N ~ C'? CHAPTER VII FINANCIAL ANALYSIS Fish and wildlife benefits. the project would result in total $2,010. The Fish and Wildlife Service estimates annual fish and wildlife benefits of Recreational benefits. No recreational benefits are claimed from project development. The costs required to obtain the recreational benefits evaluated by the National Park Service, exclusive of fish and wildlife benefits, would exceed the benefits. Summary of benefits. The direct and indirect benefits anticipated from the project are summarized in the followine tabulation. Direct Annual Value Indirect Total Irrigation $93,100 $77,700 $170,800 2,010 $172,810 Fish and wildlife Total Benefit 2,010 $95,110 $77,700 Annual Equi valen t Co sts Construction costs. An annual amount of $87,200 would be required annually to amortize the project construction cost over a 100-year period at 2.5 percent interest. In determining this amount allowances were made for interest during construction and the present worth of items that could be salvaged at the end of the lOO-year period. Operation, maintenance, and replacement costs. Approximately $5,850 would be required annually over the 100-year period of analysis for operation, maintenance, and replacements of project features. For the determination of annual equivalent costs, the replacement costs were computed on a sinking fund basis at 2.5 percent interest over a lOo-year period. Assignment of Colorado River storage project costs. Approximately G13,600 annually would be assigned to the Silt project as its prorated share of the cost of regulatory features of the Colorado River Storage project. Costs of the storage project's regulatory features would be paid by revenues of the storage project. They are, however, being assigned for purposes of benefit-cost analyses to future water-consuming projects in the upper basin since development of such projects is depend- ent on the river regulation that would be provided by the storage project. 50
