15.56.010 Purpose.
A. The State Legislature has found:
1. That the waters of the state are of limited supply and are subject to ever increasing
demands;
2. That the continuation of California's economic prosperity is dependent on the
availability of adequate supplies of water for future uses;
3. That it is the policy of the State to promote the conservation and efficient use of
water and to prevent the waste of this valuable resource;
4. That landscapes are essential to the quality of life in California by providing areas
for active and passive recreation and as an enhancement to the environment by
cleaning air and water, preventing erosion, offering fire protection, and replacing
ecosystems lost to development; and
5. That landscape design, installation, maintenance and management can and should
be water efficient; and
6. That Section 2 of Article X of the California Constitution specifies that the right
to use water is limited to the amount reasonably required for the beneficial use to
be served and the right does not and shall not extend to waste or unreasonable
method of use.
B. Consistent with these legislative findings, the purpose of this 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 planning, designing, installing, maintaining and
managing water efficient landscapes in new construction and rehabilitated
projects;
3. Establish provisions for water management practices and water waste prevention
for existing landscapes;
4. Use water efficiently without waste by setting a Maximum Applied Water
Allowance as an upper limit for water use and reduce water use to the lowest
practical amount;
5. Promote the benefits of consistent landscape ordinances with neighboring local
and regional agencies;
6. Encourage local agencies and water purveyors to use economic incentives that
promote the efficient use of water, such as implementing a tiered-rate structure;
and

B. Water budget calculations shall adhere to the following requirements:
1. The plant factor used shall be from WUCOLS. The plant factor ranges from 0 to
0.3 for low water use plants, from 0.4 to 0.6 for moderate water use plants, and
from 0.7 to 1.0 for high water use plants;
2. All water features shall be included in the high water use hydrozone and
temporarily irrigated areas shall be included in the low water use hydrozone;
3. All Special Landscape Areas shall be identified and their water use calculated as
described below; and
4. ETAF for Special Landscape Areas shall not exceed 1.0.
C. Maximum Applied Water Allowance
The Maximum Applied Water Allowance shall be calculated using the equation:
MAWA= (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
The example calculations below are hypothetical to demonstrate proper use of the
equations and do not represent an existing and/or planned landscape project. The ETo
values used in these calculations are from the Reference Evapotranspiration Table in
Appendix A, for planning purposes only. For actual irrigation scheduling, automatic
irrigation controllers are required and shall use current reference evapotranspiration data,
such as from the California Irrigation Management Information System(CIMIS), other
equivalent data, or soil moisture sensor data.
1. Example MAWA calculation: a hypothetical landscape project in Fresno, CA
with an irrigated landscape area of 50,000 square feet without any Special
Landscape Area(SLA= 0, no edible plants, recreational areas, or use of recycled
water). To calculate MAWA, the annual reference evapotranspiration value for
Fresno is 51.1 inches.
MAWA=(ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAWA=Maximum Applied Water Allowance (gallons per year)
ETo =Reference Evapotranspiration(inches per year)
0.62 =Conversion Factor(to gallons)
0.7 =ET Adjustment Factor(ETAF)

MAWA=(51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 0):
= 1,108,870 gallons per year
To convert from gallons per year to hundred-cubic-feet per year:
= 1,108,870/748 = 1,482 hundred-cubic-feet per year
(100 cubic feet=748 gallons)
2. In this next hypothetical example, the landscape project in Fresno, CA has-the
same ETo value of 51.1 inches and a total landscape area of 50,000 square feet.
Within the 50,000 square foot project, there is now a 2,000 square foot area
planted with edible plants. This 2,000 square foot area is considered to be a
Special Landscape Area.
MAWA=(ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAWA=(51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 2,000 square
feet)]
=31.68 x [35,000+ 600] gallons per year
=31.68 x 35,600 gallons per year
=1,127,808 gallons per year or 1,508 hundred-cubic-feet per year
D. Estimated Total Water Use.
The Estimated Total Water Use shall be calculated using the equation below. The sum of
the Estimated Total Water Use calculated for all hydrozones shall not exceed MAWA.
ETWU = (ETo)(0.62)(P Ix A +SLA)
Where:
ETWU=Estimated Total Water Use per year(gallons)
ETo =Reference Evapotranspiration (inches)

1. Example ETWU calculation: landscape area is 50,000 square feet; plant water use
type,plant factor, and hydrozone area are shown in the table below. The ETo
value is 51.1 inches per year. There are no Special Landscape Areas (recreational
area, area permanently and solely dedicated to edible plants, and area irrigated
with recycled water) in this example.

Sum 24,700
*Plant Factor from WUCOLS
ETWU=(51.1)(0.62)/24,700+0

= 1,102,116 gallons per year
Compare ETWU with MAWA: For this example MAWA=(51.1) (0.62) [(0.7 x
50,000)+(0.3 x 0)] = 1,108,870 gallons per year. The ETWU(1,102,116 gallons
per year) is less than MAWA(1,108,870 gallons per year). In this example, the
water budget complies with the MAWA.
2. Example ETWU calculation: total landscape area is 50,000 square feet, 2,000
square feet of which is planted with edible plants. The edible plant area is
considered a Special Landscape Area(SLA). The reference evapotranspiration
value is 51.1 inches per year. The plant type,plant factor, and hydrozone area are
shown in the table below.
