The study not only evaluated an alternative water supply through a surface water reservoir, <br /> it also investigated Aquifer Storage and Recovery (ASR), seawater desalination and an existing well <br /> abandonment program. The Board directed staff to negotiate a cost proposal with CDM Smith, Inc. <br /> (CDM),to embark on Phase 2: Modeling to determine the available volume of water in the Sebastian <br /> River Improvement District's (SRID) canal system. <br /> ANALYSIS: <br /> A draft of the Phase I-Preliminary Evaluation report by CDM was posted January 21, 2015 on the <br /> County website. An electronic copy of the report was also shared with several stakeholders soon <br /> after the BCC meeting. Due to the size,the report is made available on the County website under the <br /> following URL: ! . ,;,_T r Indian River County <br /> Department of Utility Services (IRCDUS) staff and CDM staff met with St. John's River Water <br /> Management District (SJRWMD) on February 25, 2015 to discuss their <br /> comments/concerns/suggestions on the Phase I portion of the report. Staff also attended the Indian <br /> River Soil and Water Conservation meeting held April 14, 2015 to address their comments. At that <br /> meeting they offered comments/suggestions verbally and followed those with a written letter to the <br /> consultant at a later date. The subject draft has incorporated those comments into an Appendix of <br /> the Phase I report. <br /> Phase I of the evaluation involved more consultant time than originally anticipated. Some of the <br /> additional time is related to attending numerous stakeholder meetings, coordination and answering <br /> questions. Those hours are detailed in Attachment 1. The total negotiated cost for the additional <br /> work is a lump sum amount of$ 14,750.00 which results a new total lump sum cost for Work Order <br /> No.11 in the amount of$85,655.00. <br /> Page 1 of 4 <br /> F:\Utilities\UTILITY-Engineering\WATER\Alternative Water Supply\2014 Alternative Water Supply\Admin\Agenda-Alternative Water Supply 109 <br /> Evaluation-6-11-15.docx <br />
