Page 2 of 5 <br />Hydraulic Modeling: As part of the analysis, several modeling scenarios were evaluated. Those scenarios <br />are detailed in the report under Hydraulic Analysis. The hydraulic analyses were divided into four (4) <br />specific scenarios based on existing and proposed flow rates. <br />Scenario A — Current Delivery: <br />These flows were based on a one year snap shot of what IRCDUS has delivered. <br />Scenario B — Flows to Barrier Island Communities within the IRCDUS service area plus John's Island: <br />The consultant evaluated all the existing Consumptive Use Permits (CUPs) within the IRCDUS <br />service area and included the allocated amounts from the CUPs. For areas that did not have a <br />CUP, the consultant assumed 1 million gallons per year to irrigate one acre. Also included in this <br />scenario is the requested demand of 1 million gallons per day (mgd) for John's Island. These <br />allocations are detailed under Appendix B of the report. <br />Scenario C — Flows to Barrier Island Communities within the IRCDUS service area plus John's Island plus a <br />portion of City of Vero Beach Service Area: <br />The difference in this Scenario versus Scenario B is the addition of The Shores and Carlton River <br />Club. <br />Scenario D-- Maximum Capacity of System: <br />In this scenario, minimum flows were allocated as done in Scenario C. The only difference is that <br />additional demands were placed at different locations until system pressures fell below <br />minimum criteria. The purpose of this scenario was to evaluate the maximum capacity that could <br />be delivered given some of the existing infrastructure, proposed infrastructure, and proposed <br />assumptions. <br />The below graphical representation outlines the above scenarios. <br />Graphical Representation of the Scenarios <br />5 <br />4.5 <br />4 j 3.5 <br />L 2.5 <br />< 2 <br />1.5 <br />1 <br />0.5 <br />0 <br />MIMI WWI MO IMITL. <br />Lri =I <br />MMININIMMEININ <br />A <br />g Scenario c <br />x North BI = JI % COVB <br />D <br />C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@B80DD750\@ BCL@B80DD750.docx <br />145 <br />
