Soil requirements for final cover (cubic yards) <br /> LAYER SECONDARY SITE PRIMARY SITE TOTAL <br /> FOUNDATION 16, 133 145,200 161,333 <br /> CLAY 16, 133 145,200 161, 333 <br /> VEGETATIVE 16, 133 145,200 161, 333 <br /> TOTAL 48,399 435,600 484,000 <br /> * Unit Costs for Placement <br /> * Vegetative layer cover -- 1.0 ft. thick. Assuming excavation <br /> and placement at 138 c.y. /hr. , and using labor costs at $23 .58 <br /> plus scraper operation cost of $60. 10, the following unit cost <br /> calculation applies: <br /> Unit cost ($23 .58 + $60. 10) /138 c.y. /hr. _ $0.61/c.y. <br /> * Clay, Foundation cover -- 1. 0 ft. thick. The excavation and <br /> placement unit cost will be the same as for the Vegetative <br /> Layer. However, the clay and foundation materials will <br /> require a greater compactive effort for CQA compliance and <br /> will require an additional unit expense as shown in the table <br /> on p. 18. <br /> * Cost to import clay from Ione. Assuming a mix ratio of 20% <br /> Ione clay for the one foot clay barrier layer. <br /> Total soil required for clay layer = 161, 333 c.y. <br /> 20% of 161, 333 = 32,266 c.y. <br /> Cost to deliver clay from Ione = $ 7. 50/c.y. <br /> (32, 266 x $ 7.50 ) _ $242, 000 <br /> 17 <br />
