<br />Drainage Assumptions: Repairs assume clearing material from the ditches and basins, erosion repair,
<br />minor grading, and surveying. Assumed the ditch and basin areas will require repair to a depth of 1-foot, by
<br />excavating sediment fill down to original grades and / or filling in areas where erosion occured. Assumed 1/2
<br />of the repair area will require excavation and 1/2 of the repair area will require fill.
<br />Perimeter Drainage Ditch:
<br />Total Ditch Length = L = 10,745 feet (ft)
<br />Assumed Average Ditch Width = W = 10 ft
<br />Surface Area = (L x W) = (10,745 ft) x (10 ft) = 107,450 sf = (107,450 sf) x (1 sq.yd / 9 sf) = 11,939 sy
<br /> = (107,450 sf) x (1 acre / 43,560 sf) = 2.5 acres
<br />Sediment / Erosion Volume = (11,939 sy) x [(1-ft depth) x (1 yd / 3-ft)] = 3,980 cy
<br />Basin Area:
<br />Basin 1 Area = 8.5 acres / Basin 2 Area = 1.5 acres / Basin 3 Area = 2.5 acres
<br />Total Basin Area = (8.5 ac + 1.5 ac + 2.5 ac) = 12.5 acres = (12.5 acres) x (43,560 sf / 1 acre) = 544,500 sf
<br /> = (544,500 sf) x (1 sy / 9 sf) = 60,500 sy
<br />Sediment / Erosion Volume = (60,500 sy) x [(1-ft depth) x (1 yd / 3-ft)] = 20,167 cy
<br />Repair Volumes:
<br />Total Repair Volume = (3,980 cy + 20,167 cy) = 24,147 cy
<br />Soil Excavation Volume = (24,147 cy) x (1/2) = 12,074 cy
<br />Soil Fill Volume = (24,147 cy) x (1/2) = 12,074 cy
<br />Total Area Requiring Grading / Surveying:
<br />= (11,939 sy + 60,500 sy) = 72,439 sy
<br />= (2.5 acres + 12.5 acres) = 15 acres
<br />Final Cover Assumptions: The Total Final Cover Area = 674 acres. Assumed 10% of Final Cover Area will
<br />require repair to a depth of 1-foot, by excavating sediment fill down to original grades and / or filling in areas
<br />where erosion occured. Assumed 1/2 of the repair area (1/2 x 10% = 5%) will require excavation, and 1/2 of
<br />the repair area (1/2 x 10% = 5%) will require fill.
<br />Repair Area Calculations (various units):
<br />Total Final Cover Area = 674 acres
<br />Total Area to Be Repaired = (674 acres) x (10%) = 67.4 acres
<br /> = (67.4ac) x (43,560 sf / 1 acre) = 2,935,944 sf
<br /> = (2,935,944 sf) x (1 sy / 9 sf) = 326,216 sy
<br /> = (2,935,944 sf) / (1,000 sf / M.S.F.) = 2,936 MSF
<br />Excavation Area = (1/2) x (67.4 acres) = 33.70 acres
<br /> = (33.70 ac) x (43,560 sf / 1 acre) = 1,467,972 sf
<br />Fill Area = (1/2) x (67.4 acres) = 33.70 acres
<br /> = (33.70 ac) x (43,560 sf / 1 acre) = 1,467,972 sf
<br />Soil Repair Volumes:
<br />Soil Excavation Volume = (1,467,972 sf) x (1-ft) x (1 cy / 27 cf)] = 54,370 cy
<br />Soil Fill Volume = (1,467,972 sf) x (1-ft) x (1 cy / 27 cf)] = 54,370 cy
