A RESOLUTION OF THE CITY COUNCIL OF
THE CITY OF ORANGE AMENDING THE CITY
OF ORANGE LANDSCAPE STANDARDS AND
SPECIFICATIONS.
WHEREAS, Governor's Brown April 1, 2015 Drought Executive Order (B- 29 -25)
directed the California Department of Water Resources (DWR) to update the State's Model Water
Efficient Landscape Ordinance (MWELO) through an expedited regulation; and
WHEREAS, the State legislature has found that the waters of the State are of limited
supply and subject to ever increasing demands; and
WHEREAS, the continuation of California's economic prosperity is dependent on the
availability of adequate supplies of water for future uses; and
WHEREAS, it is the policy of the State to promote the conservation and efficient use of
water to prevent the waste of this valuable resource; and
WHEREAS, landscape design, installation, maintenance, and management can and should
be water efficient; and
WHEREAS, Article X, Section 2 of the California Constitution specifies that "waste or
unreasonable use ... of water be prevented" and that "the right to water is ... limited to such as shall
be reasonably required for the beneficial use to be served" and "such right does not and shall not
extend to the waste or unreasonable of use of water "; and
WHEREAS, Orange County has established a large reclaimed water infrastructure system;
and
WHEREAS, allocation -based water rate structures allow public agencies to document
water use in landscapes; and
WHEREAS, water use efficiency programs have been actively implemented within
Orange County since before 1991; and
WHEREAS, current local design practices in new landscapes typically achieve the State
Model Water Efficient Landscape Ordinance water use goals; and
WHEREAS, all water services within the City are metered; and
WHEREAS, all new irrigation controllers sold after 2012 within Orange County will be
smart controllers; and
WHEREAS, landscape plan submittal and review has been a long standing practice in the
City; and
WHEREAS, the average rainfall in Orange County is approximately 12 inches per year;
and
WHEREAS, the City, as the local water purveyor, has already enacted water waste
prohibitions for all existing metered landscaped areas within its jurisdiction; and
WHEREAS, consistent with these findings, the purpose of the City's Water Efficient
Landscape Section of the City's Landscape Standards and Specifications is to establish an
alternative to the State Model Water Efficient Landscape Ordinance that is acceptable under AB
1881 as being at least as effective as the State Model in the context of conditions in the City in
order to:
Promote the benefits of consistent landscape ordinances with neighboring local and
regional agencies.
Promote the values and benefits of landscapes while recognizing the need to invest
water and other resources efficiently.
Establish a structure for planning, designing, installing, maintaining and managing
water efficient landscapes in new construction and rehabilitation projects.
Establish provisions for water management practices and water waste prevention for
existing landscapes.
Use water efficiently by setting a Maximum Applied Water Allowance as an upper
limit for water use and reduce water use to the lowest practical amount.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Orange,
on the basis of the facts set forth in the agenda report presented to it and any testimony received at
the meeting at which this matter was considered, as follows:
1. The City Council finds and determines that the foregoing recitals are true and correct.
2. That the existing City of Orange Landscape Standards and Specifications are hereby repealed
in their entirety and replaced by City of Orange Landscape Standards and Specifications,
attached hereto as Exhibit "A ", which modifies the existing regulations and updates Section
IX, entitled "Water Efficient Landscapes," and Sub Section IX.1, "Guidelines for
Implementation."

I. INTRODUCTION
Landscaping is an important element in defining the image of any community. The City wishes to
promote quality landscape design and construction in order to maintain and enhance a positive
aesthetic image. To achieve this goal, these Landscape Standards and Specifications have been
prepared to establish standards for landscape design and construction and inspection of both private
and public works projects.
This document addresses all phases of landscape planning from conceptual design through
construction documentation. It is intended to serve as an easy -to -use manual, providing information
on plan preparation and processing, and containing regulations which will assure an acceptable level
of landscape treatment commonly encountered in the industry.
This manual further recognizes that large scale projects may address landscape planning in a
comprehensive manner through the Specific Plan process. In such instances, an exception to these
standards and specifications may be requested.
All installation of public works projects must follow the "Standard Specifications for Public Works
Construction" (Green Book). The standards and specifications of this manual do not supersede any
other applicable standards for public contracts. Where there are differences, the more stringent shall
apply. In addition, all landscape and irrigation designs shall be in compliance with the City of Orange
Landscape Standards and Specifications Section IX, Water Efficient Landscapes.
IMPORTANT
A complete set of landscape planning documentation will be made available
upon request. Other available documents include: Design Review Board
Requirements, Fuel Modification Requirements, Landscape Handout for
Product and Installation, Inspection Handout, and Standard Details and the
Water Efficient Landscape Guidelines for Implementation
NOTE: When conflicts exist within Sections of this document,
requirements within Section IX shall prevail.

LANDSCAPE STANDARDS AND SPECIFICATIONS
CITY OF ORANGE
Department of Community Services
LANDSCAPE PLAN SUBMITTAL
III. LANDSCAPE PLAN SUBMITTAL
III.1 GENERAL
Where landscaping is required as part of a private development or public works project, review
and approval of landscape and irrigation plans are required. All landscape design and
installation shall comply with provisions of this document.
Landscape plans will be considered in conjunction with overall project review. It is the intent
of the City to promote a comprehensive planning effort in which all design elements of a
project complement each other and are compatible with their surroundings. In addition,
landscape design must be suitable for the topography and coordinated with the preparation of
the site grading plan.
This section of the Landscape Standards and Specifications defines submittal and processing
requirements for landscape plan review and identifies the types of projects subject to landscape
review.
III.2 TYPES OF PROJECTS
Landscape plan review is required in conjunction with all development projects within the City
as follows:
Residential projects consisting of two or more units
Residential tracts
Commercial, industrial and institutional developments
Comprehensive developments (developments which provide an individualized plan
specifically for landscape planning)
Public Works projects
Refer to Section X.6, Water Efficient Landscapes, Chapter 1.2 of the Guidelines,
Applicability," for additional information.
The types of property within such projects which must be landscaped include, but are not
limited to:
Public rights -of -way and areas adjacent to public rights -of -way
Easements
Setbacks
Slopes
Open Space

III. 3 REVIEW PROCESS
III.3.1 Submittal
At such time as a development proposal is submitted to the City Department of
Community Development for review of site and building plans, a preliminary
landscape plan shall also be submitted. Landscape plans shall be reviewed
concurrently with the development plans as a component of the overall development
project.
Exception: Preliminary landscape plans are not required for project sites less than
10,000 square feet in size, when proposed development complies with all zoning
ordinance requirements and no discretionary Planning Commission or City Council
action is required. For these types of projects, planting and irrigation plans shall be
submitted to the Design Review Board prior to issuance of building permits.
Preliminary landscape plans shall contain enough information to illustrate the
landscape concept, but need not identify all the plant names and container sizes.
Landscape plans shall also include the Water Efficient Landscapes Specifications
information as stated in Chapters 1.2 and 2.0., Submittal Requirements for New
Landscape Installations or Landscape Rehabilitations of the Water Efficient
Landscapes Guidelines for Implementation. Preliminary plans shall include a legend
describing the shape and size of proposed plants shown on the plan, such as "large
deciduous shade tree" (Example: Platanus racemosa, California Sycamore), or "small
flowering tree" (Example: Lagerstroemia indica, Crape Myrtle), or "low ground cover
shrubs" (Example: Myoporum pacificum, Myoporum). The plan should include cross -
sections of the site or elevations showing how the mature planting will look in relation
to the building and parking streets. Section 111.7 delineates required contents of
preliminary plans.
III.3.2 Preliminary Plan Review
Community Development staff will forward preliminary landscape plans to the
Department of Community Services Parks Division for review and comment.
Comments may take the form of recommendations and /or conditions to be referred
to the final reviewing /approval body. Any questions regarding landscape
requirements or procedures should be directed to Community Services staff.
III.3.3 Construction Documents
Once the overall development project, including preliminary landscape plans, is
approved by the final reviewing body (Design Review Board, Planning Commission
or City Council) the applicant shall prepare and submit landscape construction
documents incorporating all conditions of approval. See Section 111.8 for specific
information regarding construction document plan sheet requirements.
6
Construction document submittal shall include the following:
Approved preliminary landscape plan
Conditions of approval
Construction document blue lines
Specifications
Soil Agronomic Report
Requirements of the Water Efficient Landscapes Guidelines
Construction document package shall be submitted to Community Services
Department and may be submitted either concurrently with other plans for building
permit plan check, or subsequent to building permit issuance. Concurrent processing
is not required in order to allow for completion of structural plan check corrections
which may affect the final site plan, prior to preparation of landscape construction
documents.
Landscape construction plans are subject to review and approval by the Department
of Community Services and all landscape and irrigation installation is subject to
inspection and approval. Final building inspection, power release and occupancy
permit shall not occur prior to satisfactory completion of landscape as required by the
Department of Community Services.
III.4 LANDSCAPE PLAN PREPARATION
For public works projects, landscape plans shall be prepared under the direct supervision of a
Registered Landscape Architect (State of California). For large scale or complex private
development projects, the City recommends that plans be prepared by a licensed professional
landscape architect.
If a landscape project meets the criteria defined in Section IX.6, Chapter 1.2A, "Applicability,"
of the Water Efficient Landscapes Guidelines, the plans shall be prepared by a licensed
professional landscape architect.
For smaller or less complex projects, licensed landscape contractors or professional
nurserymen may also prepare the plans.
All landscape plans shall conform to City Standards and Specifications, and shall be consistent
with the City's Manual of Grading. In addition, public works projects must also comply with
the Standard Specifications for Public Works Projects. If plans are found to be incomplete
by the City, they shall be returned unchecked to the owner /agent for completion.

III.5 FEES
Fees will be paid in accordance with the Master Schedule of Fees and Charges as adopted by
the City Council and available from the Department of Community Development. Fees will
be assessed for Plan Check and Inspection Services based on staff time spent in review
and inspection.
III.6 NUMBER OF PLANS
The number of sets of preliminary landscape plans needed are dictated by the review process
required for the overall development project and will therefore vary with each development.
For example, projects requiring Design Review Board review and Planning Commission
approval will have a wider distribution than those requiring only Design Review Board
approval. Therefore, only the initial submittal requirements are listed below for preliminary
plans. Additional copies of plans will be requested by staff once plan review has commenced.
9
Preliminary landscape plans — 5 sets
Landscape construction documents — 3 sets
In addition, upon final City approval of landscape plans for public works projects, residential
tracts containing common interest open space areas or large scale private development
projects, applicants shall provide to the Department of Community Services one complete
record set of plans, including revisions, on signed mylar reproducibles, 30" x 42" in size.
III.7 CONTENT OF PRELIMINARY LANDSCAPE PLANS
Preliminary plans must be prepared for the entire project site including all phases of
development. For example, landscape plans associated with a tentative map shall address all
the common ownership areas within the boundaries of the map and shall not be submitted

FUEL MODIFICATION REQUIREMENTS
31
VI. FUEL MODIFICATION
VI.1 INTRODUCTION
A fuel modification zone shall be required at the interface of a proposed development that
abuts a required natural or native open space area. The combination of slopes, accumulations
of flammable vegetation, hot, and climate (Santa Ana Winds), erodible soils and the intrusion
of urban activity creates the potential for loss of life, property and natural resources along the
wildland urban interface fire. A fuel modification program is used to implement an acceptable
and effective means to reduce the loss of life, property and natural resources from future
wildland fires. Through proper development criteria, land use alternatives, a comprehensive
fuel modification and management program, we can:
Reduce the numbers of uncontrolled fires
Reduce levels of risk
Reduce the intensity and spread of fires
Increase our ability to fight and control fires
Reduce erosion and flooding as a result of post fire rains
A fuel modification zone is a wide strip of land where flammable native vegetation is removed
and /or modified, and partially or totally replaced with permanent and /or temporarily irrigated,
drought - resistant, low -fuel or slow - burning plant materials.
Fuel modification requirements may vary depending upon the type and density of natural
vegetation at the project interface, topography, orientation or exposure to wind patterns, site
planning factors and construction type and design. Fuel modification concerns should be
analyzed early in the planning stages of a project so that requirements may be potentially
reduced through the utilization of single loaded streets, irrigated greenbelt layout, parks layout,
project sitting or other noncombustible uses as part of, or in lieu of, the fuel modification
zoning.

or damaged growth; 2.) to eliminate narrow V- shaped branch forks that lack strength;
3.) to reduce toppling and wind damage by thinning out crowns to maintain growth
within space limitations; 4.) to maintain a natural appearance; and, 5.) to balance crown
with roots.
Under no circumstances will stripping of lower branches (raising up) on young trees
be permitted. Retain lower branches in a tipped back or pinched condition with as
much foliage as possible to promote caliper trunk (tapered trunk). Lower branches
can be cut to the growth collar on the trunk only after the tree is able to stand erect
without staking or other support.
Thin out evergreen trees and shape when necessary to prevent wind and storm
damage. Do primary pruning of deciduous trees during dormant season. Prune
damaged trees or those that constitute health or safety hazards at any time during the
year as required.
VIII.5.7 Maintenance Operations for Shrubs
The objectives of shrub pruning are the same as for trees. Do not clip shrubs into
balled or boxed forms unless such is required by the design. Make pruning cuts to
lateral branches or buds. Pinch prune as necessary to encourage new growth and to
eliminate sucker growth. Old wilted flowers and dead foliage shall be pinched or cut
off.
VIII.5.8 Maintenance Operations for Ground Cover

The City may delegate to, or enter into a contract with, a local agency to implement, administer,
and /or enforce any of the provisions of the Water Efficient Landscape Section IX on behalf
of the City.
IX.5 Definitions
The following definitions are applicable to this [chapter /division /title]:
Aggregate landscape areas" pertains to the areas undergoing development as one project or for
production home neighborhoods or other situations where multiple parcels are undergoing
development as one project, but will eventually be individually owned.
Applied water" means the portion of water supplied by the irrigation system to the landscape.
Budget -based tiered -rate structure" means tiered or block rates for irrigation accounts charged by
the retail water agency in which the block definition for each customer is derived from lot size
or irrigated area and the evapotranspiration requirements of landscaping.
Community Aesthetics Evaluation" — While not subject to permit, plan check or design review,
the Community Aesthetics Evaluation may be performed to ensure the aesthetic standards of
the community and irrigation efficiency intent is maintained.
Ecological restoration project" means a project where the site is intentionally altered to establish a
defined, indigenous, historic ecosystem.
Estimated Applied Wlater Use" means the average annual total amount of water estimated to be
necessary to keep plants in a healthy state, calculated as provided in the Guidelines. It is based
on the reference evapotranspiration rate, the size of the landscape area, plant ivater use factors, and the
relative irrigation ciency of the irrigation system.
ET adjustmentfactor'' or "ETAF' is equal to the plantfactor divided by the irrigation fciencyfactor
for a landscape project as described in the Guidelines. The ETAF is calculated in the context of
local reference evapotranspiration using site - specific plant factors and irrigation fciency factors that
influence the amount of water that needs to be applied to the specific landscaped area.
A combined plant mix with a site -wide average plant factor of 0.5 (indicating a moderate water
need) and average irrigation 'kiency of 0.71 produces an ET adjustmentfactorof (0.7) _ (0.5/0.71),
which is the standard of water use efficiency generally required by this Water Efficient
Landscapes Section IX and the Guidelines, except that the ETAF for a special landscape area shall
not exceed 1.0.
Guidelines" refers to the Guidelines for Implementation of the Water Efficient Landscapes
Section IX of the City of Orange Landscape Standards and Specifications as adopted by the
City, which describes procedures, calculations and requirements for landscape projects subject to
this Water Efficient Landscapes Section IX.
Hardscapes" means any durable material or feature (pervious and non pervious) installed in or
around a landscaped area, such as pavements or walls. Pools and other water features are
considered part of the landscaped area and not considered bardscapes for purposes of this Water
Efficient Landscapes Section IX.
Irrigation fcieney" means the measurement of the amount of water beneficially used divided
by the amount of water applied. Irrigation fciencg is derived from measurements and estimates
of irrigation system characteristics and management practices. The irrigation efficiency for
purposes of this Water Efficient Landscapes Section IX are 0.75 for overhead spray devices
and 0.81 for drip systems.
Landscaped area" means all the planting areas, turf areas, and water features in a landscape design
plan subject to the Maximum Applied Dater Allowance and Estimated Applied Dater Use
calculations. The landscaped area does not include footprints of buildings or structures,
sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non -
pervious hardscapes, and other non - irrigated areas designated for non - development (e.g., open
spaces and existing native vegetation).
Landscape contractor" means a person licensed by the State of California to construct, maintain,
repair, install or subcontract the development of landscape systems.
Landscape Documentation Package" means the documents required to be provided to the City
for review and approval of landscape design projects as described in the Guidelines.
Landscape project" means total area of landscape in a project as provided in the definition of
landscaped area," meeting the requirements under Section IX.6 of this Water Efficient
Landscapes Section IX.
Local agency" means a city or county, including a charter city or charter county, that is
authorized to implement, administer and /or enforce any of the provisions of the Water
Efficient Landscapes Section IX. The local agency may be responsible for the enforcement or
delegation of enforcement of this Water Efficient Landscapes Section IX including, but not
limited to, design review, plan check, issuance of permits and inspection of a landscape project.
Local waterpurveyor" means any entity, including a public agency, city, county, or private water
company that provides retail water service.
Maximum Applied llaterAllowance" or "MAMA" means the upper limit of annual applied water
for the established landscaped area as specified in Section 2.2 of the Guidelines. It is based upon the
area's reference evapotranspiration, the ET Adjustment Factor and the size of the landscaped area. The
Estimated Applied rater Use shall not exceed the Maximum Applied VaterAllowance. MAWA =
ETo) (0.62) [(ETAF x LA) + ((1 -ETAF) x SLA)]
Mined -land reclamation projects" means any surface mining operation with a reclamation plan
approved in accordance with the Surface Mining and Reclamation Act of 1975.
New construction" means, for the purposes of this Water Efficient Landscapes Section IX, a
new building with a landscape or other new landscape such as a park, playground or greenbelt
without an associated building.
Non pervious" means any surface or natural material that does not allow for the passage of
water through the material and into the underlying soil.
Pervious" means any surface or material that allows the passage of water through the material
and into the underlying soil.
Permit" means an authorizing document issued by local agencies for new construction or
rehabilitated landscape.
Plant factor' or "plant mater use factor" is a factor, when multiplied by ETo, that estimates the
amount of water needed by plants. For purposes of this Water Efficient Landscapes Section
IX, the plant factor range for very low water use plants is 0 to 0.1; the plant factor range for low
water use plants is 0 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6;
and the plant factor range for high water use plants is 0.7 to 1.0. Plant factors cited in this Water
Efficient Landscapes Section IX are derived from the publication "Water Use Classification
of Landscape Species." Plant factors may also be obtained from horticultural researchers from
academic institutions or professional associations as approved by the California Department
of Water Resources (DWR).
Recycled water" or "reclaimed water" means treated or recycled waste water of a quality suitable
for non - potable uses such as landscape irrigation and water features. This water is not intended
for human consumption.
Reference evapotranspiration" or "ETo" means a standard measurement of environmental
parameters which affect the water use of plants. ETo is given expressed in inches per day,
month or year as represented in Appendix A of the Guidelines, and is an estimate of the
evapotranspiration of a large field of four -to seven -inch tall, cool - season grass that is well
watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied
Water Allowances.
Rehabilitated landscape" means any re- landscaping project that meets the applicability criteria of
Section 1.1(a) of the Guidelines, where the modified landscape area is greater than 2,500 square
feet.
Smart automatic irrigation controller" means an automatic timing device used to remotely control
valves that operate an irrigation system and which schedules irrigation events using either
evapotranspiration (weather- based) or soil moisture data.
Special landscape area" means an area of the landscape dedicated solely to edible plants, such as
orchards and vegetable gardens, areas irrigated with recycled water, waterfeatures using recycled water,
and recreational areas dedicated to active play, such as parks, sports fields, golf courses and
where turf provides a playing surface.
Turf' means a ground cover surface of mowed grass. Annual bluegrass, Kentucky bluegrass,
Perennial ryegrass, Red fescue, and Tall fescue are cool- season grasses. Bermuda grass, Kikuyu
grass, Seashore Paspalum, St. Augustine grass, Zoysia grass and Buffalo grass are warm - season
grasses.
Valve" means a device used to control the flow of water in an irrigation system.
Waterfeature" means a design element where open water performs an aesthetic or recreational
function. Dater features include ponds, lakes, waterfalls, fountains, artificial streams, spas and
swimming pools (where water is artificially supplied). The surface area of water features is
included in the high water use hydro .Zone of the landscaped area. Constructed wetlands used for
on -site wastewater treatment, habitat protection or storm water best management practices
that are not irrigated and used solely for water treatment or storm water retention are not water
features and, therefore, are not subject to the water budget calculation.

square feet, requiring a building or landscape permit, plan check or design
review;
3) New or rehabilitated landscape projects with an aggregate landscape area
of 2,500 square feet or less may comply with the performance requirements
of this Section IX or conform to the prescriptive measures contained in
Appendix A;
4) New or rehabilitated projects using treated or untreated graywater or
rainwater capture on site, any lot or parcels within the project that has less

2.2 Water Efficient Landscapes Calculations and Alternatives
a) The project applicant shall provide the calculated Maximum Applied Water
Allowance (MA WA) and Estimated Applied Water Use (EAWU) for the landscaped
area as part of the Landscape Documentation Package submittal to the City. The
MAWA and EAWU shall be calculated based on completing the Water Efficient
Landscapes Worksheets (in accordance with the sample worksheets in Appendix
4
C) which contain information on the plan factor, irrigation method, irrigation
efficiency and area associated with each hydrozone. Calculations are then made to
show that the evapotranspiration adjustment factor (ETAF) for the landscape
project does not exceed a factor of 0.55 for residential areas and 0.45 for non-
residential areas, exclusive of Special Landscape Areas. The ETAF for a landscape
project is based on the plant factor and irrigation methods selected. The Maximum
Applied Water Allowance is calculated based on the maximum ETAF allowed (0.55
for residential areas and 0.45 for non - residential areas) and expressed as annual
gallons required. The EAWU is calculated based on the plants used and irrigation
method selected for the landscape design.
b) The EAWU allowable for the landscaped area shall not exceed the MAWA. The
MAWA shall be calculated using an evapotranspiration adjustment factor (ETAF)
of 0.55 for residential areas and 0.45 for non - residential areas, except for the portion
of the MAWA applicable to any special landscaped areas within the landscape
project, which shall be calculated using an ETAF of 1.0. Where the design of the
landscaped area can otherwise be shown to be equivalently water - efficient, the
project applicant may submit alternative or abbreviated information supporting the
demonstration that the annual EAWU is less than the MAWA, at the discretion of
and for the review and approval of the local agency.
c) Water budget calculations shall adhere to the following requirements:
1) The MAWA shall be calculated using the Water Efficient Landscapes
Worksheets and equation presented in Appendix B on page B -1. The
example calculation on page B -1 is a hypothetical example to demonstrate
proper use of the equation.
2) The EAWU shall be calculated using the Water Efficient Landscapes
Worksheets and equation presented in Appendix C.
3) For the calculation of the MAWA and EAWU, a project applicant shall use
the ETo values from the closest location listed the Reference
Evapotranspiration Table in Appendix D. For geographic areas not
covered in Appendix D, data from other cities, or zip codes, located nearby
in the same reference evapotranspiration zone may be used.
4) For calculation of the EA WU, the plant water use factor shall be determined
as appropriate to the project location from the Water Use Efficiency of
Landscapes Species (WUCOLS) Species Evaluation List or from
horticultural researchers with academic institutions or professional
associations as approved by the California Department of Water Resources
DWR). The plant factor ranges from 0 to 0.1 for very low water use plants,
0. Ito 0.3 for low water use plants, 0.4 to 0.6 for moderate water use plants,
and 0.7 to 1.0 for high water use plants.
5
5) For calculating the EAWU, the plant water use factor shall be determined
for each valve hydrozone based on the highest- water -use plant species
within the zone. The plant factor for each hydrozone may be required to be
further refined as a "landscape coefficient" according to protocols defined
in detail in the WUCOLS document, to reflect planting density and
microclimate effects on water need at the option of the project applicant or
the City.
6) For calculation of the EAWU, the area of a water feature shall be defined as
a high water use hydrozone with a plant factor of 1.0.
7) For calculation of the EAWU, a temporarily irrigated hydrozone area, such
as an area of highly drought - tolerant native plants that are not intended to
be irrigated after they are fully established, shall be defined as a very low
water use hydrozone with a plant factor of 0.1.
8) For calculation of the MA WA, the ETAF for Special Landscape Areas (SLA)
shall be set at 1.0. For calculation of the EAWU, the ETAF for SLA shall
be calculated as the SLA plant factor divided by the SLA irrigation
efficiency factor.
9) Irrigation efficiency (IE) of the irrigation heads used within each hydrozone
shall be assumed to be as follows, unless otherwise indicated by the
irrigation equipment manufacturer's specifications or demonstrated by the
project applicant:
Irrigation Method DULQ DULH*EU IE **
Spray nozzles 65%79%71%
High efficiency spray nozzles 70%82%73%
Multi stream /Multi trajectory
rotary (MSMT) nozzles
75%85%76%
Stream rotor nozzle 70%82%73%
Microspray 75%85%76%
Bubblers 85%77%
Drip emitter 90%81%
Subsurface drip 90%81%
DULH = .386 + (.614)(DULQ)
IE (spray) _ (DULH)(IME)
IE (drip) = Emission uniformity (EU)(IME)
10)
d) The Maximum Applied Water Allowance shall adhere to the following
requirements:
1) The Maximum Applied Water Allowance shall be calculated using the
equation presented in Appendix C. The reference evapotranspiration
6
ETo) values used in this calculation are from the Reference
Evapotranspiration Table in Appendix D and are for planning purposes
