and specifications of the proposed alternate material, including information on performance and durability. Technical guidance for specific historic materials is available from NPS Technical Preservation Services and should be consulted when planning for repairs to historic building features. A list of this guidance is provided in Appendix B. 23 Y P Historic materials, such as wood, stone, plaster, tile and brick, contribute to the character of historic neighborhoods 24 4. Removing non - historic features where possible is encouraged. a. In some cases, these later additions may be obscuring original historic materials that can be recovered. 5. If historic features are missing, replacement should be based on historic documentation. If historic photographs or physical evidence, such as remnant marks on the structure, are not available, the design of replacement details should be based on similar elements on buildings of the same architectural style in the neighborhood. 6. Adding architectural details or elaborate decorative elements that are not appropriate to the architectural style of the building or are not clearly based on evidence from the building's history should be avoided. 7. Paint colors that are appropriate to the period and style of the building are strongly encouraged. Mechanical Systems Mechanical systems help to adapt historic buildings to contemporary uses. With careful planning, most can be located where they cannot be seen from the street and will not detract from the character of the historic district. EXISTING HISTORIC GARAGE NEW TRASH ENCLOSURES NOT VISIBLE FROM THE STREET NEW A/C UNITS GROUND OR ROOF MOUNTED NOT VISIBLE FROM THE STREET NEW SOLAR PANELS GROUND OR ROOF MOUNTED NOTVISIBLE FROM STREET - NEW SATELLITE DISHES ROOF MOUNTED NOT VISIBLE FROM STREET EXISTING HISTORIC RESIDENCE P(- LOCATE SKYLIGHTS SO THEY ARE NOT VISIBLE FROM THE STREET EXISTING DRIVEWAY STREET Examples of appropriate locations for mechanical equipment and trash enclosures 25 a. Equipment mounted directly on a historic building should be attached using the least invasive method, without damaging historic features. b. Roof- mounted equipment is only appropriate on flat roofs with existing parapet walls to fully screen the equipment. c. Satellite dishes and similar equipment shall be located in areas that are least visible from the street. d. Ground - mounted or building- mounted equipment shall be appropriately screened from view from the street. 2. Solar panels shall be located in areas that are least visible from the street. a. Rooftops of detached garages or rear - facing roofs of primary buildings are the most appropriate locations for solar panels. T On flat roofs with parapet walls, solar panels may be installed on the full extent of the roof, provided that the panels are not visible above the parapet walls. c. On sloped roofs, solar panels shall be installed on the rear 50 percent of the roof of the primary building. d. On corner lots, for buildings with sloped roofs, solar panels shall be installed on the interior 25 percent of the roof of the primary building. e. If the permitted locations for solar panels in Standard 2c or 2d cause the installation to be visible from the street, staff may require the proposed system to be modified to reduce its visibility. The modification shall not significantly increase the cost of the system or significantly decrease its efficiency, as defined by California Civil Code Section 714. f. Solar panels shall be parallel to the roof plane, shall not extend more than 10 inches above the roof surface, and shall not overhang or alter existing rooflines. g. Solar panels shall be attached to roofs using the least invasive method possible, without damaging historic features. h. Solar panels shall be neatly arranged in a rectangular format with no gaps between the panels. The back side of this roof would be an appropriate place for solar panels 26 1. Mechanical equipment shall be located in areas not visible from the street. STANDARDS FOR HISTORIC RESIDENTIAL BUILDINGS These standards apply to single - family structures, multi - family structures, and structures that were originally constructed for residential use and have since been converted to other uses. The Standards for Historic Building Features also apply to all historic residential buildings. Setting The setting, or streetscape, is a critical component of the sense of place that is important to historic districts. Front yards in historic residential neighborhoods are typically characterized by a progression from the public street to private interior spaces. Streetscapes frequently have common front and side yard setbacks shared by the majority of buildings on the block. Preservation of this streetscape pattern is essential. The streetscape includes the visual character of the street, sidewalks and walkways, buildings, landscape, and street lighting working in concert. Relationships of buildings to each other, setbacks, fencing patterns, views, driveways, walkways, lighting, and street trees all contribute to the character of historic streetscapes. 1 - The prevailing pattern of open space in the front and side yards of contributing properties should be preserved. 2. Historic walkways, driveways, and other hardscape features in the front yard shall be preserved. a. Unpainted historic walls, curbs, or planters should not be painted. Landscaped parkways and front yards flanking the sidewalk create a pleasant place to walk 3. Repairs or expansion of paving or hardscape features should match the historic features in materials, color, texture, and finish. a. The appropriate concrete paving material for driveways or walkways is a natural grey concrete, textured to expose the fine aggregates through an acid wash or light retardant finish. GARAGE w - - w+ w Q mm M 4J HOUSE STREET Typical pattern of residential development in Old Towne 27 Alternate paving materials in front or side yards visible from the street may be considered, if they are compatible with the building and the streetscape. Parkways, front yards, and side yards should be reserved for landscape. Paving or non - porous surfaces should be minimized. Parking areas should be located at the rear of the site and should be screened from public view by appropriate fencing or landscaping. Widening an existing driveway is generally not appropriate. Driveways between 9 and 12 feet are generally appropriate and provide adequate room to maneuver vehicles. Driveways may have a center planting strip. The planting strip should be a minimum of 18 inches wide. Front yard fencing may be installed, provided that it matches the prevailing pattern of fencing in the streetscape. Front yard fencing should be low and transparent, using materials that are in keeping with the character of the house. Wrought iron fences may be appropriate for Spanish Colonial Revival or Tudor Revival houses. Wood picket fences may be appropriate for Craftsman or Folk Victorian houses. Utilitarian wire and wood or steel post fences were frequently used during the historic districts' period of significance and are an appropriate style for new front yard fencing. Solid masonry walls in the front yard are generally not appropriate. The use of a traditional color palette is encouraged. g. Front yard fences are strongly encouraged to have an 18 -24 inch planting strip between the sidewalk and the fence. 8. Rear yard opaque fencing for privacy may be appropriate, provided that the design and materials are compatible with the building and the neighborhood. Compatible fence with landscape area next to sidewalk 28 a. If a six foot rear or side yard fence is located next to the street, it is strongly encouraged to have a 24 inch planting strip between the sidewalk and the fence. 9. Vinyl, chain link, and plastic fences are prohibited. 10. Mature trees and hedges should be retained whenever possible or replaced with matching plantings as necessary. 11. Drought tolerant alternatives to lawns may be appropriate if the alternatives are compatible with the character of historic front yards and parkways. Front yards are generally characterized by low- growing lawns with foundation plantings at the base of the buildings or cottage gardens with a variety of plantings. Low -water alternative plant species appropriate to the climate may be used, if they are compatible with the historic character of front yards and parkways. In areas visible from the street, yards that are primarily gravel, mulch or unplanted soil are generally not compatible. Compatible drought - tolerant landscape 12. Artificial turf is prohibited in parkways, front yards, and side yards visible from the street. Porches In residential neighborhoods, porches function as an outdoor living space and a sheltered transition into the house. The various components of porches, including steps, balustrades, columns, pilasters, doors, and cornices, and decorative embellishments, add to the character of historic neighborhoods and help to establish a sense of community. Porches are often a primary character - defining feature of a historic house. 1. Historic porches shall be preserved. a. Maintain the location, shape, details, posts, railings, balustrades, and decorative brackets of the historic porch. b. Repair deteriorated decorative elements or replace missing elements to match the existing. 0 /10 c. Alterations for accessibility should be designed and built to be minimally visible and to require minimal alterations to Historic porch with turned historic materials, while allowing equal access to the building. wood columns 29 Front porches in Old Towne have a variety of piers and columns, all Historic porches may include rear or side service porches, which are typically characterized by a wood -sided half wall with a band of windows above. A service porch might look like an addition because it may have a different roof line than the house. These porches usually started as screened indoor - outdoor spaces early in the building's history and have been gradually enclosed over time. Intact service porches are character - defining features and should be preserved. 2. Original steps should be preserved. If the steps are so deteriorated that they must be replaced, they should be replaced utilizing compatible materials. a. In general, wood steps are appropriate for a wood porch and concrete steps are appropriate for a concrete porch. However, other combinations do occur on contributing buildings. All or part of a historic porch or entrance should not be enclosed in areas visible from the street. In many cases, historic porches did not include a guardrail, and one should not be added unless there is evidence that a guardrail existed on the porch historically or there is a safety issue to be addressed. 30 of which are character- defining features of these historic houses 5. The addition of a handrail for safety at the front steps may be appropriate, if the handrail is simple in design and uses materials compatible with the historic building. 6. If porch posts have been replaced with non - historic or non - compatible materials, replacing those elements to match the historic building in scale, proportion and materials is encouraged. a. The design of replacement porch posts should be based on historic photographs, physical evidence, and study of buildings with a comparable architectural style. 7. New wood posts, handrails, and guardrails should use concealed fasteners. Garages and Accessory Structures Many historic properties in Old Towne contain small accessory structures in the back yard. These structures are typically utilitarian carriage houses, garages or sheds, constructed to store equipment or vehicles. Some accessory structures reflect the architectural style of the house, but many are simple wood frame structures with modest architectural details and materials. In many cases, these structures reflect the development pattern of the late 19th and early 20th centuries in Orange. The historic resources survey form for a property may not identify accessory structures as historic features of the site. However, these structures may be character - defining features of the historic property and contribute to the character of the historic district. The following criteria will be used to determine if an accessory structure is a character - defining feature of the property. If an accessory structure: 1) was constructed during the Historic District's period of significance (1888- 1940); and 2) retains physical features from that time period Then it is likely a character- defining feature of the property and should be preserved. If you would like to find out if an accessory structure on your property may be a character - defining feature, please provide the City's Historic Preservation Planner with photographs of the structure. 1. Historic accessory structures shall be preserved. a. Changes to accessory structures shall comply with the Standards for Historic Building Features. Compatible garage doors r 31 Newly constructed house on East Chapman Avenue, ca. 1920. Note the garage behind on the car on the right b. A one story addition to the side or rear of an accessory structure may be an appropriate way to provide additional parking or storage area. c. The addition of a new second floor or substantial modifications to the rooflines of garages or accessory structures are inappropriate. d. Adding small dormers to an existing roof may be appropriate, provided that the scale, design and materials of the dormers are compatible with the historic accessory structure. d. Historic garage doors are typically utilitarian wood doors that swing open or slide on a metal track. If the accessory structure has a historic garage door, it should be preserved. i. A replacement of a non - historic garage door should be compatible with the materials and design of the historic accessory structure.

A garage attached to a historic house is generally inappropriate. New garages and accessory structures typically should be located behind the rear wall of the historic house. b. New garages or accessory structures should not compete visually with the historic residence and should be subordinate in height, width, and area in comparison to the existing primary structure. similar materials, windows, roof patterns, and simplified architectural details. Basic rectangular forms, with simple hip or gable roofs, are appropriate for most new garages and accessory structures. e. Single -bay garage doors are more appropriate than double -bay garage doors on new structures. STANDARDS FOR HISTORIC COMMERCIAL BUILDINGS The following standards apply to existing commercial structures and structures that were originally constructed for commercial use and have since been converted to other uses. The Standards for Historic Building Features also apply to all historic commercial buildings. Both the Historic Preservation Design Standards and the Santa Fe Depot Specific Plan Design Guidelines apply to historic industrial buildings. Setting and Building reatures The Old Towne Historic District includes several commercial areas with distinct character. The Plaza Historic District is the earliest commercial center in Orange. It consists primarily of the properties fronting Glassell Street and Chapman Avenue one block around Plaza Square. These properties create a continuous street face with zero setbacks from the sidewalk. Large storefronts on the ground floor are oriented toward pedestrians with offices or apartments above. Parking areas are located at the rear of buildings. The Downtown Core encompasses eight blocks around the Plaza bounded by Maple Avenue on the north, Grand Street on the east, Almond Avenue on the south, and Lemon Street on the west. The perimeter blocks of the Downtown Core provide a transitional space between the taller, denser development of the Plaza and the surrounding residential a — CHARACTERISTIC FEATURES Elements of a historic commercial building 34 c.

Accessory structures may reflect the architectural style of the existing house through neighborhoods. The majority of these properties retain the pedestrian - oriented character of the Plaza with large storefronts on the ground floor. Other properties represent later development oriented toward automobile traffic interspersed with a small number of single and multi - family residences. The Spoke Streets are Glassell Street and Chapman Avenue outside of the Downtown 9 Core. The majority of properties fronting these streets contain historic residential buildings converted to commercial uses. These properties retain their residential character with landscaped front and side yards and modestly sized buildings. Rear yards may have Historic storefront, ca. 1905 been converted to surface parking lots. Later commercial development, particularly on Chapman Avenue, is larger in scale and more oriented toward automobile traffic. 1. Historic sidewalk features, including street lights, should be preserved. a. Historic sidewalks may include unique score patterns, textures or materials that shall be preserved. 2. Primary building entrances shall be oriented toward the street. a. Relocating the primary entrance to the rear of a building to face an alley or parking lot is inappropriate. 3. Outdoor dining is encouraged in front of buildings in the Plaza and Downtown Core. a. Outdoor dining in the public right of way in the Downtown Core requires issuance of an Outdoor Dining Permit. Consult OMC Chapter 12.18 for the requirements of the Outdoor Dining Permit. b. Fences or other barriers in the sidewalk around the outdoor dining area are prohibited on Chapman Avenue or Glassell Street. Removable fences or other barriers may be considered in the dining zones in the quadrants around the Plaza. 4. When commercial uses occupy historic residential buildings, the front yard landscaping should be retained. a. Parking in the front yard is prohibited. b. Pedestrian - oriented uses, such as outdoor dining, may be considered in the front yard area, provided that the use can be accommodated with limited additions of paving or non - porous surfaces. 35 5. Exterior light fixtures shall be compatible with the architectural style of the building. a. Animated or flashing lights are prohibited. b. Colored lights are prohibited, except for exposed neon used in signage. c. Lighting should typically have a warm color temperature. FRAME TRANSOM WINDOW FRAME d. Light sources on building and site lighting should be shielded to prevent glare and light spill onto neighboring properties. DISPLAYWINDO% 6. Trash enclosures and utility and service cabinets shall be integrated SIL into the design of the building and site and shall be located at secondary elevations to the greatest extent feasible. APROr 7. The height of a new building or an addition to an existing building shall not exceed two stories, 30 feet or the height of adjacent buildings, whichever is the lesser height. a. In the Plaza Historic District and Downtown Core, a new story added on top of an existing building may be appropriate under limited circumstances. An upper floor addition shall not cover the entire footprint of the existing building and should be set back from the street - facing elevations of the building. BULKHEAI b. Additions to existing buildings to provide elevator access to upper floors may exceed the height of adjacent buildings. 8. In the Plaza Historic District, new construction with exposed sloped roofs is prohibited. 9.

For new construction, a 15 foot landscape area is required between all parking areas and any public right of way. 12. For existing construction, landscape areas should be provided between all parking areas and any public right of way to the greatest extent feasible. 36 STOREFRONT WINDOW Storefronts One of the most important character- defining features of a historic commercial building is the storefront. Although storefront character varies from building to building, there are specific features common to almost all storefronts. The most typical historic storefront configuration consists of a low base wall, known as a bulkhead, topped by large panes of glass, or storefront glazing. The main store entrance is located in the center or to one side of the storefront, often recessed from the main facade. Often, storefronts will include a second, less prominent door leading to second story offices or apartments. Above the storefront glazing, there is often a band of narrow, horizontal panes known as transoms or clerestory glazing. The store's signage was historically located on awnings over the storefronts, was painted on the glass itself, or was located in a sign area above the clerestory or transom glazing. Historic commercial storefronts and their component elements, such as display windows, bulkheads, transoms, prism glass, doors, pillars, and pilasters, shall be preserved. a. Do not alter the location, number, size, pattern or proportion of historic openings, particularly on primary elevations. b. Interior spaces should be designed so that new partitions do not impact the appearance of the historic storefront. 2. Transparent, clear glazing is appropriate for ground floor storefronts. Reflective coatings or dark tints AWNING on storefront glazing are prohibited. SCISSORS -ARM AWNING IUL VALANCE FIXED -ARM AWNING I e 37 3.

Removing storefront glazing to create recessed outdoor areas at the front of commercial buildings is generally discouraged and will only be appropriate if the building is a non - contributor to the Historic District or if the building has a documented history of a recessed storefront in that location. Security bars or roll -down gates are prohibited. Awnings should be similar in materials, design, and operation to those used historically. An awning should typically fit within each of the building's structural bays, exactly over the display windows. Internally illuminated awnings or vinyl awnings are prohibited. c. New awnings shall use anchors and attachments that do not damage the historic building materials and /or structure. 6. Reconstructing historic storefronts that have been removed or altered is encouraged. If a historic opening has been replaced with non - historic materials, a new one that is compatible with the architectural style of the building may be installed in its place. Design of the replacement should be based on available photographic evidence. If no such evidence exists, the replacement should be based on a combination of physical evidence indications in the structure of the building) and evidence of similar elements on buildings of the same architectural style in the historic district. The new opening should reflect the size, shape, design and materials of similar openings. j T O 38 Signage All new signs must meet the requirements of Orange Municipal Code Chapter 17.36, in addition to the signage standards below. Where OMC Chapter 17.36 and the Historic Preservation Design Standards overlap, the HPDS will take precedence.

D I I i — — I 42 STANDARDS FOR NEW CONSTRUCTION RELATED TO HISTORIC BUILDINGS Additions A small addition may be an appropriate way to encourage contemporary uses of a historic building. A thoughtfully designed addition will have limited impacts to the streetscape of the historic district and the materials of the historic building. The compatibility of an addition is based on a number of elements related to mass, scale, design, materials and detailing. If you are considering an addition to your historic building, please contact Planning Division staff early in the design process to discuss opportunities and constraints related to new construction in the historic district.

Compatible additions should be smaller in mass, scale, and volume than the historic building. Two story additions to one story buildings are inappropriate. Conversion of attic space to habitable area within the existing roofline is encouraged, provided that the conversion does not require substantial changes to the form of the roof. 2. An addition should be located at the rear of the building, away from street facing elevations. i. After the addition is constructed, it should be clear which part of the building is historic and which part is new. The addition should be differentiated from the historic building, while still being compatible with its scale, massing, materials, and features. A line of demarcation or offset in the wall plane between the historic building and the addition is strongly encouraged. US on nistoric ounamgs 4. Additions to historic buildings shall use traditional building materials appropriate to the style of the historic building or the period of significance of the Historic District. a. New building materials on the addition may differ from the historic materials in size, scale or profile.

If the addition were removed in the future, the essential form and integrity of the historic building should be unchanged. b. The roofline of the historic building should be retained on elevations visible from the street. Infill Construction Infill in historic districts may consist of constructing a new building on a vacant lot (primary building) or constructing additional buildings (secondary buildings) on a lot containing an existing building. Successful infill construction takes cues from the surrounding historic neighborhood and its buildings without creating an exact replica of a historic architectural style. New construction should be consistent with the mass, scale, materials, height, roof form, setbacks, and pattern of windows and doors of existing buildings on the street. The site design of an historic structure is an essential part of its character. The spacing and location of buildings on each lot within an historic neighborhood usually establishes a rhythm that is essential to the character of the neighborhood. The grouping of buildings, with uniform setbacks and street features, gives each neighborhood a strong sense of place. One of the first steps to designing an infill building is to look at other buildings on the block and determine what are the common design elements that create a consistent streetscape and neighborhood character. Contemporary interpretations of historic architectural styles are not discouraged, but the primary goal of infill construction should be to create a building that responds to its context within a historic neighborhood. 1. The location of new primary and secondary structures on a lot should be consistent with the historic pattern of front and side yard setbacks. 2. New buildings should be similar in mass and scale to surrounding buildings. a. If a new building is larger than its neighbors, it should be modulated so that the appearance of the mass is located back from the street and is less visible. b. Properties with new construction are recommended to use the average Floor Area Ratio of historic properties on the surrounding street as a model for compatible new development. See the description on the following page for instructions on determining an appropriate Floor Area Ratio for your project. 3. The height and roof form of a new building should be comparable to surrounding historic buildings. a. Roofing materials and details should be similar to those found on historic properties. b. Dormers should be similar in size and style to historic properties. 46 6. Window and doors openings in an addition should reflect the size, shape, and pattern of 4. A new primary building should have a main entrance and fagade parallel to and facing the street. 5. The progression of public to private spaces from the street should be maintained. A sheltered building entrance or front porch may be appropriate to create a transitional space from the street to the interior of the building. b. New construction should have a similar pattern of windows and doors on elevations visible from the street to those found in surrounding historic buildings. 7. The use of traditional building materials found on historic buildings in the Historic District is encouraged for new construction. Exterior materials shall be compatible with the size, scale, design, texture, reflectivity, durability and color of historic materials used on comparable historic buildings in the Historic District. b. Use of simplified versions of traditional architectural details is encouraged. c. Alternates to traditional building materials may be considered, if the alternate material is compatible with the design and appearance of comparable historic features on similar contributing buildings in the Historic District. 8. The height, mass and scale of new secondary buildings should be minimized as much as possible. a. In general, secondary buildings should be no taller than the primary building. In limited areas, secondary buildings may be taller than primary buildings, if this condition is already typical of the streetscape of the surrounding blocks. b. The design of secondary buildings should be subordinate to the primary building on the lot. Historic accessory structures were typically utilitarian buildings with limited decorative elements. Basic rectangular building forms and simple roof configurations are appropriate. 9. Infill construction should adhere to the sections on Standards for Historic Residential Buildings — Setting or Standards for Historic Commercial Buildings — Setting. 47 FLOOR AREA RATIO IN THE HISTORIC DISTRICTS Floor Area Ratio (FAR) by Separate Floor Area Light Grey = First Floor Area (not counting porches) Medium Grey = Second Floor Area Dark Grey = Habitable Area over 5 Feet in Height i fl 5'2' , St FLOO 1 st FLOOQI Block Floor Area Ratio (FAR) 0 Number of Stories First Floor FAR including garages) Second Floor FAR Total FAR FAR Range Average FAR Floor Area Ratio Example: Lot Area 6,200 sq.ft. 1st Floor Area (Without Open Porches)1,120 Garages & Accessory Structures 420 Total First Floor Area 1,540 1 st Floor Area Divided by Lot Area 03 1,540 / 6,200 =.25 FAR 03 .03 Second Floor Area 625 Any Attic Area over 5 Feet in Height 180 Total 2nd Floor Area 805 Second & Attic Area Divided by Lot Area 805 / 6,200 =1 3 FAR 29 FAR Total First and Second Floor FAR 25 +13 =38 FAR 1 1 oo 1 1 4\ 15 .19 X0!0 of 03 04 .03 03 .03 08 .03 .14 .03 .03 1 1 1 1 1 1 1 -1/2 1 2 1 1 15 .19 27 .20 25 .22 36 .32 .33 .19 .28 03 04 .03 03 .03 08 .03 .14 .03 .03 03 18 .22 31 .23 28 .25 44 .35 .47 .22 .32 18 to .47 FAR 29 FAR 1 * STANDARDS FOR NON - CONTRIBUTING BUILDINGS IN HISTORIC DISTRICTS Standards for non - contributing buildings are intended to preserve the visual character of the historic district as a whole.

Vinyl windows are inappropriate for use on non - contributing buildings. Typical non - contributing residence in Old Towne 49 7. The use of elaborate architectural details or ornamentation that is not compatible with the building's predominant architectural style or surrounding contributing buildings should be avoided. 50 8. Additions to non - contributing buildings should be compatible with the mass, scale and setbacks of the existing building and surrounding historic properties. a. Generally, an addition should be no larger than the existing width and height of the non- contributing building and should not exceed the dimensions of surrounding historic properties. b. The prevailing pattern of setbacks on the street should b4 retained. c. Simple roof forms that reflect the form of the non- contributing building and surrounding historic buildings are appropriate. d. Second story additions to a one -story structure are discouraged. If proposed, a second story addition shall not cause a loss of privacy for surrounding properties and shall be compatible with the size, mass, and scale of properties on the same street. e. Conversion of attic space to habitable area within the existing roofline is encouraged. A half story addition may be appropriate, provided that the scale, size, and roof form are compatible with the 0 APPENDIX A GLOSSARY ACCESSORY STRUCTURE — A building or structure that is on the same lot and customarily incidental and subordinate to the principal building.
