order to evaluate accessibility, proximity to neighboring properties and proximity to floodplains. Finally, the Engineer will use existing FEMA Flood Insurance Rate Map ( "FIRM ") data to map the location of the floodplain relative to proposed locations of water reuse facilities. 1.4.2 Conceptual Layout of Infrastructure. Review identified limitations to each alternative identified as part of subsection 1.4.1 above and refine alternatives to reduce impacts to the extent practical. The Engineer will utilize conceptual schematics of the alternatives to provide the basis for the development of a water reuse delivery system. 1.4.3 Reuse Water Design Parameters. Develop potential design parameters for a reuse water utility. The conceptual plan and design will be introduced to stakeholders in public meetings to receive comments and to gauge public acceptance. 1.4.4 Reuse Water Chemistry Profile Development. Collect one (1) grab sample of the effluent from the City's wastewater treatment plant for analysis for suitability in industrial applications, such as cooling applications. This chemical analysis of effluent by the Engineer is for parameters that are not otherwise conducted as part of the routine testing and reporting requirements of the City's discharge permit, and may include minerals and dissolved gases. The Engineer will use the results of this analysis to develop probable costs for treatment of boiler make -up water to minimize corrosion and scaling potential. 1.5 TASK 5 — ALTERNATIVE COST EVALUATION The Engineer will: 1.5.1 Develop preliminary opinions of probable construction costs for expansion of the city's water reuse system using the results of the conceptual planning and design detailed in Section 1.4 above. In addition the Engineer will develop projected annual water reuse system operations and maintenance costs. 1.6 TASK 6 — ECONOMIC ANALYSIS The Engineer will: 1.6.1 Analyze the potential economic benefits of expanding the existing water reuse system relative to other water supply alternatives that could be implemented by the City and University. In this analysis, the Engineer will identify the degree to which two water reuse alternatives are cost - effective and describe the potential economic benefits that could be realized after implementation. The Engineer will include: a) A comparison of the present value of the range of costs and quantifiable benefits; b) The projections of the relative economic impact of additional water as it relates to minimizing water supply costs for future demands; and. c) A cost comparison of water supply alternatives that may satisfy the same demand as the proposed reuse project. Water supply alternatives are limited to: i) increased raw water purchases from GBRA; Direct Water Reuse Feasibility Study 2012 — Espey
