EXHIBIT A <br />INDIAN RIVER COUNTY <br />ALTERNATIVE WATER SUPPLY EVALUATION - SURFACE WATER <br />RESERVOIR FEASIBILITY ANALYSIS PHASE 2 <br />May 14, 2015 <br />This Authorization, when executed, shall be incorporated in and become part of the Continuing Contract <br />Agreement for Professional Services between the Indian River County Department of Utility Services <br />(OWNER), and CDM Smith Inc. (CONSULTANT), dated December 6, 2011, and the Extension and <br />Amendment of Continuing Contract Agreement for Professional Services, dated November 4, 2014, <br />hereafter referred to as the Contract. <br />PROJECT BACKGROUND <br />In April 2014, (OWNER) authorized CONSULTANT to perform Phase 1 of the Surface Water Reservoir <br />Feasibility Study. The final draft of that evaluation was completed in early December 2014, and is <br />currently under review by the OWNER and stakeholders. At the January 20, 2015 Indian River Board of <br />County Commissioners (Board) meeting, the Board directed staff to develop the scope of services for <br />Phase 2, which includes data collection and stormwater modeling to determine the quantity of water <br />available in the surface water network within the Sebastian River Improvement District (SRID). The Study <br />Area is shown in Figure 1. The following is the detailed scope of services for Phase 2. <br />SCOPE OF SERVICES <br />TASK 1- DATA COLLECTION, COMPILATION AND EVALUATION <br />Subtask 1.1— Model Data Compilation and Review <br />To support the modeling efforts, the CONSULTANT will compile existing data on the canals (L, C, D and <br />Bypass), the downstream location (just south of County Road 512 Bridge) where all 3 canals merge as <br />well as the larger contributing watershed area. Data to be compiled are defined below: <br />1. The CONSULTANT will prepare a data request to SRID requesting, but not limited to: <br />a. Available measured rainfall, stage and high water mark data for the SRID. <br />b. Existing pumping/discharge records for the SRID. <br />c. As -built details for the control structures. <br />d. Existing stage data. <br />e. Existing groundwater table levels (depth to groundwater). <br />f. Build -out land use conditions. <br />The CONSULTANT will review and evaluate these data to determine their applicability to the <br />development of the surface water model described under Task 3. <br />Smith <br />A-1 <br />ATTACHMENT NO.2 <br />jj1646_Exh{bR A.docx <br />
