EXHIBIT A SCOPE OF WORK INDIAN RIVER COUNTY ALTERNATIVE WATER SUPPLY EVALUATION SURFACE WATER RESERVOIR FEASIBILITY ANALYSIS (PHASE I) AMENDMENT NO.1 PROJECT BACKGROUND In April 2014, the Indian River County (OWNER) Board of County Commissioners authorized CDM Smith Inc. (CONSULTANT) to perform an evaluation of the feasibility of implementing a surface water reservoir to supplement potable water production to meet long-term needs. CONSULTANT delivered a draft of the analysis within 90 days of the authorization, and subsequently performed two significant revisions to that draft. The level of effort to produce the three drafts exceeded the estimate included in the original project budget. The following summarizes the additional efforts by task. The following Scope of Services addresses amended Phase 1 efforts. SCOPEOFSERVICES — PHASE 1 ONLY Consultant will perform the following task services associated with Phase 1 for the development of a surface water reservoir system: TASK 1.0 REVIEW OF PREVIOUSLY PREPARED ALTERNATIVE WATER SUPPLY MASTER PLAN No change. TASK 2.0 IDENTIFICATION OF AND COORDINATION WITH KEY STAKEHOLDERS Task 2.0 initially included 4 hours of coordination with stakeholders, with the balance of the coordination to be conducted by OWNER staff. CDM Smith provided approximately 16 hours of coordination throughout the draft evaluation process. Amendment No. 1 includes provisions for the additional 12 hours of coordination. This effort included additional meetings with the drainage district superintendents, fielding phone calls from various interested parties and coordination with drainage district consultants to obtain necessary information. TASK 3.0 FEASIBILITY ANALYSIS Task 3.0 included a caveat that OWNER staff would provide population projections for use in determining the demand for the 20 -year planning horizon. CONSULTANT was directed to the Metropolitan Planning Organization (MPO) and developed the demand projections through calculations based on the MPO's traffic planning units count. This effort required an additional 8 hours of labor. The original Task 3.0 budget also assumed that the agricultural community would provide the long-term demand projections to be used in sizing the potable plus agricultural demand reservoir option. No agricultural demand projections were readily available to be provided for use. CONSULTANT developed the agricultural demand based on the SJRWMD District Water Supply Plan projections. This effort required an additional 4 hours of labor. A-1 jj1657_Ltr wth Exhibits.doc
