<br />,- <br /> <br />Ms. Honey R. Moschetti <br /> <br />-2- <br /> <br />December 22, 1995 <br /> <br />Task I-Identity Alternative Dam Safety Modification Concepts. We will evaluate potential dam safety <br />modification concepts and, with the concurrence of the Reservoir Company, select up to three alternatives <br />for feasibility evaluations. At this time we envision that the following three alternatives would be studied: <br /> <br />Alternative No.I- Rehabilitation of the existinll crest structure, including repair and rehabilitation <br />of the concrete and anchorage to the original dam section. <br /> <br />Alternative No.2 - Replacement of the 12-foot crest raise section with a new concrete section. <br /> <br />Alternative-No~No~ction. 'ThiS'1llternative~1I consider the potential consequences that might <br />result from not repairing the dam. These consequences would be expected to include a permanent <br />reservoir restriction imposed by the SEO, and the resulting loss of reservoir storage. <br /> <br />Task 2 - Develop Feasibility Designs of Alternatives. Feasibility designs of the alternative modification <br />conccpls will be developed for the three alternatives selected in Task I. ll1ese designs will bc developed <br />10 a level sufficient to establish their technical and economic feasibility, and will includc appropriate <br />analyses and illustrative drawings. <br /> <br />Task 3 - Develop Project Cost Evaluations. For each Illternative studied, GEl will develop estimates of <br />project costs, including opinions of probable design, construction administration, and construction costs. <br />We will also evaluate potential advantages and disadvantages (both technical and economic) of each <br />alternative. Project costs developed in this task are expected to be suitable for use in project budget planning <br />and for pursuit of project financing options. <br /> <br />Task 4 - Prepare Draft Report. We will prepare a Draft Feasibility Report summarizing the work <br />described in Tasks 1,2, and 3. This report will identifY a preferred alternative to be carried into final design <br />and construction. The selection of the preferred alternative will be made with the concurrence of the <br />Reservoir Company. ' <br /> <br />The Draft Feasibility Report will also include a discussion of potential pennitting issues related to final <br />design and construction of the project, such as SEO review and approval, and state and federal permit <br />requirements. <br /> <br />The Feasibility Report will be prepared in accordance with CWCB guidelines in anticipation of the Reservoir <br />Company's application to the CWCB for project funding through the Construction Loan Fund. <br /> <br />Task 5 - Reservoir Company and CWCB Review. We will present the Draft Feasibility Repon to the <br />Reservoir Company for review and comment. After incorporating the Reservoir Company's comments, we <br />will present the draft report to the CWCB for review and comment. <br /> <br />Task 6 - Prepare Final Report. Following review by the Reservoir Company and the CWCB, GEl will <br />finalize the Feasibility Repon to incorporate all review comments. The final repon will then be slIbmiued <br />to the Reservoir Company and the CWeB. We will also submit a copy of the final report to Mr. Mike <br />Graber with the SEO in Pueblo to keep him apprised of the Reservoir Company's progress toward resolving <br />the dam safety issues at DeWeese Dam. . <br />
