Standards, and •
B) Water Waste Prohibition Ordinance.
1. EXECUTIVE SUMMARY:
The City of Petaluma Water Conservation Program for FY 2000/01 includes development and
implementation of a Landscape•Standard;and Water Waste Prohibition;.Ordinance that will reduce the
amount of water used by the customers of Petaluma's Water:Utility Systems. -
2. BACKGROUND:
The City of Petaluma's 2000/01 Water Conservation Program was approved by Petaluma City Council on July
17, 2000 and includes:
• Residential and Non-Residential.Toilet Replacement Program
• Residential Water Management Program
• Non-Residential Landscape Watt Audit and Incentive Program
• Landscape Water Conservation Ordinance and Water Waste Prohibition Ordinance
Commercial/Industrial Water Survey and Incentive Program
IP An estimated $2,780,083 of funding will be available from 1998 through 2009 to the City of Petaluma (City) for
water conservation measures and water reuse programs. These funds are,identified in Petaluma's portion of the
Sonoma County Water Agency's Draft Watt Conservation Plan with the goal to reduce water demands on the '
transmission system. SCWA staff will`be working closely with City staff to administer the water conservation
programs.
A) Landscape Water'Efficiency Standards of the City of Petaluma-,These Standards supercede the
Model Water Efficient Landscape Ordinance, as required by,California Assembly Bill325, 1992 (The
Water Conservation and Landscaping Act of 1990). Thepurpose of the Landscape Efficiency Standards
is to promote efficient water use and reduce water waste'through landscape and irrigation planning and •
design, installation,and long-term management specific to Petaluma's climate zone. The standard applies
to all new industrial, commercial, and institutional landscaping, multi-family common areas and
contractor installed single-family front yards in new sub-divisions (single-family residences and multi-
family private areas are exempt from these standards). Landscapes are designed and plants are selected
based on a design Water budget. The design water budget is-the upper limit of annual water use for the
established landscaped area supplied through City water'meters. The purpose of utilizing a design based
on a water budget is to create an'estimate of landscape water needs, thereby achieving water efficiency,
sound economic practices and landscape quality. Water efficiency can be,achieved by supplying only the
amount of water sufficient to meet plant needs. Applying only,thatamountof water needed by plants and
landscapes,,and avoiding„excess use, can save the customer.money. Identifying-and meeting water needs
can minimize the potential,for plant injury caused by water deficits or excess. Turf grass can be included
in a design,water budget, however;as turf grass has relatively:high.water needs, these standards do not
• permit turf on slopes and'in median strips, or tree planting in turf areas.
B) Water Waste Prohibition Ordinance-This water waste prohibition ordinance will modify the existing
Title 15 of the City of Petaluma Municipal code adding Chapter 15.12:071 Water.Waste Prohibitions.
The purpose of this Ordinance is to promote water conservation,and the efficient use of potable water
furnished by the City by eliminating;intentional or unintentional water waste when a reasonable
alternative solution is available, andby prohibiting use of equipment,whish is wasteful. The ordinance
identifies nonessential uses such as: the washing of sidewalks and other hard-surfaced areas by direct,
hosing not equipped with a shutoff nozzle;the escape of water through breaks or leaks; irrigation in a
manner or to the extent that allows excessive run=off of water; washing cars, boats, trailers or other.
vehicles and machinery directly with a hose not equipped with a shutoff nozzle; water for non-recycling
decorative water fountains; water for single pas evaporative cooling systems for air conditioning unless
required for health or safety,reasons;.water fornew non-recirculating,conveyor car wash systems; and •
water for new non-recirculating industrial clothes washsystems.
3. ALTERNATIVES:'
A) Continue operating/under the Model Water,EfficientbLandscape Ordinance,as required by California
Assembly Bill 325, 1992 (The Water Conservation and Landscaping Act of 1990).
B) Continue operating under the water waste.reduction:ordinance Title 15 of the City of Petaluma
Municipal code.
4. FINANCIAL IMPACTS:
A) Landscape Water Efficiency Standards of the City.of Petaluma will require landscape and irrigation plan
review for compliance either by in-house:staff or contract staff, The cost will be borne by the applicant.
B) Water Waste Reduction.Ordinance will increase in-house staff time responding to reports of water waste.
5. CONCLUSION:
'The City of-Petaluma should continue to implement;water conservation programs-in order to preserve
and protect existing water resources to improve•theslikelihood that additional water resources will be
available in the future and to helpdefer;capital costs for expansion of City,water_facilities..
6.. OUTCOMES;OR.PERFORMANCE-MEASUREMENTS THAT WILL.IDENTIFYSUCCESS OR:COMPLETION:
A) Adopt the resolution to approve the.Landscape Efficiency-Standards. ThezMontgomery Watson
1995 Study, Water'and Wastewater Efficiency/Avoided Cost Study, estimated that this water •
conservation measure would save 210 acre-feet of water per year in 20 years:
B)'Introduce and Adopt the Water Waste_Reduction,Ordinance. Water savings have not been estimated
for'this•water conservation measure.
7. RECOMMENDATION: •
A) Adopt the resolution approving Landscape Water Efficiency Standards of the;City of Petaluma and
Authorizing:the Director of:Water Resources and the Director of Parks and Recreation to Approve
Updates to the Standards, and •
B).. Introduce the Water Waste Prohibitions Ordinance at the May 7, 2001 meeting and adopt the ordinance
at.the May16,2001,meeting.

LANDSCAPE STANDARDS
I. PURPOSE
The purpose: of these standards is to promote efficient water use and reduce water Waste
•through landscape and irrigation planning and 'design, installation, and long-term landscape
managementspecific to Petalurria's'climate:zone.
•
•
All plants require water. Landscape irrigation, serves the purpose of maintaining a
healthy, attractive and functional landscape. A design:"water budget will'_match plant needs'to
water supply and maintain landscape.health and vigor: Applicants will develop 'a design water
. budget Per each.site;plan submitted for review.
The purpose of developing,a design water budget is to•create an estimate of landscape water
needs. Estimates of landscape water 'needs are 'important for at least three reasons water •
efficiency; economics; and landscape quality. Water efficiency can be•achieved •by.supplying
•
only the amount of water sufficient to meet plant needs. Applying only that amount cof water
needed by plants and landscapes, and avoiding excess use, can save the customer money.
Lastly, identifying and meeting plant water n eeds can minimize the potential for'plant injury.
caused by water deficits or excess.
' Turf grass can be included in :a design water .budget. Turf grass has relatively high water •
needs, therefore 1these standards do not permit turf grass on slopes.and in median strips : Tree
planting :in turf grass areas is not permitted (water supplied to meet turf needs is often. not
sufficient;fornewly planted trees in turf).
These Standards supersede ;the Model WaterEfficient;Landscape Ordinance, as required 'by
California.Assembly Bill 325, 1992 (The Water Conservation and Landscaping Act of 19904.
II.. APPLICATION
A. The standards apply to new industrial, commercial, and institutional landscaping,,,and'all,
new multi-family common areas and contractor installed single-family front yards in new
sub-divisions. •
B. Single=family residences and multi-family private areas are exempt from these
standards. However, all residents are encouraged;to follow thesestandards.
• C'. Schoolyards, parks;. playgrounds, sports fields, and golf courses are exempt from
establishing a design water budget. Every other requirement of these standards is
applicable,•including estimation of irrigation water requirements. In addition turf grass
areas of these ;sites shall have a landscape irrigation audit performed after the
installation or renovation of the irrigation system:
•

D The ;standards db nob.apply to ,cemeteries or registered, historical sites. However,
•,` landscape managers at these sites are rendbOraged to follow efficient irrigation system
management practices.
E. The staridards apply to any landscaping' that is irrigated ,solely by,reclaimed (treated,
recycled wastewater) water.. Reclaimed water may._contain' injurious levels of salts or
specific elements. When irrigating with reclaimed water, water quality will need to be
monitored'and assessed.. (Some upward adjustments°in water estimates may be needed
to.reducepJant.injurypotential With low quality water).
F. The standards do not apply torareas.devoted to agricultural cultivation.

490. Purpose. +
(a) The State Legislature has found:
(1) that the !limited supply of state waters are subject to ever
increasing demands;;
(2) that California's, economics prosperity depends on adequate
supplies of water;
(3) that state policy promotes conservation and efficient use
of water; -
(4) that landscapes. provide . recreation areas,, clean the air and
water, prevent erosion, offer fire protection, and replace
ecosystems displaced by development; and
• (5) that landscape; design, installation, and maintenance can
and should be, water efficient.;
(b) Consistent with the 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 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.

49.1 . Definitions.
The words used in this ordinance have the meaning set -forth below: .
(a) manti-drain valve" or "check valve" 'means a valve, located
Under a sprinkler head to hold water in the system so it minimizes
drainage 'from thei lower elevation* sprinkler -heads.
(b) "application rate" means the depth of water applied to a
given area susually measured in inches per hour.
(c) "applied water" means the portion of water supplied, by the
irrigation stern to the landScape. •
(0) "automatic controller" means ia mechanical or solid state:
timer, capable of operating, valve stations to set the days and length
of time of a water application.
(e) "hackflow prevention device" 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.
•
(f) "conversion factor (0.62)" 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 follovvS:
•
(325;851 gallons/ 43,560 square feet)/12 Inches = (0.62) • '
325•,851 gallons one acre foot
43560 square feet pne acre
• 12 inches One fobt
To *convert gallOns per year to 1,00.;otibic-feet per year, aridttfet
common billing unit for water, divide gallons per year by 748. (748
gallons = lop cubic feet.)
•
•
7
—
A combined plant mix with a site-wide average of 0.5 is the basis of
the lant factor
p 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).
(o). evapotranspiration q
means `the quantity of water evaporated
from adjacent soil. surfaces and transpired by plants during a
specific time.
•
(p) "flow rate" means the rate at .which water flows through
pipes and valves (gallons per minute or cubic feet per second).
(q) "hydrozone" means a 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.
•
(r) "infiltration rate" means the rate • of water entry into the soil
expressed as a depth of water pet unit of time (inches per hour).
(s) "irrigation efficiency" means the measurement of the
amount of water beneficially used divided by the amount of water
applied. Irrigation efficiency is derived from measurements and
Pp 9
estimates of irrigation system characteristics and management
practices. The minimum irrigation efficiency for purposes of this
ordinance is '0.625. Greater irrigation efficiency can be expected
from well designed and maintained systems.
(t) "landscape irrigation audit"' means a. process to perform
site inspections, evaluate irrigation systems, and develop efficient
irrigation schedules. •
•
•
• 9
(dd): "plant factor" means, a fact& that when multiplied by
reference evapotranspiration, estimates the amount of water used
•
by plants.. For'purposes of this ordinance, the average plant factor
of 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.
(ee) "rain sensing device" .means a system which automatically
shuts off the irrigation system When it rains.
(ff) "record 'drawing" or "as-builts" means a set of
reproducible drawings which 'show ,significant changes in the work
Made diking construction and which are -usually based on drawings
marked up in ;the field and other data furnished by the contractor.
(gg) "recreational area" means areas of active play or
recreation such as sports fields, school yards, picnic grounds, or
other areas With intense foot traffic. •
(hh) "recycled water," "reclaimed water," or "trpated
sewage effluent (water means treattd or recyolecc waste water
of a quality suitable for nonpotable uses such as landscape
irrigation; not intended for human consumption!
(ii) "reference evapotranspiration" or "Ejo" means a standard
measurement of environmental parameters which affect the water
use of plants. ETo,is given in inches per day, menth,. Or year as •
represented in Section 495, and is ant estimate of the
evapotranspiration of a large. field of four- to seven-inch tall, .thol-
season grass that is well watered. Reference evapoiranspiratiOn is
used as the basis of determining the Maximum Applied, Water •
Allowances so that regional differences in climate can be
accomModated.
(jj) "rehabilitated. landsCapem means any relandtcaping project
that requires a .permit.

(2) The Maximum Applied. Water Allowance
(A) A project's Maximum Applied Water Allowance shall be
calculate using the following formula:
MAWA = (ETo) (0.8) (LA) (0.62) where:
MAWA = Maximum Applied Water Allowance (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
0.8 = ET Adjustment Factor
LA = Landscaped. Area (square feet)
0.62 = conversion factor (to gallons per square foot)
(B) Two example calculations of the Maximum Applied Water
Allowance: are:
(i) PROJECT SITE ONE: Landscaped area of 50,00-0 sq, ft. irk, Fresno
MAWA = (ETo) (.8) (LA) (.62) •
= (51 inches) ( 8) (50,000 square feet) (.62)
Maximum Applied Water Allowance = 1 ,264,800 gallons per year
(or 1 ,691 hundred-cubic=feet per year: 1 ,264800/748=1 ,691 )
(ii) PFlOJECT SITE TWO: Landscaped area of 50,000 sq ft. in San
Francisco
MAWA = (ETo) (8) (LA) (.62)
= (35 'inches) (.8) (50,000 square feet) (.62)
Maximum Applied Water Allowance = 868,000 gallons per year
(or 1 1 60 hundred-Cubic-feet per year)
(C) Portions of landscaped areas in public and private projects' such
as parks, playgrounds, sports fields, golf courses, or school yards
where turf provides a playing surface or serves other recreational
purposes are considered• recreational areas and may require water in
addition to the Maximum Applied, Water Allowance. A statement
shall be included with the landscape design plan, designating
recreational' areas to be used for such purposes and specifying any
needed amount of additional water above the Maximum Applied Water
Allowance,.
• 18
(B) If the Estimated Total Water Use is greater than the
Estimated Applied Water Use due to precipitation being
included as a source of water, an Effective Precipitation
Disclosure, Statement such as the one in Section 494 shall be
included in the 'Landscape Documentation, Package.
(5). 'Landscape Design Plan
