is developed on th e reg io nal te mplate of the San Gabriel Council of Governments
(COG), which is based on the MWELO and maintains the effectiveness in implementing
the goals of water conservation. Many neighboring j urisd ictions in the San Gabrie l
V all ey have use d the COG 's te mplate for a loca l WELO. Adopting the proposed WELO
will enable t he City to regulate landscape developments in a manner cons istent with

2.2 Water Efficient Landscape Calculations and Alternatives
(A) The project applicant shall provi d e the ca lcul ated Maximum Applied Water
Allowan ce (MAWA) and Estimated Total Water Use (ETWU) for the
landscape a rea as pa rt o f the Landscape Documentation Pa ckage subm ittal
t o the City. The MAWA and ETWU shall be calcu lated based on
co mpletin g the Water Effi cient Landscape Worksheets (in accordance with
the sa mpl e worksheets in Appendix C) w hich contain informat ion on th e
plant fa ctor, irrigation m eth od, irrigation effici ency an d area associate d
with eac h hydrazone. Calculat ions are th en mad e to show that the
evapotranspiration adjustmen t factor (E TAF) f or th e landscape project does
not exceed a factor o f 0.55 for resident ial a reas and 0.45 for non-
residen ti al areas, excl usive of Special Landscape Areas, w hi ch shall be
ca lcu lated using an ETAF of 1.0. The ETAF for a landscape project is based
on the plant factors and irri gation methods se lected. The Maximum Total
6
Water Allowance is calcu lated based on the ma xi mum ETAF allowed (0.55
for residential areas and 0.45 for non-res identia l areas) and expressed as
an nu al gallons requi red. The ETWU is ca lculated based on the plants used
and irrig ation method se lected for the lan d scape design.
(B) Where the design of the landscape area can otherwise be shown to be
equiva lently water-efficien t , the project applicant may submit alternative or
abbreviat ed i nformation supporting the demonstration that the annual
ETWU is less than the MAWA, at the disc retion of and for t he review and
approval of the loca l agency.
(C) Water budget calcu lations sha ll adhere to the followin g requirements:
(1) Th e MAWA sha ll be calculated using the Water Efficient Landscape
Worksheets and eq u ation presented in Appendix C. The example
calculation on page 27 is a hypoth eti ca l example to demonstrate
proper use of the equation.
(2) Th e ETWU sha ll be ca lcul ated usi ng the Water Efficient La ndscape
Workshe et and equations p rese nted in Appendix C.
(3) For the calculat ion o f th e MAWA a nd ETWU, a project applicant shall

profe ssional assoc iations as approved by the Californ ia Depart ment
of water Resources (DWR). The plant factor ranges from 0 to 0.1 f o r
very low wate r use plants, 0.1 to 0.3 for lo w water u se plants, 0.4 to
0.6 for moderate wa t er use plants, and 0.7 to 1.0 for high wate r u se
plants.
(5) For calcu lat in g th e ETWU, the plant water use factor sha ll be
d etermined for eac h valve hy drazone ba se d on the hi ghest-wate r-
use plant spec ies within th e zone. The plant fa ctor for each
hydrazone may be required to be further refined as a "landscape
coefficient," according to protocols defined in detai l in the WUCOLS
7
document, to reflect planting density and microclimate effects on
water need at t he option of the project applicant or t he City.
(6) For calculation of the ETWU, the area of a water feature shall be
defined as a hig h water use hy drazone with a plant factor of 1.0.
(7) For ca lculation of t he ETWU, a t emporari ly irriga t ed hydrazone area,
such as an area of h ighly 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 hydrazone with a plant factor of 0.1 .
(8) For calculation o f the MAWA, the ETAF for Sp ecia l Landscape Areas
(SLA) shall be set at 1.0. For calculation of the ETWU, the ETAF for
SLA shall be calcul ated as the SLA plant factor divided by the SLA
i rrigation efficiency factor.
(9) Irrigation efficiency (IE) of the 1rngation heads used within each
hydrazone sha l l be ass umed to be as follows, un less otherwise

COMMUNITY DEVELOPMENT DEPARTMENT
MEMORANDUM
DATE: April19, 2016
TO: The Honorable City Council
FROM: Bryan Cook , City Manager
By: Michael D. Forbes, Community Development Director
Hesty Liu , Associate Planner
SUBJECT: INTRODUCTION AND FIRST READING FOR ORDINANCE NO. 16-1013
AMENDING THE TEMPLE CITY MUNICIPAL CODE FOR THE WATER
EFFICIENT LANDSCAPE ORDINANCE (WELO)
RECOMMENDATION:
The City Council is requested to :
1. Introduce , for first reading by title only, Ordinance No . 16-1013 (Attachment "A ")
amending Chapter 1 (Zoning code) of Title 9 (Zoning Regulation) of the Temple
City Municipal Code (TCMC) to establish a Water Efficient Landscape Ordinance ;
2. Adopt the Guidelines for the Water Efficient Landscape Ordinance (Attachment
"B"); and
3. Schedule the second reading of Ordinance No. 16-1013 for May 3, 2016 .
BACKGROUND:
1. In 2006 , the State passed AB 1881 , known as the Water Conservation in
Landscaping Act of 2006 , which requires that a local agency adopt a WELO by
January 1, 2010, or institute the State Model Water Efficient Landscape Ordinance
(MWELO) by default.
2 . On February 11, 2010, city staff sent a letter to the Department of Water Resource
indicating that the City would institute the State MWELO while maintaining the
intention of developing a local WELO at a later time .
City Council

Page 2 of 4
3. On April 1, 2015 , Governor Brown issued the Drought Executive Order directing
th e Department of Water Resources to update its 2009 MWELO to help the State
with the growing water crisis .
4 . On April 28 , 2015, staff presented the draft Temple City WELO to the Plann ing
Commission . The draft WELO was developed based on AB 1881 . Afte r the
Planning Commission meeting, staff suspended th e processing of the WELO due
to the Governor's Executive Order and to await the update to the State MWELO so
th at it cou ld be incorporated into the WELO .
5. On July 15, 2015, the California Water Commission approved the updated State
MWELO . A local agency was required to rev ise or adopt a lo cal WELO by
December 1, 2015 . Or, a local agency could comply with the updated State
MWELO , if no action was taken .
6 . In October of 2015 , the WELO subcommittee of the San Gabriel Valley Counci l of
Government's (COG) Planners Technical Advisory Committee re le ased a regio nal
WELO template . The subcommittee was tasked with developing a regional
template for member cities with th e goal of i ncreasing effi c ie nci es across the San
Gabriel Va l ley and looking at best practi ces throughout the region.
7 . On J anuary 26, 2016 , staff presented to the Plan ning Commission the Temple City
WELO and Guidelines based on the COG 's template . A fter hearing the staff report
(Attachment "C"), th e Planning Commission opened the public hea ring and voted
unanimously to re commend that the City Council adopt the W ELO and the
Guidelines.
8 . On Februa ry 9 , 201 6 , the City Council Water Ad Hoc Committee reviewed the
Templ e City WELO and Guidel in es . Th e Ad Hoc Committee did not recommend
any c han ges and directed staff to proceed to the City Council.
9 . On April 5 , 2016, the City Council continued th e introduction and the first readi ng
for Ordinance No . 16 -101 3 to April19 , 2016 .
ANALYSIS:
Ado pt ing a WE LO is a State statutory requirement. A jurisdiction can adopt the State
MWELO or develop its own version . Any changes to the State MWELO must be "at
least as effective " as th e State MWELO . The propose d WELO is based on the COG 's
template which differs from the State MWELO in the following ways :
City Coun ci l
April 19 , 2016
Page 3 of 4
• Instead of including detailed calculat ions and factors (such as the
evapotranspiration adjustment factor) in the Ordinance , these components are
placed in the WELO Guidelines . From time to time as the State makes further
refinements to the MWELO , staff will be able to administratively modify the
Guidelines. The Guidelines require staff to notify the Planning Commission
regarding changes to the Guidelines ;
• An allowance for landscape architects to self-certify that a plan meets the WELO
and that the installation of the landscaping meets the approved plans . Th is will
reduce project expenses by l imiting the need for landscape and irrigation plans to
go through a separate landscape plan check procedure ;
• An Irri gation Audit wou ld be come an optional requirement; and
• For existing landscape projects that will be rehabilitated with lower water use
plants , a landscape documentation package would be optional , not required .
The above distinctions will not compromise the effectiveness of the proposed WELO ,
and will be at least as effective as the State MWELO (a detailed explanation regarding
effectiveness can be found in Attachment "C", the Planning Commission Staff Report).
The essential goal of the MWELO is to promote water conservation . In light of such a
goal , the changes made by the COG subcommittee will provide an ordinance with
enhanced c larity, streamline the review and approval process , enable the quality of the
projects to be controlled by i ndustry standards and landscaping professionals , and
encourage the existing landscapes to be converted to low water use through exempting
the requirement of providing the Landscape Documentation Package for small projects .
The proposed ordinance , if adopted , will meet the "effectiveness " criterion of the State
and be consistent with the regulations of many neighboring jurisdictions in the San
Gabriel Va lley .
Findings
TCMC Section 9 -1 G-0 provides that the Zoning Code may be "amende d wh e ne ver the
public in te rest and necessity so requ ire." There are no specific f i ndings required to
am e nd th e Zoning Code or oth e r t itles of the Mun icipal Code . T[le proposed Ordinance
is consiste nt with the exi stin g and propo sed Ge ne ral Plan .
City Council

Environmental Review
The proposed ordinance is exempt from environmental review under the California
Environmental Quality Act (CEQA) pursuant to Section 15307 of the CEQA Guidelines
because it is an action of "regulatory agencies for protection of natural resources ".
CITY STRATEGIC GOALS:
Adopting the proposed ordinance would further the City Strategic Goals of Sustainable
Infrastructure.
FISCAL IMPACT:
The proposed ordinance would have no impact on the Fiscal Year 2016-17 City Budget.
