EXHIBIT A SCOPE OF WORK INDIAN RIVER COUNTY ALTERNATIVE WATER SUPPLY EVALUATION SURFACE WATER RESERVOIR FEASIBILITY ANALYSIS (PHASE I) Background In September 2007, CDM Smith Inc. (Consultant) completed an Alternative Water Supply Master Plan (AWSMP) for Indian River County Department of Utility Services (County). The AWSMP was intended to identify various potential sources of raw water to supply a future water treatment plant (WTP) and address the long-term demand for potable water within the County. The County currently operates two reverse osmosis WTPs that are supplied by a total of 15 production wells constructed into the Upper Floridan Aquifer (UFA). The UFA is relied upon regionally by utilities in Central Florida for potable water supply and locally to supply agricultural operations with irrigation. Rather than rely on this already stressed supply source for long-term planning, options such as surface water treatment, surficial aquifer wells, seawater desalination, and deep wells targeting the Boulder Zone were evaluated in the AWSMP as potential sources. The primary recommendation of the AWSP was for the County to pursue a surface water source, with the next step to be identification of a specific withdrawal point. The surface water withdrawals are proposed to supplement limited groundwater supplies traditionally used by the County. Managing the conjunctive use of these sources will result in improved water availability and reliability for the County. On January 28, 2014, the Board of County Commissioners directed staff to: 1. Review the conclusions of the 2007 AWSMP, which suggests having a surface water supply for the future; 2. Enter into dialogue with the St. Johns River Water Management District (SJRWMD) to obtain the expertise that they can offer; 3. Design a Tong -term system; 4. Analyze the usage of water in the County; 5. Bring the Board a proposal for a feasibility study to develop a fresh surface water system complete with necessary reservoir system; and 6. Include in the proposal a request for funding from the SJRWMD. The development of a long-term alternative water supply will require numerous steps to be completed in phases over the planning period. Specifically, 3 Phases are anticipated. Phase 1 will include initial planning items such as review of the previously completed AWSMP (CDM, 2007), evaluation of the potential site, initial sizing of the reservoir and corresponding surface water treatment plant, and an evaluation of the land acquisition process. Phase 2 would then include final site selection, detailed surface water modeling and land acquisition activities. Phase 3 would include the detailed design of the reservoir system, transmission piping and treatment process, as well as permitting activities. This Scope A-1 p1429REV5 (2).doc,docx 103
