490. Purpose.
(a) The State Legislature. has found:
(1) that the limited supply of state waters are subject to ever
increasing demands;
(2) that California's economic prosperity depends on adequate
supplies of water;
(3) that state policy promotes conservation and efficient use
of water;
(4) that landsdapes provide recreation areas, clean the air and
water, prevent erosion, offer fire protection, and replace
ecosystems displaced by development; and
(5) that landscape design, installation, and maintenance can
and should be water efficient.
(b) Consistent with the legislative findings, the purpose of this
model ordinance is to:
(1) promote the values and benefits of landscapes while
recognizing the need to invest water and other resources as
efficiently as possible;
(2) establish a structure for designing, installing, and
maintaining water efficient landscapes in new projects; and
(3) establish
provisions
for
water management practices and
water waste
prevention
for
established landscapes.

F
491. Definitions..
The words used in this ordinance have the meaning set forth below:
(a) "anti -drain valve" or "check valve means a valve located
under a sprinkler head to hold water in the system so it minimizes
drainage from the lower elevation sprinkler heads.
(b) °'application rate" means the depth of water applied to a
given area, usually measured in inches per hour.
(c) "applied water" means the portion of water supplied by the
irrigation system to the landscape.
(d) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to set the days and length
of time of a water application.
(e) "backflow prevention device" means a safety device used to
prevent pollution or contamination of the water supply due to the
reverse flow of water from the irrigation system.
(f) "conversion factor (0.62)" 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
calculated as follows:
(325,851 gallons/ 43,560 square feet)/12 inches = (0.62)
325,851 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, another
common billing unit for water, divide gallons per year by 748. (748
gallons = 100 cubic feet.)
(g) "ecological restoration project" means a project where the
site is intentionally altered to establish a defined, indigenous,
historic ecosystem.
(h) "effective precipitation or "usable rainfall" means the

expressed as a depth of water per unit of time (inches per hour).
(s) "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 this

from well designed and maintained systems.
(t) "landscape irrigation audit" means a process to perf
orm
site inspections, evaluate irrigation systems, and develop efficient
irrigation schedules.

Description of Project
(Briefly describe the planning and design actions that are intended to
achieve conservation and efficiency in water use.)
Date: Prepared By:
16
(2) The Maximum Applied Water Allowance
(A) A project's Maximum Applied Water Allowance sha►I be
calculated using the following formula:
MAWA = (ETo) (0.8) (LA) (0.62) where:
MAWA =Maximum Applied Water Allowance (gallons per year)
TO = Reference Evapotranspiration (inches per year)
0.8 = ET Adjustment Factor
LA = Landscaped Area (square feet)
0.62 = conversion factor (to gallons per square foot)
(B) Two example calculations of the Maximum Applied Water
Allowance are:
(i) PROJECT SITE ONE: Landscaped area of 50,000 sq. ft. in Fresno
_ (51 inches) (.8) (50,000 square feet) (.62)
Maximum Applied Water Allowance = 1,264,800 gallons per year
(or 1,691 hundred -cubic -feet per year: 11264,800/748=11691)
(ii) PROJECT SITE TWO: Landscaped area of 50,000 sq. ft. in San
Francisco
MAWA = (ETo) (.8) (LA) (.62)
_ (35 inches) (.8) (50,000 square feet) (.62)
Maximum Applied Water Allowance = 868,000 gallons per year
(or. 1,160 hundred -cubic -feet per year)
(C) Portions of landscaped areas in public and private projects such
as parks, playgrounds, sports fields, golf cdursesI or school yards
where turf provides a playing surface or serves other recreational
purposes are considered recreational areas and may require water in
addition to the Maximum Applied Water Allowance. A statement
shall be included with the landscape design plan, designating
recreational areas to be used for such purposes and specifying any
needed amount of additional water above the Maximum Applied Water
Allowance.
17
(3) Estimated Applied Water Use
(A) The Estimated Applied Water Use shall not exceed the Maximum
Applied Water Allowance.
(B) A calculation of the Estimated Applied Water Use shall be
submitted with the Landscape Documentation Package. It may be
calculated by summing the amount of water recommended in the
irrigation schedule.
(4) Estimated Total Water Use.
(A) A calculation of the Estimated Total Water Use shall be
submitted with the Landscape Documentation Package. The
Estimated Total Water Use may be calculated by summing the
amount of water recommended in the irrigation schedule and adding
any amount of water expected from effective precipitation (not to
exceed 25 percent of the local annual mean precipitation) or may be
calculated from a formula such as the following:
The Estimated Total Water Use for the entire .landscaped area equals
the sum of the Estimated Water Use of all hydrozones in that
landscaped area.
EWU (hydrozone) _ (ETo) (PF) (HA) (.62)
(IE)
EWU (hydrozone) = Estimated Water Use (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
PF = plant factor
HA = hydrozone area (square feet)
(.62) = conversion factor
IE = irrigation efficiency
(B) If the Estimated Total Water Use is greater than the
Estimated Applied Water Use due to precipitation being
included as a source of water, an Effective <Precipitation
Disclosure Statement such as the one in Section 494 shall be
included in the Landscape Documentation Package..
(5) Landscape Design Plan
