Division 2. Department of Water Resources
Chapter 2.7. Model Water Efficient Landscape Ordinance
§ 490. 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 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 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
(7) encourage local agencies to designate the necessary authority that implements and enforces the
provisions of the Model Water Efficient Landscape Ordinance or its local landscape ordinance.

§ 492.4 Water Efficient Landscape Worksheet.
(a) A project applicant shall complete the Water Efficient Landscape Worksheet which contains two
sections (see sample worksheet in Appendix B):
(1) a hydrozone information table (see Appendix B, Section A) for the landscape project; and
(2) a water budget calculation (see Appendix B, Section B) for the landscape project. For the calculation
of the Maximum Applied Water Allowance and Estimated Total Water Use, a project applicant shall use
the ETo values from the Reference Evapotranspiration Table in Appendix A. For geographic areas not
covered in Appendix A, use data from other cities located nearby in the same reference
evapotranspiration zone, as found in the CIMIS Reference Evapotranspiration Zones Map, Department
of Water Resources, 1999.
(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.
(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)]
7
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 as listed in the Reference Evapotranspiration Table in
Appendix A.
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)
LA = Landscape Area including SLA (square feet)
0.3 = Additional Water Allowance for SLA
SLA = Special Landscape Area (square feet)
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) x A + SLA)

Where:
ETWU = Estimated Total Water Use per year (gallons)
ETo = Reference Evapotranspiration (inches)
PF = Plant Factor from WUCOLS (see Section 491)

(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.
*Plant Factor from WUCOLS
ETWU= (51.1) (0.62)( +0
0.71 j
= 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.
*Plant Factor from WUCOLS
ETWU = (51.1)(0.62)( 23,500 + 2,000)
0.71
= (31.68) (33,099 + 2,000)
= 1,11 1,936 gallons per year
9
Compare ETWU with MAWA. For this example:
MAWA = (51.1) (0.62) [(0.7 x 50,000) + (0.3 x 2,000)]
= 31.68 x [35,000 + 600]
= 31.68 x 35,600
= 1,127,808 gallons per year
The ETWU (1,111,936 gallons per year) is less than MAWA (1,127,808 gallons per year). For this
example, the water budget complies with the MAWA.

Note: Authority Cited: Section 65595, Government Code. Reference: Section 65596, Government Code.
§ 493.2 Water Waste Prevention.
(a) Local agencies shall prevent water waste resulting from inefficient landscape irrigation by
prohibiting runoff from leaving the target landscape due to low head drainage, overspray, or other
similar conditions where water flows onto adjacent property, non - irrigated areas, walks, roadways,
parking lots, or structures. Penalties for violation of these prohibitions shall be established locally.
(b) Restrictions regarding overspray and runoff may be modified if:
(1) the landscape area is adjacent to permeable surfacing and no runoff occurs; or
(2) the adjacent non - permeable surfaces are designed and constructed to drain entirely to landscaping.
Note: Authority cited: Section 65594, Government Code. Reference: Section 65596, Government Code.
§ 494. Effective Precipitation.
(a) A local agency may consider Effective Precipitation (25% of annual precipitation) in tracking water
use and may use the following equation to calculate Maximum Applied Water Allowance:
MAWA= (ETo - Eppt) (0.62) [(0.7 x LA) + (0.3 x SLA)].

Assembly Bill No. 1881
CHAPTER 559
An act to add Section 1353 8 to the Civil Code, to repeal and add
Article 10.8 (commencing with Section 65591) of Chapter 3 of Division 1
of Title 7 of the Government Code, to add Section 25401.9 to the Public
Resources Code, and to add Article 4.5 (commencing with Section 535) to
Chapter 8 of Division 1 of the Water Code, relating to water conservation.
[Approved by Governor September 28, 2006. Filed with
Secretary of State September 28, 2006.]
LEGISLATIVE COUNSEL'S DIGEST
AB 1881, Laird. Water conservation.
(1) Existing law, the Davis - Sterling Common Interest Development
Act, defines and regulates common interest developments, which include
community apartment projects, condominium projects, planned
developments, and stock cooperatives.
This bill would provide that the architectural guidelines of a common
interest development shall not prohibit or include conditions that have the
effect of prohibiting the use of low water -using plants as a group
(2) The Water Conservation in Landscaping Act requires the
Department of Water Resources to appoint an advisory task force to work
with the department to draft a model local water efficient landscape
ordinance that local agencies may adopt, requires the task force to submit
the ordinance to the department on or before May 1, 1991, and requires the
task force to cease to exist on the date the department adopts the model
ordinance or January 1, 1992, whichever occurs first. The act requires the
department, not later than January 1, 1992, to adopt a model local water
efficient landscape ordinance which each local agency may adopt. The act
makes the model local water efficient landscape ordinance adopted by the
department applicable within the jurisdiction of a local agency if that local
agency, by January 1, 1993, has not adopted a water efficient landscape
ordinance or has not adopted certain findings that the adoption of the
ordinance is unnecessary.
This bill would specify that the provision making the model ordinance
applicable to a local agency on and after January 1, 1993, does not apply
to chartered cities. The bill would require the department, to the extent
funds are appropriated, not later than January 1, 2009, by regulation, to
update the model ordinance in accordance with specified requirements.
The bill would require the department to prepare and submit to the
Legislature a prescribed report before the adoption of the updated model
ordinance. The bill would require a local agency, not later than January 1,
2010, to adopt the updated model ordinance or other water efficient
92
Ch. 559 — 2 —
landscape ordinance that is at least as effective in conserving water as the
updated model ordinance. The bill would make the updated model
ordinance applicable within the jurisdiction of a local agency, including a
chartered city, if, by January 1, 2010, the local agency has not adopted its
own water efficient landscape ordinance or the updated model ordinance.
The bill would require each local agency, not later than January 31, 2010,
to notify the department as to whether the local agency is subject to the
department's updated model ordinance and, if not, to submit to the
department a copy of the water efficient landscape ordinance adopted by
the local agency, among other documents. The bill would require the
department, to the extent funds are appropriated, not later than January 31,
2011, to prepare and submit a report to the Legislature relating to the
status of water efficient landscape ordinances adopted by local agencies.
By imposing requirements on local agencies in connection with the
adoption of water efficient landscape ordinances, the bill would impose a
state - mandated local program.
(3) Existing law requires the State Energy Resources Conservation and
Development Commission (Energy Commission), after one or more public
hearings, to take specified action to reduce the wasteful, uneconomic,
inefficient, or unnecessary consumption of energy. Existing law requires
the Energy Commission, by January 1, 2004, to amend specified
regulations to require that residential clothes washers manufactured on or
after January 1, 2007, be at least as water efficient as commercial clothes
washers, and to take certain other related action.
This bill would require the Energy Commission, in consultation with the
department, to adopt, to the extent funds are available, by regulation
performance standards and labeling requirements for landscape irrigation
equipment, including irrigation controllers, moisture sensors, emission
devices, and valves to reduce the wasteful, uneconomic, inefficient, or
unnecessary consumption of energy or water. The bill would require the
Energy Commission to adopt those requirements for landscape irrigation
controllers and moisture sensors by January 1, 2010, and, on and after
January 1, 2012, would prohibit the sale or installation of an irrigation
controller or moisture sensor for landscape use unless the controller or
sensor meets those adopted requirements. The bill would require the
Energy Commission, on or before January 1, 2010, to prepare and submit
to the Legislature a report that sets forth a proposed schedule for adopting
performance standards and labeling requirements for emission devices and
valves.
(4) Existing law generally requires an urban water supplier to install
water meters on all municipal and industrial service connections located
within its service area on or before January 1, 2025
This bill would require a water purveyor as defined, to require as a
condition of new retail water service on and after January 1, 2008, the
installation of separate water meters to measure the volume of water used
exclusively for landscape purposes. The bill would make this requirement
applicable to specified service connections.
92
— 3 — Ch. 559
(5) The California Constitution requires the state to reimburse local
agencies and school districts for certain costs mandated by the state.
Statutory provisions establish procedures for making that reimbursement.
This bill would provide that, if the Commission on State Mandates
determines that the bill contains costs mandated by the state,
reimbursement for those costs shall be made pursuant to these statutory
provisions.
The people of the State of California do enact as follows
SECTION 1 Section 1353.8 is added to the Civil Code, to read:
1353 8. The architectural guidelines of a common interest development
shall not prohibit or include conditions that have the effect of prohibiting

model water efficient landscape ordinance adopted by the department
pursuant to Chapter 1145 of the Statutes of 1990
(3) It is the intent of the Legislature that the department promote the use
of this updated model ordinance.
(h) Notwithstanding Article 13 (commencing with Section 65700), this
article addresses a matter that is of statewide concern and is not a
municipal affair as that term is used in Section 5 of Article XI of the
California Constitution. Accordingly, it is the intent of the Legislature that
this article, except as provided in Section 65594, apply to all cities and
counties, including charter cities and charter counties.
65594. (a) Except as provided in Section 65595, if by January 1, 1993,
a local agency did not adopt a water efficient landscape ordinance and did
not adopt findings based on climatic, geological, or topographical
conditions, or water availability that state that a water efficient landscape
ordinance is unnecessary, the model water efficient landscape ordinance
adopted by the department pursuant to Chapter 1145 of the Statutes of
1990 shall apply within the jurisdiction of the local agency as of that date,
shall be enforced by the local agency, and shall have the same force and
effect as if adopted by the local agency.
(b) Notwithstanding subdivision (b) of Section 65592, subdivision (a)
does not apply to chartered cities.
(c) This section shall apply only until the department updates the model
ordinance
65595. (a) (1) To the extent funds are appropriated, not later than
