areas and provide an estimated construction cost. The cost per unit (existing home site / or buildable lot) will <br />be determined for each geographic area. <br />3. Final Ranking <br />The CONSULTANT will derive a mathematical formula and develop a spread sheet which enables a numerical <br />analysis of the following data to arrive at a Final Ranking and Prioritization of the conversion of the 30 geographic <br />areas: <br />1. Aquatic health (results of the Initial Ranking) <br />2. Sewer System Evaluation and Cost data <br />3. Estimate the Total Nitrogen and Total Phosphorus removed / Cost per Ib. removed <br />4. Public health - Availability of a Public Potable Water Utility System <br />Phase II: Master Wastewater System data <br />CONSULTANT will provide estimated average and peak flows generated by each of the 30 priority areas to the <br />COUNTY (based on 10 state standards). This information will be provided for COUNTY's inclusion in its <br />development of its Master Wastewater System. <br />Phase III — Report Preparation <br />CONSULTANT will summarize the findings of the Analysis/Prioritization, Individual Area Sanitary Sewer System <br />Evaluation, and the Master Wastewater System Evaluation in a report. The report will include a summary of the <br />approach used to determine the priority areas to be converted from onsite septic system to sanitary sewer. A <br />table of the priority rankings for the areas of the study and the estimated construction costs for each of the <br />areas will be provided as an appendix to the Report. <br />CONSULTANT will evaluate the total nitrogen (TN) and total phosphorus (TP) removed from the conversion of <br />septic to sewer for each of the 30 priority areas and compute a cost per pound for TN/TP removal. CONSULTANT <br />is to compare these cost per pound removed to other projects such as the existing Algal Turf Scrubber (Osprey <br />Marsh, Egret Marsh) projects, Spoonbill Marsh, PC main projects and any other innovative TN/TP removal <br />projects. The COUNTY will provide the CONSULTANT with TN/TP removal numbers for the projects installed <br />and operated by the COUNTY. <br />71 <br />3 <br />
