A.
The
State Legislature has found that:
1.
The
limited supply of state waters are subject to ever increasing demands;
2.
California's
economic prosperity depends on adequate supplies of water;
3.
State
Policy promotes conservation and efficient use of water;
4.
Landscapes
provide recreation areas, clean the air and water, prevent erosion,
offer fire protection and replace ecosystems displaced by development;
and
5.
Landscape
design, installation and maintenance can and should be water efficient.
B.
Consistent
with the legislative findings, the purpose of this chapter 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.
(Ord. 488 § 1, 1992)
The words used in this chapter have the meaning set forth below:
means a value located under a sprinkler head to hold water
in the system so it minimizes drainage from the lower elevation sprinkler
heads.
means the depth of water applied to a given area, usually
measured in inches per hour.
means the portion of water supplied by the irrigation system
to the landscape.
means a set of reproducible drawings which show significant
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.
means a mechanical or solid state timer, capable of operating
valve stations to set the days and length of time of a water application.
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.
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:
|
(325,829 gallons/43,560 square feet)/12 inches = (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, another
common billing unit for water, divide gallons per year by 748. (748
gallons = 100 cubic feet.)
|
means a project where the site is intentionally altered to
establish a defined, indigenous, historic ecosystem.
means the portion of total precipitation that is used by
the plants. Precipitation is not a reliable source of water, but can
contribute to some degree toward the water needs of the landscape.
means drip irrigation fittings that deliver water slowly
from the system to the soil.
means the point at which plants in the landscape have developed
roots into the soil adjacent to the root ball.
means the first year after installing the plant in the landscape.
means the portion of the estimated total water use is derived
from applied water. The estimated applied water use shall not exceed
the maximum applied water allowance. The estimated applied water use
may be the sum of the water recommended through the irrigation schedule.
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.
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.
|
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 purposes of the ET adjustment factor is 0.625, therefore,
the ET adjustment factor (0.8) = (0.5/0.625).
|
means the quantity of water evaporated from adjacent soil
surfaces and transpired by plants during a specific time.
means the rate at which water flows through pipes and valves
(gallons per minute or cubic feet per second).
means a portion of the landscaped area having plants with
similar water needs that are served by a valve or set or 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.
means the rate of water entry into the soil expressed as
a depth of water per unit of time (inches per hour).
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 chapter is 0.625. Greater irrigation efficiency can be expected
from well designed and maintained systems.
means a process to perform site inspections, evaluate irrigation
systems and develop efficient irrigation schedules.
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.
means the water delivery pipeline that supplies water to
the emitters or sprinklers from the valve.
means the pressurized pipeline that delivers water from the
water source to the valve or outlet.
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. The estimated applied water use shall not
exceed the maximum applied water allowances.
means any surface mining operation with a reclamation plan
approved in accordance with the Surface Mining and Reclamation Act
of 1975.
means any material such as leaves, bark, straw or other materials
left loose and applied to the soil surface to reduce evaporation.
means the pressure at which a system of sprinklers is designed
to operate, usually indicated at the base of a sprinkler.
means the water which is delivered beyond the landscaped
area, wetting pavements, walks, structures or other non-landscaped
areas.
means a factor that when multiplied by reference evapotranspiration,
estimates the amount of water used by plants. For purposes of this
chapter, the average plant factor or 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.
means a system which automatically shuts off the irrigation
system when it rains.
means a set of reproducible drawings which show significant
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.
means areas of active play or recreation such as sports fields,
school yards, picnic grounds or other areas with intense foot traffic.
means treated or recycled waste water of a quality suitable
for nonpotable uses such as landscape irrigation; not intended for
human consumption.
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-inch 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.
means any re-landscaping project that requires a permit.
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.
means a device that measures the amount of water in the soil.
means the classification of soil based on the percentage
of sand, silt, and clay in the soil.
means a device which sprays water through a nozzle.
means the pipeline or municipal water supply pressure when
water is not flowing.
means an area served by one valve or by a set of valves that
operate simultaneously.
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. Bermudagrass,
kikuyugrass, seashore paspalum, St. Augustinegrass, zoysiagrass, and
buffalo grass are warm-season grasses.
means the portion of total precipitation that is used by
the plants. Precipitation is not a reliable source of water, but can
contribute to some degree toward the water needs of the landscape.
means a device used to control the flow of water in the irrigation
system.
means a one-page checklist and a narrative summary of the
project as shown in Exhibit "A" set out following this chapter.

|
MAWA
|
=
|
Max. applied water allowance (gallons per year)
|
|
