WORK ORDER NUMBER 9 UPPER FLORIDAN AQUIFER MODELING AND CONSUMPTIVE USE PERMIT MODIFICATION EXIMIT A SCOPE OF WORK PROJECT UNDERSTANDING Indian River County (County) operates two water treatment plants (North County and South County) and two associated wellfields (North and South) that provide potable water to the County's customers. The County currently operates under Consumptive Use Permit (CUP) No. 10524, issued by St. Johns River Water Management District (SJRWMD). The allocation in the current CUP allows for up to 6.438 million gallons per day (mgd) to be withdrawn from the North wellfield and 6.4 mgd from the South wellfield, for a total allocation of 12.438 mgd. The County anticipates that by the permit expiration date in 2032, the potable water demand will result in an increased need for 3.390 mgd of additional water, for a new total allocation of 16.228 mgd. The County has recently explored numerous options for reaching the 2032 demand, including increasing withdrawal from existing wellfields, adding new wells in the south county area, and splitting flows between the two wellfields. The County is currently in the process of investigating new water sources (APPZ/Lower Floridan Aquifer) for long-term water supply needs. In the meantime, the County wishes to revisit the option of obtaining the additional 3.390 mgd from the existing North County wellfield (9 existing wells), identifying the impacted Existing Legal Users (ELU), and preparing a well avoidance plan and mitigation strategy for future impacts, if feasible. The following Scope of Services outlines the approach to prepare the appropriate SJRWMD groundwater model, quantify impacts from the increased pumping, summarize the ELUs, conduct a well survey, and prepare an avoidance plan. Upon completion of the modeling and ELU assessment, Kimley-Horn (Consultant) will prepare the SJRWMD application for modification of the CUP. The Consultant will contract with JLA Geosciences (JLA) to serve as a subconsultant for the preparation of the groundwater modeling. The Kimley-Horn and JLA team shall be collectively referred to as the Consultant in the following Scope of Services. SCOPE OF SERVICES Task 1: Modeling Approach Memorandum (Lump Sum) The Consultant shall review CUP and groundwater data from the County and SJRWMD, including ELU facilities and allocations, SJRWMD impact evaluation criteria and historical monitoring data for water levels, water quality, and well withdrawals to form the basis of the approach for the groundwater modeling effort that will support a request for Page 1 of 6
