LANDSCAPE WATER EFFICIENCY GUIDELINES
I. PURPOSE
The purpose of these guidelines is to assist the Applicants in designing and implementing
an efficient irrigation system and landscape in accordance with the City of Anaheim's
Landscape Water Efficiency Ordinance.
lI. APPLICABILITY
A. The guidelines shall apply to the following projects:
1. New and rehabilitated public, industrial, commercial and
institutional landscaping;
2. Commonly maintained, developer installed landscaping in single-
family and multi-family residential land uses;
3. Privately-owned landscapes that are under significant landscape
rehabilitation.
B. These guidelines shall not apply to the following exempt projects:
1. Homeowner installed landscapes on single family lots.
2. Cemeteries, school yards, parks, playgrounds, sports fields, theme
parks and golf courses;
3. Historical sites on the National Register of Historic Places;
4. Ecological restoration land uses that do not require a permanent
irrigation system;
5. Mined-land reclamation land uses that do not require a permanent
irrigation system;
6. Any project with a landscaped area less than 2,500 square feet.
7. Landscapes using reclaimed or recycled water that is approved and
appropriate for use.
8. Water features that are an integral element of a business operation
and are intended to generate revenue or educate the clientele of the
business. Exempt water features shall be on a separate water meter
from landscaped areas.
The Public Utilities Department or its designee shall will be the final authority in
defining the application of the ordinance and these guidelines.
III. DEFINITIONS
The terms in these Guidelines shall have the meaning set forth below:
Application rate means the depth of water applied to a given area, usually measured in
inches per hour.
Applied water means the portion of water supplied by the irrigation system to the
landscape.
Backflow prevention device means a safety device used to prevent pollution or
contamination of the potable water supply due to the reverse flow of water from the
irrigation system.
Certificate of Substantial Completion refers to the form to be submitted by the Applicant
at the completion of the project. It certifies that all plants and irrigation were installed as
specified by these guidelines.
Common area means those areas in a residential development maintained by either the
developer or a homeowners' association.
Conversion factor means a number that converts the maximum applied water allowance
from acre-inches per acre per year to gallons per square foot per year. The conversion
factor is 0.62 and is calculated as follows:
(325,829 gallons/43,560 square feet)/12 = 0.62
325,829 gallons = one acre foot
43,560 square feet = one acre
12 inches = one foot
To convert gallons per year to 100 cubic feet per year, divide the gallons per year by 748.
(748 gallons = 100 cubic feet.)
Ecological restoration means a project where the site is intentionally altered to re-
establish a defined, indigenous, historic ecosystem.
Established landscape means the point in time at which plants in the landscape have
developed roots into the soil adjacent to the root ball.
Establishment period means the first 18 months after installing the plant in the
landscape.
Estimated total water use means the annual total amount of water estimated to be
needed to keep the plants in the landscaped area healthy. It is based upon such factors
as the local evapotranspiration rate, the size of the landscaped area, the types of plants,
and the efficiency of the irrigation system, as described in Section "C".
ET adjustment factor means a factor of 0.8, that, when applied to reference
evapotranspiration, adjusts for plant factors and irrigation efficiency, two major influences
upon the amount of water that needs to be applied to the landscape. Further, a
combined plant mix with a site-wide average of 0.5 is the basis of the plant factor portion
of this calculation. The irrigation efficiency for the purposes of the ET adjustment factor
is 0.625. Therefore, the ET adjustment factor (0.8) = (0.5/0.625).
Evapotranspiration or ET means the quantity of water evaporated from adjacent soil
surfaces and transpired by plants during a specific time.
Flow rate means the rate at which water flows through pipes and valves (normally
expressed as gallons per minute, GPM, or cnbic feet per second).
Hydrozone means a portion of the landscaped area having plants with similar water needs
located in a similar microclimate that are served by a valve or set of valves. A hydrozone
may be irrigated or non-irrigated.
Infiltration rate means the rate of water entry/penetration into the soil expressed as a
depth of water per unit of time (inches per hour).
Irrigation efficiency means the measurement of the amount of water beneficially used
divided by the amount of water applied. Irrigation efficiency is derived from
measurements and estimates of irrigation system characteristics and management
practices. The minimum irrigation efficiency for purposes of these guidelines is 0.625
3
(62.5%). Greater irrigation efficiency can be expected from well designed and
maintained systems.
Landscape irrigation audit means a process to perform site inspections, evaluate
irrigation systems, and develop efficient irrigation schedules.
Eandscaped area means the entire parcel less the building footprint, driveways, non-
irrigated portions of parking lots, hardscapes such as decks and patios, and other non-
porous areas. Water features are included in the calculation of the landscaped area.
Areas dedicated to edible plants, such as orchards or vegetable gardens are not included.
Maximum Applied Water Allowance (MAWA) means, for design purposes, the upper
limit of annual applied water for the established landscaped area. It is based upon the
area's reference evapotranspiration, the ET adjustment factor, and the size of the
landscaped area.
Mined-land reclamation means any surface mining operation with a reclamation plan
approved in accordance with the Surface Mining and Reclamation Act of 1975.
Operating pressure means the pressure at which a system of irrigation heads is designed
to operate, usually indicated at the base of an irrigation head.
Overspray means the water which is delivered beyond the landscaped area, wetting
pavement, walks, structures, or other non-landscaped areas.
Plant factor means a factor that when multiplied by reference evapotranspiration,
estimates the amount of water used by plants. For purposes of these guidelines, the
plant factor of low water using plants is 0.3, for average water using plants the factor is
0.5, and for high water using plants the factor is 0.8. See the Water Use Classification
Of Landscape Species (WUCOLS) report, a project of the University of California
Cooperative Extension provided by the City in the Landscape Water Efficiency
Reference Package.
Project means the scheme or area of scheduled landscape construction activity.
Record drawings or as-bnilts means a set of reproducible drawings which show field
changes in the work made during construction and which are usually based on drawings
marked up in the field and other data furnished by the contractor.
Recreational area means areas of active play or recreation such as sports fields, school
yards, picnic grounds, or other areas with intense foot traffic.
4
Recycled water, reclaimed water. or treated sewage effluent water means treated or
:recycled waste water of a quality suitable for non-potable uses such as landscape
irrigation and 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 in inches per day, month,
or year, 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 so that regional differences in
climate can be accommodated. The City's ETo can be found in the reference
evapotranspiration document provided by the City in the Landscape Water Efficiency
Reference Package.
Run-off means water which is not absorbed by the soil or landscape to which it is applied
and flows from the area. For example, run-off may result from water that is applied at
too great a rate (application rate exceeds infiltration rate) or when there is a severe slope.
Static water pressure means the water pressure in the pipeline or municipal water supply
when the water is not flowing.
Significant landscape rehabilitation means any re-landscaping project that entails
alteration of fifty (50) percent or greater of the existing plant material (measured in
square footage), landscape design, or irrigation system, of projects of 2,500 square feet or
more.
Soil texture means the classification of soil based on the percentage of sand, silt, and clay
in the soil.
Sprinkler or irrigation head means a device which sprays water through a nozzle.
Station or Zone means an area served by one valve or by a set of valves.
Turf means a surface layer of earth containing mowed grass with its roots. Annual
Bluegrass, Kentucky Bluegrass, Perennial Ryegrass, Red Fescue, and Tall Fescue are
cool season grasses. Bermuda grass, Kikuyu grass, Seashore Paspalu, St. Augustine grass,
Zoysia grass, and Buffalo grass are warm-season grasses.
Valve means a device used to control the flow of water in the irrigation system.
Water conservation concept statement means a one-page check-list and a narrative of the
project as shown in these guidelines.

DESCRIPTION OF PROJECT: (Briefly describe the planning and design actions that are
intended to achieve conservation and efficiency in water use.)
Prepared By: Date:

B. MAXIMUM APPLIED WATER ALLOWANCE CALCULATIONS
A projeers Maximum Applied Water Allowance shall be calculated using the following
formula:
MAWA = (48) x (0.8) x (LA) x (0.62) = MAWA:
MAWA = Maximum Apolied Water Allowance (gallons per year)
48 = ETo Reference Evapotranspiration (inches per year)
0.8 = ET Adjustment Factor
LA = Landscaped Area (square feet)
0.62 = Conversion Factor (to gallons per square foot)
Two example calculations of the Maximum Applied Water Allowance are:
Example one:
PROJECT SITE ONE = Landscaped area of 50,000 sq. ft.
MAWA -- (Eto) x (.8) x (LA) x (.62) = MAWA
= (48 inches) x (.8) x (50,000 square feet) x (.62) = 1,190,400
Maximum Applied Water Allowance = 1,190,400 gallons per year (or 1,591 hundred-
cubic-feet per year: 1,190,400 / 748 = 1,591)
Example two:
PROJECT SITE TWO = Landscaped area of 3,000 sq. ft.
MAWA = (ETo) x (.8) x (LA) x (.62) = MAWA
= (48 inches) x (.8) x (3,000 square feet) x (.62) = 71,424
Maximum Applied Water Allowance = 71,424 gallons per year (or 95 hundred cubic
feet per year: 71,424 / 748 = 95)
C. ESTIMATED TOTAL WATER USE
A calculation of the estimated total water use shall be submitted with the Landscape
Documentation Package. The estimated total water use for the entire landscape area
equals the sum of the estimated water use of all hydrozones in the landscape area. The
estimated total water use shall be calculated by following the formula below:
EWU (hydrozone) = (48) (PF) (HA) (.62)
(62.5%)
EWU (hydrozone) = Estimated Water Use (gallons per year)
48 = ETo Reference Evapotranspiration (inches per year)
PF = Plant Factor (crop co-efficient)
HA = Hydrozone area (square feet)
.62 = Conversion Factor (to get gallons per
sq. ft. per year)
62.5% = A minimum Irrigation Efficiency
D. GRADING DESIGN PLAN
Grading design plans satisfying the following conditions shall be submitted with the
documents for landscape review:
1. A grading design plan shall be drawn on project base sheets on the same scale
as the planting plan. It should be separate from, but use the same format as,
