An integral part of this study was the formulation and <br />evaluation of alternatives for relocation of U.S. Highway 6, and the potential <br />impact this relocation would have on highway users. Step 2 investigations address <br />the critical technical issues affecting project feasibility. These technical <br />evaluations include: <br />1. Estimates of water supplies that could be utilized by the project, <br />based not only on storage of flood waters, but also on cooperation by <br />Clear Creek water users at two different levels of user participation; <br />on exchanges to meet water right calls from the South Platte; and on <br />integrated usage of existing storage reservoirs. <br />2. Estimates of the firm annual water yield that could result from each <br />of seven water supply scenarios for reservoir sizes ranging up to <br />230,000 af. Each of the seven scenarios utilizes only water native to <br />Clear Creek. However, each scenario is based on the utilization of a <br />different set of water rights. <br />3. Evaluation of two basic concepts for the relocation of U.S. Highway 6: <br />relocation inside the canyon versus relocation outside the canyon. <br />Three alternatives were identified for each of the two basic concepts. <br />Evaluation of each of these six alternatives included layout of new <br />route a 1 i gnments, construct i on costs, and ope rat i on and ma i ntenance <br />costs. The change in user costs caused by road relocation was evaluated <br />for each alternative in terms of commuting time, accident rates, and <br />vehicle operation costs. <br />4. Preparation of dam layouts, cost estimates, and construction schedules <br />for concrete-arch dams of 420, 480, and 540 feet (ft) in height, <br />corresponding to reservoir sizes of 110,000, 165,000, and 230,000 af, <br /> <br />1-4 <br /> <br />:..... <br /> <br />'-" <br /> <br />, <br />~ <br /> <br />..::;:.; <br />
