per acre per year to gallons per square foot per year. The
c-on.vensanon factor is calculated as follows :
(325, 850 gallons/43 , 560 square feet)/12 inches = (0 . 62)
325, 850 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, the city' s billing unit for water, divide gallons per year
by 748 . (748 gallons = 100 cubic feet. )

when established in the landscape, is able to grow and survive
on little or no additional water than is provided by rainfall .
(h) "ecological restoration project" means a project
where the site is intentionally altered to establish a defined,
indigenous, historic ecosystem.
(i) "effective precipitation" or "usable rainfall"
means the portion of total precipitation that is used by the
plants .
(j ) "emitter" means drip irrigation fittings or

This ET adjustment factor of 0 . 8 is an average.
It is determined by combining the total plant palate mix of a
project to determine the plant factor, in this case an average
of 0. 5, and dividing this by the irrigation efficiency, in this
case the minimum of 0 . 625 .
Therefore, the ET adjustment factor (0. 8) = plant
factor average (0. 5)/irrigation efficiency minimum (0. 625) .

having plants with similar water needs that are served by a
valve or set of valves with the same schedule. A hydrozone may
be irrigated or non-irrigated. For example, a naturalized area
planted with native vegetation that will not need supplemental
irrigation once established is a non-irrigated hydrozone.
(s) "infiltration rate" means the rate of water entry
into the soil expressed as a depth of water per unit of time
(inches per hour) .
M "irrigation efficiency" means the measurement of
the amount of water beneficially used divided by the amount of

(dd) "plant factor" means a factor that when multiplied
by reference evapotranspiration, estimates the amount of water
used by plants . For purposes of this ordinance, the average
plant factor of low water using plants ranges from 0 to 0 .3 , for
average water using plants the range is 0 .4 to 0 . 6, and for high
water using plants the range is 0 . 7 to 1 . 0 .

year) (43 inches per year in Huntington
Beach) I'
0 . 8 = ET adjustment factor
LA = Landscaped Area (square feet)
0 . 62 = Conversion factor (to gallons per square
foot)
(2) An example for calculations of the Maximum
Applied Water Allowance is :
Project Site: Landscaped area of 50, 000 sq. ft.
in Huntington Beach
MAWA = (ETo) ( . 8) (LA) ( . 62)
(43 inches) ( . 8) (50, 000 square feet)
( . 62)
Maximum Applied Water Allowance (for this example)
= 1, 066,400 gallons per year (or 1,426
hundred-cubic-feet per year: 1, 066,400 divided by
748 = 1425 . 7) .
(3) Portions of landscaped areas in public and
private projects such as parks, playgrounds,
sports fields, golf courses, or school yards
where turf provides a playing surface or
serves other recreational purposes may
require water in addition to the Maximum
Applied Water Allowance. A statement shall

(c) Estimated Total Water Use.
(1) 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

tion (inches per year)
PF= Plant Factor
HA= Hydrozone Area (square feet)
( . 62)= conversion factor
IE=(0 . 625) Irrigation Efficiency
(0 . 625 as a minimum)
(2) If the Estimated Total Water Use is greater
than the Estimated Applied Water Use due to
the precipitation being included as a source
of water, an Effective Precipitation
Disclosure Statement, as depicted in Section
14 . 52 . 100(b) , shall be included in the
Landscape Documentation Package.
