<br />COST ESTIMATES <br /> <br />C) <br /> <br />o <br /> <br />(-, From the preliminary design drawings, reconnaissance-level estimates of construction <br /> <br />O':l <br />,,",," quantities and unit construction prices have been made. Construction quantities, prices and <br /> <br />en allowances have been combined to obtain an estimated total construction cost. Costs are indexed <br /> <br /> <br />to January 1986. Future Inflation is not Included. To determine the funding necessary to complete <br /> <br />the project, additional elements of project administration and financing costs have been added to <br /> <br /> <br />obtain the total investment cost. Summaries of estimated investment costs are presented in Tables <br /> <br />S.4 and S.5. <br /> <br />Comparison of alternative reservoirs and combinations of reservoirs for this Study is based <br /> <br />on estimates of debt service and average annual operating costs. The costs are comprised of the <br /> <br />yearly principal and Interest payment (debt service) on assumed 30-year, 8 percent financing of the <br /> <br />total Investment cost and the estimated average annual cost of pumping power, operating <br /> <br />personnel, maintenance and repair costs. No price escalation was incorporated. Financing and <br /> <br /> <br />reserve includes 3 percent for initial costs of financing and a reserve of one-years debt service. No <br /> <br />separate allowance was included for environmental mitigation. A summary of yearly debt service <br /> <br /> <br />and average annual operating costs is presented In Table S.6. The relative costs among alternatives <br /> <br />have been based on this average total cost per year. <br /> <br />t',: <br />~,.; <br /> <br />'. <br /> <br />ALTERNATIVE COMPARISONS <br /> <br />Single reservoirs in this Study were analyzed for their ability to meet Joint-Use Reservoir <br /> <br />objectives. These single reservoirs and combinations of reservoirs were also analyzed for their <br /> <br /> <br />ability to supply the greater yields necessary to meet Replacement Reservoir objectives based upon <br /> <br /> <br />the yield of Green Mountain Reservoir. A reservoir could initially serve as a Joint-Use Reservoir, and <br /> <br /> <br />later, in combination with additional reservoir(s), also serve as a Replacement Reservoir of the <br /> <br />Exchange Project. <br /> <br />JOINT-USE RESERVOIR PROJECT: Yields from Wolford Mountain A' and C, Red Mountain <br /> <br /> <br />and Azure Reservoirs appear to be within range of the objective 30,000 af of annual yield for a Joint- <br /> <br />Use Reservoir. Comparative unit cost of yield for the Joint-Use Reservoirs is presented in Table S.7. <br /> <br />16 <br />
