TITLE: Water Efficient Landscape Ordinance Amendment (NBMC Chapter
14.17)
ABSTRACT:
An amendment to Chapter 14.17 of the Newport Beach Municipal Code (Water Efficient
Landscaping Ordinance) and the accompanying Design Standards resulting from
Governor Brown's Drought Executive Order. The proposed documents comply with the
requirement that local jurisdictions adopt an ordinance "at least as effective as" the
State's Model Ordinance for water efficient landscaping. The ordinance requires the use
of plantings consistent with the local climate and modern irrigation technology to ensure
effective use of water.
RECOMMENDATION:
a) Find that the adoption of Code Amendment No. CA2015-001 is not subject to the
California Environmental Quality Act (CEQA) pursuant to Section 15307, Class 7
(Actions by Regulatory Agencies for the Protection of Natural Resources); and
b) Introduce Ordinance No. 2015-34, An Ordinance of the City Council of the City of
Newport Beach, California, Amending Chapter 14.17 of Title 14 of the Newport
Beach Municipal Code in its Entirety Pertaining to Regulations Required for Water
Efficient Landscaping (PA2015-169), and pass to second reading on January 26,
2016.
FUNDING REQUIREMENTS:
There is no direct fiscal impact related to this item.

DISCUSSION:
This code amendment originally appeared on the City Council's agenda for introduction
on November 24, 2015. Following the meeting staff discovered an error in the definition
of ET Adjustment factor and identified several inconsistencies carried into the City's
ordinance from the revised Orange County (OC) Model ordinance. Staff also clarified
several technical definitions with Metropolitan Water District of Orange County
(MWDOC) staff, who led the effort to revise the OC Model ordinance. As a result,
changes were made to ensure the revised ordinance and the associated Design
Guidelines are internally consistent. Formatting and referencing were also improved.
The overall applicability and implementation of the regulations did not change in any
substantive way. The ordinance is consistent with the OC Model and meets the criteria
for being "at least as effective as" the State Model Ordinance.
Pursuant to Charter Section 412, the proposed ordinance is required to be re -introduced
because of the revisions. Should the ordinance be introduced January 12, 2016 and
adopted on January 26, 2016 the State deadline to adopt a local ordinance when using
a regional model (OC Model) will be met.
Historical Background
In 2006, Governor Schwarzenegger signed Assembly Bill 1881 (Laird, Water
Conservation) amending the Water Conservation in the Landscape Act (Act). The bill
included two requirements: 1) Department of Water Resources (DWR) was to update
the original Model Water Efficient Landscape Ordinance; and 2) cities and counties
were required to adopt local landscape ordinances by January 1, 2010 which were "at
least as effective as" DWR's updated Model Ordinance. Due to the new "at least as
effective as" clause, meeting the requirements of AB 1881 resulted in significant
changes to most landscape ordinances in Orange County, including Newport Beach's
regulations.
Newport Beach Chapter 14.17 (Water Efficient Landscaping)
In January 2010 the City Council approved the amendments to Chapter 14.17 (Water
Efficient Landscaping) and adopted by reference the accompanying Design Standards.
The Design Standards include the requirements for the Landscape Documentation
package which is comprised of the landscape plans (irrigation plans, planting plans,
grading plans, etc.) water use calculations, and certification forms.
Governor's 2015 Executive Order
As a response to the ongoing statewide drought, Governor Brown signed the Drought
Executive Order on April 1, 2015. The order directed a broad range of water

conservation actions related to reduction of overall use, agricultural use, fire protection
and many other aspects of water usage. The order also directed the California
Department of Water Resources to once again update the State's Model Efficient
Landscape Ordinance. The revised model ordinance was adopted on September 15,
2015 (Attachment D).
Orange County Model and NBMC Chapter 14.17 Update
Similar to 2010, MWDOC led the effort to update the 2010 OC Model. The goal was to
revise the locally written OC Model that would meet the "at least as effective as"
requirement of state law, minimize the complexity and cost of compliance, and provide
consistency between local jurisdictions. Staff has revised the City's regulations to be
consistent with the updated OC Model (Attachment A). Since the City is using the
regional OC Model, state law requires the revised City regulations be adopted by
February 1, 2016. The OC Model is included as Attachment E.
The main goal of the revised regulations is increased water savings for new
construction through:
• More efficient irrigation systems
• Limiting the turf/grass area
• On-site stormwater capture
• Use of greywater
The notable changes to the requirements and standards are:
• The landscape area thresholds have been reduced to 500 square feet.
Landscaped areas that exceed 500 square feet will require compliance with the
amended ordinance.
• A Prescriptive Compliance Option, a check list approach, has been added to
simplify compliance for some smaller projects subject to the new requirements.
• The Evapotranspiration Table is expanded from three locations in Orange County
to at least one for each city and five different locations are included for Newport
Beach.
• A new prohibition on turf/grass in street medians and parkways for new projects.
• Clarified and expanded definitions of technical terms used in the Ordinance and
Design Standards.
• A Simplified Water Efficient Landscape Worksheet to calculate the Estimated
Total Water Use and Maximum Applied Water Allowance.
• Annual implementation and compliance reporting to the Department of Water
Resources. The City will be required to submit a report on an annual basis.

landscaping and irrigation is installed in accordance with approved plans.

Potential Effects of the New Requirements to Property Owners
New Construction and New Landscape Projects
The new regulations will require a higher number of new construction projects to submit
a Landscape Documentation Package and to comply with the standards. Under the
current regulations, the majority of new commercial projects that exceed the 2,500
square -foot landscape threshold are required to submit a Landscape Documentation
Package as part of the plan check/building permit process. Staff expects that the
amended 500 square -foot threshold will be exceeded by nearly all new commercial
projects.

By contrast, very few residential projects exceed the current 5,000 square -foot
landscape threshold. Staff expects a significant increase in the number of residential
projects that will be subject to the revised ordinance.
Landscape Rehabilitation (Replacement) Projects
Contrary to new landscape projects, replacement projects will remain exempt from the
ordinance as long as the replacement plantings have equal or lower water needs and
the irrigation system is designed, operable and programmed to comply with the City's
water conservation regulations. This essentially allows property owners to replace
existing landscaping, including turf/grass, with what they currently have.
Prescriptive Compliance Option — An Easier Alternative
Although more projects will be subject to the regulations, the City's draft ordinance
provides a less burdensome option, specifically the Prescriptive Compliance Option
(PCO). The PCO is available to projects with 2,500 square feet or less of landscape
area and which adhere to the specific plant materials requirements and irrigation system
requirements. Notable among these is the requirement to use climate adapted plants
and to allow only 25% of the area as turf/grass. Although the PCO still requires the
submittal of a Landscape Documentation Package, the required information is much
less than the regular requirements and the plans are not required to be prepared by a
certified landscape professional (See Appendix H of Attachment B).
Residential Projects — Where Will These New Standards Likely Apply?
There will be occasions where rehabilitation projects may be required to adhere to the
new standards. However, ordinance compliance will most often be associated with new
construction which includes the demolition and construction of new single family or
duplex homes. Staff performed an analysis and found that the majority of residential lots
within the City would likely be subject to revised standards. Since the list of those areas
that will not likely be subject to the ordinance is much shorter, we have listed them
below. Areas not on the list below will likely have landscape areas greater than 500
square feet due to a combination of larger lot sizes, larger setback requirements and lot
coverage limitations.
Areas where new regulations will not likely apply:
• West Newport
• Newport Shores
• Balboa Island
• Lido Island
• Balboa Peninsula (with the exception of Peninsula Point)
• Old Corona del Mar (except lots with 20 -foot setbacks)

Of course, whether the 500 -square -foot threshold will be exceeded is subject to design
preference, but staff does believe that most new homes in areas not listed above will be
required to submit a complete Landscape Documentation package or use the PCO.
Conclusion
The OC Model provided the framework for the proposed amendments to the City's
Water Efficient Landscape Ordinance and Design Standards (Attachments A and B).
While the State's Model Ordinance is a complex and lengthy document, the OC Model
provides a framework which meets the "at least as effective as" requirement of the
State's new Model Ordinance. It provides as much simplicity, efficiency, and flexibility as
possible. It retains the self -certification process and provides for the less burdensome
PCO. Continued use of the OC Model provisions provides consistency across Orange
County for landscape professionals. Therefore, staff recommends adoption of the
proposed new Water Efficient Landscaping Ordinance (Chapter 14.17 of the Municipal
Code).
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this Ordinance is exempt from the California
Environmental Quality Act (CEQA) pursuant to Section 15307, Class 7 (Actions by
Regulatory Agencies for the Protection of Natural Resources) of the CEQA Guidelines,
California Code of Regulations, Title 14, Chapter 3. This class provides an exemption
for actions taken by regulatory agencies as authorized by state law or local ordinance
which assure the maintenance, restoration, or enhancement 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 environmental impacts. It
is therefore exempt from the provisions of CEQA.

B. "Applied water" means the portion of water supplied by the irrigation system to
the landscape.
C. "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 irrigated area and the evapotranspiration
requirements of landscaping.
D. "Design standards" refers to the Design Standards for Implementation of the
Water Efficient Landscape Ordinance, which are hereby adopted by reference and may
be amended from time -to -time, which describe procedures, calculations, and
requirements for landscape projects subject to this chapter.
E. "Ecological restoration project" means a project where the site is intentionally
altered to establish a defined, indigenous, historic ecosystem.
F. "Estimated applied water use" or "EAWU" means the average annual total
amount of water estimated to be necessary to keep plants in a healthy state. EAWU is
based on the reference evapotranspiration rate, the size of the landscaped area, plant
water use factors, and the irrigation efficiency within each hydrozone.
G. "ET adjustment factor" or "ETAF" of 0.55 (fifty-five (55) percent) for residential
areas and 0.45 (forty-five (45) percent) for non-residential areas, 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.
The ETAF for new and existing (non -rehabilitated) Special Landscape Area shall not
exceed 1.0 (one hundred (100) percent). The ETAF for existing non -rehabilitated
landscapes is 0.8 (eighty (80) percent).
H. "Hardscapes" means any durable material or feature (pervious and non -pervious)
installed in or around a landscaped area, such as pavements or walls. Surface area of
pools and other water features is considered part of the landscaped area and not
considered hardscapes for purposes of this chapter.
I. "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 chapter is 0.75
(seventy-five (75) percent) for overhead spray devices and 0.81 (eighty-one (81)
percent) for drip systems with an overall irrigation efficiency of 0.71 (seventy-one (71)
percent).. Greater irrigation efficiency can be expected from well designed and
maintained systems.
J. "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

and Section 6721 of the California Food and Agriculture Code, or any successor
statutes.
O. "Local water supplier" means any entity, including, but not limited to, a public
agency, city, county, or private water company that provides retail water service.
P. "Maximum applied water allowance" or "MAWK is the upper limit of annual
applied water for the established landscaped area as specified in Section 2.2 of the
design standards. 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. MAWA = (ETo) (0.62)
[(ETAF x LA) + ((1-ETAF) x SLA)]
Q. "Ministerial permit" means an authorizing document issued by the City's
Community Development Department in conjunction with a landscape project which
may include, but is not limited to: grading, pools, spas, fountains, ponds, retaining walls,
fences and walls, shade structures, trellis structures, barbecues, outdoor fireplaces, etc.

Ordinance No.
Page 6 of 10
T. "Pervious" means any surface or material that allows the passage of water
through the material and into the underlying soil.
U. "Plant factor" or "plant water use factor" is a factor, when multiplied by ETo,
which estimates the amount of water needed by plants. For purposes of this chapter,
the plant factor range for very low water use plants is zero (0) to 0.1 (ten (10) percent);
the plant factor for low water use plants is 0.1 (ten (10) percent) to 0.3 (thirty (30)
percent); the plant factor range for moderate water use plants is 0.4 (forty (40) percent)
to 0.6 (sixty (60) percent); and the plant factor range for high water use plants is 0.7
(seventy (70) percent) to 1.0 (one hundred (100) percent). Plant factors cited in this
chapter are derived from the Department of Water Resources publication "Water Use
Classification of Landscape Species." Plant factors may also be obtained from
horticultural researchers from academic institutions or professional associations as
approved by the California Department of Water Resources (DWR).
V. "Recycled water" or "reclaimed water" means a wastewater which, as a result of
treatment, is suitable for non -potable uses not intended for human consumption such as
landscape irrigation and water features.
W. "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 D of the design standards
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 allowance.
X. "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 with non-
volatile memory shall be required for irrigation scheduling in all irrigation systems,
recommending U.S. EPA WaterSense labeled devices as applicable.
Y. "Special landscaped area" or "SLA" 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, or areas dedicated to active play
such as community pools and spas, parks, sports fields, golf courses, or areas where
turf provides a playing surface. These areas may have an ET adjustment factor (ETAF)
up to 1.0 (one hundred (100) percent).
Z. "Turn' means a ground cover surface of mowed grass. Annual bluegrass,
Kentucky bluegrass, perennial ryegrass, red fescue, and tall fescue are cool -season
grasses. Bermuda grass, Kikuyu grass, seashore paspalum, St. Augustine grass,
zoysia grass, and Buffalo grass are warm -season grasses.
AA. "Valve" means a device used to control the flow of water in an irrigation system.
3-13
Ordinance No.
Page 7 of 10
BB. "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.
14.17.020 Applicability.

2.2 Water Efficient Landscape Calculations and Alternatives
The project applicant shall provide the calculated Maximum Applied Water Allowance
(MAWA) and Estimated Applied Water Use (EAWU) for the landscaped area as part of
the Landscape Documentation Packaqe submittal to the City. The MAWA and EAWU
shall be calculated based on completing the Water Efficient Landscape Worksheets
(Appendix C) which contain information on the plant factor, irrigation method, irrigation
efficiency and area associated with each hydrozone. Calculations are then made to
show that the evapotranspiration adjustment factor (ETAF) for the landscape project
does not exceed a factor of 0.55 for residential areas and 0.45 for non-residential areas,
exclusive of Special Landscape Areas. The ETAF for a landscape project is based on
the plant factors and irrigation methods selected. The Maximum Applied Water
Allowance is calculated based on the maximum ETAF allowed (0.55 for residential
areas and 0.45 for non-residential areas) and expressed as annual gallons required.
The EAWU is calculated based on the plants used and irrigation method selected for
the landscape design.
0
3-24
A. The EAWU allowable for the landscaped area shall not exceed the MAWA.
The MAWA shall be calculated using an evapotranspiration adjustment
factor (ETAF) of 0.55 residential areas and 0.45 for non-residential areas
except for the portion of the MAWA applicable to any Special Landscaped
Areas within the landscape project, which shall be calculated using an
ETAF of 1.0. Where the design of the landscaped area can otherwise be
shown to be equivalently water -efficient, the project applicant may submit
alternative or abbreviated information supporting the demonstration that the
annual EAWU is less than the MAWA, at the discretion of and for the
review and approval of the City.
B. Water budget calculations shall adhere to the following requirements:
1. The MAWA shall be calculated using the Water Efficient Landscape
Worksheets and equation presented in Appendix C.
2. The EAWU shall be calculated using the Water Efficient Landscape
Worksheets and equation presented in Appendix C.
3. For the calculation of the MAWA and EAWU, a project applicant
shall use the ETo values from the closest location listed the
Reference Evapotranspiration Table in Appendix D. For
geographic areas not covered in Appendix D, data from other
cities or zip codes located nearby in the same reference
evapotranspiration zone may be used.
4. For calculation of the EAWU, the plant water use factor shall be
determined as appropriate to the project location from the Water
Use Efficiency of Landscape Species (WUCOLS) Species
Evaluation List from horticultural researchers with academic
institutions or professional associations as approved by the
California Department of Water Resources (DWR). The plant factor
ranges from 0 to 0.1 for very low water use plants, 0.1 to 0.3 for low
water use plants, 0.4 to 0.6 for moderate water use plants, and 0.7
to 1.0 for high water use plants.
5. For calculating the EAWU, the plant water use factor shall be
determined for each valve hydrozone based on the highest -water -
use plant species within the zone. The plant factor for each
hydrozone may be required to be further refined as a "landscape
coefficient," according to protocols defined in detail in the WUCOLS
document, to reflect planting density and microclimate effects on
water need at the option of the project applicant or the City.
6. For calculation of the EAWU, the area of a water feature shall be
defined as a high water use hydrozone with a plant factor of 1.0.
5
3-25
7. For calculation of the EAWU, a temporarily irrigated hydrozone
area, such as an area of highly drought -tolerant native plants that
are not intended to be irrigated after they are fully established, shall
be defined as a very low water use hydrozone with a plant factor of
0.1.
8. For calculation of the MAWA, the ETAF for Special Landscape
Areas (SLA) shall be set at 1.0. For calculation of the EAWU, the
ETAF for SLA shall be calculated as the SLA plant factor divided by
the SLA irrigation efficiency factor.
9. Irrigation efficiency (IE) of the irrigation heads used within each
hydrozone shall be assumed to be as follows, unless otherwise
indicated by the irrigation equipment manufacturer's specifications
or demonstrated by the project applicant:

C. The Maximum Applied Water Allowance shall adhere to the
following requirements:
(1) The Maximum Applied Water Allowance shall be calculated
using the equation presented in Appendix C. The reference
evapotranspiration (ETo) values used in this calculation are
from the Reference Evapotranspiration Table in Appendix D
and are for planning purposes only. For actual irrigation
scheduling, automatic irrigation controllers are required and
shall use current ETo data, such as from the California
Irrigation Management Information System (CIMIS), other
equivalent data, or soil moisture sensor data.

exception of hydrozones with plants of mixed water use, as specified in
Section 2.5(A)(2)(d) of these Design Standards.
3-28
C. Plants shall be selected and planted appropriately based upon their
adaptability to the climatic, geologic, and topographical conditions of the
project site. Methods to achieve water efficiency shall include one or more
of the following
1. use the Sunset Western Climate Zone System, or equivalent
generally accepted models which takes into account temperature,
humidity, elevation, terrain, latitude, and varying degrees of
continental and marine influence on local climate;
2. recognize the horticultural attributes of plants (i.e., mature plant
size, invasive surface roots) to minimize damage to property or
infrastructure (e.g., buildings, sidewalks, and power lines) to allow
for adequate soil volume for healthy root growth; and
3. consider the solar orientation for plant placement to maximize
summer shade and winter solar gain.
D. Turf is discouraged on slopes greater than 25% where the toe of the slope
is adjacent to an impermeable hardscape and where 25% means 1 foot of
vertical elevation change for every 4 feet of horizontal length (rise divided
by run x 100 = slope percent).
E. High water plants, characterized by a plant factor of 0.7 to 1.0 are
prohibited in street medians.

Fuel Modification Zones shall comply with requirements of the Newport
Beach Fire Department, where applicable. Design, installation and
maintenance of Hazard Reduction and Fuel Modification Zones shall be
subject to review and approval by the Newport Beach Fire Department
prior to installation. When conflicts between water conservation and fire
safety design elements exist, the fire safety requirements shall have
priority. (Reference: Newport Beach fire Prevention Guidelines, G.01 and
G.02)
G. The use of invasive plant species and/or noxious plant species , such as
those listed by the California Invasive Plant Council is strongly
discouraged.
H. The architectural guidelines of a common interest development, which
include community apartment projects, condominiums, planned
developments, and stock cooperatives, shall not prohibit or include
conditions that have the effect of prohibiting the use of water efficient plant
species as a group.

period. For the efficient use of water, an irrigation system shall meet all the
requirements listed in this section and the manufacturer's
recommendations. The irrigation system and its related components shall
be planned and designed to allow for proper installation, management, and
maintenance. An irrigation design plan meeting the following design criteria
shall be submitted as part of the Landscape Documentation Packaqe.
1. System
(a) Landscape water meters, defined as either a dedicated
water service meter or private sub meter, shall be installed
for all non-residential irrigated landscapes of 1,000 sq. ft. but
not more than 5,000 sq. ft. (the level at which Water Code
535 applies) and residential irrigated landscapes of 5,000 sq.
ft. or greater. A landscape water meter may be either:
1. A customer service meter dedicated to landscape use
provided by the local water purveyor; or
2. A privately owned meter or sub meter.
(b) Automatic irrigation controllers utilizing either
evapotranspiration or soil moisture sensor data with non-
volatile memory shall be required for irrigation scheduling in
all irrigation systems recommending U.S. EPA WaterSense
labeled devices as applicable.
(c) If the water pressure is below or exceeds the recommended
pressure of the specified irrigation devices, the installation of
a pressure regulating device is required to ensure that the
dynamic pressure at each emission device is within the
manufacturer's recommended pressure range for optimal
performance.
1. If the static pressure is above or below the required
dynamic pressure of the irrigation system, pressure -
regulating devices such as inline pressure regulators,
booster pumps, or other devices shall be installed to
meet the required dynamic pressure of the irrigation
system.
2. Static water pressure, dynamic or operating pressure,
and flow reading of the water supply shall be measured
at the point of connection. These pressure and flow
12
3-32
measurements shall be conducted at the design stage. If
the measurements are not available at the design stage,
the measurements shall be conducted at installation.
(d) Sensors (rain, freeze, wind, etc.), either integral or auxiliary,
that suspend or alter irrigation operation during unfavorable
weather conditions shall be required on all irrigation
systems, as appropriate for local climatic conditions.
Irrigation should be avoided during windy or freezing
weather or during rain.
(e) Backflow prevention devices shall be required to protect the
water supply from contamination by the irrigation system. A
project applicant shall refer to the applicable City code (i.e.,
public health) for additional backflow prevention
requirements.
(f) A master shutoff valve shall be as close as possible to the
point of connection and is required on all projects, with the
exception for landscapes that make use of technologies that
allow for the individual control of sprinklers that are
individually pressurized in a system equipped with low
pressure shut down features.
(g) High flow sensors that detect and report high flow conditions
created by system damage or malfunction are recommended
required for all non-residential landscapes and residential
landscapes of 5,000 square feet or larger. The flow sensor
must be in combination with a master shut-off valve.
(h) Manual Isolation valves (such as a gate valve, ball valve, or
butterfly valve) shall be required downstream of the point of
connection of the water supply to minimize water loss in
case of an emergency (such as a main line break) or routine
repair.
(i) The irrigation system shall be designed to prevent runoff, low
head drainage, overspray, or other similar conditions where
irrigation water flows onto non -targeted areas, such as
adjacent property, non -irrigated areas, hardscapes,
roadways, or structures.
(j) Relevant information from the soil management plan, such
as soil type and infiltration rate, shall be utilized when
designing irrigation systems.
(k) The design of the irrigation system shall conform to the
hydrozones of the Landscape Design Plan.
13
3-33
(I) All irrigation emission devices must meet the requirements
set in the American National Standards Institute (ANSI)
standard, American Society of Agricultural and Biological
Engineers'/International Code Council's (ASABE/ICC) 802-
2014 "Landscape Irrigation Sprinkler and Emitter Standard,
All Sprinkler heads installed in the landscape must document
a distribution uniformity low quarter of 0.65 or higher using
the protocol defined in ASBE/ICC 802-2014.
(m) Average irrigation efficiency for the project shall be
determined in accordance with the EAWU calculation sheet
in Appendix C. Unless otherwise indicated by the irrigation
equipment manufacturer's specifications or demonstrated by
the project applicant, the irrigation efficiency of the irrigation
heads used within each hydrozone shall be as listed in
Section 2.2.C(9).
(n) It is highly recommended that the project applicant inquire
with the City or the applicant's water supplier about peak
water operating demands (on the water supply system) or
water restrictions that may impact the effectiveness of the
irrigation system.
(o) In mulched planting areas, the use of low volume irrigation is
(drip or low volume overhead irrigation) required to maximize
water infiltration into the root zone; with the exception of
areas with fuel modification requirements and/or those that
require plant establishment to comply with the Newport
Beach Municipal Code Chapter 15.10 (Excavation and
Grading.
(p) Sprinkler heads and other emission devices shall have
matched precipitation rates, unless otherwise directed by the
manufacturer's recommendations.
(q) Head to head coverage is recommended. However, sprinkler
spacing shall be designed to achieve the highest possible
distribution uniformity using the manufacturer's
recommendations.
(r) Swing joint components are required on all sprinklers subject
to damage that are adjacent to hardscapes or in high traffic
areas.
(s) Check valves or anti -drain valves are required on all
sprinkler heads where low point drainage could occur.
14

(t) Areas less than ten (10) feet in width in any direction shall be
irrigated with subsurface irrigation or other means that
produces no runoff or overspray.
(u) Overhead irrigation shall not be permitted within 24 inches of
any non -permeable surface. Allowable irrigation within the
setback from non -permeable surfaces may include drip, drip
line, or other low flow non -spray technology. The setback
area may be planted or unplanted. The surfacing of the
setback may be mulch, gravel, or other porous material.
These restrictions may be modified if:

The purpose of this chapter and related design standards document is to establish an
alternative model acceptable under AB 1881 (2006) as being at least as effective as the state
model water -efficient landscape ordinance, in order to:
A. Promote the benefits of consistent landscape ordinances with neighboring local and
regional agencies;
B. Promote the values and benefits of landscapes while recognizing the need to invest water
and other resources as efficiently as possible;
C. Establish a structure for planning, designing, installing, and maintaining and managing
water -efficient landscapes in new construction and rehabilitated projects;
D. Establish provisions for water management practices and water waste prevention for
existing landscapes;
E. 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;

1. Purpose and Applicability
1.1 Purpose
A. The primary purpose of these Water Efficient Landscape Design Standards
(Design Standards) is to provide procedural and design guidance for
project applicants proposing new landscape installation or rehabilitation
projects that are subject to the requirements of the Water Efficient
Landscape Ordinance (Chapter 14.17 of the Newport Beach Municipal
Code). This document is also intended for use and reference by City staff
in reviewing and approving designs and verifying compliance with the
Water Efficient Landscape Ordinance. The general purpose of the Water
Efficient Landscape Ordinance is to promote the design, installation, and

2.2 Water Efficient Landscape Calculations and Alternatives
A. The project applicant shall provide the calculated Maximum Applied Water
Allowance (MAWA) and Estimated Applied Water Use (EAWU) for the
landscaped area as part of the Landscape Documentation Package
submittal to the City. The MAWA and EAWU shall be calculated based on
completing the Water Efficient Landscape Worksheets (Appendix C)7
which contain information on the plant factor, irrigation method, irrigation
efficiency and area associated with each hydrozone. Calculations are
then made to show that the evaaotransairation adiustment factor (ETAF)
for the landscape project does not exceed a factor of 0.55 for residential
areas and 0.45 for non-residential areas, exclusive of Special Landscape
Areas. The ETAF for a landscape project is based on the plant factors and
irrigation methods selected. The Maximum Applied Water Allowance is
calculated based on the maximum ETAF allowed (0.55 for residential
areas and 0.45 for non-residential areas) and expressed as annual gallons
required. The EAWU is calculated based on the plants used and irrigation
method selected for the landscape design.
B. The EAWU allowable for the landscaped area shall not exceed the MAWA.
The MAWA shall be calculated using an evapotranspiration adjustment
factor (ETAF) of 0.7 of 0.55 residential areas and 0.45 for non-residential
areas except for the portion of the MAWA applicable to any sSpecial
fLandscaped aAreas within the landscape project, which shall be
calculated using an ETAF of 1.0. -Where the design of the landscaped
area can otherwise be shown to be equivalently water -efficient, the project
applicant may submit alternative or abbreviated information supporting the
demonstration that the annual EAWU is less than the MAWA, at the
discretion of and for the review and approval of the City.
C. Water budget calculations shall adhere to the following requirements:
1. The MAWA shall be calculated using the Water Efficient Landscape
Worksheets and equation presented in Appendix C. The ex mp e

low water use plants, 0.4 to 0.6 for moderate water use plants, and
0.7 to 1.0 for high water use plants.
5. For calculating the EAWU, the plant water use factor shall be
determined for each valve hydrozone based on the highest -water -
use plant species within the zone. The plant factor for each
hydrozone may be required to be further refined as a "landscape
coefficient," according to protocols defined in detail in the WUCOLS
document, to reflect planting density and microclimate effects on
water need at the option of the project applicant or the City.
6. For calculation of the EAWU, the area of a water feature shall be
defined as a high water use hydrozone with a plant factor of 1.0.
7. For calculation of the EAWU, a temporarily irrigated hydrozone
area, such as an area of highly drought -tolerant native plants that
are not intended to be irrigated after they are fully established, shall
be defined as a very low water use hydrozone with a plant factor of
0.1.
8. For calculation of the MAWA, the ETAF for SpeGiol lonr-lSGaped
areas Special Landscape Areas (SLA) shall be set at 1.0. For

Chapter 2.7. Model Water Efficient
Landscape Ordinance
§ 490. Purpose.
(a) The State Legislature has faun&
(1) that the waters of the state are of limited. supply and are subject to
ever increasing demands;
(2) that the continuation of California's economic prosperity is depen-
dent on the availability of adequate supplies of water for ftrtttre uses;
(3) that it is the policy of the State to promote theconservation and effi-
cient use of water and to prevent the waste of this valuable resource;
(4) that. landscapes are essential to the quality of life in California by
providing areas for active and passive recreation and as an enhancement.
to the envirormient by cleaning air and water, :preventing erosion, offer-
ing fire protection, and replacing ecosystems lost to development;
(5) that landscape design, installation, maintenance and management
can grad should be water efficient;
(6) that Section 2 of Article X of the California Constitution specifies
thatthe right to use water is limited to the amount reasonablyrequiredfor
the beneficial use to be served and the right does not and shall not extend
to waste or unreasonable method of use.
(b) Consistent with the le.gis.lative findings, the purpose of this model
ordinance is to:
(1) promote the values and benefits of landscaping practices that inte-
grate and go beyond the conservation and efficient use of water;
(2) establish a structure for planning, designing, installing, maintain-
ing and managing water efficient landscapes in new constn€etion and re-
habilitated projects by encout aging the use of a watershed approach that
requires cross -sector collaboration of industry, government and proper-
ty owners to achieve the many benefits possible,
(3) establish provisions for water management practices and water
waste prevention for existing landscapes,
(4) use water efficiently -without waste by setting a Maximum Applied
Nater Allowance its an upper limit for water use and reduce water use to
the lowest practical amotutt;
(5) prou-tote the benefits of consistent landscape ordinances with
neighboring local and regional agencies;
(6) encourage local agencies and water purveyors to use economic in-
centives that promote the efficient use of water, such as implementing a
tiered tate, structure: and
(7) encourage local agencies to designate the necessary authority that
implements and enforces the provisions of the Model Water Efficient
Landscape Ordinance or its local landscape ordinance,
(c) Landscapes that are planned, designed, installed, managed and
maintained with the watershed based approach can improve California's
environmental conditions and provide benefits and realize sustainability
goals. Such landscapes will snake the urban environment resilient in the
face of climatic extremes. Consistent with the legislative findings and
purpose of the Ordnance, conditions in the urban setting will be im-
proved by:
(1) Creating the conditions to support life iathe soil by reducing com-
paction, vtcazporatiltg organic matter that increases w ter retention, and
promoting productive plant growth that lea dsto more carbon storage, ox-
ygen production, shade, habitat and esthetic benefits.
(2) Minimizing energy use by reducing irrigation water requirements,
reducing relianee on petrolctum based fertilizers and pesticides, and
planting climate appropriate shade tees its urban areas.
(3) Conserving water by capturing and reusing raittvvater and graywa-
ter wherever possible and selecting climate appropriate plants that need
minimal supplemental water after establishtncm#
(4) Protecting air and water duality by reducing power equipment use
and landfill disposal trips, selecting recycled and locally sourced inateri-

als, and using compost, mulch and efficient irrigation equipment to pre-
vent erosion.
(5) Protecting existing habitat and creating new habitat by choosing
local native plants, climate adapted non natives and avoiding invasive
plants. Utilizing integrated pest management with least toxic methods as
the first course of action.

§ 492.7. Irrigation Design Plan.
(a) This section applies to landscaped areas requiring permanent ir-
rigation, not areas that require temporary irrigation solely for the plant
establishment period. For the efficient use of water, an irrigation systcnt
shall meet all the requirements listed in this section and the rimaufactur-
ers' recorumendations. The irrigation system and its related components
shall be planned and designed to allow for proper installation, manage-
ruent, and maintenance. An irrigation design plan tweeting the following
design criteria shall be submitted as part of the Landscape Docruuenta-
tion Package.
(1) System
(A) Landscape water meters, defined as either a dedicated wager ser-
vice meter or private submeter, shall be installed for all non-residential
irrigated landscapes of 1,000 sq. ft, but not more than 5,000 sq.ft. (the lev-
el at which Water Code 535 applies) and residential irrigated landscapes
of 5,000 sq. ft. or greater. A landscape water meter may be either:
1, a customer service meter dedicated to landscape use provided by the
local water purveyor; or
2. a privately owned meter or submeter.
(B) Automatic irrigation controllers utilizing either evapotranspira-
tion or soil moisture sensor data utilizing non-volatile nrernmy shall be
required for irrigation scheduling in all irrigation systems.
(C) If the water pressure is below or exceeds the recommended pres-
sure of the specified irrigation devices, the installation of a.pressure regu-
Wing device is required to ensure that the dynamic pressure at each emis-
sion device .is within the manufacturer's recommended pressure range
for optimal performance.
1. If the static pressure is above or below the required dynamic pres-
sure of the irrigation system, pressurc-regulating devices such as inline
pressure regulators, booster pinups, or other devices shall he installed to
meet the required dynamic pressure of the irrigation system.
2. Static water pressure, dynamic or operating pressure, and flow read-
ing of the water supply shall be measured at the point of connection.
These pressure and flow measurements shall be conducted at the design
stage. If the measurements are not available at the design stage, the mea-
surenrents shall be conducted at installation.
(I)) Sensors (rain, freeze, wind, etc.), either integral or auxiliary, that
suspend or alter irrigation operation during unfavorable weather condi-
tions shall be required on all irrigation systems, as appropriate for local
climatic conditions. Irrigation should be avoided during windy or freez-
ing weather or during rain.
(E) Manual shut-off valves (such as a gate valve, ball valve, or butter-
fly valve) shall be required, as close as possible to the point of connection
of the water supply, to minimize, water loss in case of an emergency (Stich
as a main line break) or routine repair.
(F) Backflow prevention devices shall be required to protect the water
supply from contamination by the irrigation system. A project applicant
shall refer to the applicable local agency code (i.e., public health) for
additional backflow prevention requirements.
(G) Flow sensors that detect high flow conditions created by system
damage or malfitnction are required for all ontion-residential landscapes
and residential landscapes of 5000 sq. ft. or larger.
(I) Master shut-off valves are required on all projects except land-
scapes that make use of technologies that allow for the individual control
of sprinklers that are individually pressurized in a system equipped with
loth pressure shut down features.
(T) The 'irrigation system shall be designed to prevent runoff low head
drainage, overspray, or other similar conditions where irrigation water
flows onto non targeted areas, such as adjacent property, nor irrigated
areas, hardscapes, roadways, or structures,
( Relevant information from the soil mane gement plan, .such as soil
type and infiltration rate, shall be utilized tvlten designing irrigation sys-
tems.
(If) The design of the irrigation system shall conform to die hydro -
zones of the landscape design pian.
(I.) The irrigation system must be designed and installed to meet, at a
minitumn, the irrigation efficiency criteria as described in S ection 492.4
regarding the Maximum Applied Water Allowance.
(M) All irfrgation emission devices must meet the requirements set in
the Arnerican National Standards Institute (ANSI) standard, American
Society of Agricultural and Biological Engincers'Anternational Code
Council's (ASABE/ICC) 8132-2014 "Landscape Irrigation Sprinkler and
Emitter Standard, All sprinkler heads installed in the landscapemtut doc-
ument a distributionn uniformity low quarter of 0,65 or higher using the
protocol defined in ASABEACC 302•-2014.
(I) It is higlily recommendcd that the proj ect. applicant or local agency
inquire with thelocal water purveyor about peak water operating de-
mands (on the water supply system) or water restrictions that may impact
the effectiveness of the irrigation system.
(0) In mulched planting areas, the rise of low volume irrigation is re-
quired to maximize water infiltration into the root zone.
(P) Sprinkler heads and other ennission devices .shall have matched
precipitation rates, unless otherwise directed by the nnanufacturer's rec-
ounnendations.
(Q) Head to head coverage is recommended. Hn-wever, sprinkler spac-
ing shall be designed to achieve the highest possible distribution unifor-
mity using the manufacturer's recommendations,
(R) Swing joints or other riser -protection components are required on
all risers subject to damage that are adjacent to hardscapes or: in high traf-
fic areas of ttufgrass,

§ 492.8 BARCLAYS CALIFORNIA CODE OF REGULATIONS Title 23
(S) Check valves or anti -drain valves are required on all sprinkler
heads where loin point drainage could occur.
(T) Areas less than ten (10) feet in width in any direction shall be irri-
gated with subsurface irrigation or other means that produces no runoff
or overspray.
(U) Overhead irrigation shall not be penuitted within 24 inches of any
non permeable surface. Allowable irrigation within the setback from
non—permeable surfaces may include drip, drip line, or other low- flow
non—spray technology. The setback area may be planted or unplanted.
The surfacing of the setback may be mulch, gravel, or other porous mate-
rial. These restrictions may be modified i£:
1. the landscape area is adjacent to permeable surfacing and no runoff
occurs, or
2. the adjacent non—peen eable surfaces are designed and constricted
to drain entirely to landscaping. or
3. the irrigation designer specifies an alternative dosign or technology,
as part of the Landscape Documentation Package and clearly demon-
strates strict adherence to irrigation .system design criteria in Section
492,7 (a)(1)(I). Prevention of overspray and runoff must be confirmed
during the irrigation audit.
(V) Slopes greater than 25% shall not be irrigated with arm irrigation
system with a application rate exceeding 0.75 inches per hour. This re-
striction may be modified if the landscape designer specifies arra alterna-
tive design or technology, as part of the Landscape Doctunentation Pack-
age, and clearly demonstrates no runoff or er osionwill occur. Prevention
of runoff and erosion must be confirmed during the irrigation audit.
(2) Hydrozone
(A) Each valve shall irrigate a bydr•ozone with similar site, slope, stun
exposure, soil conditions, and plant.materia.ls, Nvitlm sin&ar water use.
(B) Sprinkler heads and other emission devices shall be selected based
on what is appropriate for the plant type within that hydrozone.
(C) Where feasible, trees shall be placed on separate valves from
shrubs, groundcovem, and turf to facilitate the appropriate irrigation of
trees. The mature size and extent of the root zone shall be considered
when designing irrigation for the tree.
(D) Individual hydrozones that immix plants of moderate and low water
use, or moderate and high water use, may be allowed if:
1, plant factor calculation is based on the proportions of the respective
plant water uses and their plant factor: or
2, theplant factor of the higher water using plant is used for calcula-
tions.
(E) Individual hydrazones that faux high and low water use plants shall
not be pernmitted.
(F) On the landscape design plan and h igation design plain, hydrozone
areas shall be designated by mrmber, letter, or other designation. On the
ir i gation design plan, designate the areas irrigated by each valve, and as-
sign a ntunber to each valve. Use this valve number in the Hydrozonc In-
formation Table (see Appendix B Section A), This table can also assist
with the irrigation audit and pr'ogr•arnnming the controller.
(b) The irrigation design plan, at a minimum, shall contain:
(1) location and size of separate water meters for landscape;

Quality Control Board for information on any applicable stormwater
technical requirements,
(c) All planted landscape areas are required to have friable soil to max-
imize neater retention and infiltration. Refer to § 492.6(a)(3).
(d) It is strongly recotntnended that landscape areas be designed for
capture and infiltration capacity that is sufficient to prevent runoff from
innpervious surfaces (i.e. roof and paved areas) from either: the one inch,.
24-hour rain event or (2) the 85th percentiles 24-hour rain event, and/or
additional capacity as required by any applicable: local, regional, state or
federal regulation.
(e) It is recornunended that storm watcrprojcets incorporate any of the
following elernnents to improve on-sitc storm water anti dry weather tun-
• Minimize the area of impervious surfaces such as paved areas, roof
and Concrete driveways.
• Incorporate pervious or porous surfaces (e,g,, gravel, permeable
pavers or blocks, per rious or porous concrete) that miniruize run-
off.
• Direct runoff frompavedsui-facesandroofareas into plantingbeds
or landscaped areas to maximize site Water capture and reuse.
• Incorporate rain gardens, cisterns, and other rain harvesting or
catcl>tuent systems.
• Incorporate infiltration beds, swales, basins and drywAls to cap-
ture storm water and dry weather runoff and increase percolation
into the soil.
• Consider constructed wetlands and ponds that retain water, equal-
ize excess flow, anal filter pollutants.

AMENDING [Chapter/Title/Division
1 OF THE CODE BY ADDING
SECTIONS REGARDING
THE ADOPTION OF A WATER EFFICIENT LANDSCAPE
ORDINANCE
BE IT ORDAINED, by the City Council of the City of , as follows:
Section 1. That [Chapter _, Article _ Division _, of the
Code is hereby amended by adding sections J to read as follows:
1. Purpose
(a) 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.
(b) The City hereby finds that:
(1) Orange County has an established, large reclaimed water
infrastructure system;
1
3-140
(2) Allocation -based and tiered water rate structures allow public
agencies to document water use in landscapes;
(3) Incentive -based water use efficiency programs have been actively
implemented within Orange County since before 1991;
(4) Current local design practices in new landscapes strive to achieve
the intent of the State Model Water Efficient Landscape Ordinance
water use goals;
(5) all water services within the City are metered and billed based on
volume of use;
(6) Orange County is a leader in researching and promoting the use of
smart irrigation controllers with more than 12,900 installations as
of June 2009 and promotion of sustainable landscape
transformation with more than 30 million square feet of turf
removal;
(7) All new irrigation controllers sold after 2012 within Orange
County will be smart irrigation controllers;
(8) Landscape plan submittal and review has been a long standing
practice in ; and
(9) The average rainfall in Orange County is approximately 12 inches
per year.

3-141
(c) Consistent with these findings, the purpose of the City's Water Efficient
Landscape Ordinance is to establish an alternative model acceptable under
Governor Brown's April 1, 2015 Drought Executive Order (B-19-25) 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 a budget -based tiered -
rate structure, providing rebate incentives and offering
educational programs.

4. Delegation.
The City may delegate to, or enter into a contract with, a local agency to
implement, administer, and/or enforce any of the provisions of the Water Efficient
Landscape Ordinance on behalf of the City.
5. Definitions.
The following definitions are applicable to this [chapter/division/title]:
"Aggregate landscape areas " pertains to the areas undergoing development as one
project or for production home neighborhoods or other situations where multiple parcels
are undergoing development as one project, but will eventually be individually owned.
"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 irrigated area and the evapotranspiration requirements of
landscaping.
"Community Aesthetics Evaluation" — While not subject to a permit, plan check or
design review, the Community Aesthetics Evaluation may be performed to ensure the
aesthetic standards of the community and irrigation efficiency intent is maintained.
"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.
"Evapotranspiration adjustment factor" or "ETAF" of 0.55 for residential areas and 0.45
for non-residential areas, 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. The ETAF for new and existing (non -
0
3-145
rehabilitated) Special Landscape Area shall not exceed 1.0. The ETAF for existing non-
rehabilitated landscapes is 0.8.
"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.
"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 irrigation efficiency for purposes of this Water Efficient Landscape
Ordinance are 0.75 for overhead spray devices and 0..81 for drip 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,

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. MAWA = (ETo) (0.62) [(ETAF x LA)
+ ((1-ETAF) x SLA)]
"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.
"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 local agencies 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 very low water use plants is 0 to 0.1; 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
publication "Water Use Classification of Landscape Species." Plant factors may also be
obtained from horticultural researchers from academic institutions or professional
associations as approved by the California Department of Water Resources (DWR).
"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 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.
"Rehabilitated landscape" means any re -landscaping project that meets the applicability
criteria of Section 1.1(a), where the modified landscape area is greater than 2,500 square
feet.
3-147

evapotranspiration or soil moisture sensor data with non-volatile memory shall be
required for irrigation scheduling in all irrigation systems, recommending U.S. EPA
WaterSense labeled devices as applicable.
"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 recreational 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.

2. Submittal Requirements for New Landscape Installations or Landscape Rehabilitation
Projects
(A) Discretionary approval is typically required for landscape projects that are subject
to site plan reviews, or where a variance from a local building code is requested,
or other procedural processes apply such that standard or special conditions of
approval may be required by the City. Discretionary projects with conditions of
approval may be approved administratively by City staff, or acted on formally by
the Planning Commission, City Council, or other jurisdictional authority. A
typical standard condition of approval reads:
"Landscaping for the project shall be designed to comply with the City's
Water Efficient Landscape Ordinance and with the Guidelines for
Implementation of the Water Efficient Landscape Ordinance. "
Landscape or water features that typically require a ministerial permit (i.e., a
building, plumbing, electrical, or other similar permit), thereby triggering
compliance with the Water Efficient Landscape Ordinance requirements
independently of the need for discretionary approval include, but are not limited
to, swimming pools, fountains or ponds, retaining walls, and overhead trellises.
2.2 Elements of the Landscape Documentation Package
(A) A Landscape Documentation Package is required to be submitted by the project
applicant for review and approval prior to the issuance of ministerial permits for
landscape or water features by the City, and prior to start of construction. Unless
otherwise directed by the City, the Landscape Documentation Package shall
include the following elements either on plan sheets or supplemental pages as
directed by the City:
(1) Project Information, including, but not limited to, the following:
(a) Date;
(b) Project name;
(c) Project address, parcel, and/or lot number(s);
(d) Total landscape area (square feet) and rehabilitated landscape
area (if applicable);
(e) Project type (e.g., new, rehabilitated, public, private, cemetery,
homeowner -installed);
(f) Water supply type (e.g., potable, recycled, or well) and
identification of the local retail water purveyor if the project
applicant is not served by a private well;
K,
3-154
(g) Checklist or index of all documents in the Landscape

stamp, as applicable, signature, contact information (including
email and telephone number), license number, and date, certifying
the statement that "The design of this project complies with the
requirements of the City's Water Efficient Landscape Ordinance"
and shall bear the signature of the landscape professional as
required by law; and
(j) Any other information the City deems relevant for determining
whether the landscape project complies with the Water Efficient
Landscape Ordinance and these Guidelines.
(2) Maximum Applied Water Allowance (MAWA) and Estimated Applied
Water Use (EAWU) expressed as annual totals including, but not limited
to, the following:
(a) Water Efficient Landscape Worksheet (optional at discretion of the
City) for the landscape project;
(b) Hydrozone information table (optional at the discretion of the City)
for the landscape project; and
(c) Water budget calculations (optional at the discretion of the City)
for the landscape project.

2.3 Water Efficient Landscape Calculations and Alternatives
(A) The project applicant shall provide the calculated Maximum Applied Water
Allowance (MAWA) and Estimated Applied Water Use (EAWU) for the
landscape area as part of the Landscape Documentation Package submittal to the
City. The MAWA and EAWU shall be calculated based on completing the Water
Efficient Landscape Worksheets (in accordance with the sample worksheets in
Appendix C) which contain information on the plant factor, irrigation method,
irrigation efficiency and area associated with each hydrozone. Calculations are
then made to show that the evapotranspiration adjustment factor (ETAF) for the
landscape project does not exceed a factor of 0.55 for residential areas and 0.45
for non-residential areas, exclusive of Special Landscape Areas. The ETAF for a
landscape project is based on the plant factors and irrigation methods selected.
The Maximum Applied Water Allowance is calculated based on the maximum
ETAF allowed (0.55 for residential areas and 0.45 for non-residential areas) and
expressed as annual gallons required. The EAWU is calculated based on the
plants used and irrigation method selected for the landscape design.
(B) The EAWU allowable for the landscape area shall not exceed the MAWA. The
MAWA shall be calculated using an evapotranspiration adjustment factor
(ETAF) of 0.55 for residential areas and 0.45 for non-residential areas, except for
the portion of the MAWA applicable to any Special Landscape Areas within the
landscape project, which shall be calculated using an ETAF of 1.0. Where the
design of the landscape area can otherwise be shown to be equivalently water -
efficient, the project applicant may submit alternative or abbreviated information
supporting the demonstration that the annual EAWU is less than the MAWA, at
the discretion of and for the review and approval of the local agency.
(C) Water budget calculations shall adhere to the following requirements:
(1) The MAWA shall be calculated using the Water Efficient Landscape
Worksheets and equation presented in Appendix C.
(2) The EAWU shall be calculated using the Water Efficient Landscape
Worksheet and equations presented in Appendix C.
(3) For the calculation of the MAWA and EAWU, a project applicant shall use
the ETo values from the closest location listed the Reference
Evapotranspiration Table in Appendix D. For geographic areas not
covered in Appendix D, data from other cities, or zip codes, located
nearby in the same reference evapotranspiration zone may be used.
(4) For calculation of the EAWU, the plant water use factor shall be
determined as appropriate to the project location from the Water Use
Efficiency of Landscape Species (WUCOLS) Species Evaluation List or
from horticultural researchers with academic institutions or professional
E
3-156
associations as approved by the California Department of water Resources
(DWR). The plant factor ranges from 0 to 0.1 for very low water use
plants, 0.1 to 0.3 for low water use plants, 0.4 to 0.6 for moderate water
use plants, and 0.7 to 1.0 for high water use plants.
(5) For calculating the EAWU, the plant water use factor shall be determined
for each valve hydrozone based on the highest -water -use plant species
within the zone. The plant factor for each hydrozone may be required to
be further refined as a "landscape coefficient," according to protocols
defined in detail in the WUCOLS document, to reflect planting density and
microclimate effects on water need at the option of the project applicant
or the City.
(6) For calculation of the EAWU, the area of a water feature shall be defined
as a high water use hydrozone with a plant factor of 1.0.
(7) For calculation of the EAWU, a temporarily irrigated hydrozone area, such
as an area of highly drought -tolerant native plants that are not intended to
be irrigated after they are fully established, shall be defined as a very low
water use hydrozone with a plant factor of 0.1.
(8) For calculation of the MAWA, the ETAF for Special Landscape Areas
(SLA) shall be set at 1.0. For calculation of the EAWU, the ETAF for SLA
shall be calculated as the SLA plant factor divided by the SLA irrigation
efficiency factor.
(9) Irrigation efficiency (IE) of the irrigation heads used within each
hydrozone shall be assumed to be as follows, unless otherwise indicated
by the irrigation equipment manufacturer's specifications or demonstrated
by the project applicant:

(D) The Maximum Applied Water Allowance shall adhere to the following
requirements:
0
3-157
(1) The Maximum Applied Water Allowance shall be calculated using the
equation presented in Appendix C. The reference evapotranspiration
(ETo) values used for this calculation are from the Reference
Evapotranspiration Table in Appendix D and are for planning purposes
only. For actual irrigation scheduling, automatic irrigation controllers are
required and shall use current ETo data, such as from the California
Irrigation Management Information System (CIMIS), other equivalent
data, or soil moisture sensor data.
2.4 Soil and Stormwater Management
(A) All planted landscape areas are required to have friable soil to maximize retention
and infiltration. On engineered slopes, only amended planting holes need meet
this requirement.
(B) In order to reduce runoff and encourage healthy plant growth, a soil management
report shall be completed by the project applicant, or his/her designee, as follows:
(1) Submit soil samples to a certified agronomic soils laboratory for analysis
and recommendations.
(a) Soil sampling shall be conducted in accordance with laboratory
protocol, including protocols regarding adequate sampling depth
for the intended plants.
(b) The soil analysis may include, but is not limited to:
1. soil texture;
2. infiltration rate determined by laboratory test or soil texture
infiltration rate table;
3. pH;
4. total soluble salts;
5. sodium;
6. percent organic matter; and
7. recommendations.
(2) In projects with multiple landscape installations (i.e. production home
developments or common interest developments that are installing
landscaping) a soil sampling rate of 1 in 7 lots or approximately 15% will
satisfy this requirement; evenly disbursed throughout the development.
Large landscape projects shall sample at a rate equivalent to 1 in 7 lots or
7
3-158
approximately 15% landscape area. The project applicant, or his/her
designee, shall comply with one of the following:
(a) If significant mass grading is not planned, the soil analysis report
shall be submitted to the local agency as part of the Landscape
Documentation Package; or
(b) If significant mass grading is planned, the soil analysis report shall
be submitted to the City as part of the Certification of Completion.
(c) The soil analysis report shall be made available, in a timely
manner, to the professionals preparing the landscape design plans
and irrigation design plans in order to make any necessary
adjustments to the design plans.
(d) The project applicant, or his/her designee, shall submit
documentation verifying implementation of soil analysis report
recommendations to the local agency with the Certification of
Completion.
[Note: Authority Cited: Section 65595, Government Code.
Reference: Section 65596, Government Code.]
[LOCAL AGENCY MAY ADD OR DELETE THE FOLLOWING, (C) -(D), OR MAY ADD
THE SPECIFIC CODE SECTION NUMBERS, OR RELEVANT LAWS AND
REGULATIONS]
(C) It is strongly recommended that landscape areas be designed for capture and
infiltration capacity that is sufficient to prevent runoff from impervious surfaces
(i.e. roof and paved areas) from additional capacity as required by any applicable
local, regional, state, or federal regulation and/or one of the following: the one
inch, 24-hour rain event or the 85th percentile, 24-hour rain event.
(D) It is recommended that storm water projects incorporate any of the following
elements to improve on-site stormwater and dry weather runoff capture and use:
(1) Grade impervious surfaces, such as driveways, during construction to
drain into vegetated areas.
(2) Minimize the area of impervious surfaces such as paved areas, roof, and
concrete driveways.
(3) Incorporate pervious or porous surfaces (e.g. gravel, permeable pavers or
blocks, pervious or porous concrete) that minimize runoff.
.91
3-159
(4) Direct runoff from paved surfaces and roof areas into planting beds or
landscape areas to maximize site water capture and reuse.
(5) Incorporate rain gardens, cisterns, and other rain harvesting or catchment
systems.
(6) Incorporate infiltration beds, swales, basins, and drywells to capture
stormwater and dry weather runoff and increase percolation into the soil.
(7) Consider constructed wetlands and ponds that retain water, equalize
excess flow, and filter pollutants.
[Note: Authority cited: Section 65595, Government Code. Reference:
Section 65596, Government Code.]
2.5 Landscape Design Plan

the climatic, geologic, and topographical conditions of the project site. Methods to
achieve water efficiency shall include one or more of the following:
(1) Use the Sunset Western Climate Zone System, or equivalent generally
accepted models, which takes into account temperature, humidity,
elevation, terrain, latitude, and varying degrees of continental and marine
influence on local climate;
(2) Recognize the horticultural attributes of plants (i.e., mature plant size,
invasive surface roots) to minimize damage to property or infrastructure
(e.g., buildings, sidewalks, and power lines); allow for adequate soil
volume for healthy root growth and
(3) Consider the solar orientation for plant placement to maximize summer
shade and winter solar gain.
(D) Turf is discouraged on slopes greater than 25% where the toe of the slope is
adjacent to an impermeable hardscape and where 25% means 1 foot of vertical
elevation change for every 4 feet of horizontal length (rise divided by run x 100 =
slope percent).

recommendations of the soil report and what is appropriate for
plants selected.
(c) For landscape installations, compost at a rate of a minimum of four
cubic yards per 1,000 square feet of permeable area shall be
incorporated to a depth of six inches into the soil. Soils with
greater than 6% organic matter in the top 6 inches of soil are
exempt from adding compost and tilling.
(d) A minimum three inch (Y) layer of mulch shall be applied on all
exposed soil surfaces of planting areas except in turf areas,
creeping or rooting groundcovers, or direct seeding applications
where mulch is contraindicated. To provide habitat for beneficial
insects and other wildlife, up to 5% of the landscape area may be
left without mulch. Designated insect habitat must be included in
the landscape design plan as such.
(e) Stabilizing mulching products shall be used on slopes that meet
current engineering standards such as those detailed in the
