The City of Vernon entered into an agreement with Civitech Engineering, Inc, (Civiltech) to prepare the 2010 UWMP. Civiltech has completed the preparation of the UWMP in accordance with the. provisions of the California Urban water Management Planning Act. Moreover; the UWMP is intended toserveas a long-range planning document for water supply, a - source of data for development of a regional water plan, and a source document for cities and counties as they: prepare their General Plans. The main components of the UWMP include water delivery and uses, water supply sources, efficient water uses, implementation strategy and schedule for demand management measures, baseline, interim and compliance with daily per capita water use, water supply availability to meet existing and futuredemands, and water shortage and drought contingency planning. The UWMP was originally due for submittal to the Department of Water Resources (DWR) on December 31, 2010. However, recently adopted Senate Bill 7 (SB 7) granted all urban water retailers an extension until July 1, 2011 for the completion of the 2010 UWMP, in order to ensure that all new legislation requirements are incorporated. SB 7 includes the Governor's 20x2020 mandatory conservation goals and requires all urban water retailers to comply with interim per capita water, reductions by July 1 2016, or else risk losing eligibility for state water grants and loans. In addition, Assembly Bill 1420 also links additional funding sources to UWMP components. A Public Hearing will be held on May 17, 2011, to solicit comments from the public in regards to the adoption of the UWMP. Enclosed is a copy of the UWMP for Council review. It is my recommendation that the 2010 UWMP be adopted at the May 17, 2011, City Council meeting. Thank you.

This 20Lt1F` Urban Water nagemei lW. an for the City of Vernon (UWMP) has been prepared ; in fulfillment of the requireme of the Ca�hoinAt ta Urban Water Management Planning Act (Act) and in compliance with the Cruidebo�ol'to Assif'Water Suppliers in the Preparation of a 2010 Urban Water Management': (Guidebook) rovided by the California Department of Water Resources (DWR). 010 The Guidebook pr`vtdes guida 01I respective to the minimum requirements of the California Urban Water Management Planning Aet an Ithe recent legislative changes and amendments embodied in the California Water Conservation Act' v�' 2009 and AB 1420 which more narrowly defines eligibility for water _f management grants and loans. In addition to compliance with state mandate, this UWMP is a living document whose contents fulfill a variety of planning, informational and legal requirements. It will serve as a primary source for integrated water and land use planning at the district, city and county levels per compliance with SB 610 and SB 221 related to water assessment and procurement of water supplies prior to construction of new development. The accuracy, clarity, completeness and usefulness of this UWMP is defensible and representative of the City's.best understanding of the state of water management at the time of adoption and/or amendment. To . that end, all aspects of water management as they pertain to the City have been delineated in order to provide developers, planners, government agencies and its customers with the tools they need to fulfill their individual missions and interests. KK..A . 2010 URBAN WATER MANAGEMENT PLAN engitte�rii�g tt¢ 6 V CHAPTER ONE — INTRODUCTION CITY O V F;It. t�� Substantial growth in the State of California is projected by the State Department of Finance, and there is no end in sight. The challenge facing water agencies, public agencies, planners and project proponents is to identify and secure the sources of water needed for the inevitable increase in population. From a water resources point of view, planning for such growth is addressed by SB 610, SB 221 and related jurisdictional General' Plans. Cities, counties, water districts, property owners, and developers will all be able to utilize the UWMP when planning for and proposing new `projects. For certain'"projects" meeting the definitions. under SB 610 and/or SB 221, a city or county evaluating the environmental effects of;that project must request a Water Supply Assessment (WSA) from the water provider or prepare the WSA on its own. AWSA can rely on an adopted and DWR-approved UWMP making the UWMP a foundational document for compliance` with both SB 610 and SB 221. Both of these statutes repeatedly identify the UOMkas a planning document that, if properly prepared, can be used by a water supplier to meet the sta ds set forth in both statutes: A thorough and complete UWMP will allow the City to use the UWMP i, N ridation to fulfill the specific requirements of these two statutes. SB 610 creates a strong link between water supply availability nt land use by requ fng:cities and counties toconsider water availability for certain development pr. . cts: It promotes collaboration between local water suppliers and cities/counties while recognizing tl t portance flocal control an edsion making regarding water availability. 0 VNEW� N SB 221 requires written verification of sufficient water a from the water supplier prior the construction of residential subdivisions ofkater than 500 dweunits. A sufficient water supply" includes assessment of the water supplier'sle projected wateflies for a 20-year period during normal years, single -dry years and multiple dz �yd s This assessment�tnusf consider the subdivision's water demands in addition to existing and planne future'-- ands. The UWMP serves as an important source document four cities and counties as they update their General Plans. Conversely, Genera).Flans�ar ource documits as water, suppliers update their UWMPs. These ' planning documents areA ked andtlteir accuracy ad usefulness are interdependent. It is crucial that cities, counties and wafeMppliers wok closely when dl& I ping and updating these planning documents. ! k.Hgg 1&3.- To assishe reader in" uoff%tandm`g elegal mandates involved in the various aspects of this UWMP, releva tad applicable exc s for th G it I is Water Code (CWC) are provided immediately' following each�'ec , P eading.

The Central Basin is bounded on the north by a surface divtde�lled the La Breiigh; and on northeast and east by emergent less permeable Tertiary rocks of the Elyk@eepetto, Merced and Puente Hills. The southeast boundary between Central Basin and Orange CountyfflRundwaf`er Basin roughly follows Coyote Creek, which is a regional drainage province boundary. Th sq iiwest boundary is formed by the Newport Inglewood fault system and the associated folded rocks We Newport Inglewood uplift.

C 20.10t.RDANWATEMIMAi�t,�.(9I�:NIE E PLAN ertgiu�rn nc 23 CHAPTER FOU --- SYSTEM SUPPLIES CITY OF VERNON Throughout the Central Basin, groundwater occurs in Holocene and Pleistocene age sediments at relatively shallow depths. The Central Basin is historically divided into forebay and pressure areas. The Los Angeles forebay is located in the northern, part of the Central Basin where the Los Angeles River enters the Central Basin through the Los Angeles Narrows from the San Fernando Groundwater Basin. The Montebello forebay extends southward from the Whittier Narrows where the San Gabriel River encounters the Central Basin and is the most important area of recharge. Both forebays have unconfined groundwater conditions and relatively interconnected aquifers that extend up to 1,600 feet deep to provide recharge to the aquifer system. The Whittier area extends from the Puente Hills south and southwest to the axis of the Santa Fe Springs -Coyote Hills uplift and contains up to 1,000 feet of freshwater -bearing sediments. The Central ;Basin pressure area is the largest of the four divisions, and contains many aquifers of permeable sands and gravels separated by semi -permeable to impermeable sandy clay to clay, that ;extend to about 2,200 'feet below the surface. Throughout a tmuch of the Central Basin, the aquifer enfined, but 'areas with semipermeable aquicludes allow some interaction between the aquifers �a The main productive freshwater -bearing sediments are containedtWithm �o ocene alluvium and the Pleistocene Lakewood and San Pedro Formations.

In 1959, the State U01" I ture • 3 acted the Water Replenishment Act, enabling the formation of the Water Replenishment Dihem California (WRD) as it is now known to be the permanent agency in charge of replenishing NO,, 'the Central and West Basins. The State Legislature has vested in WRD the statutory responsibility=to manage, regulate, replenish and protect the quality of groundwatersupplies within it boundaries, of which the City of Vernon is included. The Central Groundwater Basin became an adjudicated basin in 1966 (see Appendix I). The Los Angeles County Superior Court oversees the adjudication and the California Department of Water Resources (DWR)'serves as the court appointed watermaster. The Court established groundwater pumping rights at the time of adjudication, and the total allowable' extractions from the basin in a given year are 217,367 acre feet. Central Basin producers may also carry over up to 20 percent of the allowable pumping rights to the next fiscal year. grieerang 25 CHAPTER FOUR - SYSTEM SUPPLIES CITY OF VERNON Maintenance of the basin and the groundwater pumping allocation requires: recharging; accomplished through facilities operated by the Los Angeles County Department of Public Works (LADPW). The groundwater basin is replenished with four sources of water: import supplies from Metropolitan Water District of Southern California(MWD), local run-off from storm flows, allocations from the ,Upper San Gabriel Groundwater Basin, and recycled wastewater from the Los Angeles CountySanitation Districts. The WRD purchases import supplies and recycled water for groundwater replenishment and seawater intrusion` barriers: The City of Vernon has adjudicated groundwater basin rights of 81039 acre-feet per year (AFY). With additional groundwater leases and carryover from previous years, the actual allowable extraction can exceed 8,039 AFY. As with all retailers in the CBMWD, the City is allowed to carry, over its unused allocation of up'to 20%of its adjudicated rights to the next fiscal year. F During a declared water shortage, the Central Basin Watermaster may iRI wk e`Cityto over -pump 20%of its water rights; however, in doing so it must decrease its allocationfi 20%l = llowing fiscal year. With this arrangement, the City can sustain itself during a declared w erortage in MC manages its supply so that when additional water is needed, due to the possibil` -of a shortfall r imported supply, these groundwater rights can be exercised. � Table 10 shows the volume of water pumped annually 4om the Central f asin for the last fl01tyears.

The City should ensure that the industries within these zones are aware`�that they have the potential to impact the City's groundwater supply. Historical data provided by the City showed evidence of pumping levels being recorded instead of true static levels. In order to obtain static levels; it is recommended that the well pump be turned off for at least six hours prior to a level being recorded. The 'amount of recovery time allowed before.each measurement should also be recorded together with the depth to water. A Installation of a permanent pressure transducer is recommended in each well where one doesn't already exist to collect groundwater level measurements. Access into the wells may be a problem in some instances where the pump base does not have port access for sounders. Possibilities to C4,. x 2010 URBAN W;A'rER MAN,x(,EMENT PLAN -!"

To assist in groundwater, management .of the City's groundwater resources, a Groundwater Monitoring and Management' Plan is an essential document- that incorporates a standard methodology for the collection of data in sufficient quantities and of adequate quality to enable informed decisions regarding the'management of the, groundwater resources in the City's service area. The types of data to be collected include' groundwater levels, groundwater production, and groundwater quality. For on -going groundwater management, a groundwater flow mode uld be developed for the City area. The model can be used to predict the actual interferenc fieckkbetween wells, evaluate groundwater flow direction changes due to pumping, ground level changes in response to various operational scenarios and potential movemenants using particle tracking. The flow model could also be used to predict future groundwater condtns for up to 20 years into the future.

To that end, the City has previously completed the task, in coordination with CBMWD, of evaluating potential recycled water use within the service area as a precursor to continued development of the Southeast WaterReliabilityProject. Special care was taken to exclude potential recycled water use from various industrial processes involving food processing. Vernon is satisfied that CBMWD, who is the lead agency in the Central Basin for the development' and distribution of recycled water, is aware of all potential recycled water use within the service and that CBMWD makes use of this knowledge in the justification for the expansion of the recycled water system, future rate structure and phasing of mplementation. 4.5.1 Disposition Of WasteNvater Collection and Treatment Per the 2009 Vernon General Plan, the City owns its own sewage cection a em which discharges into the system managed by the Los Angeles County Sanitation Distr ctsiLACSD) she majority of Vernon is within District 23, but also contains territory in Districts i and�iIhese Districtsaig with more than a dozen others, are signatories to the Joint Outfall SystextJOS) which provides operation and maintenance of an interconnected system of wastewater q �lection, treatment, reuse, an ispoal facilities across a large portion of the urban region.

CBMWD is responsible for ensuring compliance with State and federal drinking water, regulations with respect to the water it delivers.to Vernon. In addition, CBMWD assists the Central Basin purveyors, including Vernon, to meet drinking water standards with respect to groundwater quality through its Cooperative Basin -Wide Title 22 Groundwater Quality Monitoring Program. Title 22 refers to the California Code of Regulations; pertaining to domestic and recycled water standards. A significant portion of water resources in Vernon are drawn from the groundwater basins that underlie the City and surrounding lands.

CITY OF V 1 R`1ON activities both in Vernon and other cities may affect the quantity and quality of local ` groundwater. Potential contamination and depletion .of the underground basins have been historic concerns, and conditions are continuously monitored to guard against possible interruption of supply, Water quality standards established by federal and State agencies and requirements for water quality monitoring protect end users from contamination and ensure reliable drinking water supplies. In particular, National Pollution Discharge Elimination Systems (NPDES) requirements enforced by the State Regional Water Quality Control Board necessitate the control and clean up of surface runoff prior to its direct discharge into storm drain systems and, ultimately into groundwaterbasins or surface waters. State agencies continue to press for percolation as a means of reclaiming storm water runoff, both as a mechanism to replenish aquifers and to allow for continued natural cleaning- rocesses. Given Vemon's built -out condition and the severe lack of open space, local clean-up and re ; "arge,via percolation proves difficult. In general, the groundwater quality in the aquifers in which the pr6&cti6ti r�l s are screened is relative good. The only naturally occurring constituent of concern is mangy anese. w ' minor localized water quality, concerns are problems related to the color of the groudaeraid relative �h iron content.

Minimum requments were outlined in this Ordinance to protect the water, supplies and to establish standards for"reductions in the use of water in the City of Vernon. The City's "Water Conservation" code was. further amended' in 2006 through the adoption of City Ordinance No. 1115 (Appendix G). Continuing the City's proactive approach to water conservation, the City recently adopted Ordinance No. 1161 (Appendix H) in October 2009, which further expanded the City's water conservation efforts by amending Article VI of Chapter 25 of the Code of the City of Vernon. This Ordinance established general' water waste provisions, as well as conservation measures for Phase I, Phase II and Phase III water shortages. These shortages equate to water supply deficiencies of 206/o, 30% and 50% and greater, respectively. The City has developed a three stage rationing plan to invoke during declared water shortages, in addition to specific water waste provisions mandated regardless of supply conditions. The rationing plan includes mandatory rationing in order to obtain the associated customer reduction goal. 2010 URBAN WATER MANAGEil ENr PLAN engirteeiiyg iitc 41 r MiPPLY RELIABILITY CHAPTER IVE WATER CITY OF VERNON 5.5.1 Rationing Stage During declared shortages, or when a shortage declaration ,appears imminent, Ordinance No. 1161 establishes conservation. measures for Phase I,Phase II and Phase III water shortages.

A more definitive assessment of DMM effectiveness will be for(llcoming following completion of the CUWCC BMP Activity and Coverage Reports for FY 2009-10 a d FY 2010-11 In the meantime, Vernon offers the following assessment. The majority of DMMs are tailored toward residential and irrigation water uses. These water uses are virtually non-existent in Vernon, and the related savings has either already been achieved or is negligible. Administrative' programs aimed at influencing behavior have minimal impact since most water use in Vernon is a business expense and many business owners already minimize this expense internally. The DMMs that show the greatest potential for water savings are DMM 3 (System water audits, leak detection, and repair), DMM 9-(Conservation programs for CII accounts) and DMM 13 (Water waste prohibition). The City estimates that 4% of total potable supply will be achieved through aggressive implementation of DMM 3. MDDs 9 and 13 more directly impact the; commercial and industrial sectors and the City estimates a water use savings for each of about 1% of commercial and industrial demand.

The earth has never been at: a constant temperature. It is either cooling (glacial periods) or warming (interglacial periods) naturally for reasons not completely understood. Sea levels rise'and fall in response to massive ice sheets forming and melting over cycles of tens of thousands of years or more. Over the past 800,000 years, twenty different glacial/interglacial periods have been defined resulting in sea level highs and lows. During the peak of the last ice age (18,000 to 20,000 years ago), geologic 203fpce indicates that the sea level was 400 feet lower than it is today. Since then, the earth has been wa mg, the ice has been melting, and sea levels have been rising at the rate of about 2 inches per century. Until recently, another debate was whether, or not climate than e was berm used in part by human activities. In the opinion of the EPA and the United Nations, ost of_the wa n recent decades has probably been caused by human activities. Over the past v.0 years since the 1 ."a] revolution, the burning of fossil fuels and deforestation have:caused concentrations of heat trng'greenhouse gases" (such as carbon dioxide, methane, and mtrou ide) to mcrt3 e significantly rn atmosphere, preventing heat from escaping to space, thus warmin �lre arth y✓bat like the g s ¢panels of a greenhouse. This 'extra heating has contributed to the not g" tin cycle of the arth, and model gr g �5 g Y predictions are for California to have temperature increases of 2. - degrees Celsius by 2100. Per DWR (July 2006), the potential impacts an�ected consequent climate change on the State's water supply are summarized in Table 22... .

CITY OF VERNON 1 Gener-ol Description The Urban Water Management Planning Act (Act) was adopted in 1983 and may be found in the California Water Code, §§ 10610-10656 (see Appendix A). The City of Vernon is obligated to prepare and adopt this Urban Water Management Plan (UWMP) in the manner specified in the Act by virtue of meeting the statutory definition of an "urban retail water supplier": §10608.12(p) "Urban retail water supplier" means a water supplier, either publicly or privately owned, that directly provides potable municipal water to more than 3,000 end users or that supplies more than 3,000 acre-feet of potable water annually at retail for municipal purposes. The Act, and elements of the California Water Conservation Act of 2009, require urban water suppliers to report, describe, and in some cases evaluate: water deliveries and uses water supply sources efficient water uses implementation strategy and schedule for demand management measures baseline, interim and compliance daily per capita water use water supply availability to meet existing and future demands ® water shortage and drought contingency planning 1.2 Purpose This 2010 Urban Water Management Plan for the City of Vernon (UWMP) has been prepared in fulfillment of the requirements of the California Urban Water Management Planning Act (Act) and in compliance with the Guidebook to Assist Water Suppliers in the Preparation of a 2010 Urban Water Management Plan (Guidebook) as provided by the California Department of Water Resources (DWR). The Guidebook provides guidance respective to the minimum requirements of the California Urban Water Management Planning Act and the recent legislative changes and amendments embodied in the California Water Conservation Act of 2009 and AB 1420 which more narrowly defines eligibility for water management grants and loans. In addition to compliance with state mandate, this UWMP is a living document whose contents fulfill a variety of planning, informational and legal requirements. It will serve as a primary source for integrated water and land use planning at the district, city and county levels per compliance with SB 610 and SB 221 related to water assessment and procurement of water supplies prior to construction of new development. The accuracy, clarity, completeness and usefulness of this UWMP is defensible and representative of the City's best understanding of the state of water management at the time of adoption and/or amendment. To that end, all aspects of water management as they pertain to the City have been delineated in order to provide developers, planners, government agencies and its customers with the tools they need to fulfill their individual missions and interests. w 20I01 ItBAN bi A 1KIt NIANAGI Mt: NT 1'LAN engir�aerir�ginc 6 Substantial growth in the State of California is projected by the State Department of Finance, and there is no end in sight. The challenge facing water agencies, public agencies, planners and project proponents is to identify and secure the sources of water needed for the inevitable increase in population. From a water resources point of view, planning for such growth is addressed by SB 610, SB 221 and related jurisdictional General Plans. Cities, counties, water districts, property owners, and developers will all be able to utilize the UWMP when planning for and proposing new projects. For certain "projects" meeting the definitions under SB 610 and/or SB 221, a city or county evaluating the environmental effects of that project must request a Water Supply Assessment (WSA) from the water provider or prepare the WSA on its own. A WSA can rely on an adopted and DWR-approved UWMP making the UWMP a foundational document for compliance with both SB 610 and SB 221. Both of these statutes repeatedly identify the UWMP as a planning document that, if properly prepared, can be used by a water supplier to meet the standards set forth in both statutes. A thorough and complete UWMP will allow the City to use the UWMP as a foundation to fulfill the specific requirements of these two statutes: SB 610 creates a strong link between water supply availability and land use by requiring cities and counties to consider water availability for certain development projects. It promotes collaboration between local water suppliers and cities/counties while recognizing the importance of local control and decision making regarding water availability. SB 221 requires written verification of sufficient water supply from the water supplier prior the construction of residential, subdivisions of greater than 500 dwelling units. A -"sufficient water supply" includes, assessment of the water supplier's available projectedwater supplies for a 20-year period during normal years,, single -dry years and multiple -dry years. This assessment must consider the subdivision's water demands in addition to existing and planned future demands. The UWMP serves as an important source document for cities and counties as they update their General Plans. Conversely, General Plans are source documents as water suppliers update their UWMPs. These planning documents are linked and their accuracy and usefulness are interdependent. It is crucial that cities, counties and water suppliers work closely when developing and updating these planning documents. 3 Org ti Lnatio To assist the reader in understanding the legal mandates involved in the various aspects of this UWMP, relevant and applicable excerpts for the California Water Code (CWC) are provided immediately following each section heading. These excerpts are cited by CWC section designation and offset in italic print to differentiate them from other text. In general, the chapters of this UWMP are laid out as presented in the Guidebook along with recommended tables and other content. L4 Coordination §10620(d)(2) Each urban water supplier shall coordinate the preparation of its plan with other appropriate agencies in the area, including other water suppliers that share a common source, water management agencies, and relevant public agencies, to the extent practicable. §10621(b) Every urban water supplier required to prepare a plan pursuant to this part shall, at least 60 days prior to the public hearing on the plan required by Section 10642, notes any city or county within which the supplier provides water supplies that the urban water supplier will be reviewing the plan and considering amendments or changes to the 20Ii1 L'E2i3.Ad �T4', 9't :xN engineeriguxe � CHAPTER ONE --- .

The urban water supplier may consult with, and obtain comments from, any city or county that receives notice pursuant to this subdivision. §10635(b) The urban water supplier shall provide that portion of its urban water management plan prepared pursuant to this article to any city or county within which it provides water supplies no later than 60 days after the submission of its urban water management plan. To be completed as agency coordination proceeds. Table 1— Coordination with Appropriate Agencies 1_5 Review. §10642 Each urban water supplier shall encourage the active involvement of diverse social, cultural, and economic elements of the population within the service area prior to and during the preparation of the plan. §10642 Prior to adopting a plan, the urban water supplier shall make the plan available for public inspection and shall hold a public hearing thereon. Prior to the hearing, notice of the time and place of hearing shall be published within the jurisdiction of the publicly owned water supplier pursuant to Section 6066 of the Government Code. The urban water supplier shall provide notice of the time and place of hearing to any city or county within which the supplier provides water supplies. A privately owned water supplier shall provide an equivalent notice within its service area. 20.10I f211A W 1 U.R N A .M.IV MENT i'I.,AN crigitirzrimg inc 8 u CITY OF VERNON ,¢10645 Not later than 30 days after filing a copy of its plan with the department, the urban water supplier and the department shall make the plan available for public review during normal business hours.

These notes will be provided as an appendix to the UWMP. t.6 Adoption §10621(c) The amendments to, or changes in, the plan shall be adopted and filed in the manner set forth in Article 3 (commencing with Section 10640). §10642 After the hearing, the plan shall be adopted as prepared' or as modified after the hearing: To be completed following the final review process. Provide a copy of the adoption in an appendix. 1. % Subinittal §10644(a) An urban water supplier shall submit to the department, the California State Library, and any city or county within which the supplier provides water supplies a copy of its plan no later than 30 days after adoption. Copies of amendments or changes to the plans shall be submitted to the department, the California State Library, and any city or county within which the supplier provides water supplies within 30 days after adoption. §10608.20 A 6-month extension has been granted for submittal of the 2010 UWMPs to provide additional time for suppliers to address the requirements for a 20% reduction from the "baseline daily per'capita water use" by Dec. 31, 2020. To be completed prior to submittal, IX Onfiale Mrta Subrtail:tal DWR is establishing an online data submittal portal for urban water suppliers. Suppliers will be able to go online and complete tables and download them into their plans. The portal, referred to as DOST (DWR Online Submittal Tool), will have an audit system to allow suppliers to double check they have submitted all the data. Suppliers who 'use the online data submittal system and have a state water grant or loan or have submitted a grant proposal will receive priority review. DWR sees on line data submittal as a way to speed up reviews, better manage the data received, standardize data reporting, and enable a direct linkage to the data used to prepare the California Water Plan.

DWR): Vernon City Council Los Angeles County Gateway Alliance I,I.0 judicial Review Any actions or proceedings to invalidate the decisions of an urban water supplier on the grounds of non- compliance with the UWMP Act must be commenced as follows: 90-Day Rule: Any action alleging that a plan, or action taken pursuant to the plan, does not comply with the UWMP Act must be commenced within 90 days after filing of the plan or amendment thereto with DWR. 6 18-Month Rule: Any action alleging failure to adopt a plan must be commenced within 18 months after that adoption is required by the UWMP Act. In challenging the plan's compliance with the UWMP Act, judicial review is limited to whether there was a prejudicial abuse of discretion. These abuses are limited to the supplier not proceeding in a manner required by law or the plan not being supported by substantial evidence (§ 1.0651). The UWMP standard of judicial review was established per Sonoma County Water Coalition, et al. v. Sonoma County Water Agency, California Court of Appeal for the Fourth District, Case No. A124556 (October 8, 2010) as: "In technical matters requiring the assistance of experts and the study .of marshaled scientific data as reflected herein, courts will permit administrative agencies to work out their problems with as little judicial interferences as possible. " This means that the court acknowledges the complexities of collecting and interpreting data related to water supply and demand and defers to the knowledge of the water supplier and expertise of consultants providing their services on the supplier's behalf. No additional standards were deemed necessary by the court to validate conclusions related to collection and interpretation of data. In addition to diligence in data collection and interpretation, care was taken to present this UWMP as a legal document paying particular attention to the following areas of emphasis in order to avoid becoming a target for litigation: 6 Expect this UWMP to be a litigation target. 6 Disclose all physical and legal regulatory factors affecting projected availability of existing and planned future sources of water supply.

The most striking discrepancy is the ratio of employees to residents at more than 400 to one. This exemplifies the nature of the City as a center for commercial and industrial activity which is consistent with the City's mission of "maintaining Vernon as an ideal location for industry in Southern California" per the 2009 Vernon General Plan. Vernon was founded and incorporated in 1905 by James J. and Thomas J. Furlong, both ranchers, and John B. Leonis, rancher and merchant. John Leonis was of Basque origin, coming to Southern California in 1880 to work for his uncle Miguel Leonis whose original 1862 adobe dwelling in Calabasas was designated ;C 2410 L':RBA'ti Wk7EI; LVlAN4kGi M1i3',N'r PLAN ei�gineer•1r� inc 15 G CHAPTER W1 SYSTEMDESCRIPTION. �G 44 /'RlY lk�s. CITY O VERNON City of Los Angeles Cultural -Historic Monument P 1. John Leonis established his own ranch on unincorporated county land southeast of Downtown. Recognizing the significance of the three major railroads running through the area, he convinced railroad executives to run spur tracks off the main lines and incorporated the adjacent three miles as an "exclusively industrial" city named after a dirt road, Vernon Avenue, crossing its center. While waiting for industry to develop in the area, the founders of the city thought of marketing Vernon as a "Sporting Town." In 1907,.on land ]eased from Leonis, Entrepreneur Jack Doyle opened what was billed as the "longest bar in the world." It had 37 bartenders, 37 cash registers and a sign advising "if your children need shoes, don't buy booze." Next door Doyle opened the Vernon Avenue Arena where 20- round world championship fights were held starting in 1908. Soon after, the Pacific Coast (baseball) League built a ballpark with its ]eft field corner abutting Doyle's bar and its own entrance into the park. The Vernon Tigers won three Consecutive league pennants. Last call for Doyle's Bar was June 30, 1919 when over 1,000 people swilled their last pre -Prohibition drink. The chamber of commerce now sits atop Doyle's onetime empire. After 1919, Vernon went back to being exclusively industrial. Two giant stockyards, one mmied by John Leonis, opened with meat packing quickly becoming Vernon's signature industry. Twenty-seven slaughterhouses lined Vernon Avenue fi•om Soto Street to Downey Road until the late 1960s. Said one longtime Boyle Heights Resident, "we could sniell Vernon in the evenings at our home." In the 1920s and 30s, heavy industries such as steel (U.S. and Bethlehem), aluminum (Alcoa), glass (Owens), can -making (American Can) and automobile production (Studebaker) grew in the City. The 1940s and 50s added aerospace contractors (.Norris Industries), box and paper manufacturers, drug companies (Brunswig), and food processors (General Mills, Kal Kan). Giant meat packers (Farmer John and Swift) continued to grow. A strong, unionized labor force meant excellent middle class incomes for thousands of families. In 1932, the City differed with Southern California Edison over industrial rates for Electricity, John Leonis orchestrated.a Vernon bond measure to authorize the construction of the. city's own Light & Power plant, which is still operational .today. Low-cost power and water, along with low taxes, attracted businesses to Vernon. .Later, economical factors including, the free flow of capital and labor across borders had, by 1980, utterly transformed Vernon',s industrial face. The City's signature businesses, the slaughterhouses, relocated. Lower -cost producers in the East and Midwest reduced meat packing plants from 27 to today's two. Bethlehem and US Steel competed unsuccessfully with .European and Asian suppliers. Studebaker and American Can are closed. Defense cutbacks negatively impacted Alcoa and Norris industries. Today smaller industrial/commercial establishments including fashion design, garment -making, .film production, electronics, and waste recycling are characteristic of the business community in Vernon. Information and data provided by the California Department of Finance, Southern California Association of Governments, and applicable city and county general plans will be summarized and analyzed here.

Currently, 90.7% the City's water supply is delivered to the commercial and industrial sectors, and 8.7% is dedicated to power generation. The remaining fraction of 1% of supply is delivered to the residential and institutional sectors. The City has no agricultural or landscaping users. Due to the nature of Vernon as a center of commercial and industrial activity, water demand within the city is linked to the impacts of the marketplace on the region and beyond. For this reason, there is still potential for increases in water demand despite being built -out. Water demand in the commercial and industrial sectors is linked more directly to intensity and productivity than to the size or needs of the local population. Furthermore, Vernon's infrastructure is designed to meet the needs of the commercial and industrial sectors in general whatever they may be, rather than being limited to the specific needs of its current customers. As such, the infrastructure is very robust and adaptable making it capable of meeting the changing requirements necessary to fulfill its mission of being an "ideal location for industry". Therefore, Vernon has.an obligation to have a system in place capable of meeting the demands associated with high intensity and productivity in the commercial and industrial sectors whenever those demands arise as dictated by economic factors that are largely outside of the city's control. uv Mist{ l; l�r'z$t °Demands §10631(e)(1) and (2) Quantify, to the extent records are available, past and current water use, and projected water use (over the same five-year increments described in subdivision (a)), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following uses (A) Single-family residential; (B) Multifamily (C) Commercial; (D) Industrial; (E) Institutional and governmental; (F) Landscape; (G) Sales to other agencies; (H) Saline water intrusion barriers, groundwater recharge, or conjunctive use, or any combination thereof- (I) Agricultural. The availability of data related to consumption by end users for complete calendar years of the detail requested above is limited to the period of 2007 through 2010 which coincides with the implementation of new billing software. For this reason, Table 4 deviates from the typical and preferred 5-year increment.

DEMANDS CITE' (i1~ VERNON '..,� 3,3 ProJected Water Demands §10631(k) Urban water suppliers that rely upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source. of water in five-year increments to 20 years or as far as data is available. The wholesale agency shall provide information to the urban water supplier for inclusion in the urban water supplier's plan that identifies and quantifies, to the extent practicable, the existing and planned sources of water as required by subdivision (b), available from the wholesale agency to the urban water supplier over the same five: year increments, and during various water year types in accordance with subdivision (c). An urban water supplier may rely upon water supply information provided by the wholesale agency in fulfilling the plan informational requirements of subdivisions (b) and (c). §10631.1(a) The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier. Projected water use as shown in Table 5 is based on the following assumptions: Current assumptions: Residential water use is based on the average demand per person for 2007 through 2010 and projected population per the 2009 Vernon General Plan. Commercial and industrial demands are base on corresponding demands in 2007 which are the highest demands in these sectors on record. These are the closest historical data to the concept of complete build -out and 100% occupancy. Actual demand in these sectors is closely linked to the fluctuation of the national and global economies. A national and global economic analysis was considered to be beyond to scope and intent of the Urban Water Management Planning Act and the California Water Conservation Act. As a result, the City of Vernon has an obligation to plan for demands associated with peak economic activity which may occur at any time. Institutional and governmental demands are closely associated with the demands of the City government which are considered to be static. The average demand for this sector for 2007 through 2010 was applied to the associated projection. Recycled water demand is based on the projected requirements of existing and planned power plants whose cooling and process water needs will be met by recycled water per the 2009 Vernon General Plan. System losses are assumed to be 5% of total demand. This projection may be too aggressive and will be adjusted upon further research of associated BMP's currently instituted maintenance programs.

Honsing ;seeds ssess-raeiat In July 2007, the Southern California Association of Governments adopted the final 2006-2014 Regional Housing Needs Assessment which included a future housing allocation of zero in the City of Vernon, which is consistent with previous allocations for the City. Per the Vernon General Plan, future housing growth has been deemed inappropriate due to the City's pervasive industrial environment and land use incompatibilities related to hazardous materials, background contamination, noxious odors, noise pollution, and truck and railroad traffic. 3.6 Application of flit Water Conservation Act. §10608.20(e) An urban retail water supplier shall include in its urban water management plan ... due in 2010 the baseline daily per capita water use, urban water use target, interim urban water use target, and compliance daily per capita water use, along with the bases for determining those estimates, including references to supporting data. Civiltec will defer to the collective determination of the Gateway Alliance regarding application of the California Witter Conservation Act. It is Civiltec's opinion that Vernon cannot comply with the provision of file Act as all independent supplier and must be part of an alliance in order to satisfy the conditions imposed by the Act, In 2009, a number of cities in the Los Angeles Gateway Region (Gateway Region) and other interested parties formed an official joint powers authority (JPA) to steer their planning efforts and provide solid governance for development and implementation of an integrated regional water management plan (IRWMP) in accordance with DWR's Regional Acceptance Process (RAP). The RAP policy is in place to provide pertinent information on the IRWMP region boundaries, make-up, and culture so that DWR can confirm that the region can operate as a region as defined by the California Water Code. 3.6.1 Basefine Per C€al,ita vy`ata:� iJse Per Gatewav Alliance, 2010 t:'ltBAN VV A I l;:lt.

Quantification of volumes received/pumped will be summarized in the following sections. 4.2 ;eater- Sources §10631(b) Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described in subdivision (a): The City of Vernon currently has three sources of water; groundwater, recycled water and imported water. Groundwater is pump from the -Central Basin. Recycled water and imported water are purchased from the Central Basin Municipal Water District (CBMWD).. No additional sources are anticipated to be developed over the planning horizon of this document. Table 6 provides current and projected supplies from these three sources. Projected supply must take into account availability and interim and compliance water use projection per the Gateway Alliance. Table 6 — Current and Projected Water Supplies Iinported Water The City currently purchases treated water from the Central Basin Municipal Water District (CBMWD). According to the 2010 Amendment to Purchase Agreement for Imported Water to Be Provided by Central Basin Municipal Water District (2010 CBMWD Agreement), beginning in 2010 the City had a base allocation of 1,112 AFY of which 90% (1,000 AF) is supplied at the Tier 1 rate. Additional water can be purchased from CBMWD at the Tier 2 rate. While Tier 2 imported water is available in unlimited quantities during normal years, Tier water supply could be reduced in the event of a drought situation or other water shortage. Volumes projected in Table 6 must correspond to volumes that CBMWD intends to provide per their UWMP.

The description and analysis shall be based on information that is.reasonably available, including, but not limited to, historic use records. §10631(b)(4) (Provide a) detailed description and analysis of the amount and location of groundwater that is projected to be pumped by the urban water` supplier. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records. In 2005 the City relied on groundwater for approximately 63% of its potable water supply, and drew its supply from the Central Groundwater Basin. This source annually supplies approximately 200,000 acre feet of potable water to the area south of the Whittier Narrows to .the Pacific Ocean and from the Orange County line to the city of Compton. In 1959, the State Legislature enacted the Water Replenishment Act, enabling the formation of the "Central and West Basin Water_ Replenishment Act" (now referred to as the Water Replenishment District of Southern California or "WRD") to be the permanent agency in charge of replenishing both Basins. The State .Legislature has vested in WRD the statutory responsibility to manage, regulate; replenish and protect the quality of groundwater supplies within it boundaries, of which. the City of Vernon is included. The Central Groundwater Basin became an adjudicated basin in 1966. The Los Angeles County Superior Court oversees the adjudication and the California Department of Water Resources serves as the court appointed'watermaster. The Court established groundwater pumping rights at the time of adjudication, and the total allowable extractions from the basin in. a given year are 217,367 acre feet. Groundwater producers may also carry over up to 20 percent of the allowable pumping rights to the next :fiscal year. Maintenance of the basin and the groundwater pumping allocation requires recharging, accomplished through facilities operated by the Los Angeles County Department of Public Works. The groundwater basin is replenished with three sources of water: import supplies from Metropolitan Water District of Southern California (MWD), local supplies from storm flows and allocations from the Upper San. Gabriel Groundwater Basin, and recycled wastewater from the Los Angeles County Sanitation Districts. 'The Water Replenishment District of Southern California (WRD) purchases import supplies and recycled wastewater 2011} t [LBAta >'4, 1 ii`Cd MAN-'1.GEN'.i1F,N [ PLA:N AwwiniE 22 �f CITY OF VERNON for groundwater replenishment. The District also purchases import supplies to maintain seawater intrusion barriers. Table 4 indicates the historical recharge in the Central Groundwater Basin. The WRD optimizes the use of local and recycled water supplies to replenish the basin. The agency has also taken advantage of surplus water offered at reduced rates from MWD to increase the reliability of this essential supply. Until recently, the WRD offered groundwater producers a program that traded reduced import water supply costs in exchange for setting aside the annual groundwater pumping rights to remain in the ground. The bottom row of Table 4 provides an historical prospective of groundwater recharge that occurred through the in lieu program. The City of Vernon has adjudicated groundwater basin rights of 8,039 acre-feet per year (AFY). For 2005, it is anticipated that the City extracted 7,865 AFY from their wells. For these wells, the average static levels range between 175 to 250 feet; the average pumping levels range from 275 to 350 feet, with an average total depth of 1,480 ft. With additional groundwater leases and carryover from previous years, the actual allowable extraction can exceed 8,039 AFY. As with all retailers in the CBMWD, the City can carryover 20 percent of its unused allocation to the next fiscal year. A recent analysis of the Department of Hraterr Resources Water .Master Records indicate that the potential to lease additional rights within the basin is realistically limited to about 3,500 AFY. During a declared water shortage; the Watermaster (Central Basin) may allow the City to over pump 20 percent of its water rights; however, in doing so it must decrease its allocation by 20 percent the following fiscal year. With this arrangement, the City can sustain itself during a declared water shortage. The City manages its supply so that when additional water is needed, due to the possibility of a shortfall in imported supply, these groundwater rights can be exercised. Table 5 contains the annual historic groundwater production for the City. The nine (9) groundwater production wells extract enough water, in conjunction with imported and recycled water supplies, to meet average and peak demands.

Groundwater Litigation UWMP 4 2.3 Recycled Water. Recycled water is one of the cornerstones of Central Basin's efforts to augment loca`1 supplies and reduce dependence on imported water. Since the planning and construction of Central Basin's recycled water system in the early 1.990's, Central Basin has become a leader in producing and marketing recycled water. This new supply can assist the City of Vernon in meeting the demand for non -potable applications such as commercial and industrial processes. It is only limited by the infrastructure needed to deliver this source to the City of Vernon. „MG 2010 UBAN IA"ATEid. 14A14-fit i ail">li'I l'1,A1� engiRreeringinc 23 4 -CHAPTER FOUR SYSTEM SUPPLIES C1'1W OF VERNON N The City purchased 1,438 AFY of recycled water in 2005 from CBMWD in order to provide service for the on -site cooling towers of a recently constructed power plant (Malburg Generation Station). In order to provide this service, the City of Vernon has constructed almost 10,000 linear feet of recycled water pipeline, capable of supplying recycled water from CBNIWD. The City of Vernon has entered into an agreement with CBMWD to provide recycled water to this powerplant, In the event that the recycled water supply is interrupted, this agreement stipulates that CBM�,VD will increase the supply of Tier 2 imported potable water to compensate for any disruption of recycled water, regardless of the drought conditions in Central Basin. In 2005, the City had identified an additional power plant with on -site cooling towers, anticipated to begin operations within the next five years. Phase I of this power plant, anticipated to be completed prior to 2010, will have an annual recycled water demand of 6,834 AFY. Phase 11, anticipated to be completed by 2015, will require an additional 6,666 AFY of recycled water. An agreement between the City of Vernon and CBMWD is currently being negotiated to provide recycled water to this proposed power plant. Similar to the previous agreement, CBMWD will insure that if the recycled water supply is interrupted, CBMWD will increase the supply of Tier 2 imported water to the City in order to compensate for the disruption of recycled water, regardless of the drought conditions in Central Basin. Furthermore, the City has begun working with CBMWD on the Southeast Water Reliability Project which will provide the necessary infrastructure to provide this additional recycled water through a proposed 42" diameter, looped pipeline. Include information on Vernon's current access to and use of recycled water. .3 11'r nsfer Opportunities §10631(d) Describe the opportunities for exchanges or transfers of water on a short-term or long-term basis. Vernon maintains no interconnections with area agencies except its dedicated imported water supply connection with CBMWD. There are no feasible opportunities to develop water transfers or exchanges acting as an independent water supplier. There may be opportunities to act in cooperation with CBMWD or with the Gateway Alliance; however, there are no such projects being planned at this time and initiation of such projects is expected to occur at the wholesale or JPA level. Cite any reference made by the Gateway :alliance. 4.4 1)esalinaleil Water Opportunities §10631(i) Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply. Vernon is landlocked and has no opportunity to develop desalinated water. Furthermore, the Central Basin is Vernon's only source of groundwater and is also landlocked. CBMWD does not have access to the ocean or any source of brackish water and as such does not anticipate investing in desalination in the near future. 4,5 Recycled Water Opporamities §10633 Provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier's service area. 20it1 i,llllAN WAT. i'Et i .AN.A(.'J Ml.,"N1' PLAN erigme&rtng iate 24 c y �~ •R CHAPTER FOUR - SYSTEM SUPPLIES CITY OF VERNON §10633(a) (Describe) the wastewater collection and treatment systems in the supplier's service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal. §10633(b) (Describe) the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. §10633(c) (Describe) the recycled water currently being used in the supplier's service area, including, but not limited to, the type, place, and quantity of use. §10633(d) (Describe and quantify) the potential uses of recycled water, including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses. §10633(e) (Describe) the projected use of recycled water within the supplier's service area at the end of 5, 10, 15, and 20 years, and a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision. §10633(f) (Describe the) actions, including financial incentives, which may be taken to encourage the use of recycled water, and the projected results of these actions in terms of acre-feet of recycled water used per year. §10633(g) (Provide a) plan for optimizing the use of recycled water in the supplier's service area, including actions to facilitate the installation of dual distribution systems, to promote recirculating .uses, to facilitate the increased use of treated wastewater that meets recycled water standards, and to overcome any obstacles to achieving that increased use: It is the City's philosophy that recycled water shall be used within the jurisdiction wherever its use is economically justified, -financially and technically feasible and consistent with legal requirements, preservation of public health, safety and welfare of the environment. The City will evaluate all proposed water users and will examine implementing mandatory recycled water use for all industrial and commercial users when deemed economically and technically feasible. Although this will not provide a reduction in water rates at this point, thus resulting in a financial incentive, the recycled water will be exempt .from rationing in the event of a drought. 4. A Disposition t fWastelvater Collection and Treatment Per the 2009 Vernon General Plan, the City owns its own sewage collection system which discharges into the system managed by the Los Angeles County Sanitation Districts (LACSD). The majority of Vernon is within District 23, but also contains territory in Districts 1 and 2. These Districts, along with more than a dozen others, are signatories to the Joint Outfall System (JOS) which provides for the operation and maintenance of an interconnected system of wastewater collection, treatment, reuse, and disposal facilities across a large portion of the urban region. The JOS includes the following water reclamation plants (WRP): The Joint Water Pollution Control Plant (Carson) Whittier Narrows WRP (South El Monte) deC 2{ll{l I"1t13.® i',A 1 ['R.MANAG M1'NI� 1'1.

Of that total, 147,703 AFY met Title 22 standards for recycled water and 67,936 AFY (or 46.0%) was reused. 4-5.2 Current Recycled Water Planning The City of Vernon has participated in the Central Basin Water Recycling Master Plan. As both a water agency (purveyor) and groundwater agency, the City has provided input on customer development, rates, facilities and impacts. As mentioned in the "Water Source" section of this report, the City is Currently implementing a recycled water program, and anticipates completion by the year 2010.The City will purchase tertiary water from CB1vIWD. The treated effluent will meet all requirements of Title 22 of the California Code of Regulations. Recycled water is one of the cornerstones of Central Basin's efforts to augment local supplies and reduce dependence on imported water. Since the planning and construction of Central Basin's recycled water system in the early 1990's, Central Basin has become a leader in producing and marketing recycled water. This new supply can assist the City of Vernon in meeting the demand for non -potable applications such as commercial and industrial processes. It is only limited by the infrastructure needed to deliver this source to the City of Vernon: Currently, the City purchases 1,438 AFY of recycled water from CBMWD in order to provide service for the on -site cooling towers of a recently constructed power plant (Malburg Generation Station). In order to provide this service, the City of Vernon has constructed almost 10,000 linear feet of recycled water pipeline, capable of supplying recycled water from CBMWD. The City of Vernon has entered into an agreement with CBMW. D to provide recycled water to this power plant. In the event that the recycled water supply is interrupted, this agreement stipulates that CBMWD will increase the supply of Tier 2 imported potable water to compensate for any disruption of recycled water, regardless of the drought conditions in Central Basin. Recent market assessments, conducted by the City, have identified an additional power plant with on -site cooling towers, anticipated to begin operations within the next five years. Phase I of this power plant, anticipated to be completed prior to 201.0, will have an annual recycled water demand of 6,834 AFY. Phase 1.I, anticipated to be,completed by 201.5, will require an additional 6,666 AFY of recycled water. An agreement between the City of Vernon and CBMWD is currently being negotiated to provide recycled water to this proposed power plant. Similar to the previous agreement, CBMWD will insure that if the recycled water supply is interrupted, CBMWD will increase the supply of Tier 2 imported water to the City in order to compensate for the disruption of recycled water, regardless of the drought conditions in. Central Basin. Furthermore, the City has begun working with CBMWD on. the Southeast Water Reliability Project which will provide the necessary infrastructure to provide this additional recycled water through a proposed 42 diameter, looped Pipeline. In an effort to reduce reliance on imported water and conserve regional groundwater, Central Basin Municipal Water District is moving :forward with the Southeast Water .Reliability Project (SW.RP). SWRP will reduce current regional demand on imported water by 25% by delivering more than 5 billion gallons of recycled water annually to the many large industrial and irrigation sites in the area.

The discrepancy is due to a delay in the expansion of the Malburg Generation Station which was anticipated to dramatically increase to demand for recycled water. The Malburg facility expansion and the construction of an additional power plant in Vernon are anticipated to impact future recycled water demand per the 2009 Vernon General Plan.

An agreement.between the City of Vernon and CBMWD is currently being negotiated to, provide recycled water to this proposed power plant. The City has begun working with CBMWD on the Southeast Water Reliability Project which will provide the necessary intrastructirre to provide this additional recycled water through a proposed 42" diameter, looped pipeline. The City is anticipating purchasing a total of 14,938 AFY of recycled water from CBMWD by 2015. This figure represents the water needs of two power plants, specifically their on. -site cooling towers. Participation for these particular accounts will be mandatory, and optimization is based upon efficient cooling tower operation.

If a drop in efficiency or collective productivity is considered to impact the city's ability to produce an adequate supply of groundwater on a short-term basis as needed, capital improvements are initiated to mitigate the deficiency.

It is not expected that any potable water supply reductions would result in recycled water shortages. In the event of a short-term recycled water shortage, existing and future agreements with CBMWD stipulate that CBVT 1WD will increase the supply of Tier 2 imported potable water to compensate for any disruption of recycled water, regardless of the drought conditions in Central Basin. In the event of a long -teen recycled water shortage, both the existing and proposed power plants, the only current or planned recycled water users, will maintain enough on -site emergency storage to "power down" and terminate operations until the recycled water shortage is over. 2010 t R13AN Vs A1':F :17 M;"rlYtit.l,lllE 1 l"LAN eragi��ceriMginn 34 h CHAPTER FIVE WATER SUPPLY RELUBILITY CITY OF VERNON A Water Quality §10634The plan shall include information, to the extent practicable, relating to the quality of existing sources of water available to the supplier over the same five-year increments as described in subdivision (a) of Section 10631, and the manner in which water quality affects water management strategies and supply reliability. Background information and conclusions in this section are drawn largely from the 2009 Vernon General Plan, the 2009 Vernon Annual Water Quality Report and the 2005 Hydrogeological Evaluation of the City of Vernon Groundwater Supplies prepared by Geosciences Support Services, Inc. A significant portion of water resources in Vernon are drawn from the groundwater basins that underlie the City and surrounding lands. Local groundwater is contained within the Recent, Lakewood, Upper San Pedro and Lower San Pedro aquifers. Because these aquifers extend beneath surrounding jurisdictions, activities both in Vernon and other cities affect the quantity and quality of groundwater. Potential contamination and depletion of the underground basins have been historic concerns, and conditions are continuously monitored to guard against possible interruption of supply. Water quality standards established by federal and State agencies and requirements for water quality monitoring protect end users from contamination and ensure sage drinking water supplies. In particular, National Pollution Discharge Elimination Systems (NPDES) requirements enforced by the State Regional Water Quality Control Board require the control and clean up of surface runoff prior to its discharge into storm drain systems and ultimately into groundwater basins or surface waters. State agencies continue to press for percolation as a means of reclaiming stormwater runoff, both as a mechanism to replenish aquifers and to allow for continued natural cleaning processes. Given Vernon's built -out condition and the severe lack of open space, clean-up and recharge via percolation proves difficult. CBMWD is responsible for ensuring compliance with State and federal drinking water regulations with respect to the water it delivers to Vernon. In addition, CBMWD assists the Central Basin purveyors, including Vernon, to meet drinking water standards with respect to groundwater quality through its Cooperative Basin -Wide Title 22 Groundwater Quality Monitoring Program. Title 22 refers to the California Code of Regulations pertaining to domestic and recycled water standards. Ground water extracted by City wells is of a bicarbonate -type with no dominant cation, but trending toward calcium. In general, the ground eater quality in the aquifers in which the production wells are screened is relative good. The only naturally occurring constituent of concern (COC) throughout the City is manganese. Other localized water quality concerns are: Well No. 14 appears to have problems related to the color of the ground water and high iron content; and Well No: 18 has detections of volatile organic compounds (VOCs) and perchlorate. Mean TDS values within the City wells range from 310 to 530 milligrams per liter (ing/.L). Elevated TDS concentrations (but still below the MCL) occur in the western and eastern portions of the City (see Figure 16). The remainder of the City area has TDS concentrations below 500 mg/L. Higher TDS concentrations are observed .in ground water from shallower aquifers. In general, the majority of the City area has iron concentrations in groundwater below the secondary MCL, of 300 ttg/L (see. Figures 14 and 16). The exception is Well No. 14, which is located in the northwestern portion of the City. Ali other City wells have relatively low iron concentrations, Recent depth -specific sampling in Well No. 18 by WRD (RCS, 2005) indicatedthat iron and manganese concentrations increase with depth (see Table 3). Manganese concentrations in City wells range fi•om below 20 µg/L (detection limit) to 1.06 µg/L (see Figures 15 and 16). In the northern and eastern portions of the City, manganese concentrations exceed the :;C �."..,.�.�....,�.,_..,,._�.-�.,..,...,�,..,....m..�......�..�.�..,,.A.n,.��.. li3tt}URBAN NV,9l [[t.iVlAi"<<A4_.I?ItI1f:N`[' l'1,:1iV er�gi�xeeringinc 35 O CHAPTER FIVE — WATER SU PPLYRELI-ABILITY CITY OF VERNON DHS secondary MCL of 50 µg[L, which is set for aesthetic reasons. A_lthougI :levels remain below the secondary MCL, elevated manganese concentrations occur throughout much. of the remaining areas to the west and south. Other constituents of interest such as arsenic, chromium-6, MTBE, nitrate and nitrite, and NDMA above the MCL are not found in the ground water extracted by the City's wells. No other constituent exceed their respective .MCLs. . As the City of Vernon is predominantly industrial, there are a large number of operational and former facilities that store, use and produce a variety of chemicals that are potential contaminants to the underlying ground water should they be spilt and leak into the ground. Examples of the types of industries within the City are: textile, dry cleaning, trucking terminals, metal fabricating and foundries, machine shops, printing and inks, chemical processing and storage, and food processing. Over 100 potentially contaminating activities have been identified within the City (see Table 4 and Figure 20). Review of site characterization reports for many of the sites undergoing City, Department of Toxic Substances` Control (DTSC) or Los .Angeles Regional Water Quality Control Board (RWQCB) oversight showed contaminants released from potentially contaminating activities (PCAs) generally remain in the soils above the Bellflower aquitard, which occurs from approximately 40 to 80 ft bgs, and in the perched shallow ground water that occurs above the aquitard. Soil contamination was the most frequently reported type of contamination, with some contamination of perched ground water taking place — usually VOC contamination. Regional ground water found at a depth of between 180 ft to 220 ft bgs has rarely reported to been impacted. The source of perchlorate in Well No. 18 remains uncertain. From the facility file review at the City HECD and regulatory databases, no reported spills or leaks of perchlorate are Imown to have occurred. Perchlorate has also not been detected in any of the monitoring wells that have been installed by various potentially responsible parties (PRPs). Perchlorate in other surrounding city water supply wells has also not been detected. Based on ground water production potential, ground water quality, and potential for interference with existing production wells, four ground water production potential zones were delineated for future drilling well sites (see Figure 21). The zones represent relative potential for new well sites, with Zone 1 being the ]Most favorable for new well sites, through Zone 4 which should not.be considered for new well sites. With respect to ground water management options for the City, the following recommendations have been made: Due to the high potential for contamination being introduced into the ground water from the many industries in the City; it is advisable to spread out the location of wells in order to lessen the risk of potential impacts. Wells that will be pumped simultaneously should be spaced at .least 1,300 ft apart to prevent interference between wells; and wells not pumping simultaneously should be spaced at least 800 ft apart. Wells located too close to each other or a well that pumps excessively will cause a localized cone of depression to develop whereby ground water gradients will be altered and ultimately ground water will flow towards these wells (it is important to note that pumping depressions have already formed around Wells 11 and 16, and at Well 20, see Figure 10) The DWSAP assessments for City wells should be used to develop a Drinking Water Source Protection Program and to inform the City's HECD as to the location the capture zones delineated in the assessments. The City should ensure that the industries within these zones are aware that they have the potential to impact the City's water supply. s 20011) URBAN WA1I! R ]MANAGEMENT P] AN „C ciine&riag inc 36 gurrER FIVE - WATER SUPPLY RELIABILITY hgAY AMdS CITY OF VERNON Historical data provided by the City showed evidence of pumping levels being recorded instead of true static levels. In order to obtain static levels, it is recommended that the well pump be turned off for at least six hours prior to a level being recorded. The amount of recovery time allowed before each measurement should also be recorded together with the depth to water. Another recommendation regarding ground water level measurements would be to install permanent pressure transducers in each well. Access into the wells may be a problem in some instances where the pump base does not have port access for sounders. Possibilities to allow a pressure transducer to be installed into the wellsinclude retrofitting the well with a dedicated sounding tube by strapping a PVC tube onto the pump column. To assist in ground water management of the City's ground water resources, a Ground Water Monitoring and Management Plan (GWMMP) is an essential document that incorporates a standard methodology for the collection of data in sufficient quantities and of adequate quality to enable informed decisions regarding the management of the ground water resources in the City's service area. The types of data to be collected include ground water levels, ground water production, and ground water quality. For on -going ground water management, a ground water flow model could be developed for the City area. The model can be used to predict the actual interference effects between wells, evaluate at ground water flow direction changes due to pumping, ground water level changes in response to various operational scenarios and potential movement of contaminants (using particle tracking). The flow model could also be used to predict future ground water conditions for up to 20 years into the future. If treatment is to be considered for treating the iron and manganese problems being experienced in Well no. 14, an oxidation/filtration system is recommended to oxidize and remove the iron and manganese. Chlorine or potassium permanganate is recommended as the chemical to be used for oxidation. Proprietary media or greensand media can be used for filtration. The projected capital cost is estimated to be $1,000,000 and the amortized capital cost is about $80,000. The capital costs include equipment, media, delivery and setup, installation and start-up, instrumentation, engineering, legal, and administration, with a 20 percent contingency. The projected annual O&M costs are estimated to be approximately $72,000. These O&M costs cover oxidant use, media replacement, and electrical costs. Sludge disposal and labor costs are not included in the projection. For treatment of water from Well No. '18, a "tailored" granular activated carbon (TGAQ system or combination of granular activated carbon (GAC) and single -use ion exchange system is recommended for treatment of VOCs (TCE and 1,2-DCA) and perclilorate. The projected capital cost is estimated to be $1.660,000 and the amortized capital cost for both systems is $130,000 based on 20-year amortization and 5 percent interest rate. The capital costs include equipment, media, delivery and setup, installation and start-up instrumentation, engineering, legal, and administration, with a 20 percent contingency. The projected annual O&M costs are estimated to be approximately $200,000. These O&M costs cover oxidant use, media replacement, and electrical costs. Sludge' disposal and labor costs are not included in the projection. Pilot testing may be required for the TGAC system to verify the feasibility for simultaneous removal of and perchlorate and to project a change out time of the media. Depending on the final scope for Well Nos. 14 and 1.8, there could be a number of potential funding sources available to implement the source assessment and treatment of impacted wells. Under certain cases, a project may be co -funded by a combination of multiple funding agencies to finance a project. A number of options have been identified as potential funding sources for the City. These options should be used only as a guide in securing the :fund as the deadline and the eligibility for each program may change without any notice. ¢ „C 2010 URBAN "4'1 A'1'I R NI A:�; NG tilts)' T PLAN er�gtreeritt� inc 37 ar' ' rC1.'1_Y OF VERNON A review of recent work and studies carried out on Well Nos. 14 and 18 have revealed: A The extended suction installed on the pump of Well No. 14 is the cause of the increased iron and color in the ground water pumped by the well, as it now extracts ground water from deeper zones that are known to have elevated iron and manganese concentrations. The perchlorate and VOCs found in Well No. 18 enter the well through the upper portions of the screened interval. Sealing off this portion of the screen will decrease the production capacity of the well. As the sanitary seal depth for Well No. 18 is unknown, but most likely less than 300 ft, it is probably inadequate to exclude. shallow contaminated ground water as is achieved in the other City wells with deeper seals. Due to the advanced age of the wells (older than 43 years) and the infeasibility of treating wells that will need to be replaced within the next 10 years, it is recommended that both these wells be replaced by new wells located in. the Zone 1 or Zone 2 areas depicted on Figure 21. Future wells for the City should be drilled using the reverse circulation rotary drilling method and shall be gravel -packed using current technology for drilling construction, materials, and development. Only water and Baroid Poly -Bore (granular polymer which mixes with water to form borehole stabilization) should be employed as the circulating medium. All boreholes shall be completed in two separate drilling passes. The first pass (pilot borehole) should be made using a 17 1/2-inch diameter bit. Once the drilling, sampling, geophysical borehole logging and aquifer zone testing are completed and the well is to be constructed, the second pass shall enlarge each pilot bore to its final diameter and to the depth specified by the Geohydrologist. The aquifer zone testing must be performed on a minimum of four (4) isolated aquifer zone tests in the pilot borehole. The testing consists of isolating a specific aquifer zone (after drilling the pilot borehole) for testing for both yield and water quality. In order to exclude high TDS ground water and potential contamination, new wells in the City must be constructed with a deep annular seal (approximately 500 ft bgs) and the uppermost screen should start at depths from 600 ft bgs or deeper. The final well design must be based on field observations, geophysical logging and aquifer zone testing results. The type of casing and screen material recommended for new wells is dependent on the ground water quality, expected well rehabilitation. costs, and life expectancy of the wells. A cost benefit analysis carried out for the City of Ontario, based on corrosion testing of coupons, by G.EOSCIENCE (2005), revealed that the long-term cost of stainless steel is cheaper than copper -bearing steel, if rehabilitation/maintenance and replacement costs are taken into account (i.e. on average copper -bearing steel_ wells require to be maintained every 5 years, while stainless steel only requires maintenance every 1.0 years). Two options are available for the well design of new wells for the City. The first option (Option 1) is essentially the same design as Wells No. 19 and 20, which comprises a 500 ft conductor casing cemented in place, 18-inch casing that is telescoped just after 500.ft bgs to 12-inch casing and screen, and installation of gravel. pack from the bottom of the well to the surface. The second option (Option 2) comprises a 50 ft conductor casing cemented into place with 18-inch casingand screen throughout the well, with gravel pack being placed adjacent to the screened portion of the well to 100 ft above the screen, and the remainder of the annulus being filled with cement to form a 500 ft annular seal. Blank wellcasingof either copper -bearing steel or stainless steel must be manufactured using the spiral weld process. The blank well casing should have an inside diameter (ID) of 18 inches and a wall thickness of 5/16 inches. It is recommended that the screened portion of the well be constructed using the same material as the blank casing (i.e. copper -bearing or 304L, stainless steel). The screen should be of the louvered type and be manufactured by Roscoe Moss Company, or an approved equal. The screen must be a horizontal louvered shutter screen (Ful-Flo pattern) with 16 openings per circle, and 192 openings per O 20.101.11 Z13A`r' W A Cis it MAMA(.. ,A4ENT PLAN errgirteerininc 38 Y CHAPTER FIVE - WATER SUPPLY RELIABILITY CITY 01'V1. NO lineal foot. The inside diameter (ID) of the screen should be 18 inches or 12 inches (depending on the well design option), and have a wall thickness of 5/16 inches. The total cost for constructing a 1,600 ft deep, copper -bearing steel cased and screened well, telescoped fi-om 18-inch to 12-inch and with a 500 ft conductor casing (Option 1) is estimated to be $1,616,676 (this includes the well, pump and engineering). The same well constructed with 304L stainless steel is expected to cost approximately $1,958,540. The total cost for constructing a 1,600 ft deep, l 8-inch copper -bearing steel cased and screened well with a 50 ft conductor casing and 500 ft annular seal (Option 2) is estimated to be $1,474,976 (this includes the well, pump and engineering). The same well constructed with 304L stainless steel is expected to cost approximately $1,901,840. The well design recommended is Option 1. although this well design is more expensive than other commonly used designs, it provides greater protection against shallow contamination. Due to the nature of the landuse in the City (i.e. highly industrialized), this extra protection is worth the additional expense.

The City of Vernon adopted Ordinance No. 995 in 1991, which enacted Article VI of Chapter 25 of the Code of the City of Vernon, `'Water Conservation", containing Code Sections 25.100 through 25.1.11. Minimum requirements were outlined in this Ordinance to protect the water supplies and to establish standards :for reductions in the use of water in the City of Vernon. The City's "Water Conservation" code was further amended in 2006 through the adoption of City Ordinance No. 11.15. Continuing the City's proactive approach to water conservation, the City recently adopted Ordinance No. 1 161. (Appendix C) in October 2009, which further expanded the City's water conservation efforts by amending Article VI of Chapter 25 of the Code of the City of Vernon. This Ordinance established general water waste provisions, as well as conservation measures for Phase 1, Phase .11. and Phase III watershortages. These shortages equate to water supply deficiencies of 20%, 30% and 50% and greater, respectively. The City has developed a three stage rationing plan to invoke during declared water shortages, in addition to specific water waste provisions mandated regardless of supply conditions. The rationing plan includes mandatory rationing in order to obtain the associated customer reduction goal 5.5� 1 RatiMung Stages During declared shortages, or when a shortage declaration appears imminent, Ordinance No. 1161. establishes_ conservation measures for Phase I., Phase 11 and Phase III water shortages. These shortages equate to water supply deficiencies of 20%, 30% and 50% or greater, respectively. Restrictions are outlined governing acceptable water use for commercial, industrial, institutional and residential customers dining declared water shortages. Penalties for violations include increase water surcharges, as well as the installation of flow restriction devices. Customers may file applications for relief from these provisions with the Director of Community Services of the City of Vernon. 5.5.2 Man(Lit.hry Prohibitions A .Phase 1 water supply shortage may be declared when the City Council determines it is likely that the City of Vernon will suffer a shortage in City water supplies up to 20%, but shall become mandatory when the City Council determines that the City will suffer a water shortage in excess of 26% of its normal water supplies.

In the City of Vernon, residential water use accounts for less than 0.1 % of total water consumption (Table 7). As such, the City has 4 relatively small amount of residential users requiring a high efficiency washing machine rebate program. 6.2. 7 DMM 7 — Public .Infor niartion Programs The City continues to operate a strong outreach program, as it has for the past several decades. Public information about the City of Vernon and its mission, programs and events are constantly disseminated to many interested parties in order to promote water conservation. The City provides information for customers at the front desk of the Department of Community Services, and maintains a strong link with the local news media through press releases on important subjects to reinforce the conservation message. The City uses numerous printed materials to send information to the community. The Vernon Gazette is a community newsletter, which is delivered monthly to every address in the City's service area. The publication includes articles on water quality, conservation and infrastructure improvement information. In addition, the Department of Community Services publishes an annual water quality report, which.provides quality information, and promotes water conservation. The Water Quality Report is delivered to every service address in the City's service area. Both publications are also available for download on the City's website at www.cityofvernon.org. _4<8 tti'IM 8,- Selwal Education Programs The City of Vernon is almost entirely industrial and commercial, with a very small residential population that was estimated to be 94 people in 2005. The City has only one (1) school within its service area, which is the Vernon Elementary School. The City of Vernon's Public Works and Water Superintendent has given presentations at the School previously, which highlight efficient use of resources and water conservation. The City anticipates expanding their school education program with Vernon .Elementary School, and intends to create a poster contest to promote water conservation with the school children. Although still preliminary, the program is anticipated to consist of providing each age appropriate class with poster.paper and a water conservation related giveaway. The winning posters in three age categories may be displayed in the Department of Community Services. The students will also receive information on water supply and simple water conservation tips, which meet state educational requirements. The City will track the number of classes which participate to track the effectiveness of the School Education Program, 6.2.9 DMM 9 --- Ceiaeserviit°aran Progr°a in for ('11 Accounts The construction of new development is limited in the City of Vernon, due to the availability of vacant or underutilized land in the service area, but all new Commercial, Industrial and institutional building plans must be submitted to the City's Building Section :for review and approval. Water saving appurtenances and fixtures are a requirement of the approval process and are required to obtain a permit. A water consumption review is performed and based upon the Building Section's estimated water use, an appropriate size water meter is selected in order to ensure that all consumption is billed by volume, which in turn, provides a financial incentive to encourage water conservation. As a member agency of the Central Basin Municipal Water District (CBMWD), the City also utilizes CBMWD's conservation programs to promote CH conservation. CBMWD participates in. M.

To date the City has not developed or implemented a residential water use survey, although the majority of the single-family residences within the City have been retrofitted with ultra -low flow toilets. As a primarily commercial/industrial City, water use for residential landscaping is kept at a minimum. 62.2 MM•a:.2 -- Residenthd 'Plumbing Retrofit The City of Vernon's customer base primarily consists of Industrial and Commercial customers. In the City of Vernon, residential water use accounts for less than 0.1 % of total water consumption (Table 7). As such, the City has a relatively small amount of residential users requiring plumbing retrofits beyond those provided for in DNIM14 (ULFT). 6.2.1 11@ A4 2—Water Audits, Leak Detection and Repair According to the California Urban Water Conservation Council (CUWCC), water system audits quantify water production and water sales, testing water meters, and field checking the distribution system. The City does not contract for a distribution leak audit. As presented in Table 7, the City's unaccounted for water loss in 2000 and 2005 is approximately 5%, a significant decrease from the approximately 11% water loss recorded in 1995. The cost of an audit is approximately $100,000. With water loss at 5%, it is unlikely that -a leak detection audit would save more than 10% of the unaccounted for water in the distribution system, as 5% system- wide loss is lower than typical industry losses. This equates to a potential savings of 57 AFY of unaccounted water loss, based on the 2005 water .loss reported in Table 7. The cost of an acre foot of water in Fiscal Year 2004-05 was $457 (Tier I purchase rate from CBWD). As such, the water audit represents an annual potential savings of approximately $26,049, or a potential three-year savings of $78,147. As this is less than the estimated $1.00,000 cost, a system water audit is not cost effective at this time. 6.2.4 D[x'iM 4 ieterilig with Commodity Rates All existing and new City service connections are metered in order to ensure that consumption is metered by volume. As the City is primarily industrial and commercial and has a relatively low number of residential connections, dedicated landscape meters are not feasible. The City began metering water accounts in 1925. As presented in Table 8, there were 1,200 metered service connections in 2005. As presented in Table 7, the City's unaccounted for water loss in 2000 and 2005 is approximately 5%, indicating that the City's service meters are operating properly. Accordingly, 95% of all water produced or purchased by the City is billed by metered consumption. Each user is charged a basic meter charge for service and a quantitative charge for water used. In 2005, all consumption was billed at a rate of $1.027 per HCF. The City will continue to install and read meters on all new services, and will continue to conduct its meter calibration and replacement program. Immediate attention is given to any metered amount which reflects an unexpected variance.

This Ordinance established general waste water provisions, as well as conservation measures for Phase I, Phase 11 and Phase Ili water shortages. The waste water provisions apply regardless of supply conditions, and include: Limits on Watering Hours: Watering or irrigating of lawn, landscape or other vegetated area with potable water is prohibited between the hours of 10:00 a.m. and 5:00 p.m. on any day, except by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive selfclosing water shut-off nozzle or device, or for very short periods of time for the express purpose of adjusting or repairing an irrigation system. Limit on Watering Duration: Watering or irrigating of lawn, landscape or other vegetated area with potable water using a landscape irrigation system or a watering device that is not continuously attended is limited to no more than fifteen (15) minutes watering per day per station. This subsection does not apply to landscape irrigation systems that exclusively use very low -flow drip type irrigation systems when no emitter produces more than two (2) gallons of water per hour and weather based controllers or stream rotor sprinklers that meet a seventy percent (70%) efficiency standard. No Excessive Water Flow or Runoff: Watering or irrigating of any lawn, landscape or other vegetated area in a manner that causes or allows excessive water flow or runoff onto an adjoining sidewalk, driveway, street, alley, gutter or ditch is prohibited. No Washing Down Hard or Paved Surfaces: Washing down hard or exterior paved surfaces, including but not limited to sidewalks, walkways, driveways, parking areas, patios or alleys, is prohibited except when necessary to alleviate safety or sanitary hazards, and then only by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self -closing water shut-off device, a low -volume, high-pressure cleaning machine equipped to recycle any water used, or a low -volume high-pressure water broom. Obligation to Fix Leaks, Breaks or. Malfunctions: Excessive use, loss or escape of water through breaks, leaks or other malfunctions in the water user's plumbing or distribution system for any period of time after such escape of water should have reasonably been discovered is prohibited and shall be repaired as soon as reasonably practicable. Re -circulating Water Required for Water Fountains and Decorative Water Features: Operating a water fountain or other decorative water feature that -does not use re -circulated water is prohibited. Limits on Washing Vehicles: Using water to wash or clean a vehicle, including but not limited to any automobile, truck, van, bus, motorcycle, boat or trailer, whether motorized or not is prohibited, except by use of a hand-held bucket or similar container or a hand-held hose equipped with a positive self -closing water shut-off nozzle or device. This subsection does not apply to any commercial vehicle washing facility. 20.10 �' .'-�N WATER ER INIA �'.AGI.,fd.1�.t4 1' ��1...:�.N ric�t�e 48 y,4 t ��st�3¢4Y SAS$. � ,... w...�,..�,.. ,...-............,.-.,m....».............�.....,......�.t.�.�.,-rs..W.....,,.,,.A......«,..

In 2002, the California Urban Water Conservation Council (CUWCC) pursued and received a $2.3 million grant from the California Public Utilities Commission (CPUC) to purchase and install restaurant pre -rinse spray nozzle valves. The new nozzles use 1.6 gpm compared to 2 to 6 gpm valves. These valves conserve water, heating costs, and reduce waste -water discharge. CBMWD supported CUWCC's efforts in marketing the program. The nozzles and installations were provided fi•ee of charge to several food services customers in the City's service area. In 2003, CBMWD applied for and received a $780,000 Proposition 13 grant for the purchase and installation of 2,600 Waterless Urinals. Waterless urinals can save an average of 40,000 gallons of water per year. CBMWD is has installed four (4) of these devices within the City's service area, including installation at City Hall_ 0.2.1.0 IVIFNl 10 - Wlifilesale Ag<ncy Pr•ogi—rants As a part of its "Shut Your Tap!" Conservation Campaign, CBMWD hosts a bi-monthly event called the "Shut Your Tap! Roundtable". The Roundtable provides a forum for cities, water agencies and interested parties to ,share ideas and information on conservation trends and issues. The setting provides for interaction and networking among area water stakeholders. In order to provide member cities with support for their marketing, outreach and enforcement of local mandatory water conservation ordinances, a "Water Use Efficiency Ordinance Tool Kit" was developed by CBMWD.

The City began conservation pricing in 1925. As presented in Table 8, there were 1.,200 metered service connections in 2005. As presented in Table 7, the City's unaccounted for water loss in 2000 and 2005 is approximately 5%, indicating that the City's service meters are operating properly. Accordingly, 95% of all water produced or pi-rchased by the City is billed by metered consumption. Each user is charged a basic charge for service and a quantitative charge for water used. In 2005, all consumption was billed at a rate of $1.027 per HCF. During rationing, 6 :HCF of water allotment is the minimum amount that each customer will be supplied, due to health and safety considerations. During periods of extreme water supply shortages, the City may need to raise water rates. This will be handled on a case -by -case basis. Sewer service is provided by the Sanitation Districts of L,os Angeles County and sewer charges are the responsibility of the Sanitation Districts. 6132 .
