AGENDA REPORT
TO: Honorable City Council
FROM: David A. Bobardt, Planning Director
By: Joseph R. Vacca, Principal Plan e •�
i,
DATE: November 12, 2009 (CC Meeting of 12/16/09)
SUBJECT: __ Consider -_an_._.Or_dinance_-A-dding __Chapter. - 15.23---Water—Efficient
Landscape Ordinance to Title 15 of the Municipal Code, Adopting by
Reference the Model Water Efficient. Landscape Ordinance of the
State of California as contained in the California Code of Regulations
Title 23. Waters, Division 2. Department of Water Resources, Chapter
2.7. Model Water. Efficient Landscape Ordinance, Sections 490
through 494
BACKGROUNDIDISCUSSION
In 1992, the State of California enacted the Water Conservation .in Landscaping Act,
(AB 325) requiring the adoption of water efficient landscape ordinances by cities and
counties throughout the state. The California Department of Water Resources (DWR)
developed a Model Water Efficient Landscape Ordinance that established water
efficient landscape design standards for urban landscapes. Cities could adopt the DWR
model ordinance outright, modify it to meet a city's local needs, or adopt an entirely
different ordinance. The City of Moorpark never adopted a local water efficient
landscape ordinance. In 2006, Governor Schwarzenegger signed Assembly Bill 1881
(Laird, Water Conservation) amending the Water Conservation in the Landscape Act
(Act). The bill requires that on or before January 1, 2010, a local agency adopt one of
the following:
(1) A water efficient landscape ordinance that is, based on evidence in the
record, at least as effective in conserving water as the updated model ordinance
adopted by the department; or
(2) The State's updated model water efficient landscape ordinance.
If a local agency has not adopted, on or before January 1, 2010, a water efficient
landscape ordinance, the State's updated model ordinance shall apply within the
jurisdiction of the local agency, and as of that date, shall be enforced by the local
agency, and shall have the same force and effect as if adopted by the local agency.

The State Model Water Efficient Landscape Ordinance, ( MWELO) has been updated to
establish a structure for designing, installing, maintaining and managing water efficient
landscapes in new and rehabilitated projects. The ordinance reduces water use to the
lowest practical amount and sets an upper limit that shall not be exceeded. It also
establishes provisions for water management practices and water waste prevention for
established landscapes. The ordinance intends to promote the values and benefits of
landscapes while recognizing the need to use water and other resources efficiently.
The State's MWELO applies to new and rehabilitated landscape projects that require a
building or landscape permit; plan check or design review when there is 2,500 sq. ft or
more of landscaped area proposed. This applies to public agency projects, (parks,
schools, city properties), private development (retail, industrial, commercial properties)
and developer- installed single - family and multi - family projects (master- planned
com u es . The MWELO also applies to new single- family housing projects (non -
developer), when there is 5,000sq. ft. or more landscaped area for a homeowner or
contractors of single - family and multi- family construction. Registered local, state or
federal historical sites, ecological restoration and mined -land, reclamation projects that
do not require permanent irrigation systems and collections of botanical gardens and
arboretums open to the public are all exempt from MWELO.
The MWELO requires local agency review and approval of landscape documentation
packages which must contain the following items: 1) Project Information, 2) Water
Efficient Landscape Worksheet, 3) Soil Management Report, 4) Landscape Design
Plan, 5) Irrigation Design Plan, and 6) Grading Design Plan. The ordinance also
requires the local agency to review the landscape documentation package for
compliance with MWELO. The local agency is required to ensure that after landscaping
has been installed that the landscape contractor provides a certification of installation
containing soils information, an irrigation and maintenance schedule and an irrigation
audit report prior to the local agency's issuance of a certificate of completion for the
landscaping project. In lieu of drafting an ordinance in an effort to provide requirements
that are at least as effective as the State ordinance, staff proposes adoption of the
State's model ordinance by reference to ensure that Moorpark complies with all of the
parameters set forth in the model ordinance.
An ordinance is attached for Council consideration to adopt the State's updated model
water efficient landscape ordinance by reference. State law requires, after introduction
of an ordinance adopting any State Code by reference, that the City hold a properly
noticed public hearing after introduction and prior to adoption. Staff is requesting the
City Council to direct the advertising of a hearing for the January 6, 2010 regular City
Council meeting.

On September 15, 2004, the City Council adopted Landscape Design Standards and
Guidelines for the City of Moorpark. These guidelines outline landscaping plan
submittal requirements, planting and irrigation standards, the landscaping and irrigation
plan check process, and finally, the certification process for final installation, which
ensures compliance with requirements for irrigation and planting prior to final approval
of a project. Although most of the existing requirements of the City's Landscape Design
Standards and Guidelines are in compliance with the State's new model ordinance,
some updating is needed to address water use. Therefore, staff is also requesting City
Council direction to update to the City's Landscape Design Standards and Guidelines to
ensure consistency with State law. The City Attorney has reviewed and approved this
staff report.
PROCESSING TIME LIMITS
Since - this - ordinance -was- initiated -by -the -City, the - processing -- time - limits- under - -the
Permit Streamlining Act ( Govemment Code Title 7, Division 1, Chapter 4.5), the
Subdivision Map Act (Government Code Title 7, Division 2), and the Califomia
Environmental Quality Act Statutes and Guidelines (Public Resources Code Division 13,
and Califomia Code of Regulations, Title 14, Chapter 3) are not applicable.
ENVIRONMENTAL DETERMINATION
In accordance with the City's environmental review procedures adopted by resolution,
the Planning Director determines the level of review necessary for a project to comply
with the Califomia Environmental Quality Act (CEQA). Some projects may be exempt
from review based upon a specific category listed in CEQA. Other projects may be
exempt under a general rule that environmental review is not necessary where it can be
determined that there would be no possibility of significant effect upon the environment.
A project which does not qualify for an exemption requires the preparation of an Initial
Study to- assess the level of potential environmental impacts.
The Director has reviewed this project and found it to qualify for a General Rule
Exemption in accordance with Section 15061 of California Code of Regulations (CEQA
Guidelines). No further environmental documentation is required.
FISCAL IMPACT
City costs for landscape plan review will be charged to the developer based on actual
review time. Some City staff time will be required to update the Landscape Design
Standards and Guidelines. This can be absorbed within the existing budget.

§ 492A Water Efficient Landscape Worksheet.
(a) A project applicant shall complete the Water Efficient Landscape Worksheet which contains two
sections (see sample worksheet in Appendix B):
(1) a hydrozoae information table (see Appendix B, Section A) for the landscape pwjcct; and
(2) a water budget calculation (see Appendix B, Section B) for the landscape project. For the . calculation
of the Maximum Applied Wad Allowance and Estimated Total Water Use, a project applicant shall use
the ETo values from the Reference Evapotranspiration Table in Appendix A. For geographic areas not
covered in Appendix A, use data from other cities located nearby in the same reference
evapotranspiration zone, as found in the CD&S Reference Evapotranspiration Zones Map, Department
of Water Resources, 1999.
(b) Water budget calculations shall adhere to the following requirements:
(1) The plant factor used shall be from WUCOLS. The plant factor ranges from 0 to 03 for low water
use plants, from 0.4 to 0.6 for moderate water use plants, and from 0.7 to 1.0 for high water use plants.
(2) All water feahnees shall be included in the high water use hydi±ozone and temporarily irrigated areas
shall be included in the low water use hydrozone..
(3) All Special Landscape Areas shall be identified and their water use calculated as described below.
(4) ETAF for Special Landscape Areas shall not exceed 1.0.
(c) Maximum Applied Water Allowance
The Maximum Applied Water Allowance shall be calculated using the equation:
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
8'
19
The example calculations below are hypothetical to demonstrate proper use of the equations and do not
represent an existing and/or planned landscape project. The ETo values used in these calculations are
from the Reference Evapotranspiration Table in Appendix A. for planning purposes only. For actual
irrigation schedulizig, automatic irrigation controllers are required and shall use current reference
evapotranspiration data, such as from the California Irrigation Management Information System
(CWIS), other equivalent data, or soil moisture seam data.
(1) Example MAWA calculation. a hypothetical landscape project in Fresno, CA with an irrigated
landscape area of 50,000 square feet without any Special Landscape Area (SLA= 0, no edible pleats,
recreational areas, or use of recycled water). To calculate MAWA, the animal refm=ce
evapotranspiration value for Fresno is 51 .1 inches as listed in the Reference Evapotranspiration Table in
Appendix A.
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAWA - Maximum Applied Water Allowance (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
-0,62 = Conversion Factor (to' gallons)
0.7 = ET Adjustment Factor (ETAF)
LA = Landscape Area including SLA (square feet)
0.3 = Additional Water Allowance for SLA
SLA = Special Landscape Area (square feet)
MAWA = (51-. 1—ifid s) (0 .62) -((0:7 -K-50;00 0 square feet)-+ (0:3 -1-0)]
= 1,108,870 gallons per year
To convert from gallons per year to hundred-cubio-feet per yeas
= 1,108,870/748 =1,482 hundred-cubicfeet per year
(100 cubic feet = 748 gallons)
(2) In this next hypothetical example, the landscape project in Fresno, CA has the same ETo value of
51.1 inches and a total landscape area of 50,000 square feet Within the 50,000 square foot project there
a now a 2,000 square foot area planted with edible plants. This 2,000 square foot area is considered to
be a Special Landscape Area.
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAWA = (51.1 inches) (0.62) [(0.7 x 50,000 square feet).+ (0.3 x 2,000 square feet)]
= 31.68 x [35,000 + 600] gallons per year
= 31.68 x 35,600 gallons per year
= 1,127,808 gallons per year or 1,508 hundred-cubic-feet per year
(d) Estimated Total Water Use.. '
The Estimated Total Water Use shall be calculated using the equation below. The sum of the Estimated
Total Water Use calculated for all hydrozones shall-not exceed MAWA.
ETWU = (ETo)(0.62�P x +SLA
IE
Where.
ETWU = Estimated Total Water Use per year (gallons)
.ETo = Reference Evapotranspiration (inches)
PF = Plant Factor from WUCOIS (see Section 49 1)
HA = Hydrozone Area Pugh, medium, and low water use areas] (square feet)
SLA = Special Landscape Area (square feet)
0.62 = Conversion Factor
IE = Irrigation Efficiency (minimum 0.71)

The pmjecfs Maxtmwn Applied Water Allowance shall be calculated using this equation:
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)j
where:
MAWA = Maximum Applied Water ANowance (gallons per year)
ETo = Rde 6x* Evapotrar>spkation from Appendix A (inches per year)
0.7 = ETA4udma t Factor (ETAF)
LA = Landscaped Area krdudes Special Landscape Area (square feet)
0.62 = Conversion factor (to gallons per square foot)
SLA = Portion of the landscape area identified as Special Landscape Area (square far=t)
0.3 = the addifional ET Adjustment Factor for Special Landscape Area (1.0 - 0.7 = 0.3)
Maximum Applied Water Allowance = aalbns per year
Show calculations.
If considering Effective Pr tor, use 25% of annual precipitation. Use the following equation to calculate
