landscape not exceed a maximum water demand of 80 percent of its reference
evapotranspiration (ETo) or any lower percentage as may be required by State
legislation;
E. To eliminate water waste from overspray and/or runoff; and
F. To promote water conservation through public awareness.

needs that are served by a valve or set of valves with the same irrigation schedule. A
hydrozone may also be nonirrigated, for example, a naturalized area.
"Irrigation efficiency" means the measurement of the amount of water beneficially used
divided by the amount of water applied.
"Landscape coefficient" means the functional equivalent of a crop coefficient in
agriculture. When multiplied times ETo, it estimates the amount of water required to

indicated at the base or nozzle of a sprinkler.
"Overspray" means when sprinklers deliver water beyond the landscaped area, wetting
pavements, walks, structures, or other nonlandscaped areas.
"Plant factor" means a factor that, in combination with irrigation efficiency, when
multiplied by reference evapotranspiration, estimates the amount of water used by
plants.
"Percolation" means the movement of water through the soil.
"Potable water" means water which is meant for human consumption.
"Precipitation rate" means the rate at which water is applied, usually expressed in
inches per hour.
"Pressure compensation bubbler" means an irrigation emitter useful for watering trees
and shrubs with water basins; produces a reduced flow of water that bubbles on the

or year and is an estimate of the evapotranspiration of a large field of four- to seven-
inch tall, cool season turf that is well watered. Reference evapotranspiration is used as
the basis of determining the maximum allowable water budget so that regional
differences in climate can be accommodated.
"Rehabilitated landscape" means a significant replacement of established landscaping
and/or irrigation with a new landscaping and irrigation. For purposes of this chapter,
"significant" is defined as any replacement exceeding fifty percent of a landscaped area
and is at the discretion of the director of planning. Rehabilitated landscapes shall be

under mulch.
0. If the area proposed for development is improved and is not scheduled for
development within six months of the completion of the previous phase, it shall be
temporarily landscaped and irrigated for dust and soil erosion control, and shall not be
counted toward meeting the landscaped area requirements of the zoning district.

(i.e., shrubs, massing in-mulched areas) in instances where spray irrigation is not
necessary.
I. Irrigation systems shall be zoned according to plant water use, slope aspect, and
sun/shade microclimate. If low water use plants (that can also survive/flourish with
medium water application) are used within a medium water use hydrozone, they must
be counted as medium water use in the irrigation calculations.
J. The use of head check valves shall be included in irrigation systems as
applicable.
K. Pressure regulation shall be incorporated into all irrigation systems to prevent

Zones:
Zorte 18. Zone 18, located inland from the ocean, was tradiUOnally an
area of apdwt, peach, apple, and walnut omhards. Now it's mostly filled
with suburban communities. Zone 18 areas are usually found on hilltops
and in cold-air basins, where winter lows can range from 28°F ro 10°F.
While It's too hot, cold, and dry for fuchsias, you can grow many of the
hardier subtropicals here. -
>ne 79. A wanner version of Zone 18, Zone 19, with winter
mperetures that range from 27°F to 22°F, is located next to Zone 18. It
one of the Southern California areas famous for citrus groves. You can
ow macadamia nuts and avocados here, as wall as many tropical and
ibtropfcel plants. Zone 19 is also an inland-valley area, onty minimally
Feded by the ocean.
mes 18 and 19 are viewed as a pair, with the major diNeronce that 18
cooler. They are both more influenced by inlantl climate factors than
the ocean.
