SL -9 <br />CRDA 1 Road- LS Factor - Adjacent Area <br />The LS factor for the Adjacent area is based on an average 11 H:1 V Slope and an average <br />change in elevation of 28 feet and average length of slope is 117 feet based on one flow lines located in the <br />adjacent area. The length of slope of run-off from the adjacent area was increased to a length of 172 feet <br />to make it comparable to the CRDA 1 Road area. <br />Average Length 172.0 Feet <br />Average Slope 24.0% <br />Percent Slope (S) <br />20.0% 24.0% 25.0% <br />160 5.000 6.600 7.000 <br />172.0 "LS" Factor _140JI <br />180 5.500 7.500 8.000 <br />CRDA 1 Road- LS Factor <br />The LS factor for the CRDA 1 area is based on an average 11 HIV slope with an average change <br />in elevation of 15 feet based on three flow lines cut through the area. <br />JI <br />Average Length 172.0 Feet <br />Average Slope 9.0% <br />Percent Slope (S) <br />8.0% 9.0% 10.0% <br />1.200 1.500 1.800 <br />"LS" Factor 1.560 <br />1.400 1.600 1.800 <br />Tab -9, Page 8 <br />160 <br />172.0 <br />180 <br />Revised 10/18/2016 <br />Average Length 172.0 Feet <br />Average Slope 9.0% <br />Percent Slope (S) <br />8.0% 9.0% 10.0% <br />1.200 1.500 1.800 <br />"LS" Factor 1.560 <br />1.400 1.600 1.800 <br />Tab -9, Page 8 <br />160 <br />172.0 <br />180 <br />Revised 10/18/2016 <br />Revised 10/18/2016 <br />
