AGENDA STAFF REPORT DATE: June 13, 2011 TO: Honorable Mayor and City Council THRU: Jill R. Ingram, Acting City Manager FROM: Sean P. Crumby P.E., Director of Public Works SUBJECT: CONDUCT PUBLIC HEARING FOR URBAN WATER MANAGEMENT PLAN AND SET DATE FOR ADOPTION SUMMARY OF REQUEST: It is requested that the City Council hold a public hearing and set the date for June 27, 2011 to adopt the 2010 Update to the Urban Water Management Plan. BACKGROUND AND ANALYSIS: The California Water Code 10644 (a) requires water suppliers (including wholesalers), either publicly or privately owned, that provide water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre -feet annually to submit an updated Urban Water Management Plan (UWMP) with the Department of Water Resources at least once every five years; in years ending in five or zero. This year the UWMPs are not due until July 1, 2011 (six months later) due to the recent adoption of SBx7 -7 - 20% by 2020 conservation requirement. The UWMP describes the service area, including the demographic factors, water sources, reliability planning, water use provisions, supply and demand comparison provisions, and water demand management measures. Accordingly, the City of Seal Beach prepared its first Urban Water Management Plan in 2000. This plan was adopted by the City Council on May 29, 2001. The Plan included as water demand management measures the sixteen Best Management Practices (BMP's) adopted by California Urban Water Conservation Council (CUWCC) that were also approved by the Council at the time of authorization of the Orange County Sanitation District Cooperative Projects contracts. The Urban Water Management Plan was updated and adopted by the City Council again in 2002 and 2005. These two successive updates have met the required schedule and incorporated legislative updates from the State. Agenda Item S Page 2 It is again time to update the UWMP for water suppliers. The Municipal Water District of Orange County (MWDOC) has taken a leadership role with preparation of this update for all of the agencies that are included within their region. It is an appropriate action for MWDOC to undertake some of the items incorporated into the UWMP, MWDOC solicited bids from qualified consultants to prepare the UWMP for all the agencies (Cities and Water Districts). The theory being that the cost to prepare a larger amount of UWMP's will be cheaper for each agency. At the August 9, 2010 City Council Meeting, Council awarded a professional contract with Malcolm Pirnie for $29,222 to prepare the 2010 UWMP. Staff has reviewed the document and has approved it. The document has met all Federal and State regulations. FINANCIAL IMPACT: There is no financial impact. RECOMMENDATION: It is recommended the City Council set a public hearing date for June 27, 2011 to adopt the 2010 Update to the Urban Water Management Plan.

The UWMP has been prepared consistent with the requirements under Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act (Act), which were added by Statute 1983, Chapter 1009, and became effective on January 1, 1984. The Act requires "every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre -feet of water annually" to prepare, adopt, and file an UWMP with the California Department of Water Resources (DWR) every five years. 2010 UWMP updates are due to DWR by August 1, 2011. Since its passage in 1983, several amendments have been added to the Act. The most recent changes affecting the 2010 UWMP include Senate Bill 7 as part of the Seventh Extraordinary Session (SBx7 -7) and SB 1087. Water Conservation Act of 2009 or SBx7- 7 enacted in 2009 is the water conservation component of the Delta package. It stemmed from the Governor's goal to achieve a 20% statewide reduction in per capita water use by 2020 (20x2020). SBx7 -7 requires each urban retail water supplier to develop urban water use targets to help meet the 20% goal by 2020 and an interim 10% goal by 2015. Service Area and Facilities The City provides water to a population of 25,561 throughout its service area. The City receives its water from two main sources, the Lower Santa Ana River Groundwater basin, which is managed by the Orange County Water District (OCWD) and imported water from the Municipal Water District of Orange County (MWDOC). Groundwater is pumped from 3 active wells located throughout the City, and imported water is treated at the Diemer Filtration Plant and is delivered to the City through one imported water connections. Water Demand Currently, the total water demand for retail customers served by the City is approximately 4,600 acre -feet annually consisting of 1,750 acre -feet of imported water and 2,850 acre - feet of local groundwater. With its diligence in the promotion of water conservation as well as financial incentives to customers to retrofit their homes and businesses with water efficient devices and appliances, the City is projecting a 6% demand increase in the next 25 years accompanying a projected 7% population growth. With MWDOC's assistance, the City has selected to comply with Option 3 of the SBx7 - 7 compliance options. The City is a member of the Orange County 20x2020 Regional •_A City of Seal Beach � IRNIE ALCM 2010 Urban Water Management Plan 1 ,�= Executive Summary Alliance formed by MWDOC. This regional alliance consists of 29 retail agencies in Orange County. Since the minimum required target applies, the City's 2015 interim water use target is 145.6 GPCD and the 2020 final water use target is 139.5 GPCD. Water Sources and Supply Reliability The City's main sources of water supply are groundwater from the Lower Santa Ana River Groundwater Basin and imported water from Metropolitan through MWDOC. Today, the City relies on 62% groundwater-and 38% imported. It is projected that through 2035, the water supply mix will remain roughly the same. The sources of imported water supplies include the Colorado River and the State Water Project (SWP). Metropolitan's 2010 Integrated Water Resources Plan (IRP) update describes the core water resource strategy that will be used to meet full - service demands (non - interruptible agricultural and replenishment supplies) at the retail level under all foreseeable hydrologic conditions from 2015 through 2035. It is required that every urban water supplier assess the reliability to provide water service to its customers under normal, dry, and multiple dry water years. Metropolitan's 2010 RUWMP finds that Metropolitan is able to meet full service demands of its member agencies with existing supplies from 2015 through 2035 during normal years, single dry year, and multiple dry years. The City is therefore capable of meeting the water demands of its customers in normal, single dry, and multiple dry years between 2015 and 2035, as illustrated in Table 3 -12, Table 3 -13, and Table 3 -14, respectively. Future Water Supply Projects In Orange County, there are three proposed ocean desalination projects that could serve MWDOC, including one specifically that may benefit the City. On May 24, 2010, the City signed a non - binding LOI for 0.8 MGD (850 AFY) of Huntington Beach Seawater Desalination Project supplies. 5 1,4''' l o City of Seal Beach IRNI 2010 Urban Water Management Plan 2 1. Introduction 1.1. Urban Water Management Plan Requirements Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act (Act) require "every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre -feet of water annually" to prepare, adopt, and file an UWMP with the California Department of Water Resources (DWR) every five years. 2010 UWMP updates are due to DWR by August 1, 2011. This UWMP provides DWR with information on the present and future water resources and demands and provides an assessment of the City's water resource needs. Specifically, this document will provide water supply planning for a 25 -year planning period in 5 -year increments. The plan will also identify water supplies for existing and future demands, quantify water demands during normal year, single -dry year, and multiple -dry years, and identify supply reliability under the three hydrologic conditions. The City's 2010 UWMP update revises the 2005 UWMP. This document has been prepared in compliance with the requirements of the Act as amended in 2009, and includes the following analysis: O Water Service Area and Facilities • 0 Water Sources and Supplies O Water Use by Customer Type O Demand Management Measures O Water Supply Reliability O Planned Water Supply Projects and Programs O Water Shortage Contingency Plan O Recycled Water Since its passage in 1983, several amendments have been added to the Act. The most recent changes affecting the 2010 UWMP include Senate Bill 7 as part of the Seventh Extraordinary Session (SBx7 -7) and SB 1087. Water Conservation Act of 2009 or SBx7- 7 enacted in 2009 is the water conservation component of the historic Delta package. It stemmed from the Governor's goal to achieve a 20% statewide reduction in per capita water use by 2020 (20x2020). SBx7 -7 requires each urban retail water supplier to develop urban water use targets to help meet the 20% goal by 2020 and the interim 10% goal by 2015. Each urban retail water supplier must include in its 2010 UWMPs the following information from its target- setting process: City of Seal Beach v,tviALCOLM ': 2010 Urban Water Management Plan 1 -1 PIRNI Section 1 Introduction O Baseline daily per capita water use a 2020 Urban water use target o 2015 Interim water use target o Compliance method being used along with calculation method and support data Wholesale water suppliers are required to include an assessment of present and proposed future measures, programs, and policies that would help achieve the 20 by 2020 goal. The other recent amendment made to the UWMP Act to be included in the 2010 UWMP is set forth by SB 1087, Water and Sewer Service Priority for Housing Affordable to Low - Income Households. SB 1087 requires water and sewer providers to grant priority for service allocations to proposed developments that include low income housing. SB 1087 also requires UWMPs to include projected water use for single- and multi - family housing needed for low- income households. The sections in this UWMP correspond to the outline of the Act, specifically Article 2, Contents of Plans, Sections 10631, 10632, and 10633. The sequence used for the required information, however, differs slightly in order to present information in a manner reflecting the unique characteristics of the City's water utility. The UWMP Checklist has been completed, which identifies the location of Act requirements in this Plan and is included as Appendix A. • II '4 OL�1 City of Seal Beach Y IRNIE 2010 Urban Water Management Plan 1 - Section 1 Introduction :J — •-- r- -! - - -- .� &marina La Habra 7 i . • Brc'a , _1 \ _un% •,- ti . t I • J �_ ,, ,. f- �I(p ) [ Linda Water District +` + Fullerton �.

City of Seal Beach 1:AtALCOLN1 _r 2010 Urban Water Management Plan 1 -8 2. Water Demand 2.1. Overview Currently, the total water demand for retail customers served by the City is approximately 4,600 acre -feet annually consisting of 1,750 acre -feet of imported water and 2,850 acre - feet of local groundwater. With its diligence in the promotion of water conservation as well as financial incentives to customers to retrofit their homes and businesses with water efficient devices and appliances, the City is projecting a 6% demand increase in the next 25 years accompanying a projected 7% population growth. The passage of SBx7 -7 will increase efforts to reduce the use of potable supplies in the future. This new law requires all of California's retail urban water suppliers serving more than 3,000 AFY or 3,000 service connections to achieve a 20% reduction in potable water demands (from a historical baseline) by 2020. Due to great water conservation efforts in the past decade, the City is on its way to meeting this requirement on its own. Moreover, the City has elected to join the Orange County 20x2020 Regional Alliance. The City together with other 28 retail agencies in Orange County are committed to reduce the region's water demand by 2020 through the leadership of MWDOC, the region's wholesale provider. This section will explore in detail the City's current water demands by customer type and the factors which influence those demands as well as providing a perspective of its expected future water demands for the next 25 years. In addition, to satisfy SBx7 -7 requirements, this section will provide details of the City's SBx7 -7 compliance method selection, baseline water use calculation, and its 2015 and 2020 water use targets. 2.2. Factors Affecting Demand Water consumption is influenced by many factors from climate characteristics of that hydrologic region, to demographics, land use characteristics, and economics. The key factors affecting water demand in the City's service area are discussed below. 2.2.1. Climate Characteristics The City is located in an area known as the South Coast Air Basin (SCAB). The SCAB climate is characterized by southern California's "Mediterranean" climate: a semi -arid environment with mild winters, warm summers and moderate rainfall. The general region lies in the semi - permanent, high pressure zone of the eastern Pacific. As a result, the climate is mild, tempered by cool sea breezes. The usually mild climatologically pattern ° City of Seal Beach A ALCOIAt ', . IRN I 2010 Urban Water Management Plan 2 - Section 2 Water Demand is interrupted infrequently by periods of extremely hot weather, winter storms, or Santa Ana winds. The City's average temperature ranges from 56 degrees Fahrenheit in January to 69 degrees Fahrenheit in August with an average annual temperature of 62 degrees Fahrenheit. Annual precipitation is typically approximately 12 inches, occurring mostly between November and March (Table 2 -1). The average evapotranspiration (ETo) is almost 50 inches per year, which is four times the annual average rainfall. This translates to a high demand for landscape irrigation for homes, commercial properties, parks, and golf courses. A region with low rainfall like Southern California is also more prone to droughts. Table 2 -1: Climate Characteristics Standard I . ' ' r Average • • j 'Annual R ainfall - • • - • . .

Demographics Since its incorporation in 1915, the City has grown from a population of 250 to over 25,000. The City's total population in 2010 was 25,561 according to Center for Demographic Research (CDR) at California State University Fullerton. CDR projects a 7% increase in the City's population over the next 25 years to 27,242 by 2035. This represents the City's expected ultimate population which will occur through infill and densification. The modest increase in population seen in Table 2 -2 is due to the residential development of the Hellman Ranch area, planned development of the Department of Water and Power property, and the increase in net allowable densities in already developed areas at ultimate build -out.

Land Use The City is almost built out and is a predominantly residential community located along the California coastline in Orange County. Future increases in demand will result from two approved development projects that are under construction (Hellman Ranch and Pacific Gateway, also known as the Boeing Facility), one future development area (former Department of Water and Power Property), and infill development. Hellman Ranch Project — It covers 199 acres, and is located west of Seal Beach Boulevard, north of Marina Hill. The development will include 100 acres of open space, freshwater wetlands and 70 single - family residential units. Pacific Gateway Project — The Pacific Gateway project is located west of Seal Beach Boulevard between Adolfo Lopez Drive and Westminster Avenue. It is a part of the 107 acre Boeing Space and Communications Campus. It will have development on three of the four planning areas on site. Planning Area 1 is developed and covers 41 acres. The remaining planning areas will include 31 acres of industrial, 19 acres of commercial, and a 120 room hotel on 2 acres. A firm development plan does not currently exist for the former Department of Water and Power facility. The future demands have been estimated based upon the general plan allowed density for single family residential development. fn City of Seal Beach MALCOL 1 2010 Urban Water Management Plan 2 - Section 2 Water Demand 2.3. Water Use by Customer Type The knowledge of an agency's water consumption by type of use or by customer class is key to developing that agency's water use profile which identifies when, where, how, and how much water is used, and by whom within the agency's service area. A comprehensive water use profile is critical to the assessment of impacts of prior conservation efforts as well as to the development of future conservation programs. This section provides an overview of the City's water consumption by customer type in 2005 and 2010, as well as projections for 2015 to 2035. The customer classes are categorizes as follows: single - family residential, multi - family residential, commercial/industrial /institutional (CII), dedicated landscape, and agriculture. Other water uses including sales to other agencies and non - revenue water are also discussed in this section. 2.3.1. Overview The City has approximately 5,179 customer connections to its potable water distribution system. No new connections are expected to come on -line. The City is projecting a 6% demand increase by 2020. After that demand is expected to remain stable. Approximately 44% of the City's water demand is residential. CII including dedicated landscape consume approximately 56% of the City's water supply. The City does not provide water for agricultural uses. Tables 2 -3 and 2 -4 provide a summary of the past, current, and projected number of water service customers and water use by customer class in five -year increments from 2005 through to 2035. ,`X City of Seal Beach ALCOt�1x 2010 Urban Water Management Plan 2 - 4 IRNI Section 2 Water Demand Table 2 -3: Past, Current and Projected Service Accounts by Water Use Sector • F . ,'. -, Number of,Accourits.by Water U'se +; . <...: �Ericli ri, • � � � � • .. .rl' : •• ::- : - ' � • • ^- .;: � :, ; .

Residential Residential water use accounts for approximately 44% of the City's water demands. The remaining demands are for the non - residential sector and system losses. Water consumption by the residential sector is projected to remain at about 44% through the 25- year planning horizon. 2.3.3. Non - Residential In 2010 non - residential demand was approximately 56% of the overall demand and is expected to remain so through 2035. The City has a mix of commercial customers, ranging from markets, restaurants, small stores, offices, beauty shops, and gas stations to multi -story office buildings and restaurants and other facilities serving the visitor population. The City has no industrial sector other than some light aerospace manufacturing. The industrial sector has decreased much in the last decade. However, the Pacific Gateway development will add to this sector. The City has a stable { $ City of Seal Beach M ALCO r 2010 Urban Water Management Plan 2 - PIR Section 2 Water Demand institutional /governmental sector, primarily local government, schools, visitor serving public facilities, and a much - scaled down Naval Base. Demands from CII are expected to remain at around 56% of the City's total water demands for the next 25 years. 2.3.4. Other Water Uses 2.3.4.1. Sales to Other Agencies The City does not sell water to other agencies. 2.3.4.2. Non - Revenue Water Non - revenue water is defined by the International Water Association (IWA) as the difference between distribution systems input volume (i.e. production) and billed authorized consumption. Non - revenue water consists of three components: unbilled authorized consumption (e.g. hydrant flushing, fire fighting, and blow -off water from well start-ups), real losses (e.g. leakage in mains and service lines), and apparent losses (unauthorized consumption and metering inaccuracies). The City's non - revenue water accounts for approximately 8% of the City's total water use and is expected to remain so (Table 2 -5).

SBx7 -7 Requirements 2.4.1. Overview SBx7 -7, which became effective on February 3, 2010, is the water conservation component to the Delta legislative package. It seeks to implement Governor Schwarzenegger's 2008 water use reduction goals to achieve a 20% statewide reduction in urban per capita water use by December 31, 2020. As discussed above, the bill requires each urban retail water supplier to develop urban water use targets to help meet the 20% City of Seal Beach NALCCILILI.4. 2010 Urban Water Management Plan 2 - _ Section 2 Water Demand goal by 2020 and an interim 10% goal by 2015. The bill establishes methods for urban retail water suppliers to determine targets to help achieve water reduction targets. The retail water supplier must select one of the four compliance options. The retail agency may choose to comply to SBx7 -7 as an individual or as a region in collaboration with other water suppliers. Under the regional compliance option, the retail water supplier still has to report the water use target for its individual service area. The bill also includes reporting requirements in the 2010, 2015, and 2020 UWMPs. An agency that does not comply with SBx7 -7 requirement will not be eligible for water related grant, or loan, from the state on and after July 16, 2016. However, if an agency that is not in compliance documents a plan and obtains funding approval to come into compliance then could become eligible for grants or loans. 2.4.2. SBx7 -7 Compliance Options DWR has established four compliance options for urban retail water suppliers to choose from. Each supplier is required to adopt one of the four options to comply with SBx7 -7 requirements. The four options include: o Option 1 requires a simple 20% reduction from the baseline by 2020 and 10 percent by 2015. o Option 2 employs a budget -based approach by requiring an agency to achieve a performance standard based on three metrics o Residential indoor water use of 55 GPCD o Landscape water use commiserate with Model Landscape Ordinance o 10 percent reduction in baseline CII water use 3 Option 3 is to achieve 95% of the applicable state hydrologic region target as set forth in the State's 20x2020 Water Conservation Plan. o Option 4 requires the subtraction of Total Savings from the Base GPCD: o Total Savings includes indoor residential savings, meter savings, CII savings, and landscape and water loss savings. Seal Beach's Compliance Option Selection With MWDOC's assistance in the calculation of the City's base daily per capita use and water use targets, the City has selected to comply with Option 3. While each retail agency is required to choose a compliance option in 2010, DWR allows for the agency to change its compliance option in 2015. This will allow the City to determine its water use targets for Compliance Option 2 and 4 as it anticipates more data to be available for targets calculation in the future. City of Seal Beach tvtALCOlyl .1 IRNI 2010 Urban Water Management Plan 2 - • Section 2 Water Demand 2.4.3. Regional Alliance Retail agencies can choose to meet the SBx7 -7 targets on its own or several retail agencies may form a regional alliance and meet the water use targets as a region. The benefit for an agency that joins a regional alliance is that it has multiple means of meeting compliance. The City is a member of the Orange County 20x2020 Regional Alliance formed by MWDOC. This regional alliance consists of 29 retail agencies in Orange County as described in MWDOC's 2010 RUWMP. The Regional Alliance Weighted 2015 target is 174 GPCD and 2020 target is 157 GPCD. 2.4.4. Baseline Water Use The first step to calculating an agency's water use targets is to determine its base daily per capita water use (baseline water use). This baseline water use is essentially the agency's gross water use divided by its service area population, reported in gallons per capita per day (GPCD). The baseline water use is calculated as a continuous 10 -year average during a period, which ends no earlier than December 31, 2004 and no later than December 31, 2010. Agencies that recycled water made up 10% or more of 2008 retail water delivery can use up to a 15 -year average for the calculation. Recycled water use represents less than 10% of the City's retail delivery in 2008; therefore, a 10 -year instead of a 15 -year rolling average was calculated. The City's baseline water use is 151.7 GPCD, which was obtained from the 10 -year period Julyl, 1995 to June 30, 2005. Tables 2 -6 and 2 -7 provide the base period ranges used to calculate the baseline water use for the City as well as the service area population and annual water use data which the base daily per capita water use was derived. Data provided in Table 2 -6 was used to calculate the continuous 10 -year average baseline GPCD. Moreover, regardless of the compliance method adopted by the City, it will need to meet the minimum water use target of 5% reduction from a five -year baseline as calculated in Table 2 -7. Because the City is an OCWD agency, the City's gross water use includes deductions for indirect potable recycled water use from the Groundwater Replenishment System (GWRS) and Water Factory 21 managed by OCWD. The calculations for the gross water use are described in MWDOC's 2010 RUWMP. 4 City of Seal Beach x1 .

Water Use Reduction Plan The City is a member agency of MWDOC and a member of the Orange County 20x2020 Regional Alliance comprising 29 retail urban water suppliers in Orange County. The Orange County 20x2020 Regional Alliance was created to allow local water suppliers to meet their 20% by 2020 reduction targets under SBx7 -7 on a regional basis through the successful implementation of region -wide programs. The Orange County 20x2020 Regional Alliance will achieve its water use reduction by building on the existing collaboration between Metropolitan, MWDOC and the local agencies in Orange County. MWDOC as a regional wholesale water provider implements many of the urban water conservation Best Management Practices (BMPs) on behalf its member agencies. MWDOC's conservation measures are detailed in MWDOC's RUWMP Section 4, and Metropolitan's conservation measures detailed in Metropolitan's 2010 RUWMP Section 3.4. Additionally, Metropolitan in collaboration with MWDOC and other Metropolitan member agencies is in the process of developing a Long Term Conservation Plan,' which seeks an aggressive water use efficiency target in order to achieve a 20% reduction in per capita water use by 2020 for the entire Metropolitan service area. Metropolitan Long Term Conservation Plan Metropolitan's Long Tenn Conservation Plan will build on Metropolitan's traditional programs of incentives, education and broad outreach while developing a new vision of water use efficiency by altering the public's perspective on water through market transformation. The overreaching goals of the Long Term Conservation Plan are as follows: o Achieve the 2010 IRP conservation target — The target for new water savings through conservation is a regional per capita use of 159 gallons per day in 2015 and 141 gallons per day in 2020. o Pursue innovation that will advance water conservation ! Metropolitan Water District of Southern California Long Term Conservation Plan Working Draft Version 6 (November 30, 2010) ' z' ' IV IRN City of Seal Beach AL GOL 2010 Urban Water Management Plan 2 - IE Section 2 Water Demand • Transform the public's value of water within this region — A higher value on water within this region can lead to a conservation ethic that results in permanent change in water use behavior, earlier adoption of new water saving technologies, and transition towards climate- appropriate landscapes. Achieving these goals requires the use of integrated strategies that leverage the opportunities within this region. It requires regional collaboration and sustained support for a comprehensive, multi -year program. It requires a commitment to pursue behavioral changes and innovation in technologies that evolve the market for water efficient devices and services. It requires strategic, focused implementation approaches that build from broad -based traditional programs. It requires that research be conducted to provide the basis for decisions. Lastly, it requires the support of local leaders to communicate a new value standard for water within this region. Metropolitan and its member agencies will implement the five strategies through a traditional program, a market acceleration program, and legislation and regulation. The five strategies include: • Use catalysts for market transformation. Metropolitan and member agencies will pursue market transformation to affect the market and consumer choices for water efficient devices and services. o Encourage action through outreach and education. Metropolitan and member agencies will provide outreach, educational workshops, and training classes through a range of media and formats which are essential to changing public perceptions of the value of water. o Develop regional technical capability. Metropolitan and member agencies will conduct research, facilitate information sharing, and/or provide technical assistance to member agencies and retail agencies to develop technical capabilities within the region for water budgeting, advanced metering infrastructure, ordinances, retail rate structures, and other conservation measures. • Build strategic alliances. Metropolitan and member agencies will fonn strategic alliances with partners to leverage resources, opportunities and existing momentum that support market transformation. o Advance water efficiency standards. Metropolitan and member agencies will work to advance water efficiency codes and standards to increase efficiency and reduce water waste. Successful market transformation requires the integrated use of all five strategies. It is implemented through three complementary programs: traditional and market acceleration programs, and legislation and regulation. When used together, these approaches can be catalytic and transform markets. Traditional Program: A traditional program of incentives, outreach, education, and training will be used to provide a foundation of water savings, establish baseline City of Seal Beach MALC� r . 2010 Urban Water Management Plan 2 - P y Section 2 Water Demand conditions, provide market data, and help determine devices and services that are primed for market acceleration. Implementation may include regional incentive programs, pilot programs, regional outreach, and research for a variety of devices and services. Market Acceleration Program: A portion of Metropolitan's resources will be used for market acceleration of devices and services that have potential for market change. Metropolitan will use a strategic focus for a specified time period to affect the market for a particular device or service. Tactics may include strategic outreach to manufacturers, retailers, contractors, and consumers; enhanced incentives; and collaboration on implementation. Legislation and Regulation: Are important tools and often the primary means for ensuring future water savings from devices and services. Regulation, ordinances and codes establish conditions that will ensure a minimum level of water efficiency for a particular device or service in the future. Markets are dynamic, and the influences on manufactures, retailers, and consumers are constantly changing. Progress made on changing consumer preferences a market share of efficient products is protected through legislation and regulations requiring a minimum efficiency standard. This benefits both water agencies and manufactures who invest in bringing water - efficiency technologies to the market. Legislation and regulation are also effective exit strategies to discontinue traditional incentive programs so that resources can be redirected to new technologies and approaches. Implementation of the combined programs, Traditional - Market Acceleration — Legislation and Regulation, will be closely coordinated between Metropolitan, member agencies and sub - agencies to maximize synergies. An adaptive management approach will be employed using research, implementation and evaluation to guide decisions on program activities and intensity. Periodic Review A periodic review of conservation actions to measure progress towards the water savings goals will be an integral component of the effort. The review will include work that is completed or in progress. It will consider factors that have affected the results as well as the opportunities to improve cost effectiveness and water savings. 2.5. Demand Projections 2.5.1. 25 Year Projections One of the main objectives of this UWMP is to provide an insight into the City's future water demand outlook. As discussed above, currently, the City's total water demand is 4,610 acre -feet comprising of 62% local groundwater and 38% imported water. As ALCOLM City of Seal Beach IRM 2010 Urban Water Management Plan 2 - Section 2 Water Demand illustrated in Table 2 -9, the City's water demand is expected to increase by 6% by 2020 and remain stable thereafter.

Low Income Household Projections One significant change to the UWMP Act since 2005 is the requirement for retail water suppliers to include water use projections for single - family and multifamily residential housing needed for lower income and affordable households. This requirement is to assist the retail suppliers in complying with the requirement under Section 65589.7 of the Government Code that suppliers grant a priority for the provision of service to housing units affordable to lower income households. A lower income household is defined as a household earning 80% of the County of Orange's median income or less. In order to identify the planned lower income housing projects within its service area, DWR recommends that retail suppliers may rely on Regional Housing Needs Assessment (RHNA) or Regional Housing Needs Plan information developed by the 2 California Department of Water Resources, Guidebook to Assist Urban Water Suppliers to Prepare a 2010 UWMP, Final (March 2011) +_w t City of Seal Beach ALCO t ' 2010 Urban Water Management Plan 2 - 4�IRNI Section 2 Water Demand local council of governments, the California Department of Housing and Community Development. The RHNA is an assessment process performed periodically as part of Housing Element and General Plan updates at the local level. Regional Council of Governments in California are required by the State Housing Element Law enacted in 1980 to determine the existing and projected regional housing needs for persons at all income levels. The RHNA quantifies the need for housing by income group within each jurisdiction during specific planning periods. The RHNA is used in land use planning, to prioritize local resource allocation and to help decide how to address existing and future housing needs. The RHNA consists of two measurements: 1) existing need for housing, and 2) future need for housing. The current RHNA planning period is January 1, 2006 to June 30, 2014 completed by the Southern California Association of Governments (SCAG) in 2007. The next RHNA which will cover the planning period of January 1, 2011 to September 30, 2021 is not expected to be completed until fall of 2012; therefore, the 2007 RHNA will be used for the purpose of this 2010 UWMP. Based on the 2007 Final Regional Housing Need Allocation Plan the projected housing need for low and very low income households (hereafter referred to as low - income) in the City of Seal Beach are 17.5% and 19.3 %, respectively or 36.8% combined. Therefore, from inference, it is estimated that approximately 36.8% of the projected water demands within the City's service area will be for housing needed for low income households. Table 2 -11 provides the projected water needs for low income residential units. The projected water demands shown here represent 36.8% of the projected water demand by customer type for residential customers provided in Table 2 -4 above.

Water Sources and Supply Reliability • 3.1. Overview The City's main sources of water supply are groundwater from the Lower Santa Ana River Groundwater Basin and imported water from Metropolitan through MWDOC. Today, the City relies on 62% groundwater and 38% imported. It is projected that through 2035, the water supply mix will remain roughly the same. The City works together with three primary agencies — Metropolitan, MWDOC, and OCWD to ensure a safe and high quality water supply, which will continue to serve the community in periods of drought and shortage. The sources of imported water supplies include the Colorado River and the State Water Project (SWP). Metropolitan's 2010 Integrated Water Resources Plan (IRP) update describes the core water resource strategy that will be used to meet full- service demands (non - interruptible agricultural and replenishment supplies) at the retail level under all foreseeable hydrologic conditions from 2015 through 2035. Local groundwater pumped from the City's wells is managed by OCWD. The Lower Santa Ana River Groundwater Basin is not adjudicated. In any given year, the amount of water which each City is allowed to pump out of the basin is based on the basin production percentage (BPP) established by OCWD. The OCWD sets the percentage of groundwater that an agency can pump based on their total potable water demand. The BPP fluctuates year by year but it is set uniformly for all Producers. Historically, BPP has ranged between approximately 60% to 80% depending on groundwater conditions, availability of recharge water supplies, and basin management objectives. For 2010/11, the BPP was set at 62 %. Production in excess of 62 percent of applicable demands is assessed under the basin equity assessment (BEA) with a production penalty, raising the cost of this supply to exceed imported water rates. As illustrated in Figure 3 -1, the BPP is assumed to remain at the conservative 62% level for the next 25 years. The remaining demand is projected to be met through imported water from Metropolitan/MWDOC and through a small portion of recycled water. The imported water supply numbers shown here represent only the amount of supplies projected to meet demands and not the full supply capacity. 4 The BPP was changed by OCWD in late April 2010 and effective July 2010 to 62 percent. 7"4 .,, x City of Seal Beach ALCM t 2010 Urban Water Management Plan 3 - PIRNI Section 3 Water Sources and Supply Reliability 100% •� . : .

Additionally, the City's projected supply and demand under various hydrological conditions are compared to determine the City's supply reliability for the 25 year planning horizon. This section satisfies the requirements of § 10631 (b) and (c), and 10635 of the Water Code. 3.2. Imported Water The City currently relies on 1,752 AFY of imported water wholesaled by Metropolitan through MWDOC to supplement local groundwater. Imported water represents approximately 38% of the City's total water supply. Metropolitan's principal sources of water originate from two sources - the Colorado River via the Colorado Aqueduct and the Lake Oroville watershed in Northern California through the State Water Project (SWP). This water is treated at the Robert B. Diemer Filtration Plant located north of Yorba Linda. Typically, the Diemer Filtration Plant receives a blend of Colorado River water from Lake Mathews through the Metropolitan Lower Feeder and SWP water through the Yorba Linda Feeder. The imported water is supplied to the City by the OC -35 Connection to Metropolitan system. The connection is located at Springdale Street and Westminster Avenue. This is a shared facility with City of Huntington Beach, which operates the facility and communicates with MWDOC and Metropolitan for the requested - City of Seal Beach ALCOLI� 2010 Urban Water Management Plan 3 - Section 3 Water Sources and Supply Reliability flows. The maximum capacity of the Connection for the City is 6.4 million gallons per day (MGD). 3.2.1. Metropolitan's 2010 Regional Urban Water Management Plan Metropolitan's 2010 Regional Urban Water Management Plan (RUWMP) reports on its water reliability and identifies projected supplies to meet the long -term demand within its service area. It presents Metropolitan's supply capacities from 2015 through 2035 under the three hydrologic conditions specified in the Act: single dry -year, multiple dry - years, and average year. Colorado River Supplies Colorado River Aqueduct supplies include supplies that would result from existing and committed programs and from implementation of the Quantification Settlement Agreement (QSA) and related agreements to transfer water from agricultural agencies to urban uses. Colorado River transactions are potentially available to supply additional water up to the CRA capacity of 1.25 MAF on an as- needed basis. State Water Project Supplies Metropolitan's State Water Project (SWP) supplies have been impacted in recent years by restrictions on SWP operations in accordance with the biological opinions of the U.S. Fish and Wildlife Service and National Marine Fishery Service issued on December 15, 2008 and June 4, 2009, respectively. In dry, below- normal conditions, Metropolitan has increased the supplies received from the California Aqueduct by developing flexible Central Valley /SWP storage and transfer programs. The goal of the storage /transfer programs is to develop additional dry-year supplies that can be conveyed through the available Banks pumping capacity to maximize deliveries through the California Aqueduct during dry hydrologic conditions and regulatory restrictions. In June 2007, Metropolitan's Board approved a Delta Action Plan that provides a framework for staff to pursue actions with other agencies and stakeholders to build a sustainable Delta and reduce conflicts between water supply conveyance and the environment. The Delta action plan aims to prioritize immediate short-term actions to stabilize the Delta while an ultimate solution is selected, and mid -term steps to maintain the Bay -Delta while the long -term solution is implemented. . State and federal resource agencies and various environmental and water user entities are currently engaged in the development of the Bay Delta Conservation Plan (BDCP), which is aimed at addressing the basic elements that include the Delta ecosystem restoration, water supply conveyance, and flood control protection and storage development. In evaluating the supply capabilities for the 2010 RUWMP, Metropolitan assumed a new Delta conveyance is fully operational by 2022 that would return supply City of Seal Beach IRNI E 2010 Urban Water Management Plan 3 - IRNI 1 Section 3 Water Sources and Supply Reliability reliability similar to 2005 condition, prior to supply restrictions imposed due to the Biological Opinions. Storage Storage is a major component of Metropolitan's dry year resource management strategy. Metropolitan's likelihood of having adequate supply capability to meet projected demands, without implementing its Water Supply Allocation Plan (WSAP), is dependent on its storage resources. In developing the supply capabilities for the 2010 RUWMP, Metropolitan assumed a simulated median storage level going into each of five -year increments based on the balances of supplies and demands. Supply Reliability Metropolitan evaluated supply reliability by projecting supply and demand conditions for the single- and multi -year drought cases based on conditions affecting the SWP (Metropolitan's largest and most variable supply).

The City relies on approximately 2,860 acre -feet of groundwater from the Lower Santa Ana River Groundwater Basin (Orange County Basin) each year. This local source of supply has historically met approximately 60 -80% of the City's total annual demand. In the effort to maximize local resources, Metropolitan has partnered with OCWD and MWDOC and its member agencies, which are groundwater producers in various programs to encourage the development of local resources. Metropolitan's Groundwater Replenishment Program is a program where a groundwater producer may purchase imported water from Metropolitan at a reduced rate when "surplus" water is available in lieu of extracting groundwater. This program indirectly replenishes the basin by avoiding pumping. This section describes the Lower Santa Ana River Groundwater Basin and the management measures taken by OCWD the basin manager to optimize local supply and minimize overdraft. Moreover, this section provides information on historical groundwater production as well as a 25 -year projection of the City's groundwater supply. City of Seal Beach 1v� ALCO 1� ,1; 2010 Urban Water Management Plan 3 - PIRNIF� Section 3 Water Sources and Supply Reliability 3.3.1. Lower Santa Ana River Groundwater Basin The Lower Santa Ana Groundwater Basin, also known as the Orange County Groundwater Basin (Basin) underlies the north half of Orange County beneath broad lowlands. The Basin covers an area of approximately 350 square miles, bordered by the Coyote and Chino Hills to the north, the Santa Ana Mountains to the northeast, the Pacific Ocean to the southwest, and terminates at the Orange County line to the northwest, where its aquifer systems continue into the Central Basin of Los Angeles County. The aquifers comprising this Basin extend over 2,000 feet deep and form a complex series of interconnected sand and gravel deposits. The Orange County Water District (OCWD) was formed in 1933 by a special legislative act of the State of California Legislature to protect and manage the County's vast, natural, underground water supply with the best available technology and to defend its water rights to the Orange County Groundwater Basin. This legislation is found in the State of California Statutes, Water — Uncodified Acts, Act 5683, as amended. The Basin is managed by OCWD under the Act, which functions as a statutorily - imposed physical solution. Section 77 of the Act states that, `nothing in this act contained shall be so construed as to affect or impair the vested right of any person, association or corporation to the use of water. s The Basin is managed by OCWD for the benefit of municipal, agricultural and private groundwater producers. The Basin meets approximately 60 to 70 percent of the water supply demand within the boundaries of OCWD. There are 19 major producers including cities, water districts, and private water companies, extracting water from the Basin serving a population of approximately 2.55 million. Groundwater levels are managed within a safe basin operating range to protect the long- term sustainability of the basin and to protect against land subsidence. In 2007, OCWD established a new methodology for calculating accumulated overdraft and establishing new full -basin benchmarks. Based on OCWD's 2009 Groundwater Management Plan, the optimal accumulated overdraft is between 100,000 and 434,000 AF. At the top of the range, OCWD will be able to provide at least three years of drought supply. An accumulated overdraft condition minimizes the localized high groundwater levels and increases ability to recharge storm events from the Santa Ana River. At an accumulated overdraft of 200,000 AF, the Basin is considered 99.7 percent full. OCWD estimates that the Basin can safely be operated on a short-term emergency basis with a maximum accumulated overdraft of approximately 500,000 AF. 5 Orange County Water District Act, Section 77. 6 MWDOC and Center for Demographics Research (2008) 7 The Report on Evaluation of Orange County Groundwater Basin Storage and Operational Strategy, published in February 2007, 4Q City of Seal Beach "1,PIRNI�A 2010 Urban Water Management Plan 3 - Section 3 Water Sources and Supply Reliability In an effort to eliminate long -term overdraft conditions, OCWD developed a comprehensive computer -based groundwater flow model to study and better understand the Basin's reaction to pumping and recharge. OCWD manages the Basin by establishing on an annual basis the appropriate level of groundwater production known as the Basin Production Percentage (BPP) as described below. 3.3.2. Basin Production Percentage No pumping right exists for the Orange County Basin. Total pumping from the basin is managed through a process that uses financial incentives to encourage groundwater producers to pump an aggregate amount of water that is sustainable without harming the Basin. The framework for the financial incentives is based on establishing the BPP which is the percentage of each Producer's total water supply that comes from groundwater pumped from the basin. Groundwater production at or below the BPP is assessed the Replenishment Assessment (RA). While there is no legal limit as to how much an agency could pump from the Basin, there is a financial disincentive to pumping above the BPP. Pumping above the BPP is also assessed a Basin Equity Assessment (BEA), which is calculated so that the cost of groundwater production is equal to MWDOC's melded rate. The BPP is set uniformly for all Producers by OCWD on an annual basis. The BPP for the 2008 -2009 water year (July 1, 2008 to June 30, 2009) was established at 69.0. The overall BPP achieved within OCWD for non - irrigation use in the 2008 -09 water year was equal to 72.5 percent. The BPP has recently been set at 62 percent for the 2010 -2011 water year. For the purpose of this UWMP, the BPP is assumed to be 62 percent for the entire 25 -year planning horizon (Table 3 -5). Table 3 -5: Current Basin Production Percentage • �;. r B asin•Name;° a ,, .Basin . Product on• percentage .r 4 .. ?i : a.. .. -. _ ..L:• _ . - ...•_' - Orange County Groundwater Basin 62% Total 62% The BPP is set based on groundwater conditions, availability of imported water supplies, and Basin management objectives. The BPP is also a major factor in determining the cost of groundwater production from the Basin for that year. When Metropolitan has an abundance of water, they may choose to activate their Groundwater Replenishment Program also known as In -Lieu Program, where imported water is purchased in -lieu of pumping groundwater. In some cases, OCWD encourages the pumping of groundwater that does not meet drinking water standards in order to protect water quality. This is achieved by using a financial incentive called the BEA Exemption. A BEA Exemption is used to encourage ALCOL�t City of Seal Beach IRNI 2010 Urban Water Management Plan 3 - Section 3 Water Sources and Supply Reliability pumping of groundwater that does not meet drinking water standards in order to clean up and contain the spread of poor quality water. OCWD uses a partial or total exemption of the BEA to compensate a qualified participating agency or Producer for the costs of treating poor - quality groundwater. When OCWD authorizes a BEA exemption for a project, it is obligated to provide the replenishment water for the production above the BPP and forgoes the BEA revenue that OCWD would otherwise receive from the producer. 3.3.3. Recharge Facilities Recharging water into the basin through natural and artificial means is essential to support pumping from the basin. Active recharge of groundwater began in 1949, in response to increasing drawdown of the basin and consequently the threat of seawater intrusion. In 1949, OCWD began purchasing imported Colorado River water from Metropolitan, which was delivered to Orange County via the Santa Ana River upstream of Prado Dam. The Basin's primary source of recharge is flow from the Santa Ana River. OCWD diverts river flows into recharge basins located in and adjacent to the Santa Ana River and its main Orange County tributary, Santiago Creek. Other sources of recharge water include natural infiltration and recycled water. Today OCWD owns and operates a network of recharge facilities that cover 1,067 acres. An increase in recharge capacity of greater than 10,000 AFY occurred with the addition of the La Jolla Recharge Basin which came online in 2008. The La Jolla Recharge Basin is a 6 -acre recharge basin. One of OCWD's primary efforts has been the control of seawater intrusion into the Basin, especially via the Talbert and Alamitos seawater intrusion barriers. OCWD began addressing the Alamitos Gap intrusion by entering a partnership in 1965 with the Los Angeles County Flood Control District to operate injection wells in the Alamitos Gap. Operation of the injection wells forms a hydraulic barrier to seawater intrusion. To address seawater intrusion in the Talbert Gap, OCWD constructed Water Factory 21, a plant that treated secondary- treated water from the Orange County Sanitation District (OCSD) to produce purified water for injection. Water Factory 21 operated for approximately 30 years until it was taken off line in 2004. It was replaced by an advanced water treatment system, the Groundwater Replenishment System (GWRS). The GWRS is a cooperative project between OCWD and OCSD that began operating in 2008. Secondary- treated wastewater from OCSD undergoes treatment consisting of microfiltration, reverse osmosis, and advanced oxidation with ultraviolet light and hydrogen peroxide. It is the largest water purification project of its kind, Phase 1 of the GWRS began operating in 2008 with a capacity of purifying 72,000 AFY of water. The GWRS provides recharge water for the Talbert Injection Barrier as well as to recharge basins in the City of Anaheim. The Expanded Talbert Injection Barrier included 8 new injection wells which operation began in 2008. The GWRS increased reliable, local water supplies available for barrier injection from 5 mgd to 30 mgd. 7'4'T City of Seal Beach r MALCOL( j 1RNI 2' 2010 Urban Water Management Plan 3 - Section 3 Water Sources and Supply Reliability 3.3.4. Metropolitan Groundwater Replenishment Program OCWD, MWDOC, and Metropolitan have developed a successful and efficient groundwater replenishment program to increase storage in the Orange County Groundwater Basin. The Groundwater Replenishment Program allows Metropolitan to sell groundwater replenishment water to OCWD and make direct deliveries to agency distribution systems in lieu of producing water from the groundwater basin when surplus water is available. This program indirectly replenishes the basin by avoiding pumping. In the in -lieu program, OCWD requests an agency to halt pumping from specified wells. The agency then takes replacement water through its import connections, which is purchased by OCWD from Metropolitan (through MWDOC). OCWD purchases the water at a reduced rate, and then bills the agency for the amount it would have had to pay for energy and the Replenishment Assessment (RA) if it had produced the water from its wells. The deferred local production results in water being left in local storage for future use. In 2008 and 2009, OCWD did not utilize replenishment water because such water was not available to purchase from Metropolitan. 3.3.5. Metropolitan Conjunctive Use Program Since 2004, OCWD, MWDOC, and participating producers have participated in Metropolitan's Conjunctive Use Program (known as the Metropolitan's Long -Term Groundwater Storage Program or Metropolitan CUP). This program allows for the storage of Metropolitan water in the Orange County groundwater basin. The existing Metropolitan storage program provides for Metropolitan to store 66,000 AF of water in the basin in exchange for Metropolitan's contribution to improvements in basin management facilities. These improvements include eight new groundwater production wells, improvements to the seawater intrusion barrier, construction of the Diemer Bypass Pipeline. This water can be withdrawn over a three -year time period. The preferred means to store water in the Metropolitan storage account has been through the in -lieu deliveries to participating groundwater producers. 3.3.6. Historical Groundwater Production Since its founding, OCWD has grown in size from 162,676 to 229,000 acres. Groundwater pumping from the basin has grown from approximately 150,000 AFY in the mid -1950s to over 300,000 AFY. During the water year July 2008 to June 2009, total basin production for all agencies was approximately 324,147 acre -feet (AF). The City obtains groundwater pumped from three wells owned and operated by the City and managed by OCWD.

Table 3 -6 shows the City's recent groundwater production from the Basin in the past five years from 2005 to 2009. During certain seasons of 2005, 2006, and 2007, OCWD has operated the In -lieu Program with Metropolitan by purchasing water from Metropolitan to meet demands of member agencies rather than pumping water from the groundwater basin. In 2008 and 2009, OCWD did not utilize in -lieu water because such water was not available to purchase from Metropolitan.

Projections of Groundwater Production The mission of the OCWD is to provide local water retailers with a reliable, adequate, high quality water supply at the lowest reasonable cost in an environmentally responsible manner. Efforts have been made to develop and secure new supplies. Also in December 2008, OCWD secured the rights to divert and use up to 362,000 AFY of Santa Ana River water through a decision of the State Water Resources Control Board. Description to other recent OCWD projects can be found in OCWD's 2009 GWMP. Based on the annual MWDOC survey completed by each Producer in the spring of 2008, the estimated demand for groundwater in the OCWD boundary will increase from 519,000 AFY in 2015 to 558,000 AFY in 2035 representing a 7.5 percent increase over a 20 year period. OCWD's estimated total annual groundwater production for the water year 2010 -2011 is 295,000 AF based on a BPP of 62 percent and includes 22,000 AF of production from water quality improvement projects. The City obtains about 2,853 AFY from three wells, from an average depth of 800 feet. The rest of The City's water is purchased from MWDOC. Table 3 -7 shows the current and planned groundwater supply. There has been some saline intrusion into the upper aquifers of the Basin, but it has not affected the strata from which the City wells produce. Water quality is within standards set for acceptable drinking water by the federal government and the California Department of Health Services. It should be noted that groundwater pumping rights are determined annually by Orange County Water District. 9 2008 -2009 Engineer's Report on Groundwater conditions, Water Supply and Basin Utilization in the Orange County Water District, February 2010 k r' . .

The well pump, driven by a natural gas engine, pumps directly into the Beverly Manor Reservoir. It has a capacity of 2,000 gpm. o Bolsa Chica Well -This well, constructed in 1979, is located on Bolsa Chica Road south of the San Diego Freeway. The well pump can be driven with an electric motor as well as a natural gas engine. The well discharge pressure is maintained by varying the speed of electric motor by means of a variable frequency drive or by a Murphy controller acting on the natural gas engine. The maximum output into the distribution system is 2,800 gpm at 68 psi. ® Leisure World Well - Leisure World Well is located behind a fenced enclosure in Leisure World on Beverly Manor Road. Well pump is electrical motor - driven. The well pumps into Beverly Manor Reservoir but has the ability to pump directly into the Leisure World Distribution System. The City is currently planning to construct a new well in the College Park East area near the Old Ranch Golf Course. The new well is further inland than the other three wells and will increase supply reliability to the College Park East area in case of distribution system outages in Bolsa Chica Road, or across the San Diego Freeway west of Seal Beach Boulevard. Table 3 -7 shows the amount of groundwater projected to be pumped from the Basin by the City in the next 25 years. The BPP is assumed to remain at 62 percent for the entire planning horizon. Because the BEA exemption agreement between Garden Grove and OCWD has expired, it is assumed here that OCWD will disallow the agreement to continue and the City's groundwater production will stay within the BPP without the BEA adjustment. However, the City is making improvements to the blending facilities and is planning to appeal the BEA exemption once the interim blending system is in place.

Supply Reliability 3.4i. Overview It is required that every urban water supplier assess the reliability to provide water service to its customers under normal, dry, and multiple dry water years. The City depends on a combination of imported and local supplies to meet its water demands and has taken numerous steps to ensure it has adequate supplies. Development of groundwater and desalination opportunities augments the reliability of the imported water system. There are various factors that may impact reliability of supplies such as legal, environmental, water quality and climatic which are discussed below. The water supplies are projected to meet full - service demands; Metropolitan's 2010 RUWMP finds that Metropolitan is able to meet with existing supplies, full - service demands of its member agencies starting 2015 through 2035 during normal years, single dry year, and multiple dry years. Metropolitan's 2010 Integrated Water Resources Plan (IRP) update describes the core water resource strategy that will be used to meet full - service demands at the retail level under all foreseeable hydrologic conditions from 2015 through 2035. The foundation of Metropolitan's resource strategy for achieving regional water supply reliability has been to develop and implement water resources programs and activities through its IRP preferred resource mix. This preferred resource mix includes conservation, local resources such as water recycling and groundwater recovery, Colorado River supplies and transfers, SWP supplies and transfers, in- region surface reservoir storage, in- region groundwater storage, out -of- region banking, treatment, conveyance and infrastructure improvements. MWDOC is reliant on Metropolitan for all of its imported water. With the addition of planned supplies under development, Metropolitan's 2010 RUWMP finds that Metropolitan will be able to meet full- service demands from 2015 through 2035, even under a repeat of the worst drought. Table 3 -8 shows the reliability of the wholesaler's supply for single dry year and multiple dry year scenarios.

Factors Impacting Reliability The Act requires a description of the reliability of the water supply and vulnerability to seasonal or climatic shortage. The City relies on import supplies provided by Metropolitan through MWDOC. The following are some of the factors identified by Metropolitan that may have an impact on the reliability of Metropolitan supplies. Environment— Endangered species protection needs in the Sacramento -San Joaquin River Delta have resulted in operational constraints to the SWP system. The Bay - Delta's declining ecosystem caused by agricultural runoff, operation of water pumps and other factors has led to historical restrictions in SWP supply deliveries. SWP delivery restrictions due to the biological opinions resulted in the loss of about one -third of the available SWP supplies in 2008. Legal — Listings of additional species under the Endangered Species Act and new regulatory requirements could impact SWP operations by requiring additional export reductions, releases of additional water from storage or other operational changes impacting water supply operations. Additionally, the Quantification Settlement Agreement has been challenged in courts and may have impacts on the Imperial Irrigation District and San Diego County Water Authority transfer. If there are negative impacts, San Diego could become more dependent on the Metropolitan supplies. Water Quality —Water imported from the Colorado River Aqueduct (CRA) contains high level of salts. The operational constraint is that this water needs to be blended with SWP supplies to meet the target salinity of 500 mg/L of total dissolved solids (TDS). Another water quality concern is related to the quagga mussel. Controlling the spread and impacts of quagga mussels within the Colorado River Aqueduct requires extensive maintenance and results in reduced operational flexibility. Climate Change — Changing climate patterns are expected to shift precipitation patterns and affect water supply. Unpredictable weather patterns will make water supply planning even more challenging. The areas of concern for California include the reduction in Sierra Nevada snowpack, increased intensity and frequency of extreme weather events, and rising sea levels causing increased risk of levee failure. ti 1ALC�L11' City of Seal Beach p E 2010 Urban Water Management Plan 3 - � lRlVl,ur,, • Section 3 Water Sources and Supply Reliability Legal, environmental, and water quality issues may have impacts on Metropolitan supplies. It is felt, however, that climatic factors would have more of an impact than the others. Climatic conditions have been projected based on historical patterns; however severe pattern changes may occur in the future. Table 3 -10 shows the factors resulting in inconsistency of supply.

Water Quality Imported Water - Metropolitan is responsible for providing water of a high quality throughout its service area. The water that Metropolitan delivers is tested both for currently regulated contaminants and for additional contaminants of concern as over 300,000 water quality tests are conducted each year to regulate the safety of its waters. Metropolitan's supplies originate primarily from the Colorado River Aqueduct (CRA) and from the State Water Project (SWP). A blend of these two sources, proportional to each year's availability of the source, is then delivered throughout Metropolitan's service area. Metropolitan's primary sources face individual water quality issues of concern. The CRA water source contains a higher level of total dissolved solids (TDS) and a lower level of • organic material while the SWP contains a lower TDS level while its level or organic materials is much higher, lending to the formation of disinfection byproducts. To remediate the CRA's high level of salinity and the SWP's high level of organic materials, Metropolitan has been blending CRA water with SWP supplies as well as implementing updated treatment processes to decrease the disinfection byproducts. In addition, Metropolitan has been engaged in efforts to protect its Colorado River supplies from threats of uranium, perchlorate, and chromium VI while also investigating the potential water quality impact of emerging contaminants, N- nitrosodimethylamine (NDMA) and pharmaceuticals and personal care products (PPCPs). Metropolitan has assured its ability to overcome the above mentioned water quality concerns through its protection of source waters, implementation of renovated treatment processes, and blending of its two sources. While unforeseeable water quality issues could alter reliability, Metropolitan's current strategies ensure the deliverability of high quality water. g,` ;-, City of Seal Beach ALCO 1 2010 Urban Water Management Plan 3 - IRNI • Section 3 Water Sources and Supply Reliability Groundwater - The Orange County Water District (OCWD) is responsible for managing the Orange County Groundwater Basin. To maintain groundwater quality, OCWD conducts an extensive monitoring program that serves to manage the basin's groundwater production, control groundwater contamination, and comply with all necessary laws and regulations. A network of nearly 700 wells provides OCWD a source for samples, which are tested for a variety of purposes. The District collects 600 to 1,700 samples each month to monitor the quality of the basin's water. These samples are collected and tested according to approved federal and state procedures as well as industry - recognized quality assurance and control protocols. OCWD recognizes the importance of maintaining the basin's high water quality. OCWD's 2009 Groundwater Management Plan Update includes a section labeled, "Water Quality Management," which discusses the water quality concerns as well as management programs that OCWD is currently involved with.

Normal -Year Reliability Comparison The City has entitlements and/or written contracts to receive imported water from Metropolitan via the regional distribution system. Although pipeline capacity rights do not guarantee the availability of water, per se, they do guarantee the ability to convey water when it is available to the Metropolitan distribution system. All imported water supplies assumed in this section are available to the City from existing water transmission facilities. Table 3 -12 shows supply and demand under normal year conditions. Water supplies are projected to be available from Metropolitan; however, it is not included here since projected supplies meet projected demands. 10 The information in this section is referenced from the Groundwater Management Plan 2009 Update "Groundwater Monitoring" section (pages 3 -1 through 3 -20) and "Water Quality Management" section (pages 5 -1 through 5 -30).

Demand Management Measures 4.1. Overview Water conservation, often called demand -side management, can be defined as practices, techniques, and technologies that improve the efficiency of water use. Such practices are referred to as demand management measures (DMM). Increased efficiency expands the use of the water resource, freeing up water supplies for other uses, such as population growth, new industry, and environmental conservation. The increasing efforts in water conservation are spurred by a number of factors: growing competition for limited supplies, increasing costs and difficulties in developing new supplies, optimization of existing facilities, delay of capital investments in capacity expansion, and growing public support for the conservation of limited natural resources and adequate water supplies to preserve environmental integrity. The City recognizes the importance of water conservation and has made water use efficiency an integral part of water use planning. The City has been a signatory to the California Urban Water Conservation Council's (CUWCC) Best Management Practices (BMPs) Memorandum of Understanding (MOU) since 2000. DMMs as defined by the Act con-espond to the CUWCC's BMPs. The City is currently implementing all applicable DMMs described in the Act. This section of the UWMP satisfies the requirements of § 10631 (f) & (j). It describes how each DMM is being implemented by the City and how the City evaluates the effectiveness of the DMMs implemented. This section also provides an estimate of existing conservation savings where information is available. 4.2. Water Use Efficiency Programs As Signatory to the CUWCC MOU, the City has committed to use good -faith efforts to implement the 14 cost - effective BMPs. The City has implemented and is actively participating in many water conservation activities. A Water Conservation Ordinance was adopted by the City Council in 2009 as Ordinance No. 1586 amending the Seal Beach Municipal Code by revising and supplementing the City's Water Conservation Provisions. Moreover, as a member agency of MWDOC, the City actively participates in various Metropolitan residential and CII rebate programs, as well as school and public education and outreach programs, and other programs administered by MWDOC. MWDOC ALCO1 City of Seal Beach IRNIt 2010 Urban Water Management Plan 4 - Section 4 Demand Management Measures implements many of the urban water conservation BMPs on behalf of its member agencies. MWDOC's 2010 RUWMP should be referred to for a detailed discussion of each regional BMP program. The City works cooperatively with MWDOC for technical and financial support needed to facilitate meeting the terms of the MOU. MWDOC's current Water Use Efficiency Program, detailed in their 2010 RUWMP, implemented on behalf of its member agencies following three basic focuses: 1. Regional Program Development — MWDOC develops, obtains funding for, and implements regional BMP programs on behalf of all retail water agencies in Orange County. 2. Local Program Assistance - MWDOC assists retail agencies to develop and implement local programs within their individual service areas. 3. Research and Evaluation — MWDOC conducts research programs which allow an agency to measure the water savings benefits of a specific program and then compare those benefits to the costs of implementing the program in order to evaluate the economic feasibility of the program.

DMM 1: Water Survey Programs for Single - Family Residential and Multi - Family Residential Customers Residential Survey Program: — The City, in cooperation with Metropolitan and MWDOC had offered free residential water use surveys to single - family and multi - family customers. The City has phased out the formal survey program and currently conducts residential survey on an as- needed basis. When a high bill complaint is received, staff is sent out to conduct an audit. The City's finance department is in the process of developing an inquiry program to sort billing records by water use within sectors, so that letters offering the free surveys can be mailed to the highest water users. If a customer does not participate and remains on the highest water use list the subsequent year, the customer would receive additional letters offering a water use survey. The City also participates in regional landscape programs aimed at helping residential and small commercial customers to be more water efficient through MWDOC. A thorough site inspection that includes a landscape survey is conducted as part of the Smart Timer and Rotating Nozzle Rebate Programs. Details of these residential landscape water use efficiency programs are provided below. Smart Timer Rebate Program - The Smart Timer Rebate Program started in FY 2004/05. Under this regional program, residential and commercial properties, including Homeowners Association (HOA) common areas, are eligible for a rebate when they purchase and install a weather -based irrigation controller which has the potential to save 41 gallons per day per residence and reduce runoff and pollution by 49 %. Once residents are enrolled in the rebate program, a detailed residential outdoor water survey is conducted to inspect the irrigation system, distribution uniformity, and irrigated area. Water savings from the program can be estimated from information obtained from the water surveys pre- and post- installation of the Smart Timer. As part of the MWDOC Grant for the smart timers, a site audit and inspection is required and provided by contract through MWDOC. As of FY 2010 -11, one customer (a commercial customer) has taken advantage of this program. The cumulative water savings from this participation is 1.18 AF. Rotating Nozzle Rebate Program — This rebate program started in 2007 and is offered to both residential and commercial customers. Through this program, site owners will purchase and install rotary nozzles in existing irrigation systems. Following the submittal of a rebate application, water bill, and original purchase receipt, MWDOC will direct a third party installation verification contractor to perform installation verifications on up to 100% of the sites that installed devices. As of FY 2010/11, 115 rotating nozzles have been installed at residential properties and 291 at commercial properties representing a combined water savings of 3.71 acre -feet. r oQ�= City of Seal Beach RM t MIALCOL , Management Urban W Mana ement Plan 4 - r� FI Section 4 Demand Management Measures Synthetic Turf Rebate Program — Through this program, residential and commercial customers of participating retail water agencies are eligible to receive rebate money for qualifying synthetic turf projects. To date 817 sq. ft. of turf grass have been replaced by synthetic turf on residential properties translating to a savings of 0.34 acre -feet. California Friendly Landscape Training (Residential) - The California Friendly Landscape Training provides education to residential homeowners and professional landscape contractors on a variety of landscape water efficiency practices they can employ. These classes are hosted by MWDOC and /or the retail agencies to encourage participation across the county. The residential training program consists of either a half - day Mini Class or individual, topic - specific, four -hour classes. ® Methods to Evaluate Effectiveness — MWDOC and City staff track participation and water savings of each program by fiscal year. 4.2.2. DMM 2: Residential Plumbing Retrofit Regional Plumbing Retrofit Programs - The City participated in MWDOC's regional showerhead distribution program which began in 1991. To determine whether the 75% saturation requirement was achieved within Orange County, a saturation study was conducted by MWDOC and Metropolitan and completed in 2001. Data was obtained through telephone surveys and on -site inspections. Using the saturation findings of the study, MWDOC estimates that today low flow showerhead saturation is at nearly 100% for single - family homes and at 94% for multi - family homes. Additionally, the City participated in MWDOC's regional ultra low flow toilet (ULFT) rebate program which began in 1992 and ended in 2009. A total of 2,396 ULFTs were distributed under this program to single - family and multi - family homes representing a cumulative water savings of 915 acre -feet. The high efficiency toilet (HET) rebate program has since replaced the ULFT program as discussed under DMM 14. As a benchmark, prior to the year 1992 when the program started the City had approximately 4,500 combined single & multi - family residential customers (the City does not have separate data on single /multi - family accounts). ® Methods to Evaluate Effectiveness - The 2001 Residential Plumbing Fixture Saturation Study done by Metropolitan and MWDOC determined Orange County to be above the required saturation for plumbing fixtures. 4.2.3. DMM 3: System Water Audits, Leak Detection and Repair The City has conducted water audits and leak detection and repair since 1991. The City performs water audit and leak detection when it receives high bill complaints from customers. City of Seal Beach MALC001 2010 Urban Water Management Plan 4 - PIRNIE, Section 4 Demand Management Measures Since the City is located in an earthquake zone, it has incorporated the system water audit and leak detection, and meter calibration (production and customer meters) programs into its utility operations. City staff is trained at AWWA sponsored training programs. On average, City Water Department crews spend about 30 days surveying approximately 10 miles of main and laterals per year. The City replaces and/or calibrates a minimum of 250 meters per year, which is approximately 5% of the total meters in the system. The City also has an annual valve exercise program, to ensure that interconnections with adjacent utilities actually work. The City repairs leaks in the distribution system as they occur. In coordination with the Orange County Fire Authority, the City water department complied with amendments to California Code of Regulations Title 19, Division 1, Chapter 9, pertaining to standardization of fire hydrants and associated fire protection equipment. o Methods to Evaluate Effectiveness - The water billing staff will annually review the data records to confirm that the unaccounted for water losses stay under 8 %. 4.2.4. DMM 4: Metering with Commodity Rates The City is fully metered for all customer sectors, including separate meters for single - family residential, commercial, as well as City owned meters. The City will continue to install and read meters on all new services, and will continue to conduct its meter calibration and replacement program. The City has completed the installation of meters on the few City owned facilities including dedicated landscape meters. Customers are billed bimonthly by volume of use. The City employs a three -tier inclining block rate structure as described in more detail in Section 4.2.11. o Estimated Conservation - Metered accounts may result in a 20% reduction in demand compared to non- metered accounts. o Methods to Evaluate Effectiveness - Periodic review of customer water use, comparing current water use per capita with historic data. 4.2.5. DMM 5: Large Landscape Conservation Programs and Incentives The City collaborates with its wholesaler, MWDOC on several large landscape water use efficiency programs. Many of MWDOC's landscape water use efficiency programs target both residential and commercial customers as described under DMM 1. MWDOC also offers programs in Orange County which specifically assist large landscape customers as follows: Water Smart Landscape Program — This is a MWDOC- administered program which started in 2004. The program is a free water management training program sponsored by MWDOC and Metropolitan and offered to CII customers with dedicated irrigation i t`` ` City of Seal Beach ALCO 1 2010 Urban Water Management Plan 4 - IRNI Section 4 Demand Management Measures meters. The program also helps create site specific water budgets and track monthly water use for each participating site. The program is designed to do the following: • Assist water agencies in meeting the landscape irrigation management requirements of the CUWCC's BMP #5; • Assist cities and the County in meeting Integrated Waste Management Act goals (AB 979) to reduce the volume of waste and to recycle organic materials for the benefit of the landscape; and • Assist cities and the County in identifying landscape run -off sites and providing site -by -site remedies. Homeowner associations (HOAs) managing dedicated landscape irrigation meters are the primary target audience for participation in this program; however, city and school district landscapes also participate. California Friendly Landscape Training (Professional) — The California Friendly Landscape Training provides education to residential homeowners and professional landscape contractors on a variety of landscape water efficiency practices they can employ. These classes are hosted by MWDOC and /or the member agencies to encourage participation across the county. The Professional Training Program course consists of four consecutive classes in landscape water management, each building upon principles presented in the preceding class. Each participant receives a bound handbook containing educational materials for each class. These classes are offered throughout the year and taught in both English and Spanish languages. In addition, the City takes advantage of regional and local efforts which target and market to large landscape properties including bill inserts, direct marketing efforts, ads in various publications, educational seminars /symposiums for property owners, and presentations at Homeowners Associations (HOAs) board meetings. Water Efficient Landscape Ordinance — The City adopted a Water Efficient Landscape Ordinance (Ordinance No. 1588) to establish an alternative landscape model acceptable under AB 1881 as being at least as effective as the State Model Water Efficient Landscape Ordinance. The Ordinance establishes requirements related to planting, irrigation, and landscape- related improvements applicable to new landscape installations or landscape rehabilitation projects of certain sizes. The ordinance puts in place Landscape Water Use Standards and Guidelines. For example, for applicable landscape installation or rehabilitation projects, the Estimated Applied Water Use allowed for the landscaped area shall not exceed the Maximum Applied Water Allowance calculated using an ET adjustment factor of 0.7. City of Seal Beach ALCOL�v1„ 2010 Urban Water Manageme Pl 4 - IRNIE, Section 4 Demand Management Measures 0 Methods to Evaluate Effectiveness and Estimated Savings — MWDOC keeps track of program participation and estimated water savings based on number of rebates provided. 4.2.6. DMM 6: High- Efficiency Washing Machine Rebate Programs The City participates in the SoCal Water Smart residential rebate program offered by Metropolitan. This program offers financial incentives to single- family and multifamily residential customers through the form of a rebate. Orange County residents are eligible to receive an $85 rebate when they purchase a new High Efficiency Clothes Washer (HECW). This program began in 2001 and is sponsored by MWDOC, Metropolitan, and local retail water agencies. Rebates are available on a first -come, first -served basis, while funds last. Participants must be willing to allow an inspection of the installed machine for verification of program compliance. To qualify for a rebate, the HECW must have a water factor of 4.0 or less. An HECW with a water factor of 4 will use approximately 15 gallons of water per load compared to a conventional top- loading clothes washer which can use 40 gallons or more per load. Depending on use, these machines can save 10,000 gallons of water per year. Participants are encouraged to contact their local gas and/or electric utility as additional rebates may be available. As of FY 2010 -11, the City has given out 350 high - efficiency washing machine rebates to its customers. This equates to a water savings of 42.9 acre -feet. Methods to Evaluate Effectiveness — MWDOC keeps track of program participation and estimated water savings based on number of rebates provided. 4.2.7. DMM 7: Public Information Programs The City promotes water conservation and other resource efficiencies in coordination with Metropolitan and MWDOC. The City distributes public information through bill inserts, brochures, and special events every year. City water bills has been redesigned to show gallons used per day for the last billing period compared to the same period the previous year (previously, the bill only indicated total billing period usage in billing units (one hundred cubic feet of water, which is 748 gallons). The City maintains a World Wide Web Home Page for Public Works Department, which includes information on water usage, conservation, and other resource issues. MWDOC's Regional Public Information Programs MWDOC currently offers a wide range of public information programs in Orange County • in collaboration with its member agencies including the City of Seal Beach. Current regional public information programs within the MWDOC's service area are summarized below. City of Seal Beach >ALC 2010 Urban Water Management Plan 4 - Section 4 Demand Management Measures Water Facility Inspection Trip Program - The inspection trip program is sponsored by MWDOC and Metropolitan. Each year, Orange County elected officials, residents, business owners, and community leaders are invited to attend educational inspection trips to tour key water facilities throughout the state of California. The goal is to educate members of our community about planning, procurement and management of southern California's water supply and the issues surrounding delivery and management of this vital resource. O.C. Water Hero Program - The goal of this program is to engage children in water use efficiency activities while facilitating discussion with friends and family members about how to save water. Any Orange County child can become a Water Hero by pledging to save 20 gallons of water per day. In exchange for their pledge, they receive a free Water Hero kit, which includes a variety of fun, water - saving items like a 5- minute shower timer and "fix -it" ticket pad for busting water wasters. To become a Superhero, a student must get their parents to also pledge to save 20 gallons of water per day. To date, more than 13,000 children in Orange County have become Water Heroes and more than 4,000 have become Superheroes. eCurrents - This monthly electronic newsletter is designed to keep MWDOC's 28 member agencies, residents and businesses, stakeholder groups, opinion leaders, and others apprised of MWDOC news, programs, events, and activities. The publication also serves to keep readers informed about regional, state, and federal issues affecting water supply, water management, water quality, and water policy and regulation. Water Advisory Committee of Orange County (WACO) - WACO was formed in 1983 to facilitate the introduction, discussion, and debate of current and emerging water issues among Orange County policymakers and water professionals. The committee's membership has evolved to include elected officials and management staff from Orange County cities and water districts, engineers, attorneys, consultants, and other industry professionals. Monthly meetings are open to the public and are typically held on the first Friday of each month at 7:30 a.m. o Estimated Conservation - The City has no method to quantify the savings of this DMM but believes that this program is in the public's interest.

MWDOC, on behalf of the City, provides educational materials for several grade levels, State and County water system maps, posters, workbooks, interactive computer software, and videos, and sponsors teachers' Project Water Education for Teachers (WET) training, science fairs, and water conservation contests. MWDOC's Regional School Education Programs Water Education School Program - One of the most successful and well - recognized water education curriculums in Southern California is MWDOC's Water Education School Program. For more than 30 years, School Program mascot "Ricki the Rambunctious Raindrop" has been educating students in grades K -5 about the water cycle, the importance and value of water, and the personal responsibility we all have as environmental stewards. The School Program features assembly -style presentations that are grade- specific and performed on -site at the schools. The program curriculum is aligned with the science content standards established by the State of California. Since its inception in 1973, nearly three million Orange County students have been educated through the School Program. In 2004, MWDOC formed an exciting partnership with Discovery Science Center that has allowed both organizations to reach more Orange County students each year and provide them with even greater educational experiences in the areas of water and science. Discovery Science Center currently serves as the School Program administrator, handling all of the program marketing, bookings, and program implementation. During the 2010- 11 school year, more than 70,000 Orange County students will be educated through the program. Water Education Poster & Slogan Contest - Each year, MWDOC holds a Water Education Poster and Slogan Contest to increase water awareness. To participate, children in grades K -6 develop posters and slogans that reflect a water awareness message. The goal is to get children thinking about how they can use water wisely and to facilitate discussion about water between children and their friend, parents, and teachers. Each year, more than 1,500 poster and slogan entries are received through the contest. During a special judging event, approximately 16 posters and 10 slogans are selected as the winners. All of the winners — and their parents, teachers, and principals — are invited to attend a special awards ceremony with Ricki Raindrop at Discovery Science Center.

DMM 13: Water Waste Prohibition The City Council has adopted Ordinance 1586 in 2009 revising and supplementing the City's water conservation provisions. The ordinance has permanent water conservation measures dealing with leak repair, runoff, limits on watering hours, limit on watering duration, serving water at restaurants, ornamental water fountains, single pass cooling systems, car washes and laundries and washing vehicles and equipment. In addition, the ordinance has provisions dealing with three water conservation phases as described in Section 5. The City has made significant efforts to notify the public of the new ordinance and educated them on the new provisions. Water customers were notified via billing inserts about the ordinance and the conservation measures required therein. There have been newspaper articles and internet articles regarding the ordinance. The ordinance is highlighted on the City Web Page. All Public Works Department vehicles have magnetic signs promoting water conservation. The City sent letters to all restaurant owners in the City advising them of the restrictions on serving water to customers. The letters included table placards to notify the public of the reason water was not being served. City staff has been trained on the provisions of the ordinance. Any time they observe a violation they take the opportunity to education the public on the requirements of the ordinance. The enforcement provisions of the ordinance allow for a three step enforcement program. The first step is a written notice from the City outlining the violation and the corrective measures needed. The second step allows for a 15% surcharge added to the water bill of ''" °` ' =" City of Seal Beach AgALC� 2010 Urban Water Management Plan 4 - , _�IRN I Section 4 Demand Management Measures the offending customer.

Overview Recent water supply challenges throughout the American Southwest and the State of California have resulted in the development of a number of policy actions that water agencies would implement in the event of a water shortage. In southern California, the development of such policies has occurred at both the wholesale and retail level. This section describes how new and existing policies that Metropolitan, MWDOC and the City have in place to respond to water supply shortages, including a catastrophic interruption and up to a 50 percent reduction in water supply. 5.2. Shortage Actions Metropolitan As an importer of water from multiple sources, including both the Colorado River and Sierra Nevada, a number of water supply challenges have impacted the reliability of Metropolitan's imported supplies. In response to these challenges, Metropolitan has implemented existing policies as well as developed new ones. The first action that Metropolitan implements in the event of a water shortage is the suspension and/or reduction of its interruptible supplies, which are supplies sold at a discount in return for the buyers agreeing to be the first to be cutback in the event of a shortage. Metropolitan currently has two interruptible programs for agricultural users and groundwater replenishment, under which supplies were either suspended or reduced in 2007. In addition, in preparation for the possibility of being unable to the meet "firm demands" (non - interruptible supplies) of its member agencies, in February 2008, the Metropolitan's Board of Directors (Board) adopted the Water Supply Allocation Plan (WSAP), which was subsequently updated in June 2009. Metropolitan's plan includes the specific formula for calculating member agency supply allocations and the key implementation elements needed for administering an allocation. Metropolitan's WSAP is the foundation for the urban water shortage contingency analysis required under Water Code Section 10632 and is part of Metropolitan's 2010 RUWMP. Metropolitan's WSAP was developed in consideration of the principles and guidelines described in Metropolitan's 1999 Water Surplus and Drought Management Plan ALCM I ti' City of Seal Beach IRNI 2010 Urban Water Management Plan 5 - Section 5 Water Supplies Contingency Plan (WSDM), with the objective of creating an equitable needs -based allocation. The plan's formula seeks to balance the impacts of a shortage at the retail level while maintaining equity on the wholesale level for shortages of Metropolitan supplies of up to 50 percent. The formula takes into account: impact on retail customers and the economy; growth and population; changes in supply conditions; investments in local resources; demand hardening aspects of non - potable recycled water use; implementation of conservation savings program; participation in Metropolitan's interruptible programs; and investments in facilities. The formula is calculated in three steps: based period calculations, allocation year calculations, and supply allocation calculations. The first two steps involve standard computations, while the third section contains specific methodology developed for the WSAP. Step 1: Base Period Calculations — The first step in calculating a water supply allocation is to estimate water supply and demand using a historical based period with established water supply and delivery data. The base period for each of the different categories of demand and supply is calculated using data from the three most recent non - shortage years, 2004 -2006. Step 2: Allocation Year Calculations — The next step in calculating the water supply allocation is estimating water needs in the allocation year. This is done by adjusting the base period estimates of retail demand for population or economic growth and changes in local supplies. Step 3: Supply Allocation Calculations — The final step is calculating the water supply allocation for each member agency based on the allocation year water needs identified in Step 2. Each element and its application in the allocation formula are discussed in detail in Metropolitan's WSAP. In order to implement the WSAP, the Metropolitan Board makes a determination on the level of the regional shortage, based on specific criteria, in April each year. If it is determined allocations are necessary, they go into effect in July for that year and remain for a 12 -month period, although the schedule is at the discretion of Metropolitan's Board. Metropolitan's 2010 RUWMP forecasts that Metropolitan will be able to meet projected firm demands throughout the forecast period from 2015 to 2035. However, these projections do not mean that Metropolitan would not implement its WSAP during this period. City of Seal Beach ALC© { 1 ) 2010 Urban Water Management Plan 5 - IRN Section 5 Water Supplies Contingency Plan MWDOC To prepare for the potential allocation of imported water supplies from Metropolitan, MWDOC worked collaboratively with its 28 client agencies to develop its own Water Supply Allocation Plan (MWDOC WSAP), adopted January 2009, to allocate imported water supplies at the retail level. The MWDOC WSAP lays out the essential components of how MWDOC will determine and implement each client agency's allocation during a time of shortage. The MWDOC WSAP uses a similar method and approach, when reasonable, as that of the Metropolitan's WSAP. However, MWDOC's plan remains flexible to use an alternative approach when Metropolitan's method produces a significant unintended result for the client agencies. The MWDOC WSAP model follows five (5) basic steps to determine a retail agency's imported supply allocation. Step 1: Determine Baseline Information — The first step in calculating a water supply allocation is to estimate water supply and demand using a historical based period with established water supply and delivery data. The base period for each of the different categories of demand and supply is calculated using data from the last three non - shortage years — calendar years, 2004, 2005, and 2006. Step 2: Establish Allocation Year Information — In this step, the model adjusts for each member agency's water need in the allocation year. This is done by adjusting the base period estimates for increased retail water demand based on growth and changes in local supplies. Step 3: Calculate Initial Minimum Allocation Based on Metropolitan's Declared Shortage Level — This step sets the initial water supply allocation for each client agency. After a regional shortage level is established, MWDOC will calculate the initial allocation as a percentage of adjusted Base Period Imported water needs within the model for each client agency. Step 4: Apply Allocation Adjustments and Credits in the Areas of Retail Impacts, Conservation, and the Interim Agriculture Water Program — In this step, the model assigns additional water to address disparate impacts at the retail level caused by an across - the -board cut of imported supplies. It also applies a conservation credit given to those agencies that have achieved additional water savings at the retail level as a result of successful implementation of water conservation devices, programs and rate structures. Step 5: Sum Total Allocations and Determine Retail Reliability — This is the final step in calculating a retail agency's total allocation for imported supplies. The model sums an agency's total imported allocation with all of the adjustments and credits and then calculates each agency's retail reliability compared to its Allocation Year Retail Demand. City of Seal Beach ,,u_w IRNI 2010 Urban Water Management t Plan 5 - Section 5 Water Supplies Contingency Plan The MWDOC WSAP includes additional measures for plan implementation, including the following: o Appeal Process — An appeals process to provide client agencies the opportunity to request a change to their allocation based on new or corrected information. MWDOC anticipates that under most circumstances, a client agency's appeal will be the basis for an appeal to Metropolitan by MWDOC. o Melded Penalty Rate Structure — At the end of the allocation year, MWDOC would only charge a penalty to each client agency that exceeded their allocation if MWDOC exceeds its total allocation and is required to pay a penalty to Metropolitan. Metropolitan enforces allocations to member agencies through a tiered penalty rate structure: penalty rates to a member agency that exceeds its total annual allocation at the end of the twelve -month allocation period, according to a specified rate structure. MWDOC's penalty would be assessed according to the client agency's prorated share (acre -feet over usage) of MWDOC penalty amount with Metropolitan. Penalty funds collected by Metropolitan will be invested in water conservation and local resource development. o Tracking and Reporting Water Usage — MWDOC will provide each client agency with water use monthly reports that will compare each client agency's current cumulative retail usage to their allocation baseline. MWDOC will also provide quarterly reports on it cumulative retail usage versus its allocation baseline. o Timeline and Option to Revisit the Plan — The allocation period will cover 12 consecutive months and the Regional Shortage Level will be set for the entire allocation period. MWDOC only anticipates calling for allocation when Metropolitan declares a shortage; and no later than 30 days from Metropolitan's declaration will MWDOC announce allocation to its client agencies. Due to the complexity of calculating allocations and the potential for unforeseen circumstances that may occur during an allocation year, after one year of implementation, MWDOC staff and client agencies have the opportunity to make recommendations to the MWDOC Board that will improve the method, calculation, and approach of the MWDOC WSAP. City of Seal Beach The City Council adopted Water Conservation Ordinance No. 1586 on June 8, 2009, which established a staged water conservation program that will encourage reduced water consumption within the City through conservation, enable effective water supply planning, assure reasonable and beneficial use of water, prevent waste of water, and maximize the efficient use of water within the City. Along with permanent water conservation requirements, the City's Water Conservation Program consists of the following four stages found in Table 5 -1 to respond to a reduction in potable water ,���?�e; C ity of Seal Beach MALE() 2010 Urban Water Management Plan 5 - 4 IR ,.'

The City Council declares a water shortage emergency and notifies its residents and businesses that a 3 significant reduction in consumer demand is necessary to maintain sufficient water supplies for public health and safety. 5.3. Three -Year Minimum Water Supply Metropolitan does not provide annual estimates of the minimum supplies available to its member agencies. As such, Metropolitan member agencies must develop their own estimates for the purposes of meeting the requirements of the Act. Section 135 of the Metropolitan Water District Act declares that a member agency has the right to invoke its "preferential right" to water, which grants each member agency a preferential right to purchase a percentage of Metropolitan's available supplies based on specified, cumulative financial contributions to Metropolitan. Each year, Metropolitan calculates and distributes each member agency's percentage of preferential rights. However, since Metropolitan's creation in 1927, no member agency has ever invoked these rights as a means of acquiring limited supplies from Metropolitan. O City of Seal Beach 1 I_ACC0 2010 Urban Water Management Plan 5 - Section 5 Water Supplies Contingency Plan As an alternative to preferential rights, Metropolitan adopted the Water Shortage Allocation Plan (WSAP) in February 2008. Under the WSAP, member agencies are allowed to purchase a specified level of supplies without the imposition of penalty rates. The WSAP uses a combination of estimated total retail demands and historical local supply production within the member agency service area to estimate the firm demands on Metropolitan from each member agency in a given year. Based on a number of factors, including storage and supply conditions, Metropolitan then determines whether it has the ability to meet these firm demands or will need to allocate its limited supplies among its member agencies. Thus, implicit in Metropolitan's decision not to implement an allocation of its supplies is that at a minimum Metropolitan will be able to meet the firm demands identified for each of the member agencies. In order to estimate the minimum available supplies from Metropolitan for the period 2011 -2013, an analysis was performed to assess the likelihood that Metropolitan would re- implement mandatory water use restrictions in the event of a 1990 -92 hydrologic conditions over this period. Specific water management actions during times of water shortage are governed by Metropolitan's Water Shortage and Drought Management Plan (WSDM Plan). Adopted by the Metropolitan Board in 1999, the WSDM Plan provides a general framework for potential storage actions during shortages, but recognizes that storage withdrawals are not isolated actions but part of a set of resource management actions along with water transfers and conservation. As such, there is no specific criterion for which water management actions are to be taken at specific levels of storage. The implementation of mandatory restrictions is solely at the discretion of the Metropolitan Board and there are no set criteria that require the Board to implement restrictions. Given these conditions, the analysis relies upon a review of recent water operations and transactions that Metropolitan has implemented during recent drought. The first step in the analysis was a review of projected SWP allocations to Metropolitan, based on historical hydrologies. As with the recent drought, potential impacts to SWP supplies from further drought and the recently implemented biological opinions are anticipated to be the biggest challenges facing Metropolitan in the coming three years. A review of projected SWP allocations from the DWR's State Water Project Delivery Reliability Report 2009 (2009 SWP Reliability Report) was made to estimate a range of conservative supply assumptions regarding the availability of SWP supplies. The 2009 SWP Reliability Report provides estimates of the current (2009) and future (2029) SWP delivery reliability and incorporates regulatory requirements for SWP and CVP operations in accordance with USFWS and NMFS biological opinions. Estimates of future reliability also reflect potential impacts of climate change and sea level rise. The analysis assumes a maximum SWP allocation available to Metropolitan of 2,011,500 AF and a Metropolitan storage level of 1,700,000 AF at 2010 year -end. The analysis also rip" City of Seal Beach Urban Water Management Plan 5 - 4t;� N t Section 5 Water Supplies Contingency Plan assumes a stable water supply from the Colorado River in the amount of 1,150,000 AF through 2015. Although the Colorado River watershed has also experienced drought in recent years, Metropolitan has implemented a number of supply programs that should ensure that supplies from this source are relatively steady for the next three years. Based on estimated "firm" demands on Metropolitan of 2.12 MAF, the annual surplus or deficit was calculated for each year of the three -year period. A review of recent Metropolitan water management actions under shortage conditions was then undertaken to estimate the level of storage withdrawals and water transfers that Metropolitan may exercise under the 1990 -92 hydrologic conditions were identified. For this analysis, it was assumed that, if Metropolitan storage levels were greater than 2 MAF at the beginning of any year, Metropolitan would be willing to take up to 600 TAF out of storage in that year. Where Metropolitan storage supplies were between 1.2 MAF and 2 MAF at the beginning of the year, it was assumed that Metropolitan would be willing to take up to 400 TAF in that year. At storage levels below 1.2 MAF, it was assumed that Metropolitan would take up to 200 TAF in a given year. It was also assumed that Metropolitan would be willing to purchase up to 300 TAF of water transfer in any given year. For years where demands still exceeded supplies after accounting for storage withdrawals, transfer purchases were estimated and compared against the 300 TAF limit.

Given the assumed absence of mandatory restrictions, the estimated minimum imported water supplies available to MWDOC from Metropolitan is assumed to be equal to Metropolitan's estimate of demand for firm supplies for MWDOC, which Metropolitan uses when considering whether to impose mandatory restrictions. Thus, the estimate of the minimum imported supplies available to MWDOC is 261,577 AF " Metropolitan 2010/11 Water Shortage Allocation Plan model (March 2011) , co, ; K` City of Seal Beach IRN iF 201 Urban Water Management Plan 5 - I r Section 5 Water Supplies Contingency Plan MWDOC also has also adopted a shortage allocation plan and accompanying allocation model that estimates firm demands on MWDOC. Assuming MWDOC would not be imposing mandatory restrictions if Metropolitan is not, the estimate of firms demands in MWDOC's latest allocation model has been used to estimate the minimum imported supplies available to each of MWDOC's customer agencies for 2011 -13. Thus, the estimate of the minimum imported supplies available to the City is 4,313 AF 12. As captured in its 2010 RUWMP, Metropolitan believes that the water supply and demand management actions it is undertaking will increase its reliability throughout the 25 -year period addressed in its plan. Thus for purposes of this estimate, it is assumed that Metropolitan and MWDOC will be able to maintain the identified supply amounts throughout the three -year period. Metropolitan projects reliability for full service demands through the year 2035. Additionally, through a variety of groundwater reliability programs conducted by OCWD and participated in by the City, local supplies are projected to be maintained at demand levels. Based on the MWDOC Water Supply Allocation Plan, the City is expected to fully meet demands for the next three years assuming Metropolitan and MWDOC are not in shortage, a Basin Production Percentage of 62% for Local Supplies and zero allocations are imposed for Imported Supplies. The Three Year Estimated Minimum Water Supply is listed in Table 5 -3.

Catastrophic Supply Interruption Given the great distances that imported supplies travel to reach Orange County, the region is vulnerable to interruptions along hundreds of miles aqueducts, pipelines and other facilities associated with delivering the supplies to the region. Additionally, this water is distributed to customers through an intricate network of pipes and water mains that are susceptible to damage from earthquakes and other disasters. 12 MWDOC Water Shortage Allocation model (August 2010) �} City of Seal Beach R 2010 Urban Water Management Plan 5 -8 Section 5 Water Supplies Contingency Plan 5.4.1. Metropolitan Metropolitan has comprehensive plans for stages of actions it would undertake to address a catastrophic interruption in water supplies through its WSDM and WSAP Plans. Metropolitan also developed an Emergency Storage Requirement to mitigate against potential interruption in water supplies resulting from catastrophic occurrences within the southern California region, including seismic events along the San Andreas Fault. In addition, Metropolitan is working with the State to implement a comprehensive improvement plan to address catastrophic occurrences that could occur outside of the Southern California region, such as a maximum probable seismic event in the Delta that would cause levee failure and disruption of SWP deliveries. For greater detail on Metropolitan's planned responses to catastrophic interruption, please refer to Metropolitan's RUWMP. 5.4.2. Water Emergency Response of Orange County In 1983, the Orange County water community identified a need to develop a plan on how agencies would respond effectively to disasters impacting the regional water distribution system. The collective efforts of these agencies resulted in the formation of the Water Emergency Response Organization of Orange County (WEROC) to coordinate emergency response on behalf of all Orange County water and wastewater agencies, develop an emergency plan to respond to disasters, and conduct disaster training exercises for the Orange County water community. WEROC was established with the creation of an indemnification agreement between its member agencies to protect each other against civil liabilities and to facilitate the exchange of resources. WEROC is unique in its ability to provide a single point of contact for representation of all water and wastewater utilities in Orange County during a disaster. This representation is to the county, state, and federal disaster coordination agencies. Within the Orange County Operational Area, WEROC is the recognized contact for emergency response for the water community. 5.4.3. City of Seal Beach Water Shortage Emergency Response In 1991, in accordance with the requirements of Assembly Bill IIX, the City Water, and Emergency Services Departments developed a comprehensive water shortage contingency plan, which was incorporated into the City's Emergency Response Plan in early 1992. The City's plan is consistent with provisions in the County's Emergency Response Plan. Both plans contain procedures for the distribution of potable water in a disaster. These procedures are consistent with guidelines prepared by the California State Office of Emergency Services. The City recognizes the importance of the DMMs in reducing water demand and will strive to implement the programs within the constraints of small staff and resources. The City of Seal Beach ! 1vLALCOL�1 I'.IRNIt �< 2010 Urban Water Management Plan 5 - Section 5 Water Supplies Contingency Plan City would call media attention to the water supply situation during a shortage and would step up public water education programs, encourage property owners to apply for a landscape and interior water use survey and continue to advertise the importance of customers to install ULF plumbing fixtures. During declared shortages, or when a shortage declaration appears imminent, the Public Works Director, who serves as the authorized representative, activates a City water shortage response plan. During a declared water shortage, the City will accept applications for new building permits but will not issue permits until the shortage declaration is rescinded. Supplemental Water Supplies To offset future potential water shortages due to drought or disaster, the City is considering the following supplemental water supplies. ® Water Transfers - The City is dependent upon MWDOC and Metropolitan for water transfers, as its small demand cannot feasibly implant such a plan. O Long Term Additional Water Supply Options - To meet future long -term water demand beyond 2035, the City is relying on MWDOC, OCWD, and Metropolitan.

Impacts to Revenue The actions described above to address a range of water shortage conditions have the potential to impact the City's revenues and expenditures. To assess these impacts, the City calculated the revenue impacts resulting from a 10 %, 25% and 50% reduction in sales as compared to a base year that was based on an estimate of normal year baseline. Other factors incorporated into the analysis included water losses, pricing structure and avoided costs. The results of this analysis are shown below in Table 5 -8.

Agency Coordination The City does not own or operate wastewater treatment facilities and sends all collected wastewater to OCSD for treatment and disposal. The City relies on the Orange County Groundwater Basin for the majority of its water supply. As manager of the Basin, OCWD strives to maintain and increase the reliability of the Basin by increasing recycled water usage to replace dependency on groundwater. To further this goal, OCWD and OCSD have jointly constructed two water recycling projects, described below: OCWD Green Acres Project The Green Acres Project (GAP) is a water recycling effort that provides recycled water for landscape irrigation at parks, schools and golf courses as well as for industrial uses, such as carpet dyeing. GAP provides an alternate source of water to the cities of Fountain Valley, Huntington Beach, Newport Beach, Santa Ana, and Mesa Consolidated Water District. Current water users include Mile Square Park in Fountain Valley, Costa Mesa Golf Course, Home Ranch bean field and Chroma Systems carpet dyeing. Due to a growing demand for water in Orange County, it is sensible that recycled water be used whenever possible for irrigation and industrial uses to supplement groundwater. The use of GAP water will diminish to approximately 3 MGD upon completion of OCSD's P1 -102 (Fountain Valley Wastewater Secondary Treatment Expansion) project in the fall of 2011. OCWD Groundwater Replenishment System The Groundwater Replenishment System (GWRS), which has been operational since January 2008, takes highly treated sewer water and purifies it to levels that meet state and federal drinking water standards. It uses a three -step process that includes reverse osmosis, microfiltration, and ultraviolet light and hydrogen peroxide advanced oxidation treatment. The treated water is then injected into the seawater barrier to help prevent seawater intrusion into the groundwater basin and is percolated into deep aquifers where it eventually becomes part of Orange County's drinking water supply. The design and construction of the GWRS was a project jointly- funded by OCWD and OCSD. These two public agencies have worked together for more than 30 years. They are leading the way in water recycling and providing a locally - controlled, drought -proof and City of Seal Beach ,. ALCO 2010 Urban Water Management Plan 6 - Section 6 Recycled Water reliable supply of high - quality water in an environmentally sensitive and economical manner. The first step, Microfiltration (MF), is a separation process that uses polypropylene hollow fibers, similar to straws, with tiny holes in the sides that are 0.2 micron in diameter. By drawing water through the holes into the center of the fibers, suspended solids, protozoa, bacteria and some viruses are filtered out of the water. In the second step, Reverse osmosis (RO), membranes are made of semi- permeable polyamide polymer (plastic). During the RO process, water is forced through the molecular structure of the membranes under high pressure, removing dissolved chemicals, viruses and pharmaceuticals in the water. The end result is near- distilled- quality water so pure that minerals have to be added back in to stabilize the water. RO has been successfully used by OCWD since the mid -1970s to purify highly- treated wastewater for its seawater intrusion barrier at its Water Factory 21 (WF -21) from 1975- 2004. In the third step, water is exposed to high - intensity ultraviolet (UV) light with hydrogen peroxide (H202) to disinfect and destroy any trace organic compounds that may have passed through the reverse osmosis membranes. Examples of these trace organic compounds are N- Nitrosodimethylamine (NDMA) and 1 -4 Dioxane, which have to be removed to the parts- per - trillion level. UV with H202 is an effective disinfection/advanced oxidation process that keeps these compounds from reaching drinking water supplies. The GWRS has a current production capacity of 70 MGD, and a total production of 23.5 billion gallons per year. Once the water has been treated with the three -step process at the GWRS as described above, approximately 35 MGD of GWRS water is pumped into injection wells where it serves as a seawater intrusion barrier. Another 35 MGD is pumped to recharge basins in the City of Anaheim, where GWRS water filters through sand and gravel to replenish the deep aquifers of north and central Orange County's groundwater basin. At this time, OCWD has designed Phase 2 of the expansion, which will recycle approximately another 28 MGD of effluent. Investments beyond Phase 2 have not been approved by OCWD and would require further review before proceeding. If the further envisioned phase of the project is approved and developed, it is projected that up to 118 MGD of water will be produced.

Potential Recycled Water Uses While the City recognizes the potential uses of recycled water in its community, such as landscape irrigation, parks, industrial and other uses, the OCWD does not have the recycled water infrastructure to support the use of recycled water. The cost - effectiveness analyses that have been conducted throughout the years regarding recycled water infrastructure have not shown to be beneficial at this time. Therefore, the City supports, encourages and contributes to the continued development of recycled water and potential uses throughout the region through the GWRS. At this time, the City does not have any potential and projected uses for recycled water. Table 6 -4 compares the recycled water use projections from the City's 2005 UWMP with actual 2010 recycled water use.

Indirect Potable Reuse The City benefits indirectly from the replenishment of the Orange County groundwater basin using GWRS water that meets state and federal drinking water standards for potable reuse. 6.5. Optimization Plan Because the City is not using recycled water at this time, it is not practicable to provide a recycled water optimization plan. The City has positioned itself to receive recycled water if it becomes available to serve some of the large development areas. - City of Seal Beach ALC�(�1 2010 Urban Water Management Plan 6 - 4 r IRNI • Section 6 Recycled Water In Orange County, the majority of recycled water is used for irrigating golf courses, parks, schools, business and communal landscaping. However, future recycled water use can increase by requiring dual piping in new developments, retrofitting existing landscaped areas and constructing recycled water pumping stations and transmission mains to reach areas far from the treatment plants. Gains in implementing some of these projects have been made throughout the county; however, the additional costs, large energy requirements and facilities to create such projects are very expensive to pursue. To determine if a recycled water project is cost - effective, cost/benefit analyses must be conducted for each potential project. This brings about the discussion on technical and economic feasibility of a recycled water project requiring a relative comparison to alternative water supply options. Analyses indicate that capital costs of water recycling in the City exceed the cost of purchasing additional imported water from Metropolitan. The City will continue to conduct cost/benefit analyses for recycled various water projects, and seek creative solutions and a balance to recycled water use, in coordination with MWDOC, OCWD, Metropolitan and other cooperative agencies. These include solutions for funding, regulatory requirements, institutional arrangements and public acceptance.

Water Management Tools Resource optimization such as desalination to minimize the needs for imported water is led by the regional agencies in collaboration with local agencies. With the eventual replacement of older wells with new more efficient wells, increasing the capacity of existing booster stations, and continued efforts in reducing water waste, the City can meet projected demands with existing facilities and distribution system. 7.2. Transfer or Exchange Opportunities Metropolitan currently has a tiered unbundled rate structure. Tier 2 of this rate structure increases the cost of supply to a member agency in order to provide a price signal that encourages development of alternative supply sources. One alternative source of supply may be a transfer or exchange of water with a different agency. MWDOC will continue to help its member agencies in developing these opportunities and ensuring their success. In fulfilling this role, MWDOC will look to help its member agencies navigate the operational and administrative issues of wheeling water through the Metropolitan water distribution system. The City relies on the efforts of Metropolitan as well as MWDOC to pursue transfer or exchange opportunities. At this time, the City is not currently involved in any transfer or exchange opportunities. 7.3. Planned Water Supply Projects and Programs At this time, the City does not have any planned water supply projects or programs. 7.4. Desalination Opportunities Until recently, seawater desalination had been considered uneconomical to be included in the water supply mix. However, recent breakthroughs in membrane technology and plant sitting strategies have helped reduce desalination costs, warranting consideration among • alternative resource options. MWDOC has been in the process of studying the feasibility of ocean desalination on behalf of its member agencies, but implementation of large -scale seawater desalination plants faces considerable challenges. These challenges include high capital and operation costs for power and membrane replacement, availability of funding measures and grants, City of Seal Beach '°IRM 2010 Urban Water Management Plan 7 -1 Section 7 Future Water Supply Projects and Programs addressing environmental issues and addressing the requirements of permitting organizations such as the Coastal Commission. These issues require additional research and investigation. MWDOC is reviewing and assessing treatment technologies, pretreatment alternatives, and brine disposal issues. Identifying and evaluating resource issues such as permitting and the regulatory approvals (including CEQA) associated with the delivery of desalinated seawater to regional and local distribution systems also present considerable challenges. In Orange County, there are three proposed ocean desalination projects that could serve MWDOC, including one specifically that may benefit the City. These are the Huntington Beach Seawater Desalination Project, the South Orange Coastal Desalination Project, and Camp Pendleton Seawater Desalination Project.

Ocean Water Huntington Beach Seawater Desalination Project — Poseidon Resources LLC (Poseidon), a private company, has proposed development of the Huntington Beach Seawater Desalination Project to be located adjacent to the AES Generation Power Plant in the City of Huntington Beach along Pacific Coast Highway and Newland Street. The proposed project would produce up to 50 MGD (56,000 AFY) of drinking water and will distribute water to coastal and south Orange County to provide approximately 8% of Orange County's water supply needs. The project supplies would be distributed to participating agencies through a combination of (1) direct deliveries through facilities including the East Orange County Feeder #2 (EOCF #2), the City of Huntington Beach's distribution system, and the West Orange County Water Board Feeder #2 (WOCWBF #2), and (2) water supply exchanges with agencies with no direct connection to facilities associated with the Project.

On May 24, 2010, the City signed a non - binding LOI for 0.8 MGD (850 AFY) of Project supplies. The Project has received specific approvals from the Huntington Beach City Council, including the Coastal Development Permit, Tentative Parcel Map, Subsequent Environmental Impact Report and Conditional Use Permit, which collectively provided for the long -term operation of the desalination facility. In addition to final agreements with the participating agencies, the Project still needs approvals from the State Lands Commission and the California Coastal Commission before Poseidon can commence construction of the desalination facility in Huntington Beach. A public hearing on the Project before the State Lands Commission is expected as early as this October. If project receives all required permits by 2011, it could be producing drinking water for Orange County by as soon as 2013. South Orange Coastal Desalination Project — MWDOC is proposing a desalination project in joint with Laguna Beach County Water District, Moulton Niguel Water District, City of San Clemente, City of San Juan Capistrano, South Coast Water District, and Metropolitan. The project is to be located adjacent to the San Juan Creek in Dana Point just east of the transition road from PCH to the I -5. The project will provide 15 MGD (16,000 AFY) of drinking water and will provide up to 30% of its potable water supply to the participating agencies. Phase 1 consists of drilling 4 test borings and installing monitoring wells. Phase 2 consists of drilling, constructing and pumping a test slant well. Phase 3 consists of constructing a Pilot Test Facility to collect and assess water quality. Phases 1 and 2 have been completed and Phase 3 commenced in June 2010 and will last 18 months. If pumping results are favorable after testing, a full -scale project description and EIR will be developed. If EIR is adopted and necessary permits are approved, project could be operational by 2016. Camp Pendleton Seawater Desalination Project— San Diego County Water Authority (SDCWA) is proposing a desalination project in joint with Metropolitan to be located at Camp Pendleton Marine Corps Base adjacent to the Santa Margarita River. The initial project would be a 50 or 100 MGD plant with expansions in 50 MGD increments up to a max of 150 MGD making this the largest proposed desalination plant in the US. The project is currently in the study feasibility stage and is conducting geological surveys to study the effect on ocean life and examining routes to bring desalination to SDCWA's delivery system. MWDOC and south Orange County agencies are maintaining a potential interest in the project, but at this time is only doing some limited fact finding and monitoring of the project.

Overview Recognizing that close coordination among other relevant public agencies is the key to the success of its UWMP, the City worked closely with other entities such as MWDOC to develop and update this planning document. The City also encouraged public involvement through a holding of a public hearing to learn and ask questions about their water supply. This section provides the information required in Article 3 of the Water Code related to adoption and implementation of the UWMP. Table 8 -1 summarizes external coordination and outreach activities carried out by the City and their corresponding dates. The UWMP checklist to confirm compliance with the Water Code is provided in Appendix A. Table 8 -1: External Coordination and Outreach External Coordination and Outreach Date Reference Encouraged public involvement (Public Hearing) May 30, 2011 & Appendix F June 6, 2011 Notified city or county within supplier's service area that water supplier is preparing an updated Appendix E UWMP (at least 60 days prior to public hearing) Held public hearing June 13, 2011 Appendix F Adopted UWMP Appendix G Submitted UWMP to DWR (no later than 30 days after adoption) Submitted UWMP to the California State Library and city or county within the supplier's service area (no later than 30 days after adoption) Made UWMP available for public review (no later than 30 days after filing with DWR) This UWMP was adopted by the City Council on MONTH DAY, YEAR.

The City sent a Letter of Notification to the County of Orange on DATE that it is in the process of preparing an updated UWMP (Appendix E). 8.2. Public Participation The City has encouraged community participation in development of its urban water management planning efforts since the first plan was prepared in 1985. Public meetings were held prior to adoption of the previous plans. For this update to the UWMP, a public meeting is scheduled to be held to review and receive comments on the draft plan before the City Council approval. The meeting was held on June 13, 2011 Notices of public meetings were posted in the City Hall. Legal public notices for the meeting was published in the local newspaper and posted at City facilities. Copies of the draft plan were available at the City Hall and the Library. A copy of the published Notice of Public Hearing is included in Appendix F. 8.3. Agency Coordination All of the City's water supply planning relates to the policies, rules, and regulations of its regional and local water providers. The City is dependent on imported water from Metropolitan through MWDOC, its regional wholesaler. The City is also dependent on groundwater from OCWD, the agency which manages the Orange County Basin. As such, the City involved these water providers in the development of its 2010 UWMP at various levels of contribution as summarized in Table 8 -2.

CO N M as .0 Appendix B Orange County Water District Groundwater Management Plan 2009 Update Appendix C Calculation of Dry Year Demands Demand "Bump" Factors for 2010 UWMP Description of Methodology Water agencies must develop estimates of the impacts of single dry years (Single -Dry) and multiple consecutive dry years (Multiple -Dry) on both supplies and demands in future years. In these cases, demands increase somewhat above the normal or average level. The increase can be expressed as a percent "bump" up from the normal level. For example, if dry year demand was 105 percent of normal, this would be a 5% "bump ". As the methodology to estimate the Single -Dry and Multiple -Dry "bumps" was developed, several issues needed to be decided, as follows: 1. The methodology used existing data from MWDOC records for each agency, to allow the estimates to reflect the characteristics and differences of demands relative to the makeup of each retail entity. The overall MWDOC estimate was developed from a weighted sum of all of OC's agencies. 2. Total potable demands, including agricultural demands, were used to derive the "bumps" because Orange County agencies have opted to have water that is used for agricultural uses be considered as full service demands. Non - potable demands are included; these demands will be met with non - potable supplies. 3. The methodology focused on per- capita usage (in units of AF /capita) because this removes the influence of growth from the analysis. Overall population growth in Orange County has been about 1% per year over the past two decades, creating about a 20% increase in demand over two decades. Some of the agencies have had even higher growth. • 4. The period that was used for the analysis was limited to FY 1992 -93 thru FY 2008 -09 because fiscal years 1991- 92 and 2009 -10 were years of extraordinary conservation -- pricing disincentives for using over the allocated amounts were implemented in order to curtail demands -- and so these years were not considered. The Orange County total per- capita water usage in the period FY 1992 -93 thru FY 2008 -09 is plotted in Figure 1. Per - capita water use in Orange County has been on a decreasing trend in recent years as shown by the trend line in Figure 1. The downward trend is likely due to water use efficiency efforts, principally the plumbing codes since 1992 that have required low -flush toilets in all new construction and prohibited the sale of high -flush toilets for replacement purposes. Because of this drop in per- capita usage over time, the more recent data is a better predictor of future usage than the earlier data. Therefore, we narrowed the focus to the period FY 2001 -02 thru FY 2008 -09. 5. Single -Dry "Bump" Methodology: Per - capita usage for each participant agency from FY 2001 -02 thru FY 2008- 09 is shown in Table 1. The Single -Dry Bump for each agency was derived using the highest per- capita usage in the period, divided by average per- capita usage for that period. Because of suspect data for Fountain Valley and Santa Ana, the highest year data was eliminated and the second - highest usage in the period was used (when data was suspect, it was also removed from the average for the agency). The resulting Single -Dry "bumps" are shown in Table 2. The OC- average Single -Dry "bump" came to 6.6% 6. Multiple -Dry "Bump" Methodology: DWR guidelines recommend that "multiple" years is three years. There are various methods that can be used to derive demand "bumps" for those three years. The same "bump" can be used for all three years, or different "bumps" can be assumed for each of the three years. A pattern can be selected based on historical demand data or on historical water supply data or on another basis. MWDOC selected a Multiple -Dry Bump as the same as the Single -Dry Bump for each agency. This means having three highest- demand years in a row. This is conservative because it would be extremely unlikely for three driest years to occur in a row. However, it should be noted that future demand in any particular year depends on other factors in addition to rainfall, such as the economic situation, and cloudiness, windiness, etc. The OC- average Multiple -Dry "bump" came to 6.6 %.

Linda Devine City Clerk Ordinance No. 1588 ORDINANCE NUMBER 1588 AN ORDINANCE OF THE CITY OF SEAL BEACH AMENDING THE SEAL BEACH MUNICIPAL CODE BY ADDING THERETO CHAPTER 9.70 REGARDING WATER EFFICIENT LANDSCAPING THE SEAL BEACH CITY COUNCIL DOES ORDAIN AS FOLLOWS: Section 1. The Seal Beach Municipal Code is hereby amended by adding • Chapter 9.70 thereto to read as follows: "Chapter 9.70: Water Efficient Landscaping 9.70.005 Purpose A. The State Legislature has found that: 1. the waters of the State are of limited supply and are subject to ever increasing demands; 2. the continuation of California's economic prosperity is dependent on the availability of adequate supplies of water for future uses; 3. it is the policy of the State to promote the conservation and efficient use of water and to prevent the waste of this valuable resource; 4. landscapes are essential to the quality of life in California by providing areas for active and passive recreation and as an enhancement to the environment by cleaning air and water, preventing erosion, offering fire protection, and replacing ecosystems lost to development; 5. landscape design, installation, maintenance, and management can and should be water efficient; and 6. Article X, Section 2 of the California Constitution specifies that the right to use water is limited to the amount reasonably required for the beneficial use to be served, and the right does not and shall not extend to waste or unreasonable method of use of water. B. The City hereby finds that: 1. Orange County has an established, large reclaimed water infrastructure system; • 2. Allocation -based and tiered water rate structures allow public agencies to document water use in landscapes; 3. Incentive -based water use efficiency programs have been actively implemented within Orange County since before 1991; 4. current local design practices in new landscapes typically achieve the State Model Water Efficient Landscape Ordinance water use goals; 5. all water services within the City are metered; 6. Orange County is a leader in researching and promoting the use of smart automatic irrigation controllers with more than 4,500 installations as of June 2009; Ordinance Number 1588 7. all new irrigation controllers sold after 2012 within Orange County will be smart controllers; 8. the average rainfall in Orange County is approximately 12 inches per year. 9. the City as the local water purveyor has implemented a tiered rate billing program and endorses water waste prohibitions for all existing metered landscaped areas throughout its service area, which includes a majority of the City of Seal Beach. 10. that this council has determined, based upon the written and oral testimony presented to it, that this Chapter is substantially equivalent to the model ordinance prepared by the State of California. C. Consistent with these findings, the purpose of this Chapter is to establish an alternative model acceptable under AB 1881 as being at least as effective as the State Model Water Efficient Landscape Ordinance in the context of conditions in the City in order to: 1. promote the benefits of consistent landscape ordinances with neighboring local and regional agencies; 2. promote the values and benefits of landscapes while recognizing the need to invest water and other resources as efficiently as possible; 3. establish a structure for planning, designing, installing, and maintaining and managing water efficient landscapes in new construction and rehabilitated projects; 4. establish provisions for water management practices and water waste prevention for existing landscapes; 5. use water efficiently without waste by setting a Maximum Applied Water Allowance as an upper limit for water use and reduce water use to the lowest practical amount; and 6. encourage the use of economic incentives that promote the efficient use of water, such as implementing a tiered -rate structure. 9.70.010 Applicability. A. All planting, irrigation, and landscape- related improvements required by this Chapter shall apply to the following landscape projects: 1. new landscape installations or landscape rehabilitation projects by public agencies or private non - residential developers, except for cemeteries, with a landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 2,500 square feet, and which are otherwise subject to a discretionary approval of a landscape plan, or which otherwise require a ministerial permit for a landscape or water feature; 2. new landscape installations or landscape rehabilitation projects by developers or property managers of single - family and multi - family residential projects or complexes with a landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 2,500 square feet, and which are otherwise subject to a discretionary approval of a landscape plan, or which otherwise require a ministerial permit for a landscape or water feature; PW - Ord #I588 - Water Efficient Landscape (item H).DOC Ordinance Number 1588 3. new landscape installation projects by individual homeowners on single - family or multi - family residential lots with a total project landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 5,000 square feet, and which are otherwise subject to a discretionary approval of a landscape plan, or which otherwise require a ministerial permit for a landscape or water feature; 4. sections 2.2, 2.8 and 2.9 of the Guidelines shall apply to new landscape installations or landscape rehabilitation projects at cemeteries. B. Section 3(b) of the Landscape Water Use Standards of this Chapter shall apply to: 1. all landscaped areas installed after January 1, 2010 to which Section 1.1(a) is applicable. • C. This Chapter does not apply to: 1. registered local, state, or federal historical sites; 2. ecological restoration projects that do not require a permanent irrigation system; 3. plant collections, as part of botanical gardens and arboretums open to the public. 9.70.015 Implementation Procedures • A. Prior to installation, a Landscape Documentation Package shall be submitted to the City for review and approval of all landscape projects subject to the provisions of this Chapter. Any Landscape Documentation Package submitted to the City shall comply with the provisions of the Guide lines. B. The Landscape Documentation Package shall include a certification by a professional appropriately licensed in the State of California stating that the landscape design and water use calculations have been prepared by or under the supervision of the licensed professional and are certified to be in compliance with the provisions of this Chapter and the Guidelines. 1. Landscape and irrigation plans shall be submitted to the City for review and approval with appropriate water use calculations. Water use calculations shall be consistent with calculations contained in the Guidelines and shall be provided to the local water purveyor, under procedures determined by the City. 2. Verification of compliance of the landscape installation with the approved plans shall be obtained through a Certification of Completion in conjunction with a Certificate of Use and Occupancy or Permit Final process, as provided in the Guidelines. • 9.70.020 Landscape Water Use Standards A. For applicable landscape installation or rehabilitation projects subject to Section 1.1(a) of this Chapter, the Estimated Applied Water Use allowed for the landscaped area shall not exceed the MAWA calculated using an ET adjustment factor of 0.7, except for special landscaped areas where the MAWA is calculated using an ET adjustment factor of 1.0; or the design of the landscaped area shall otherwise be shown to be equivalently water - efficient in a manner acceptable to the City; as provided in the Guidelines. PW - Ord #1588 - Water Efficient Landscape (item H).DOC Ordinance Number 1588 B. Irrigation of all landscaped areas shall be conducted in a manner conforming to the rules and requirements, and shall be subject to penalties and incentives for water conservation and water waste prevention as determined and implemented by the local water purveyor or as mutually agreed by local water purveyor and the City. 9.70.025 Third Party. The City may enter into a contract with, a local agency or third party with lawful authority, to implement, administer, and /or enforce any of the provisions of the Chapter on behalf of the City. 9.70.030 Definitions. The following definitions are applicable to this [chapter /division /title]: 1. Applied water: the portion of water supplied by the irrigation system to the landscape. 2. Budget -based tiered -rate structure: tiered or block rates for irrigation accounts charged by the retail water agency in which the block definition for each customer is derived from lot size or irrigated area and the evapotranspiration requirements of landscaping. 3. Ecological restoration project: a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem. 4. Estimated Applied Water Use: the average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Guidelines. It is based on the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the relative irrigation efficiency of the irrigation system. 5. ET adjustment factor" or "ETAF: is equal to the plant factor divided by the irrigation efficiency factor for a landscape project, as described in the Guidelines. The ETAF is calculated in the context of local reference evapotranspiration, using site - specific plant factors and irrigation efficiency factors that influence the amount of water that needs to be applied to the specific landscaped area. A combined plant mix with a site -wide average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) = (0.5/0.71), which is the standard of water use efficiency generally required by this Chapter and the Guidelines, except that the ETAF for a special landscape area shall not exceed 1.0. 6. Guidelines: refers to the Guidelines for Implementation of the Water Efficient Landscape Ordinance, as adopted by the City, which describes procedures, calculations, and requirements for landscape projects subject to this Chapter. The Guidelines shall be adopted by resolution and may be amended from time to time. 7. Hardscapes: any durable material or feature (pervious and non - pervious) installed in or around a landscaped area, such as pavements or walls. Pools and other water features are considered part of the landscaped area and not considered hardscapes for purposes of this Chapter. 8. Homeowner installed landscape: any landscaping either installed by a private individual for a single family residence or installed by a licensed contractor hired by a homeowner. A homeowner, for purposes of this Chapter, is a person who occupies the dwelling he or she owns. This definition excludes speculative homes, which are not owner - occupied dwellings and which PW - Ord #1588 - Water Efficient Landscape (item H).DOC Ordinance Number 1588 are subject under this Chapter to the requirements applicable to developer - installed residential landscape projects. 9. Irrigation efficiency: the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum average irrigation efficiency for purposes of this Chapter is 0.71. Greater irrigation efficiency can be expected from well designed and maintained systems. 10. Landscaped area: all the planting areas, turf areas, and water features in a landscape design plan subject to the Maximum Applied Water Allowance and Estimated Applied Water Use calculations. The landscaped area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non - pervious hardscapes, and other non - irrigated areas designated for non - development (e.g., open spaces and existing native vegetation). 11. Landscape contractor: a person licensed by the State of California to construct, maintain, repair, install, or subcontract the development of landscape systems. 12. Landscape Documentation Package: the documents required to be provided to the City for review and approval of landscape design projects, as described in the Guidelines. 13. Landscape project: total area of landscape in a project, as provided in the definition of "landscaped area," meeting the requirements under Section 1.1 of this Chapter. 14. Local agency: a city or county, including a charter city or charter county, that is authorized by the City to implement, administer, and /or enforce any of the provisions of this Chapter on behalf of the City. The local agency may be responsible for the enforcement or delegation of enforcement of this Chapter including, but not limited to, design review, plan check, issuance of permits, and inspection of a landscape project. 15. Local water purveyor" means any entity, including a public agency, city, county, or private water company that provides retail water service. 16. Maximum Applied Water Allowance or MAWA: the upper limit of annual applied water for the established landscaped area as specified in Section 2.2 of the Guidelines. It is based upon the area's reference evapotranspiration, the ET Adjustment Factor, and the size of the landscaped area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water Allowance. 17. New construction: for the purposes of this Chapter, a new building with a landscape or other new landscape such as a park, playground, or greenbelt without an associated building. 18. Non - pervious: any surface or natural material that does not allow for the passage of water through the material and into the underlying soil. 19. Pervious: any surface or material that allows the passage of water through the material and into the underlying soil. 20. Permit: an authorizing document issued by local agencies for new construction or rehabilitated landscape. 21 Plant factor or plant water use factor: is a factor, when multiplied by ETo, that estimates the amount of water needed by plants. For PW - Ord #1588 - Water Efficient Landscape (item H).DOC Ordinance Number 1588 purposes of this Chapter, the plant factor range for low water use plants is 0 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6; and the plant factor range for high water use plants is 0.7 to 1.0. Plant factors cited in this Chapter are derived from the Department of Water Resources 2000 publication "Water Use Classification of Landscape Species." 22. Recycled water or reclaimed water: treated or recycled waste water of a quality suitable for non - potable uses such as landscape irrigation and water features. This water is not intended for human consumption. 23. Reference evapotranspiration or ETo: a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix A of the Guidelines, and is an estimate of the evapotranspiration of a large field of four -to seven -inch tall, cool- season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances. 24. Rehabilitated landscape: any re- landscaping project that meets the applicability criteria of Section 1.1(a), where the modified landscape area is greater than 2,500 square feet, is 50% of the total landscape area, and the modifications are planned to occur within one year. 25. Smart automatic irrigation controller: an automatic timing device used to remotely control valves that operate an irrigation system and which schedules irrigation events using either evapotranspiration (weather - based) or soil moisture data. 26. Special landscape area: an area of the landscape dedicated solely to edible plants such as orchards and vegetable gardens, areas irrigated with recycled water, water features using recycled water, and areas dedicated to active play such as parks, sports fields, golf courses, and where turf provides a playing surface. 27. Turf: a ground cover surface of mowed grass. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool- season grasses. Bermudagrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass, and Buffalo grass are warm - season grasses. 28. Valve: a device used to control the flow of water in an irrigation system. • 29. Water feature: a design element where open water performs an aesthetic or recreational function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools (where water is artificially supplied). The surface area of water features is included in the high water use hydrozone of the landscaped area. Constructed wetlands used for on- site wastewater treatment, habitat protection or storm water best management practices that are not irrigated and used solely for water treatment or storm water retention are not water features and, therefore, are not subject to the water budget calculation." Section 2. Exemption from California Environmental Quality Act. The City Council hereby determines that this Ordinance is exempt from review under the California Environmental Quality Act ( "CEQA ") (California Public Resources Code Section 21000 et seq.), because pursuant to State CEQA Regulation 15307 (14 Cal. Code Regs., § 15307), this Ordinance is covered by the CEQA Categorical Exemption for actions taken to assure the maintenance, restoration, enhancement, or protection of a natural resource where the regulatory process involves procedures for protection of the environment. The PW - Ord #1588 - Water Efficient Landscape (item H).DOC Option 4 — Other options Ordinance Number 1588 specific to thp.
