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 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.

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 April19 , 2016 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 April19 , 2016 Page 4 of 4 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. ATTACHMENTS: A. Ordinance No . 16-101 3 B. Temple City Water Efficient Ordinance Guidelines C.
