The previous plans were completed approximately 5 years ago and assumed that only imported water would be used to meet the District's water supply requirements. Therefore, another element of this work is an inventory of the potential water resources available to the District. Carollo Engineers with ASL Consulting Engineers, Inc. were retained by the District to update the plans. These updates will be integrated with respect to water, reclaimed water, sewer, and other water resource issues. The scope of work for these updates is contained in Appendix A. The District provides water, reclaimed water, and sewer service within the City of Carlsbad, located in coastal, north San Diego County. The District covers most of the City's boundary, with other special districts providing services at the southeast corner of the City. The City of Carlsbad updated the General Plan in 1994. This included land use and population projections. The projections differ somewhat from those used in the previous City master plan. The master plan updates will make use of the most recent growth projections. This is one of five volumes developed for the overall master planning effort. It includes an overall background of the District and the City with respect to service area characteristics, land use, population, geographical and geological features, and interagency agreements. This volume is the basis for the subsequent master plan documents, especially with respect to existing and potential development. This section describes the political subdivisions within the City of Carlsbad. The major agencies include the City and the District. In reviewing the history of these two agencies, it is important to have a perspective as each one's involvement in the water supply and distribution in the area. Until recent history, the development within the existing City limits was confined to the northwest section of the City. The remaining area was mainly unincorporated agricultural lands. The area of the original City development was served by mutual water companies. Most of the surrounding agricultural area was either dry-farmed or served by wells. The District came into existence as a vehicle to provide imported Colorado River water into the area. The District sold this water to the City as well as agricultural users. As the Carlsbad area was developed, the City expanded its limits by annexations. Finally, the District became part of the City as the sphere's of influence became essentially the same. The history of each is outlined below. St(332Aoo\VOL1 .RPT 1 City Of Carlsbad The City of Carlsbad is located in the north coastal region of San Diego County as shown on Figure 1. Its western boundary is the Pacific Ocean. Contiguous cities include the City of Oceanside to the north, the City of Encinitas to the South, and the Cities of San Marcos and Vista to the east. The City boundaries are shown on Figure 2. The City first developed as a rail stop and resort at the turn of the century. It was incorporated as a general law city in 1952. Major transportation corridors include Interstate 5 and the North County Transit District rail line, both running from north to south along the coastal corridor. Palomar Airport Road bisects the City from west to east. This major arterial is used as an alternative to State Route 78 on the north end of the City. Another major arterial is El Camino Real that connects several coastal Cities from north to south. Other major water bodies include Batiquitos, Buena Vista, and Agua Hedionda Lagoons also shown on Figure 2. These lagoons are used for wildlife, recreation, and shell fish aquaculture in Agua Hedionda. The City covers almost 25,000 acres and has a 1995 estimated population of approximately 69,000 (1). Water Supply History The first City water supply came from the San Luis Rey River, north of the City of Oceanside. Wells were first drilled in 1886 by the Carlsbad Land and Water Company. A line was constructed south to Carlsbad to provide the groundwater. The San Luis Rey River continued to be the only supply for the City for many years. The ownership of the facilities and the water rights passed hands several times. The City's water rights in the Sari Luis Rey River date back to 1913 when the South Coast Land Company and the City of Oceanside entered into an agreement for pumping and diversion of 200 miner inches to non-riparian lands. Also in 1913, the Oceanside Mutual Water Company was formed to deliver the water to its stockholders at cost. It was responsible for construction of the distribution and storage facilities. In 1915, the South Coast Land Company sold the San Luis Rey River water rights to the mutual water company. The Oceanside Mutual Water Company became the Carlsbad Mutual Water Company. In 1934, the South Coast Land Company recorded a quit claim deed to the Mutual Water Company further conveying the original San Luis Rey Water rights. By the mid-l930's, the existing wells could not keep up with the seasonal demands. The summer demands exceeded the well output. The groundwater levels in the San Luis Rey River were dropping and groundwater quality was degrading. - S:W3PmVOLl .RPT 2 WATER, SEWER, RECLAIMED WATER MASTER PLANS AND WATER RESOURCES DEVELOPMENT PLAN AREA MAP FIGURE 1 encineers CARLSBAD MUNICIPAL WATER DISTRICT, L In 1935, the Mutual Water Company filed for a 5 cubic feet per second water right from the San Luis Rey River using the existing wells. The water was to be stored in Lake Calavera. Rights for the surface runoff into Lake Calavera were also filed. This led to the construction of Lake Calavera and a water treatment plant. These facilities provided for the required seasonal storage. The wells were used in the winter to fill the reservoir for subsequent summer use. In the mid-l95Os, the Terramar Water Company was incorporated to provide water to a development south of Agua Hedionda Lagoon. The source of water for Terramar were wells in the vicinity of the Rancho Carlsbad golf course. In 1958, the City acquired the Terramar Water Company and the Carlsbad Mutual Water Company. This consolidated the water facilities, with the exception of the District facilities, into the City government. Wastewater Collection and Treatment The collected wastewater is treated and disposed of at the Encina Water Pollution Control Facility. This treatment plant is owned and operated through joint powers agreements by 6 member agencies, which the City of Carlsbad is a member. There are 6 major trunk sewers and 14 lift stations. Two additional lift stations are planned to be operational within the next 2 years. For sewer service, the Vallecitos Water District is responsible for the same area within the City that they provide water service to. The Leucadia County Water District provides sewer service for the entire area within the City served by the Olivenhain Municipal Water District plus additional area as shown on Figure 3. Carlsbad Municipal Water District The Carlsbad Municipal Water District has the responsibility for water supply and distribution for the majority of the City of Carlsbad. The District now also provides for wastewater collection and maintains local sewers, trunk sewers, and lift stations. The sewer collection system was originally a city infrastructure. Beginning in 1993, the District also began distribution of reclaimed (recycled) water. The water service area is shown on Figure 4. The District provides water service for the entire City except for the southeast corner. The Vallecitos Water District covers a small area at the east end of Alga Road. The Olivenhain Municipal Water District is responsible for water service in the southeast corner of the City. - District History The District history began with the formation of the Carlsbad Public Utility District in 1950. This District was formed as a vehicle to import water through the San Diego County Water Authority. Growth was beginning to outstrip the local supplies, which continued to worsen in quality. The boundaries of the Public Utility District were not contiguous with other water agencies in existence or planned for importation of water. The Metropolitan Water District had a policy .L SU33UMKVOLI.RPT 5 L 1 August 13,1913 concerning how areas came into membership as manageable blocks. This led to the formation of the Carlsbad Municipal Water District with the boundaries that exist today. The Carlsbad Municipal Water District was formed and the first meeting held on March 22, 1954. The District was formed as a vehicle to import Colorado River Water into the area. The imported water was being supplied by the San Diego County Water Authority through the Metropolitan Water District of Southern California. The additional supply was needed to support the growth occurring in Carlsbad. Water distribution was still being provided by the Carlsbad Mutual Water Company. On August 8, 1958, the City of Carlsbad completed the purchase of the Carlsbad Mutual Water Company. From 1970 through 1989, the District and City passed several resolutions and numerous supplemental resolutions delineating responsibilities between the City and District. Responsibilities for the water system were generally transferred to the District. The District operated as a separate legal entity until January 1990. At that time, the District became part of the City, with the Mayor and City council acting as the District's board. An advisory Water Commission was left in-place, and provides technical recommendations to the Board. The District also assumed responsibility for sewer and wastewater facilities. The District continues to operate as a water district under the Municipal Water District Act of 191 1. There is a General Manager and District Engineer position. The District is responsible for all water and sewer including planning, engineering, construction, operation and maintenance, billing, and - financing. Currently, all water is imported from the San Diego County Water Authority. The District's system is September 23,1913 a gravity system, with all water flowing from the east to the west. Major facilities include the 200 million gallon Maerkle Reservoir, 11 enclosed reservoirs, 3 booster stations, 54 pressure reducing stations, a hydroelectric generation facility, and 6 inactive wells. A chronology of key District water supply events and history is given on Table 1. The Oceanside Mutual Water Company is formed. It's purpose was to deliver water to it's stockholders at cost. This includes the capability to construct and maintain water distribution and storage facilities. Table I Key aates CaIlSbad ~untcdpai water Wstrtct Envhonmental setting March 14, 1915 The Carlsbad Land and Water Company was organized to drill wells to I 1886 I meet Carlsbad's needs. The South Coast Land Company sells it's interest in the San Luis Rey right to the Oceanside Mutual Water Company. ~ ~ ~ The South Coast Land Company and the City of Oceanside enter an agreement providing for pumping and diversion of 200 miner's inches of water from the San Luis Rey River to non riparian lands. The right includes surface and subterranean water. It also covers the right to construct facilities to pump and convey the water. S:'A33uMhVOL1 .RPT 8 Table 1 Key Dates Carlsbad Municipal Water RIstrlct Environmental Setting January 1,1990 The Oceanside Mutual Water Company changes it's name to the Carlsbad Mutual Water ComDanv. The City incorporates the District as a subsidiary district. The City Council becomes the governing board. October 19,1934 The South Coast Land Company further records a quit claim deed to the Carlsbad Mutual Water Company. The deed further describes the rights to the San Luis Rey River. January 3,1935 The Carlsbad Mutual Water Company files Application no. 8205 with the Division of Water Resources for 5 cubic feet per second from the San Luis Rey River. Water is to be stored in Lake Calavera. Existing San Luis Rey wells are to be used. (Assumed) A Permit No. 5228 was issued for 750 acre-feet per year. September 19,1950 The first meeting of the new Carlsbad Public Utility District was held. The boundaries were basically identical to those of the Carlsbad Mutual Water Company. The purpose of the District was to provide for importation of water through the San Diego County Water Authority. The District was in no way to affect the status or operation of the Mutual Water Company, though there were discussions concerning the acauisition of the ComDanv bv the District. March 22, 1954 December 26,1956 December 26.1956 1958 The Carlsbad Municipal Water District is formed and the first meeting is held. The District was formed as a vehicle to provide imported Metropolitan Water District water into the community and replaces the Public Utility District. The Carlsbad Municipal Water District and the Carlsbad Mutual Water Company enter into an agreement for purchase of water received by the District from the San Diego County Water Authority. The Carlsbad Municipal Water District enters into an Agreement with the Terramar Water Company, a California corporation. This agreement covered the purchase of water from the District to be transported through the facilities of the Mutual Water Company. The Terramar Water Company assets include pipelines and a reservoir in the area south of Agua Hedionda. The City acquires the pipelines and easement assets of the Terramar Water ComDanv. August 1,1958 The City of Carlsbad completed the purchase of the Carlsbad Mutual Water Company for $500,000 in cash. The Agreement was initially entered into on August 30, 1957. The City assumed all debt and obligations and agreed to maintain a differential water rate between agricultural and domestic users. The City further agreed to maintain service to certain areas outside of the Citv limit. 9 7 Other Agencies The District maintains agreements with other agencies for the mutual benefit of each. The other agencies and the agreements are discussed below. Vallecitos Water District The Vallecitos Water District serves the small area within the City of Carlsbad as shown in Figure 3. The Vallecitos Water District's service area is generally the City of San Marcos in addition to portions of Escondido, the City of Vista sphere of influence, and unincorporated portions of San Diego County (2). The service area is approximately 28,700 acres. The District is responsible for water, wastewater, and reclaimed water service. Water is imported from the San Diego County Water Authority. The District owns and operates the 2 million gallon per day (mgd) Meadowlark Water Reclamation Plant. The effluent is used for irrigation within the City of Carlsbad. The remaining wastewater flows through the City of Carlsbad to the Encina Water Pollution Control Facility. Vallecitos is a member agency of the Encina Wastewater Authority. Existing Agreements The Carlsbad Municipal Water District and Vallecitos Water District have several agreements concerning water reclamation. These are discussed below. The significant agreement concerns the District's first right of refusal for up to 2 mgd of reclaimed water from the Meadowlark Water Reclamation Plant. Vallecitos Interceptor In the early 1980's. the flows in the Buena Interceptor were reaching capacity. There was a further need for capacity from the San Marcos area. _- On January 8,1985, a joint agreement was made between the San Marcos County Water District (now the Vallecitos Water District), the City of Carlsbad, and the City of Vista concerning the ownership and operation of the San Marcos County Water District Land Outfall Interceptor. The reach included in the agreement is from El Camino Real west to the Encina Water Pollution Control Facility. This reach is now referred to as the Vallecitos Interceptor. Under the agreement, Vallecitos remains the owner with agency capacity rights as follows: &qlgy Flow CaDac i& City of Carlsbad 5.0 City of Vista 3.75 Vallecitos Water District 12.1 Percent 23.98 17.99 58.03 Fall Safe Line The Fail Safe Line was constructed in the early 1980's to convey treated effluent from the Meadowlark Water Reclamation Plant to the Encina Water Pollution Control Facility. The line was constructed by the developer (Daon Corporation) of the Meadowlark sewer service area. It runs from east to west generally parallel to Palomar Airport Road. S;U133UM)\VOL1 .RFI 10 -~ The Daon also completed the Shadowridge project within the Buena Sanitation District. Another portion of the Fail Safe Line connected the Shadowridge Water Reclamation Plant to the main east-west pipe. The location of the Fail Safe Line is given on Figure 3.1 in Volume IV of this report. Joint agreements were entered into in 1980 and 1981 between the San Marcos County Water District (currently the Vallecitos Water District) and the Buena Sanitation District and the San Marcos Water District and the City of Carlsbad. The agreements dealt with the ownership of the main east-west line. There were three reaches of the line: 1) San Marcos, 2) Buena, and 3) Carlsbad. The San Marcos portion only conveys Meadowlark effluent. The Buena reach conveys a combination of Meadowlark and Shadowridge flows. The third reach was up sized to convey future flows from a potential Carlsbad water reclamation plant to developments then referred to as Carlsbad Pacific Business Center, Lake Calavera Hills Associates, and other developers. The developers paid for the up sizing of the Carlsbad Reach by separate agreement with San Marcos County Water District. The ownership by reach is given below: Vallecitos Carlsbad San Marcos Ranch 100% -0% -0-% Buena Reach 50% 50% -0-% Carlsbad Ranch 16.3% 16.3% 67.4% - The capacities are based on the peak flow rate and the hydraulic capacity of each of the reaches. The developers paid for the Carlsbad reach with respect to the above percentage in behalf of the City. The City is obligated to pay for operation, maintenance, and replacement of the line in the same percentage. Under the agreement, each of the three agencies maintained all rights to the wastewater or reclaimed water in the pipeline until discharged into the Pacific Ocean. Reclalrned Water The Vallecitos Water District and the Carlsbad Municipal Water District entered an agreement in June 1991 concerning the purchase of reclaimed water from the Meadowlark Water Reclamation Plant. The agreement allows the Carlsbad Municipal Water District to purchase up to 2 mgd of reclaimed water matching the plant's capacity. The water quality provided by Meadowlark is to meet Title 22 requirements for unrestricted use as well as having a total dissolved solids (TDS) content of 1,000 milligrams per liter or less. The content could reach 1,200 milligrams per liter in times of drought. The District currently pays Vallecitos $262 per acre foot of water as metered at the District's reclaimed water pump station. The reclaimed water can only be used within the City of Carlsbad. The agreement is in effect for a period of 20 years from date of execution. It will then remain in force on a year by year basis unless terminated by one of the parties. Buena Sanitation District The Buena Sanitation District provides wastewater collection and treatment within the portion of the City of Vista contiguous with Carlsbad. The District is currently administered by the City of Vista. It - S:\4337AW\VOLl .RPT 11 owns the 1 .I6 million gallon per day Shadowridge Water Reclamation Plant. The treated effluent is used to irrigate the Shadowridge Golf Course. There is no excess effluent available during the peak summer irrigation season. Excess effluent is disposed of through the Fail Safe Line as described above. Wastewater not treated at Shadowridge flows through Buena's Encina Outfall to the Encina Water Pollution Control Facility. The Buena Sanitation District is a member agency of Encina. Existing Agreements The Buena Sanitation District has agreements with the City and District concerning outfall capacity and reclaimed water. Encina Outfall The City and the Buena Sanitation District have had several agreements concerning leasing of capacity in Buena's Encina Outfall (Buena Interceptor). The only agreement still in effect was entered into December 15, 1987. This agreement allows the City to discharge a peak flow rate of 0.8 million gallons per day into the outfall. The City is to pay the District $7,500 per year for the use of the capacity. The City can continue to use the capacity until the peak flows in the pipe result in the depth reaching 75 percent of the pipe diameter. Master Agreement for Use of Reclaimed Water The Carlsbad Municipal Water District, the Buena Sanitation District, and the Daon Corporation entered into a master agreement covering the use of reclaimed water in August 1982. The Daon Corporation was the developer of Shadowridge. It provided for the Water District to use excess reclaimed water from the Shadowridge Water Reclamation Plant. The master agreement runs in successive 5 year terms unless any party delivers notice of its intention not to extend it. The agreement may be modified after August 1997 without approval of Daon. The actual conditions of use would be set in supplemental agreements. One such agreement was also executed in 1982 that provided short term reclaimed water for construction purposes. The agreement called for 100,000 gallons per day over a three month period. Leucadia County Water District The Leucadia County Water District provides wastewater collection and treatment for southern Carlsbad, the northern portion of the City of Encinitas, and unincorporated areas of San Diego County. The service area covers 9100 acres (3). A portion of the wastewater is treated at the District's Gafner Water Reclamation Plant. This plant has a capacity of 0.75 million gallons per day. The remaining flow is treated at the Encina Water Pollution Control Facility, which Leucadia is a member agency. The Gafner plant produces effluent meeting Title 22 requirements for unrestricted use, and this water is then sold to the Carlsbad Municipal Water District for irrigation at the south La Costa golf course. Reclaimed Water Agreement. Leucadia and the City of Carlsbad entered into an agreement on March 25, 1991 for reclaimed water by Carlsbad. This agreement covers delivery of up to 0.75 million gallons per day from the Gafner plant. The Carlsbad Municipal Water District is to take a - - - S'U332AM\VOLl .RPT 12 .L minimum of 394 acre-feet of water per year. The effluent quality is to meet Title 22 requirements for unrestricted use. The effluent total dissolved solids must meet the 1.000 milligram per liter requirement as contained in the Vallecitos agreement. During drought periods, the concentration could increase to 1,200 milligrams per liter. The Water District would have first right of refusal for additional quantities. The agreement has a term of 20 years. If the Water District is unable to use the reclaimed water, Leucadia may terminate the agreement with 60 day’s notice. The Water District may terminate the agreement if Leucadia is unable to meet the quality standards. City of Vista The City of Vista is located to the northeast of the City of Carlsbad. Vista is one of the six member agencies that make up the Encina Wastewater Authority, and the City’s wastewater is treated and disposed of at the EWPCF. The wastewater is conveyed through the City of Carlsbad, and the two cities have agreements covering the pumping and the main Vista-Carlsbad Trunk Sewer. Existing Agreements On July 13, 1961, the City of Carlsbad and the then Vista Sanitation District entered into an agreement covering the interceptor system and the Encina Water Pollution Control Facility and ocean outfall. The interceptor system included the Buena Vista Pump Station, the Buena Vista Force Main, and the Agua Hedionda Pump Station. This agreement was revised several times as follows: 0 0 0 0 - August 17, 1971 - Vista is to bear all operation and maintenance costs for the reach from Vista to the City of Carlsbad City limits. September 3, 1975 - Capacity rights are revised. September 14, 1983 - Vista Sanitation District is dissolved and the City of Vista becomes a party to the Basic Agreement. December 27, 1983 - The reach from Vista to the City of Carlsbad as well as a small portion within Carlsbad is deleted from the agreement. The City of Vista assumes sole responsibility. May 22,1987 - The City of Carlsbad submitted a letter for understanding to Vista concerning the upgrading of the VistdCarlsbad Trunk. December 17, 1994 - The Encina Wastewater Authority Revised Basic Agreement with the six Encina member agencies is adopted. Encina will operate the pumps stations at the expense of Vista and Carlsbad. 0 0 The cities are currently negotiating a new agreement covering the operation of the VistdCarlsbad Trunk that includes the two pump stations. It will cover upgrading and operation and maintenance of the system. The City of Carlsbad will assume the responsibility of operation and maintenance including emergency response. The Encina Wastewater Authority will continue the day to day operation of the pump stations by contract. SY332AMhvOL4 .RPT 13 - Ponto Trunk Sewer Agreement In 1972, the City of Carlsbad, Leucadia County Water District, the Encinitas Sanitary District, and the Occidental Petroleum Land and Development Corporation entered into an agreement covering the construction of the Ponto Trunk Sewer. The Ponto Trunk Sewer is now referred to as the North Batiquitos Interceptor. This sewer ends at the Encina Water Pollution Control Facility (EWPCF) and runs south generally parallel to the Pacific Ocean. The sewer was constructed by Occidental for flows generated within the City. The size was to be 27 inches. Encinitas and Leucadia paid to upsize a portion of the trunk to 39 inches to carry flows from these agencies. The up-sizing covered the first 2,415 feet of the 7,400 foot line, starting at the EWPCF. The 39 inch portion, consisting of the 2,415 foot portion from the EWPCF, is owned and maintained by the agencies with respect to the following percentages: City of Carlsbad 40.0% Enciniitas 19.7% Leucadia County Water District 40.3% The 27 inch portion south of the 39 inch portion is owned 100 percent by Carlsbad. - Enclna Wastewater Authority The Encina Wastewater Authority (EWA) provides regional wastewater treatment and disposal for the northern, coastal region of San Diego County. There are six member agencies: the City of Carlsbad, the City of Vista, the City of Encinitas, the Leucadia County Water District, the Vallecitos Water District, and the Buena Sanitation District. The facilities are owned and operated through two joint powers agreements. The treatment is provided at the EWPCF. The plant is located in the City of Carlsbad on Avenida Encinas, south of Palomar Airport Road. Full secondary treatment as well as sludge stabilization and dewatering is provided. The treated effluent is discharged through a deep ocean outfall to the Pacific Ocean. The present capacity of the EWPCF is 36 million gallons per day. The outfall system can handle a peak discharge rate of 105 million gallons per day. The City of Carlsbad owns 9.24 million gallons per day in treatment capacity and 25.5 million gallons per day discharge capacity. This ownership is expected to be sufficient for the City through approximately the year 2010. Resource Agencies Future projects may be subject to review and approval or comment by a multitude of agencies. Instead of attempting to describe in sufficient detail the purpose, authority and responsibilities of each agency in this Plan, the Water District should review at the earliest opportunity its planned future projects with the City's Planning Department. At that point in time the exact agencies to be - 14 - involved in a given project can be determined and appropriate measures can be taken to ensure their participation. For reference, the Master Environmental Impact Report (MEIR) prepared for the City's General Plan identified the following agencies: City of Carlsbad (Lead Agency) United States Fish and Wildlife Service United States Army Corps of Engineers United States Coast Guard National Marine Fisheries Service California Department of Fish and Game California Coastal Commission Caltrans California Department of Housing and Community Development California State Lands Commission California Parks and Recreation Department University of California California Water Resources Control Board, Division of Water Quality California Regional Water Quality Control Board, San Diego Region County of San Diego San Diego County Air Pollution Control District San Diego County Water Authority San Diego County Department of Public Health San Diego Association of Governments North County Transit District Carlsbad Chamber of Commerce Leucadia County Water District Vallecitos Water District Olivenhain Municipal Water District Carlsbad Unified School District San Marcos Unified School District Encinitas Union Elementary School District San Dieguito Union High School District Of the above list, following is a discussion of the agencies that have the most direct impact on the District. Coastal Commission The General Plan describes in greater detail the interaction of the Coastal Commission and Coastal Zone Programs in relation to future development. As a result of the significance of the Coastal Commission, this information is provided below. In 1972, California voters approved Proposition 20 which led to the enactment of the State law (California Coastal Act of 1976) which regulates any development within California's Coastal Zone. The Coastal Act requires that individual jurisdictions adopt Local Coastal Programs (LCPS) to implement the State law at a local level. Carlsbads Local Coastal Program is consistent with the General Plan, but it is a separate document containing separate land use policies and implementation measures which must also be complied with in addition to the General Plan. - Sz133ZAW\vOLl .RPT 15 - Approximately one-third of the City is located within the Coastal Zone. The City's coastal zone has been divided into six segments and each segment is regulated by separate LCPS. The boundaries of the City's Coastal Zone which were established by the State are depicted on the Land Use Map. Almost every conceivable type of development proposal within the Coastal Zone, from removal of natural vegetation to the construction of huge master planned communities, requires the approval of a Coastal Development Permit (CDP) in addition to any other permits or entitlements. The land use policies, programs and regulations of the relevant LCP shall be referred to in addition to the General Plan, the Municipal Code and other pertinent regulations for guiding land use and development within the Coastal Zone. The City has adopted LCP segments for all of its Coastal Zone, and only has authority to issue Coastal Development Permits except for the area of Agua Hedionda Lagoon. Carlsbad is actively pursuing the lengthy task of effectively implementing the five LCP segments in order to transfer permit authority to the City. In those circumstances where an issue is not addressed by the Local Coastal Program Land Use Plan, but is addressed by the City of Carlsbad General Plan, no coastal development permit, or exemption, may be granted unless the project considered is found by the appropriate authority to be consistent with the City of Carlsbad General Plan. In those circumstances where an issue is addressed by both the Local Coastal Program Land Use Plan and the City of Carlsbad General Plan, the terms of the Local Coastal Program Land Use Plan shall prevail. Again, due to the number of potential agencies with authority to review, comment and, in some cases, approve future projects, the Water District should work with the Planning Department on all future projects to ensure the appropriate agencies are involved and to ensure compliance with the California Environmental Quality Act (CEQA). - Regional Water Quality Control Board The Regional Water Quality Control (RWQCB) has jurisdiction over several aspects of the District's operations. These would include: 1) Issuance of Waste Discharge Permits for discharge of groundwater from construction dewatering operations. Approval of reclaimed water applications. Stream bed alteration review under Section 401 of the Clean Water Act. 2) 3) San Diego County Department of Health Interaction with the County Health Department will be necessary for District facilities which involve discharge of reclaimed water. The San Diego County Department of Health Services will review and provide input regarding the RWQCB Reports of Waste Discharge. S~33ZAO7iVOLl .RPT 16 - San Diego Air Pollution Control District (APCD) The District must interface with APCD when facilities have potential to impact the air quality or public health considerations in San Diego County. APCDs main thrust is to ensure both air quality and public health concerns (including toxicology and odor considerations). Treatment facilities which handle flows greater than 1 mgd must apply and secure permits to operate. Currently, APCD is reviewing operating permit applications for the overall wastewater treatment facilities and the biosolids processing facility for the Encina plant. The gas flares for Encina are already regulated by permits issued by APCD. The District could come under jurisdiction if the new reclamation treatment plant was constructed. The District also needs to review the permitting requirements for stationary, standby power generators and odor control scrubbers. California State Health Department The Department of Health Services (WHS) for the State of California enforces the Safe Drinking Water Act. Agencies such as CMWD are required to continually monitor the quality of the water which they purvey to their district customers. Required testing regimens include monthly testing and reporting. Also required are annual inspectionsheports of the District's total system by DOHS. However, due to limited DOHS personnel, these 'annual" inspections occur approximately every two to three (2-3) years instead of every year. Other facilities which may require special permitting by DOHS include any non-standard installation. As an example, any pipeline installation which will not meet the separation and/or depth-of-bury requirements will require special consideration by DOHS permitting (i.e. crossovers, etc.). California Department of Transportation (CALTRANS) The District will be involved with permitting issues with Caltrans for projects that encroach on rights-of-way which are adjacent to state and interstate roadways. In addition to encroachment permits, the District and Caltrans are currently involved in a cooperative agreement involving the 1-5 corridor and reclaimed sources. This agreement allows Caltrans reduced rates for reclaimed water which is to be used for irrigation along the self-constructed reclaimed pipeline. Also, under this agreement, the District will be allowed future accessibility to this line as one means of expanding their reclaimed system. State Fish and Game Involvement with the State Fish and Game Department would be necessary for projects which involve streambed alteration(s) through the 1601/1603 Streambed Alteration Process. The Fish and Game Department also monitors state listed endangered species through Memorandums of Understanding(s) with the affected agency. - - S?4332AW$VOLl .RPT 17 - Additional coastal considerations (such as visual impairmenUimpacts) are addressed through the Natural Communities Conservation Programs (NCCP), which is a subsidiary to the Fish and Game Department. Army Corps of Engineers The Corps of Engineers is responsible for enforcing Sections 404 and 10 of the Clean Water Act. These sections reference the requirements for projects involving adjacent wetlands and drainage considerations. Geography Carlsbads native land form, like much of the Southern California coastal area, consists of an uplifted coastal plain across which east-west drainages have cut systems of alternating mesas separated by riparian valleys and canyons. At the ocean, the mesas terminate as coastal bluffs and the major drainages have formed lagoons. Two of the lagoons, Buena Vista and Batiquitos, and their associated east-west trending form the northerly and southerly boundaries of the City. The third lagoon, Agua Hedionda, effectively divides the City into north and south sectors. The low areas and mesa slopes offer many constraints to development, arising not only from the frequently difficult soils and steep topography, but also from the presence of wetland and riparian habitats which provide homes to a range of sensitive plant and animal species. The upland areas and mesas, being less constrained, are more suitable to development. These geographic influences have shaped development within the City. The geography of Carlsbad and its influence on past development patterns shape, and to a degree, limit the type of urban form that Carlsbad may have in the future. Due to the Agua Hedionda Lagoon (and its drainage), the airport and its influence area, and the power plant with its transmission rights-of-way, the City is effectively divided into northerly and southerly residential sectors. Further, the geographical center of the City is the airport, flanked easterly and westerly by a major industrial, employment generating corridor. In addition to lending definition to the boundaries of the several communities, the land form of the City also provides Carlsbad with truly magnificent scenic and environmental resources. In particular, the lagoons, riparian valleys and canyons, and sage and chaparral covered hillsides bequeath to the City a wealth of environmental riches. However, with this legacy comes the challenge and responsibility to manage and protect these environmental resources at the same time that they are integrated into the future development pattern of the City. To this end, the Land Use Plan calls for a comprehensive and aggressive environmental resource management and open space preservation program (see the Open Space and Conservation Element). One of the major defining characteristics of the City is an extensive network of interconnected greenways, wildlife corridors, parks, trails, and - - environmental preserves. 18 - Geology Introduction The following section provides general descriptions of the geologic formations, stratigraphy, geologic structures, soils and hydrogeologic features of the Carlsbad region and the Mission Hydrologic Subarea of the San Luis Rey River Valley region. Geology plays an important role in the understanding of groundwater hydrology. Groundwater storage, recharge, well yields and other flow characteristics are intricately tied to the physical properties of the surrounding geologic environment. Grain size distribution, permeability and porosity along with corresponding heterogeneities and structural features help define the movement and accumulation of groundwater. Stratigraphy The Carlsbad and San Luis Rey River Valley areas contain rocks which range in age from the Jurassic Period, approximately 139 to 190 million years ago, to the present. Rock types in these areas, from oldest to youngest, include fractured igneous and metamorphic rock, well indurated marine claystone, nonmarine deposits of boulders, cobbles and sand, and marine deposits of poorly to well cemented sandstone, siltstone, and claystone as shown on Figure 5. The Carlsbad and San Luis Rey River region are underlain by granitic rocks of the Cretaceous Period, approximately 100 to 139 million years old, which are intruded into the overlying metamorphic rocks. The metamorphic rocks consist of metavolcanics and metasediments. These rocks are the oldest geologic units in this region and were formed during the Jurassic Period (Leighton and Associates, 1993). Overlying the metamorphic rocks are sedimentary rocks of the Cretaceous Period (Figure 5). A distinct unconformity exists between the sediments of the Cretaceous Period and the sediments of the younger Tertiary Period. An unconformity is a gap or break in the geologic record represented by an older rock unit that is directly overlain by a younger rock unit that is not next in the stratigraphic time succession. This gap may represent a period of nondeposition or a period of increased erosion that leaves no record of sediments that may have been deposited during that period of time. The Tertiary Period began about 65 million years ago and ended about 1.6 million years ago. In Carlsbad and the Mission Hydrologic Subarea, sediments during this period were deposited beginning about 45 million years ago (Figure 5). Tertiary sedimentary rocks are widespread throughout the Carlsbad area and generally consist of varying amounts of sandstones, siltstones and claystones shown on Figures 6 and 7. They are predominantly the result of near shore marine and non-marine deposits that occurred during transgressional and regressional sequences. A transgressional sequence represents sea advancement into the continental land mass due to any change which causes a rise in sea level or subsidence of the land mass. A regressional sequence represents sea withdrawal from the continental land mass due to any change which causes a drop in sea level or uplift of the land mass. - - SUBBUM)\VOLI .RPT 19 Geoloeic Time Qmtemy.

However, the San Luis Rey River Valley, a major drainage area north of Carlsbad in Oceanside, has much thicker sequences of alluvium capable of storing economically significant quantities of groundwater. This area is of importance to Carlsbad because of Carlsbad Municipal Water District's water rights to this basin. Cretaceous and Jurassic igneous and metamorphic rocks are exposed along the eastern portion of the study area. Tertiary sedimentary rocks are exposed along the north and south central portion of the study area. Quaternary rocks are exposed in the western coastal regions and drainages of the study area (Figures 6 and 7). Structure Geologic faults can influence groundwater migration by either increasing or decreasing the permeability of rocks along the fault zone. Faults may increase the permeability of relatively brittle rocks, such as igneous or metamorphic rocks, by increasing the frequency and connectivity of fractures. Conversely, faults may be a low permeability barrier to groundwater flow in relatively plastic rock if clayey gouge forms within the fault zone because of shear forces associated with the fault. There are no known active or potentially active faults within the City of Carlsbad or the Mission Hydrologic Subarea. The closest known active fault is the Rose Canyon Fault Zone located about two to three miles to the west in the Pacific Ocean. There are a number of inactive faults within the City boundaries shown on Figure 8. No inactive faults have been observed in the Mission Hydrologic Subarea (Figure 7). An active fault, as defined by the State of California, Division of Mines and Geology, has had surface displacement in the past 11,000 years. A potentially active fault is defined as any fault considered to have had displacement in the last 1.6 million years. An inactive fault is defined as any fault which has not been considered to have had displacement in the last 1.6 million years. Deformation is a general term for processes which involve folding, faulting, shearing, compression, or extension of rocks. There is little fault deformation evident in the geologic record in the City of Carlsbad. The terrace regions in this area, as with the rest of San Diego County, are mildly dipping down from east to west. Soils Soils in Carlsbad and the Mission Hydrologic Subarea generally range from low permeability clays and clayey loams to high permeability coarse sandy loams (Figure S), (US. Soils Conservation Service, 1973). In Carlsbad, very permeable soils are located near the coast along the Quaternary Terrace deposits and along the drainage areas to the east of Batiquitos Lagoon. In the San Luis Rey River Valley the very permeable soils are located along the sides of the river valley. 23 N NOT TO SCALE WATER, SEWER, RECLAIMED WATER MASTER PLANS AND WATER RESOURCES DEVELOPMENT PLAN INACTIVE FAULTS IN CARLSBAD FIGURE 8 en~ineers CARLSBAD MUNICIPAL WATER - Hydrogeological Features L Tnbfe 2 Webersheds Cadshad Muniolp@ Water Distrfct Environmental Wng .- Buena Vista Watershed The City of Carlsbad lies within the Carlsbad Hydrologic Unit, as described in the Water Quality Control Plan for the San Diego Basin. There are no major groundwater basins within the Carlsbad City boundaries (City of Carlsbad Planning Dept., 1994), although there are a few minor basins associated with the following watershed regions as shown on Table 2. Drain 19 square miles I WATERSHED I DRAINAGE I Agua Hedionda Creek Watershed Encinas Creek Watershed Drains 29 square miles I Drains 3.9 sauare miles Drains 46 I Batiquitos Lagoon Watershed I (San Marcos and Encinitas Creeks) Note: City of Carlsbad Planning Department, 1994 The San Luis Rey River Basin is described as the San Luis Rey Hydrologic Unit and drains approximately 565 square miles (Regional Water Quality Control Board, 1994). The Mission Hydrologic Subarea comprises the western portion of the San Luis Rey Hydrologic Unit (Figure 10). Alluvial thickness generally exceeds 200 feet in this basin. The Mission Hydrologic Subarea covers approximately 29,800 acres. The Mission groundwater basin is contained within the central portion of the hydrologic subarea, where the alluvial thickness is greatest, and covers about 5,500 acres. As of 1983, there were 20 active wells operating in the basin. This is considerably less than was active prior to the advent of imported water during the mid-1960's. Groundwater elevations reached a low of approximately 20 feet below sea level during the late-1950's and have recovered to elevations of approximately 10 to 60 feet above sea level since 1983. Current depths to groundwater have remained fairly constant since the 1980's and are typically five to ten feet below the ground surface (Izbicki, 1985). The estimated total groundwater capacity of the Mission groundwater basin is 90,000 acre-feet. Pumping well discharge from the basin was estimated to be approximately 6,000 acre-feet per year during the 1950's (NBS/Lowry Engineers and Planners, 1993). After water started being imported in the 1960's discharge due to pumping within the basin had reduced to only 500 acre-feet per year by the 1990's. In 1957, total dissolved solids, (TDS), concentrations were often less than 1000 mglL (NBS/Lowry Engineers and Planners, 1993). In 1983 total dissolved solids (TDS) concentrations ranged from 960 to 3000 mg/L and have remained in excess of 1000 mg/L since the 1980's (NBS/Lowry Engineers and Planners, 1993). Increases in salinity are largely attributable to recharge of irrigation water and, according to NBS/Lowry, to a lesser extent the landward intrusion of seawater induced by groundwater pumping.

Other important economic assets of the City include the Palomar Airport, the auto mall, The retail mall at Highway 78, the Village area, industrial parks, the La Costa Resort and Spa, and, Aviara Resort. A major theme park, Legoland, planned to open in 1999 will also have an impact on the City combined with newly planned resort hotels. The City of Carlsbad has developed an Economic Development Strategic Plan for the purpose of ensuring consistency with the adopted General Plan, the Growth Management Program, the 1994 Comprehensive Annual Fiscal Report, 1995-96 Operating and Capital Budget and the City Council's Five Year Vision Statements and 1995 Goals and Objectives. The Strategic Plan is intended to identify roles, strategies and action plans for stabilizing and strengthening the overall economic environment in Carlsbad. The Plan is not based solely on the premise that the recommended actions will produce increased revenues to the City. The Strategic Plan is reviewed quarterly and priorities may be modified to meet changes in the economy or to take advantage of new opportunities. The Plan identifies six important areas of economic focus which are shown in Table 3. Maximizing the benefits these areas bring to the City is a key to Carlsbad's economic health and future growth.

Other Anchors lndustrlal Corrldor Development of Carlsbad's industrial corridor is heavily influenced by the presence of McClellan-Palomar Airport. The glide path, crash hazard, and noise impact areas around the airport significantly influence the type and intensity of development across the entire central area of the City. This area of influence extends generally in a broad band east and west of the runway, and, to a Sz1(332AohVOL1 .RPT 28 lesser degree, north and south of the airport. For reasons of health and safety, residential development and most institutional land uses (hospitals, schools, etc.) must be restricted from this area of airport influence. Due to these constraints, Carlsbad has designated and zoned most of these lands for industrial and, to a lesser degree, office development. The size of the effected acreage in Carlsbad is substantial, creating one of the largest inventories of aggregated industrial land, and correspondingly, one of the largest potential employment generators in North San Diego County. When fully developed, the industrial corridor will provide jobs for Carlsbad and the entire region. Carlsbads position as a major employment center will have increasingly major implications for the City's identity, its role in the region, and its future development patterns. Currently, planned industrial land uses include those areas used for, proposed as, or adjacent to industrial development, including manufacturing, warehousing, storage, research and development, and utility uses. Tourist Oriented Development Tourist oriented developments include commercial uses that provide for visitor attractions and uses that serve the travel and recreational needs of tourists, residents, and the employees of business and industrial centers. Often such sites are located near major transportation corridors or recreational and resort areas such as spas, hotels, beaches or lagoons. Typically these areas are developed along major roadways and are accessible to interregional traffic. Tourist oriented uses such as motels and hotels are coordinated with compatible accessory uses, to protect the surrounding properties, ensure safe traffic circulation and promote economically viable tourist oriented areas of the City. Regional Commercial Development Regional commercial centers provide general merchandise, automobile sales, apparel, furniture, and home furnishing in full depth and variety. Two or more department stores are usually the major anchors of a regional shopping center, while other stores supplement and complement the variqus deparlment store lines. New forms of regional centers may include such developments as outlet centers with an aggregation of factory outlet stores where there are no specific anchor tenants. These types of centers are regional and typically enjoy strong tourist trade. Regional centers attract customers from outside the City and generate interregional traffic. Consequently, such centers are customarily located on a site that is easily visible as well as accessible from interchange points between highways and freeways. Transportation And Related Land Use Development Providing transportation opportunities is an important part of a community's economic development plan. The safe and efficient movement of people and goods within the City, and providing public access to all existing and future land uses is not only important to residents of the community, but also its business sector. Business visitors, customers and suppliers must be able to move easily through retail and business centers. Businesses also varying transportation modes for distribution of their products (Le., rail, road, airplane) and they must be able to transport their goods and services in a timely and efficient fashion. 29 Three areas considered significant to the economic success of Carlsbad are; redevelopment of McClellan-Palomar Airport, development and enhancement of local mass transit systems and the land uses that support them, and refinement of the existing circulation network in the City. McClellan-Palomar Airport McClellan-Palomar Airport is owned by the County of San Diego and is one of the busiest single runway airports in the nation. The airport features a 4,700 feet by 150 feet wide runway, an Instrument Landing System, and an FAA Air Traffic Control Tower. The airport was expected to handle more than 290,000 operations in 1995, including general aviation aircraft, scheduled commuter airlines, charter operations, and military aircraft. Commuter airlines serve thousands of passengers each year with daily flights to and from Los Angeles international Airport. The County is currently developing a new Master Plan for the airport that will focus on elements such as aviation activity forecasts, airfield configuration, airport access, land use, terminal space and support facility requirements. The Master Plan will also examine how general aviation at McClellan-Palomar Airport has adjusted to changes in the marketplace during the last decade, and how the airport can best serve the needs of businesses, based tenants, pilots and other airport users in the future. For the City of Carlsbad, the airport represents a unique economic resource not available in most communities. As air traffic into San Diego's Lindbergh Field increases, more business and resort travelers may take advantage of easy connections to and from Los Angeles International Airport currently available at McClellan-Palomar Airport. In addition, the Airport is conveniently located at the center of Carlsbad's Industrial Corridor and can accommodate corporate jet arrivals, departures and storage. Transit Systems Through a combination of state and local funding, the North San Diego County Transit Development Board and the San Diego Metropolitan Transit Development Board constructed the Coast Express Rail Line. Carlsbad has iwo designated transit stations, one in the Village and the other in the southwest quadrant of the City, near Poinsettia Lane. The rail line currently runs from San Diego to Oceanside, but will ultimately be extended east to Escondido, serving a population of approximately 400,000. In 1992, five Southern California counties concluded negotiations with Santa Fe Railway for the purchase of over 300 miles of railroad right-of-way. This will form the basis, along with Los Angeles' Red and Green Lines, for a rail network that will link communities to a Los Angeles hub (including Los Angeles International Airport) and connect Los Angeles with San Diego. The presence of a rail system connecting San Diego with Los Angeles, Orange, Riverside, and San Bernardino Counties provides the City with an opportunity to evaluate unique, but complimentary land uses adjacent to, and near, both of Carlsbad's transit stations. Mass transit is an important link to the City's future economic development success. Mass transit provides public transportation access for business commuters, day visitors and vacationers. The presence of two rail stations within the City brings a degree of distinction to the community and creates an image of Carlsbad as a destination for both work and play. Coordination of budrail interface and scheduling is handled by North County Transit District. Bus routes have been established to serve the City's rail stations, residential areas and the industrial corridor. sY33umvoLl .RPT 30 - Circulation Network Developing a good circulation system is important to a community's overall development. Access to major freeways and highways is especially important to the manufacturing industy and businesses that rely upon customers and suppliers from throughout the region. A good system will provide for the safe and efficient movement of people and goods within the City and provide for public access to all existing and future land uses. It also identifies how transportation systems will link with surrounding jurisdictions and be coordinated with regional transportation plans. To ensure that circulation facilities are provided concurrently with their need, the City has adopted numerous policies, programs and ordinances, including the Growth Management Plan. A major challenge for the City in the future will be to complete the remaining roadway segments outlined in the City's Circulation Element, in a timely manner. The construction of remaining circulation element roads and public utilities will be brought about through a combination of construction activities undertaken by the development community and the City of Carlsbad. Facility impact fees have been established where a particular facility exceeds the financial capability of any one developer, or the need for the facility cannot be attributed to a single development. These fees are used to generate the revenues necessary to finance construction of the needed facilities. Portions of the circulation network that cannot be linked to future developments must be financed through other local, regional and federal funding sources. Timing for construction of the missing circulation network links is essentially a function of development activity. Village/Redevelopment Area The history of the Village (Downtown) goes back to the 1880's when the rail line linking San Diego and Los Angeles was constructed. In the mid-1880's an underground mineral spring was discovered and Carlsbad soon was being promoted as a resorVspa destination. One hundred years later, in the 198Os, Carlsbad's Downtown was plagued with problems common to many older downtown areas. Buildings were in many cases seriously dilapidated, competition from modern shopping centers had siphoned off much of the area's commercial opportunities and small lot sizes and patterns made it difficult and sometimes impossible to comply with City development standards. In response to these problems, the Carlsbad Housing and Redevelopment Commission established the Village Area as a Redevelopment Project Area under California Redevelopment Law in 1981. Using the powers and privileges granted by that law, the City proceeded to address blighted conditions wlthin the Village. City codes were enforced, some properties were acquired, public parking areas were established, overhead utilities were under grounded, public improvements were constructed and a host of other actions taken, such as the Streetscape Project, with highly visible and successful results. - In 1992, the Carlsbad Redevelopment Agency decided to evaluate the overall progress of the downtown area. As a result, a comprehensive review/planning process was initiated. The primary purpose of the review was to refine the vision for the downtown area, establish more appropriate land use requirements, define supportive development scale and character, and develop a new strategy to further guide and coordinate public and private investment within the Village/Redevelopment Area. The result is a new Redevelopment Master Plan and Design Manual. SY33ZAWJIVOLI .RPT 31 Permitted land uses in the Village may include retail stores, offices, financial institutions, restaurants and tourist serving facilities. Residential uses are encouraged and can be intermixed throughout the area. Community Commercial Development Community commercial centers offer a wide range of general merchandise and specialty goods. Often, a supermarket, large variety store, cinema, or discount department store, functions as an anchor tenant. The emergence of new anchor tenants (Le., high volume specialty or warehouse stores) has resulted in new, special forms of community commercial centers. Sometimes community commercial centers are located next to or across from a regional center because the two types of centers offer different ranges of merchandise. Community commercial centers also may include commercial uses ranging from individual, small lots in the Village and in the industrial areas to larger community shopping/office centers and complexes. Appropriate uses include personal and business retail and service, automobile service, restaurants, and recreational uses. As the City's population and industrial corridor grow, it is reasonable to expect that the need for additional community commercial sites will be generated. It is also reasonable to expect that some existing land uses will be redesignated to commercial uses. As a result, infrastructure requirements may also change based upon these actions. Agriculture While agriculture is an important resource in Carlsbad it is not emphasized as part of the City's Economic Development Strategic Plan. However, the City permanently zoned the "flower fields" in Carlsbad Ranch as a significant tourist and community resource. Agriculture policies contained in the General Plan are intended to support agricultural activities while planning for the possible future transition of land to more urban uses consistent with the General Plan and Local Coastal Program (LCP). The City's LCP protects agricultural lands from the premature conversion by establishing programs which require mitigation for conversion to urban uses. It also has established methods to benefit agriculture in the community by providing financial assistance through cash programs. - .- General Plan The City of Carlsbad, as well as every city and county in the State, is required to prepare and adopt a comprehensive, long-term general plan for the physical development of the city. On September 6, 1994, the City Council adopted its revised General Plan with the passage of Resolution No. 94-246. The General Plan proposes an ideal, end-state in keeping with both the values set out in "Carlsbad - The Vision" and land use policies and proposals. The General Plan is intended to be a living document, onewhich will grow and evolve with the dynamics of the community. The General Plan consists of the following: SY337AW\VOLI .RPT 32 L Low Density (RL) (0-1.5 dwelling units per acre) Growth Control Point 1 .O dwelling units per acre Low Density (RLM) (0-4 dwelling units per acre) Growth Control Point 3.2 dwelling units per acre Medium Density (RM) (4 to 8 dwelling units per acre) Growth Control Point 1 1.5 dwelling units per acre. Medium -Hiah Density (RMH) (8-15 dwelling units per acre) Growth Control Point 11.5 dwelling units per Vision and Introduction Land use Element Circulation Element Housing Element Open Space and Conservation Element Noise Element Public Safety Element Parks and Recreation Element Art Element The General Plan goals, policies and implementation programs will directly effect the future development of the City and the need for water and sewer facilities. In addition, the City's Growth Management Program and Habitat Conservation Program directly impact the need for future facilities and these programs are discussed in greater detail below. Land Use Classifications The land use classifications are described in the 1994 General Plan. The current land use planning is shown by the four City quadrants in Figures 11 through 14. The purpose of the maps is to graphically show the arrangement and the relationship of the various users. The classifications are given on Table 4. 3esidential 2ommercial ~~~ 'lanned Industrial (PI) ~~ Neighborhood Commercial (N) Community Commercial (C) Regional Commercial (R) TraveVRecreation Commercial (TR) Village (V) Office and Related Commercial (0) 5overnrnental Facilities (GI I 'ublic Utilities (U) I 33 Table 4 Land Use Ckrsgltlcattons Carlsbad Municipal WaW WsMct Envlronmeri!al Sewng I Schools Elementary Junior High High School Continuation Private Open Space and Community Parks (OS) Growth Management The transition period between what the City is today and what the ultimate desired character of the City will be is most critical. An area of primary concern is the capability of the City to adequately serve growth as it occurs. To ensure that adequate public facilities and services are guaranteed at all times as growth occurs, the City developed a Growth Management Program which was subsequently ratified by Carlsbad voters in November, 1986. This program establishes citywide, quadrant, and Local Facilities Management Zones performance standards for eleven public facilities. The Local Facililty Management Zones are shown on Figure 15. The eleven public facilities addressed are city administration, library, wastewater treatment, parks, drainage, circulation, fire, open space, schools, sewer collection, and water distributiodstorage. The program requires that the appropriate public facilities must be available in conformance with the adopted performance standards in an area when new development occurs. Unless each of these eleven public facility standards have been complied with, no new development can occur. Compliance is planned for and provided through a three-tiered or phased planning process as described below. Tier 1 - Citywide Facilities and Improvements Plan - adopted in 1986 includes eleven public facility performance standards, defined the boundaries of twenty-five local facility management zones, and detailed existing public facilities and projected the ultimate public facility needs. Tier 2 - Local Facilities Management Plans - are prepared for each of the twenty-five zones and implement the provisions of the Growth Management Program.

These plans phase all development and public facilities needs in accordance with the adopted performance standards, provide a detailed financing mechanism to ensure public facilities can be provided. Tier 3 - Individual Projects - must comply with the provisions of the Local Facilities Management Plans, as well as implement provisions of the Citywide plan. In addition, this third tier of the program includes the review of individual projects to ensure compliance with all performance standards prior to the approval of any development permits . The Citywide Facilities and Improvements Plan made an estimate of the number of dwelling units that could be built as a result of the density ranges in the Land Use Element. For the entire Citv a build out. the estimate was 54.600 dwellino units and an estimated OoDulation of 135.000. The purpose of this estimate was to provide an approximate number of ultimate future dwelling units and population citywide and for each quadrant for facility planning purposes. The City's Capital Improvement Plan, Growth Management Plan, and public facilities plans are all based on this estimate. To ensure that all necessary public facilities will be available concurrent with the need to serve new development, it was necessary to set a limit on the number of future residential dwelling units which can be constructed in the City. The City determined the maximum number of future dwelling units which could be constructed in the four quadrants along El Camino Real and Palomar Airport road. The maximum number of future dwelling units which may be constructed or approved in each quadrant after November 4,1986 is as follows: Northwest Quadrant 5,844: Northeast Quadrant 6.1 66: Southwest Quadrant 10,667: Southeast Quadrant 10.801, When the Growth Management Program was ratified by Carlsbad citizens through an initiative, the voters mandated that the City not approve any General Plan amendment, zone change, tentative subdivision map or other discretionary approval which could result in future residential development above the limit in any quadrant. This mandate will remain in effect unless changed by a majority vote of the Carlsbad electorate. The City's Growth Management Program has adopted performance standards that relate specifically to sewer and water facilities which must be met in order to allow development to occur. These performance standards are shown below: Wastewater Treatment Capacity Sewer plant capacity is adequate for at least a five year period. Sewer Collection System Trunk line capacity to meet the demand as determined by the appropriate sewer district must be provided concurrent with development.

The General Plan and Growth Management Programs have taken these programs into consideration as the projections of future and ultimate growth were determined. As the Water District coordinates future projects with the Planning Department, consideration and interaction with these various habitat programs will need to occur. 1970 The City of Carlsbad has grown significantly over the past 35 years. In this period, the population has increase almost eight fold from 9,253 in 1960 to a population of 63,451 in 1990 (1). The historical and projected population is given in Table 6. The estimated population of 80,000 in 1995 is higher than has actually occurred. The City estimates the current population at 69,000. While growth has been slower than projected, there is currently significant development planned over the next two years. -. 14,944 1980 I Population Year 1960 9,253 35,490 1982 1983 37,583 38,827 I 1981 I 35,725 I -. 1984 39,963 1985 43,685 SU3!3ZMo\VOL1 .RPT 45 Table 6 Population Trends Carisbad Munidpai Water RisMct Envlromental scatting I I 47,810 1986 1988 1989 I 1987 I 53,900 I 58,850 61,948 1990 63,451 I 80,000 1995 2010 - I 2000 I 95,000 I 110,820 Table 7 Senrlce Aree Populati~ Cartsbed MuUniCrpal WaW..DlStriat Environmental Wng -, Ultimate population has been estimated at 124,650.

District Population The population served by the Carlsbad Municipal Water District will vary somewhat from the City population. This is due to the overlapping by other special districts that provide water and sewer service. The District service population by both water and sewer has also been estimated. The historical service population for the last 5 years is presented in Table 7. The ultimate service populations are also given. This is based on the land use as presented in the General Plan (1).

When the coastal plain of northern San Diego County originally started to develop in the 18M)'s, the local resources, predominantly the San Luis Rey River were tapped to provide the water resources necessary for the growing population and agriculture. Carkbad initially developed facilities to use San Luis Rey/Mission Basin in 1913. Groundwater was the next significant contributor to the region's developed water supply. However, State Water Rights decisions of the 1930's ruled that groundwater in the Mission Basin were the equivalent to subsurface flow of the San Luis Rey River thereby curtailing claims on groundwater rights and efforts to significantly expand its use. Carlsbad acquired the Cannon wellfield facilities to expand its groundwater production capability in the 1950's. Neither of these wellfields is in operation today. With the end of World War II in the mid 1940s, population in San Diego County began to burgeon as it did throughout southern California. The United States Navy also had plans to expand its presence in San Diego and was concerned about the reliability of the local water supply. While the San Diego County Water Authority (SDCWA) did have certain rights to the Colorado River, they had yet to make any long term commitments to transport their entitlement to San Diego. Under pressure from the U.S. Navy, SDCWA joined the Metropolitan Water District of Southern California (MWDSC) for the purpose of obtaining supplemental water from the Colorado River. As a condition of joining MWDSC, SDCWA had to forego their independent rights to Colorado River water. In 1951, realizing that they were using the bulk of their local water resources, Carlsbad applied to join the SDCWA. Not only were they reaching the limit of the local resources in terms of quantity, the water quality (high in TDS) was becoming detrimental to agricultural which represented a significant portion of the delivered water supply. Carlsbad's rights to these various sources of supply can best be described through a brief overview of California water rights practices. The basic California water rights 'rules" can be summarized as follows: All water belongs to the state. Rights for the use can be obtained, but not ownership of the water. If you own land contiguous to a stream within the stream's watershed, you have a riparian right to use water from the stream. If you are not riparian, you must have a permit to use surface water. The appropriative permits are issued by the State Water Resources Control Board (SWRCB). If you own land, you have a right to use groundwater underlying that land. S11332AWVOLI .RPT 47 No use can be wasteful or unreasonable (Article 10, Section 2 of the State Constitution). There have been a number of clarifications of or refinements to these "rules' over the years. Some of these are as follows: Riparians have priority over appropriators. Senior appropriators have priority over junior appropriators (first in time, first in right). Riparians and groundwater users share shortages; appropriators do not. Appropriators who do not use water for three years lose the right to that use. Riparians cannot lose their right by non-use unless the stream is adjudicated; then, the court can cause dormant riparians to be junior to all other rights. Riparian land, once "severed", can never be riparian again. Pre-1914 appropriators (year the appropriative law was implemented) have better rights than post-1 914 appropriators. Some watersheds and groundwater basins have been adjudicated by the courts (not in Carlsbad). Adjudicated rights supersede all others. The SWRCB can fine unauthorized diverters and issue cease and desist orders against violators of water rights conditions. The SWRCB can temporarily grant water rights and change those already granted (especially useful during droughts). The federal government, which owns about 50% of the land in California, has riparian rights for water for the primary purposes for that land, but must apply to the SWRCB when it intends to exercise such right so the SWRCB can determine if the right is consistent with efficient, beneficial use of the state's waters, and must apply for appropriative rights for water for secondary purposes. Appropriative rights have certain conditions attached: Amount Type of use Area of Use Season of use Diligence Conditions to protect the public interest First, get a "permit", then, alter use is accomplished, get a "license". The priority is the date of application of application for the permit. The forgoing is just a brief summary of some of the water rights issues that may affect Carlsbad's rights to its various water sources. A more thorough discussion of water rights, including the State Water Project and the Colorado River, is contained in Volume V, Water Resources Development Plan. Wastewater The Carlsbad Municipal Water District provides wastewater collection for the majority of the City. The system includes local collection sewers, trunk sewers, and lift stations. There are 6 major drainage basins and 5 existing trunk sewers. The sixth trunk, the South Agua Hedionda Trunk is a subject of this master planning effort. There are currently 14 lift stations owned and operated by the District and 2 owned and operated jointly between the District and the City of Vista. - SU332AWVOL1 .RPT 48 The wastewater is conveyed to the Encina Water Pollution Control Facility (EWPCF). There it is treated and disposed of into the Pacific Ocean. A small portion is reclaimed for on-site users and irrigation of CALTRANS right-of-way along the plant's eastern property line. The EWPCF is owned and operated by six member agencies through a joint powers agreement as discussed in a previous section. The member agencies include the City of Carlsbad, the Cities of Vista and Encinitas, the Vallecitos Water District, the Buena Sanitation District, and the Leucadia County Water District. The capacity of the EWPCF is 36 million gallons per day. It is expected that the next expansion will not be needed until some time around the year 2010. The treatment plant provides full secondary treatment levels. Reclamation Beginning in 1993, the Carlsbad Municipal Water District began the distribution of reclaimed wastewater. In 1995, a total of 1,036 acre-feet of water was delivered. Major users include the Aviara development, Aviara Golf Course, and the La Costa Resort and Spa. The source of the reclaimed water includes both the Meadowlark Water Reclamation Plant owned by the Vallecitos Water District and the Gafner Water Reclamation Plant owned by the Leucadia County Water District. The water is sold to the District by these two agencies. The agreements are discussed in a previous section. Water and Sewer User Charges The District sets rates and charges for both water and sewer service. This includes monthly user fees and connection fees for new users. The system of charges was reviewed in 1995, and the final Report for Water and Wastewater Rate Study and Financial Plan was issued in January 1996. - .- The study evaluated the current fee structure, including the method for calculating the fees. A series of recommendations were made concerning the rates and methodologies. These are summarized below: 0 Rates should be increased by an average of 7.5 percent in 1995. It was recommended that the conservation rate be extended to all users based on meter size. No further increase was foreseen for Fiscal Year 1996-97. A five percent discount for reclaimed water was recommended. The alternative would be to keep the same parity with the District providing the reclaimed water retrofits. Water rates will need to be increased in future years to cover the higher cost of imported water as charged by the Metropolitan Water District, for capital improvements, and reserve funding. Connection fees were recommended to be based on meter size. The connection fee should include the New Demand Change component charged by the Metropolitan Water District. A monthly charge should be levied for the backflow inspection program. This is only for non-residential users. 0 0 0 0 49 .-.- Wastewater 0 0 The project increase in sewer charges was estimated at 3 percent per year to cover inflation. A system of charges based on water use was recommended for residential users. The initial program would only switch multiple family units to water use with single family based on a flat rate or average winter usage. Collection of fees for studios connected to single family dwellings needed to be addressed. Adopted Rates Based on the January 1996 report, the District adopted new fees on June 4,1996. Important aspects of the fee structure includes the following: 0 0 0 0 0 The Commodity cost for reclaimed water is 5 percent less than potable water. Users will be responsible for retrofit costs. Residential multi-family users will pay sewer fees based on water usage. Single family users will continue to be on a fixed monthly charge. Potable water connection fees were revised from an equivalent dwelling use basis to meter size. Reclaimed connection fees are the same. On January 1, 1997, the potable water fixed charge per dwelling unit will be eliminated for multiple family dwellings. The allocation of the commodity rate was retained. A conservation rate for all customer classifications is in effect as of January 1, 1997. A copy of the rate resolutions is included in Appendix 6. - 50 Appendix A Scope of Work s:u332mvoL1 .RPl EXHIBIT "A" _- WATER, SEWER, RECLAIMED WATER MASTER PLANS AND WATER RESOURCES DEVELOPMENT PLAN SCOPE OF WORK 1.

H CITYATTYrn POTABLE WATER, RECLAIMED WATER AND WASTEWATER SERVICES RECOMMENDEDACTION: (JOINT CIm co~cIL/c~ BOARD OF DIRECTORS METING) Hold a public hearing and adopt Resolution No. 9 37 setting various rates and fees for potable water, reclaimed water and wastewater services provided by the Carlsbad Municipal Water District; and Mopt City Council Resolution No. 9b-14 setting various rates and fees for potable ITEM U(~~NATION: water, reclaime -hl water, and wastewater services. In April of 1995, the Carlsbad Municipal Water District embarked on a rate study that was to look at the following issues and arrive at certain recommendations. Issues IEPT. CMWD Customers with large meters do not pay water delivery charges proportional to the demand they place on the system. Multi-family units are required to pay delivery charges for each multi-family unit in addition to the delivery charge established for each water meter. CITY MGR. ' Currently, water connection fees are based on Equivalent Dwelling Units (EDU's) defined for sewer use. This allows some users to receive water service without paying their full share of connection fees. The financiq of several major capital improvement projects needs to be reviewed. The Metropolitan Water District has revised its rate structure. As a result, CMWD rates need to be adjusted to produce adequate revenues to meet expenses. The impacts of reclaimed water service on potable water need to be examined Residential wastewater service charges for single family and multi-family units need to be reviewed to enhance equity between these user groups. 4 review was done mth input from a Citizens Review Cornrniatee (Commitse). Mer educatag :omrnittee members on the various issues, the intent was to solicit input kom the ccmmdtee D assist staff in identifying available alternatives to address these issues and to anatyze Me npacts of aanges on the DiMa as well as Uw DistritricYs customers. This Committee produced I final report that represented their efforts to grcvide community input to the process af lesigning a new water rate structure. This Committee report was presented to the Water :ommission and Board of Directors in September of 1995. hce the Committee's report was presented and received, the consultant used the report to Koduce the Water and Wastewater Rate Study and Financial Plan. his plan has been reviewed by st& over the last few monUis and a final draft has been iroduced. The following recommendations are presented in the Plan: ‘ Page 2 of Agenda Bill No. 22 ‘1 -. 1. Water Rates - Delivery Charge: Revise the monthly fixed charge (‘Delivery Charge’) to more fairly reflect the demand each meter places on the system. This revision will result in an increase in the monthly fixed charge for each meter size and type of water user. Analvsis - The existing Delivery Charge is a fixed charge which includes a capacity charge and a customer charge that is fixed for each customer. This charge should be revised in accordance with Exhibit 3 (‘Monthly Delivery Charges’) of the attached Resolution. This table shows the existing Delivery Charge in accordance with meter size. This existing charge has been adjusted to show the proposed new Delivery Charge as listed in the right- hand column. The proposed new charge more accurately reflects the demand each meter places on the water system. The adjusted Delivery Charge includes a portion of the new Ready-To-Serve (RTS) charge previously imposed by the Metropolitan Water District. The Delivery Charge should also be revised to create equity for Multi-family residential customers. This would be accomplished by charging Only the Delivery Charge for the meter, based on size, and not for each additional residential unit as now exists. 2. Water Rates - Commodity Charge: Retain the existing rate structure and rates; Le., no rate increase is recommended. L Analvsis - The Commodity Charge (the charge for each unit of water consumed) reflects those costs that vary with the quantity of water used. These costs include the cost of purchasing and treating water. In addition, a part of the operations and maintenance costs, and capital costs of improvements are allocated to the Commodity Charge. The existing rate structure, including a conservation rate, should be retained. The Committee recommended that the conservation rate be extended to all classes of customers. This would be accomplished by establishing a conservation usage limit for each meter size as shown on Exhibit 5 (‘Commodity Charges’) of the attached Resolution. This new rate includes the remaining portion of the Ready-To-Serve (RTS) charge, the balance of which is placed on the aforementioned delivery charge. A comparison of the allocation of water costs is presented on Exhibit 4 (‘Allocation of Water Costs’) of the attached Resolution. The Meqlitan Water District is also imposing an increase of $5.00 per acre foot on imported water costs. Both of these charges are scheduled to take effect January, 1997. 3. Water Rates - Connection Fees: Revise the potable water Connection Fees from an Equivalent Dwelling Unit (EDU) basis to a meter size basis to more fairly reflect the demand each new meter places on the water system. Analvsis - The method of assessing Connection Fees should be revised and based on meter size rather than the existing EDU calculation. This “fair share’ approach will result in some increases and some decreases in actual connection costs depending on the size of meter connected to the system. The recommended connection fees for different meter sizes are as shown on the attached Exhibit 2 (‘Potable and Reclaimed Water Connection ‘Fees“). Connection Fees should be revised annually to recover the increased New Demand Charge (NDC) previously charged by the Metropolitan Water District. Connection Fees d . Page 3 of Agenda Bill No. 76. c! _1* 1 should not be charged for retrofits if there is no increase in capacity. - 4. Backflow Connection Program: The monthly fee for administering the badmow connectim program should be increased from $2.50 to $3.00 per backflow account. ,-. i .L halvsis -The Badmow Connection Charge is required for non-residential users only and covers administrative costs related to maintaining records and administering the Badmow Program. 5. The Water Enterprise Fund: The Water Enterprise Fund Operating and Capital Replacement Reserves have adequate balances and do not need additional cash. Analvsis - For FY 199596, the Operating Reserve is at 49 percent. Normal utility practice is to provide a balance in the Operating Reserve of between 10 to 50 percent of annual operating expenses. This reserve is used for working capital and emergencies. Interest on the funds in this reserve may be used to finance operations. Normal utility practice is to maintain a Capital Replacement Reserve with a balance of between 50 to 100 percent of the average annual capital expense for the next five to ten years. The District has adequate reserves to meet this requirement. This reserve should be maintained at the present level to krnd future capital replacement and upgrade projects. The Capital Expansion Reserve is projected to be depleted by the planned capital expansion projects due to the slow growth and reduced connection fee revenues. The District should consider delaying some of the capital expansion projects if the growth rate does not pick up. 1. Reclaimed Water - commodity Charge: Implement a five percent discounted Commodity Charge rate for reclaimed water use with water users bearing the costs of retrofitting. Analvsis -The Committee recommended a five percent discount for reclaimed water use and let users bear the costs of retrofitting, Retrofits are required to convert. or replace potable water connections with reclaimed water connections to provide reclaimed water service. 2. Reclaimed Water - Connection Fees: Establish new reclaimed water connection fees as shown in Exhibit 2 of the attached Resolution. Analvsis -New reclaimed water connections should be charged a Connection Fee equal to that of potable water connections as shown on Exhibit 2 of the attached Resolution. Reclaimed water users are not required to pay San Diego County Water Authority’s connection fee. .- 3. Debt Financing: Seek low cost loans from the State Revolving Fund. Analvsis -The expansion of reclamation facilities will require debt financing. The District should seek low cost loans from the State Revolving Fund. .. ’ Page 4 of Agenda Bill No. -?A ‘1- Recommendations - Wastewater Services 1. Wastewater Enterprise Fund: Increase wastewater rates based on a projection of three percent per year. Analvsis -The Wastewater Enterprise Fund is in good financial condition. Only small rate increases are needed to maintain pace with inflation. The projeded rate increases are three percent per year. 2. Wastewater Sewices Rates: Revise the rate system for charging wastewater services for residential multi-family units from the existing fuced rate to a water use-based (“flow based‘) system; continue to charge single family homes a fixed charge. Analvsis -The Committee recommended that wastewater rates for residential customers be based on water use, This would be similar to rates for non-residentiat customers. Since the major portion of the wastewater service charges are from residential customers, and water use can vary significantly from year to year, this type of rate structure makes the District vulnerable to fluctuations in revenue. To ensure that revenues are not too high or too low, rates would need to be reviewed on an annual basis. Staff recommendation is to switch multi-family units to a water use-based system, but continue to charge single family homes a uniform charge. Flat or uniform residential rates, as well as rates based on average winter use for single family residences and based on monthly water use for multi- family residences, are presented on Exhibit 1 (“Wastewater Rate’) of the attached Resolution. It is recommended that multi-family wastewater rates be based on a portion (e.g., 90%) of monthly water use. It should be noted that the rate increase for single family units will be significantly higher and other users will actually benefit from a rate reduction. 3. Wastewater Fee - Second Dwelling Units (Granny Flats): Implement a new wastewater fee for second dwelling units (‘granny flats’). Analvsis - An additional wastewater fee should be charged for second dwelling units (‘granny flats’) to ensure that adequate fees are collected for wastewater service. It is expected that these units will be used by single individuals in most cases; therefore, this new charge should be 40 percent of that for a single family residence 4. Wastewater Sem’ces - Enterprise Reserves: The Wastewater Enterprise Reserves have adequate balances and do not need additional cash. Analvsis - The Wastewater Enterprise Reserves are in good condition and should be maintained to meet operating and capital replacement needs in the future. The Capital Expansion Reserve which is used to pay off debt service is being depleted at a fast pace because of reduced revenues from connection fees due to slow growth. -. 5. Wastewater Services - Capital Improvement Projects: The District will need to issue debt of $5 million in 1996-97 and $4 million in 1998-99 to meet the cost of expansion- related wastewater capital improvement projects. .. . Page 5 of Agenda Bill No. 3 2-q FISCAL IMPACT: Water - Retail water rates must be increased to wver the wholesale increases from the Metropolitan Water District through the San Diego County Water Authority or an annual shortfall would exist that amounts to $390,000 for 1996-97. These increases represent the Ready-to- Serve charge to CMWD of $316,072 and the increase of $5.00 per acre foot to the cost of water. The increase of $415 to the Water Connection Fee represents the New Demand Charge that has been instituted by Metropolitan Water District. This connection fee must be increased to offset the New Demand Charge or a shortfall will occur when the District increases its average baseline imported water purchases. L A monthly Backflow Device Inspection Fee of $2.50 is currently charged to cover the costs of administering the badmow connection program and the charge is made only to those customers requiring a backflow device. The recommended fee increase to $3.00 will wver the administration costs of maintaining records of the locations, tests and repairs on each backflow device. Reclaimed Water - A five percent discount for the commodity charge would result in a shortfall of $52,000 based on reclaimed water sales of 1,400 acre feet. This shortfall is proposed to be made up through a subsidy ofthe potable water rate. The effect on the potable water rate would be $0.01 per unit of water and results in the proposed $1.70 per unit rate. Wastewater - There is no fiscal impact to the wastewater enterprise fund as a result of the recommendations in this rate study. The adjustments to the single family residential customer and to the multi-family residential customer offset each other, therefore, total revenue remains unchanged. i-- ._ - EXHIBITS: 1.
