June 2016 ES-1 Executive Summary ES 1 Purpose and Organization Preparation of an Urban Water Management Plan (UWMP) is required by the California Department of Water Resources (DWR) for all urban water suppliers within the State of California. Urban water suppliers are defined as publicly or privately owned water suppliers that provide water for municipal purposes either directly or indirectly to more than 3,000 customers or supply more than 3,000 acre- feet (AF) of water annually. UWMPs must meet requirements established by the California Water Code (CWC) and the Urban Water Management Planning Act (Act). This report constitutes the 2015 Urban Water Management Plan (2015 UWMP) for Carlsbad Municipal Water District (CMWD), which must be adopted by CMWD’s Board of Directors and submitted to DWR by July 1, 2016. This 2015 UWMP satisfies the requirements of the CWC, the Act, and subsequent amendments. In addition to satisfying regulatory requirements, this report is a resource document that includes an analysis of long-term water supply and demand planning for CMWD’s service area. Table ES-1 includes a summary of each section of this 2015 UWMP.

CMWD serves the majority of the City of Carlsbad; Olivenhain Municipal Water District (OMWD) and Vallecitos Water District (VWD) serve the remaining southeastern portion. The service area is bordered by OMWD and the City of Encinitas to the south, VWD to the southeast, the City of Vista to the northeast, the City of Oceanside to the north, and the Pacific Ocean to the west. CMWD’s weather is characterized as a Mediterranean climate with mild temperatures year round. The mild climate is derived from the warm ocean water being pulled north from Mexico and from the subtropical, semi-desert locale. Resulting temperatures are, on average, 64 degrees in January and 75 degrees in August. CMWD’s service area receives an average of approximately 11 inches of precipitation annually, with most of the rainfall occurring in January and February. CMWD’s 2015 water supplies included purchased water and recycled water. Potable water demands are all currently met with water purchased from the San Diego County Water Authority (SDCWA), while recycled water is used for non-potable uses to offset potable water use. SDCWA is the regional wholesale water agency in San Diego County, and serves 24 member agencies, including CMWD. SDCWA’s supply mix includes Colorado River water, State Water Project (SWP) water, and desalinated seawater. SDCWA purchases its SWP and a portion of its Colorado River supplies from the Metropolitan Water District of Southern California (MWD). SDCWA also receives Colorado River water via transfers from Imperial Irrigation District (IID) and conservation savings from various canal lining projects. However, both of these imported sources (SWP and Colorado River) have become less reliable since the early 1990s as a result of significant droughts, water rights issues, and environmental restrictions. To help offset demands on these imported supplies, SDCWA purchases desalinated seawater from the Claude “Bud” Lewis Carlsbad Desalination Plant (Carlsbad Desalination Plant) and blends it into member agency supplies. Moving forward, CMWD plans to increase local supply reliability and offset demands for imported water by expanding its recycled water distribution system, increasing its purchases of desalinated seawater, building a direct connection to the desalinated pipeline, and exploring its groundwater rights. CMWD is a member of the North San Diego Water Reuse Coalition (NSDWRC), which consists of ten member June 2016 ES-3 2015 Urban Water Management Plan Executive Summary Carlsbad Municipal Water District Final agencies who are cooperatively implementing a regional recycled water system to maximize recycled water use and implement potable reuse. These projects will allow CMWD to expand beneficial reuse of local wastewater for non-drinking water purposes such as irrigation and industrial uses. CMWD may also pursue groundwater as a future supply source, and is currently exploring its groundwater rights. In addition, CMWD’s Board approved an agreement in April 2016 to purchase additional desalinated seawater, separate from the desalinated water received via SDCWA purchases, and to construct a direct connection to the desalinated seawater pipeline. Table ES-2 provides a summary of CMWD’s projected water supplies from 2020-2040. Note that future groundwater supplies are not included in this table because they have not yet been quantified.

The Carlsbad WRF is undergoing an expansion, resulting in the substantial increase in recycled water supply between 2015 and 2020. ES 3 CMWD’s Current and Projected Demands CMWD’s historical water demands have varied from year to year, which is mainly attributed to annual variations in weather and droughts. All urban water suppliers throughout California are mandated by the Water Conservation Act of 2009 (also referred to as SBx7-7) to reduce per capita potable water demands by 20% by the year 2020. For 2015, CMWD was required to have a per capita water use (measured in gallons per capita per day [gpcd]) of 233 gpcd. CMWD’s actual potable water demands for 2015 were 145 gpcd, which is well below the 2015 target. Reduced demands in CMWD’s service area are likely the result of ongoing conservation programs that have been implemented in response to the SBx7-7 legislation, along with enhanced conservation that is currently in effect in response to a multi-year drought. Table ES-3 shows the baselines and targets projected for CMWD for compliance with SBx7-7. As shown in the table, CMWD elected to use a 10-year baselines, from 1999 through 2008, inclusive. Table ES-3: SBx7-7 Baselines and Targets for CMWD Baseline Period Start Years End Years Average GPCD 2015 Target 2020 Target 10-15 year 1999 2008 259 233 207 CMWD’s demand projections anticipate a rebound effect (increased demands) when the drought subsides. However, CMWD also assumes ongoing conservation, and increased recycled water use, which will reduce potable water demands. The 2015 UWMP demand analysis demonstrates that with existing and anticipated conservation efforts, CMWD is on track to meet its 2020 gpcd target of 207 gpcd. Table ES-4 summarizes CMWD’s baseline demands, conservation, recycled water use, and overall potable demand projections for 2020-2040.

Increased recycled water use will offset projected potable demands. 5 Total Potable Water is the Projected Demands less Recycled Water Demand. Figure ES-1 shows historical and projected water use, by use sector. Recycled water is also shown to provide a comprehensive image of CMWD’s supply portfolio. Projected demands assume a normal hydrologic year, while 2015 demands are the third year of a multiple dry year period. Projected potable demands meet or exceed CMWD’s SBX7-7 target.

Consistent with SDCWA’s 2015, CMWD projects that demands will increase as weather gets hotter and drier during the single-dry year and multiple-dry year scenarios. Recycled water supplies and CWMD’s direct purchase of desalinated seawater would remain steady in all hydrologic scenarios because they are both drought-proof, local supplies. Changes in demands would necessitate changes to CMWD’s purchases of supplies from SDCWA. Because SDCWA and CMWD coordinated on their supply and demand projections, for all years that SDCWA projects reliability, CMWD assumes it will be able to purchase sufficient supplies to meet demands. In the event that SDCWA projects a supply shortfall, CMWD would implement extraordinary conservation measures or convert additional customers to recycled water to reduce potable water demands. CMWD’s water supply reliability analysis shows that with implementation of additional planned supplies (such as groundwater) and conservation measures, supplies will meet demands under all hydrologic scenarios. ES 5 Water Shortages and Demand Management CMWD has two ordinances in place to help manage demands during potential water shortages. Ordinance No. 44: Drought Response Plan and Water Conservation Program is CMWD’s Drought Ordinance, which establishes CMWD’s drought response levels and the conservation measures that are enacted for each level as it is declared. Each of these response levels enacts increasingly stringent water use reduction measures and potential penalties. In general, higher response levels incorporate all previous restrictions, and impose additional restrictions as described in the Drought Ordinance. Ordinance No. 46: Water Schedules is an amendment to CMWD’s Drought Ordinance, and revised Drought Response Levels 2 and 3 to allow for increased flexibility for CMWD in establishing water limits during these drought levels. CWMD also engages in various public outreach and education campaigns and conservation programs to improve water use efficiency and awareness. Staff attend community events and manage UWMPs and the Water Conservation Act of 2009: Conservation requirements for the UWMP are based on the Water Conservation Act of 2009 (SBX7-7). This act mandates a 20% reduction in water use from average (based on 10-15 year baseline), measured in GPCD (gallons per capita per day, based on gross water use), by 2020, with an interim target of 10% reduction by 2015. For more information, refer to: http://www.water.ca.gov/urbanwatermanagement/uwmp201 5.cfm 2015/2016 Emergency Regulations: Executive Order B-29-15 (April 2015; extended March 2016) imposed temporary mandatory conservation aimed at achieving 25% reduction statewide from 2013 levels during the current multi-year drought. Each water purveyor was assigned a conservation target by the state, measured in R-GCPD (residential gallons per capita per day, based on residential water use). CMWD’s initial conservation target was 28%, but was reduced to 20% due to regional supply development. For more information, refer to: http://www.waterboards.ca.gov/water_issues/programs/cons ervation_portal/emergency_regulation.shtml 2016 Extended Emergency Regulations: In May 2016, the SWRCP adopted new emergency regulations (applies June 2016 – January 2017) that would allow water purveyors to identify their own temporary conservation targets based on their ability to meet demands during continuation of multiple dry year conditions into 2017, 2018, and 2019.

Water conservation resources are provided to customers at CMWD’s Water Savings Tips website (http://www.carlsbadca.gov/services/depts/pw/utils/water/tips.asp), which provides links to water use calculators, WaterSmart landscaping guides, videos on water conservation, and information on water conservation and efficiency rebates, among others. June 2016 1-1 Introduction and Overview This 2015 Urban Water Management Plan (2015 UWMP) addresses the Carlsbad Municipal Water District (CMWD) and includes descriptions of CMWD’s water supply sources, projected water demands, and supply reliability. The 2015 UWMP presents a comparison of projected water supplies to water demands during normal, single-dry, and multiple-dry years. This chapter provides an introduction to the purpose of the 2015 UWMP and an overview of the Urban Water Management Planning Act. 1.1 Background and Purpose Water planning has become increasingly critical as California endures the ongoing drought and prepares for expected long-term climate changes. Prior to the adoption of the Urban Water Management Planning Act (the Act), water suppliers were not required to conduct long-term water resources planning, which could leave agencies vulnerable to supply disruptions during periods of drought or other supply shortages. The Act was adopted to require a minimum level of resource assessment and planning by water suppliers in order to reduce susceptibility to supply shortages. Water resources planning at the local level also allows for local community involvement and consideration of unique circumstances and local conditions of the individual agency. This 2015 UWMP is an update to CMWD’s 2010 UMWP. 1.2 Urban Water Management Planning Act This 2015 UWMP has been prepared in accordance with the Act, as amended, California Water Code Division 6, Part 2.6, §10610 through 10657. The Act became part of the California Water Code with the passage of Assembly Bill 797 during the 1983–1984 regular session of the California legislature. It requires every urban water supplier that provides water for municipal purposes to more than 3,000 connections or supplying more than 3,000 acre-feet (AF) of water annually to adopt and submit a plan every five years to the California Department of Water Resources (DWR). The Act was amended in November 2009 with the adoption of Senate Bill (SB) x7-7. SBx7-7 sets a goal of achieving a 20 percent reduction in urban per capita water use statewide by 2020. This 2015 UWMP recalibrates the baseline and targets established for SBx7-7 compliance in CMWD’s 2010 Plan. The agency will be held accountable to the targets set forth in this Plan. The Act states that urban water suppliers should make every effort to assure the appropriate level of reliability in water service is in place to meet the needs of its various categories of customers during normal, dry, and multiple dry years. The Act describes the required contents of the 2015 UWMP, as well as how urban water suppliers should adopt the UWMP. This 2015 UWMP has been developed in accordance with the DWR 2015 Urban Water Management Plans Guidebook for Urban Water Suppliers (2015 Guidebook), which provides guidance to agencies on how to include the information required under the California Water Code (CWC), as amended. In accordance with the CWC, this Plan must be adopted and submitted to DWR by July 1, 2016. June 2016 1-2 2015 Urban Water Management Plan Introduction and Overview Carlsbad Municipal Water District Final 1.3 Relation to Other Planning Efforts Urban Water Management Plans allow for integration of information from other planning documents, as well as regional planning efforts. This 2015 UWMP synthesizes information from CMWD’s current planning documents and complements regional planning documents. Upon completion, the 2015 UWMP will help to inform other planning decisions, such as updates to the Carlsbad General Plan, and can be used to establish priorities in other planning efforts. Further, the information developed for this 2015 UWMP will be used to inform and enhance the San Diego County Water Authority’s (SDCWA) 2015 Urban Water Management Plan, which provides water reliability assessment for the region’s water wholesaler. This 2015 UWMP aims to provide guidance on minimization of imported water supplies and maximization of local water supplies, which continues to be a priority for CMWD. CMWD has increased the use of recycled water, implemented water conservation measures, and participated in the planning of a local seawater desalination project as steps to maximize the use of local water resources. Relevant, related planning efforts include the following: 1. CMWD, 2012 Water Master Plan – Documents existing water system facilities and demands, identifies existing deficiencies in the system, confirms facility sizing, and recommends a future capital improvement program (CIP) based on updated water demand projections. 2. CMWD, 2012 Recycled Water Master Plan – Evaluates the capabilities of the existing recycled water system, defines the most cost-effective system expansions through build-out conditions, and develops a recycled water CIP. 3. CMWD, 2012 Phase III Recycled Water Project Feasibility Study – Identifies customer demands and establishes the pipeline expansion segments, recycled water supply, and appurtenances necessary for Phase III. 4. North San Diego Water Reuse Coalition (NSDWRC), 2015 Regional Recycled Water Project EIR – Identifies infrastructure between ten water and wastewater agencies interconnecting regional recycled water supply and distribution systems in order to maximize water reuse capacity. In the near term, this regional project potentially could supply additional non-potable demands of 18,808 acre-feet per year (AFY). 5. SDCWA, 2015 Urban Water Management Plan – Identifies regional water sources and volumes for SDCWA’s service area, including supply reliability analysis of the wholesale (imported + desalinated seawater) supply. 6. San Diego Regional Water Management Group (RWMG), 2013 San Diego Integrated Regional Water Management Plan – Regional effort to identify water resource issues, challenges, and solutions within western San Diego County, with emphasis on solutions that maximize collaboration and coordination among entities to best manage water resources. June 2016 2-1 Plan Preparation Section 2 Plan Preparation addresses CWMD’s basis for preparing an UWMP and related information. It also provides a description of how this 2015 UWMP is organized, and identifies general details regarding CMWD and the data used for this plan. 2.1 Basis for Preparing a Plan and Agency Identification This 2015 UWMP was prepared by CMWD. CMWD is a retail water agency that supplied 17,822 AF of water (potable and recycled) to over 86,000 people via 29,282 connections in 2015. Of these deliveries, 3,793 AF was recycled water, serving 761 recycled water connections, while the remaining 28,521 connections received a total of 13,264 AF potable water. Approximately 765 AF were lost as unmetered water. Unmetered water includes real losses, defined as physical water losses such as leaks, and apparent losses, which include “paper losses” or water lost through inaccurate measuring or recording. This 2015 UWMP was prepared as an individual plan in coordination with appropriate agencies. This chapter provides descriptions of agency coordination, public participation, Plan adoption, and Plan organization. Table 2-1, Table 2-2, and Table 2-3 provide information on CMWD as a retail water agency and its water system, and how data will be reported throughout the 2015 UWMP.

While preparing the 2015 UWMP, CMWD attended workshops conducted by DWR to discuss the requirements of the Act and attended meetings with SDCWA, CMWD’s wholesale water supplier. SDCWA’s 2015 Urban Water Management Plan should be consulted for details regarding CMWD’s wholesale water supplies. Table 2-4 identifies SDCWA as CMWD’s wholesale water supplier, with whom CMWD has coordinated on their supply and demand evaluations. Table 2-4: Water Supplier Information Exchange DWR Table 2-4 Retail: Water Supplier Information Exchange The retail supplier has informed the following wholesale supplier(s) of projected water use in accordance with CWC 10631. Wholesale Water Supplier Name San Diego County Water Authority CMWD worked closely with the City of Carlsbad’s Community and Economic Development Department in the preparation and review of 2015 UWMP elements. In preparing the recycled water elements of this 2015 UWMP, CMWD consulted with the agencies responsible for the existing and potential sources of recycled water in northern San Diego County, including Vallecitos Water District (VWD), Leucadia Wastewater District (LWWD), Encina Wastewater Authority (EWA), City of Escondido, City of Oceanside, Olivenhain Municipal Water District (OMWD), Rincon del Diablo Municipal Water District (Rincon), San Elijo Joint Powers Authority (SEJPA), Santa Fe Irrigation District (SFID), and Vista Irrigation District (VID). Table 2-5 provides a summary of CMWD’s coordination with the appropriate agencies.

CMWD held a public hearing on June 14, 2016, that provided an opportunity for CMWD’s customers (including social, cultural, and economic community groups) to learn about the water supply situation and plans to continue to provide a reliable water supply for the future. The hearing was an opportunity for people to ask questions regarding the 2015 UWMP and will include discussion of the per capita water use targets. A 60-day notice of the public hearing was provided to San Diego County and adjacent cities and other entities on March 31, 2016. A revised notice of 2015 UWMP availability was also provided to San Diego County and adjacent entities when the Revised Draft UWMP was released. The notification list is included in Appendix A. Public hearing notifications were published in the San Diego Union Tribune on May 24 and May 31, 2016. Copies of the 2015 UWMP were made available for public review at the City of Carlsbad’s June 2016 2-4 2015 Urban Water Management Plan Plan Preparation Carlsbad Municipal Water District Final Faraday Center, 1635 Faraday Avenue; at the Carlsbad City Library located at 1250 Carlsbad Village Drive; at the Carlsbad City Clerk’s Office, 1200 Carlsbad Village Drive, and on the City of Carlsbad’s website (www.carlsbadca.gov) two weeks before the public hearing. A copy of the published Notice of Public Hearing is included in Appendix A. This Plan was adopted by the Board of Directors on June 14, 2016. A copy of the adoption resolution is provided in Appendix B. The 2015 UWMP will be submitted to DWR, the California State Library, and San Diego County within 30 days after adoption. The 2015 UWMP will be available for public review on the City of Carlsbad’s website (www.carlsbadca.gov) within 30 days after filing a copy of the 2015 UWMP with DWR. The CMWD shall implement the adopted 2015 UWMP in accordance with the schedule described in this UWMP. 2.4 Plan Organization Section 1 provides an overview of the background and purpose of the Urban Water Management Planning Act and the 2015 UWMP. Section 2 describes the plan preparation process and plan organization. Section 3 provides a description of the service area, climate, and water system.

Section 7 provides an assessment of local and regional water supply reliability. Section 8 discusses water shortage contingency planning. Section 9 presents demand management measures. Section 10 discusses the plan adoption, submittal and implementation process. The appendices provide relevant supporting documents. DWR has provided a checklist of the items that must be addressed in each UWMP based upon the Act. This checklist makes it simple to identify exactly where in the UWMP each item has been addressed. The checklist was completed for this 2015 UWMP and is provided in Appendix C. It references the sections and page numbers where the specific items can be found. A copy of all of the required DWR tables has been provided as Appendix D. CMWD has elected to include additional tables in various chapters to provide clarity and support chapter narratives. Throughout this 2015 UWMP, tables are numbered sequentially, with tables containing information addressed in the required DWR tables indicated in the dark blue header row of the given table: Table 2-1: Retail: Public Water System Sequential Report Table Number DWR Guidebook Table Number June 2016 3-1 System Description This section describes CMWD’s service area and water system, including climate and water supply infrastructure. 3.1 Description of Service Area CMWD covers an area of 20,682 acres, approximately 32 square miles, and provides potable and recycled water supply to most of the City of Carlsbad (the City or Carlsbad). CMWD’s boundary, which defines the Study Area for this 2015 UWMP, is shown on Figure 3-1. CMWD supplies potable water within its service area and currently receives 100% of its potable water supply from SDCWA. The potable water distribution system consists of 450 miles of pipeline, 57 pressure regulating stations, five pump stations, ten storage tanks, and one reservoir. CMWD also has an extensive recycled water distribution system. CMWD supplies recycled water through two recycled water distribution systems, which include 77 miles of pipeline, five pressure zones, three storage tanks, three booster pumping stations, three supply sources with pumping stations, and three pressure regulating stations. Sanitary sewer collection service within the CMWD service area is provided by City of Carlsbad and LWWD. Wastewater treatment is provided by EWA through the Encina Water Pollution Control Facility (EWPCF), located in Carlsbad. Tertiary treatment and recycled water production is provided by CWMD’s Carlsbad Water Recycling Facility (WRF). Key water users within CMWD’s service area are residential, which represented 61% of total demands in 2015 and commercial, which included 19% of total demands in 2015. Carlsbad’s housing stock composition consists of mostly single-family homes, with some multi-family and mobile homes. Single- family residences generally contain larger landscaped areas, predominantly planted in turf, and require more water for outdoor application in comparison to other types of housing. The general characteristics of multi-family and mobile homes limit their outdoor landscaping and water use, although some condominium and apartment developments do contain green belt areas. Commercial users in CMWD’s service area include offices and commercial centers, which have limited outdoor water use, but also include hotels, resorts, golf courses, and other tourism and recreational facilities. As described below, Carlsbad’s visitor rates are often equal to or higher than its residential population in a given month. Additional information regarding these key users, along with other important water use sectors, is included in Section 4 System Demands. 3.1.1 Agency Organizational Structure CMWD is a subsidiary district of the City of Carlsbad. The City was incorporated in 1952, and the assets of the two previous water suppliers for the Carlsbad area were purchased by the City in 1957. CMWD was initially formed in 1954 to facilitate the transfer of imported water to the unincorporated areas surrounding the City and to wholesale water to the newly formed City. In 1983, the City conveyed all of its functional water responsibilities for the provision of water service to CMWD. In 1990, CMWD became a subsidiary district to the City of Carlsbad. The five-member Carlsbad City Council governs CMWD and acts as CMWD’s Board of Directors. CMWD’s service area covers approximately 77.6% of the incorporated City. Additional history of water services within CMWD’s service area is provided in Section 3.2 Water System Background, below.

This mild climate is derived equally from the warm ocean water being pulled north from Mexico and from its subtropical, semi-desert locale. The result is temperatures with an average high of 64 degrees in January and 75 degrees in August, with an average annual rainfall of about 11 inches. Data from the National Oceanic and Atmospheric Administration’s (NOAA) climate station at the McClellan Palomar Airport shows that 2015 temperatures were above normal (calculated for the 30-year period 1981 to 2010), while precipitation was lower than normal. There was also a shift in the precipitation pattern in 2015 from normal, with higher rainfall in the summer months than normal, and lower rainfall in the winter months. Figure 3-2 provides a comparison of 2015 precipitation and mean monthly temperatures with normal climate, as recorded at the McClellan Palomar Airport. A detailed discussion of potential climate change impacts to CMWD’s service area is provided in Section 3.1.6 Climate Change, below. Figure 3-2: Comparison of 2015 Climate to Normal for Carlsbad, California Source: NOAA, 2016a and 2016b 3.1.3 Population and Demographics To accurately project CMWD's future water demands and water use characteristics, future population and growth trends are essential. The population projections presented in Table 3-1 were developed using San Diego Association of Government (SANDAG)’s Series 13 Growth Forecast for CMWD’s service area. A secondary analysis was completed to confirm the SANDAG projection, using U.S. Census-based estimates for population in 2010. This analysis compared CMWD’s estimated population in 2000 and 2010 with the Census population for the City of Carlsbad to verify the projections from SANDAG. In 2000, the City recorded a population of 78,247 people with the U.S. Census, while a Geographical Information System (GIS) analysis of population data by census block found CMWD’s service area included 61,261 people (78% of the City’s population).

CMWD has therefore assumed its population is approximately 77.6% of the City of Carlsbad, as the average of the two Census years evaluated. Table 3-1: CMWD’s Service Area Population – Current and Projected DWR Table 3-1 Retail: Population - Current and Projected Population Served 2015 2020 2025 2030 2035 2040 86,080 91,935 94,130 96,375 97,239 97,525 NOTES: Projections used 2010 Census data (77.6% of City of Carlsbad population), 2020-2040 projections from SANDAG Series 13 model for CMWD service area, and a straight line projection from 2010-2020 for year 2015. Water use in CMWD’s service area is closely linked to the local economy, population, and weather. Over the last half century, a prosperous local economy has stimulated population growth, which in turn produced a relatively steady increase in water demand. However, fluctuating economic and weather conditions in the 1990s and lingering effects from the 1987-1992 drought resulted in deviations from historic demand patterns. By 1999, a new combination of natural population increases and job creation surfaced as the primary drivers of water consumption increases. The recession that started in 2008 brought an increase in unemployment and decrease in housing prices that has dampened population growth and water use. In addition, CMWD adopted a residential tiered water rate in July 2009 which further dampened demand by the residential population. Current demands are limited as a result of drought response measures and State-mandated water use cutbacks. As described in Section 4 System Demands, CMWD’s service area is host to a substantial tourist and temporary population throughout the year, with overnight guests in the City of Carlsbad ranging between approximately 75,000 and 199,000 people per month. Water use is further described in Section 4 System Demands and Section 5 Baselines and Targets. 3.1.4 Existing and Future Development The City’s 2015 General Plan Update identifies current land uses, including residential, commercial and industrial, public and quasi-public uses, parks and recreation, agriculture, open space or natural areas, and vacant land. The remaining land is right-of-way (City of Carlsbad, 2015a). Table 3-2 provides a summary of the land use classifications within the CMWD service area, as compared to the City of Carlsbad. Table 3-2: Land Use Classifications within City of Carlsbad and CMWD Land Use Classification Percent of City of Carlsbad1 Percent of CMWD2 Residential 27% 24% Commercial and Industrial 8% 14% Public and Quasi-Public Uses 6% 1% Parks and Open Space 33% 30% Agriculture 4% 6% Rights-of-Way 13% 14% Vacant 9% 11% 1. City of Carlsbad, 2015a 2. CMWD, 2011 June 2016 3-5 2015 Urban Water Management Plan System Description Carlsbad Municipal Water District Final As of 2013, the City of Carlsbad had 44,440 housing units, or just over 81% of the maximum 54,599 housing units allowed in the City’s Growth Management Plan. Between 2000 and 2010, the City grew by almost 30,000 people, or a rate of 2.5%, substantially higher than the 0.9% growth rate experienced by San Diego County as a whole. The City’s General Plan estimates buildout at 51,821 housing units by 2035, or nearly 95% of the maximum allowed under the Growth Management Plan. The majority (80%) of this growth is projected to occur within the Northwest and Northeast quadrants of the City, both within CMWD’s service area (City of Carlsbad, 2015a). Existing land uses within the CMWD service area are primarily residential and parks and open space, with a mix of agricultural, light industrial, and commercial. Additionally, a county airport, tourist attractions such as Legoland, and a mix of resorts are located within CMWD’s service area. Residential uses make up approximately 24% and parks and open space make up approximately 30%. Vacant land makes up approximately 11% of CMWD’s service area (CMWD, 2011). According to SANDAG’s Series 13 Growth Forecast land use projections, an additional 1,038 acres are anticipated to be developed within CMWD’s service area between 2015 and 2040. The bulk of this development will increase single-family, industrial, and commercial land; a decrease will occur in agricultural land. Although some land uses are anticipated to grow or decrease by a few hundred acres, most land use categories are anticipated to continue to represent a similar proportion of total developed area within CMWD’s service area. For example, single-family residential land use is 35% of CMWD’s developed area in 2015, and despite growing by over 700 acres between 2015 and 2040, will only represent 38% of CMWD’s total developed area in 2040. Table 3-3 shows the projected land uses within CMWD’s service area, as a percentage of total developed land.

As of February 2010, CMWD contains nearly 36,000 residential units and just over 16 million square feet of non-residential building area (CMWD, 2011). Projected total buildout for CMWD’s service area includes 40,068 residential units and approximately 25 million square feet of non-residential building space (CMWD, 2011). Planned development within the City of Carlsbad is anticipated to include a mix of residential and mixed-use developments. These planned developments are expected to occupy the majority of the remaining vacant land in CMWD’s service area (CMWD, 2011). June 2016 3-6 2015 Urban Water Management Plan System Description Carlsbad Municipal Water District Final 3.1.5 Overview of Significant Water Uses The primary water uses in CMWD’s service area are residential, commercial and industrial, agricultural, and irrigation. Residential water use represents the largest water use sector for CMWD. Residential water uses include both indoor and outdoor uses for single-family and multi-family categories. Commercial water uses generally consist of incidental uses necessary for business operation. Major commercial water uses include restaurants, car washes, laundries, hotels, as well as institutional uses including schools and churches. Industrial water uses consist of product processing, equipment cooling, sanitation and air conditioning. Agricultural water uses are relatively minor, and primarily consist of commercial strawberry and flower fields, and wholesale nursery operations. Irrigation water uses fluctuate by season and primarily include the irrigation of medians, slopes and parkways. Detailed information of CMWD’s water use sectors can be found in Section 4.1.1 Water Uses by Sector. 3.2 Description of Water System CMWD currently receives 100% of its potable water supply from SDCWA through four treated water turnouts. Two of the turnouts, Connections No. 1 and No. 2, are direct connections to SDCWA’s Second Aqueduct. Connection No. 1 supplies only CMWD, and Connection No. 2 supplies CMWD, VWD, and OMWD. Water supply to CMWD from Connection No. 2 is delivered through a VWD transmission main. Connections No. 3 and No. 4 are on SDCWA’s Tri-Agency Pipeline (TAP), which is also supplied from the Second Aqueduct. The TAP also serves the City of Oceanside and VID. Major water infrastructure facilities are shown in Figure 3-3. Potable water is delivered within the CMWD service area through 450 miles of pipeline, 17 pressure zones, 57 pressure regulating stations, five pump stations, ten storage tanks, and one reservoir. The CMWD water distribution system is flexible in that supply from the four aqueduct connections can be routed to different parts of the distribution system, as needed. The total operational storage for CMWD is 245.5 million gallons (MG), which includes the 195 MG Maerkle Dam Reservoir. CMWD also has an extensive recycled water distribution system, shown in Figure 6-1 in Section 6 System Supplies. CMWD supplies recycled water through two recycled water distribution systems, which include 77 miles of pipeline, five pressure zones, three storage tanks, three booster pumping stations, three supply sources with pumping stations, and three pressure regulating stations. CMWD supplies a majority of recycled water from the Carlsbad WRF, owned by CMWD and operated by EWA. Recycled water is also served to a portion of the La Costa Resort and Spa through a second recycled water system supplied by LWWD’s Gafner WRF. Finally, a portion of the eastern service area is served by the third system supplied by VWD’s Meadowlark WRF. CMWD is currently in the process of expanding their recycled water system with the Phase III Recycled Water Project, which will construct an additional 18 miles of recycled water pipeline, install 156 metered service connections, expand the capacity of the Carlsbad WRF from 4.0 mgd to 8.0 mgd, and construct a 1.5 MG storage reservoir (CMWD, 2012).

The Carlsbad Mutual Water Company constructed nine wells in the Mission Basin of the San Luis Rey River, booster pumping stations, storage tanks, an earthen dam (Lake Calavera), and transmission facilities to supply residential, commercial and agricultural users. The Terramar Water Company constructed four wells located in Agua Hedionda Creek (referred to as the Cannon Well Field), a second connection to the Carlsbad Mutual Water Company’s pipeline from Lake Calavera at El Camino Real, a reservoir, plus a distribution system to supply residential, commercial, and agricultural users. The Carlsbad Mutual Water Company’s groundwater wells began being developed prior to 1914 with rights to 2,382 AFY. In addition, a license was obtained (terminable by the State Division of Water Rights, Department of Water Resources [DWR]) for another 1,000 AFY. A total of 9 wells were eventually constructed in the Mission Basin of the San Luis Rey River located in the City of Oceanside generally near the intersection of Mission Avenue and Fousat Road. Prior to 1942, local groundwater was the only developed source of water for the Carlsbad Mutual Water Company. In September 1941, Carlsbad Mutual Water Company completed construction of an earthen dam (Calavera Dam), which captured local surface water runoff creating Lake Calavera. Lake Calavera also included a 2 million gallons per day (mgd) water filtration plant. A permit to divert 150 AFY from Calavera Creek was obtained. The Cannon Well Field’s four wells were constructed beginning in 1950, and are approximately located at the Rancho Carlsbad Golf Course property. The groundwater pumped from these wells was the original supply for the Terramar Water Company, and had a safe yield capacity estimated at 400 AFY. This groundwater was obtained from the Carlsbad hydrologic unit of the San Diego Region, a designation assigned by DWR. The four wells remain, but are in a state of disrepair and will need to eventually be removed and new replacement wells constructed. The City of Carlsbad was incorporated in 1952, and the assets of the Carlsbad Mutual Water Company and Terramar Water Company were purchased by the City of Carlsbad in an agreement dated August 30, 1957. The City operated and maintained both water systems from 1958 to 1962. CMWD was formed in 1954 as a vehicle to bring imported water to the unincorporated areas surrounding the City of Carlsbad and to wholesale water to the newly formed City of Carlsbad. CMWD’s first meeting was held on March 22, 1954, and CMWD became a member of SDCWA CMWD’s 8.5 MG D3 Reservoir June 2016 3-9 2015 Urban Water Management Plan System Description Carlsbad Municipal Water District Final that same year. CMWD began receiving imported water deliveries in 1955 through existing aqueduct connections located in the City of Escondido. CMWD constructed a pipeline in 1956 to convey imported water directly to the City of Carlsbad and unincorporated areas within CMWD’s service area. In 1962, CMWD constructed Maerkle Dam (previously called Squires Dam) with a capacity of 600 AF in the Agua Hedionda Basin. CMWD also obtained a permit for surface water rights tributary to Maerkle Dam in the amount of 25 AFY. As demands for water increased, seawater intrusion into the groundwater supply resulted in the gradual degradation of groundwater quality in the Mission Basin of San Luis Rey River. The total dissolved solids (TDS) content of the groundwater in the Mission Basin increased to the point where treatment would be required. At the same time, lower-cost imported water became available through CMWD. As a result of the availability of this alternative supply of water, the City of Carlsbad ceased extracting groundwater and suspended use of local surface water supplies by the end of 1962. As a result, the water filtration plant at Lake Calavera was dismantled because of regulations requiring that surface waters be fully treated prior to introduction into a potable water system. The cost to construct facilities to treat the small amount of infrequently occurring surface water was determined to be much greater than the comparable cost of imported water. The Mission Basin wells were beyond repair and subsequently removed by 2005, in accordance with California Department of Public Health requirements. In an agreement dated May 25, 1983, the City of Carlsbad conveyed all of its functional water responsibilities for the provision of water service to CMWD, including all the water facilities and groundwater and surface water rights purchased from Carlsbad Mutual Water Company and Terramar Water Company in 1957. This included all existing water facilities and responsibility for planning, financing, and construction of all major capital facilities necessary to provide potable water service within CMWD and portions of the City of Carlsbad not located in other retail water service agencies. On January 1, 1990, CMWD became a subsidiary district of the City of Carlsbad through an agreement between both agencies approved by the City Council on April 25, 1989. From 1979 until joining with the City as a subsidiary district, CMWD was known as the Costa Real MWD. The Carlsbad City Council acting as CMWD’s Board of Directors governs CMWD. CMWD’s current water supplies consist of treated water purchased from SDCWA and recycled water. In April 2016, CMWD’s Board approved a purchase agreement to receive desalinated seawater directly from SDCWA, along with the purchased water blend provided to all member agencies. SDCWA’s supply mix includes desalinated seawater, imported water purchased from MWD (treated at MWD’s Skinner Filtration Plant in Riverside County), and through purchase agreements and exchanges with other agencies. SDCWA supplies delivered to CWMD are also treated at SDCWA’s Twin Oaks Water Treatment Plant in San Marcos, and conveyed to CMWD through SDCWA aqueducts. 3.4 Climate Change 3.4.1 Climate Action Plan and Energy Intensity of Water System The City of Carlsbad has developed a Climate Action Plan (City of Carlsbad, 2015b) that in part identifies actions to reduce its GHG emissions. Government operations, including CMWD’s operations, produce only 1.2% of the City’s GHG emissions. CMWD’s operation and maintenance activities were estimated to use 189,440 kWh electricity and 86 terms of natural gas in 2011, or 2% and less than 0.01% of the government operations energy demands, respectively, for buildings. Water and wastewater transport (conveyance and distribution system) used over 2.3 million kWh in 2011, or 10% of the entire government operations emissions (0.12% of citywide emissions). The Climate Action Plan identifies a number of actions to reduce GHG emissions, including those presented in Table 3-4, which June 2016 3-10 2015 Urban Water Management Plan System Description Carlsbad Municipal Water District Final are GHG reduction actions associated with water and wastewater facilities and operations. A detailed discussion of energy intensity of CMWD’s 2015 supplies is provided in Section 6 System Supplies. Table 3-4: Water- and Wastewater-Related GHG Emissions Reduction Measures Included in 2015 Climate Action Plan Goal Action Reduce intensity of GHG emissions from water utilities (including water supply, wastewater, and recycled water) conveyance, treatment, and distribution by 8 percent by 2035 Improve water utilities (including water supply, wastewater, and recycled water) conveyance, treatment and distribution, and other system improvements (e.g., replace sewer lift stations with gravity pipelines; increase utilization of methane capture and cogeneration; expand recycled water distribution system) Encourage installation of greywater and rainwater collection systems with a goal of 15 percent of homes by 2035 Host workshops on greywater and rainwater collection systems through CMWD, or partner with existing workshop providers, or homeowners interested in installing systems suitable for their property Created a design reference manual, or provide links to an existing one, for the design of greywater and rainwater collection systems Evaluate the feasibility of offering a rebate for residential greywater systems that require a permit to cover the cost of obtaining a permit Source: City of Carlsbad, 2015b. 3.4.2 Climate Change Vulnerability Analysis As an agency with limited local water supplies and located in a coastal area that could be subject to impacts from sea level rise, climate change is of concern to CMWD. CMWD is an active participant in the San Diego Integrated Regional Water Management (IRWM) Program, having been a member of the Regional Advisory Committee (RAC) since 2013. In 2013, the IRWM Program completed an update of the San Diego IRWM Plan (RWMG, 2013), which collated regional water management information and identified water management priorities for the region. Through this effort, a Climate Change Vulnerability Analysis was completed and included in the San Diego IRWM Plan (refer to Section 7 and Appendix 7-D of the San Diego IRWM Plan). While this analysis evaluated climate change vulnerabilities and identified priorities and actions for the region as a whole, it generally corresponds closely with CMWD’s individual vulnerabilities, priorities, and potential actions. The San Diego region anticipates experiencing temperature increases, sea level rise, and changes to precipitation patterns. Table 3-5 presents the potential climate change impacts to the San Diego region, as presented in the San Diego IRWM Plan Climate Change Vulnerability Analysis. Regional climate change vulnerabilities that are applicable to CMWD and its service area are presented in Table 3-6, and include decreased imported supplies, sensitivity due to higher drought potential, damage to coastal areas and inundation of storm drains and sewer systems from sea level rise, and decreases in available habitat for native species.

June 2016 3-12 2015 Urban Water Management Plan System Description Carlsbad Municipal Water District Final Following identification and prioritization of regional climate change vulnerabilities, the San Diego IRWM Plan Climate Change Vulnerability Analysis identified and prioritized strategies to mitigate and adapt to the identified vulnerabilities. These strategies were grouped into Tier 1, 2, and 3, which represent actions that are recommended to implement first, second, and third, based on ease, effectiveness, and contribution to reducing greenhouse gas (GHG) emissions. Table 3-7 presents the Tier 1 strategies that are applicable to CMWD. A complete list of strategies is provided in Appendix E, along with the vulnerability indicator question assessment completed for the Climate Change Vulnerability Analysis. Table 3-7: Tier 1 Climate Change Management Strategies Relevant to CMWD and its Service Area Strategy Description Reduce Water Demand Urban water use efficiency Technological and behavioral improvements that decrease indoor and outdoor residential, commercial, industrial and institutional water use. Education Implement outreach program to educate urban and agricultural water users in water demand reduction practices. Gray water use Implement gray water use systems to reduce water supply demand. Rainfed agriculture Transfer crop consumptive use to be supplied directly by rainfall. Improve Operational Efficiency/Transfers Conveyance - Regional/local Improvements to regional and local conveyance facilities that improve conveyance capacity. System Reoperation Change existing operation and management procedures for existing reservoirs and conveyance facilities to increase water related benefits from these facilities. Increase Water Supply Recycled Municipal Water Increase supply of recycled water through additional wastewater treatment, and/or expand conveyance of recycled water to end users. Improve Water Quality Pollution Prevention Prevent pollution of local surface waters and groundwater using tools that prevent point and non-point sources of pollution. Salt and Salinity Management Manage salt and salinity in surface and/or groundwater. Examples of methods include dilution and displacement, desalination, and salt collection and storage. Urban Runoff Management Prevent pollution of local surface waters by implementing best management practices (BMPs) designed to reduce the pollutant loading and reduce the volumes and velocities of urban runoff discharged to surface waters. Improve Flood Management Flood Risk Management Enhance flood protection through projects and programs that assist in the management of flood flows and to prepare for, respond to, and recover from a flood.

June 2016 4-1 System Water Use This section addresses current and projected system water use for CMWD’s service area. System water use consists of water used by CMWD, water sold to others, and additional water uses and losses. Tables 4-1 and 4-5 present the current (2015) and projected (through 2040) potable water sales, respectively, including demands from low-income households. CMWD’s demand projections presented in this section meet CMWD’s gallons per capita per day (gpcd) demand targets that are described in Section 5 Baselines and Targets. Figure 4-1 shows historical, current, and projected water use within CMWD’s service area by use type. Note that non-potable recycled water use is included. Figure 4-1: Historical, Current, and Projected Water Use 4.1 Existing Water Use and Demands Existing water use and demands are based on metering data for calendar year 2015. Water use consists of water used by CMWD, water sold to others, and additional water uses and losses. Table 4- 1 presents the current potable water sales by customer sector for 2015. In addition to potable water, CMWD also provides recycled water to some of its customers. Current and projected recycled water demands are summarized in Table 4-3, with a detailed discussion of CMWD’s recycled water supplies and demands in Section 6 System Supplies. 0 5,000 10,000 15,000 20,000 25,000 2005 2010 2015 2020 2025 2030 2035 2040Water Use (AFY)Single Family Landscape Commercial Multi-Family Water Loss Agricultural Institutional Industrial Recycled Water June 2016 4-2 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final Table 4-1: 2015 Demands for Potable and Raw Water DWR Table 4-1 Retail: Demands for Potable and Raw Water - Actual Use Type 2015 Actual Level of Treatment When Delivered Volume (AFY) Single Family Drinking Water 7,088 Multi-Family Drinking Water 1,526 Commercial Drinking Water 2,721 Industrial Drinking Water 6 Institutional Drinking Water 159 Agricultural Drinking Water 181 Landscape Drinking Water 1,583 Water Losses Drinking Water 765 TOTAL 14,029 NOTES: CMWD does not serve raw water to customers; all non-recycled water is potable. Actual potable water demands are based on CMWD’s 2015 billing data and the AWWA water loss audit (refer to Appendix F for the complete audit). The AWWA water loss audit was completed for FY2015 as the most recent water loss data available, while billing data are reported in calendar year. CMWD’s temporary potable meters billing category was incorporated into the Single Family use type, while the fire protection billing category was incorporated into the Institutional/Governmental use type for consistency with demand projection categories for 2020 through 2040. 4.1.1 Water Use by Sector CMWD’s potable water system serves water to four major sectors: 1) Residential (single-family and multi-family); 2) Commercial/Industrial/Institutional (CII) (reported as three separate sectors); 3) Agricultural; and 4) Landscape. A brief description of each sector and factors affecting their water use is provided here. In addition to the four major sectors, tourism and temporary residents create a substantial demand for water within CMWD’s service area. These temporary population increases affect demands, but their impacts are not always captured to their true extent in reported metrics. A brief narrative of the tourism sector in CMWD’s service area is provided below. Table 4-1 presents current potable water demands of these sectors in 2015. Residential Residential water use represents the largest water use category for CMWD and includes both single- family and multi-family customers. Residential water consumption comprises both indoor and outdoor uses. Residential indoor water use includes sanitation, bathing, laundering, cooking, and drinking. The majority of outdoor residential water use satisfies landscaping irrigation needs. Other minor outdoor residential water uses include car washing, surface cleaning, and similar activities. Total residential water use is anticipated to increase over time as CMWD’s service area reaches residential buildout, though an increased culture of conservation and water use restrictions are likely to result in a lower per-capita increase in demands compared to historical growth. Residential land use currently occupies almost 5,200 acres, and is anticipated to continue to expand to approximately 5,970 acres by 2040. June 2016 4-3 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final Commercial/Industrial/Institutional Commercial water use generally consists of incidental uses necessary for the operation of a business or institution, such as drinking, sanitation, and landscape irrigation. Major commercial water users include service industries such a restaurants, car washes, laundries and hotels. Statistics indicate that almost 60% of Carlsbad’s employment base is in the commercial sector. This sector is anticipated to grow substantially in the near future, as infill development in the Carlsbad Village is implemented, and additional hotel properties developed to support the City’s growing tourism economy. Commercial land use is anticipated to grow from 1,214 acres in 2015 to 1,470 acres in 2040. Industrial water use consists of a wide range of uses, including product processing and small-scale equipment cooling, sanitation and air conditioning. Water-intensive industrial uses in Carlsbad, such as electronics manufacturing and biotech research, typically require smaller amounts of water when compared to other water-intensive industries found elsewhere in Southern California, such as petroleum refineries, chemical processors, and canneries. Industrial land use is anticipated to expand by over 350 acres in the next 25 years, from 1,599 acres today to 1,951 acres in 2040. Institutional water use consists primarily of schools and churches within the service area. Water use characteristics tend to be similar to commercial uses, but based on average daily attendance. Outdoor use also tends to be somewhat higher for landscaped areas and ball fields. However, many of these areas tend to be metered separately and categorized as irrigation. Institutional land uses are anticipated to grow 50 acres between 2015 and 2040, increasing from 229 acres to 279 acres. Tourism and Temporary Residents Included in CMWD’s CII water uses are tourism-related water demands. Within the City, overnight visitors averaged over 162,402 people per month for 2014, with tourism rates estimated to exceed 2 million visitors for 2015 (Heagy, pers.comm. 2016a). With a permanent population estimated at approximately 111,000 in 2015, the City’s population has more than doubled on a monthly basis when considering temporary residents. Visitors are drawn to Carlsbad for its proximity to attractions in San Diego County, Legoland, nearby state beaches, and other general lifestyle factors that make Southern California a tourist destination. The tourism industry in Carlsbad affects water usage by not only the number of visitors, but also through the expansion of service industries and attractions, which tend to be larger outdoor water users. Tourism peaks during summer months, particularly July and August, but is high throughout the year. The peaking experienced in summer months affects seasonal demand and water system peaking. Population forecasts do not specifically account for tourism, but tourism is reflected in the economic forecasts and causes per capita use to increase. Tourism can also Recycled water use at golf course in CMWD’s service area June 2016 4-4 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final increase per capita demands because tourists are less likely to be as conscientious with their water use as locals. Tourists may not be familiar with water-wise practices (e.g., shorter showers, turning off faucets when brushing teeth) or are in “vacation mode” and not actively aware of their water use. They may also be engaging in inherently water-heavy tourism-based activities. Agricultural Agricultural water use has been decreasing in Carlsbad for the last two decades to the point that it currently represents a very small portion of CMWD’s water demand. For example, in 1991 CMWD sold 1,744 AF to agriculture. By 2000, the agriculture consumption had declined to 1,204 AF, to 420 AF in 2010, and to 181 AF in 2015. By 2040, agricultural demands are projected to drop to only 69 AFY. The Agricultural sector experiences wide seasonal fluctuations due to weather conditions and timing of the growing seasons, and consists primarily of commercial strawberry and flower fields, and wholesale nursery operations. Agricultural land use is anticipated to continue to decrease from a current extent of 535 acres to an estimated 102 acres by 2040 (SANDAG, 2016). Landscape Landscape irrigation is the third largest water use in CMWD’s service area, just behind commercial water use, and demands are strongly influenced by seasonal differences. Development within the City of Carlsbad over the last decade and a half has brought about the creation of a large amount of irrigated areas with various uses, including medians, slopes and parkways. The City of Carlsbad adopted a Landscape Manual in November 1990 to assist development applicants and landscape architects in understanding the City’s policies toward landscaping. Specifically, the manual requires that irrigation systems be designed to provide the optimum amount of water for plant growth without causing soil erosion or runoff. At the same time, it requires that landscape design will include water conservation and alternative (non-potable) water sources as primary criteria. This manual was updated in 2012 and incorporates Carlsbad Municipal Code Chapter 18.50 – Water Efficient Landscape Ordinance (WELO), among other changes. In May 2010, the City of Carlsbad adopted the WELO in accordance with the State’s Water Conservation in Landscaping Act of 2006 (Assembly Bill 1881). This Act promotes consistency in landscape regulations among land use authorities throughout San Diego County. The regulations reflect improvements for landscape and irrigation design plans, irrigation technologies, and water management for achievable water savings. Total irrigated land use areas, including roadways and parks, are anticipated to remain relatively constant between 2015 and 2040, decreasing by only 8 acres, or approximately 0.2%. Landscape irrigation is also a substantial recycled water user within CMWD’s service area. Recycled water is regulated by CMWD’s Reclamation Rules and Regulations for Construction of Reclaimed Water Mains (1993) and Mandatory Use Ordinance (Ordinance No. 43, 2005), the San Diego Regional Water Quality Control Board’s reclamation permits and waste discharge requirements for CMWD’s Carlsbad WRF (Order No. 2001-352, as amended by Order No. R9-2012-0027), LWWD’s Gafner WRF (Order No. R9-2004-0223), and VWD’s Meadowlark WRF (Order No. R9-2007-0018), and California’s Title 22 regulations. 4.1.2 Additional Water Uses Additional water uses include recycled water and other uses such as fire protection. Recycled water is used by irrigation customers to water golf courses, median strips and other landscaped areas. Overall, recycled water use represents 22% of total water use in CMWD’s service area for 2015. Recycled water use tends to be lower in the winter months because of less irrigation demand for landscape, the primary use for recycled water. Recycled water use is projected to increase in the near future through June 2016 4-5 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final implementation of the Phase III Recycled Water Project and increased awareness of safe and appropriate use of recycled water. Recycled water use is addressed in greater detail in Section 6 System Supplies. 4.1.3 Distribution System Water Losses System losses or unaccounted-for water use (UAW) is unmetered water use such as for water system flushing, sewer cleaning, system leaks, unauthorized connections, reservoir cleaning, and other municipal uses. Unaccounted-for water can also result from meter inaccuracies. As required by the 2015 Guidebook, CMWD completed a water loss audit using the American Water Works Association (AWWA) Water Audit methodology (see Appendix F). Apparent losses (unauthorized consumption and metering inaccuracies) were calculated as 233 AFY, while Real Losses were calculated at 532 AFY, for a total loss of 765 AFY. Unlike the rest of the data presented in this UWMP, the Water Loss Audit was completed for Fiscal Year 2014/15, while the rest of the UWMP reports data from calendar year 2015. 2015 water losses are therefore considered approximate. Calculated water losses for CMWD’s water system are shown in Table 4-2. Based on FY2015 losses, CMWD anticipates that water losses represent 4.7% of total potable use, calculated as the volume of water loss (765 AF) divided by the total volume of water produced (16,241 AF). Projected water losses presented in Table 4-6 are estimated using this proportion. Table 4-2: 2015 Water Losses (AFY) DWR Table 4-4 Retail: 12 Month Water Loss Audit Reporting Reporting Period Start Date Volume of Water Loss 07/2014 765 NOTES: Water losses are reported in Fiscal Year, while the rest of the water use tables use 2015 Calendar Year data. 4.1.4 Sales to Other Agencies CMWD does not currently sell potable water to other agencies, nor does it anticipate doing so in the future. CMWD does not currently have its own local potable water supply, though it may utilize groundwater and may receive desalinated seawater directly from the Claude “Bud” Lewis Carlsbad Desalination Plant (Carlsbad Desalination Plant) in the future. CMWD sells a portion of the recycled water it produces at the Carlsbad WRF to customers of neighboring agencies to help meet their non- potable water demands, but does not sell recycled water directly to any other agency. In 2015, CMWD sold 42.4 AF of recycled water through nine meters (customers) located within the City, but within VWD’s service area. As part of the NSDWRC, CMWD anticipates there may be potential future recycled water sales to additional customers of other agencies, generally building on recycled water system expansions designed to primarily serve CMWD’s service area. 4.1.5 Estimating Water Savings from Codes, Ordinances, or Transportation and Land Use Plans CMWD is actively encouraging customers to reduce potable water use through the increased use of recycled water, installation of water-wise landscaping, replacement of fixtures with water-saving and low-flow devices, and outreach and educational campaigns. Section 9 Demand Management Measures provides details on CMWD’s efforts to encourage water conservation. CMWD’s future water savings resulting from increased conversion from potable to recycled water through its Phase III Recycled Water Project’s expansion of its recycled water system is included in future water use projections. Compliance with applicable regulations and codes requiring use of low-flow fixtures in new June 2016 4-6 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final construction will result in passive savings. Passive savings are reflected in CMWD’s SBx7-7 target water use, and therefore incorporated into the demand projections presented in Section 4.3 Projected Total Water Use and Demand Projection Provided to Wholesaler. Table 4-3: Inclusion of Future Water Savings and Lower Income Demands DWR Table 4-5 Retail Only: Inclusion in Water Use Projections Are Future Water Savings Included in Projections? Yes If "Yes" to above, state the section or page number, in the cell to the right, where citations of the codes, ordinances, etc… utilized in demand projections are found. Page 2-5 Are Lower Income Residential Demands Included In Projections? Yes On June 21, 2005, CMWD’s Board of Directors adopted Ordinance No. 43. This ordinance, also referred to as CMWD’s Mandatory Use Ordinance, requires customers to use recycled water “wherever it has determined that its use is economically justified, financially and technically feasible, and consistent with legal requirements, preservation of public health, safety and welfare, and the environment.” As a result of this ordinance, new development is prepared to convert to recycled water for irrigation purposes once recycled water becomes accessible. CMWD has identified a large number of potential recycled water customers who are prepared to utilize recycled water, as appropriate, in accordance with Ordinance No. 43. CMWD’s ability to meet these customers’ recycled water demands now and in the future has been included in its recycled water use and recycled water supply projections. As recycled water use increases, CMWD’s per capita potable water use will decrease, helping to achieve the SBx7-7 targets. In addition to potable water use savings achieved through conversion to recycled water, CMWD anticipates water savings resulting from compliance with water efficiency regulations. A number of regulatory changes have been made in recent years to encourage or mandate the use of low-flow and efficient plumbing fixtures, along with improvements to building standards to encourage green building. These changes include, but are not limited to, AB 715 (efficient toilets and urinals) and SB 407 (retrofitting for efficient fixtures). Prior to 2010, CMWD’s water use was generally above its SBx7- 7 target, though CMWD has successfully taken measures to reduce per capita water use since the Water Conservation Act of 2009 was enacted. CMWD has met or exceeded its SBX7-7 targets every year since 2010. Conservation measures implemented by CMWD include installation of water efficient fixtures and turf replacement, as described in Section 9 Demand Management Measures. New development in CWMD’s service area will be constructed compliant with all applicable codes, and mandatory retrofits will be implemented, as applicable. The reduced water use resulting from these codes and regulations have been incorporated into CMWD’s demand projections because they are reflected in the decreased per capita demands of the SBx7-7 targets. Because much of the existing development in the City of Carlsbad is relatively new, many residences, commercial buildings, and other facilities already use lower flow devices, and there are limited opportunities or need to retrofit existing structures to further improve water use efficiency to increase passive savings for existing development. Recent reductions in water use and SBx7-7 compliance is discussed in greater detail in Section 5 Baselines and Targets. June 2016 4-7 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final 4.1.6 Climate Change Effects on Demand As discussed in Section 3 System Description, CMWD is vulnerable to the effects of climate change, in large part due to its reliance on imported water to meet potable demands. As a participant in the San Diego IRWM Program, CMWD contributed to the climate change vulnerability assessment prepared for the 2013 San Diego IRWM Plan (SDRWMG, 2013), the results of which are summarized in Section 3 System Description. The complete assessment is included here as Appendix E. Preliminary analysis indicates that regional water demands would show a slight increase of between 0.6% – 1.8% by 2035. These increases in demand are anticipated to be associated with increased temperatures, increased drought potential, and increased wildfire potential, coupled with increased variability in rainfall that may reduce the availability of local supplies and/or the ability for vegetation to access natural water supplies when they need them. Within the San Diego region as a whole, five water demand vulnerabilities were identified, four of which apply to CMWD’s service area. These vulnerabilities include potential increases in industrial and crop demands, a limited ability to conserve further, and a limited ability to meet summer demand. Table 3-6 in Section 3 System Description presents these vulnerabilities and their priorities for CMWD. None of the water demand vulnerabilities applicable to CMWD were classified as very high or high priority. CMWD has taken steps to address water demand vulnerabilities by increasing supply reliability and expanding use of local and recycled water supplies, as well as encouraging improved water use efficiencies (refer to Section 6 System Supplies, Section 7 Water Supply Reliability Assessment, and Section 9 Demand Management Measures). As described below, agricultural land use is anticipated to decrease, reducing the impact of increases in crop demand that may result from climate change. Increases in industrial demand are not anticipated to substantially affect CMWD demands because industrial use is currently low and projected to remain low. Further, the majority of the projected increase in industrial water demands will be met with recycled water. While there may be limitations to CWMD’s ability to further conserve, CMWD is on track to meeting its SBx7-7 2020 target, achieved through a combination of conservation and increased recycled water use. CMWD’s efforts to improve supply reliability will help them meet summer demands, and in a normal year, supply is anticipated to exceed demands, providing a buffer for unexpected increases in demand that may result from climate change. Solar and wind power used at CMWD’s off-grid Santa Fe II facility June 2016 4-8 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final 4.2 Projected Water Demands This section presents CMWD’s projected potable water use, in five-year intervals, from 2020 through 2040. Projected water use consists of projected water used by CMWD, projected water sold to others, and additional projected water uses and losses. Table 4-4 shows projected potable and recycled water demands. CMWD’s demand projections presented in this section meet CMWD’s gpcd demand targets that are described in Section 5 Baselines and Targets. SDCWA currently provides all of the potable water distributed by CMWD. The projected amount of water that CMWD expects to purchase from SDCWA to meet water demands in the future is considered in Section 6 System Supplies. CMWD’s projections of future wholesale water that will be supplied by SDCWA do not entirely align with the projections developed by SDCWA in their 2015 UWMP, but are relatively similar. These differences are a result of different methodologies and assumptions used to develop the water demand projections. Water use and production records, combined with population, employment, and urban development projections, provide the basis for estimating future water supply requirements. The population projections presented in Section 3 System Description already incorporate land use changes and other local economic and demographic factors, and provide an appropriate basis for demand projection calculations. SDCWA’s demand forecast model was used to determine CMWD’s baseline water demands and projected active and passive conservation. SDCWA’s model incorporates land use and population projections generated by SANDAG for water agency service areas in San Diego County, and utilizes the Series 13 Growth Forecast model developed specifically for the San Diego region (including CMWD’s service area). The Series 13 model incorporates land uses and historical growth to project population growth in the future. A description of the demand forecast methodology is provided in SDCWA’s 2015 UWMP. SDCWA’s baseline demand projections for CMWD’s service area includes both potable and recycled water. To determine projected potable water demands, CMWD took the baseline and removed projected active/passive conservation and projected recycled water use (see Table 4-4). Although CMWD’s SBx7-7 target allows potable water use to be as high as 207 gpcd from 2020 into the future (refer to Section 5 Baselines and Targets), CMWD projects a lower per-capita water use as a result of the area’s growing conservation ethic and the increased use of recycled water to offset potable demands. Figure 4-2 shows the share of total demands that will be met by potable supplies and those met by recycled supplies. In addition to the projected demands, CMWD applied four scenarios to its water projections for purposes of comparison. These scenarios used the five-year, ten-year, and fifteen-year historical average water use, as well as CMWD’s SBx7-7 targets, and applied these to the projected populations. These scenarios are also presented in Figure 4-2. The fifteen-year and five-year scenarios were found to be unrealistic due to exceeding the maximum allowable water use or reflecting depressed demands from extraordinary conservation, respectively. Both the ten-year average scenario, which reflects some recent water savings as well as normal water years, and the SBx7-7 target scenario, which reflects CMWD’s legal maximum potable water use, were considered reasonable water demands. CWMD has elected to use SDCWA’s forecast for consistency with its wholesale water supplier and to allow for a consistent supply reliability analysis.

To project water use, CMWD developed an analysis based on projected land use from SANDAG’s Series 13 Growth Forecast. SANDAG land use data were available for 2012, 2015, and every 5 years to 2050. To allow for consistency between the water use and land use data, SANDAG land use categories were reconciled with CMWD’s water use billing categories by consolidating categories as shown in Table 4-5. Table 4-5: Reconciliation of CMWD Water Billing Categories and SANDAG Land Uses Reconciled Categories CMWD Water Billing Category1 SANDAG Land Use Type2 Agricultural Agricultural Agricultural Commercial Commercial Commercial Mixed Use Office Industrial Industrial Industrial Institutional Institutional Fire Protection School Military Irrigation Irrigation Roads Parks Multi-Family Multi-Family Multi-Family Mobile Home Other3 Single Family Single Family Temporary Potable Meters Low Density Single Family Single Family 1 Water Use Category based on CMWD billing categories 2 Land Use Types grouped into water use categories based on information from SANDAG regarding land uses categorized under each type 3 “Other” land use includes group housing To project water use by category, a “water use unit factor” was calculated that estimated a volume of water used for each acre of land use type. For purposes of this analysis, 2012 water use data were used as representative of a normal water year, because it reflects CMWD’s anticipated level of water use when mandatory water use restrictions are not in place. 2012 actual water use was calibrated to CMWD’s total water use projection methodology by scaling up actual 2012 water use (which was equivalent to a gpcd of 173) proportionally by use type as follows: % 2012 Actual Use x 2012 Water Use Calculated Using SBx7-7 Method = 2012 Water Use Proxy For example, Agriculture used 368 AF water, or 2% of total potable water use for 2012. Using the SBx7- 7 Demand Projection, the interim target of 233 gpcd, and the 2012 population of 82,748 people, total demand in 2012 would have been calculated as 21,597 AF. Agricultural demand was therefore calibrated as 2% of 21,597, or 398 AF, for the 2012 Proxy for agriculture. For each use type, the 2012 Proxy water use was divided by the land use to get a water use unit factor in AF per acre (AF/AC). For Agriculture, this was 0.71 AF/AC. Projecting forward, this unit factor was applied to the projected acreage for each land use type. Recycled water was then added, and water losses accounted for. The FY2015 AWWA water audit completed for CMWD indicated 4.7% of water produced was lost, calculated as the volume of water loss (real + apparent losses) divided by the volume of total water produced (water supplied). Limited discrepancies were reconciled proportionally June 2016 4-11 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final across water use type. The estimated projected water use by sector for 2020 through 2040 is presented in Table 4-6.

Water loss was calculated as 4.7% of potable water use (water loss divided by water production), based on FY2015 AWWA water audit for CMWD's potable system. Some differences may occur due to rounding. 4.3 Projected Total Water Use and Demand Projection Provided to Wholesaler Table 4-7 provides a summary of the total projected potable and recycled water use for CMWD, including retail water deliveries and additional water uses and losses for a normal or average year. SDCWA is projecting higher demands in dry years (SDCWA, 2016). CMWD’s water demands would be higher in dry years similar in proportion to SDCWA projections. Estimated changes in demand resulting from single or multiple dry years are provided in Section 7 Water Supply Reliability Assessment. Table 4-7: Current and Projected Total Water Demands (AFY) DWR Table 4-3 Retail: Total Water Demands 2015 2020 2025 2030 2035 2040 Potable Water 14,029 18,007 19,177 19,465 19,744 19,768 Recycled Water 3,793 5,078 5,078 5,078 5,078 5,078 Total Water Demand 17,822 23,085 24,255 24,543 24,822 24,846 NOTES: Recycled Water Demands are discussed in Section 6 System Supplies SDCWA currently provides 100% of the potable water distributed by CMWD, and CMWD does not receive raw water from any of its supply sources. CMWD’s Board approved an agreement for CMWD to purchase desalinated seawater from the Carlsbad Desalination Plant as part of its local supplies. These supplies are anticipated to begin deliveries in 2016. Therefore, CMWD’s projected demands on June 2016 4-12 2015 Urban Water Management Plan System Water Use Carlsbad Municipal Water District Final imported SDCWA potable water are equal to the total potable water demands presented in Table 4-6, less the 2,500 AFY desalinated seawater local supply. 4.4 Water Demands for Lower Income Households CMWD does not keep direct records of which customers are low income households, but an estimate of low income water use and projected demands has been developed based on estimated household incomes for the City of Carlsbad. DWR has defined a low-income household as one with a median household income (MHI) of less than 80% of statewide MHI. According to 2009-2013 American Community Survey, low income households are those earning $48,875 or less per year. The City of Carlsbad’s General Plan does not include data on number of low income housing units currently present within the City. CMWD therefore used SANDAG projections of household incomes to estimate the number of Low Income households it serves. Using the Series 13 Growth Forecast, which was developed based on general plans and anticipated development for cities within San Diego County, SANDAG developed projections of household incomes in tiers of $15,000. This analysis assumes that any household earning less than $45,000 annually qualifies as low income now and into the future. Within the City of Carlsbad, this translates to 23% of households, or 9,777 households. Applying the proportion of the City of Carlsbad residing in CMWD’s service area (77.6%) to this number results in an estimated 7,587 low income households in 2015. The proportion of households designated as low income with this analysis was then applied to projected residential demands to estimate low income water demands. This estimate assume that the ratio of low-income multi-family and single-family homes is consistent with the overall ratio of multi-family and single-family customers. Table 4-8 presents the projected low income water demands. The residential water demands presented in Table 4-1 and 4-6 include the water demands of low income housing as required by SB 1087. Table 4-8: Projected Water Demands of Low-Income Households Low Income Water Demands 2015 2020 2025 2030 2035 2040 Low Income Households 7,587 8,058 7,970 7,659 7,461 7,207 Low Income Single-Family Demands (AFY) 2,176 2,118 2,187 2,113 2,101 2,017 Low Income Multi-Family Demands (AFY) 468 477 490 472 449 431 Total (AFY) 2,644 2,595 2,677 2,585 2,550 2,448 June 2016 5-1 Baselines and Targets The Water Conservation Act of 2009 (also known as Senate Bill x7-7 [SBx7-7]) was signed into law in November 2009 as part of a comprehensive water legislation package. SBx7-7 sets a goal of achieving a 20% reduction in urban per capita water use statewide by 2020. DWR developed technical methodologies to guide the consistent development by urban water suppliers of their baseline per capita water use and targets. These baselines and targets were first reported in the 2010 UWMPs. 5.1 Overview of Baselines and Targets Calculations SBx7-7 requires urban water suppliers to establish per capita water use targets by using one of four methods: Method 1: A per capita water use by 2020 that is 80% of the urban retail water supplier’s baseline per capita daily water use using a 10-year average ending no earlier than December 31, 2004, and no later than December 31, 2010. Since CMWD’s recycled water comprised more than 10% of 2008 retail water delivery, a 10- to 15-year baseline period can be used that ends no earlier than December 31, 2004 and no later than December 31, 2010. As described below, a 10-year baseline period from 1999-2008 was selected, resulting in a baseline of 259 gallons per capita per day (gpcd). The resulting per capita demand target for 2020 is 207 gpcd, with an interim 2015 target of 233 gpcd. Method 2: The per capita daily water use estimated using the sum of several defined performance standards. This method requires quantifying the landscaped area and the baseline commercial, industrial, and institutional (CII) use. Method 2 was not calculated during development of this 2015 UWMP. Method 3: The 2020 water use target is calculated as 95% of the applicable state hydrologic region target, as set forth in the 2015 UWMP Guidebook (DWR, 2016). CMWD, located in DWR’s South Coast Hydrologic Region Number 4, has a year 2020 target of 95% of 149 gpcd, which is 142 gpcd. Method 4: A provisional method that was developed by DWR where the target is based on indoor residential, CII, outdoor, and water loss components. Using the Provisional Method 4 Target Calculator provided by DWR with a CII water use in 1997 of 3,241 acre feet (AF), Method 4 establishes a target of 207 gpcd. An urban water supplier must select one of the methods to set their per capita water use target. Water suppliers may choose to change the selected method until 2015. CMWD has selected Method 1 for establishing the 2020 per capita water use target of 207 gpcd. In January 2014, the Governor of California declared a State of Emergency, directing state officials to take all necessary actions to prepare for drought conditions. This declaration requested that all Californians reduce water consumption and that local water suppliers implement local water shortage contingency plans. With the continuation of the drought, in April 2015, the Governor issued an executive order (Executive Order B-29-15) to impose mandatory water use restrictions, including an order for CMWD to reduce potable water use by 28%. On February 2, 2016, the emergency drought regulations were revised and extended through October 2016. These revisions adjusted agency reduction targets to reflect local supplies and conservation efforts. As a result, CMWD’s mandatory reduction target dropped from 28% to 20%. Due to the current multi-year drought, CMWD is in a stage two “Drought June 2016 5-2 2015 Urban Water Management Plan Baselines and Targets Carlsbad Municipal Water District Final Alert,” which implements mandatory water restrictions such as restricted irrigation watering days and times. This level of reduction has reduced CMWD’s water use below its 2020 target. Since 2007, CMWD’s per capita water use has been experiencing a decline partially due to increased retail water cost, increased use of water conservation measures by customers responding to drought conditions, and poor economic conditions. CMWD’s per capita water use in 2015 (149 gpcd) was already below the 2020 target. This 2015 water use may be temporary as a result of conservation efforts to meet State-mandated demand reductions in response to the current unprecedented drought. A partial rebound to prior per capita water use levels may occur once the drought is over, although water use has met or exceeded its SBX7-7 targets. CMWD’s approach to meeting the 2020 per capita water use target has several elements consisting of increased saturation into the customer base of low flow plumbing devices and fixtures, continued implementation of demand management measures, water use reductions that occur with the increased costs of water, and increased use of recycled water. Recycled water is excluded from gross water use in determining per capita water use according to the DWR guidance. CMWD’s water conservation efforts are described in Section 6 Demand Management Measures. 5.2 Water Use and SBx7-7 Compliance CMWD’s gross water use is the total volume of potable water entering its distribution system. Only gross potable water use is used for SBx7-7 compliance. All required tables for calculating and demonstrating SBx7-7 compliance are provided in Appendix G. As directed by DWR, the 2015 UWMP is an opportunity to revise the SBx7-7 baselines and targets, and allows agencies to use finalized 2010 U.S. Census data for its population estimates for baseline years. CMWD has updated its population estimates for 2000-2010, and subsequently revised its baseline water use and targets, as described below. 5.2.1 Baseline GPCD Water Use Baseline gpcd water use was calculated using Method 1. This method requires calculating gpcd for each of the potential baseline periods, using updated U.S. Census population estimates for the years 2001-2010. Census data for 2000 and 2010 were overlaid with the CMWD service area, and an analysis was completed at the block-level to calculate the population served by CMWD in those years. For Census blocks that are partially within the CMWD service area, a proportion of the population equal to the proportion of the geographical area within the service area was used. The resulting population numbers were then compared to the U.S. Census population for the City of Carlsbad, and it was determined that on average, CMWD serves 77.6% of the total City’s population. This proportion was then applied to California Department of Finance (DOF) population estimates for the City of Carlsbad to provide an estimate of CMWD population in non-Census years. Using the population analysis results and water use data, the annual gpcd was determined for each year between 1990 and 2010. Table 5-1 presents the annual gpcd for each potential baseline year.

No adjustments were made to the 1990-2010 water use data from the 2010 UWMP because they are actual gross potable water use for CMWD’s system. The baseline period for CMWD was selected after consideration of all potential baselines periods. In accordance with the 2015 UWMP Guidebook, agencies meeting at least 10% of total water deliveries with recycled water in 2008 can use a 10- to 15-year baseline. CMWD’s recycled water deliveries in 2008 were 3,877 AF, or 15.9% of its total water deliveries of 24,460 AF. CMWD can therefore use a baseline consisting of a 10- to 15-year continuous period ending between December 31, 2004, and December 31, 2010. The potential baselines in Table 5-2 are presented by ending year. For a 10-year baseline ending in 2004, the starting year would be 1995; for the 15-year baseline ending in 2004, the starting year is 1990.

As shown in Table 5-1, during this baseline period, gross potable water use ranged between 17,313 AF in 1999 to a high of 22,099 AF in 2007. The average gross potable water use during the baseline period was 20,289 AFY. Population grew from 60,154 people in 1999 to 79,400 people in 2008, a growth of over 19,000 people over ten years. 5.2.3 SBx7-7 Baseline and Targets Using Method 1, which calculates the 2020 Target as 80% of the baseline per capita water use, CMWD’s water use target for 2020 is 207 gpcd, or a reduction of 52 gpcd. The interim target for CMWD water use, to be achieved by 2015, was calculated as the midpoint between the selected baseline and the 2020 target water use (233 gpcd). A 5-year baseline from 2003 to 2007 had an average water use of 255 gpcd, and was used to confirm the 2020 target was reasonable. Table 5-3 provides a summary of the baseline and targets for CMWD. The revised baseline and targets are preferred for inclusion in this 2015 UWMP because they represent a more accurate estimate of water use in CMWD’s service areas during the selected baseline period. While these revisions provide a minimally higher SBx7-7 target, which provides for some flexibility should growth occur at a different rate than is projected in the 2015 UWMP, it does not substantially affect CMWD conservation planning or implementation activities.

June 2016 6-1 Water Supplies This section discusses CMWD's sources of water supply, new supply opportunities, exchanges and transfers of water, wastewater and recycled water opportunities, projected water supplies, and climate change impacts to water supply. 6.1 Summary of Existing and Planned Water Sources CMWD’s existing water sources include a local supply of recycled water and purchased SDCWA water. All of CMWD’s potable demands are currently met with imported purchased through SDCWA. CMWD’s planned supplies include recycled water from the Phase III Recycled Water Project and desalinated seawater, along with continued purchases from SDCWA and groundwater. The Phase III Recycled Water Project will expand CMWD’s existing recycled water system and increase recycled water production and delivery. The Phase III Recycled Water Project is currently being implemented, with construction of multiple pipeline segments and the Carlsbad WRF expansion underway. Beginning in late 2015, desalinated seawater water made available via the Carlsbad Desalination Plant has been blended into the treated water purchased from SDCWA. Under an agreement with SDCWA, CMWD plans on constructing its own direct connection to the desalination pipeline on Lionshead Avenue, which will consist of the Carlsbad 5 Flow Control Facility and Pressure Reducing Station. Groundwater was used historically as a primary source of supply to Carlsbad. The groundwater quality was high in TDS compared to imported water supplies. Therefore, well production was subsequently discontinued after CMWD delivered imported water to the distribution system. However, the cost of imported water has increased substantially in the last ten years, making the local groundwater a viable local supply for the future even considering advanced treatment such as reverse osmosis. A detailed summary of CMWD’s projected supplies is provided in Section 6.9 Projected Water Supplies, while an overview of CMWD’s supplies are provided in Table 6-1.

Imported water is conveyed into the area via MWD and SDCWA aqueducts. Upon its formation in 1954, CMWD joined SDCWA to acquire the right to purchase and distribute imported water throughout its service area. SDCWA has 24 member agencies, including CMWD, and is the regional wholesaler of imported water in San Diego County. Beginning in 2016, CWMD will begin receiving direct deliveries of desalinated seawater, reducing CMWD’s reliance on SDCWA for potable supplies (see Section 6.5 Seawater Desalination). CMWD also purchases disinfected tertiary recycled water from VWD and LWWD to help meet recycled water demands for customers remote from the Carlsbad WRF. Discussion of these recycled water suppliers are provided in Section 6.7 Wastewater and Recycled Water Opportunities. 6.2.1 Metropolitan Water District of Southern California MWD was created in 1928 following the passage of the Metropolitan Water District Act by the California Legislature to provide supplemental water for cities and communities on the south coastal plain of California. MWD serves as a water wholesaler, and provides water to its member agencies from both the Colorado River and the SWP. It has 26 member agencies including SDCWA, and covers an area which includes all, or portions, of Ventura, Los Angeles, Orange, Riverside, San Bernardino, and San Diego Counties. MWD’s water supplies and management programs are discussed in their 2015 Regional Urban Water Management Plan (MWD, 2016). 6.2.2 San Diego County Water Authority (SDCWA) SDCWA was organized on June 9, 1944 under the County Water Authority Act for the express purpose of importing Colorado River water into San Diego County. SDCWA annexed to MWD in 1946. As its largest customer, SDCWA is now represented on MWD’s Board of Directors by four directors. SDCWA purchases water from MWD and other sources for resale to its 24 member agencies. Beginning at the end of 2015, SDCWA’s potable supplies have included a mix of imported water, local surface water, and desalinated seawater from the Carlsbad Desalination Plant. 3-CMWD is one of 24 member agencies of SDCWA. Each member agency is autonomous and represented on SDCWA’s Board of Directors, setting local policies and water pricing structures. The representatives on the Board of Directors are appointed by each member agency and the number of representatives for each agency is based on a ratio of each member’s assessed valuation compared to the total of all member agencies. CMWD currently has two Board members on the 36-member Board of Directors. Member agency status entitles CMWD to directly purchase water from SDCWA on a wholesale basis. CMWD also looks to SDCWA to ensure, to the best of its ability, that adequate amounts of imported water will be available to satisfy future potable water requirements. SDCWA’s water supplies and management programs are discussed in their 2015 Urban Water Management Plan (SDCWA, 2016). CMWD’s projected water purchases from SDCWA are provided in Table 6-13, below. June 2016 6-4 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final 6.3 Local Surface Water and Groundwater CMWD does not currently use any local groundwater and surface water supplies, although in the past both types of water sources have been used. Prior to 1957, the Carlsbad Mutual Water Company supplied local surface water from Lake Calavera and groundwater from the Mission Basin of the San Luis Rey River to the City of Carlsbad. In addition, the Terramar Water Company provided local groundwater to a portion of the City of Carlsbad from the Agua Hedionda subunit 4.30 of the Carlsbad hydrologic unit through wells they developed, referred to as the Cannon Well Field. In August 1957, the water rights and other assets of the Carlsbad Mutual Water Company and Terramar Water Company were purchased by the City of Carlsbad. In May 1983, through an agreement, these local surface water and groundwater rights were transferred to CMWD by the City of Carlsbad. This included rights to Mission Basin of the San Luis Rey River Valley of 200 miner’s inches (approximately 3,650 AFY) of groundwater, prescriptive rights of 5 cubic feet per second (cfs) (up to 2,382 AF) of groundwater, and/or pre-1914 appropriative rights The Carlsbad Mutual Water Company held a permit with the State Division of Water Rights for another 1,000 AF annually from the Mission Basin. The original permit was for irrigation purposes and was later changed to recreational and fire protection purposes. Additionally, there were surface water rights for 150 AFY which were held from Calavera Creek. The Terramar Water Company had rights to 450 AFY of groundwater from the Agua Hedionda Creek Basin. Finally, CMWD obtained a permit for surface water in the amount of 25 AF from Agua Hedionda Creek as a result of constructing Maerkle Dam in 1962 Table 6-2 identifies the groundwater basins in the vicinity of CMWD according to DWR Bulletin 118, which are also shown in Figure 6-1, above. The Batiquitos Lagoon Valley Groundwater Basin is the only basin located in CMWD’s service area. The San Luis Rey Valley Groundwater Basin is located north of CMWD and the San Marcos Valley Groundwater Basin is located east of CMWD. Of these groundwater basins, San Luis Rey Valley Groundwater Basin has been designated as a Medium Priority Basin under California Groundwater Elevation Monitoring (CASGEM), while both Batiquitos Lagoon Valley and San Marcos Valley Groundwater Basins are designated as Very Low Priority. High and Medium priority basins are required by the State to be monitored, while Low and Very Low priority basins are not currently considered basins of concern; as such, of the basins in the vicinity of CMWD’s service area, only monitoring of the San Luis Rey Valley Groundwater Basin is mandated. This monitoring is being undertaken through a coordinated effort between the City of Oceanside and the County of San Diego. None of the basins listed in Table 6-2 are adjudicated, nor has DWR identified any of these groundwater basins as being in overdraft. Within the San Luis Rey Valley Groundwater Basin are several locally-recognized subbasins, which are commonly considered separate hydrological units: Mission, Bonsall, Moosa, Pala, and Pauma Basins (SDCWA, 2010). Other potential sources of groundwater could be subsurface flows from local hydrologic areas within the Carlsbad Watershed, including Buena Vista Creek Basin, Agua Hedionda Creek Basin, Encinas Creek Basin, and the Batiquitos Hydrologic Subarea. These resources have low potential yields, poor quality, or no available data to substantiate their long term use in the public water supply. Generally speaking, these basins do not have geological characteristics or size comparable to the Mission Basin of the San Luis Rey Valley Groundwater Basin, and collectively could supply only a small portion of CMWD’s needs.

Groundwater management plans or groundwater sustainability plans would be adopted prior to use of these groundwater basins for supply, as required. Mission Basin Of the groundwater basins available to CMWD, the Mission Basin of the San Luis Rey Valley Groundwater Basin has the most potential as a viable water resource. This basin has a large drainage area of 565 square miles and consists of alluvium and river channel deposits averaging 150 feet in depth. The quality is mildly brackish with TDS concentrations ranging from 1,000 to 1,500 milligrams per liter (mg/L). For CMWD’s use, the water would need to be treated by a low pressure membrane, reverse osmosis process to achieve treated water quality in the range of 500 mg/L. The City of Oceanside is currently doing this at their Mission Basin Groundwater Purification Facility. In 2005, CMWD completed a study on the cost effectiveness of utilizing the groundwater from the Mission Basin. This study showed that while the treatment and delivery of groundwater is feasible, it was not cost effective for CMWD at the time of the study. As a result, CMWD’s Board approved the staff recommendation to discontinue efforts to utilize this groundwater source as an alternate local supply at that time. However, since 2005, improvements in technology may have resulted in lower costs for removing TDS, and these costs may continue to decrease over time. In addition, the cost of imported water has increased significantly since 2005 and this trend is projected by both MWD and SDCWA to continue over time. With the increasing cost and decreasing reliability of imported water, the cost effectiveness of using local groundwater once again has become attractive. A groundwater supply from the Mission Basin would require the construction of several wells, a groundwater treatment facility, and a conveyance system. Wheeling the treated groundwater through the Oceanside distribution system may be an option. Accordingly, CMWD currently is reevaluating its plans for utilization of groundwater in the Mission Basin, which may become cost effective, for CMWD or third parties, as technology continues to improve and imported water costs continue to increase. The 2012 Water Master Plan included capital improvement project funding in Phase 4 to develop groundwater supplies in both the Mission Basin and Agua Hedionda Creek Basin areas. June 2016 6-6 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final Cannon Well Field The Cannon Well Field, located within the Agua Hedionda Creek Basin subarea of the Carlsbad Watershed, was historically used as a source of local water. Pumping ceased after 1962, but in the years leading up to then, production ranged from 16 AFY to 238 AFY. This well field could be considered having a potential available yield of 450 AFY (CMWD, 2012). Historically, additional small private wells for individual residences were also located within this subarea, along with private wells in the Buena Vista Creek Basin (RWQCB, 1980). A 1991 study titled Report on the Feasibility for Development of the Cannon Well Field Carlsbad, California was completed of the Agua Hedionda subunit where the Cannon Well Field is located. This study indicated that by a 1950 agreement between then-landowner Ellen Hall and J.D. Cannon, the Terramar Water Company was granted the right to drill for and remove water from the land. In 1964, this original agreement was merged with an agreement with the City of Carlsbad and the then- landowner to have the sole right and exclusive right to drill wells on the property and take and remove all water developed on the property and deliver it to such places as the City, in its sole discretion, may determine. The City (CMWD) shall be entitled to produce from the property an additional 16.5 AFY; however, there are no recorded groundwater rights. The safe yield was estimated in the 1991 study at 400 AFY. CMWD could begin the process of developing the groundwater. The Rancho Carlsbad Mobile Home Park does have one operating well in the vicinity, estimated at 100 AFY, which they use to supply water for irrigation of their landscaping and through a separate agreement supply water to the adjacent Rancho Carlsbad Golf Course. Ultimately, if there is excessive pumping, there may be adverse effects, such as the elimination of surface flow in Agua Hedionda Creek, reduction in the wetlands area downstream of the El Camino Real Bridge, and increased salinity in the transition zone of fresh water to salt water in the Agua Hedionda Lagoon. These problems can be addressed if the Cannon Well Field is developed by CMWD through a program of scheduled observations and a monitoring program. CMWD is currently in the process of clarifying its groundwater rights. Groundwater could potentially be recovered from the Mission Basin and/or Agua Hedionda Lagoon, although such groundwater would require desalination. CMWD still is exploring groundwater as a local water supply concept; as such, groundwater is not included in CMWD’s supply projections. CMWD does not currently pump groundwater; therefore DWR Table 6-1 (Table 6-3) is not currently applicable. Table 6-3: Groundwater Volume Pumped DWR Table 6-1 Retail: Groundwater Volume Pumped Supplier does not pump groundwater. The supplier will not complete the table below. 6.4 Storm Water CMWD does not currently utilize storm water for supply, nor does it plan to beneficially use storm water as a resource in the near future. 6.5 Seawater Desalination Since 1999, a large-scale seawater desalination facility has been actively explored as a potential local supply for the San Diego region. CMWD was involved in planning for the seawater desalination facility throughout its development. After exploring the feasibility of a variety of purchase agreements and delivery structures, Poseidon Resources (Channelside), L.P. (Poseidon), SDCWA, and SDCWA’s member agencies came to agreement to move forward with implementation of a desalination facility June 2016 6-7 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final for the region. In 2015, Poseidon completed construction of the Carlsbad Desalination Plant, located at the Encina Power Plant site adjacent to Agua Hedionda Lagoon, and began deliveries of desalinated seawater. Desalinated water produced at this facility is designated a local supply. Desalinated water from this facility is pumped to SDCWA’s Twin Oaks Treatment Plant (refer to Figure 3-2), where it is blended with treated imported water for delivery to SDCWA member agencies, including CMWD. On April 12, 2016, CMWD Board of Directors approved an agreement between SDCWA and CMWD for the planning and design of the direct connection to the desalinated pipeline (Carlsbad 5 Flow Control Facility and Pressure Reducing Station), which will provide 2,500 AFY of local desalinated seawater to CMWD through a Take or Pay agreement. SDCWA currently purchases all of the water produced at the desalination facility under its purchase agreement with Poseidon. In addition to receiving desalinated seawater through SDCWA’s supply mix, CMWD also opted to maintain its rights to receive water directly from the desalinated pipeline coming from the facility. A direct connection would improve water supply reliability and add infrastructure redundancy by providing a delivery system independent of SDCWA’s larger system. Should supply disruption occur as a result of damage to SDCWA’s system, CMWD would still be able to receive desalinated seawater when the option to pursue a direct connection to the facility which will consist of Carlsbad 5 Flow Control Facility and Pressure Reducing Station is implemented. Through its general purchase of water supplies from SDCWA, CMWD receives a pro rata share of 1,449 AFY desalinated water, and CMWD will also directly receive an additional 2,500 AFY desalinated water as part of a Take or Pay agreement. This direct supply is considered a local supply for CMWD. In the event that additional water is produced by the Carlsbad Desalination Plant, beyond SDCWA’s annual demand commitment of 48,000 AFY, CMWD may purchase an additional volume of desalinated water, equal to 5.21% of the additional production. This additional water is not accounted for in current supply projections due to uncertainty surrounding its procurement. As shown in Table 6-4, the Carlsbad Seawater Desalination project and brackish groundwater from the San Luis Rey Valley provide opportunity for the development of desalinated water within CMWD’s service area as a future supply source. Table 6-4: Opportunities for Desalinated Water Sources of Water Opportunities Ocean water Carlsbad Seawater Desalination Project/Poseidon Resources Brackish groundwater Mission Basin of San Luis Rey Valley 6.6 Transfers and Exchange Opportunities CMWD relies entirely on water purchased from SDCWA for potable water supplies, and does not participate individually in any water transfer or exchange programs at this time. After completion of the Phase III Recycled Water Project, CMWD may provide recycled water via transfers or exchanges to other agencies in the future as part of the NSDWRC. 6.7 Wastewater and Recycled Water The City of Carlsbad provides wastewater services through its participation in EWA, while CMWD produces, buys, sells, and distributes recycled water to customers both within its service area and to customers located in adjacent agency service areas. This section describes wastewater and recycled water supplies and demands for customers within CMWD’s service area, as well as those served by CMWD but located outside of its direct service area. Table 6-5 provides a summary of recycled water June 2016 6-8 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final supply and demand, which are all further explained in detail below. CMWD’s supply projections are significantly higher than current identified demands because CMWD has the potential to retain its current purchasing rights from VWD and LWWD, but is also expanding its Carlsbad WRF to increase local production of recycled water. CMWD will either identify new non-potable customers or sell the recycled water to neighboring agencies to allow the region to maximize local sources. CMWD anticipates only producing as much recycled water at Carlsbad WRF to meet demands, but the potential surplus of recycled water allows for flexibility in management of its supplies, and provides potential for increasing recycled water use within and adjacent to CMWD’s service area, Table 6-5: Summary of CMWD’s Recycled Water Supplies and Demands (AFY) 2015 2020 2025 2030 2035 2040 Recycled Water Supplies Carlsbad WRF 1,9031 8,272 8,272 8,272 8,272 8,272 Meadowlark WRF 2,000 2,000 2,000 2,000 2,187 2,187 Gafner WRF 247 247 247 247 247 247 Total Recycled Water Supplies 4,150 10,519 10,519 10,519 10,706 10,706 Recycled Water Demands Projected Recycled Water Demands 3,793 5,078 5,078 5,078 5,078 5,078 Potential Recycled Water Surplus 357 5,441 5,441 5,441 5,628 5,628 1 Actual 2015 volume supplied. 6.7.1 Recycled Water Coordination For production and delivery of recycled water sufficient to meet local demands, CMWD’s recycled water system requires coordination with the three agencies listed here. CMWD’s relationship with each of these organizations is also described. Encina Wastewater Authority (EWA): Regional wastewater collection and treatment system; supplies secondary effluent to Carlsbad WRF for tertiary treatment and discharges unused secondary effluent to the Pacific Ocean via the Encina Ocean Outfall Vallecitos Water District (VWD): Produces tertiary recycled water and sells to CMWD Leucadia Wastewater District (LWWD): Produces tertiary recycled water and sells to CMWD 6.7.2 Wastewater Treatment and Collection Facilities EWA provides regional treatment and effluent disposal through an ocean outfall from the EWPCF. EWA is owned by six agencies in northern San Diego County, and operates under a joint powers agreement: Cities of Carlsbad, Vista, and Encinitas, VWD, Buena Sanitation District, and LWWD. In total, EWA provides wastewater services to approximately 300,000 people. Wastewater collected by EWA members are conveyed to the EWPCF, where it is treated to secondary, and either discharged to the Pacific Ocean via the Encina Ocean Outfall or conveyed to the Carlsbad WRF or Gafner WRF for additional treatment for beneficial reuse. The City of Carlsbad owns capacity rights at EWPCF for 10.26 mgd. The EWPCF provides for full secondary treatment, sludge handling, and disposal through a deep ocean outfall (Encina Ocean Outfall) that extends along the ocean floor to a point one and a half miles off shore, at a depth of over 150 feet. Treatment levels at EWPCF meet all current State and Federal requirements. Refer to Figure 6-1 for location of the EWPCF and Encina Ocean Outfall. June 2016 6-9 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final Within CMWD’s service area, wastewater collection is provided by the City of Carlsbad and LWWD. The City of Carlsbad’s sewer system includes 288 miles of pipeline within CMWD’s service area, and conveyed an average flow of 6.17 mgd for Fiscal Year 2015, a 4.6% increase over 2014 (EWA, 2015). LWWD provides wastewater services to the La Costa portion of CMWD’s service area, and operates approximately 200 miles of pipeline to serve 60,000 people in Carlsbad and neighboring Encina. LWWD’s flows to the EWPCF averaged 3.91 mgd in Fiscal Year 2015, a 4.2% decrease (EWA, 2015). All sewer flows are conveyed to the EWPCF for treatment. Table 6-6 identifies the wastewater collected within CMWD’s service area, while Table 6-7 identifies the volume of wastewater that is either recycled or discharged within CMWD’s service area. The wastewater amounts generated within CMWD boundary are estimated to be approximately five to ten percent greater than the City of Carlsbad’s sewer service area because it also includes a portion of LWWD’s sewer service area. Recycled water is presently supplied to CMWD from three sources consisting of a maximum allocation of 4.0 mgd from Carlsbad WRF, 3.0 mgd from Meadowlark WRF (owned by VWD) and 0.75 mgd from Gafner WRF (owned by LWWD). Meadowlark produces 2.7 mgd tertiary recycled water, or 3,632 AFY. Approximately 2,000 AFY of this tertiary recycled water is delivered to CMWD, while the remaining 1,600 AFY is delivered to Olivenhain Municipal Water District. All of the tertiary recycled water produced at the Gafner WRF is used by CMWD to support recycled water demands of the Omni La Costa Resort and Spa. On average, CMWD uses 247 AFY recycled water from the Gafner WRF, or approximately 0.2 mgd.

June 2016 6-12 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final Encina Water Pollution Control Facility The EWPCF is owned and operated by EWA, and currently treats an average flow over 20 mgd wastewater, but has the capacity to treat over 40 mgd. The EWPCF produces over 5.0 mgd of secondary treated recycled water. Treated secondary recycled water is used in the plant and reduces costs for potable water required to operate the facility. Additional effluent flows from the facility are diverted from the ocean outfall and transferred to Carlsbad WRF and Gafner WRF for further treatment. Secondary effluent that cannot be reused, either directly or through additional treatment to meet tertiary recycled water demands, is discharged through the Encina Ocean Outfall. Carlsbad Water Recycling Facility The Carlsbad WRF, owned by CMWD but operated by EWA staff, can currently be maximized at 4.0 mgd (4,480 AFY). Recent consumption report data shows an average of 4,225 AFY in combined recycled water deliveries in the past three years, with approximately 2,000 AFY from the Carlsbad WRF and the remaining from the Gafner and Meadowlark WRFs. This facility receives secondary treated water from the EWPCF for tertiary treatment. Through the implementation of the Phase III Recycled Water Project, the Carlsbad WRF will be expanded to 7.38 mgd (8,267 AFY) in the near-term, and 12 mgd (13,442 AFY) in the long-term, and is anticipated to help meet a 76% increase in recycled water demands. Gafner Water Recycling Facility The Gafner WRF is owned and operated by LWWD, and has a total capacity of 1.0 mgd (RWQCB, 2001). CMWD is permitted to purchase up to the entire 1.0 mgd (1,120 AFY) from the Gafner WRF, but in recent years CMWD has purchased an average of 247 AFY. These supplies are delivered to the La Costa Resort and Spa, in the southern portion of CMWD’s service area. CMWD’s supply projections continue to include 247 AFY from Gafner WRF, although future purchases are uncertain as Segment 8 of the Phase III Recycled Water Project is intended to serve the La Costa Resort and Spa. Meadowlark Water Reclamation Facility Meadowlark WRF is owned and operated by VWD, and has a total capacity of 5 mgd. CMWD’s rights to disinfected tertiary water from the Meadowlark WRF ranges from 2.0 mgd during the months of November through March and 3.0 mgd during the months of April through October and this equates to 2,989 AFY. The remaining amount of recycled water produced by the Meadowlark WRF can be sold to OMWD under an agreement up to a maximum of 1.0 mgd or 1,120 AFY. CMWD generally purchases approximately 2,000 AFY recycled water from Meadowlark WRF, although 2015 resulted in slightly lower purchases of only 1,643 AF. In 2015, Meadowlark produced a total of 3,673 AF recycled water. Carlsbad Recycled Water Facility (Carlsbad WRF) June 2016 6-13 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final 6.7.3 Recycled Water Master Plan CMWD completed an update to its Recycled Water Master Plan in January 2012. The Recycled Water Master Plan evaluates the existing recycled water system, demands, supplies, regulations, and future system expansions. Beginning in 1990, CMWD began implementation of recycled water within in service area. By 1995, CMWD served over 1,000 AFY of recycled water through the implementation of the recycled water system facilities of Phase I. CMWD began implementation of Phase II in 2000, which included the construction of the Carlsbad WRF and expansion of the Meadowlark WRF, improvements to Mahr reservoir, three new booster pump stations, and 24 miles of additional recycled water pipelines. CMWD is now in the process of implementing its Phase III Recycled Water Project, which is discussed in further detail in Section 6.8 Future Water Projects, below. 6.7.4 Recycled Water Use CMWD began serving recycled water in 1993. Since 1993, CMWD has constructed treatment facilities, pumping stations, reservoirs, and pipelines, and has adopted a mandatory use ordinance requiring developers to install recycled water distribution pipelines within their projects. Water recycling is provided by CMWD to developed areas within CMWD’s boundaries, which includes the majority of the City of Carlsbad’s boundary, with the exception of the southeast corner of the City, which is served by OMWD and VWD. As described above and identified in Table 6-12, recycled water is presently supplied to CMWD from three sources: Carlsbad WRF, Meadowlark WRF, and Gafner WRF. The maximum flow rate available to CMWD from each treatment facility varies. CMWD’s current recycled water system has approximately 80 miles of recycled water distribution pipelines, as shown in Figure 5-2. As of December 2015, this distribution system had 788 meters supplying 362 recycled use sites. With full implementation of the Phase III Recycled Water Project (see below), an additional 88 customers will be connected to CMWD’s recycled water distribution system. CMWD projects a total of 5,078 AFY recycled water demands beginning in 2020 and into the future. This includes only verifiable recycled water supplies, consistent with SDCWA’s demand projections, but does not include planned or conceptual recycled water projects. There is potential for future projects to expand recycled water demands and deliveries beyond this volume. As of December 2015, five of these customers had already been connected to the expanded system. The largest and/or most recognized customers currently served by recycled water include: La Costa Resort and Spa, Four Seasons Resort at Aviara Kemper Sports Management (Carlsbad Municipal Golf Course) Legoland of California Grand Pacific Palisades Hotel Karl Strauss Brewery The 150 HP Twin “D” Pump Station, which helps deliver recycled water to CMWD customers.

The 2010 UWMP projected recycled water use in 2015 would be 5,000 AFY. The difference is accounted for by delays in construction and implementation of the Phase III Recycled Water Project. Table 6-9 compares the projected recycled water use for 2015 (as projected in the 2010 UWMP) with actual metered recycled water use for 2015.

For purposes of comparison, recycled water deliveries in 2015 were consolidated into these two use types. 6.7.6 Methods to Encourage Recycled Water Use CMWD has actively pursued recycled water in its service area, and has implemented multiple mechanisms to encourage recycled water use. Some of these mechanisms include rate incentives, policies and ordinances, development of clear use guidelines, participation in regional trainings and certifications, and active participation in regional and local recycled water projects that include outreach and expand distribution systems. Table 6-10 provides a summary of the methods that have been used to encourage recycled water use within CMWD’s service area. In 2015, CMWD charged a rate of $3.53/unit, or approximately $1,538/AF for recycled water. This is lower than potable water rates for all customer classes and rate types except Tier 1 Single and Multi- Family Residential customers (who use between 0 and 5 units potable water per month), which each paid $3.35/unit potable water. Commercial and Non-Residential customers paid $4.05/unit potable June 2016 6-17 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final water, Agricultural customers paid $4.15/unit potable water, and Irrigation customers paid $4.44/unit potable water. Recycled water can be an attractive choice given potential savings between $0.48/unit and $0.91/unit for non-residential users compared to potable water. CMWD policy is that recycled water shall be used within the jurisdiction wherever its use is economically justified, financially and technically feasible, and consistent with legal requirements, preservation of public health, safety and welfare, and the environment. Since 1990, City policy requires that recycled water be used on all new land use developments proposed in the City of Carlsbad for all State-approved non-potable uses, if and when available. CMWD’s Recycled Water Master Plan was prepared in support of CMWD’s recycled water policy to define, encourage and develop the use of recycled water, and is required to be updated no less than every five years. The installation of dual irrigation systems and connections to recycled water sources is also required and subject to the conditions of CMWD’s Recycled Water Master Plan. CMWD has Cross Connection Control Technicians who review on-site irrigation systems to verify no cross connections have occurred between the potable and recycled water systems. In addition, reviews are made to eliminate overspray and nuisance problems. To date, no major problems have occurred. A quarterly report is submitted to the San Diego Regional Water Quality Control Board (RWQCB) on any field tests and observations. For businesses, cross connection tests are often performed at night to reduce impacts on their operations and customers. CMWD’s Engineering Standards – Volume 2: Potable and Recycled Water (CMWD, 2004) provide user guidelines that have been established by CMWD, in conjunction with the review by San Diego County Department of Environmental Health, which are intended to provide the basic parameters for the use of recycled water in landscape irrigation. Each year, SDCWA hosts a one-day certified course designed to provide irrigation supervisors with a basic understanding of recycled water. Completion of the Recycled Water Site Supervisor Training fulfills the training requirement as mandated by regulatory authorities. The class provides information to supervisors on the water recycling process, recycled water quality and safety issues, the duties and responsibilities of the supervisor, landscape irrigation fundamentals, maintenance and management, and cross connection control shut-down tests and inspections. Understanding similarities and differences between recycled and potable water is important to the successful operation of a recycled water system. City of Carlsbad Recycled Water Use Guidance Irrigate between 10:00 p.m. and 6:00 a.m. only. Irrigate to minimize run-off, pooling and ponding. Adjust spray heads to eliminate overspray onto areas not controlled by the user. Monitor and maintain the system to minimize equipment and material failure. Continually educate all maintenance personnel on the presence and allowable uses of recycled water. Gain prior approval by CMWD of all proposed changes and modifications to any private facilities. Conduct annual cross connection inspection. Designate an on-site supervisor, in writing, who is familiar with the plumbing system, basic concepts of backflow/cross connection protection and the specific requirements of a recycled water system.

These demands are ones that have already been awarded funding or are far enough along in the design and contracting process to be considered certain. The remaining demands of the Phase III Recycled Water Project are considered “planned” recycled water demands, and are not included in the recycled water projections in this UWMP. The Phase III project includes the following components, designed to meet the following demands. Note that some demands may have changed as the project is being implemented: Segment 1A – 99 AFY Segment 2 – 286 AFY Segment 4A – 554 AFY Segment 5 – 454 AFY Segment 7 – 114 AFY Segment 8 – 420 AFY Segment 9 – 91 AFY Segment 18 – 25 AFY Connection of Adjacent to Existing Users – 598 AFY Carlsbad WRF Expansion Additional Storage CMWD is also one of ten member agencies of the NSDWRC, which is cooperatively implementing a regional recycled water system to maximize recycled water use and implement potable reuse in northern San Diego County. CMWD’s portion of the NSDWRC Regional Project is the Phase III Recycled Water Project. Through the NSDWRC, CMWD may provide recycled water to other members, and may receive additional recycled water from other members, as necessary. Additional information about the NSDWRC and its recycled water project can be found at http://nsdwrc.org/. June 2016 6-19 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final CMWD may also pursue groundwater as a future supply, but potential groundwater supplies are still considered uncertain, and are not accounted for in Table 6-11, which summarizes future water supply projects and programs. Despite this uncertainty, CMWD anticipates that affirming its groundwater rights will lead to development of additional groundwater supplies, which will help to offset CMWD’s demands on SDCWA for potable water. This addition of groundwater to CMWD’s supply portfolio will strengthen its supply reliability and help reduce CMWD’s reliance on imported supplies. As noted previously, CMWD’s Board approved an agreement with SDCWA to develop a direct connection to the desalinated seawater pipeline. Development of this supply will involve implementation of the Carlsbad 5 Flow Control Facility and Pressure Reducing Station project, and will result in 2,500 AFY additional local potable water. Once constructed, CMWD will own and operate the Pressure Reducing Station component, while the flow control facility will be constructed in agreement with SDCWA. Further, CMWD can purchase an additional 5.21% of any desalinated seawater produced beyond the 48,000 AFY minimum volume produced for SDCWA, which will further increase CMWD’s share of desalinated seawater in its supply mix.

If the plant produces more desalinated water and SDCWA purchases more than the 48,000 AFY that it currently purchases, CMWD may receive an additional 5.21% of the additional amount available. Because of uncertainty regarding this water, it has been omitted from this table as an available volume, but included in total right for desalinated water purchased via SDCWA. Purchases from SDCWA are not limited by Total Right or Safe Yield. June 2016 6-23 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final 6.10 Energy Intensity of Supplies CMWD elected to estimate the energy intensity of its potable supplies, using Appendix O of the Guidebook. A technical memorandum and the applicable Appendix O tables have been included here as Appendix I. Water energy intensity (EI) is the total amount of energy expended on a per AF basis to take water from the location CMWD acquires it to the point of delivery. Thus, EI includes conveyance, extraction, treatment, placing water into and taking it from storage, and distribution. CMWD’s water EI only accounts for the water management processes occurring within its operational control; energy use associated with the extraction, treatment and conveyance of wholesale water to CMWD’s points of diversion is not included. Because CMWD receives it potable water from SDCWA, and this water is already treated prior to entering CMWD’s distribution system, energy demands for CMWD’s potable system are limited to the requirements for distribution and limited local storage. Using billing data for CMWD, designated as the “Water Department” on City of Carlsbad’s gas and electric bills, for calendar year 2015, CMWD’s total energy use was 218,818 kilowatt hours (kWh). During this same timeframe, CMWD received 14,321 AF of water from SDCWA that was placed in local storage or distributed to customers. Note that the water placed in storage during 2015 is excluded from gross water use reported elsewhere in this document. CMWD’s potable water system therefore has a local EI of 15.3 kWh/AF. Monthly energy demands vary greatly from month to month, depending on the length of time water remains in local storage, the level of demand (affecting pumping and storage levels), and the need to implement minor treatment or mixing to maintain potable quality. Figure 6-2 shows energy demands and water purchases from SDCWA over the course of 2015. Figure 6-2: Monthly 2015 Energy Use and SDCWA Purchases - 10,000 20,000 30,000 40,000 50,000 60,000 70,000 0 200 400 600 800 1000 1200 1400 1600 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Energy Use (kWh)SDCWA Purchases (AF)Total Water Delivery Energy Use in kWh June 2016 6-24 2015 Urban Water Management Plan Water Supplies Carlsbad Municipal Water District Final 6.11 Climate Change Impacts to Supply Climate change is a concern for CMWD and other agencies within the San Diego region. A summary of climate change vulnerabilities, impacts, and actions to address these impacts is provided in Section 3 System Description. While the exact effects of climate change are unknown, average temperatures will increase, weather events will be more intense and more frequent, and precipitation patterns will change. As with other agencies in the region, CMWD relies heavily on imported water purchased from SDCWA. These imported supplies come from the SWP and the Colorado River. SWP reliability is dependent on rainfall and snowpack, and the timing of snowmelt. Climate change will make snowpack less reliable, either through changes in amount of water stored in snowpack, or through changes to the timing of snowmelt (e.g., earlier melt means excess water is available when demands are low, and less water is available during warmer months when demands are higher). Extreme weather events could damage imported water infrastructure or could exacerbate drought conditions. As identified by the Climate Change Planning Study completed for the 2013 San Diego IRWM Plan, climate change is anticipated to result in up to a 25% decrease in supplies from the SWP, up to a 20% decrease in supplies from the Colorado River, totaling a 164,000 AFY average shortfall in imported supply for the San Diego Region. The Climate Change Vulnerability Analysis found that that this anticipated decrease in imported supply was the greatest concern for the region, and was given a “Very High Prioritization”. The vulnerabilities identified in the assessment may contribute to issues include a decrease in imported supply, a decrease in groundwater supply, sensitivity due to higher drought potential, and reduction in available supplies due to impacts from invasive species. Local supply development is anticipated to help mitigate climate change impacts by developing drought-proof supplies (e.g. recycled water), reducing potential supply disruptions from imported water, and reducing overall energy demands for providing water to customers. Table 6-14: Climate Change Vulnerability Assessment Vulnerability Question Justification Does a portion of the water supply in your region come from snowmelt? Imported supplies (SWP, Colorado River) come from snowmelt. Does part of your region rely on water diverted from the Delta, imported from the Colorado River, or imported from other climate-sensitive systems outside your region? Approximately 80% of the Region's supplies are imported. Does part of your region rely on coastal aquifers? Has salt intrusion been a problem in the past? Some brackish groundwater exists near the coast which limits the use of coastal aquifers. Has your region faced a drought in the past during which it failed to meet local water demands? Drought management plans had to be put into effect. Note that the Region has never failed to meet its customers’ demands since drought measures were put into place. Development of additional supplies may reduce the Region’s vulnerability to this issue. Does your region have invasive species management issues at your facilities, along conveyance structures, or in habitat areas? Invasive species include Quagga mussels, Arundo, and Tamarisk Source: RWMG, 2013. . June 2016 7-1 Water Supply Reliability As an agency entirely dependent on SDCWA for its potable water supplies and with limited diversification options for its local supply portfolio, CMWD is particularly concerned about water supply reliability. Although CMWD is improving supply reliability by increasing recycled water use, utilizing local desalinated seawater, and reducing imported water demands, and SDCWA has taken action to increase its supply portfolio and decrease dependence on water imported via MWD, there remain a number of threats to supply reliability within CMWD’s service area. 7.1 Constraints on Water Sources CMWD’s water supply is subject to some factors that could result in inconsistency of supply due to legal, environmental, water quality, or climatic factors. As noted throughout this 2015 UWMP, CMWD’s potable demands are entirely served with potable water purchased from SDCWA, and is subject to availability of and access to those supplies. A lack of supply diversity contributes to potential supply constraints. Table 7-1 provides a summary of potential threats to supply reliability for CMWD’s various sources of potable and non-potable water. Table 7-1: Constraints on Water Supplies Source Potential Constraint on Supply Imported Water1 Legal: Current supply from SWP is occasionally inconsistent due to legal and environmental decisions. Future supply may not be consistent due to delays in construction, legal rulings, or environmental decisions. Legal decisions regarding the Quantification Settlement Agreement could reduce supplies from the Colorado River. Climatic: Drought and climate change could result in reductions of imported water supply. Colorado River supply may be reduced due to extended drought period. Mandatory use restrictions during drought may affect ability to utilize supply, even if sufficient supplies are available. Desalinated Seawater No constraints identified at this time. Groundwater Legal: CMWD is continuing to explore their groundwater rights and determine ability to utilize groundwater. Water quality: The Mission Sub-Basin has high levels of total dissolve solids (TDS) and requires desalination for potable use. Other: Groundwater basins in the region have limited storage capacity. Recycled Water Cost: Cost of recycled water system expansion can be challenging to complete connections. 1 Refer to SDCWA’s 2015 UWMP for additional details regarding constraints on their supplies SDCWA Supply Constraints and Reliability Actions SDCWA’s primary supplies include a mix of imported water from various sources and desalinated seawater. As noted in Table 7-1, SDCWA supply constraints are primarily due to legal and climatic factors. Imported water from the SWP may be subject to restrictions during drought or specific times of year as a result of legal decisions to maintain minimum flows for environmental needs, or other June 2016 7-2 2015 Urban Water Management Plan Water Supply Reliability Carlsbad Municipal Water District Final legal agreements. In addition, flows from SWP may be constrained if a section of the system shuts down for repair, construction, or other reason. Imported Colorado River supplies are subject to the Quantification Settlement Agreement (QSA), which may change as a result of legal decisions. However, Colorado River supplies are considered substantially more secure than SWP supplies, and are not anticipated to be constrained in this manner. Colorado River supplies are higher in TDS than SWP water however, affecting SDCWA’s blended raw water quality. However, this does not affect CMWD’s access to SDCWA supplies because CMWD purchases treated water from SDCWA, not raw water. Drought may also reduce availability of imported water to SDCWA (and subsequently reduce SDCWA supply availability to CMWD). During recent years, SWP supplies have faced allocations in 2014 and 2015, and are anticipated to experience allocations in 2016. Allocations to SWP supplies are anticipated as long as the current drought is in effect. SDCWA has taken steps to diversify its water supply with alternative sources, as described in SDCWA’s 2015 UWMP. Such efforts include canal lining and the Carlsbad Desalination Plant (Carlsbad Desalination Plant). SDCWA’s canal lining project provides conserved water by preventing unplanned loss to incidental recharge. This conserved water is guaranteed for SDCWA under the terms of the canal lining project. SDCWA also enabled construction of the Carlsbad Desalination Plant by agreeing to a minimum annual purchase of recycled water from the facility. This increases supply reliability because it is a drought-proof local supply. SDCWA anticipates that desalinated seawater from the Carlsbad Desalination Plant will meet approximately 10% of the region’s potable water demands. The reduced availability of any one of SDCWA’s supply sources would be buffered because of the diversity of the supplies; the region’s wholesale supplies are not reliant on a single source. To replace or supplement an existing supply, SDCWA could take steps to increase development of transfers or distribution of seawater desalination. SDCWA’s 2015 UWMP should be consulted for details regarding their actions to ensure consistency of the wholesale water supply. While regional efforts to improve supply diversification, storage, and system redundancy have worked to reduce the impacts such allocations have on local access to supplies, there is potential that mandatory use restrictions (at a statewide level) will be enacted during severe drought. Such restrictions, including those put in place by the State in 2015, may not affect supply that the region has in storage, but could affect the region’s ability to utilize supplies. CMWD Local Supply Constraints and Reliability Actions CMWD’s reliance on SDCWA for potable supplies leaves it vulnerable to supply disruptions to SDCWA’s system. As a result, CMWD has taken steps to ensure a more consistent water supply by expanding its local supplies. CMWD has two sources of local supply (recycled water and desalinated seawater) and one potential source of local supply (groundwater). The only constraints on recycled water are capacity, connectivity, and the associated costs of providing additional connections. CMWD’s Phase III Recycled Water Project is currently expanding its tertiary recycled water production capacity, as well as expanding CMWD’s recycled water distribution system to reach additional customers. As part of the NSDWRC, CMWD is participating in a cooperative effort of ten north San Diego County water and wastewater agencies to maximize recycled water use and improve interconnectivity between their non-potable water systems. This effort will allow for additional flexibility in non-potable water system operation and increase recycled water efficiencies. To help defray the cost of expanding its recycled water services, CMWD has actively pursued additional funding programs to help cover costs of the Phase III Recycled Water Project. As of the end of 2015, CMWD had received grants from Proposition 84 and Proposition 1, as well as a low-interest loan through the Clean Water State Revolving Fund. June 2016 7-3 2015 Urban Water Management Plan Water Supply Reliability Carlsbad Municipal Water District Final While CMWD is currently receiving its desalinated seawater via SDCWA’s pipelines, CMWD is planning on constructing a direct connection to the desalinated seawater pipeline on Lionshead Ave. to provide a local, drought proof supply that would function independently of SDCWA’s distribution system. This would create redundancy in the potable distribution system that would increase reliability of water deliveries from a drought-proof, secure, supply. To further diversify its local supplies, CMWD is exploring use of its groundwater rights (refer to Section 6 System Supplies). Groundwater in the Mission Sub-basin is high in TDS, and would require desalination before use as a supply. The addition of groundwater to CMWD’s supply portfolio would reduce its reliance on SDCWA to meet potable demands. However, since CMWD is currently working on its groundwater rights and the potential available volume of groundwater supply is uncertain, it has been excluded from CMWD’s supply portfolio in this 2015 UWMP. In the event of a severe drought, CMWD could effectively implement temporary water use reduction measures as defined in the water shortage contingency plan to assist in ensuring reliability. Such use reduction measures have been implemented in recent years (2014 and 2015) and proven successful in helping CMWD reach its temporary state-mandated reduction target of 28% under the State’s Emergency Drought Restrictions issued in 2015. 7.2 Reliability by Type of Year The water supply available to CMWD is defined based on three water supply condition scenarios: average/normal water year, single- dry water year, and multiple-dry water years. The water supplies available to CMWD from SDCWA during single- and multiple-dry years are based on the historical dry periods presented in Table 7-2 and are defined in SDCWA’s 2015 UWMP. Both of CMWD’s quantified local supplies (desalinated seawater and recycled water) are considered drought-proof supplies whose availability are not affected by drought. CMWD has therefore aligned its water supply reliability analysis with SDCWA’s supply reliability assessment. Calavera Hills Pump Station (60 HP) June 2016 7-4 2015 Urban Water Management Plan Water Supply Reliability Carlsbad Municipal Water District Final Table 7-2: Basis of Water Year Data DWR Table 7-1 Retail: Basis of Water Year Data Year Type Base Year Available Supplies if Year Type Repeats % of Average Supply Average Year 1986-2015 100% Single-Dry Year 2014 100% Multiple-Dry Years 1st Year 2013 100% Multiple-Dry Years 2nd Year 2014 100% Multiple-Dry Years 3rd Year 2015 92% -100% NOTES: CMWD selected base years that aligned with SDCWA’s 2015 UWMP supply reliability assessment. The third year of a multiple-dry year scenario may result in deficits that must be met through extraordinary conservation or further expansion of the recycled water system. In years with supply reliability, additional purchases would be made from SDCWA to meet demands. As presented here, “% of Average Supply” indicates percent supply available to meet potable demands due to diversification and/or carryover storage. Although Table 7-2 identifies the percentage of available supply to meet demand, supply availability will vary by source because CMWD’s local supplies would not be affected by dry year conditions. Changes to supply availability cannot be applied equally across each source. Potable and recycled water demands are both considered in CMWD’s supply reliability assessment because recycled water use offsets potable demands, while shortages in recycled water supplies require supplementation with potable supplies. SDCWA’s 2015 UWMP projected overall demands would increase over time and across scenarios, with some variability depending on the time frame and hydrologic scenario. CMWD anticipates that its demands would generally increase in dry year scenarios consistent with SDCWA’s overall demand increases in corresponding scenarios. Due to uncertainty inherent to projecting demands during dry hydrologic conditions, CMWD’s demand projections increase over dry year scenarios at a consistent rate across time frames (2020, 2025, 2030, 2035, and 2040), calculated as the average increase presented in SDCWA’s 2015 UWMP. Table 7-3 identifies how CWMD’s demands are projected to change, as a percent of normal, for different scenarios. Although demands are projected to increase, SDCWA has the right to purchase additional water from MWD in years where local supplies are insufficient to meet demands. Per SDCWA’s purchase agreement with MWD, SDCWA has sufficient preferential rights to water from MWD to meet demands not met by other sources for most scenarios. However, there is a potential shortfall in 2035 and 2040 in the third year of the multiple-dry year scenario. In years where SDCWA shows reliability, CMWD anticipates being able to purchase enough water from SDCWA to meet potable demands that cannot be met with desalinated seawater.

A comparison of projected supplies against projected demands helps to identify potential reliability issues during each hydrologic year scenario identified in Table 7-2. As indicated in Table 7-3, demands will vary depending on the hydrologic conditions. During dry years, demands are projected to increase to varying degrees based on the prior year hydrologic conditions. Demand increases are projected consistently for potable and non-potable demands because they will primarily be driven by irrigation needs. Note that these demand projections do not assume implementation of CMWD’s Drought Response Plan with its mandatory conservation measures; demands are assumed to increase as climactic conditions get hotter and drier. However, as demonstrated in 2014 and 2015, implementation of the drought response stages will significantly reduce water use across CMWD’s service area and can be levied as necessary if a supply shortage is identified. Supply availability will also vary within each hydrologic scenario, as identified in Table 7-3. CMWD’s local supply availability (recycled water and desalinated seawater) will remain consistent with projected normal year supplies regardless of hydrologic scenario because they are both drought-proof supplies. Supply from SDCWA will vary depending on SDCWA’s supply mix and demands from its member agencies. CMWD only purchases enough water from SDCWA to meet potable demands that cannot be met with local supplies. Any increases in potable demand must therefore be met with increased purchases from SDCWA. Because demands are projected to increase during dry years, CMWD’s purchases from SDCWA would also increase in those years, to the extent available. CMWD has no long-term potable water storage, and only purchases as much potable water as necessary from SDCWA. As a result, no potable water surpluses are expected during any hydrologic scenario. As shown in Tables 7-6, 7-8, and 7-10, CMWD does anticipate a surplus in recycled water, due to the expanded Carlsbad WRF’s capacity. CMWD does not anticipate producing recycled water in excess of demand (unused secondary wastewater is discharged via the ocean outfall). However, the June 2016 7-6 2015 Urban Water Management Plan Water Supply Reliability Carlsbad Municipal Water District Final additional capacity provides flexibility for CMWD to identify additional recycled water customers or additional opportunities to sell recycled water to neighboring agencies. Because CMWD’s demand projections in various scenarios are consistent with SDCWA’s projections for member agency demands, and SDCWA has accounted for all member agency local supplies, SDCWA’s supply reliability analysis documents that regional water supplies are generally reliable. For CMWD, potable supply reliability is assumed for any year in which SDCWA projects sufficient supplies to meet demands. SDCWA projects a potential shortfall in the third year of a multiple-dry year scenario for 2035 and 2040, however, which results in a potential potable supply deficit for CMWD. In these years, CMWD could reduce demands through the use of extraordinary conservation measures as described in Section 8 Water Shortage Contingency Planning. CMWD may also identify additional recycled water customers to reduce potable water use through the service area. Table 7-4 summarizes the potential potable water deficit in this scenario. CMWD has demonstrated its ability to reduce potable demands in the event of a supply deficit, as shown by its 16% reduction in demands between 2012 (the most recent normal year) and 2015 (third year of a multiple-dry year scenario). The potential deficit may also spur new connections to recycled water to offset potable demands. No non-potable water deficits are projected under any scenario. Table 7-4: Potential Potable Water Deficit in Year 3 of Multiple-Dry Year Scenarios (AFY) Multiple-Dry Year: Year 3 2020 2025 2030 2035 2040 Potable Supply 20,924 22,284 22,618 22,125 21,128 Potable Demand 20,924 22,284 22,618 22,943 22,970 Potential Deficit 0 0 0 818 1,842 Extraordinary Conservation or Conversion to Recycled Water 0 0 0 818 1,842 Total Potable Demand 20,924 22,284 22,618 22,125 21,128 Supply Deficit 0 0 0 0 0 SDCWA’s supply reliability analysis is more conservative than CMWD’s analysis because it only included consideration of “verifiable” supplies, which are supplies that are sufficiently under development to be considered secure. Although CMWD’s verifiable local supplies only include a portion of the Phase III Recycled Water Project, CMWD considers the entire recycled water expansion in its supplies. CMWD considers SDCWA’s analysis as representing a “worst case” scenario. The analysis included here is conservative because it is based on SDCWA’s conservative assessment of its available supplies, and because CMWD anticipates groundwater supplies in the future that have not been incorporated in this 2015 UWMP. Table 7-5 shows the projected normal year supplies for CMWD’s service area, broken down by supply source, along with projected normal year demands for corresponding years. Table 7-6 compares the supply and demands for a normal year. During normal years, CMWD anticipates sufficient supplies to meet projected demands. The surplus shown in Table 7-6 results from the increased capacity of the Carlsbad WRF; however, it is anticipated that the Carlsbad WRF would only produce as much tertiary recycled water as required to meet demands and short-term storage needs. These normal year projections are consistent with the projections included in Chapter 4 System Demands and Chapter 6 System Supplies.

There is no surplus or deficit for potable supplies. 7.3.1 Single-Dry Year The single-dry year scenario, selected to align with SDCWA’s reliability assessment, was determined to be 2015. SDCWA anticipates that regional demands will increase by approximately 7% in a single- dry year. CMWD assumes that this demand increase is consistent across the planning horizon. SDCWA’s analysis, which included a conservative consideration of member agency local supplies, found that there were sufficient supplies to meet projected demands on SDCWA, even in the face of increased demand during a single-dry year. This increased demand would be met with increased purchases from MWD. As a result, CMWD has assumed that SDCWA will be able to meet 100% of CMWD’s needs that cannot be met by local supplies, as shown in Table 7-7. Similar to the normal year reliability assessment, the surplus shown in Table 7-8 is recycled water.

There is no surplus or deficit for potable supplies. 7.3.2 Multiple-Dry Year During a multiple-dry year scenario, the region experiences on-going dry hydrologic conditions, such as in a multi-year drought. SDCWA’s 2015 UWMP states that in a multiple-dry year scenario, water from carryover storage would be used to help address potential supply deficits. Similar to the single-dry year scenario, demands during a multiple-dry year scenario are projected to increase over normal. In each year of a multiple-dry year scenario demands are anticipate to increase by approximately 6% (year 1), 11% (year 2), and 16% (year 3). SDCWA concludes that there is sufficient local, imported, and carryover storage supplies to meet demands in each year of a multiple-dry year scenario for 2020 through 2030. However, there is potential for a deficit in the third year of a multiple-dry year in 2035 and 2040. This deficit is due to regional demand growth outpacing verifiable supply growth. Any deficit experienced by SDCWA would result in a deficit in available supplies to its member agencies, including CMWD. While SDCWA’s analysis was conservative, and only includes “verifiable” supplies, CMWD has elected to be consistent with SDCWA’s analysis. In the third year of a multiple-dry year scenario, SDCWA anticipates extraordinary conservation will be implemented by its member agencies. As in other hydrologic scenarios for CMWD, surplus would be realized for non-potable recycled water supplies only. Despite a potential overall surplus, extraordinary conservation and/or expansion of the recycled water system would be required in the third year of a multiple-dry year scenario in 2035 and 2040. CMWD projects additional recycled water demands that June 2016 7-9 2015 Urban Water Management Plan Water Supply Reliability Carlsbad Municipal Water District Final are not captured in the verifiable supplies used for the SDCWA purchase projections; some of the extraordinary conservation is therefore anticipated to be addressed through planned conversion to recycled water. As needed, CMWD will implement its Drought Response Plan (refer to Section 8 Water Shortage Contingency Plan). Additional conversion to recycled water and/or extraordinary conservation efforts would reduce CMWD’s demand (Table 7-9) and supplies would again be sufficient to meet demands (Table 7-10).

June 2016 8-1 Water Shortage Contingency Planning CMWD’s arid climate, limited local supplies, and growing population make water shortage planning an important component of supply management, especially in light of the current severe drought and the potential for increased frequency, intensity, and duration of droughts due to climate change. CMWD has adopted measures and plans to address water shortages, should supplies be more limited than demand. This section describes CMWD’s water shortage contingency plan, considers the potential impacts shortages could have on revenue and expenses, and summarizes CMWD’s planned response in the event of catastrophic supply loss. 8.1 Water Shortage Contingency Plan In 2009, CMWD’s Board of Directors (Carlsbad City Council) adopted the following ordinances: 1. Ordinance No. 44 – Drought Response Plan and Water Conservation Program (Drought Ordinance), which established CMWD’s current water conservation program and drought response levels. 2. Ordinance No. 46 – Watering Schedules, which revised Drought Response Levels 2 and 3. Complete copies of these ordinances are provided here as Appendix I and the contents of each is described in further detail below. The Drought Ordinance replaced a previous Ordinance No. 35, which had included the Urban Water Shortage Contingency Plan. Because CMWD is dependent upon SDCWA for its water supply, SDCWA’s 2015 UWMP should also be consulted for their water shortage contingency plan. Emergency response stage actions become effective when SDCWA declares that it is unable to provide sufficient water supplies to meet the ordinary demands and requirements of its member agencies to the extent that insufficient water would be available. When SDCWA announces its stage declaration, CMWD concurrently declares its corresponding stage. 8.1.1 Stages of Action The Drought Ordinance outlines CMWD’s four drought response stages, as shown in Table 8-1. These stages, and their prohibitions, are described below. Each level builds on the previous level(s), placing additional restrictions on water use. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-2 Table 8-1: CMWD Water Shortage Stages DWR Table 8-1 Retail: Stages of Water Shortage Contingency Plan Stage Percent Supply Reduction1 Water Supply Condition Level 1 - Drought Watch Condition 0-10% Reasonable probability that supplies will not meet demands Level 2 - Drought Watch Condition 11-20% Supplies will not be able to meet expected demands Level 3 - Drought Critical Condition 21-40% Supplies not meeting current demands Level 4 - Drought Emergency Condition above 40% Major failure of a supply, shortage, or distribution system 1 One stage in the Water Shortage Contingency Plan must address a water shortage of 50%. NOTES: A water shortage above 40% (including a 50% shortage) triggers Level 4 restrictions, which includes prohibition on outdoor water uses, and provides CMWD the authority to make further restrictions, as necessary, for non-compliant users, as well as for any CMWD customer should water supplies require. Drought Response Level 1 – Drought Watch A Level 1 Drought Watch condition may apply when SDCWA notifies its member agencies that a demand reduction of up to 10% is required to allow for adequate supplies to meet demands. CMWD’s Executive Manager shall declare the existence of Level 1 conditions, and Level 1 conservation practices shall be implemented. Drought Response Level 2 – Drought Alert A Level 2 Drought Alert condition may apply when SDCWA notifies its member agencies that a demand reduction of up to 20% is required due to drought conditions or other reduction in supplies. The CMWD Board of Directors will declare a Level 2 condition, at which point all water conservation measures under Level 1 must be adhered to, with the addition of Level 2 water use restrictions. Drought Response Level 3 – Drought Critical A Level 3 Drought Critical condition may apply when SDCWA notifies its member agencies that demand reductions of up to 40% are required due to drought or other reduction in supplies in order to have sufficient supplies for anticipated demands. The CMWD Board of Directors will declare a Level 3 condition, requiring the continuation of conservation measures under Level 1 and Level 2, and the implementation of Level 3 water use restrictions. Drought Response Level 4 – Drought Emergency A Level 4 Drought Emergency condition may apply when SDCWA declares a water shortage emergency and notifies its member agencies that demand reductions of more than 40% are required in order to maintain sufficient supplies for anticipated demands. The CMWD Board of Directors shall declare a Level 4 Drought Emergency in the manner and on the grounds provided in the California Water Code §350. With the declaration of a Level 4 drought response, all water conservation measures under Levels 1, 2, and 3 must be adhered to, with the addition of Level 4 mandatory conservation measures. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-3 8.1.2 Prohibitions, Consumption Reduction Methods, and Penalties CMWD’s water use restrictions and prohibitions are listed in Table 8-2. The stage in which each prohibition is implemented and whether a penalty for violation of the prohibition is indicated. Mandatory and voluntary prohibitions, consumption reduction methods, and penalties are presented in Tables 8-2, 8-3, and 8-4, respectively. Methods used to determine actual water use reductions are described below under Determining Water Use Reductions. The reduction in water use that would occur from each of the reduction methods has not been quantified, as it varies depending on drought stage, local hydrology, and customer behavior. As specific stages are implemented, CMWD would closely monitor projected supply availability and demand. Depending on these projections, the methods presented in Table 8-5 would be enacted and enforced to achieve the desired reductions in water use. Prohibitions CMWD prohibits water waste at all times, and increases water use restrictions with each Drought Response Level in the Drought Ordinance. A description of all prohibition and restrictions under all levels of drought responses are provided here. As stated above, each response level also includes the restrictions of all previous levels. Mandatory Restrictions and Prohibitions in Effect at all Times The following water waste prohibitions are in effect at all times for CMWD’s service area: Washing down impervious surfaces with potable water Water waste resulting from inefficient landscape irrigation Use a hand-held hose with a positive shut-off nozzle or bucket to water landscaped areas that are not irrigated by a landscape irrigation system Use re-circulated water to operate ornamental fountains Wash vehicles using a bucket or a hand-held hose with a positive shut-off nozzle or a mobile high pressure/low volume wash system Serve and refill water in restaurants only upon request Offer guests in hotels and motels the option of not laundering towels and linens daily Use recycled or non-potable water for construction purposes when available Single pass-through cooling systems as part of new water service connections will be prohibited. Non-recirculating systems in all new conveyer car wash and commercial laundry systems will also be prohibited Breaks, leaks, or other malfunctions in water user’s plumbing or distribution system resulting in excess use, loss, or escape of water must be repaired in a timely manner 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-4 Table 8-2: CWMD Water Use Restrictions at Each Drought Response Level DWR Table 8-2: Retail Only: Restrictions and Prohibitions on End Uses Stage Restrictions and Prohibitions on End Users Additional Explanation or Reference Penalty, Charge, or Enforcement? 1 Landscape -

The CMWD Board of Directors will suspend consideration of annexations to its service area and may establish a water allocation for property served by CMWD. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-6 Drought Response Level 4 – Drought Emergency With the declaration of a Level 4 Drought Emergency, all water conservation measures under Levels 1, 2, and 3 must be adhered to with the addition of the following mandatory conservation measures: Stop all landscape irrigation, except crops and landscape products of commercial growers and nurseries Repair all leaks within 24-hours of notification by CMWD CMWD may install a flow restricting device for services of up to one and one-half inch size and comparatively sized restrictors for larger services upon a prior determination that the customer has repeatedly violated the provision of Ordinance 44. Additionally, CMWD may establish a water allocation for property served by CMWD. Consumption Reduction Measures CMWD also implements consumption reduction measures to assist customers throughout its service area in reducing water use. These methods include rebate programs, public information and education programs and the suspension of additional water connections within its service area. CMWD’s consumption reduction measures are provided in Table 8-3. Table 8-3: Consumption Reduction Measures Implemented by CMWD DWR Table 8-3 Retail Only: Stages of WSCP - Consumption Reduction Methods Stage Consumption Reduction Methods by Water Supplier Additional Explanation or Reference All Stages Provide Rebates on Plumbing Fixtures and Devices All Stages Provide Rebates for Landscape Irrigation Efficiency All Stages Provide Rebates for Turf Replacement 1 Expand Public Information Campaign 3 Moratorium or Net Zero Demand Increase on New Connections 3 Other Suspension of consideration of annexations to CMWD service area 3 Other The Board of Directors may establish a water allocation for property in served by CMWD 4 Other The Board of Directors may establish a water allocation for property in served by CMWD Penalties When mandatory restrictions are in place, CMWD implements penalties for violations of the restrictions or prohibitions described above, as proscribed by The Drought Ordinance and Ordinance No. 46. Each day that a violation occurs is considered a separate offense and administrative fines may be levied for each violation. For the first violation, CMWD will verbally notice the fact of the violation. For the second violation, CMWD will provide a written notice to the customer of the violation. For the third violation, CMWD may install a flow restricting device of one gallon per minute capacity for services of up to one 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-7 and one-half inch size and comparatively sized restrictions for larger services upon a prior determination of multiple violations. Additionally, an administrative fine of $100 may be issued for the third violation. For a fourth violation within a one year period, CMWD may issue a $200 administrative fine. Additional violations exceeding the fourth violation within a one year period may result in a $500 administrative fine. Table 8-4 indicates the penalties for violation and at what stage they take effect. Table 8-4: CMWD Penalties for Use Restriction Violations Penalty Stage Trigger Warning letter All stages First Violation Notice of violation All stages Second Violation Flow restriction installed All stages Third Violation Administrative citations All stages Third Violation ($100) Fourth Violation ($200) Fifth or More Violation ($500) In lieu of administrative penalties as described above, when deemed appropriate and necessary, each violation may be prosecuted as a misdemeanor punishable by imprisonment for no more than thirty days or by a fine not to exceed $1,000, or by both. All customers who incur a penalty due to violation of the Drought Ordinance and Ordinance No. 46 have the right to appeal the penalty. 8.1.3 Determining Water Use Reductions Because all water received from SDCWA is metered and monitored, and all CMWD customers are metered and billed monthly using computerized equipment, data are collected on an on-going basis that can allow CMWD to determine actual water use reductions. Each customer or customer group can be evaluated for compliance with conservation requirements. Methods used by CMWD to determine actual reductions in water use are summarized in Table 8-5. Table 8-5: Methods for Measuring Water Use Reductions Method for Determining Actual Reduction Type and Quality of Data Expected Use normalized or average water use baseline to determine reductions Each customer will be given a schedule of monthly use targets based upon the required reduction compared to the base period usage. Usage over the amount allocated for any given month will result in the customer incurring penalty pricing for usage that month. Usage under that amount will be accumulated to possible offset over-usage in successive month period. More frequent review of production Water production is currently monitored on a real-time basis through CMWD’s SCADA system, and reviewed on a daily basis. More frequent meter reading at customer locations Customer meters are read on a monthly basis which would coincide with the monthly allocation periods. Customers are given information on how to read their meter and monitor their own usage. More frequent leak detection and repair Leak detection and repair is currently an active and ongoing O&M function, so no major changes would be expected. System audit The water system is currently audited on a monthly and annual basis, comparing metered deliveries from the SDCWA to metered deliveries to retail customers. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-8 Method for Determining Actual Reduction Type and Quality of Data Expected Automated sensors and telemetry CMWD has a SCADA system, which contains features to provide real-time monitoring and alarms communications to on-call operators for identify abnormalities in reservoir fill rates, draw-down rates, and pump function, which can be associated system leaks and other malfunctions that could result in water loss. Monitor utility actions All CMWD actions are monitored and reported in a comprehensive Activities Report provided to the Board of Directors on an annual basis. Other types of staff reports on CMWD activities are given at the two regular Board Meeting each month or on as needed basis by the Executive Manager. Penalties for customers If and when penalty pricing were implemented, the amount and frequency of penalties would be monitored by the City of Carlsbad’s computerized billing system and then reported to the management staff and to the Board of Directors on a monthly basis. 8.2 Description of Revenue and Expenditure Impacts In the event of a water emergency, the Drought Ordinance and Ordinance No. 46 would be activated to respond to the level of shortage. At that time, drought response stage actions would go into effect, and CMWD’s revenue is anticipated to decrease due to reduced water sales. The amount of decreased revenue would depend upon the response stage, and how long each stage is in effect. In the event that revenues are less than required to meet CMWD’s financial obligations as a result of a water shortage, the CMWD would draw from its operating reserves and then propose increasing water rates to appropriate levels for the Board’s consideration. The operating reserves are maintained at adequate levels to provide short-term operating capital in case of emergencies as well as provide for rate stabilization. Tables 8-6 and 8-7 present how different actions and conditions impact revenues and expenditures, as well as provides a summary of potential actions that could be taken to address these impacts. Table 8-6: Impacts to Revenues and Methods to Address Impact Potential Impacts to Revenues Action Anticipated Revenue Impact Rate adjustment No impact. This would be an administrative function to analyze rate structure options to offset potential losses in revenue associated with reduced sales. Change in quantity of sales Reduction in revenue expenses and associated reduction in quantity charge-based revenues generated to cover local O&M costs. Could be offset by a combination of budget reductions, expense deferrals, including some non-critical CIP projects, draws on rate stabilization and operating reserves, and rate adjustments. Potential Solutions for Revenue Decreases Action Anticipated Effects Reserve Fund This option would have no short-term impact on the rate payers or CMWD because there are currently sufficient funds in CMWD’s operating reserves. Change rate structure Minimal changes in rates could offset significant reductions in available water supplies. Reduce overhead Overhead, or local fixed O&M costs, can be reduced in the short and mid-term by deferring selected cash-funded CIP and major maintenance projects, other expenditure reductions and if needed, hiring freezes. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-9 Decrease capital expenditures Deferral of selected, non-critical replacement projects will have little or no impact on CMWD or its customers, and would only extend the duration of the master planned replacement schedule. Infrastructure for new development is funded by new development and progresses at the rate needed by new development projects. Revise planning estimates If supply reduction were long-term, CMWD would make commensurate adjustments to its CIP schedule, staffing levels and retail rate structures based upon lower retail sales. Impacts would be moderate and implemented over time. Table 8-7: Impacts to Expenditures and Methods to Address Impacts Potential Impacts to Expenditures Actions Potential Impacts Change in quantity of sales Sales reductions could be offset with rate and budget adjustments and moderate CIP deferrals. Increased staff/salaries/overtime No impacts. Existing staff would be re-assigned to perform functions required to implement and enforce consumption reduction methods and requirements. Increased costs of new supplies, transfers or exchanges SDCWA would secure new supplies whose cost would be melded into overall costs. Increased costs of wholesale water would be passed through to CMWD’s customers. Potential Solutions for Expenditure Impacts Action Anticipated Effects Reserve Fund No impacts. The Replacement Fund is sufficient, and exists for the very purposes anticipated in a supply shortage scenario. Change rate structure Given the mix of wholesale water and power expenditures, non-commodity revenues needed to cover local fixed costs, availability of reserves and the flexibility to adjust CIP expenditures, no short-term (1 to 2 year) impacts are anticipated, mid-term (3 years) impacts would be moderate, and long-term (beyond 3 years) impacts would be moderate and incremental. Reduce overhead In the short-term and mid-term, overhead or local costs can be reduced by deferring non-critical CIP and major maintenance expenditures. In the long-term, costs can be reduced by adjusting operational and staffing levels and retail water rate structures to incorporate the reality of lower retail water sales than previously anticipated. Decrease capital expenditures In the short-term, there could be a decrease in the level of expenditures for CMWD’s replacement program, or an interruption of expenditures. In the mid- to long-term, the retail rate structure and the prioritization schedule would be adjusted to ensure that projects critical to service and system reliability were implemented. Revise planning estimates If the reduced supply is determined to be a long-term condition, then commensurate adjustments would be incorporated into long-term staffing and water system facility requirements. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-10 8.3 Catastrophic Supply Interruption Plan CMWD’s supplies are at risk for a catastrophic interruption because of its reliance on imported water to meet potable demands. While CMWD and SDCWA are both striving to reduce this dependence on imported water (through development of local supplies and increased recycled water use), the risk still exists that supplies will be interrupted in the event of a natural or man-made disaster. Potential catastrophes to which CMWD’s supplies may be vulnerable include, but may not be limited to: Earthquake Fire/explosion Medical Flood Tornado/severe weather Bomb threat Hard freeze Loss of normal water supply Hazardous material release Contamination of SDCWA or CMWD water supplies Terrorist attack The 125 HP Bressi Potable Water Pump Station CMWD has taken several actions for preparation for, and implementation during, a catastrophic interruption of water supplies. In the event of a supply interruption, CMWD’s defined command chain dispatches crews to inspect infrastructure and critical operations. Operations response crews are assigned to monitor system operations and modify operations as necessary, depending on the status of the system, the disaster, and needs. The defined communication command chain coordinates with other local water agencies and emergency response officials as necessary. Criteria and procedures are provided to return system to normal operations, including initiating water quality testing when necessary and performing necessary emergency repairs to the system. The emergency operations plan contains contact information for responsible parties and support services. Water shortage contingency plan stages will be implemented as required by the situation. 8.4 Minimum Supply Next Three Years CMWD’s potable supplies are currently purchased from SDCWA. The minimum available supply for CMWD is determined by SDCWA, based on SDCWA’s local supply projections, storage, and ability to access imported water, as well as CMWD’s local needs. Table 8-8 provides an estimate of the minimum water supply available from SDCWA during 2016, 2017, and 2018, assuming the same hydrology during the historical multiple-dry year period. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-11 Table 8-8: Minimum Potable Water Supply for 2016-2018 (AFY) DWR Table 8-4 Retail: Minimum Supply Next Three Years 2016 2017 2018 Available Water Supply 15,714 17,338 19,042 Notes: Assumes 2016, 2017, and 2018 are multiple-dry years 1, 2, and 3, with demand increasing over normal by 6%, 11%, and 16%, respectively. Normal year demands are assumed as a straight line projection between 2015 and 2020 to establish normal year demands for 2016, 2017, and 2017. 2015 Urban Water Management Plan Water Shortage Contingency Planning Carlsbad Municipal Water District Final June 2016 8-12 Page intentionally blank. June 2016 9-1 Demand Management Measures This section describes the past and current demand management measures (DMMs) undertaken by CMWD and quantifies, to the extent feasible, DMM efforts from 2010 through 2014 (the most recent years for which reporting is available). 9.1 Current Demand Management Measures CMWD currently implements a variety of DMMs to manage customer demands. Together, these DMMs have contributed to CMWD’s success in reaching its SBx7-7 Targets (refer to Section 5 Baselines and Targets) and contributed to a more conservation-literate population. 9.1.1 Water Waste Prevention Ordinances CMWD has two ordinances in place (both adopted in 2009) to prohibit water waste and encourage water use efficiency within the service area. The ordinances are updated as- needed in order to comply with State regulations and regional response to drought conditions. A short summary of these ordinances is provided here. For more details, refer to Section 8 Water Shortage Contingency Planning and Appendix I. 1. Ordinance No. 44 – Drought Response Plan and Water Conservation Program (Drought Ordinance) 2. Ordinance No. 46 – Watering Schedules CMWD also provides information on its website’s Water Rules page regarding any water use restrictions in place at a given time (http://www.carlsbadca.gov/services/depts/pw/utils/water/rules.asp). Drought Response Plan and Water Conservation Program (Drought Ordinance): The Drought Ordinance establishes ten water waste prohibitions in effect at all times, as well as four drought response levels that correspond to SDCWA’s drought management plan stages for signaling appropriate conservation use restrictions and targets. Table 9-1 provides a summary of the four drought response levels and Section 8 Water Shortage Contingency Plan includes a detailed discussion of the four levels. A copy of the full ordinance is included in Appendix I. UWMPs and the Water Conservation Act of 2009: Conservation requirements for the UWMP are based on the Water Conservation Act of 2009 (SBX7-7). This act mandates a 20% reduction in water use from average (based on 10-15 year baseline), measured in GPCD (gallons per capita per day, based on gross water use), by 2020, with an interim target of 10% reduction by 2015. For more information, refer to: http://www.water.ca.gov/urbanwatermanagement/u wmp2015.cfm 2015/2016 Emergency Regulations: Executive Order B-29-15 (April 2015; extended March 2016) imposed temporary mandatory conservation aimed at achieving 25% reduction statewide from 2013 levels during the current multi-year drought. Each water purveyor was assigned a conservation target by the state, measured in R-GCPD (residential gallons per capita per day, based on residential water use). CMWD’s initial conservation target was 28%, but was reduced to 20% due to regional supply development. For more information, refer to: http://www.waterboards.ca.gov/water_issues/progra ms/conservation_portal/emergency_regulation.shtml 2016 Extended Emergency Regulations: In May 2016, the SWRCP adopted new emergency regulations (applies June 2016 – January 2017) that would allow water purveyors to identify their own temporary conservation targets based on their ability to meet demands during continuation of multiple dry year conditions into 2017, 2018, and 2019. For more information refer to: http://www.waterboards.ca.gov/water_issues/progra ms/conservation_portal/emergency_regulation.shtml 2015 Urban Water Management Plan Demand Management Measures Carlsbad Municipal Water District Final June 2016 9-2 Table 9-1: Drought Response Levels Drought Response Condition Levels Use Restrictions Conservation Target Drought Management Plan Stage Level 1-Drought Watch Voluntary Up to 10% Stage 1 or 2 Level 2-Drought Alert Mandatory Up to 20% Stage 2 or 3 Level 3-Drought Critical Mandatory Up to 40% Stage 3 Level 4-Drought Emergency Mandatory Above 40% Stage 3 Watering Schedules: Ordinance No. 46 provides the authority for CMWD to set watering schedules when a drought response condition level is triggered, and provides a mechanism for appropriate public notification of any changes to watering schedules resulting from implementation of a drought response condition level. A copy of the ordinance is included in Appendix I. 9.1.2 Metering All of CMWD’s water connections are metered and billed according to water consumed. There are some mixed-use meters where irrigation and domestic use are metered through one service connection meter in CMWD’s service area. CMWD plans to convert those property’s irrigation systems to recycled water as the Phase III Recycled Water Project is constructed and the recycled water distribution system is extended. CMWD has a water meter replacement and calibration plan in place to ensure that meters are performing correctly and all water consumed is being recorded. In general, CMWD replaces meters under 1-inch every 20 years and meters over 1-inch every 15 years. 9.1.3 Conservation Pricing CMWD has and will continue to utilize a combination of uniform and increasing block or tiered rate conservation rate structures for potable water served. Single family and multifamily residential customer classes are billed in increasing block structures where the water rate increases for additional water units consumed. Table 9-2 shows the residential customer billing rates for 2015. Commercial, agricultural, and irrigation customer classes are billed using uniform rate structures where a flat rate is billed for every unit consumed. One unit is equal to a hundred cubic feet, or 748 gallons. Table 9-3 shows the 2015 billing rates for commercial customers. Recycled water was billed at a flat rate of $3.53 for all non-potable water customers in 2015. 2015 Urban Water Management Plan Demand Management Measures Carlsbad Municipal Water District Final June 2016 9-3 Table 9-2: 2015 Residential Customer Billing Rates for Potable Water Tier Block Structure Cost per Unit1 Single Family and Master-Metered2 Tier 1 0 – 10 units $3.35/unit Tier 2 11-18 units $4.45/unit Tier 3 19 units and above $6.42/unit Multiple Family2 Tier 1 0 – 5 units $3.35/unit Tier 2 6-10 units $4.45/unit Tier 3 11 units and above $6.42/unit 1 One water unit is 100 cubic feet or 748 gallons 2 Tiers are based on water use per dwelling unit, as measured in units of water consumed Table 9-3: 2015 Commercial Customer Billing Rates for Potable Water Tier Cost per Unit1 Agricultural rate $4.15/unit Irrigation rate $4.44/unit Commercial rate $6.42/unit 1 One water unit is 100 cubic feet or 748 gallons 9.1.4 Public Education and Outreach CMWD implements multiple approaches to public education and outreach on a variety of projects, initiatives, and goals. These approaches use outreach, workshops, school education programs, and provision of resources for CMWD customers. Many of CMWD’s efforts are implemented in coordination with other agencies and through regional efforts. Between 2010 and 2014, CMWD has dedicated over $3.6 million to support public education and outreach efforts. Outreach Activities CWMD staffs a water conservation booth dedicated to promoting water conservation at several events throughout the year. Displayed are handouts containing indoor and outdoor water saving information and conservation tools as free giveaways In order to reach a wide range of audiences, CMWD also makes brochures and handouts available at various community centers and City of Carlsbad and CMWD offices. Bill inserts are included with utility bills to announce available programs and important water conservation reminders. CMWD has consistently reached out to customers on at least a quarterly basis using various methods every quarter within the last five years. In coordination with SDCWA, CMWD promotes opportunities for residents to participate in regional programs such as Green Oceanside Business Network certification, California–Friendly landscape contest, Speaker Bureaus, and Citizens Water Academy. As a member of the NSDWRC, CMWD participates in outreach efforts educating the public on recycled water and potable reuse safety and use, and the importance of potable water conservation to the region. 2015 Urban Water Management Plan Demand Management Measures Carlsbad Municipal Water District Final June 2016 9-4 Workshops In coordination with SDCWA, CMWD provides workshops on water related themes geared to the residential user. Workshop topics presented in the past include California Friendly Landscape Training and Fix-a-Leak. Workshops are offered for free and held at different locations through the county, including within CMWD’s service area. School Education CMWD offers two school education programs for local schools as well as education materials to teachers upon request through SDCWA. The Splash Lab offers assembly presentations available to grades K – 6th to educate students on water science. For Grades 4 – 6, students can participate in a mobile water lab for a hands-on experience learning water related topics. Residential Customer Resources In coordination with MWD’s SoCal Water$mart program and SDCWA’s WaterSmart San Diego County program, rebates are available to CMWD customers to promote indoor and outdoor water conservation. One popular program that exhausted funds in 2015 was the turf removal rebate program designed to encourage the replacement of water thirsty turf for drought tolerant plants. These programs are advertised and linked to on CMWD’s water conservation website. Through SDCWA’s turf replacement rebate program, CMWD customers have converted 24,258 square feet of turf to water- wise landscaping, as of June 2015. Additional funds were recently secured by SDCWA to continue its turf conversion rebates, and it is anticipated that CMWD customers will continue to participate in turf conversions through this program. Table 9-4 provides a list of all rebates available and their associated rebate amounts. Table 9-4 Residential Water Conservation Rebate Rebate Program Name Rebate Amount Indoor Rebates Turf removal rebate $2/sq ft up to $6,000 Clothes washer rebate $135 HE toilets $100 Outdoor Rebates Turf removal rebate $2/sq ft up to $6,000 Irrigation controllers $80 Irrigation nozzles $4/nozzle - minimum is 15 Rain barrels $75 Soil moisture sensors $35/controller station Commercial Customer Resources In coordination with MWD’s SoCal Water$mart Program and SDCWA’s WaterSmart San Diego County program, CMWD provides information on available rebates for CMWD’s commercial customers that promote water efficiency for businesses.

In the past five years, approximately twelve water audits have been performed by CMWD staff and an independent contractor. WaterSmart Check-up Program CMWD has and will continue to offer the WaterSmart Check-up Program, in coordination with SDCWA, to top water users each month. During a WaterSmart check-up, a representative visits a property upon request to provide water saving tips and perform a water audit. This audit includes an inventory of water fixtures used indoors and outdoors, replacement of high use water fixtures, evaluating toilets for leaks, and performing a landscape water audit. During the water audit, sprinkler stations are turned on to evaluate inefficiencies and adjustments to watering schedules are made where appropriate. A summary report with additional conservation advertising is left with the customer at the end of the appointment. 9.1.5 Programs to Assess and Manage Distribution System Real Loss CMWD has completed the AWWA Water Loss Audit Software program and has determined that water losses are within the acceptable industry standard range. Water losses have been incorporated into the appropriate tables in Section 4 System Use. CMWD is proactive in reducing unaccounted for water 2015 Urban Water Management Plan Demand Management Measures Carlsbad Municipal Water District Final June 2016 9-6 by ensuring water meters are regularly maintained, evaluated for functionality, and replaced well within industry standards. Reported leaks are investigated and recorded in a tracking database that collects the time of report, leak location, and type of leaking pipe or fitting. Leaks are repaired to the extent that is cost effective and prioritized based on potential water loss. 9.1.6 Water Conservation Program Coordination and Staffing Support Water conservation staffing is performed by a full time (1 FTE) Water Conservation Specialist and a Supervisor at 25% time. The Water Conservation Specialist is responsible for developing, implementing, and monitoring water conservation programs and for conducting water audits. They are also responsible for promoting CMWD’s conservation programs. 9.2 DMM Activity CMWD is a signatory of the California Urban Water Conservation Council (CUWCC) and is in full compliance with the Memorandum of Understand. CMWD’s CUWCC reports for 2013 and 2014 are included in Appendix J for further details of compliance status. A summary of the extent of the BMPs implemented by CMWD from 2010 through 2014, along with a summary of continued and planned BMPs, is presented in Table 9-6, organized by CUWCC Best Management Practice (BMP). 2015 Urban Water Management Plan Demand Management Measures Carlsbad Municipal Water District Final June 2016 9-7 Table 9-6: Extent of CWMD’s DMMs, as Reported to CUWCC BMP 2010 2011 2012 2013 2014 Planned Future (2015-2020) 1.1 Operation Practices - Ordinance 44; Ordinance 45 Ordinance 44; Ordinance 45; 2010 UWMP Ordinance 44 Ordinance 44 Ordinance 44 1.2 Water Loss Control Not Quantified Not Quantified Not Quantified 88 Leaks repaired; 14 AF saved 159 Leaks repaired; 30 AF saved Continue to repair leaks in a timely manner.

The popularity of the Turf Removal Rebate displays a need and desire for residential customers wanting a more permeant option to manage outdoor water use and it is expected that this program will be marketed heavily in the next few years as funding is made available by SDCWA. Although all fixtures for indoor conservation that are now available to California customers are water efficient, CMWD still sees their rebate program as a way to continue to encourage additional conservation through high efficiency devices. In the next few years, CMWD will be undertaking two large projects to help reduce system losses: 1. Advanced Metering Infrastructure (AMI) – AMI is being installed currently on the commercial industrial customers. The AMI program will allow CMWD and customers additional monitoring capabilities showing real time water use. 2. Leak Detection – In the next five years, CMWD will be exploring the best leak detection solutions available for use. CMWD will evaluate the use of noise sensors with fixed listening devices and also roving leak detection equipment and decide which method would be best to implement. As demonstrated in Section 5 Baseline and Targets, CMWD’s 2015 GPCD is well within its 2015 target, and is anticipated to remain within its SBx7-7 target for 2020. These savings have been achieved in part to implementation of the DMMs described in this section, and CMWD is committed to continued demand management through ongoing permanent savings (e.g., from landscape conversions), water waste prohibition and waste prevention ordinances, expansion of recycled water service, and other conservation efforts. June 2016 10-1 Plan Adoption, Submittal, and Implementation This section of the 2015 UWMP will address the steps CMWD has taken to adopt this 2015 UWMP, submit it to DWR, and outlines the steps that will be taken should it prove necessary to amend the 2015 UWMP. 10.1 Plan Review and Notification Process CMWD encouraged community and public involvement in the 2015 UWMP by releasing a draft UWMP for public comment and holding a public hearing.

The third year of a multiple‐dry year scenario may result in deficits that must be met through extraordinary conservation or further expansion of the recycled water system. In years with supply reliability, additional purchases would be made from SDCWA to meet demands. As presented here, “% of Average Supply” indicates percent supply available to meet potable demands due to diversification and/or carryover storage. Agency may use multiple versions of Table 7‐1 if different water sources have different base years and the supplier chooses to report the base years for each water source separately.

YElectronics and aerospace manufacturing, energy generation, research development, pharmaceutical. Biotech and energy growing. Room for efficiency improvementsIncrease in industrial demandAre crops grown in your region climate-sensitive? Would shifts in daily heat patterns, such as how long heat lingers before night-time cooling, be prohibitive for some crops? YPrimary crops include avocados, nurseries and citrus which can be climate sensitive, but agricultural land use is expected to decrease. Rise in smaller agricultural/urban farms/residential gardens, and increased crop diversity. Decrease in larger agricultural users.Increase in agricultural crop water demand per acre; small food production use of permaculture could decrease per acre useDo groundwater supplies in your region lack resiliency after drought events? YThe small groundwater basins in the Region tend to decrease resiliency. Increasing impermeability reduces recharge. Sweetwater, Oceanside, Escondido/Vista. Salt water intrusion as water tables drop.Lack of groundwater storage to buffer droughtAre water use curtailment measures effective in your region? YShortage management activities currently in place were effective in meeting demands during the last major drought which began in 2007. Management measures not previously considered, such as soil conditions, may provide additional opportunities.Perceived limited ability to conserve furtherDoes water use vary by more than 50% seasonally in parts of your region? YWater agencies have peaking factors ranging from 2:1 to 6:1. Some of the higher peaking agencies dependent on imported water will have reduced peaking as agricultural use declines and more development occurs. Limited ability to meet summer demandAre some in-stream flow requirements in your region either currently insufficient to support aquatic life, or occasionally unmet? NMost streams are intermittent; however, some agencies that move water between reservoirs via streams have in-stream requirements to protect species during certain times of the year which impacts when water can be moved.Habitat demand would be impactedWater Supply Does a portion of the water supply in your region come from snowmelt? YImported supplies (SWP, Colorado River) come from snowmelt.Decrease in imported supply Does part of your region rely on water diverted from the Delta, imported from the Colorado River, or imported from other climate-sensitive systems outside your region? YApproximately 80% of the Region's supplies are imported. Decrease in imported supply Climate Change Planning Study May 2013 15Vulnerability Question Answer Justification Vulnerability Issue Would your region have difficulty in storing carryover supply surpluses from year to year? NNo, the County has sufficient storage capacity, and is currently completing an emergency storage carryover project. It should be noted that there is little transfer market available in California, with a focus of storage in northern California.Decrease in reliability Does part of your region rely on coastal aquifers? Has salt intrusion been a problem in the past? YSome brackish groundwater exists near the coast which limits the use of coastal aquifers.Decrease in groundwater supplyHas your region faced a drought in the past during which it failed to meet local water demands? YDrought management plans had to be put into effect. It should be noted that the Region has never failed to meet its customers’ demands once drought measures were put into place. Development of additional supplies may reduce the Region’s vulnerability to this issue.Sensitivity due to higher drought potentialDoes your region have invasive species management issues at your facilities, along conveyance structures, or in habitat areas? YQuagga, Arundo, Tamarisk Invasives can reduce supply availableWater Quality Are increased wildfires a threat in your region?

YSeveral water bodies are 303(d) listed for water quality issues related to eutrophication including the Lake Hodges, Famosa Slough, Guajome Lake, Loma Alta Slough, Mission Bay at the mouths of Rose Creek and Tecolote Creek, lower San Diego River, Sal Elijo Lagoon, Santa Margarita Lagoon, Tijuana River, and the Tijuana River Estuary. Increased eutrophication Are seasonal low flows decreasing for some water bodies in your region? If so, are the reduced low flows limiting the water bodies’ assimilative capacity? YAt times during the year, the only flow in some streams is irrigation overflow, which in turn increase the concentration of constituents.Increased constituent concentrationAre there beneficial uses designated for some water bodies in your region that cannot always be met due to water quality issues? YAt times recreation use in some reservoirs is impacted, and beach closures occur. Wildlife habitat and freshwater habitat issues as well.Decrease in recreational opportunity Climate Change Planning Study May 2013 16Vulnerability Question Answer Justification Vulnerability Issue Does part of your region currently observe water quality shifts during rain events that impact treatment facility operation? YTotal dissolved solids (TDS), turbidity and nutrient levels in reservoirs may increase during storm events, impacting water treatment, particularly after fires. Oils and feces show up in reservoirs as well. Increase in treatment needs and costSea Level Rise Has coastal erosion already been observed in your region?YCoastal erosion occurs at unstable bluffs along the coast, for example: Sunset cliff, bluffs along City of San Diego, Encinitas, military infrastructure at Coronado Island and Camp Pendleton..Decrease in land due to erosionDo tidal gauges along the coastal parts of your region show an increase over the past several decades?

Strategies Strategy Description Reduce Water Demand Urban water use efficiency Technological and behavioral improvements that decrease indoor and outdoor residential, commercial, industrial and institutional water use. Crop idling for water transfers Remove lands from irrigation (with the aim of returning the lands to irrigation at a later time) in order to make water available for transfer. Education Implement outreach program to educate urban and agricultural water users in water demand reduction practices. Gray water use Implement gray water use systems to reduce water supply demand. Rainfed agriculture Transfer crop consumptive use to be supplied directly by rainfall. Improve Operational Efficiency/Transfers Conveyance - Regional/local Improvements to regional and local conveyance facilities that improve conveyance capacity, including locating and widening narrow points that constrict the movement of water to increase the water transmission capacity of the entire system, and improve operational flexibility. System Reoperation Change existing operation and management procedures for existing reservoirs and conveyance facilities to increase water related benefits from these facilities. May improve the efficiency of existing water uses or may increase the emphasis of one use over another. Increase Water Supply Conjunctive Management & Groundwater Storage Coordinate and plan use and management of both surface and groundwater resources to maximize the available and reliability of supplies. Recycled Municipal Water Increase supply of recycled water through additional wastewater treatment, and/or expand conveyance of recycled water to end users. Improve Water Quality Drinking Water Treatment and Distribution Develop and maintain adequate water treatment and distribution facilities, and protect the quality and safety of the raw water supply. Groundwater/Aquifer Remediation Remove contaminants that affect the beneficial use of groundwater. Can include passive or active methods. Pollution Prevention Prevent pollution of local surface waters and groundwater using tools that prevent point and non-point sources of pollution. Examples include water management actions and projects such as the increase of local flows, recharge area protection, etc. Salt and Salinity Management Manage salt and salinity in surface and/or groundwater. Examples of methods include dilution and displacement, desalination, and salt collection and storage. The Region is currently working to meet State Salinity/Nutrient Management Planning Guidelines, and will help to implement this strategy. Urban Runoff Management Prevent pollution of local surface waters by implementing best management practices (BMPs) designed to reduce the pollutant loading and reduce the volumes and velocities of urban runoff discharged to surface waters. Improve Flood Management Flood Risk Management Enhance flood protection through projects and programs that assist in the management of flood flows and to prepare for, respond to, and recover from a flood. Practice Resource Stewardship Climate Change Planning Study May 2013 29 San Diego Integrated Regional Water Management Plan DRAFT Strategy Description Agricultural Lands Stewardship Conserve natural resources and protect the environment by conserving and improving land for food, fiber and biofuels production, watershed functions, soil, air, energy, plant and other conservation purposes. Can also protect open space and the traditional characteristics of rural communities. Economic Incentives (Loans, Grants, Water Pricing) Provide incentives such as financial assistance, water pricing, and water market policies intended to influence water management in order to influence amount of use, time of use, wastewater volume, and source of supply. Ecosystem Restoration Improve the condition of modified natural landscapes and biological communities to provide for their sustainability and for their use and enjoyment by current and future generations. Land Use Planning and Management Integrate land use and water management for the planning of housing and economic development needs of a growing population while providing for the efficient use of water, water quality, energy and other resources. Recharge area protection Protect recharge areas to ensure that areas suitable for recharge continue to be capable of adequate recharge rather than covered by urban infrastructure, and prevent pollutants from entering groundwater. Water-dependent recreation protection Incorporate planning for water-dependent recreation activities in water project, and implement project that protect/create water-dependent recreation opportunities. Watershed/Soils/Forest management Create and implement plans, programs, projects and activities to restore, sustain, and enhance watershed functions, soil functions, and forests. Water-dependent cultural resources and practices preservation Create and implement plans, programs, projects and activities to preserve water-dependent cultural resources and practices Increase urban forest management Encourage the planting of trees in urban areas to improve urban water quality and local supplies. Sea Level Rise Building water facilities in coordination with land use/sea level rise (SLR) planning Integrate water/wastewater resources planning with land use/sea level rise planning. Climate Change Planning Study May 2013 30 San Diego Integrated Regional Water Management Plan DRAFT Table 7: Tier 2 Climate Change Management Strategies Strategy Description Improve Operational Efficiency/Transfers Conduct emissions inventory and target Create inventory of all emission coming from water/wastewater operations, and develop a target for reduction of emissions. Increase use of renewable energy sources Use renewable energy sources for the treatment and conveyance of water and wastewater. Increase Water Supply Surface Storage -Regional/local Add or increase the storage capacity of surface storage reservoirs to increase carryover storage and optimize supplies in drought situations. Improve Flood Management Protective Infrastructure Construct flood management facilities to reduce the impact of climate change enhanced flooding. Sediment Management Implement sediment management practices to reduce the impact of climate change enhanced flash flooding. Sea Level Rise Protect water facilities through the relocation or removal of vulnerable structures Relocate or remove water/wastewater facilities that may be impacted by sea level rise. Protect resources and facilities by constructing seawalls or levees Construct seawalls or levees to protect from sea level rise caused by climate change. Protect/restore/create coastal wetlands Protect, restore or create coastal wetlands to prevent the loss of wetland due to sea level rise. Climate Change Planning Study May 2013 31 San Diego Integrated Regional Water Management Plan DRAFT Table 8: Tier 3 Climate Change Management Strategies Strategy Description Reduce Water Demand Water Meters Installation Installation of water meters in order to bill customers volumetrically. Improve Operational Efficiency/Transfers Treatment and Distribution Efficiency Improve treatment and distribution efficiency or water/wastewater systems in order to reduce energy usage. Water Transfers Transfer or exchange of water or water rights that result in temporary or long- term change in the point of diversion, place of use, or purpose of use. Localized Treatment Implement localized (or decentralized) treatment of water/wastewater to reduce the energy required for conveyance. Shift water use to off-peak hours Implement policies that will shift water use (e.g. irrigation) to off-peak hours to reduce evaporative loss. Optimize Sewer Systems Optimize sewer systems (wastewater or stormwater) to adapt to increased precipitation caused by climate change. Increase Water Supply Desalination (Seawater or Brackish Groundwater)Construct desalination plant to treat seawater or brackish groundwater. Indirect Potable Reuse/ Potable Reuse Implement program that will use recycled water to recharge groundwater, or use advanced treated recycled water to augment drinking water supplies.
