Minimum <br /> <br />Excavate the majority of Area L to a minimum depth of 3 feet <br />(60,000 cY) <br />*Site preparation and disposal on Site #2 (43,560 CY) <br />*Site preparation and disposal on Site #3 (14,500 CY) <br />River Diversion <br /> <br />$186,000 <br /> <br />$57,545 <br />$19,315 <br />$50,000 <br /> <br />Plus 28% overhead <br /> <br />$312,860 <br />$87,6OO <br /> <br /> $400,460 <br />This project buys roughly 20 years before the bedload situation is equivalent <br />to today. If less work than what is described above is done, the costs of the <br />project probably out way the benefits. <br /> <br />*Disposal site preparation includes stripping top soil, spreading the <br />sediment, replacing top soil, and reseeding. <br /> <br />Mid Range <br /> <br />Excavate 90,000 CY from Area L making majority of this <br />area between 3 and 4 feet deep. <br />Excavate Area K to a minimum depth of 3 feet (3,500 CY) <br />Excavate Area C to a minimum depth of 3 feet (13,500 CY) <br />Excavate channel & sedimentation basin in Area I <br />(2,000 CY trucked to a site away from the lake) <br />Site preparation and disposal Site #1 (25,000 CY) <br />Site preparation and disposal Site #2 (43,560 CY) <br />Site preparation and disposal Site #3 (14,500 CY) <br />Site preparation and disposal Site #4 (13,500 CY) <br />Trucking to Site #1 <br />River diversion <br /> <br />$279,000 <br /> $10,800 <br /> $22,950 <br /> $18,800 <br /> <br />$32,000 <br />$57,545 <br />$19,315 <br />$18,090 <br />$77,500 <br />$50,000 <br /> <br />Plus 28% overhead <br /> <br />$586,000 <br />$164,080 <br /> <br />$750,080 <br /> <br />This option should last for 30 years; a reasonable amount of time. In <br />addition, it provides a direct benefit to all portions of the lake and addresses <br />all of the areas recommended as priorities. <br /> <br />If Site #1 can be utilized without reloading material into on-road trucks, the <br />total cost for this option can be reduced by approximately $100,000 including <br />overhead. Staff feels overhead in general can be reduced. <br /> <br />f:\shrdocXb&z\stever\lakoagda.doc <br /> <br /> <br />
