<br />around the entire lake perimeter to avoid flooding neighboring properties. In addition, a very large <br />pumping facility would be needed to fill the reservoir. <br /> <br />SELECTED ALTERNATIVE <br /> <br />Alternative 2, Lake Bottom Excavation in Conjunction with Earth Fill at an Adjacent Property, was <br />selected as the preferred alternative. This alternative consists of excavated material from the lake <br />bottom to form additional storage. A compacted earth slope liner will be constructed around the <br />excavated area to control seepage. Preliminary drawings of this alternative are included in a pocket at <br />the end of this study. <br /> <br />COST ESTIMATE <br /> <br /> SUB.CONTRACTOR COST COMP ARlSON SHEET <br /> Bid Type: Budget Proposal Project Title: Kern Reservoir <br /> Project Manager: Ed Lafferty Contractor <br />Item Description ofltem Quantity Unit Unit Cost Item Cost <br /> Mobilization I LS $40,300.00 $40 300.00 <br /> Demobilization and Clearin. <br /> Erosion Control <br /> Silt Fence 13,000 LF $1.08 $14,040.00 <br /> Vehicle Trackin.
