REQUEST: AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF
PALM DESERT, CALIFORNIA, AMENDING SECTION 24,
ENVIRONMENT AND CONSERVATION, CHAPTER 24.04,
WATER-EFFICIENT LANDSCAPE ORDINANCE IN ITS
ENTIRETY, AND REPEALING MUNICIPAL CODE SECTIONS
8.70.330 AND 12.08.010 IN THEIR ENTIRETY
SUBMITTED BY: Mark Greenwood, P.E., Director of Public Works
APPLICANT: City of Palm Desert
DATE: December 10, 2009
CONTENTS: Ordinance No. 1201 , Exhibit A attached
CVWD Ordinance 1302.1
Recommendation
Waive further reading and pass Ordinance No. 1201 to second reading
amending Palm Desert Municipal Code, Section 24, Chapter 24.04, as
described in Exhibit A, and repeal Palm Desert Municipal Code Sections
8.70.330 and 12.08.010 in their entirety.
Landscape Beautification Committee Recommendation
The City's proposed Water Efficient Landscape Ordinance (Proposed Ordinance) was
presented to the Landscape Beautification Committee at its meeting on October 21,
2009. After discussion, staff was directed to work with the Coachella Valley Water
District (CVWD) to integrate their new Water Efficient Landscape Ordinance (CVWD
Ordinance) into the City's Proposed Ordinance. Due to the short time remaining before
the City's Proposed Ordinance is required to be approved and sent to the State, the
Committee directed staff to move forward with the approval process and to keep the
Committee informed as to the progress.
Executive Summary
California Assembly Bill 1881 (AB 1881) enacted into law on September 28, 2008,
modifies and strengthens the Water Conservation in Landscaping Act of 1990; and

requires that all cities and counties adopt the California Department of Water
Resources' (DWR) updated model water efficient landscape ordinance (State Model
Ordinance), or a customized local ordinance that is at least as effective in conserving
water as the State Model Ordinance. By amending the City's existing Water Efficient
Landscape Ordinance (Chapter 24.04) (WELO) as recommended, the City will be
compliant with AB 1881. In addition, by approving staff's recommendation, nuisance
water conditions as addressed currently in the City's Municipal Code will be
consolidated and addressed in the proposed Ordinance.
Backqround
In California, about half of the urban water used is for landscape irrigation. Water waste
is common in landscapes that are poorly designed or not well maintained. Water waste
(from runoff, overspray, low head drainage, leaks and excessive amounts of applied
irrigation water in landscapes) is prohibited by Section 2, Article X, of the California
Constitution. The State Legislature adopted the Water Conservation in Landscaping Act
(California Government Code, Section 65591 et seq.) (the Act) in 1990 to improve state
water conservation efforts by reducing the waste associated with outdoor landscaping
irrigation. The Act required the DWR to develop a model water efficient landscape
ordinance more than a decade ago. That ordinance is now outdated and fails to reflect
contemporary technological developments.
AB 1881, enacted into law on September 28, 2008, modifies and strengthens the Act. A
key provision of AB 1881 requires the DWR to update the existing State Model
Ordinance, which then serves as a model ordinance for cities and counties to adopt
mandatory local landscape irrigation ordinances. All cities and counties must either adopt
the DWR's State Model Ordinance, or adopt a customized local water efficient landscape
ordinance that is at least as effective in conserving water as the updated State Model
Ordinance.
AB 1881 makes the updated State Model Ordinance automatically applicable within the
jurisdiction of each city and county that has not adopted its own water efficient landscape
ordinance or the updated State Model Ordinance by January 1, 2010. As such, it is in the
best interest of the City to amend its current WELO in order to ensure that it is adaptable,
suitable, and able to be better integrated into existing regulatory documents and
practices.
The Proposed Ordinance was prepared with the thought in mind of simplifying and
streamlining the State Model Ordinance while maintaining the requirement of being "at
least as effective as" the State Model Ordinance. The State Model Ordinance contains
33 pages of both policy issues and technical procedures. CVWD developed the CVWD
Ordinance for the region that can be modified to address specific local concerns while still
being as effective as the State Model Ordinance. The CVWD Ordinance provides
regional consistency and is a more concise ordinance, which has been further

customized for the City to keep aesthetic (plant choice, spacing, and design) review and
approval process at the City level and shift the technical irrigation review and approval
process to CVW D.
The City's Proposed Ordinance
The Proposed Ordinance will establish water efficient landscape regulations that are as
efficient as the State Model Ordinance in saving water in compliance with AB 1881, and
provide more direct local control than the State Model Ordinance and the CVWD
Ordinance.
The Proposed Ordinance will amend the existing landscaping regulations in Chapter
24.04 entitled "Water Efficient Landscape of the PDMC," to reflect the State Model
Ordinance requirements. Forms to be submitted by project applicants related to the
Proposed Ordinance may be updated by the Planning Director, as appropriate, without
action by the City Council. _
Implementation of the Proposed Ordinance will be integrated into the existing
development review process. This streamlines the process for project applicants to the
fullest extent possible while ensuring that projects comply with the new regulations.
Applicability
The applicability criteria for the Proposed Ordinance are consistent with that required by
the State Model Ordinance. Projects that are subject to the requirements of the Proposed
Ordinance are identified as those that currently would require discretionary approval
and/or a ministerial permit and that meet certain size criteria.
Landscape projects that currently require discretionary approvals are generally associated
with new development projects and include a landscape plan. Two significant changes in
the Proposed Ordinance are the elimination of a minimum area exemption, and a
requirement for review of single family, homeowner driven landscape projects if the
landscape area is 5,000 square feet or greater.
Proposed Ordinance Regulations
The Proposed Ordinance reflects existing regulations in the City's current WELO, codifies
current standards and methodologies used in approving water efficient landscape plans,
and includes new standards required by the State Model Ordinance.
The City's Municipal Code currently covers nuisance water abatement in several locations
and the Proposed Ordinance consolidates these regulations.

Page4of5
Implementation
The Proposed Ordinance does not create a new development review process. Rather,
review and certification in compliance with the new regulations will be integrated into the
existing development review and plan check process.
Compliance with State Regulations
1. Justifications for Deviations from the State Model Ordinance
AB 1881 requires local agencies to include information in the record for any approval that
designates the locally-approved alternative to the State Model Ordinance as "equally
effective" in conserving landscaping irrigation water. The appropriate action is suggested
to utilize findings to establish the City's position in the record. In preparing the Proposed
Ordinance, no essential element of the State Model Ordinance has been dropped, only
re-organized to function more efficiently.
2. Reporting Requirement
AB 1881 requires each city and county to notify the DWR by January 31, 2010, as to
whether it is subject to the updated State Model Ordinance and, if not, to submit to the
DWR a copy of its local water efficient landscape ordinance, among other documents.
Additionally, the DWR is required, 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 cities and counties. Once the City
Council has adopted the Proposed Ordinance, staff will advise the DWR of its adoption.
Environmental Review
The Proposed Ordinance is exempt from review under the California Environmental
Quality Act (CEQA) (California Public Resources Code, Section 21000, et seq.).
Pursuant to State CEQA Guidelines, Section 15307 (14 Cal. Code Regs., § 15307), the
Proposed Ordinance is covered by the CEQA Categorical Exemption for actions taken to
assure the maintenance, restoration, enhancement, or protection of a natural resource
where the regulatory process involves procedures for protection of the environment. The
adoption of the Proposed Ordinance will result in the enhancement and protection of
water resources, and will not result in cumulative adverse environment impacts or any
other potentially significant impact described in State CEQA Guideline, Section 15300.2.

Fiscal Analysis
The changes in the WELO are not expected to cause any negative impact on the
General Fund. The approval process may result in less staff time due to CVWD's
involvement with the technical review component of the review process.

D. These provisions are supplementary and additional to the subdivision and zoning
regulation of this code and shall be read and construed as an integral part of the
regulations and controls established thereby. (Ord. 688 § 3, 1992)
24.04.020 — Definitions
The words used in Section 0.00.020 of the CVWD Ordinance have the meanings set
forth below.
ANTIDRAIN VALVE or CHECK VALVE - A valve located under/in a sprinkler head to
hold water in the system to eliminate drainage from the lower elevation sprinkler heads.
APPLICATION RATE - The depth of water applied to a given area, usually measured in
inches per hour and is also known as precipitation rate (sprinklers) or emission rate
(drippers/microsprayers) in gallons per hour.
APPLIED WATER - The portion of water supplied by the irrigation system to the
landscape.
AUTOMATIC CONTROLLER - Electronic or solid-state timer capable of operating valve
stations to set the days, time and length of time of a water application.
BACKFLOW PREVENTION DEVICE - A safety device used to prevent pollution or
contamination of the water supply due to the reverse flow of water from the irrigation
system.
BENEFICIAL USE - Water used for landscape evapotranspiration.
BILLING UNITS - Units of water (100 cubic feet = 1 billing unit = 748 gallons = 1 CCF)
for billing purposes. To convert gallons per year to 100 cubic feet per year, divide
gallons per year by 748. (748 gallons = 100 cubic feet).
CONVERSION FACTOR (0.62) — Is considered the number that converts the Maximum
Applied Water Allowance from acre-inches per acre to gallons per square foot. The
conversion factor is calculated as follows:
(325,851 gallons/43,560 square feet)/12 inches= (0.62)
325,851 gallons = one acre-foot
43,560 square feet = one acre
12 inches = one foot
DESERT LANDSCAPE - A desert landscape using native plants spaced to look like a
native habitat.

ORDINANCE NO. 1201
DISTRIBUTION UNIFORMITY — Is the measure of how evenly sprinklers apply water.
The low-quarter measurement method (DULQ) utilized in the irrigation audit procedure
is utilized for the purposes of these criteria. These criteria assume an attainable
performance level of 75% DULQ for spray heads, 80% DULQ for rotor heads and 85%
DULQ for recreational turf grass rotor heads.
DISTRICT —The Coachella Valley Water District.
DRIP IRRIGATION - A method of irrigation where the water is applied slowly at the
base of plants without watering the open space between plants.
ECOLOGICAL RESTORATION PROJECT — Is a project where the site is intentionally
altered to establish a defined, indigenous, historic ecosystem.
EFFECTIVE PRECIPITATION or USABLE RAINFALL - The portion of total natural
precipitation that is used by the plants, usually assumed to be three inches annually.
Precipitation or rainfall is not considered a reliable source of water in the desert.
ELECTRONIC CONTROLLERS — Are time clocks that have the capabilities of
multiprogramming, water budgeting and multiple start times.
EMISSION UNIFORMITY — Is the measure of how evenly drip and microspray emitters
apply water. The low-quarter measurement method (EULQ) utilized in the landscape
irrigation evaluation procedure is utilized for the purposes of these criteria. These
criteria assume 90% EULQ for drippers, microsprays and pressure compensating
bubblers.
EMITTER - Drip irrigation fittings that deliver water slowly from the watering system to
the soil.
ESTABLISHED LANDSCAPE - The point at which new plants in the landscape have
developed roots into the soil adjacent to the root ball.
ESTABLISHMENT PERIOD — Is the first year after installing the plant in the landscape.
ESTIMATED TOTAL WATER USE (By hydrozone) - The portion of the estimated
annual total applied water use that is derived from applied water to a specified
hydrozone.
ESTIMATED ANNUAL TOTAL APPLIED WATER USE (Total of all hydrozones) - The
annual total amount of water estimated to be needed by all hydrozones to keep the
plants and water features in the landscaped area healthy and visually pleasing. It is
based upon such factors as the local evapotranspiration rate, the size of the landscaped
area, the size and type of water feature, the types of plants, and the efficiency of the
irrigation system. The estimated annual total applied water use shall not exceed the
Maximum Applied Water Allowance (MAWA).

surfaces and transpired by plants expressed in inches during a specific time.
ET ADJUSTMENT FACTOR - A factor of 0.5 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 0.38 is the basis of the plant factor portion
of this calculation. The irrigation efficiency for purposes of the ET adjustment factor is
0.75. Therefore, the ET adjustment factor (0.5) _ (0.38/0.75).
FINISHED GRADE — Grade height after surface mulch covering has been installed.
FLOW RATE - The rate at which water flows through pipes, valves and meters (gallons
per minute or cubic feet per second).

of water if the spray head is broken or missing.
HYDROZONE — Is the portion of the landscaped area 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.
INFILTRATION RATE - The rate of water entry into the soil expressed as a depth of
water per unit of time (inches per hour).

through the air to large irrigated areas.
OVERSPRAY - The water which is delivered beyond the landscaped area onto
pavements, walks, structures or other non-landscape areas. Also known as hardscape
applications.
PLANT FACTOR - A factor that, when multiplied by reference evapotranspiration,
estimates the amount of water used by plants. For purposes of these criteria, the
average plant factor of very low water using plants ranges from 0.01 to 0.10, for low
water using plants the range is 0.10 to 0.30, for moderate water using plants the range
is 0.40 to 0.60, and for high water using plants, the range is 0.70 to 0.90. Reference:
Water Use Classifications of Landscape Species III (WUCOLS III).

RECREATIONAL TURF GRASS - High traffic turf grass that serves as a playing surface
for sports and recreational activities. Athletic fields, golf courses, parks and school
playgrounds are all examples of areas having recreational turf grass.
8
ORDINANCE NO. �L
RECREATIONAL TURF GRASS ET ADJUSTMENT FACTOR - A factor of 0.82 that,
when applied to reference evapotranspiration, adjusts for the additional stress of high
traffic on recreational turf grass and the higher irrigation efficiencies of long-range rotary
sprinklers. These are the two major influences upon the amount of water that needs to
be applied to a recreational landscape. A mixed cool/warm season turf grass with a
seasonal average of 0.7 is the basis of the plant factor portion of this calculation. The
irrigation efficiency of long-range sprinklers for purposes of the ET adjustment factor is
0.85. Therefore, the ET adjustment factor is 0.82 = 0.7/0.85.
REFERENCE EVAPOTRANSPIRATION or ETo - A standard measurement of the
environmental parameters which affect the water use of plants, using cool season grass
as a reference. ETo is expressed in inches per day, month or year and is an estimate
of the evapotranspiration of a large field of cool-season grass that is well watered.
Reference evapotranspiration is used as a basis of determining the Maximum Applied
Water Allowances so that regional differences in climate can be accommodated. For
purposes of these criteria, CVWD Drawing No. 29523 will be used for ETo zones.
REHABILITATED LANDSCAPE - Any re-landscaping project in which the choice of new
plant material and/or new irrigation system components is such that the calculation of
the site's estimated water use will be significantly changed. The new estimated water
use calculation must not exceed the Maximum Applied Water Allowance (MAWA)
calculated for the site using a 0.5 ET adjustment factor.
RIPARIAN PLANTS - Riparian plants are high water using and water-loving plants that
are found growing naturally along flowing rivers and lake shores. They may also be
native to wet swampy areas with high water tables or poor drainage.
RUNOFF - Irrigation water which is not absorbed by the soil or landscape to which it is
applied and which flows from the planted area.
SERVICE LINE — Is the pressurized pipeline that delivers water from the water source
to the water meter.
SMART CONTROLLER — Weather-based or soil moisture-based irrigation controls that
monitor and use information about environmental conditions for a specific location and
landscape (such as soil moisture, rain, wind, the plants' evaporation and transpiration
rates and, in some cases, plant type and more) to automatically control when to water
and when not to, providing exactly the right amount of water to maintain lush, healthy
growing conditions.
SOIL MOISTURE-SENSING DEVICE — Is a device that measures the amount of water
in the soil.
SOIL TEXTURE - The classification of soil based on the percentage of sand, silt and
clay in the soil.

a. The landscape design must be carefully planned and take into
account the intended function of the project.
b. Plants' appropriateness shall be selected based upon their
adaptability to the climatic, geologic and topographical conditions
of the site.
c. Selection of water-efficient and low-maintenance plant material is
required.
d. All planted areas must be a minimum of one inch below adjacent
hardscapes to eliminate runoff and overflow.
14
i
e. Long, narrow or irregularly shaped turf areas shall not be designed
because of the difficulty in irrigating uniformly without overspray
onto hardscaped areas, streets and sidewalks. Areas less than 8
feet in width shall not be designed with turf. Turf will be allowed
in these areas only if irrigation design reflects the use of subsurface
irrigation or a surface flow/wick irrigation system.
£ Turf areas irrigated with spray/rotor systems must be set back at
least 24 inches from curbs, driveways, sidewalks or any other area
that may result in runoff of water onto streets. An undulating
landscape buffer area created by the setback shall be designed with
rocks, cobble or decomposed granite and/or can be landscaped
with drip irrigated shrubs/aec��ts or covered with a suitable
ground cover.
g. Plants having simila���vater use shall be grouped together in
distinct hydrozones,
��,
h. The use of a soil covering mulch or a mineral groundcover of a
minimum two-inch d�pth to red��� soil surface°evaparation is
required around trees, shrubs and'on nonirrigated a�'eas. The use of
bould�r� and cobble shall tie considered to reduce the total
vegetat'ion a�`ea.
i. Annual color plantings s�iall be used.only in areas of high visual
� �irnpact close��,where p�"�1e,can ap����ciate them. Otherwise, drip
`' ' ' �irriga�ed,perennial plantings sl�auld be the primary source of
`�, color::�
� ,� �
j� Native desert plants'shall be specified to be planted in a shallow,
vt�ide,'roug��ole two,times the root ball width. The root ball will
� °'��-��; - �i��s�t on eit�i�ra ur�iisturtied native soil or a firmed native soil. The
root ball top will be s�t even with the finished surface grade or
above grade if the soil is poorly drained. The hole must be
backfilled v��,th native soil. Extra soil may be used to mound up
around plants'where the soil is poorly drained.
k. Landscaping must not obstruct or interfere with street signs, lights
or road/walkway visibility. Screening may be provided by walls,
' berms or plantings.
1. ' Use locally approved plant materials lists in the selection of
appropriate plants.
m. Planter islands in parking lots with canopy trees shall be sized to
meet local land use agency requirements.
n. A landscape plan in fire-prone areas shall address fire safety and
prevention. A defensible space or zone around a building or
structure is required per Public Resources Code Section 4291 (a)
and (b). Avoid fire-prone plant material and highly flammable
mulches.

which includes community apartment projects, condominiums,
planned developments and stock cooperatives, shall not prohibit or
include conditions that have the effect of prohibiting the use of
low-water use plants as a group (California Civil Code, Section
1353.8).
D. Grading Design Plan
1. For efficient use of water, grading of a project site shall be designed to
minimize soil erosion, runoff and water vvaste. A grading plan shall be
submitted as part of the Landscape Dbcumentation Package. A
comprehensive grading plan prepa��;d by a civil engineer for other local
agency permits satisfies this re�uir�rii�nt.
y,,
2. The project applicant shal��subnlit a landscap�e grading plan that
indicates finished configur��ions and elevati+�i�s of the landscape area
including; 'r , �
�
a. Height of graded slci�i�s;
�;;
b. Drain�g�patterns;
�
c. Pad el�vatio:t�s;
�° �,
d. Finish gracl�, and ! � ' �
41
�. '�Stormwater�etention ii�a.pro�ement�; i�applicable.
� , �
3. r'�To prevent �xcessiv����osi€�n and rur�off, it is highly recommended, and
� L ' per local agency requireri�ents, that project applicants:
, :
a.� " Grad�so tl�at all irri�a,tion and normal rainfall remains within
pxc�perty lines and do�s�ot drain on to non-permeable hardscapes;
' b. Avoid disruption ofnatural drainage patterns and undisturbed soil;
and
c. `Avoid soil compaction in landscape areas.
, ��
E4. , The gradit�g design plan shall contain the following statement: "I have
complied.with the criteria of the ordinance and applied them accordingly
�or the.e�ficient use of water in the grading plan."
5. Tur�:is not allowed on slopes greater than 25% where the toe of the
slope�is adjacent to an impermeable hardscape and where 25%means 1
foot of vertical elevation change for every 4 feet of horizontal length
(rise divided by run x 100 = slope percent).
6. Slopes greater than 25% shall not be irrigated with an irrigation system
with a precipitation rate exceeding 0.75 inches per hour. This restriction
may be modified if the landscape designer specifies an alternative
design or technology, as part of the Landscape Documentation Package,
and clearly demonstrates no runoff or erosion will occur. Prevention of
runoff must be confirmed during an irrigation audit.
7. All grading must retain normal stormwater runoff and provide for an
area of containment. All irrigation water must be retained within
1�
i
property lines and not allowed to flow into public streets or public
rights-of-way. Where appropriate, a simulated dry creek bed may be
used to convey storm drainage into retention areas. A drywell shall be
installed if the retention basin is to be used as a recreational area.
8. Mounded or sloped planting areas that contribute to runoff onto
hardscape are prohibited. Sloped planting areas above a hardscaped
area shall be avoided unless there is a drainage swale at toe of slope to
direct runoff away from hardscape. .
9. Median islands must be graded to prev�nt stormwater and excess
irrigation runoff.

APPENDIX D
SAMPLE CALCULATION/ESTIMATED TOTAL WATER USE (bv Hvdrozone)
Using the following formula from Appendix C:
ETWU =(ETo) x (PF) x (LA) x (.62)] / (748) / (IE)
ETWU =Estimated Water Use (hundred cubic feet)
ETo =Reference Evapotranspiration(inches)
[for period of estimate]
PF =Plant Factor (Kc)
LA =Landscaped Area(in square feet)
.62 =Conversion Factor(to gallons per square foot)
748 =Conversion Factor(to hundred cubic feet)
IE =Irrigation System Efficiency
Project Site Example: Total landscaped area 60,000 square feet in Palm Desert near the
intersection of Cook Street and Country Club Drive in Zone No. 3
(75.0" Annual ETo).
• 16,500 square feet of turf grass overseeded with rye grass in winter, irrigated with low
angle rotor sprinklers.
• 28,200 square feet of"low" desert native plantings on drip irrigation.
• 15,300 square feet of"moderate"water using plantings on drip irrigation.
See Appendix C for formula factors. ETo is totaled for season. Turf grass plant factors are the
average for the season and tree/shrub/groundcover plant factors are considered constant annually.
Plant Factors
Turf Low Native Moderate
Grass Plants Shrubs
0.70 0.20 0.50
ETWU= [(ETo) x (PF) x (LA) x (.62)/ (748)] / (IE) = CCF
Overseeded Turf Grass: Season= 75.0 x .7 x 16,500 x .62 / 748 /.80 = 897 CCF
Seasonal Turf ETWLT= 897 CCF
"Low"Native Plants: Annual = 75.0 x .2 x 28,200 x .62 / 748 / .90 = 389 CCF
"Low"Native ETWLJ= 389 CCF
"Moderate" Shrubs and Ground Cover: Annual = 75.0 x .5 x 15,300 x .62 / 748 / .90 = 528 CCF
"Moderate" ETWU = 528 CCF
Project Total ETWU= 1,814 CCF
APPENDIX D
SAMPLE CALCULATION
Maximum A�plied Water Allowance (MAWA�
Using the following formula:
Mawa= ��ETo� X �o.so� X �La� X �0.62�� i ��4s�
MAWA=Maximum Applied Water Allowance (CCF or hundred cubic feet)
ETo =Reference Evapotranspiration (inches per year)
0.50 =ET adjustment factor= .38 PF/ .75 IE
LA = Landscaped Area(square feet)
0.62 = Conversion Factor(to gallons per square foot)
748 = Conversion Factor(to hundred cubic feet)
Using the project for the Estimated Total Water Use example:
Landscaped area of 60,000 square feet in Palm Desert near the intersection of Cook Street
and Country Club Drive in Zone No. 3 (75.0"Annual ETo).
MAWA =75.0 (ETo) x (0.50) x (LA)x (0.62) /(748)
_ [75.0(.50) (60,000) (0.62)] /(748)
MAWA = 1,864 CCF
ETWU total of 1,814 CCF is <the MAWA of 1,865 CCF

APPENDIX G
Recvcled Water Checklist
l. Obtain coverage under the general waste discharge requirements for discharge of
recycled water for golf course and landscape irrigation Order No. 97-700 or equivalent
version of this permit from the California Regional Water Quality Control Board of the
Colorado River Basin Region(Regional Board) by submitting a Notice of Intent to the
Regional Board and paying application/annual fees.
2., Enter into an agreement with CVWD for receiving nonpotable water for golf course and
landscape irrigation. The agreement between discharger and CVWD must be provided to
the Regional Board within 90 days of receiving coverage under the permit referenced
above in item#1.
3. Landscape and Irrigation system plans must meet regulatory requirements of Order 97-
700 or equivalent version of this permit, the State Board's Recycled Water Policy, and
California Department of Public Health (CDPH) Statutes and Regulations related to
recycled water, such as the Health and Safety Code, the Water Code, Title 17 and Title
22 Code of Regulations. These requirements include but are not limited to the following:
a. An air-gap separation, a vertically measured distance between supply pipe
and receiving vessel must be present and meet the required distance for the
size of the supply pipe.
b. The appropriate type of backflow protection is to be installed for auxiliary
water supplies and recycled water.
c. The required separation distance between recycled water lines and
impoundments and application area; and domestic wells and water lines is
maintained and approved by CDPH.
d. The design of the irrigation system shall not cause the occurrence of ponding
anywhere in the reuse area, and overspray or mist around dwellings, outdoor
eating areas and/or food handling facilities is eliminated. Irrigation runoff
shall be confined to the recycled water use area unless authorized by CDPH.
e. Drinking fountains will be protected from spray, mist or runoff by use of a
