FROM: OFFICE OF THE CITY CLERK
SUBJECT: SECOND READING OF ORDINANCE NO. 1376 -CODE AMENDMENT 09-007:
WATER EFFICIENT LANDSCAPE ORDINANCE
SUMMARY:
In 2006, Governor Schwarzenegger signed Assembly Bill 1881, amending the Water
Conservation in Landscaping Act (Act). The bill added two new requirements: 1) the California
Department of Water Resources (DWR) is to update the current Model Water Efficient
Landscape Ordinance; and 2) each city and county must either comply with the final State
ordinance or may update its Landscape Ordinance by January 1, 2010, so that it is "at least as
effective as" the State's updated Model Ordinance. In response to the new landscape water
efficiency requirements, a stakeholder group was formed under the leadership of the Municipal
Water District of Orange County (MWDOC) and the Orange County Division of the League of
California Cities (the Division.) The stakeholder group developed alocally-crafted Orange
County Model Water Efficient Landscape Ordinance (OC Model) and Guidelines that will meet
the "at least as effective as" requirement of state law, minimize the complexity and cost of
compliance, and provide consistency between local jurisdictions. Proposed Ordinance No.
1376 is consistent with the OC Model.
The cornerstone of the OC Model Ordinance and Guidelines is aself-certification process that
will streamline the permitting process and reduce costs for applicants and local agencies.
Pursuant to the proposed ordinance, certain new and rehabilitated landscapes will be required
to be water efficient based on the criteria in the Guidelines.
RECOMMENDATION:
Have second reading by title only and adoption of Ordinance No. 1376 (roll call vote).
FISCAL IMPACT:
None
BACKGROUND:
On November 17, 2009, the City Council had first reading by title only and introduction of the
following Ordinance:

ORDINANCE NO. 1376
AN ORDINANCE OF THE CITY COUNCIL, OF THE CITY OF TUSTIN, ADDING
CHAPTER 7 OF ARTICLE 9 OF THE TUSTIN CITY CODE REGARDING WATER
EFFICIENT LANDSCAPES.
The City Council of the City of Tustin does hereby ordain as follows:
Section I. The City Council finds and determines as follows:
A. That the proposed amendment to the Tustin City Code is necessary to comply with the
requirements of Assembly Bill 1881 and the State Model Water Efficient Landscape
Ordinance adopted by the State Legislature in 2006.
B. That Assembly Bill 1881 requires the California Department of Water Resources (DWR)
to update the original Model Water Efficient Landscape Ordinance and requires cities and
counties to update local landscape ordinances so that they are "at least as effective as"
DWR's updated Model Ordinance by January 1, 2010.
C. That the State Legislature has found that:
(1) The waters of the State are of limited supply and are subject to ever increasing
demands;
(2) The continuation of California's economic prosperity is dependent on the
availability of adequate supplies of water for future uses;
(3) It is the policy of the State to promote the conservation and efficient use of water
and to prevent the waste of this valuable resource;
(4) Landscapes are essential to the quality of life in California by providing areas for
active and passive recreation and as an enhancement to the environment by
cleaning air and water, preventing erosion, offering fire protection, and replacing
ecosystems lost to development;
(5) Landscape design, installation, maintenance, and management can and should be
water efficient; and
(6) Article X, Section 2 of the California Constitution specifies that the right to use
water is limited to the amount reasonably required for the beneficial use to be
served, and the right does not and shall not extend to waste or unreasonable
method of use of water.
D. That the Municipal Water District of Orange County and the Orange County Division of
the League of California Cities formed a stakeholder working group that developed a
locally crafted Orange County Model Efficient Landscape Ordinance that will meet the
"at least as effective as" requirement of state law, minimize the complexity and cost of
compliance, and provide consistency between local jurisdictions.
E. That Orange County has an established, large reclaimed water infrastructure system.
Ordinance 1376
Page 2
F. That allocation-based and tiered water rate structures allow public agencies to document
water use in landscapes.
G. That incentive-based water use efficiency programs have been actively implemented
within Orange County since before 1991.
H. That current local design practices in new landscapes typically achieve the State Model
Water Efficient Landscape Ordinance water use goals.
I. That all water services within the City are metered.
J. That Orange County is a leader in researching and promoting the use of smart automatic
irrigation controllers with more than 4,500 installations as of June 2009.
K. That all new irrigation controllers sold after 2012 within Orange County will be smart
controllers.
L. That landscape plan submittal and review has been a long standing practice in Tustin.
M. That the average rainfall in Orange County is approximately 12 inches per year.
N. That the local water purveyors serving the City of Tustin are implementing tiered-rate
billing, budget-based tiered-rate billing and/or enforcement of water waste prohibitions
for all existing metered landscaped areas throughout their service areas, which include
the City of Tustin in its entirety.
O. That the purpose of the proposed Water Efficient Landscape Ordinance is to establish an
alternative model acceptable under AB 1881 as being at least as effective as the State
Model Water Efficient Landscape Ordinance in the context of conditions in the City in
order to:
(1) Promote the benefits of consistent landscape ordinances with neighboring local
and regional agencies;
(2) Promote the values and benefits of landscapes while recognizing the need to
invest water and other resources as efficiently as possible;
(3) Establish a structure for planning, designing, installing, and maintaining and
managing water efficient landscapes in new construction and rehabilitated
projects;
(4) Establish provisions for water management practices and water waste prevention
for existing landscapes;
(5) Use water efficiently without waste by setting a Maximum Applied Water
Allowance as an upper limit for water use and reduce water use to the lowest
practical amount; and
(6) Encourage the use of economic incentives that promote the efficient use of water,
such as implementing abudget-based tiered-rate structure.
Ordinance 1376
Page 3
P. That proposed Ordinance No. 1376 is consistent with the Orange County Model Water
Efficient Landscape Ordinance developed under the guidance of the Orange County
Division, League of California Cities and the Municipal Water District of Orange
County.
Q. That proposed Ordinance No. 1376 is exempt from environmental review under the
California Environmental Quality Act ("CEQA") (California Public Resources Code
Section 21000 et seq.), because pursuant to State CEQA Regulation 15307 (14 Cal. Code
Regs., § 15307), this Ordinance is covered by the CEQA Categorical Exemption for
actions taken to assure the maintenance, restoration, enhancement, or protection of a
natural resource where the regulatory process involves procedures for protection of the
environment. The adoption of this Ordinance will result in the enhancement and
protection of water resources in the City, and will not result in cumulative adverse
environment impacts. It is therefore exempt from the provisions of CEQA.
R. That the proposed code amendment is consistent with the Tustin General Plan in that it
complies with the following goal and policy:
Goa14: Protect water quality and conserve water supply.
Policy 5.3: Conserve imported water by requiring water conservation techniques,
water conserving appliances, and drought-resistant landscaping.
Section II. Article 9 of the Tustin City Code is hereby amended as follows:
Chapter 7 is hereby added in its entirety to Article 9 of the Tustin City Code to read as follows:

9706 -DEFINITIONS
The following terms as used in this chapter shall have the respective meanings as set forth except
when the context clearly indicates otherwise.
"Applied water" means the portion of water supplied by the irrigation system to the landscape.
"Budget-based tiered-rate structure" means tiered or block rates for irrigation accounts charged
by the retail water agency in which the block definition for each customer is derived from lot size
or imgated area and the evapotranspiration requirements of landscaping.
"Ecological restoration project" means a project where the site is intentionally altered to establish
a defined, indigenous, historic ecosystem.
"Estimated Applied Water Use" means the average annual total amount of water estimated to be
necessary to keep plants in a healthy state, calculated as provided in the Guidelines. It is based on
the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and
the relative irrigation efficiency of the irrigation system.
"ET adjustment factor" or "ETAF" is equal to the plant factor divided by the irrigation efficiency
factor for a landscape project, as described in the Guidelines. The ETAF is calculated in the
context of local reference evapotranspiration, using site-specific plant factors and irrigation
Ordinance 1376
Page 6
efficiency factors that influence the amount of water that needs to be applied to the specific
landscaped area.
A combined plant mix with asite-wide average plant factor of 0.5 (indicating a moderate water
need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) _
(0.5/0.71), which is the standard of water use efficiency generally required by this Water Efficient
Landscape Ordinance and the Guidelines, except that the ETAF for a special landscape area shall
not exceed 1.0.
"Guidelines" refers to the Guidelines for Implementation of the Water Efficient Landscape
Ordinance, as adopted by the City, which describes procedures, calculations, and requirements for
landscape projects subject to this Water Efficient Landscape Ordinance.
"Hardscapes" means any durable material or feature (pervious and non-pervious) installed in or
around a landscaped area, such as pavements or walls. Pools and other water features are
considered part of the landscaped area and not considered hardscapes for purposes of this Water
Efficient Landscape Ordinance.
"Homeowner installed landscape" means any landscaping either installed by a private individual
for a single family residence or installed by a licensed contractor hired by a homeowner. A
homeowner, for purposes of this ordinance, is a person who occupies the dwelling he or she
owns. This definition excludes speculative homes, which are not owner-occupied dwellings and
which are subject under this ordinance to the requirements applicable to developer-installed
residential landscape projects.
"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 average irrigation
efficiency for purposes of this Water Efficient Landscape Ordinance is 0.71. Greater irrigation
efficiency can be expected from well designed and maintained systems.
"Landscaped area" means all the planting areas, turf areas, and water features in a landscape
design plan subject to the Maximum Applied Water Allowance and Estimated Applied Water Use
calculations. The landscaped area does not include footprints of buildings or structures,
sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non-
pervious hardscapes, and other non-irrigated areas designated for non-development (e.g., open
spaces and existing native vegetation).
"Landscape contractor" means a person licensed by the State of California to construct, maintain,
repair, install, or subcontract the development of landscape systems.
"Landscape Documentation Package" means the documents required to be provided to the City
for review and approval of landscape design projects, as described in the Guidelines.
"Landscape project" means total area of landscape in a project, as provided in the definition of
"landscaped area," meeting the requirements under Section 1.1 of this Water Efficient Landscape
Ordinance.
"Local agency" means a city or county, including a charter city or charter county, that is
authorized by the City to implement, administer, and/or enforce any of the provisions of the
Water Efficient Landscape Ordinance on behalf of the City. The local agency may be responsible
for the enforcement or delegation of enforcement of this Water Efficient Landscape Ordinance
Ordinance 1376
Page 7
including, but not limited to, design review, plan check, issuance of permits, and inspection of a
landscape project.
"Local water purveyor" means any entity, including a public agency, city, county, or private
water company that provides retail water service.
"Maximum Applied Water Allowance" or "MAWA" means the upper limit of annual applied
water for the established landscaped area as specified in Section 2.2 of the Guidelines. 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.
"New construction" means, for the purposes of this Water Efficient Landscape Ordinance, a new
building with a landscape or other new landscape such as a park, playground, or greenbelt
without an associated building.
"Non-pervious" means any surface or natural material that does not allow for the passage of
water through the material and into the underlying soil.
"Pervious" means any surface or material that allows the passage of water through the material
and into the underlying soil.
"Permit" means an authorizing document issued by the City for new construction or rehabilitated
landscape.
"Plant factor" or "plant water use factor" is a factor, when multiplied by ETo, that estimates the
amount of water needed by plants. For purposes of this Water Efficient Landscape Ordinance, the
plant factor range for low water use plants is 0 to 0.3; the plant factor range for moderate water
use plants is 0.4 to 0.6; and the plant factor range for high water use plants is 0.7 to 1.0. Plant
factors cited in this Water Efficient Landscape Ordinance are derived from the Department of
Water Resources 2000 publication "Water Use Classification of Landscape Species."
"Recycled water" or "reclaimed water" means treated or recycled waste water of a quality
suitable for non-potable uses such as landscape irrigation and water features. This water is not
intended for human consumption.
"Reference evapotranspiration" or "ETo" means a standard measurement of environmental
parameters which affect the water use of plants. ETo is given expressed in inches per day, month,
or year as represented in Appendix A of the Guidelines, and is an estimate of the
evapotranspiration of a large Eeld 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.
"Rehabilitated landscape" means any re-landscaping project that meets the applicability criteria
of Section 9702a, where the modified landscape area is greater than 2,500 square feet, is 50% of
the total landscape area, and the modifications are planned to occur within one year.
"Smart automatic irrigation controller" means an automatic timing device used to remotely
control valves that operate an irrigation system and which schedules irrigation events using either
evapotranspiration (weather-based) or soil moisture data.
Ordinance 1376
Page 8
"Special landscape area" means an area of the landscape dedicated solely to edible plants such as
orchards and vegetable gardens, areas irrigated with recycled water, water features using recycled
water, and areas dedicated to active play such as parks, sports fields, golf courses, and where turf
provides a playing surface.
"Turf ' means a ground cover surface of mowed grass. 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.
"Valve" means a device used to control the flow of water in an irrigation system.
"Water feature" means a design element where open water performs an aesthetic or recreational
function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and
swimming pools (where water is artificially supplied). The surface area of water features is
included in the high water use hydrozone of the landscaped area. Constructed wetlands used for
on-site wastewater treatment, habitat protection or storm water best management practices that
are not irrigated and used solely for water treatment or storm water retention are not water
features and, therefore, are not subject to the water budget calculation.
Section III. The Guidelines for Implementation of the City of Tustin Water Efficient Landscape
Ordinance is hereby incorporated by reference.
Section IV. Ordinance No. 1099 is hereby repealed in its entirety.
Section V. If any section, subsection, sentence, clause, phrase or portion of this ordinance is for any
reason held out to be invalid or unconstitutional by the decision of any court of competent jurisdiction,
such decision shall not affect the validity of the remaining portions of this ordinance. The City Council of
the City of Tustin hereby declares that it would have adopted this ordinance and each section, subsection,
clause, phrase or portion thereof irrespective of the fact that any one or more sections, subsections,
sentences, clauses, phrases, or portions be declared invalid or unconstitutional.
