SUBJECT:
DWR LANDSCAPE
ORDINANCE
As you can tell from the enclosed "Notice of Proposed
Rulemaking" the State is determined that each community should have
a water efficient landscape ordinance. The time line i•s adoption by
January 1993.
The Utilities Committee has requested that this information
and a model ordinance be sent to you for your review and possible
comments by your respective Commissions. The sense that I have from
the Committee is that the detailed review is important but no final
determination is necessary until late 1992.
The hope is that we will have a good and bountiful rainy
season and the subject will be made made moot.
But just in case........

NOTICE OF PROPOSED RULEMAKING
NOTICE OF PROPOSED ADOPTION OF A MODEL WATER EFFICIENT LANDSCAPE
ORDINANCE TO IMPLEMENT THE WATER CONSERVATION IN LANDSCAPING ACT
NOTICE:
The Department of Water Resources (Department) proposes to adopt
the Model Water Efficient Landscape Ordinance (Model Ordinance)
to implement the Water Conservation in Landscaping Act, Statutes
of 1990, Chapter 1145, after considering all comments,
objections, or recommendations regarding the proposed action.
PROPOSED ACTION:
The Department proposes to adopt sections 700 through 704 in
Chapter 7, Division 2 of Title 23 of the California Code of
Regulations. These sections pertain to a Model Water Efficient
Landscape Ordinance that would apply to cities and counties that
have not adopted a water efficient landscape ordinance or that
have not adopted findings that such an ordinance is unnecessary.
PUBLIC HEARING:
The Department will conduct two public hearings on the proposed
Model Ordinance: one on October 2, 1991, at 9:00 a.m. in The
State Office Building, Room 1138, 107 South Broadway, Los
Angeles, California; and:a7iother on October 8, 1991, at 9:00 a.m.
in the Auditorium of the Resources Building, 1416 Ninth Street,
Sacramento, California. Any person wishing to make a statement
may do so at these hearings. The Department will receive both
oral and written staten.ants and comments. It is requested, but
not required, that persons making oral comments at the hearings
submit a written copy of their testimony at the hearings.
The hearing rooms at the Resources Building and The State office
Building are accessible to persons with mobility impairments.
The nearest off-street parking for the Resources Building is in
the garage at loth and "O" Streets.
WRITTEN COMMENT PERIOD:
Any interested person, or his or her authorized representative,
may submit to the Department their written comments relevant to
the proposed regulatory action.
1
Section,7'010 of the proposed Model Ordinance clarifies the
legislative intent and escribes the purpose of the ordinance.
The purpose of the Mod 1 Ordinance is to establish a structure
for designing, installing, and maintaining water efficient
landscapes. Section ,7.•2 defines terms used in the proposed Model
Ordinance. These definitions include technical terms that the
general public may find unfamiliar but are commonly used in
landscape design and terms that may appear common but have
specific meaning in the Model Ordinance.
Section99 describes the provisions of the Model Ordinance that
apply to new or rehabilitated landscapes. These provisions
specify to whom the Model ordinance applies and how the affected
parties comply with the Model Ordinance. Developers and public
agencies subject to the Model Ordinance must submit a landscape
documentation package to the appropriate city or county.
The -documentation package is to include plans and statements that
substantiate water efficient landscape design and management.
The Model Ordinance describes what the project proponent must
submit to complete the documentation package. The documentation
package consists of ten elements: (1) Water Conservation Concept
Statement, (2) Calculation of a Maximum Water Allowance, (3)
Landscape Design Plan, including plant selection and grouping,
(4) Irrigation Design Plan, including the use of recycled water,
(5) Irrigation Schedules, (6) Landscape Maintenance Schedules,
(7) Landscape Irrigation Audit Schedules, (8) Grading Design
Plan, (9) Soil Analysis, and (10) Certification. .This section
also has provisions for public education on water efficient
landscaping.
Landscape irrigation audits are to be, at a minimum, in
accordance with the California Landscape Water Management Program
as described in the Landscape Irrigation Auditor Handbook, the
entire document which is incorporated by reference in the Model
Ordinance. (See Landscape Irrigation Auditor Handbook, Dept. of
Wat. Resources, Wat. Conservation Office (June 1990) version 5.5
(Formerly Master Auditor Training].)
Section ,01 includes provisions that pertain to existing
landscapes and that apply to cities and counties that are also,
water purveyors. These provisions include water management
schedules and water waste prevention.
Section 704 provides a table of Reference Evapotranspiration
numbers'that are used to calculate maximum water allowances.
Reference Evapotranspiration is a standard measurement of
environmental parameters that affect the water use of plants.
0 •
prescriptive standards.
(D) Exemption or partial exemption from the regulatory
requirements for small businesses.
Significant effect on housing cost: Minimal. Homeowner provided
landscaping at single-family and multi -family homes and projects
with a landscaped area less than 1,000 square feet will not be
affected by the Model ordinance.
Developer installed landscapes at single-family and multi -family
residences are subject to the Model Ordinance. Additional cost
associated with the Model Ordinance could include:
* costs associated with additional document processing
and certification through the local agency planning
department;
* additional expense associated with installation of a
separate landscape meter, rain shut off devices, and
automatic controllers;
* additional expense associated with developing
irrigation schedules, conducting an irrigation audit,
conducting a soil test, and scheduling maintenance
tasks.
In many cases, the cost of installing and maintaining water
efficient landscapes as detailed in the Model Ordinance would not
exceed the cost of installing and maintaining landscapes not
subject to the ordinance. The difference in cost could range
from $500 to $1000 per project, depending upon the equipment
selected, local review fees and procedures, and the hourly rates
of local landscape professionals.
CONSIDERATION OF ALTERNATIVES:
In accordance with Government Code section 11346.5,
subdivision (a)(7), the Department must determine that no
alternative considered by it would be more effective in carrying
out the purpose for which the action is proposed or would be as
effective and less burdensome to affected private persons than
the proposed action.
The Department invites interested persons to present statements
or arguments with respect to alternatives to the proposed
regulations at the above mentioned hearing or during the written
comment period. The Department is especially interested in
receiving comments on the effect of the Model Ordinance to limit
the use of certain high water using plants, such as turf,
including comments discussing whether the evapotranspiration (ET)
adjustment factor is too high or too low; and whether
precipitation should be included in calculations for maximum

701. Definitions.
The words used in this ordinance have the meaning
set forth below:
(a) "anti -drain valve" or "check valve" means
a valve located
under a sprinkler head to hold water in the system_
so it minimizes
drainage from the lower elevation sprinkler heads
Lb) "application rate" means the depth of water
applied to a
given area usually measured in inches per hour
(c) "automatic controller" means a mechanical
or solid state

reverse flow of water from the irrigation system
(e) "conversion factor (0 62)" means a number
that converts
the maximum 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.)
(f) "emitter" means drip irrigation fittings that deliver
water
slowly from the system to the soil
7
(n) "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
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.
(o) 'landscape irrigation audit" means a process to perform
site inspections evaluate irrigation systems and develop efficient
irrigation schedules.
(p) "landscaped area" 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.
(q) "lateral line" means the water delivery pipeline that supplies
water to the emitters or sprinklers from the valve
(r) "main line" means the pressurized pipeline that delivers water
from the water source to the valve or outlet.
(s) "maximum water allowance" means for design purposes the
upper limit of annual water use for the established landscaped area
as specified in Section 702 (c) it is based upon the area's reference
evapotranspiration,the ET Adjustment Factor, and the size of the
landscaped area The amount of water recommended on an annual
basis in the irrigation schedule shall not exceed the maximum water
allowance.
W "mulch" means any material such as leaves bark straw or
other materials left loose and applied to the soil surface to reduce
evaporation.
(u) "operating pressure" means the pressure at which a system
of sprinklers is designed to operate usually indicated at the base of
E
(bb) "run off" 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.
(cc) "soil moisture sensing device" means a device that
measures the amount of water in the soil.
(dd) "soil texture" means the classification of soil based on the
percentage of sand, silt, and clay in the soil.
(ee) "sprinkler head" means a device which sprays water through
a nozzle.
(ff) "static water pressure" means the pipeline or municipal
water supply pressure when water is not flowing_
(gg) "station" means an area served by one valve or by a set of
valves that operate simultaneously.
hh) "turf" means a surface laver of earth containing mowed ara

Zoysiagrass, and Buffalo grass are warm -season grasses.
(ii) "usable precipitation"
or "effective
rainfall" means the
amount of precipitation
that
contributes to the
water needs of the
plants. Irrigation scheduling
should be adjusted
to reflect usable
precipitation. However,
for
purposes of calculating
the maximum
water allowance
and estimating
water use. usable
precipitation is
not to be included as a factor.
GO "valve" means a device used to control the flow of water in
the irrigation system.

RE: Replacing city parking spots with turf
Dear Council Members:
One would hope that their local council would demonstrate
integrity in choosing proper drought resistant landscaping
instead of planting grass. The City Council should rise to
the occasion based on principle especially at this critical
time. If money is at issue you should plant less or nothing
and feel proud that you were able to deal with "dirt" instead
of guilt.
I am angered by the shortsighted and irresponsible attitude
of the Newport Beach City Council. Planting the turf at this
time sets a poor example to everyone who passes the City
Hall. You had the opportunity to educate, set priorities,
stand on principle and you lost it.
It is poor decisions such as this that will alienate your
community. It really does not take much to see through the,
"Do as I say, not as I do" mentality. It is times like this
that I am grateful to my ignorance of your past voting
record. �--
Sincerely disappointed, a4

CITY COUNCIL AGENDA
ITEM NO. J-5
TO: City Council
FROM: Public Works Department
SUBJECT: LANDSCAPING IN FRONT OF CITY HALL
DISCUSSION:
The Planning Commission has suggested that the new area
in front of City Hall that is being created by the elimination of
parking be landscaped using drought resistant plant material.
The Newport Boulevard widening project provides $7,000
for the installation of an irrigation system and turf in an area of
approximately 16,000 square feet.
Three options are available: .
1. Install turf and irrigation as planned.
2. Hire a landscape architect to prepare a plan for
xeriscape and budget the additional funds to install
xeriscape through a separate contract.
3. Install the irrigation system as planned in the
Newport Boulevard widening project and delete the
turf. The Parks, Beaches and Recreation Department
would maintain the dirt area until such time as
water is more plentiful when turf could be
installed.
option 1 is currently part of an existing project and can
be accomplished at no additional cost and no delay. This option
could be completed in approximately 70 days.
Option 2 will require a consultant contract and the time
necessary to design, prepare a contract, advertise for bids, and,
install the xeriscape system with walkway and lighting. This
process can probably be accomplished in 120 to 180 days. A
landscape architect was contacted and asked to review the concept
of installing xeriscape in the 401± strip and made the following
observations:
1. The xeriscaping of the 16,000 sq. ft. strip would
create an ununified landscape in front of City Hall
which could be undesirable. A new demonstration
garden, which strictly respects the alignment of
Newport Boulevard placed next to existing landscape,
would be distinctly discontinuous. If constructed,
this Option may have a cost range of $165,000 to
$275,000.
Subject: Landscaping in Front of City Hall
May 13, 1991
Page 2
• 2. If the entire area in front of City Hall is revised
to create a new design coordinated with the City
Hall entrance, a more unified, continuous - landscape
could be coordinated with revised and new physical
features. This design could incorporate a water
feature and/or art work. This Option may have a
cost range of $385,000 to $825,000.
The higher cost estimate in each of these suboptions could include
added amenities such as raised planters, recirculating fountain,
plaza area, meandering walks, labeled plant identification, and a
drip irrigation exhibit. The estimated $7,000 which will be
deleted from the Newport Boulevard project could be applied to this
figure.
Option 3 is recommended by the Parks, Beaches and
Recreation Department. There would be a saving of approximately
$4,500 for turf installation that could be set aside for a future
installation of turf.
Since the contractor has removed the parking in front of
• City Hall, the business men in the area expressed concern over loss
of parking or the moving of parking to a new location. The staff
has had complaints that there are too many blue permit meters, and
another group has complained that there are not enough blue meters.
The ratio of blue meters provided is being reviewed. However, it
is probable that no solution will.be completely satisfactory to all
parties.

CITY OF NEWPORT BEACH
Parks, Beaches and Recreation Department
DATE: March 14, 1991
TO: Robert L. Wynn, City Manager
FROM: Parks, Beaches and Recreation Director
SUBJECT: PLANNING COMMISSION LETTER REGARDING
LAWN AT CITY HALL
RECOMMENDATION•
Proceed with the contract as awarded but do not install turf until
the drought is over and water becomes available.
The above recommendation is based on the following:
1. When water becomes available, the planned irrigation system
will have been installed.
2. To convert to a drought resistant planting area would require
a change order and redesign by a landscape architect, an
expense that could be avoided if turf is desired in the
future.
3. Water and maintenance requirements have not increased as the
new turf area is equal to that removed to accommodate parking
on 32nd Street.
I have met with the Public Works Department several times and, as
this is their project, they may have different ideas on this
matter. This Department, of course, will maintain the area as the
completed project scope is determined.

February 27, 1991
Honorable City Council
City of Newport Beach
3300 Newport Blvd.
Newport Beach, CA 92658
Dear Councilmembers:
At the Planning Commission meeting of February 21, 1991, the subject of the current water
crisis was raised with specific recognition given to the positive efforts of the Utilities
Department to convey the need for water conservation to our residents. The Commission
further discussed additional constructive steps that the City could take and demonstrate, by
way of example, measures which individuals and families could do on their own. It was
further noted that the City currently plans to turf an additional 1600 square feet of land in
front of City Hall as part of the Newport Boulevard street widening project. Given the fact
that grass requires a large amount of water, not to mention maintenance, it was felt that
additional lawn, during this period of prolongeddrought, was inappropriate. The Planning
Commission therefore recommends to the City Council that you seriously consider .the
installation of a drought-resistent demonstration garden in front of City Hall. Said garden
could be improved with native drought-resistent plants, shrubs and trees, and watered with
a drip irrigation system. If properly planned and carried -out, the Commission feels that such
a project would be a positive water conservation measure and provide property owners with
a unique opportunity to view drought-resistent landscaping in their own back yard. It was
further felt that the commercial nurseries in the City may also wish to participate in such
a project.

Your letter to Mayor Sansone regarding the additional landscaping of Hoag Hospital and
the existing waste and increased use of water for irrigation has been referred to me for a
response.
I intend to address your concerns in three ways. First, I am forwarding a copy of your letter
of March 20, 1992, to Mr. Michael D. Stephens, President of Hoag Hospital, in hopes that
there are some immediate steps that can be taken to reduce the waste of water that you
have observed. Second, there are three mitigation measures which have been incorporated
into the recommendations of the Planning Commission as follows:
10. Prior to the issuance of grading permits, the project sponsor
shall submit a landscape plan which includes a maintenance
program to control the use of fertilizers and pesticides, and an
irrigation system designed to minimize surface runoff and
overwatering. This plan shall be reviewed by the Department
of Parks, Beaches and Recreation and approved by the City of
Newport Beach Planning Department.
43. Prior to issuance of grading and building permits, the project
sponsor shall ensure that a landscape and irrigation plan is
prepared for each building/improvement within the overall
Master Plan. This plan shall be prepared by a licensed
landscape architect. The landscape plan shall integrate and
phase the installation of landscaping with the proposed con-
struction schedule. The plan shall be subject to review by the
Parks, Beaches and Recreation Department and approval by
the Planning Department and Pubic Works Department.
3300 Newport Boulevard, Newport Beach
Ms. Wanda Davis -2- April 7, 1992
79. Prior to the issuance of building- permits, the project sponsor
shall demonstrate that final design of the project shall provide
for the incorporation of water -saving devices for project
lavatories and other water -using facilities. The project sponsor
will also comply with any other City adopted water conservation
policies.
Third, the California Water Conservation in Landscaping Act of 1990, requires each city and
county in the state to either adopt a Water Efficient Landscape Ordinance by January 1,
1993, or issue findings that no ordinance is necessary. Toward this end, the State
Department of Water Resources plans to complete the formal adoption process of a Model
Efficient Landscape Ordinance by mid-July,1992. I would imagine that the City of Newport
Beach will either adopt the state model ordinance or modify the regulations to meet our
local conditions. If this is the case, the new regulation would apply to all of the larger
development projects where new landscaping is being installed or where existing landscaping
is being rehabilitated.
I hope this response addresses your concerns. If you have any questions or desire additional
information, I may be contacted at 644-3222.
Very truly yours,

Although I think it is wonderful to have 4 fine.hospital in our
community, I have one grave concern. Several times I'have seen
a huge waste of water on their grounds. I was attending meetings
thera.at.iight:and sprinklers were on.. when. I. arrived.and were sti11
on in the same locations when I left two hour later. That is an
extreme waste of water.
Now, with their planned expansion, they'intend to add.more
landscaping which will require even more water. If they are
as lax with this additional use of water as previously noted,
please think'of what an abuse that is:
I have abided by the request to conserve water in any way I can.
Is the hospital exempt? Shouldn't they monitor the use of
water as the rest of the good ctttzens.do?'
Please pass this along to the members of the City Council and have
them make water conservation a stipulation in their approval of
Hoag Hospital's master'.plan.
I would appreciate a sincere reply' --:.'not a placating, routine %
letter. (I have almost lost faith in 'any government•.agency --
city, county, state, federal) but I'm still trying.

with the provisions of this article, "flood -
plain" district, when it can be shown that
any of the following circumstances or condi-
tions are present:
(1) The zoning map includes property
within an FP district that is found to be
not within a floodplain area due to
incorrect preparation of the zoning map
or to physical alteration of surrounding
property which effectively removed the
subject property from the floodplain
area. The director's determination shall
be based on a study of topographic and
design flood elevation contours on the
subject property, and on such addition-
al information as is found necessary or
appropriate.
(2) Flood protective or flood control work,
adequate to protect against the design
flood and in compliance with county
flood control and flood protective stan-
dards and policies, has been completed.
The director's finding shall confirm
that any stream, channel, storm drain
or landfill improvements fully offset
flood surface elevations established by
the applicable floodplain map; and that
if the property is included on a flood
insurance rate map or a flood boundary
and floodway map, all such flood
protective or flood control work has
been approved by the appropriate
federal agency and the property re-
moved from the floodplain designation
on such maps. (Ord. No. 80-24, § 2,

terials.
(2) When the provisions of this article con-
flict with other sections of the Costa Mesa
Municipal Code, the more stringent shall apply.
(3) Any modification to an approved land-
scape or irrigation plan must be approved by
the development services director prior to in-
stallation of said landscaping or irrigation.
(4) All approvals of such plans are subject
to and dependent upon the applicant complying
with all applicable ordinances, codes, regula-
tions, adopted policies, and the payment of all
applicable fees and assessments.
(5) No final inspection or occupancy clear-
ance will be granted until all of the landscaping
and irrigation is installed in accordance with

(2) All required setbacks abutting a public
right-of-way shall be landscaped (except for
walks and driveways which provide access from
a public right-of-way).
(3) The development services director may
require landscaping in excess of the minimum
area specified for a proposed development; pro-
vided that the additional landscaping is neces-
sary to:
(a) Screen adjacent uses from parking areas,
activities, storage or structures that
could cause a negative impact on adja-
cent uses based on aesthetics, noise,
odors, etc.; or
(b) Provide landscaping that is compatible
with neighboring uses.
(4) Each landscape plan shall be compatible
with the shape and topography of the site and
the architectural characteristics of the struc-
ture(s) on the site. Each landscape plan shall
be compatible with the character of adjacent
landscaping; provided, the quality of the adja-
cent landscaping meets the standard of these
guidelines. However, it is not the intent of this
section to require the use of identical plant
materials or landscape designs. Where existing
mature landscaping is in good, healthful condi-
tion, an effort shall be made to retain and to
incorporate said landscaping into the overall
landscape theme.
(5) Each landscape plan shall illustrate a
concern for design elements such as balance,
scale, texture, form and unity.
(6) Each landscape plan shall address the
functional aspects of landscaping such as drain-
age, erosion prevention, wind barriers, provi-
sions for shade, reduction of glare. Each land-
scape plan shall demonstrate a concern for
solar access, including exposure and shading of
window areas.
(7) The plant material selected shall be suit-
able for the given soil and climate conditions.
(8) Landscaping shall be used to relieve solid,
unbroken elevations and to soften continuous
wall expanses.
(9) Materials such as crushed rock, redwood
chips, pebbles and stone are not satisfactory
substitutes for live plant materials although
their limited use may be approved by the de-
velopment services director. Artificial plants are
not acceptable.
(10) Landscaping shall be maintained in an
orderly and healthy condition. This shall include
proper pruning, mowing of lawns, weeding, re-
moval of litter, fertilizing, replacement of plants
when necessary, and regular watering.

(11) Landscaping may be required to screen
storage areas, trash enclosures, parking areas,
public utilities, freeways, highways, and other
similar land uses or elements which do not con-
tribute to the enhancement of the surrounding
area. Where plants are required for screening,
such screening shall consist of the use of ever-
green shrubs (minimum five (5) gallons), and/
or trees closely spaced.
(12) Perimeter landscaping adjacent to the
property lines is encouraged in parking areas.
Planter area curbs may be used in place of
wheel stops.
(13) All landscaping shall be separated from
parking and vehicular circulation areas by a
raised, continuous six-inch Portland cement
concrete curb. Other materials which accom-
plish the same purpose may be approved by the
development services director.
(14) Landscaping within the interior of
parking areas shall be provided in accordance
with the requirements of the underlying zone.

NOTICE OF PROPOSED RULEMAKING
NOTICE OF PROPOSED ADOPTION OF A MODEL WATER EFFICIENT LANDSCAPE
ORDINANCE TO IMPLEMENT THE WATER CONSERVATION IN LANDSCAPING ACT
NOTICE:
The Department of Water Resources (Department) proposes to adopt
the Model Water Efficient Landscape Ordinance (Model Ordinance)
to implement the Water Conservation in Landscaping Act, Statutes
of 1990, Chapter 1145, after considering all comments,
objections, or recommendations regarding the proposed action.
PROPOSED ACTION:
The Department proposes to adopt sections 700 through 704 in
Chapter 7, Division 2 of Title 23 of the California Code of
Regulations. These sections pertain to.a Model Water Efficient
Landscape Ordinance that would apply to cities and counties that
have not adopted a water efficient landscape ordinance or that
have not adopted findings that such an ordinance is unnecessary.
PUBLIC HEARING:
The Department will conduct two public hearings on the proposed
Model Ordinance: one on October 2, 1991, at 9:00 a.m. in The
State Office Building, Room 1138, 107 South Broadway, Los
Angeles, California; and -"another on October 8, 1991, at 9:00 a.m.
in the Auditorium of the Resources Building, 1416 Ninth Street,
Sacramento, California. Any person wishing to make a statement
may do so at these hearings. The Department will receive both
oral and written statemants and comments. It is requested, but
not required, that persons making oral comments at the hearings

the garage at loth and 110" Streets.
WRITTEN COMMENT PERIOD:
Any interested person, or his or her authorized representative,
may submit to the Department their written comments relevant to
the proposed regulatory action.
1
Written comments will be received until 5 p.m. on October 8,
1991.
Written comments may be delivered to:
Room 804
1416 Ninth Street
Sacramento, California,
or mailed to:
Department of Water Resources,
Water Conservation Office
Attention: Marsha Prillwitz

AUTHORITY AND REFERENCE:
Government Code section 65594 requires th
model water efficient landscape ordinance
Water Conservation in Landscaping Act of
Government Code sections 65590-65600.
INFORMATIVE DIGEST:
e Department to adopt a
that implements the
1990, codified at
In 1990 the Legislature enacted the Water Conservation ,in
Landscaping Act. The Act requires the Department to appoint an
advisory task force to work with the Department to develop a
model water efficient landscape ordinance. Thirteen
representatives of the landscape industry, the building industry,
cities, counties, water districts, and environmental
organizations composed the task force.
Cities and counties hava until January 1, 1993, to adopt the
Model Ordinance, adopt some other water efficient landscape
ordinance, or issue a finding that they do not need such an
ordinance, based upon specified factors. If a city or county
does not take any action, the Model Ordinance adopted by the
Department shall take effect on January 1, 1993, and have the
same effect as if adopted by a city or county.
The effect of the proposed Model Ordinance is to provide guidance
to cities and counties in developing their own ordinances. Also,
the proposed Model Ordinance will become effective on January 1,
1993, in cities or counties that do not adopt their own ordinance
or adopt a finding of no necessity for such an ordinance.
Section 700 of the proposed Model Ordinance clarifies the
legislative intent and describes the purpose of the ordinance.
The purpose of the Model Ordinance is to establish a structure
for designing, installing, and maintaining water efficient
landscapes. Section 701 defines terms used in the proposed Model
Ordinance. These definitions include technical terms that the
general public may find unfamiliar but are commonly used in
landscape design and terms that may appear common but have
specific meaning in the Model Ordinance.
Section 702 describes the provisions of the Model Ordinance that
apply to new or rehabilitated landscapes. These provisions
specify to whom the Model Ordinance applies and how the affected
parties comply with the Model Ordinance. Developers and public
agencies subject to the Model Ordinance must submit a landscape
documentation package to the appropriate city or county.
The documentation package is to include plans and statements that
substantiate water efficient landscape design and management.
The Model Ordinance describes what the project proponent must
submit to complete the documentation package. The documentation
package consists of ten elements: (1) Water Conservation Concept
Statement, (2) Calculation -of a Maximum Water Allowance, (3)
Landscape Design Plan, including plant selection and grouping,
(4) Irrigation Design Plan, including the use of recycled water,
(5) Irrigation Schedules, (6) Landscape Maintenance Schedules,
(7) Landscape Irrigation Audit Schedules, (8) Grading Design
Plan, (9) Soil.Analysis, and (10) Certification. This section
also has provisions for public education on water efficient
landscaping.
Landscape irrigation audits are to be, at a minimum, in
accordance with the California Landscape Water Management Program
as described in the Landscape Irrigation Auditor Handbook, the
entire document which is incorporated by reference in the Model
Ordinance. (See Landscape Irrigation Auditor Handbook, Dept. of
Wat. Resources, Wat. Conservation Office (June 1990) version 5.5
[Formerly Master Auditor Training].)
Section 703 includes provisions that pertain to existing
landscapes and that apply to cities and counties that are also
water purveyors. These provisions include water management
schedules and water waste prevention.
Section 704 provides a table of Reference Evapotranspiration
numbers that are used to calculate maximum water allowances.
Reference Evapotranspiration is a standard measurement of
environmental parameters that affect the water use of plants.
3
REGARDING THE PROPOSED ACTION:
Mandate on local agencies and school -district : Yes. Cities and
counties that have not adopted a water efficient landscape
ordinance and that do not want the Model Ordinance to apply to
them by statutory requirement must, by January 1, 1993, either
adopt a Model Ordinance or adopt findings that such an ordinance
is unnecessary based on climatic, geological, or topographical
conditions, or water availability.
Cost or savinas to anv state aaencv: None.
Cost to any local agency or school district which must be
reimbursed in accordance with Government Code section 17561:
None. No reimbursement is required because local agencies or
school districts have the authority to levy service charges,
fees; or assessments sufficient to pay for the costs associated
with adopting and implementing the Model ordinance.
None.
Cost or savinas in federal fundina to the state: None.
Cost impact on private persons or directly affected businesses:
Minimal. The cost to developers of designing and installing
water efficient landscapes may be slightly higher initially than
installing landscapes that would not have to conform to the Model
Ordinance. After this initial period, however, lower water costs
and maintenance costs should offset the initial costs.
Significant adverse economic effect on small business: Minimal.
Adoption of this Model ordinance will probably have a positive
economic effect on small landscape businesses, such as nurseries,
creating additional opportunities for landscape professionals.
However, an adverse economic effect on turf grass growers may
occur because the Model ordinance may limit the amount of high
water using plants, such as turf, on some developer installed
landscapes in certain cities and counties.
The Department finds that the adoption of this Model Ordinance
may have a significant adverse economic impact on small
businesses. The Department has considered proposed alternatives
that would lessen any adverse economic impact on small business
and invites you to submit such proposals. Submissions may
include the following considerations:
(A) The establishment of differing compliance or reporting
requirements or timetables which take into account the resources
available to small business.
(B) Consolidation or simplification of compliance and
reporting requirements for small businesses.
(C) The use of performance standards rather than
4
0
C,
prescriptive standards.
(D) Exemption or partial exemption from the regulatory
requirements for small businesses.
Significant effect on housing cost: Minimal. Homeowner provided
landscaping at single-family and multi -family homes and projects
with a landscaped area less than 1,000 square feet will not be
affected by the Model Ordinance.
Developer installed landscapes at single-family and multi -family
residences are subject to the Model,Ordinance. Additional cost
associated with the Model Ordinance could include:
* costs associated with additional document processing
and certification through the local agency planning
department;
* additional expense associated with installation of a
separate landscape meter, rain shut off devices, and
automatic controllers;
* additional expense associated with developing
irrigation schedules, conducting an irrigation audit,
conducting a soil test, and scheduling maintenance
tasks.
In many cases, the cost of installing and maintaining water
efficient landscapes as detailed in the Model Ordinance would not
exceed the cost of installing and maintaining landscapes not
subject to the ordinance. The difference in cost could range
from $500 to $1000 per project, depending upon the equipment
selected, local review fees and procedures, and the hourly rates
of local landscape professionals.
CONSIDERATION OF ALTERNATIVES:
In accordance with Government Code section 11346.5,
subdivision (a)(7), the Department must determine that no
alternative considered by it would be more effective in carrying
out the purpose for which the action is proposed or would be as
effective and less burdensome to affected private persons than
the proposed action.
The Department invites interested persons to present statements
or arguments with respect to alternatives to the proposed
regulations at the above mentioned hearing or during the written
comment period. The Department is especially interested in
receiving comments on the effect of the Model Ordinance to limit
the use of certain high water using plants, such as turf,
including comments discussing whether the evapotranspiration (ET)
adjustment factor is too high or too low; and whether
precipitation should be included in calculations for maximum
,.
5
water allowance or in the estimation of water use. The
Department also invites comments regarding the use of a maximum
water allowance not to exceed a statewide specified amount.

701. Definitions.
The words used in this ordinance have the meaning set forth below:
(a) "anti
-drain
valve" or "check
valve"
means a valve located
under
a sprinkler
head to hold water
in the
system so it minimizes
drainage
from the
lower elevation
sprinkler
heads.
(b) "application rate" means the depth of water applied to a
given area, usually measured in inches per hour.
(g) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to -set the days and length
of time of a water application.
(d) "backflow 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.
(e) "conversion factor (0.62)" means a number that converts
the maximum water allowance from acre -inches per acre per year to
oallons per square foot Der vear. 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.)
(f)__ "emitter" means drip irrigation fittings that deliver water
slowly from the system to the soil.
6
(g) "established
landscape"
means the
point at which
plants ih
the landscape
have developed
roots into the
§oil adjacent
to the root
DAIL
(h) "establishment
period"
means the
first year after
installing
the plant in the
landscape.
(1) "ET adjustment
factor"
means a factor
of 0.8. that,
when
applied to reference
evapotranspiration.
adjusts
for plant
factors
and irrigation
efficiency. two m
'or influences
upon the
amount of
supplemental 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, ET
Adjustment Factor
(0.8) = (0.5/0.625).
(j) "evapotranspiration"
means
the quantity
of water
evaporated
from a 'scent
soil surfaces and
transpired by
plants during
a
specific time.
(k) "flow rate".
means the rate
at which
water flows
through
pipes and valves
(gallons or cubic
feet per second).
(1) "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.
(m) "infiltration
rate" means
the rate of
water entry
into the
soil expressed
ass depth of water
per unit of
time (inches
per hour).
7
(n) "irrigation
efficiency"

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
ordinance
is 0.625. Greater
irrigation efficiency can be
expected
from well
designed and maintained
systems.
(g) "landscape Irrigation audit" means a process to perform
site inspections evaluate irrigation systems and develop efficient
irrigation schedules. _
"landscaped area" means the _entire parcel less the buildin
footprint
driveways non -irrigated portions
of parking
lots
hardscapes-
such as decks and patios
and other
non -porous areas
Water features

(q) "lateral line" means the water delive!y pipeline that supplies
water to the emitters or sprinklers from the valve.
(r) "main line" means the pressurized pipeline that delivers water
from the water source to the valve or outlet.
s) "maximum water- allowance" means, for design purposes, th
upper limit of annual water use for the established landscaped area

evapotranspiration the ET Adjustment Factor, and the size of the
landscaped area. The amount of water recommended on an annual
basis in the irrigation schedule shall not exceed the maximum water
allowance.
(0 "mulch" means any material such as leaves bark straw or
other materials left loose and applied to the soil surface to reduce
evaporation.

Study Session Item No. &—
CITY OF NEWPORT BEACH
TO: Mayor and Members of the City Council
FROM: Planning Department6l;A
SUBJECT: Proposed Water Efficient Landccane Ordinance
Review and discussion of a proposed amendment to Title 14 of the
Newport Beach Municipal Code pertaining to the establishment of
provisions for the design, installation and maintenance of water
efficient landscapes.
In 1990, the State Legislature adopted Assembly Bill 325 (AB 325) which established
requirements for cities and counties to adopt local water efficient landscape ordinances.
The bill also provides that if any local agency has not adopted its own ordinance by January
1,1993, or adopted findings that no ordinance is necessary, based on specific findings.baving
to do with climate, geology, topography or water availability, the Model Water Efficient
Landscape Ordinance (Model Ordinance) adopted by the Department of Water Resources
shall take effect and shall be enforced by the local agency. Should a local agency choose
to adopt its own ordinance, Section 65596 of the bill requires that the local agency shall "to
the extent feasible" consider the provisions of the model ordinance in conjunction with the
adoption of its own ordinance. For this reason, staff has attached a copy of the State's
Model Ordinance and a summary of the key provisions as they apply to the City of Newport
Beach.
It should be noted that although Section 65597 of AB 325 specifies that certain provisions
shall be included in the Model Ordinance, there is nothing in the bill that states what a local
ordinance must contain, nor does the State of California have any review authority over any
ordinance adopted by a local agency. It simply requires the local agency to consider the
Model Ordinance.
Suooested Time Table for Council Actions
Inasmuch as the City's ordinance is required to be adopted by January 1, 1993 and
forwarded to the California Department of Water Resources by January 31, 1993, the
following time table for City Council actions is suggested:
November 9, 1992 City Council reviews draft ordinance at Study Session.
November 23, 1992 City Council introduces ordinance and sets public
hearing for December 14, 1992.
TO: CiAouncil - 2
December 14, 1992 If desired, City Council adopts ordinance.
January 13, 1993 Ordinance goes into effect.
January 14, 1993 City sends copy of ordinance to the Califortia
Department of Water Resources.
Provisions of Stare Model Water Efficient Landscape Ordinan
Section 490 of the Model Ordinance clarifies the legislative intent and describes the purpose
of the ordinance. The purpose of the Model Ordinance is to establish a structure for
designing, installing and maintaining water efficient landscapes. Section 491 defines terms
used in the proposed Model Ordinance. These definitions include technical terms that the
general public may find unfamiliar but are commonly used in landscape design and terms
that may appear common but have specific meaning in the Model Ordinance.
Section 492 describes the provisions of the Model Ordinance that apply to new and
rehabilitate landscapes. These provisions specify to whom the ordinance applies and how
the affected parties comply with the ordinance. Projects affected by the ordinance include
all new and rehabilitated landscaping for public agency projects and private commercial and
industrial development projects containing 2,500 square feet or more of landscaping; and
developer installed landscaping in single family and multi -family projects containing 2,500
square feet of landscaping or more.
Developers and public agencies subject to the ordinance must submit a landscape
documentation package to the appropriate city or county. The documentation package is
to include plans and statements that substantiate water efficient landscape design and
management. The Model Ordinance describes what the project proponent must submit to
complete the documentation package which consists of ten elements: (1) Water
Conservation Concept Statement, (2) Calculation of a Maximum Water Allowance, (3)
Landscape Design Plan including plant selection and grouping, (4) Irrigation Design Plan,
including the use of recycled water, (5) Irrigation Schedules, (6) Landscape Maintenance
Schedules, (7) Landscape Irrigation Audit Schedules, (8) Grading Design Plan, (9) Soil
Analysis, (10) Certification. This section also has provisions for public education on water
efficient landscaping. Landscape irrigation audits are to be, at a minimum, in accordance
with the California Landscape Water Management program as described in the Landscape
Irrigation Auditor Handbook, the entire document which is incorporated by reference in the
Model Ordinance. (A copy of this document is on file in the Planning Department).
Section 493 includes provisions that pertain to existing landscapes and that apply to cities
and counties that are also water purveyors. These provisions include water management
schedules and water waste prevention.
Section 494 provides a sample Effective Precipitation Disclosure Statement and Section 495
provides a table of Reference Evapotranspiration numbers that are used to calculate
maximum water allowances. Reference Evapotranspiration is a standard measurement of
environmental parameters that affect the water use of plants.
Co
TO: City uncil - 3 •
As indicated previously, staff has attached a copy of the State's model ordinance and a
summary of key provisions as they apply to the City's responsibilities under the ordinance.
Essential Provisions of City's Ordinan
The City's proposed Water Efficient Landscape Ordinance is very similar to the State's
Model Ordinance. However, there are some significant differences that should be noted.
The key aspect of the State's Model Ordinance is that applicable projects will be required
to design, install and maintain landscapes that do not exceed a specific amount of water
which the Model Ordinance refers to as, the Maximum Applied Water Allowance. This
water budget approach to controlling the design of landscapes and regulating the amount
of water allocated to a specific landscape, is quite burdensome and somewhat restrictive.
Therefore, in drafting the City's Water Efficient Landscape Ordinance, the water budget
provisions have been eliminated. Inasmuch as there is no water budget provisions, the
requirement for periodic water audits has also been eliminate.
The applicability provisions of the City's ordinance are essentially the same as the State
Model Ordinance; however, some clarifying language has been added to.the City's ordinance
which links applicable landscape projects with private development projects that are done
in conjunction with the issuance of building permits or grading permits for the construction
of new structures or rehabilitation of existing structures. Such linkage is necessary inasmuch
as the City does not currently require separate permits for the installation of landscaping.
Applicable projects will still have to be designed in an efficient manner, utilizing the
grouping of plants into hydrozones; and by selecting plants that are adaptable to the climate,
geology and topography of the site. Irrigation systems will still have to utilize equipment
and be designed in a manner so as to eliminate runoff, overspray and misting; and irrigation
schedules will still be required which take into consideration plant characteristics and soil
conditions. However, there is no provision which restrict the amount of water which may
be allocated to a specific landscape. It is staffs opinion that the real incentive for installing
and maintainfng-water efficient landscapes has to do with the economic benefits to do so.
Therefore, it is important for the City's ordinance to be linked to water rate schedules which
reward customers for establishing water efficient landscapes and penalize those that do not.
In light of this approach, staff has forwarded a copy of the City's proposed ordinance to the
Utilities Committee for their review and comment.

CITY OF NEWPORT BEACH
TO: Mayor and Members of the City Council
FROM: Planning Department6l4k
SUBJECT: Proposed Water Efficient Landscape Ordinance
Review and discussion of a proposed amendment to Title 14 of the
Newport Beach Municipal Code pertaining to the establishment of
provisions for the design, installation and maintenance of water
efficient landscapes.
Backaround
In 1990, the State Legislature adopted Assembly Bill 325 (AB 325) which established
requirements for cities and counties to adopt local water efficient landscape ordinances.
The bill also provides that if any local agency has not adopted its own ordinance by January
1,1993, or adopted findings that no ordinance is necessary, based on specific findings having
to do with climate, geology, topography or water availability, the Model Water Efficient
Landscape Ordinance (Model Ordinance) adopted by the Department of Water Resources
shall take effect and shall be enforced by the local agency. Should a local agency choose
to adopt its own ordinance, Section 65596 of the bill requires that the local agency shall "to
the extent feasible" consider the provisions of the model ordinance in conjunction with the
adoption of its own ordinance. For this reason, staff has attached a copy of the State's
Model Ordinance and a summary of the key provisions as they apply to the City of Newport
Beach.
It should be noted that although Section 65597 of AB 325 specifies that certain provisions
shall be included in the Model Ordinance, there is nothing in the bill that states what a local
ordinance must contain, nor does the State of California have any review authority over any
ordinance adopted by a local agency. It simply requires the local agency to consider the
Model Ordinance.
Suggested Time Table for Council Actions
Inasmuch as the City's ordinance is required to be adopted by January 1, 1993 and
forwarded to the California Department of Water Resources by January 31, 1993, the
following time table for City Council actions is suggested:
November 9, 1992 City Council reviews draft ordinance at Study Session.
November 23, 1992 City Council introduces ordinance and sets public
hearing for December 14, 1992.
TO: Cityfouncil - 2 •
December 14, 1992 If desired, City Council adopts ordinance.
January 13, 1993 Ordinance goes into effect.
January 14, 1993 City sends copy of ordinance to the California
Department of Water Resources.
Provisions of State Model Water Efficient Landscape Ordinan
Section 490 of the Model Ordinance clarifies the legislative intent and describes the purpose
of the ordinance. The purpose of the Model Ordinance is to establish a structure for
designing, installing and maintaining water efficient landscapes. Section 491 defines terms
used in the proposed Model Ordinance. These definitions include technical terms that the
general public may find unfamiliar but are commonly used in landscape design and terms
that may appear common but have specific meaning in the Model Ordinance.
Section 492 describes the provisions of the Model Ordinance that apply to new and
rehabilitate landscapes. These provisions specify to whom the ordinance applies and how
the affected parties comply with the ordinance. Projects affected by the ordinance include
all new and rehabilitated landscaping for public agency projects and private commercial and
industrial development projects containing 2,500 square feet or more of landscaping; and
developer installed landscaping in single family and multi -family projects containing 2,500
square feet of landscaping or more.
Developers and public agencies subject to the ordinance must submit a landscape
documentation package to the appropriate city or county. The documentation package is
to include plans and statements that substantiate water efficient landscape design and
management. The Model Ordinance describes what the project proponent must submit to
complete the documentation package which consists of ten elements: (1) Water
Conservation Concept Statement, (2) Calculation of a Maximum Water Allowance, (3)
Landscape Design Plan including plant selection and grouping, (4) Irrigation Design Plan,
including the use of recycled water, (5) Irrigation Schedules, (6) Landscape Maintenance
Schedules, (7) Landscape Irrigation Audit Schedules, (8) Grading Design Plan, (0) Soil
Analysis, (10) Certification. This section also has provisions for public education on water
efficient landscaping. Landscape irrigation audits are to be, at a minimum, in accordance
with the California Landscape Water Management program as described in the Landscape
Irrigation Auditor Handbook, the entire document which is incorporated by reference in the
Model Ordinance. (A copy of this document is on file in the Planning Department).
Section 493 includes provisions that pertain to existing landscapes and that apply to cities
and counties that are also water purveyors. These provisions include water management
schedules and water waste prevention.
Section 494 provides a sample Effective Precipitation Disclosure Statement and Section 495
provides a table of Reference Evapotranspiration numbers that are used to calculate
maximum water allowances. Reference Evapotranspiration is a standard measurement of
environmental parameters that affect the water use of plants.
TO: Citylpouncil - 3 •
As indicated previously, staff has attached a copy of the State's model ordinance and a
summary of key provisions as they apply to the City's responsibilities under the ordinance.
Essential Provisions of City's Ordinan
The City's proposed Water Efficient Landscape Ordinance is very similar to the State's
Model Ordinance. However, there are some significant differences that should be noted.
The key aspect of the State's Model Ordinance is that applicable projects will be required
to design, install and maintain landscapes that do not exceed a specific amount of water
which the Model Ordinance refers to as, the Maximum Applied Water Allowance. This
water budget approach to controlling the design of landscapes and regulating the amount
of water allocated to a specific landscape, is quite burdensome and somewhat restrictive.
Therefore, in drafting the City's Water Efficient Landscape Ordinance, the water budget
provisions have been eliminated. Inasmuch as there is no water budget provisions, the
requirement for periodic water audits has also been eliminate.
The applicability provisions of the City's ordinance are essentially the same as the State
Model Ordinance; however, some clarifying language.has been added to the City's ordinance
which links applicable landscape projects with private development projects that are done
in conjunction with the issuance of building permits or grading permits for the construction
of new structures or rehabilitation of existing structures. Such linkage is necessary inasmuch
as the City does not currently require separate permits for the installation of landscaping.
Applicable projects will still have to be designed in an efficient manner, utilizing the
grouping of plants into hydrozones; and by selecting plants that are adaptable,to the climate,
geology and topography of the site. Irrigation systems will still have to utilize equipment
and be designed in a manner so as to eliminate runoff, overspray and misting; and irrigation
schedules will still be required which take into consideration plant characteristics and soil
conditions. However, there is no provision which restrict the amount of water which may
be allocated to a specific landscape. It is staffs opinion that the real incentive for installing
and maintaining water efficient landscapes has to do with the economic benefits to do so.
Therefore, it is important for the City's ordinance to be linked to water rate schedules which
reward customers for establishing water efficient landscapes and penalize those that do not.
In light of this approach, staff has forwarded a copy of the City's proposed ordinance -to the
Utilities Committee for their review and comment.

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 economic • 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

491. Definitions.
The words used in this ordinance have the meaning set forth below:
(a) "anti -drain valve" or "check valve" means a valve located
under a sprinkler head to hold water in the system so it minimizes
drainage from the lower elevation sprinkler heads.
(b)
napplication
rate" means the depth
of water applied to a
given
area, usually
measured in inches per
hour.
(c) "applied water" means the portion of water supplied by the
irrigation system to the landscape.
(d) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to set the days and length
of time of a water application.
(a) "backflow 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 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
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.)
a/
6
(g) ecological restoration project" means a project where the
site is intentionally altered to establish a defined, indigenous,
historic ecosystem.
(h) "effective precipitation" or "usable rainfall' 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.
(1) "emitter"
means
drip
irrigation fittings that deliver water
slowly from the
system
to
the soil.
0) "established landscape means the point at which plants in
the landscape have developed roots into the soil adjacent to the root
ball.

the plant in the landscape.
(1) Estimated Applied Water. Use" means the portion of the
Estimated Total Water Use that 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, as
referenced in Section 492 (c) (3).
(m) Estimated Total Water Use" 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, as described
in Section 492 (c) (4).
(n) IIET adjustment factoet 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.
OM

7
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).
(o) "evapotranspiration" means the quantity of water evaporated
from adjacent soil surfaces and transpired by plants during a
specific time.

established is a non -irrigated hydrozone.
(r) "infiltration rate" means the rate of water entry into the soil
expressed as a depth of water per 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
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.

water from the water source to the valve or outlet.
(x) "Maximum Applied Water Allowance" means, for design
purposes, the upper limit of annual applied water for the established
landscaped area as specified in Section 492 (c) (2). It is based upon
the area's reference evapotranspiration, the ET Adjustment Factor,

(2) The Maximum Applied Water Allowance
(A) A projects Maximum Applied Water Allowance shall be
calculated 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 50,000 sq. ft. in Fresno
MAWA = (ETo) (.8) (LA) (.6
(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: 1,264,800/748=1,691)
(ii) PROJECT 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 1,160 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.

(4) Estimated Total Water Use
(A) A calculation of the Estimated Total Water Use shall be
submitted with the Landscape Documentation Package. The
Estimated Total Water Use may be calculated by summing the
amount of water recommended in the irrigation schedule and adding
any amount of water expected from effective precipitation (not to
exceed 25 percent of the local annual mean precipitation) or may be
calculated from a formula such as the following:
The Estimated Total Water Use for the entire landscaped area equals
the sum of the Estimated Water Use of all hydrozones in that
landscaped area.
EWU (hydrozone) = (ETo) (PF) (HA) (.62)
(IE)
EWU (hydrozone) = Estimated Water Use (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
PF = plant factor
HA hydrozone area (square feet)
(.62) = conversion factor _
IE = irrigation efficiency

(1) if the project's water bills indicate that they are using less
than or equal to the Maximum Applied Water Allowance for that project
site, an audit shall not be required.
(2) Recognition of projects that stay within the Maximum Applied
Water Allowance is encouraged.
(b) Water Waste Prevention
Cities and counties shall prevent water waste resulting from
inefficient landscape irrigation by prohibiting runoff, low head drainage,
overspray, or other similar conditions where water flows onto adjacent
property, non -irrigated areas, walks, roadways, or structures. Penalties
for violation of these prohibitions shall be established locally.

SAMPLE EFFECTIVE PRECIPITATION DISCLOSURE STATEMENT
I certify that I have informed the project owner and developer that this
project depends on (gallons or cubic feet) of effective
precipitation per year. This represents percent of the local mean
precipitation of inches per year.
I have based my assumptions about the amount of precipitation that is
effective upon:
I certify that I have informed the project owner and developer that in
times of drought, there may not be enough water available to keep the
entire landscape alive.
Licensed or Certified Landscape Professional
I certify that I have been informed by the licensed or certified landscape
professional that this project depends upon (gallons or cubic feet)
of effective precipitation per year. This represents percent of
the local mean precipitation of inches per year.
I certify that I have been informed that in times of drought, there may not
be enough water available, to keep the entire landscape alive.

LEGISLATIVE COUNSELS DIGEST
AB 325, Clute. Water conservation: landscaping ordinance.
(1) Under existing law, local agencies are not required to adopt
ordinances concerning landscape water conservation.
This bill would require the Department of Water Resources lift
February 1,1991, to appoint an advisory task force to work with tHor
department in the drafting of a model water efficient landscape
ordinance and to submit the recommended ordinance to the
department by May 1,1991. The bill would require the department
by January 1, 1992, after holding a public hearing, based on
recommendations of the task force, to adopt a model local water
efficient landscape ordinance which each local agency, as defined,
may adopt. The bill would provide that if any local agency has not
adopted a water landscape ordinance or findings, based on specified
factors, that no ordinance is necessary, by January 1, 1993, the model
ordinance shall take effect and shall be enforced by that local agency
and have the same force and effect as if adopted by that local agency.
The bill would require each local agency, not later than January 31,
1993, to file with the department a copy of the water efficient
landscape ordinance adopted, or the findings which state that no
ordinance is necessary, thereby imposing a state -mandated local
program.
The bill would require the department to report to the Legislatur•
on the status of these local ordinances by July 1, 1993.
The bill would require the model ordinance to contain specified
provisions and would specify related matters.

have the meanings indicated:
A. "anti -drain valve" or "check valve" means a valve located under a
sprinkler head that holds water in the system so it minimises drainage from
the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation
system to the landscape.
D. "automatic controller" means a mechanical or solid state timer, capable
of operating valve stations which set the days and duration of a water
application.

pollution or contamination of the water supply that could result from the
reverse flow of water from the irrigation system.
F. "ecological restoration project" means a project where the site is
intentionally altered to establish a defined, indigenous, ecosystem.
G. "emitter" means drip irrigation fittings that slowly deliver water from
the system to the soil.
H. "established landscape" means the point at which plants in the
landscape have developed roots into the soil adjacent to the root ball.
I. "establishment period" means the first year after installing the plant
in the landscape.
I "Estimated Total Water Use" 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.
2
. • •
K. "evapotranspiration" means the quantity of water evaporated from
adjacent soil surfaces and transpired by plants during a specific time.
L. "flow rate" means the rate at which water flows through pipes and
valves (gallons per minute or cubic feet per second).
M. "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.
N. "infiltration rate" means the rate of water entry into the soil expressed
as a depth of water per unit of time (inches per hour).
O. "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 estimates of irrigation system
characteristics and management practices. The minimum uTigation efficiency
for purposes of this ordinance is 0.625. Greater irrigation efficiency can be
expected from well designed and maintained systems.
P. "landscape irrigation audit" means a process to perform site
inspections, evaluate irrigation systems, and develop efficient irrigation
schedules.
Q. "landscaped area" 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.
R. "lateral line" means the water delivery pipeline that supplies water to
the emitters or sprinklers from the valve.
S. "main line" means the pressurized pipeline that delivers water from
the water source to the valve or outlet.
3
0
T. "mulch" means any organic material such as leaves, bark, straw or
inorganic material such as decomposed granite other which is left loose or
applied to the soil surface to reduce evaporation.
U. "operating pressure" means the pressure at which a system of
sprinklers is designed to operate, usually indicated at the base of a sprinkler.
V. "overspray" means the water which is delivered beyond the landscaped
area, wetting pavements, walks, structures, or other non -landscaped areas.

sports fields, school yards, picnic grounds, or other areas with intense foot
traffic.
Y. "recycled water," "reclaimed water," or "treated sewage effluent water"
means treated or recycled waste water of a quality suitable for non -potable
uses such as landscape irrigation; not intended for human consumption.
Z. "reference evapotranspiration" or "Eto" means a standard measurement
of environmental parameters which affect the water use of plants. Eto is
given in inches per day, month, or year as represented in Section 705, and is
an estimate of the evapotranspiration of a large field of four- 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.
AA. "rehabilitated landscape" means any relandscaping project that is done
in conjunction with an applicable project as set forth in Section 14.17.020 A,
that requires the issuance of a building permit or grading permit for the
construction of new structures or the rehabilitation of existing structures.
BB. "run off' 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.

MEMORANDUM
PLANNING DEPARTMENT
CITY OF NEWPORT BEACH
June 19, 1992
TO: Robin Flory, Assistant City Attorney
FROM: W. William Ward, Senior Planner
SUBJECT: City's Compliance with AB 325 (Water Conservation Landscape
Ordinance)
Attached for your review and comment is information that the City has received from the
California Department of Water Resources concerning the requirement for Cities and
Counties to adopt Water Efficient Landscape Ordinances in compliance with AB 325. After
a preliminary review of this material with Jim Hewicker, it is unclear to what extent the City
must go in order to achieve compliance. The State has sent us a draft model ordinance as
a guideline for the preparation of a local ordinance. If the City does not adopt an
ordinance of their own by January 1, 1993, the State Model Ordinance goes into effect
within the City. The essential questions that Jim and I would like to discuss with you are:
1. What are the City's responsibilities under AB 325?
2. Does the State Model Ordinance represent a minimum standard? Or could the City
adopt an ordinance that is significantly different?
3. Does the State have any authority to reject the City's ordinance and impose the State
Model Ordinance?
4. What review authority does the State have regarding the City's review of applicable
projects and its determination of compliance with either a local ordinance, if
adopted, or the State Model Ordinance, in the absence of a local ordinance?
Inasmuch as I am scheduled to leave on vacation on June 26, 1992, and Jim wishes to
discuss this before I leave, it would be good if we could meet Tuesday or Wednesday of next
week. Please let me know.

March 17, 1992
To: California Cities and Counties
Subject: Adoption of the Model Water Efficient Landscape Ordinance, as
required by Assembly Bill 325
The Department of Water Resources plans to complete the formal
adoption process for the Model Water Efficient Landscape Ordinance by
mid -July, 1992. Cities and counties have until January 1, 1993 to adopt
the State Model Ordinance, their own local water efficient landscape
ordinance, or issue findings that no ordinance is necessary. If no action -is
taken, the State Model Ordinance will automatically go into effect on that
date.
if you have not adopted a local ordinance as yet, you may wish to
establish a process for deciding what provisions of the Model Ordinance
are appropriate for your own community. The enclosed version of the
Model Ordinance, dated 1/17/92, will give you a good idea of what the
final ordinance will contain.
The Model Ordinance was designed to provide a set of standard
provisions to meet the needs of a highly diverse state. The provisions
allow for flexibility in landscape design and efficient water use. It is
based upon a "water budget' approach where landscapes are designed and
maintained to stay within the amount of water budgeted per acre of
landscape.
The ordinance can and should be modified to meet local conditions.
For example, if your area has access to abundant recycled (reclaimed)
water, your jurisdiction may choose to exempt landscape projects that
use recycled water from the water efficient landscape review process.
Or, you may decide to adjust the water budget based upon your local water
supply situation. In any case, it would be a good idea to include your local
water agencies in the process as you design and implement your local
ordinance.
0 a
The Department will be working with the League of California
Cities, the County Supervisors Association, the California Landscape
Contractors Association, and others to provide more information to you
about adopting and implementing water efficient landscape ordinances.
Attached to the Model Ordinance is a copy of the law, specifying the
responsibilities of California cities and counties. Note that a copy of your
local water efficient landscape ordinance should be sent to the
Department by January 31, 1993. Please send it to the following address:

700. 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 economic 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.
Note: Authority cited: Sections 65591.5, 65594, Gov. Code. Reference:
Sections 65591, 65591.5, 65597, Gov. Code.
F
701. Definitions.
The words used in this ordinance have the meaning set forth below:
(a) "anti -drain valve" or "check valve" means a valve located
under a sprinkler head to' hold water in the system so it minimizes
drainage from the lower elevation sprinkler heads.
(b)
"application
rate" means the depth
of water applied to a
given
area, usually
measured in inches per
hour.
(c) "applied water" means the portion of water supplied by the
irrigation system to the landscape.
(d) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to set the days and length
of time of a water application.
(e) "backflow 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 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.)
0
(g) ecological restoration project" means a project where the
site is intentionally altered to establish a defined, indigenous,
historic ecosystem.
(h) "effective precipitation" or "usable rainfall" 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. it the
........_,._..._-------------
(i) "emitter" means drip irrigation fittings that deliver water
slowly from the system to the soil.
(j) "established landscape" means the point at which plants in
the landscape have developed roots into the soil adjacent to the root
ball.
(k) "establishment period" means the first year after installing
the plant in the landscape.
(1) "Estimated Applied Water Use" means the portion of the
Estimated Total Water Use that 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, as
referenced in Section 702 (c) (3).
(m) "Estimated Total Water Use" 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, as described
in Section 702 (c) (4).
�J
n
LA
7
(n) "ET adjustment factor" 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).
(o) "evapotranspiration" 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 per 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
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"
site inspections, evaluate irrigation
irrigation schedules.
3
means a process to perform
systems, and develop efficient
(u) "landscaped area".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.

water to the emitters or sprinklers from the valve.
(w) "main line" means the pressurized pipeline that delivers
water from the water source to the valve or outlet.
(x) "Maximum Applied Water Allowance" means, for design
purposes, the upper limit of annual applied water for the established
landscaped area as specified in Section 702 (c) (2). It is based upon
the area's reference evapotranspiration, the ET Adjustment Factor,
and the size of the landscaped area. The Estimated Applied Water

of sprinklers is designed to operate, usually indicated at the base of
a sprinkler.
E
(bb) "overspray" means the water which is delivered beyond the
landscaped area, wetting pavements, walks, structures, or other non -
landscaped areas.
(cc) "plant factor" means a factor 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.
(dd) "rain sensing device" means a system which automatically
shuts off the irrigation system when it rains.
(ee) "record drawing" or "as-builts" 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.

sewage effluent water" means treated or recycled waste water
of a quality suitable for nonpotable uses such as landscape
irrigation; not intended for human consumption.
(hh) "reference evapotranspiration" or "ETo" means a
standard measurement of environmental parameters which affect
the water use of plants. ETo is given in inches per day, month, or
year as represented in Section 705, and is an estimate of the
evapotranspiration of a large field of four- 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.
10
(ii) "rehabilitated landscape" means any relandscaping project
that requires a permit.
0j) "run off" means water which is not absorbed by the soil or
landscape to which it is applied and flows from the area. For

(2) The Maximum Applied Water Allowance
(A) A projects Maximum Applied Water Allowance shall be
calculated 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 50,000 sq. ft. in Fresno
MAWA = (ETo) (.8) (LA) (.62)
_ (51 inches) (.8) (50,000 square feet) (.62)

given in inches per day, month, or year as represented in Section 705, and is
an estimate of the evapotranspiration of a large field of four- 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.
AA. "rehabilitated landscape" means any relandscaping project that is done
in conjunction with an applicable project as set forth in Section 14.17.020 A,
0 •
that requires the issuance of a building permit or grading permit for the
construction of new structures or the rehabilitation of existing structures.
BB. "run off' 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

Item No. 2
CITY OF NEWPORT BEACH
TO: Mayor and Members of the City Council
FROM: Planning Depaztment��
SUBJECT: Proposed Water Efficient Landscape Ordinance
Request to consider a proposed amendment to Title 14 of the Newport
Beach Municipal Code pertaining to the establishment of provisions
for the design, installation and maintenance of water efficient
landscapes.
Request to consider an amendment to Title 14 of the Newport Beach Municipal Code
pertaining to the establishment of provisions for the design, installation and maintenance
of water efficient landscapes.
Hold hearing; close hearing; if desired, adopt Ordinance No. 22_-�4 as introduced on
November 23rd and as set forth in Exhibit "A"; or adopt Ordinance No. 92-54 as introduced
on November 23rd and introduce the proposed Ordinance No. _. set forth in Exhibit "C"
amending certain provisions of Chapter 14.17 and set for public hearing on January 11,
1993; or adopt Emergency Ordinance No. 92-54 with suggested changes as set forth inr
Exhibit "B".
At the City Council meeting of November 23,1992, the City Council introduced Ordinance
No. 92-54 as set forth in the attached Exhibit "A". Said ordinance -proposes to establish local
regulations addressing the design, installation, and maintenance of water efficient landscapes
as required by the State Legislature (AB 325). Ordinance 92-54 had previously been
reviewed by the Utilities Committee and The Irvine Company and was thought by staff to
adequately address the regulations contained in the Model Ordinance developed by the
State Department of Water Resources. Nonetheless, there were some remaining concerns
raised by the City Council, and the staff was further directed to meet with Council member
Hedges and the Utilities Committee to resolve these concerns prior to the December 14th
hearing date.
On November 24, 1992, staff from the Planning Department met with Council member
Hedges to address his concerns. The changes which resulted from that meeting arb set forth
in the attached Exhibit "B" and were subsequently -reviewed by the Utilities Committee on
December 2,1992, and approved. The net effect of the changes are to suggest goals for the
} TO: Citylouncil - 2 •
design, installation and maintenance of water efficient landscaping in conjunction with all
new construction projects including all previously exempted projects. There are no
mandatory requirements and, therefore, the compliance and enforcement procedures of the
Ordinance have been eliminated. In approving these changes, the Utilities Committee was
of the opinion that neither the State Legislature or the Department of Water Resources
were diligent in requiring uniform application of the law at the local level.
Considering these most recent changes, the Attorneys Office is of the opinion the document
as it now stands is not a legal Ordinance and would be difficult to defend as a good faith
effort by the City to comply with AB 325. To correct these deficiencies, the Attorneys
Office has prepared a third document (see attached Exhibit "C") containing amendments
which if adopted with Ordinance 92-54 as introduced on November 23rd, will result in an
Ordinance that complies with AB 325.
It should be explained that the proposed amendments included in Exhibit "O' involve the
deletion of Section 14.17.060 of the Ordinance which requires a certification of compliance
to be prepared for applicable landscape projects and the preparation of an irrigation audit.
Although staff recognizes that there may be some concern regarding the inclusion of these
provisions, it is staffs opinion that they are necessary to insure compliance with the other
provisions of the Ordinance in light of the fact that the City does not currently have
personnel with sufficient knowledge of landscape and irrigation design, to adequately
determine the compliance of submitted landscape and irrigation plans.

CITY OF NEWPORT BEACH
OFFICE OF THE CITY ATTORNEY
December 4, 1992
TO: Mayor and Members of City Council
FROM: Robin Flory, Assistant City Attorney
RE: Ordinance Adding Chapter 14.17 to the Newport Beach
Municipal Code Pertaining to the Installation of
Water Efficient Landscapes
This office has reviewed the proposed amendments to the
ordinance which was introduced at the last meeting of the City
Council. For the following stated reasons, this office recommends
that the City Council adopt the ordinance that was introduced on
November 23, 1992, along with the introduction of the attached
ordinance.
Assembly Bill 325 was adopted by the Legislature based upon
findings concerning the limited supply of water in the state, the
increasing demands for water, and a policy to promote the
conservation and efficient use of water. With those findings, the
Legislature set out provisions for the Department of Water
Resources to prepare and promote the use of a water efficient
landscape ordinance which local agencies could adopt. Although the
legislation does not require the local agencies to adopt the model
ordinance, or any specific provisions of the model ordinance, we
are required to adopt a water efficient landscape ordinance by
January 1, 1993 or adopt findings which state that a water
efficient landscape ordinance is unnecessary. If neither action is
taken, the model ordinance will automatically take effect on
January 11 1993 and shall be required to be enforced by the City in
the same force and effect as if it had been adopted by the City.
We are concerned that the Ordinance in its revised form does
not constitute an ordinance. By making an ordinance wholly
voluntary, the ordinance is in fact policy not law because there is
no obligation to comply with its provisions and no penalty for non-
compliance. In the event of a challenge, a court could rule that
the City did not comply with Assembly Bill 325. A result of a
successful challenge could be required enforcement of the model
ordinance.
We understand there is specific concerti over certain
provisions of ordinance No. 92-54 which require certification,
approval and design by licensed landscape architects. This
P
•
language is not required by the Legislation and may be deleted if
desired. Therefore attached to this memorandum is a proposed
ordinance which deletes these provisions.
RECOMMENDATION: It is recommended that the Council adopt
Ordinance No. 92-54 in the form and content of the ordinance
introduced at the meeting of November 23, 1992 and subsequently
introduced the attached Ordinance amending certain provisions of
Chapter 14.17 and set for public hearing at the January 11, 1993
meeting of City Council.

OFFICE OF THE CITY ATTORNEY
December 4, 1992
TO: Mayor and Members of City Council '
FROM: Robin Flory, Assistant City Attorney
RE: Ordinance Adding Chapter 14.17 to the Newport Beach
Municipal Code Pertaining to the Installation of
Water Efficient Landscapes
This office has reviewed the proposed amendments to the
ordinance which was introduced at the last meeting of the City
Council. For the following stated reasons, this office recommends
that the City Council adopt the ordinance that was introduced on
November 23, 1992, along with the introduction of the attached
ordinance.
Assembly Bill 325 was adopted by the Legislature based upon
findings concerning the limited supply of water in the state, the
increasing demands for water, and a policy to promote the
conservation and efficient use of water. With those findings, the
Legislature set out provisions for the Department of Water
Resources to prepare and promote the use of a water efficient
landscape ordinance which local agencies could adopt. Although the
legislation does not require the local agencies to adopt the model
ordinance, or any specific provisions of the model ordinance, we
are required to adopt a water efficient landscape ordinance by
January 1, 1993 or adopt findings which state that a water
efficient landscape ordinance is unnecessary. If neither action is
taken, the model ordinance will automatically take effect on
January 1, 1993 and shall be required to be enforced by the City in
the same force and effect as if it had been adopted by the City.
We are concerned that the Ordinance in its revised form does
not constitute an ordinance. By making an ordinance wholly
voluntary, the ordinance is in fact policy not law because there is
no obligation to comply with its provisions and no penalty for non-
compliance. In the event of a challenge, a court could rule that
the City did not comply with Assembly Bill 325. A result of a
successful challenge could be required enforcement of the model
ordinance.
We understand there is specific concern over certain
provisions of Ordinance No. 92-54 which require certification,
approval and design by licensed landscape architects. This
language is not required by the Legislation and may be deleted if
desired. Therefore attached to this memorandum is a proposed
Ordinance which deletes these provisions.
RECOMMENDATION: It is recommended that the Council adopt
Ordinance No. 92-54 in the form and content of the Ordinance
introduced at the meeting of November 23, 1992 and subsequently
introduced the attached Ordinance amending certain provisions of
Chapter 14.17 and set for public hearing at the January 11, 1993
meeting of City Council.

FROM: Planning Director, James D. Hewicker Q
SUBJECT: WEEKLY COUNCIL NEWSLETTER
PROPOSED WATER EFFICIENT LANDSCAPE ORDINANCE
At the City Council meeting of November 23, 1992, the City Council introduced Ordinance
No. 92-54 which proposes to establish local regulations addressing the design, installation,
and maintenance of water efficient landscapes as required by the State Legislature (AB
325). Ordinance 92-54 had previously been reviewed by the Utilities Committee and The
Irvine Company and was thought by staff to adequately address the regulations contained
in the model Ordinance developed by the State Department of Water Resources.
Nonetheless, there were some remaining concerns raised by the City Council, and the staff
was further directed to meet with Council member Hedges and the Utilities Committee to
resolve these concerns prior to the December 14th hearing date.
On November 24, 1992, staff from the Planning Department met with Council member
Hedges to address his concerns. The changes from that meeting were subsequently reviewed
by the Utilities Committee on December 2, 1992, and approved. The net effect of the
changes are to suggest goals for the design, installation and maintenance of water efficient
landscaping in conjunction with all new construction projects including all previously
exempted projects. There are no mandatory requirements and, therefore, the compliance
and enforcement procedures of the Ordinance have been eliminated. In approving these
changes, the Utilities Committee was of the opinion that neitlier•the State Legislature or the
Department of Water Resources were diligent in requiring uniform application of the law
at the local level.
Considering these most recent changes, the Attorney's Office is of the opinion the document
as it now stands is not a legal Ordinance and would be difficult to defend as a good faith
effort by the City to comply with AB 325. To correct these deficiencies, the Attorney's
Office is now working on a third document containing amendments which if adopted with
the Ordinance as introduced on November 23rd, will give everyone an Ordinance they can
be pleased with.

PLANNING DEPARTMENT
CITY OF NEWPORT BEACH
DATE: November 25, 1992
TO: Jeff Staneart, Utilities Director (Acting)
FROM: James D. Hewicker, Planning Director&
SUBJECT: Draft Water Efficient Landscape Ordinance
Attached is a copy of the Draft Water Efficient Landscape Ordinance which incorporates
the changes suggested by Councilman Hedges and which the City Council has requested the
Utilities Committee to review prior to the December 14, 1992 public hearing.
The net effect of the proposed changes are to suggest goals for the design, installation and
maintenance of water efficient landscaping in conjunction with all new construction projects
within the City including all previously exempted projects. The ordinance suggests that the
preparation of landscape plans, irrigation design plans, irrigation schedules, soil analysis and
maintenance schedules be considered, but it does not make such plans or schedules
mandatory or require that they be submitted to anyone. In addition, all compliance and
enforcement provisions have been eliminated.
Please let me know the date and time of the next meeting.

sprinkler head that holds water in the, system so it minimizes drainage from
the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation
system to the landscape.
D. "automatic controller" means a mechanical or solid state timer, capable
of operating valve stations which set the days and duration of a water
application.

pollution or contamination of the water supply that could result from the
reverse flow of water from the irrigation system.
F. "ecological restoration project" means a project where the site is
intentionally altered to establish a defined, indigenous, ecosystem.
G. "emitter" means drip irrigation fittings that slowly deliver water from
the system to the soil.
H. "established landscape" means the point at which plants in the

means treated or recycled waste water of a quality suitable for non -potable
uses such as landscape irrigation; not intended for human consumption.
Z. "reference evapotranspiration" or "Eto" means a standard measurement
of environmental parameters which affect the water use of plants. Eto is
given in inches per day, month, or year; as represented in Section 705, and is
an estimate of the evapotranspiration of a large field of four- 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.
AA. "rehabilitated landscape" means any relandscaping project that is done
in conjunction with an applicable project as set forth in Section 14.17.020 A,
that requires the issuance of a building permit or grading permit for the
construction of new structures or the rehabilitation of existing structures.

CITY OF NEWPORT BEACH
TO: Mayor and Members of the City Council
FROM: Planning Department64
SUBJECT: Proposed Water Efficient Landscape Ordinance
Request to initiate a proposed amendment to Title 14 of the Newport
Beach Municipal Code pertaining to the establishment of provisions
for the design, installation and maintenance of water efficient
landscapes.
Proposed Ordinance
Request to initiate a proposed amendment to Title 14 of the Newport Beach Municipal
Code pertaining to the establishment of provisions for the design, installation and
maintenance of water efficient landscapes.
Suggested Action
If desired, introduce the proposed Ordinance and schedule a public hearing for December
14, 1992
Background
At its meeting of November 9, 1992, the City Council reviewed a draft of the proposed
Water Efficient Landscape Ordinance at its afternoon Study Session. At that time, staff
presented a comparative summary of the City's proposed Ordinance relative to the State's
Model Water Efficient Landscape Ordinance. In light of the comments made by some of
the City Council members, it is important to stress that inasmuch as the provisions of the
proposed Ordinance apply primarily to commercial, industrial, institutional and -multi -family
projects containing more than 2,500 square feet of landscaping, the requirements of the
proposed Ordinance are not significantly different from the landscaping and irrigation design
efforts normally accomplished by a private developer. Therefore, the staff does not view
the proposed Ordinance as imposing an unreasonable or costly burden upon either private
or public projects within the City. The only additional cost that staff envisions would be for
the irrigation audit and the final field observation required for the Certification of
Compliance. This cost should be no more than a few hundred dollars.
Since the last City Council meeting, staff has met with a representative from the Irvine
Company who has suggested some changes to the subject Ordinance. For the most part, the
suggested changes provide language which gives a greater degree of flexibility relative to the
design of irrigation systems and the selection of appropriate irrigation equipment. It has
• 0
TO: City Council - 2
also been suggested that projects that exclusively use reclaimed water for landscape
irrigation should be exempt from the provisions of the Ordinance. Each of the suggested
changes are set forth as strike -out and underline revisions in the attached copy of the City's
proposed Ordinance.
Staff has not included a suggested change from the Irvine Company relative to the
elimination of the requirement for an irrigation audit as part of the certification compliance
process. The reason for not including this change is that staff has not had sufficient time
to fully review the necessity of the irrigation audit provision. However, staff will be
prepared to discuss this issue at the City Council meeting.

CITY OF NEWPORT BEACH
TO: Mayor and Members of the City Council
FROM: Planning Department64
SUBJECT: Proposed Water Efficient Landscape Ordinance
Request to initiate a proposed amendment to Title 14 of the Newport
Beach Municipal Code pertaining to the establishment of provisions
for the design, installation and maintenance of water efficient
landscapes.
Proposed Ordinance
Request to initiate a proposed amendment to Title 14 of the Newport Beach Municipal
Code pertaining to the establishment of provisions for the design, installation and
maintenance of water efficient landscapes.
Suggested Action
If desired, introduce the proposed Ordinance and schedule a public hearing for December
14, 1992.
Background
At its meeting of November 9, 1992, the City Council reviewed a draft of the proposed
Water Efficient Landscape Ordinance at its afternoon Study Session. At that time, staff
presented a comparative summary of the City's proposed Ordinance relative to the State's
Model Water Efficient Landscape Ordinance. In light of the comments made by some of
the City Council members, it is important to stress that inasmuch as the provisions of the
proposed Ordinance apply primarily to commercial, industrial, institutional and multi -family
projects containing more than 2,500 square feet of landscaping, the requirements of the
proposed Ordinance are not significantly different from the landscaping and irrigation design
efforts normally accomplished by a private developer. Therefore, the staff does not view
the proposed Ordinance as imposing an unreasonable or costly burden upon either private
or public projects within the City. The only additional cost that staff envisions would be for
the irrigation audit and the final field observation required for the Certification of
Compliance. This cost should be no more than a few hundred dollars.
Since the last City Council meeting, staff has met with a representative from the Irvine
Company who has suggested some changes to the subject Ordinance. For the most part, the
suggested changes provide language which gives a greater degree of flexibility relative to the
design of irrigation systems and the selection of appropriate irrigation equipment. It has
0
TO: City Council - 2
also been suggested that projects that exclusively use reclaimed water for landscape
irrigation should be exempt from the provisions of the Ordinance. Each of the suggested
changes are set forth as strike -out and underline revisions in the attached copy of the City's
proposed Ordinance. '
Staff has not included a suggested change from the Irvine Company relative to the
elimination of the requirement for an irrigation audit as part of the certification compliance
process. The reason for not including this change is that staff has not had sufficient time
to fully review the necessity of the irrigation audit provision. However, staff will be
prepared to discuss this issue at the City Council meeting.

INSTALLATION OF WATER EFFICIENT LANDSCAPES
The City Council of the City of Newport Beach does hereby ordain as follows:
SECTION 1: Findings, The City Council finds and declares as follows:
A. The Legislature of the State of California has adopted the Water
Conservation in Landscaping Act which requires cities and counties within the state to adopt
water efficient landscape ordinances which will promote the efficient use of water in
landscapes while respecting the economic, environmental, aesthetic, and lifestyle choices of
individuals and property owners.
B. The City Council's policy is to promote the conservation and efficient wse of
water within the City so as to prevent the waste of available water resources, and to apply
this policy to the design, installation and maintenance of certain landscapes within the City.
C. That the Department of Water Resources of the State of California, pursuant
to the requirements of the Water Conservation in Landscaping Act, has adopted a model
water efficient landscape ordinance and that the City Council has considered the model
ordinance in conjunction with the adoption of its own water efficient landscape ordinance.
SECTION2: Chapter 14.17 of the Newport Beach Municipal Code is adopted
to read:

establish reascnable procedures and standards for the design, installation, and maintenance
of water efficient landscapes in conjunction with new construction projects within the City
1
J
of Newport Beach to promote the conservation and efficient use of water within the City
and prevent the waste of available water resources.
14.17.005 Definitions. As used in this Chapter, the following terms shall
have the meanings indicated:
A. "anti -drain valve" or "check valve" means a valve located under a
sprinkler head that holds water in the system so it minimizes drainage from
the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation .
system to the landscape.
D. "automatic controllee means a mechanical or solid state timer, capable
of operating valve stations which set the days and duration of a water
application.

pollution or contamination of the water supply that could result from the
reverse flow of water from the irrigation system.
F. "ecological restoration project" means a project where the site is
intentionally altered to establish a defined, indigenous, ecosystem.
G. "emitter" means drip irrigation fittings that slowly deliver water from
the system to the soil.
H. "established landscape" means the point at which plants in the
landscape have developed roots into the sell adjacent to the root ball.
I. 'establishment period" means the first year after installing the plant
in the landscape.
I 'Estimated Total Water Use" 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.
2
9f
K "evapotranspiration" means the quantity of water evaporated from
adjacent soil surfaces and transpired by plants during a specific time.
L "flow rate" means the rate at which water flows through pipes and
valves (gallons per minute or cubic feet per second).

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.
N. "infiltration rate" means the rate of water entry into the soil expressed
�r
as a depth of water per unit of time (inches per hour).
O. "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 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.
P. "landscape Irrigation audit" means a process to perform site
inspections, evaluate irrigation systems, and develop efficient irrigation
schedules.
Q. 'landscaped area" means the entire parcel less the building footprint,
driveways, non -irrigated portions of parking lots, hardscapes - such as decks

March 5, 1993
Thank you for responding to the requirements of Assembly
Bill 325. We have received your material. According to AB 325,
the Water Conservation in Landscaping Act, the State Model Water
Efficient Landscape Ordinance automatically went into effect in
all communities that had not adopted their own ordinance or
issued findings that no ordinance was necessary by January 11
1993.
For your information, I have enclosed a list of the cities
and counties that have submitted documents. The list indicates
the general approach followed by each local agency: water
budget, turf limits, findings, point system, or another approach.
If a city or county is -not on this list, we have not received an
ordinance from them and assume they are administering the State
Model Ordinance.
For more specific information about local
region, we can provide hard copy reports or a
complete information on
more information or have

IMG
Irrigation Management Group
On January 1, 1993, State Assembly Bill 325, the landscape water
conservation law became effective, dictating cities and counties
to adopt a landscape water conservation ordinance. The model
ordinance contained in this law and similarly adopted local
ordinances requires calculations for annual water usage based on
the planting and irrigation designs submitted for ,proposed
projects.
Over the past several years, the principals of Irrigation
Management Group (IMG) have provided educational leadership to
public and private land management professionals and the "Green
Industry". Through their many lectures, presentations, and
training programs, IMG has emphasized an educational approach to
water resource management.
IMG has now developed ET Cale, a sophisticated, yet simple -to- use
software program to assist compliance officers, landscape
architects, and contractors with the requirements of new water
conservation ordinances.
You are cordially invited to attend one of our scheduled two-hour
seminars and demonstrations of ET CalcTM software at our Union City
office and training center. There is no charge for the seminar and
demonstration, but reservations are required as space is limited.
Currently, there is space available for the following dates and
times:

New Software Targets Water Budgets
In response to landscape water
conservation measures through-
out California, a new software
program called Er Caldm is now
available in Macintosh® format for
landscape professionals to use in
calculating accurate water budgets for
planting, irrigation, and landscape
management.
"The timing of this new program
couldn't be better," explained Richard
Sealana, partner at Irrigation Manage-
ment Group (IMG), the firm that
developed the software program.
"There is an immediate need to ;
prepare for water budgeting.
We feel that Er Caldm will
shorten the learning curve for
everyone needing to quan-
tify their landscape water
conservation efforts."
Up to now, landscape
architects and planners
have not had a compre-
ing landscape water
requirements at the design A
stage. Ef Caldm provides
that means. Considering
such factors as soil texture,
species water ratings, micro
climate conditions, density of
the landscape, and more,
designs can be quickly
evaluated for water use and
verified for compliance to avoid
expensive redrafting time.
Er CalOm has numerous reports for
compliance verification of local water
requirements as well as comprehensive
ordinances such as that provided under
state legislation AB 325 (the Water
Conservation in Landscaping Act)
effective January 1,1993.
Marsha Prillwitz, Landscape Program
Manager at the California Department
of Water Resources, who managed
development of the landscape model
ordinance commented,' ST Caldm is
one of the most comprehensive tools
available for estimating water use for
planning purposes:'
The name Er Caldm is derived from
evapotranspiration WD, the measure-
ment of water used by plants through
transpiration and evaporation and one
of the many factors included in the
product's calculations. In addition to
projecting accurate water use, Ef
CalcTm generates irrigation schedules
for various irrigation systems,
including drip and bubbler
applications.

14.17.005 Intent And Purpose. It is the purpose of this Chapter to
establish reasonable procedures and standards for the design, installation, and maintenance
of water efficient landscapes in conjunction with new construction projects within the City
of Newport Beach to promote the conservation and efficient use of water within the City
and prevent the waste of available water resources.
14.17.005 Definitions. As used in this Chapter, the following terms shall
have the meanings indicated:
A. "anti -drain valve" or "check valve" means a valve located under a
sprinkler head that holds water in the system so it minimizes drainage from
the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation
system to the landscape.
1
D. "automatic controller" means a mechanical or solid state timer, capable
of operating valve stations which set the days and duration of a water
application.
E. "backflow prevention device" means a safety device which prevents
pollution or contamination of the water supply that could result from the
reverse flow of water from the irrigation system.
F. "ecological restoration project" means a project where the site is
intentionally altered to establish a defined, indigenous, ecosystem.
G. "emitter" means drip irrigation fittings that slowly deliver water from
the system to the soil.
H. westablished landscape" means the point at which plants in the
landscape have developed roots into the soil adjacent to the root ball.
I. "establishment period" means the first year after installing the plant
in the landscape.
I "Estimated Total Water Use" 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.
K "evapotranspiration" means the quantity of water evaporated from
adjacent soil surfaces and transpired by plants during a specific time.
OA
L. "flow rate" means the rate at which water flows through pipes and
valves (gallons per minute or cubic feet per second).
M. "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.
N. "infiltration rate" means the rate of water entry into the soil expressed
as a depth of water per unit of time (inches per hour).
O. "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 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.
P. "landscape irrigation audit" means a process to perform site
inspections, evaluate irrigation systems, and develop efficient irrigation
schedules.
Q. "landscaped area" 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
3
calculation of the landscaped area. Areas dedicated to edible plants, such as
orchards or vegetable gardens are not included.
R. "lateral line" means the water delivery pipeline that supplies water to
the emitters or sprinklers from the valve.
S. "main line" means the pressurized pipeline that delivers water from
the water source to the valve or outlet.
T. "mulch" means any organic material such as leaves, bark, straw or
inorganic material such as decomposed granite other which is left loose or
applied to the soil surface to reduce evaporation.
U. "operating pressure" means the pressure at which a system of
sprinklers is designed to operate, usually indicated at the base of a sprinkler.
V. "overspray" means the water which is delivered beyond the landscaped
area, wetting pavements, walks, structures, or other non -landscaped areas.
W. "rain sensing device" means a system which automatically shuts off the
irrigation system when it rains.
X. "recreational area" means areas of active play or recreation such as
sports fields, school yards, picnic grounds, or other areas with intense foot
traffic.
Y. "recycled water," "reclaimed water," or "treated sewage effluent water"
means treated or recycled waste water of a quality suitable for non -potable
uses such as landscape irrigation; not intended for human consumption.
0
Z. "reference evapotranspiration" or "Eto" means a standard measurement
of environmental parameters which affect the water use of plants. Eto is
given in inches per day, month, or year as represented in Section 705, and is
an estimate of the evapotranspiration of a large field of four- 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.
AA. "rehabilitated landscape" means any relandscaping project that is done
in conjunction with an applicable project as set forth in Section 14.17.020 A,
that requires the issuance of a building permit or grading permit for the
construction of new structures or the rehabilitation of existing structures.
BB. "run off' 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.
CC. "soil moisture sensing device" means a device that measures the
amount of water in the soil.
DD. "soil texture" means the classification of soil based on the percentage
of sand, silt, and clay in the soil.
DD. "sprinkler head" means a device which sprays water through a nozzle.
EE. "static water pressure" means the pipeline or municipal water supply
pressure when water is not flowing.
9
FF. "station" means an area served by one valve or by a set of valves that
operate simultaneously.
GG. "turf' 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.
HH. "valve" means a device used to control the flow of water in the
irrigation system.
IL All terms not otherwise defined within this Chapter shall be defined in
accordance with such terms as defined in Chapter 20.87 of this Code.
14.17.020 Applicability.
A. The provisions contained within this chapter shall apply to :

and irrigation design for applicable projects shall comply with the following design
standards:
A. Landscape Design Plan Specifications. The landscape design plan shall be
drawn to scale and shall accurately and clearly identify:
1. Designated hydrozones.
2. Landscape materials, trees, shrubs, ground cover, turf, and other
vegetation. Planting symbols shall be clearly drawn and plants labeled by
botanical name, common name, container size, spacing, and quantities of each
group of plants indicated.
3. Property lines, easements, and street names.
4. Streets, driveways, walkways, and other paved areas.
5. Location, size and type of any underground utilities on the site.
6. Pools, ponds, water features, fences, and retaining walls.
7. Existing and proposed buildings and structures including elevation if
applicable.
7
0
8. Natural features including but not limited to rock outcroppings, existing
trees, shrubs that will remain.
9. Tree staking, plant installation, soil preparation details, and any other
applicable planting and installation details.
10. A calculation of the total landscaped area.
11. Designation of recreational areas.
B. Plant Selection and Grouping.
1. Plants having similar water use shall be grouped together in distinct
hydrozones.
2. Plants shall be selected appropriately based upon their adaptability to the
climatic, geologic, soil and topographical characteristics of the site. Protection
and preservation of native species and natural areas is encouraged. The
planting of trees is encouraged wherever it is consistent with the other
provisions of this Chapter.
3. Fire prevention needs shall be addressed in areas that are fire prone.
Information about fire prone areas and appropriate landscaping for fire safety
is available from the Newport Beach Fire Department.
C. Irrigation Design. All required landscape areas shall be equipped with a
permanently installed irrigation system which utilizes the most current and cost effective
irrigation technology so as to maximize the efficient use of water. Irrigation design shall
include the following design criteria:
M
L
CI
1. Runoff and Overspray. Soil types and infiltration rate shall be considered
when designing irrigation systems. All irrigation systems shall be designed to
avoid runoff, low head drainage, overspray, or other similar conditions where
water flows onto adjacent property, non -irrigated areas, walks, roadways, or
structures. Proper irrigation equipment and schedules, including features such
as repeat cycles, shall be used to closely match application rates to infiltration
rates therefore minimizing runoff. Special attention shall be given to avoid
runoff on slopes and to avoid overspray in planting areas and medians with
a width less than ten feet.
2. Equipment.
a. Water meters. Separate landscape water meters shall be
encouraged for all projects except for single family homes or any
project with a landscaped area of less than 5,000 square feet.
b. Controllers. Automatic control systems shall be required for all
irrigation systems and must be able to accommodate all aspects of the
design.
C. Valves. Where feasible, plants which require different amounts
of water shall be irrigated by separate valves. If one valve is used for
a given area, efforts shall be made to insure that plants with similar
water use are used in that area. Anti -drain (check) valves shall be
installed in strategic points to minimize or prevent low -head drainage.
W,
d. Sprinkler heads. Heads and emitters shall have consistent
application rates within each control valve circuit. Sprinkler heads

the city block bounded by W. Bay Ave.,
Dist

(89)
Report from the Public Works Director.
The City Clerk advised that after the
agenda was printed, a letter was
received from the Newport Harbor Yacht
Club in support of the proposed
assessment district.
The Public Works Director stated that
the proposed assessment district was
initiated by petitions received from
roperty owners representing
a proximately 95% of the area in
qu stion. He referenced the final cost
fig res contained in the Engineer's
Repo t noting that the prgliminary cost
figur s have been reduced and the
revise assessments reflect that a
typical 30 foot lot will be $4,112.70,
and that he Newport Harbor Yacht Club's
proposed assssment has been reduced
proportion tely. There will be one
additional ost to the property owners
for the co version of the service
connections w ich must be arranged for
individually. o date, there have been
no protests ceived opposing the
formation of thi assessment district.
He also recommend d that this district
not be modified to ttelude the 600 block
of West Bay Avenue, such modification
could delay the distr ct by one-year and
would not save any c sts. There are
other underground%% stricts in the
planning stages on the P insula, and it
was felt by staff that he 600 block
could be combined with ne of those
districts.
Burleigh Brewer, Vice Co odors of
Newport Harbor Yacht Club, add ssed the
Council in support of the reposed
assessment district and the evised
Engineer's Report. He also state that
they were in concurrence with the
recommendation that the 600 bloc of
West Bay Avenue not be included in t is
assessment district.

this policy to the design, installation and maintenance of certain landscapes within the City.
C. That the Department of Water Resources of the State of California, pursuant
to the requirements of the Water Conservation in Landscaping Act, has adopted a model
water efficient landscape ordinance and that the City Council has considered the model
ordinance in conjunction with the adoption of its own water efficient landscape ordinance.
SECTION 2: Chapter 14.17 of the Newport Beach Municipal Code is adopted
to read:

the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation
system to the landscape.
D. "automatic controller" means a mechanical or solid state timer, capable
of operating valve stations which set - the days and duration of a water
application.

the system to the soil.
H. westablished landscape" means the point at which plants in the
landscape have developed roots into the soil adjacent to the root ball.
I. "establishment period" means the first year after installing the plant
in the landscape.
I "Estimated Total Water Use" means the annual total amount of water

have the meanings indicated:
A. "anti -drain valve" or "check valve" means a valve located under a
sprinkler head that holds water in the system so it minimizes drainage from
the lower elevation sprinkler heads.
B. "application rate" means the depth of water applied to a given area,
usually measured in inches per hour.
C. "applied water" means the portion of water supplied by the irrigation
system to the landscape.
D. "automatic controller" means a mechanical or solid state timer, capable
of operating valve stations which set the days and duration of a water
application.

no protests received oppo ing the
formation of this assessment istrict.
He also recommended that this istrict
not be modified to include the 6 0 block
of West Bay Avenue, as such modif cation
could delay the district by one-y r and
would not save any costs. Ther are

TO: California Cities and Counties and Others Interested in
Assembly Bill 325: The Water Conservation in Landscaping Act
California's Model Water Efficient Landscape Ordinance, as
required by Assembly Bill 325, was officially adopted by the Depart-
ment and filed with the Secretary of State, July 31, 1992. A copy of
the final version of the Ordinance is enclosed for your information.
No substantive changes were made from the January 17, 1992 version.
The State Model Ordinance will automatically go into effect
January 1, 1993 in all California cities and counties that do not
adopt their own local water efficient landscape ordinance, having
considered the provisions of the State Model Ordinance; or issued
findings that no ordinance is necessary.
If you decide to issue findings or adopt an ordinance other than
the State Model Ordinance, please send a copy of your action to me
upon adoption, or no later than January 31, 1993, as specified in the
law. My address is:
Department of Water Resources
Post Office Box 942836
Sacramento, California 94236-0001
Information about local ordinances will be entered into a data
base and provided to people upon request. The Department will report
to the Legislature summarizing the status of water efficient landscape
ordinances adopted by local agencies by July 1, 1993.
If you would like to attend an AB 325 workshop, please complete
the enclosed "Survey" and return it to me. This will help us provide
the information you need most to adopt, administer, and implement
AB 325. Thank you for your active participation and support of this

490. Purpose.
(a) The State Legislature has found:
4
(1) that the limited supply of state waters are subject to ever
Increasing demands;
(2) that California's economic 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.

491. Definitions.
F9
The words used in this ordinance have the meaning set forth below:
(a) "anti -drain valve" or "check valve" means a valve located
under a sprinkler head to hold water in the system so it minimizes
drainage from the lower elevation sprinkler heads.
(b) "application rate" means the depth of water applied to a
given area, usually measured in inches per hour.
(c) "applied water" means the portion of water supplied by the
irrigation system to the landscape.
(d) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to set the days and length
of time of a water application.
(e) "backflow 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 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
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.) .
(g) "ecological restoration project" means a project where the
site is intentionally altered to establish a defined, indigenous,
historic ecosystem.
(h) 'effective precipitation" or "usable rainfall' 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.
(1) 'emitter" means drip irrigation fittings that deliver water
slowly from the system to the soil,
(j) 'established landscape" means the point at which plants in
the landscape have developed roots into the soil adjacent to the root
ball.
(k) 'establishment period" means the first year after installing
the plant in the landscape.
(1) "Estimated Applied Water Use" means the portion of the
Estimated Total Water Use that 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, as
referenced in Section 492 (c) (3).
(m) "Estimated Total Water Use" 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, as described
In Section 492 (a) (4).
(n) "ET adjustment factor" 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.
0 0
7
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).
(o) "evapotranspiration" 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 per 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
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.
H
(u) "landscaped area" 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.
(v) "lateral line" means the water delivery pipeline that supplies
water to the emitters or sprinklers from the valve.
(w) "main line" means the pressurized pipeline that delivers
water from the water source to the valve or outlet.
(x) "Maximum Applied Water Allowance" means, for design
purposes, the upper limit of annual applied water for the established
landscaped area as specified In Section 492 (c) (2). 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 Allowance.
(y) "mined -land reclamation projects" means any surface
mining operation with a reclamation plan approved in accordance
with the Surface Mining and Reclamation Act of 1975.
(z) "mulch" means any material such as leaves, bark, straw or
other materials left loose and applied to the soil surface for the
beneficial purpose of reducing evaporation .
(as) "operating pressure" means the pressure at which a system
of sprinklers is designed to operate, usually indicated at the base of
a sprinkler.
(bb) "overhead sprinkler Irrigation systems" means those
with high flow rates (pop -ups, impulse sprinklers, rotors, etc.)
(cc) "overspray" means the water which is delivered beyond the
landscaped area, wetting pavements, walks, structures, or other non -
landscaped areas.
0 0
(dd) "plant factor" means a factor 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 during 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 "treated
sewage effluent water" means treated or recycled waste water
of a quality suitable for nonpotable uses such as landscape
irrigation; not intended for human consumption.
(ii) "reference evapotranspiration" or "ETo" means a standard
measurement of environmental parameters which affect the water
use of plants. ETo is given in inches per day, month, or year as
represented in Section 495, and is an estimate of the
evapotranspiration of a large field of four- 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.
(jj) "rehabilitated landscape" means any relandscaping project
that requires a permit.
we
(kk) "run off' 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.
(II) "soil moisture sensing device" means a device that
measures the amount of water in the soil.
(mm) "soil texture" means the classification of soil based on the
percentage of sand, silt, and clay in the soil.

(2) The Maximum Applied Water Allowance
(A) A project's Maximum Applied Water Allowance shall be
calculated 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:
(1) PROJECT SITE ONE: Landscaped area of 50,000 sq. ft. in 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: 1,264,800/748=1,691)
(ii) PROJECT 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 1,160 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.
17
(3) Estimated Applied Water Use
(A) The Estimated Applied Water Use shall not exceed the Maximum
Applied Water Allowance.
(B) A calculation of the Estimated Applied Water Use shall be
submitted with the Landscape Documentation Package. It may be
calculated by summing the amount of water recommended in the
irrigation schedule.
(4) Estimated Total Water Use
(A) A calculation of the Estimated Total Water Use shall be
submitted with the Landscape Documentation Package. The
Estimated Total Water Use may be calculated by summing the
amount of water recommended in the irrigation schedule and adding
any amount of water expected from effective precipitation (not to
exceed 25 percent of the local annual mean precipitation) or may be
calculated from a formula such as the following:
The Estimated Total Water Use for the entire landscaped area, equals
the sum of the Estimated Water Use of all hydrozones in that
landscaped area.
EWU (hydrozone) = (ETo) (PF) (HA) (.62)
(IE)
EWU (hydrozone) = Estimated Water Use (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
PF = plant factor
HA = hydrozone area (square feet)
(.62) = conversion factor
IE = irrigation efficiency
ilm
(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
A landscape design plan meeting the following requirements shall be
submitted as part of the landscape documentation package.

Assembly Bill No. 325 i{
CHAPTER 1145
An act to add Article 10.8 (commencing with Section 65590) to
Chapter 3 of Division 1 of Title 7 of the Government Code, relating
to water conservation.
[Approved by Governor September 20, 1990. Filed with
Secretary of State September 21, 1990.]
LEGISLATIVE COUNSEL'S DIGEST
AB 325, Clute. Water conservation: landscaping ordinance.
• (1) Under existing law, local agencies are not required to adopt
ordinances concerning landscape water conservation.
This bill would require the Department of Water Resources by
February 1,1991, to appoint an advisory task force to work with the
department in the drafting of a model water efficient landscape
ordinance and to submit the recommended ordinance to the
department by May 1, 1991. The bill would require the department
by January 1, 1992, after holding a public hearing, based on
recommendations of the task force, to adopt a model local water
efficient landscape ordinance which each local agency, as defined,
may adopt. The bill would provide that if any local agency has not
adopted a water landscape ordinance or findings, based on specified
factors, that no ordinance is necessary, by January 1, 1993, the model
ordinance shall take effect and shall be enforced by that local agency
and have the same force and effect as if adopted by that local agency.
The bill would require each local agency, not later than January 31,
1993, to file with the department a copy of the water efficient
landscape ordinance adopted, or the findings which state that no
• ordinance is necessary, thereby imposing a state -mandated local
program.
The bill would require the department to report to the Legislature
on the status of these local ordinances by July 1, 1993.
The bill would require the model ordinance to contain specified
provisions and would specify related matters.
The bill would make legislative findings and declarations and
would declare legislative intent.
(2) 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.

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 economic 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.

491. Definitions.
The words used in this ordinance have the meaning set forth below:
(a) "anti -drain valve" or 'check valve" means a valve located
under a sprinkler head to hold water in the system so it minimizes
drainage from the lower elevation sprinkler heads.
(b) "application rate" means the depth of water applied to a
given area, usually measured in inches per hour.
(c) "applied water" means the portion of water supplied by the
irrigation system to the landscape.
(d) "automatic controller" means a mechanical or solid state
timer, capable of operating valve stations to set the days and length
of time of a water application.
(e) "backflow prevention device" means a safety device used to
prevent pollution or contamination of the water supply due to the

LA = Landscaped Area (square feet)
0.62 = conversion factor (to gallons per square foot)
(6) Two example calculations of the Maximum Applied Water
Allowance are:
(i) PROJECT SITE ONE: Landscaped area of 50,000 sq. ft. in 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: 11264,800/748=1,691)
(il) PROJECT SITE TWO: Landscaped area of 60,000 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 1,160 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

. Estimated Total Water Use may be calculated by summing the
amount of water recommended in the irrigation schedule and adding
any amount of water expected from effective precipitation (not to
exceed 25 percent of the local annual mean precipitation) or may be
calculated from a formula such as the following:
The Estimated Total Water Use for the entire landscaped area equals
the sum of the Estimated Water Use of all hydrozones in that
landscaped area.
EWU (hydrozone) = (ETo) (PF) (HA) (.62)
(IE)
EWU (hydrozone) = Estimated Water Use (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
