1 Chapter 8.0 PROPOSED CAPITAL IMPROVEMENT PROGRAM This chapter presents the proposed Capital Improvement Program (CIP) for the District based on the findings of this Master Plan. The Master Plan primarily focuses on near term and future capacity needs for the water distribution and wastewater collection systems. There are a number of cases where it will be in the best interest of the District to conduct feasibility or preliminary engineering evaluations before embarking on a major capital investment. Costs for these planning or feasibility studies are also included in the CIP. Detailed CIP projects developed for the District s water and wastewater systems are prioritized capacity or reliability improvements to the existing system. Phase 1 projects represent projects that are underway or expected to be completed in Phase 2 ( ) projects represent high priority projects that should be planned or constructed over the next five years. Lower priority projects are indentified as Phase 3 through 5 projects that would be phased over the following fifteen years ( ). This Master Plan CIP does not include specific rehabilitation or replacement projects due to age or condition of facilities. Rehabilitation and replacement projects have historically been separately identified and budgeted in Master Plan CIPs, mostly based on Operations Department input. The District traditionally combines these replacement and rehabilitation projects with the current Master Plan s capacity and reliability projects for its comprehensive five year CIP program. 8.1 Development of Unit Costs The unit cost estimates reflect full capitalization inclusive of planning, engineering design, environmental, legal, construction, construction management and contract administration. The values are presented in mid-2010 dollars based on an anticipated ENR Construction Cost Index (ENR-CCI) of 9969 for the Los Angeles/Orange County area. These estimates are based on representative available data at the time of this report; however, since prices of materials and labor fluctuate over time, new estimates should be obtained at or near the time of construction of proposed facilities. Unit costs were developed based in part on input from District staff on recent construction projects in the community, comparison with local bid documents for similar projects and unit costs used by other local agencies. Many of the District projects, especially pipelines, require public involvement, traffic control, utility re-locations, and paving replacement, and accordingly have fairly high unit costs. Since some of the pipeline projects are relatively short in distance, a scaling factor has been included to address the economy of scale of constructing smaller scale projects. 1 1 Unit cost data is provided in Technical Memorandum No. 6, Capital Improvement Program, Appendix A. 8-1 Vallecitos District Master Plan

2 The CIP has been divided into five phases as follows: Phase Phase Phase Phase Phase Pipelines Base unit costs for pipeline material and installation including repaving and system appurtenances that, collectively, constitute principal elements of the water distribution and wastewater collection system facilities, are presented in Table 8-1. A base unit cost has been provided for potable water mains, gravity sewers and sewer force mains. Diameter (inches) Table 8-1 Pipeline Unit Costs Potable $/LF Sewer, Gravity $/LF Sewer, Force Main $/LF NA 340 NA NA NA NA 530 NA NA 975 NA The unit costs provided above reflect an average cost for full capitalization inclusive of planning, engineering design, environmental, legal, construction (including all appurtenances), construction management and contract administration. Special circumstances (e.g., jacking, trenchless installations, tunnels, etc.) are considered separately on a case-by-case basis. A scaling factor was applied to each project to account for project specific issues such as difficult conditions, constrained access, congested areas, etc Pump s Pump station capital costs for upgrades are based on the specific upgrade proposed. There are three new water pump stations proposed in the District systems, and four existing water pump stations requiring upgrades. One sewer lift station may be upgraded or replaced with a gravity 8-2 Vallecitos District Master Plan

3 main sewer, depending on a feasibility study. The cost for pump station or lift station projects typically would include pump station building and landscaping, pumps and motors, miscellaneous piping and valving, instrumentation, controls, engineering design, environmental, legal, construction, construction management and contract administration. Unit costs for new pump station or lift station projects were estimated to be approximately $1000 per gpm. Unit costs for upgraded pump stations that simply required pump replacements and electrical/control upgrades were estimated to be $80 per gpm. This assumes no retrofit of the building itself is required to accommodate the new pumps Reservoirs The cost for reservoirs is based on total capacity and includes planning, engineering design, environmental, legal, construction, limited site work, yard piping, valving, fencing and landscaping, construction management and contract administration. Based on District costs for recent reservoir projects, the unit cost for a new reservoir is assumed to be $1.26 per gallon. 8.2 Recommended CIP Program The CIP projects identify facilities needed to meet existing system needs based on the District s design criteria for the water and wastewater systems. As previously discussed, the CIP projects are presented in five major phases of work based on priority needs Supply Since the 2002 Master Plan, the reliability of the District s water supply has benefitted significantly from the construction and operation of the Twin Oaks Treatment Plant. In Chapter 4 of this 2008 Master Plan, additional opportunities to expand or diversify the District s water supply were presented. Of the six alternatives presented, two projects had a moderate to significant impact on improving the District s water supply reliability: Seawater Desalination and Recycled Purchases from Escondido. The desalinated water project, based on the assumption that the Poseidon Desalination Plant in Carlsbad continues to be a viable project, was estimated at this time to be cost neutral to the District; that is, the unit cost of investing in this opportunity is equal to the District s costs to continue to purchase water from the Authority. The recycled water project, however, was estimated to have a unit cost of $3,400 per AF, a relatively high investment compared to the other opportunities to increase supply reliability. Treated water purchases from neighboring water agencies were anticipated to have a minor effect on water supply reliability and were deemed a lower priority for investment. At this time, it is anticipated that the District will continue to monitor the progress of the Poseidon Desalination project and work with the Authority in determining the best means of delivery of the desalinated water to the District. Additional investment in any of the other proposed water supply alternatives is not anticipated at this time. 8-3 Vallecitos District Master Plan

4 8.2.2 Distribution System Proposed CIP projects recommended for the District s water system are shown on Exhibit 8-1 and listed in Table 8-2. The planning level opinions of cost are provided by phase. Pipeline Projects There are 13 pipeline projects proposed in this CIP, and all but one of these projects were proposed in the 2002 Master Plan. The proposed new pipeline project (P-100) includes approximately 1,300 feet of 10-inch pipeline replacement of the water line in Rock Springs Road. A total of approximately 60,180 feet of pipeline is estimated to be constructed or replaced as part of this CIP. Since 2002, the District has completed three pipeline projects that were part of the 2002 Master Plan, including the following: San Elijo Road to Double Peak Road: 900 feet of 10-inch pipeline Twin Oaks II Inlet/Outlet Piping: 180 feet of 36-inch pipeline North Twin Oaks Inlet/Outlet Piping: 950 feet of 12-inch pipeline Pump Projects Of the 8 proposed pump station projects in this CIP, 6 of them are new projects that were not proposed in the 2002 Master Plan. Combined, these projects increase the District s pumping capacity by 17,950 gpm (taking into account only increases in operational capacity). The 6 new projects include the following: Expansion of the Schoolhouse PS Expansion of the Deer Springs PS Expansion of the North Twin Oaks PS Expansion of the Coggan PS A new High Point Hydropneumatic PS A new Desalinated PS Since 2002, the District has completed the construction of 3 new pump stations that were part of the 2002 Master Plan: the 1,500 gpm Double Peak PS, the 3,000 gpm North Twin Oaks PS, and the 1,500 gpm Wulff PS. Reservoir Projects In this CIP there are 11 reservoir projects proposed; all but one of which were proposed in the 2002 Master Plan. The proposed new project is the proposed expansion of the existing Palos Verdes Reservoir to accommodate an additional 520,000 gallons of storage. 8-4 Vallecitos District Master Plan

9 The total amount of additional reservoir storage proposed in this CIP is It is anticipated that at least 8 of the 11 proposed reservoirs will be new above-ground steel tanks adjacent to or in place of existing tanks on padded sites. The Palos Vista #1 tank is proposed to be retrofitted to expand its capacity from 4 to 4.5. The Coggan #3 tank is proposed to be an above-ground steel tank located on a new undeveloped site and will require significant access and piping improvements to reach the proposed site. The Twin Oaks #3 is assumed to be a pre-stressed concrete tank. Since 2002, the District has completed construction of three reservoirs that were part of the 2002 Master Plan: the 3.85 Double Peak Reservoir, the 40 Twin Oaks #2 Reservoir, and the 3.6 North Twin Oaks #2 Reservoir. Deleted Projects A number of CIP projects proposed in the 2002 Master Plan have been deleted from this 2008 Master Plan as the deficiencies that required the proposed improvement either have been addressed in a different manner in this CIP or have been deferred to a date beyond the planning period associated with this CIP. Those projects include: Double Peak Reservoir #2 and Double Peak PS Expansion North Reservoir #2 and connection pipelines Deer Springs Reservoir #3 and connection pipelines A number of smaller pipeline replacement projects in the southeastern and central part of the District (P-58, P-59, P-61, P-65, P-66 and P-67) Connector lines to the proposed Coggan and Wulff Reservoirs San Marcos Mountain and La Cienega pipeline, pump station, and reservoir CIP projects As shown in Table 8-2, the District s CIP Projects for Phases 1 through 5, which are anticipated to satisfy the District s needs through 2030, total $79.8 million. Developer funded projects are anticipated to total $25.6 million Wastewater System Proposed CIP projects recommended for the District s sewer system are shown on Exhibit 8-2 and listed in Table 8-3. The planning level opinions of cost are provided by phase. Since the 2002 Master Plan, the District has completed the expansion of the MRF and a number of pipeline projects including: Linda Vista Sewer Replacement: 2,900 feet of 15-inch gravity sewer Olive Street Sewer Extension: 2,500 feet of 8-inch gravity sewer East San Marcos Boulevard Sewer: 650 feet of 12 and 15-inch sewer Discovery Street Sewer: 4,160 feet of 12 and 15 inch sewer La Habra Drive: 710 feet of 15-inch sewer 8-9 Vallecitos District Master Plan

10 Pipeline Projects Proposed Capital Improvement Program There are 26 proposed pipeline projects, of which 13 were proposed in the 2002 Master Plan, and 13 are new projects. A total of approximately 67,000 feet of gravity sewer is estimated to be constructed or replaced as part of this CIP. Lift Projects Although the District has considered removing the Montiel LS from service and replacing it with a gravity sewer system, because of the difficulties in construction beneath SR-78 and the need to connect to the City of Escondido s sewer system, this CIP assumes the replacement of this lift station. Included in Table 8-3 as a Phase 3 cost, this lift station is estimated to have a construction cost in the range of $1.2 million. Land Outfall Projects The District s Land Outfall was identified in the capacity analysis as being deficient under varying phased conditions and a parallel land outfall was recommended. The Land Outfall is maintained by the District and conveys a majority of the District s wastewater to the EWPCF along with wastewater from Carlsbad and Buena Sanitation District. The Land Outfall is approximately 8 miles long, and conveys flow by gravity pipelines as well as pressure through siphon sections. Due to the total length of the land outfall and the anticipated timing of needed improvements for each section, the parallel land outfall has been divided into six distinct projects. Costs for this project are based on an October 2010 Land Outfall Analysis provided by the District, which assumed that the parallel outfall would convey the ultimate PDWF alone and would be used in conjunction with the existing land outfall to convey the ultimate PWWF. Costs to upgrade this facility may be shared by Carlsbad and Buena Sanitation District, depending on their need for additional capacity. As shown in Table 8-4, the cost of this facility is estimated to be in the range of $28 million. Deleted Projects A number of CIP projects proposed in the 2002 Master Plan have been deleted from this 2008 Master Plan as the deficiencies that required the proposed improvement either have been addressed in a different manner in this CIP or have been deferred to a date beyond the planning period associated with this CIP. Those projects include: Lift stations and force mains associated with developer driven projects that are not anticipated to develop prior to A number of small pipeline replacement projects in the south and central part of the District (P-4, P-6, P-35, P-65, P-91 and P-94). The District s Wastewater CIP Projects for Phases 1 through 5, which are anticipated to satisfy the District s needs through 2030, total $58.5 million CIP Summary The District s total CIP costs are estimated to be $138.3 million. These costs are summarized and shown by phase in Figure Vallecitos District Master Plan
