<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />capital cost will be about $1,292 per acre-foot. Therefore this option was rejected from further <br />consideration. <br /> <br />Alternative No.3 <br /> <br />This was the selected alternative because it represents the least cost option for accomplishing the <br />desired goals. <br /> <br />Project Description: <br /> <br />The selected option will involve mwng the modifications to the dam and appurtenant features <br />necessary to allow storage of an additional 971 acre-feet of water. This will involve elements needed <br />to provide for an increase ofnoIlIlal water surface elevation of about 3.8 feet. These elements <br />include the following: <br /> <br />1. Ftaising the main dam and auxiliary dam crest elevations by about 1.5 to 2.0 ft and adding rip <br />rap needed to protect the emban1cment below the completed nOIlIlal water surface. <br /> <br />2. UpfPrading the auxiliary dam to include internal and toe drainage, increasing the crest width, <br />adding rip rap as necessary to protect the emban1cment below the completed nOIlIlal water <br />surface and adding emban1cment to the downstream slope to flatten it to a more moderate and <br />more stable slope. <br /> <br />3. Ftaising the spillway crest level by 3.8 feet to allow for storage of the additional water. This <br />will be accomplished by increasing the height of the existing concrete weir wall as well as the <br />training and retaining walls. <br /> <br />Western Engineers, Inc. has prepared preliminary designs and cost estimates for the project. <br />Drawings showing the conceptual plans are included in Appendix C. <br /> <br />Following is a summary ofthe anticipated project cost: <br /> <br />5 <br />
