<br />SYNOPSIS <br /> <br />Uinta Indian Irrigation project, and various other structures on thE <br />Duchesne River, Ashley Creek, and Brush Creek systEms. Public and <br />pr ivate power racHitie s in both basins also wool d be affected. It is <br />anticipated that agreements between present interests and pota1tial <br />project interests can be reached to mutual advantage concerning such <br />matters as correlated operation of existing and potent ial f acilit ies, <br />construction of new facilities or modification of existing structures, <br />and the acquisition of necessary right s-of-way or lands and int erests <br />in lands. <br /> <br />Economic Anal vsis <br /> <br />Construction and Operation Costs <br /> <br />The construction cost of the initial phase is est.im9.ted at <br />$204,080,000 based on DeCEmber 1949 prices. The canprehensive develop- <br />mnt construction cost is estilmted at about t>1,035,OOO,Ooo on the same <br />price base. Annual expenses for operaticn and maintenance and for <br />replacemnts over a 50-year period are estimated at $704,200 for reim- <br />bursable project features am. at $53,200 for nonreimbursable project <br />features in the initial phase and at $2,640,000 for all features in the <br />comprehensive developm9nt. The annual costs for power am. municipal <br />water features are based on current prices, while the costs for irriga- <br />tion features are based on average 1939-1944 pri~es. <br /> <br />The initial phase cost estimates are based on constructicn of <br />Soldier Creek Dam to the full height required for the comprehensive <br />development. Constructicn of this dam to ultimate heights in a single <br />operation would cost $5,240,000 more than construction to the height <br />required for the initial phase. Enlargement from initial to ultimate <br />height as a separate operation, however, would cost $8,350,000. Thus <br />one-stage construction would result in a saving of $3,110,000, equiva- <br />lent to 59 percent of the additional initial cost. The cost estimates <br />of all other project features, including Strawberry and Hasatch aqueducts, <br />are based on construction to initial phase capacity only. <br /> <br />Cost Allocations <br /> <br />The est.im9.ted construction costs of the initial phase have been <br />tentatively allocated among the various purposes that would be served <br />by the project. Costs incurred for a single purpose were assigned to <br />that purpose. Joint costs were distributed among the purposes served. <br />Allocations to flood control, considered nonreimbursable in t his plan, <br />were made by capitalizing the expected annual benefit s. The allocation s <br />made to recreation and forest resources' development, also considered non- <br />reimbursable, are equivalent to the Federal cost of the specific facHit ies. <br /> <br />11 <br />
