ATTACHMENT A <br /> SCOPE OF WORK <br /> INDIAN RIVER COUNTY <br /> PHASE II - IDENTIFICATION OF SURFACE WATER SOURCE TO BE UTILIZED AS AN <br /> ALTERNATIVE WATER SUPPLY <br /> Background <br /> In April 2004, Indian River County (County) Board of County Commissioners (BOCC) <br /> authorized CDM to design, permit, bid and provide general services during construction for the <br /> expansion of the North County water treatment plant (WTP) . Concurrently, the County <br /> authorized a second consultant to design, permit, bid and provide general services during <br /> construction for the production wells associated with the WTP expansion. Local groups, <br /> committees and districts raised concerns over the continued use of Upper Floridan Aquifer <br /> (UFA) as a source of raw water and questioned the potential for the new wells to impact <br /> existing neighboring users. <br /> As a result, the County authorized CDM in September 2006 to prepare an alternative water <br /> supply plan (AWSP) in order to identify possible alternatives to using UFA wells/ water in the <br /> future as a long-term supply source. CDM held a public workshop on December 6, 2006 with <br /> the BOCC, County staff, South Florida Water Management District (SFWMD) and St. Johns <br /> River Water Management District (SJRWMD) staff to identify the potential alternative sources <br /> for a long-term water supply. At the conclusion of the first workshop, CDM was directed to <br /> proceed in preparing the AWSP, which was intended to: <br /> ■ Evaluate the potential alternative sources (UFA, surficial aquifer, seawater desalination, <br /> boulder zone or surface water sources); <br /> ■ Develop a comparative budget-level cost analysis for each including the resulting impact on <br /> the current rate structure (on a cost per 1,000 gallon basis); <br /> ■ Determine the feasibility of implementing each option; <br /> ■ Identify the schedule that would be required to implement each option; and <br /> ■ Identify the pros and cons of each option. <br /> Upon completion of the report, CDM held a second workshop with the BOCC and County staff <br /> to present the findings and recommend that the County pursue a surface water source and <br /> construction of a surface water treatment plant as a long-term source of drinking water. <br /> Representatives from SJRWMD contributed to the AWSP and also attended the workshop. <br /> SJRWMD and CDM identified several possible surface water sources that could be utilized in <br /> the future. However, the amount of water that will be available in each storage area has not yet <br /> been determined by SJRWMD. Therefore, no specific surface water source was identified as the <br /> preferred source in the AWSP. <br /> The implementation of the alternative water supply from surface water storage areas will <br /> require a phased approach. The various phases are outlined below. <br /> Phase I - Development of the AWSP <br /> Phase I of the program is nearing completion. CDM conducted a kickoff workshop with BOCC <br /> staff, prepared a draft AWSP and presented the findings of the AWSP to the BOCC at a second <br /> A-1 jb1345 WO_Swpe.tl <br />
