4. MOUND SIZING <br /> A. Calculate Clean Sand Lift: 3 feet minus Depth to Limiting Condition (1.C) = Clean Sand Lift (1 ft minimum) <br /> 3.0 ft - 1.8 ft = 1.2 ft Design Sand Lift (optional): <br /> B. Calculate Upslope Height: Clean Sand Lift (4.A) +media depth (1 ft.) +cover (1 ft.) = Upslope Height <br /> 1.2 ft + 1.0 ft + 1.0 ft= 3.2 ft <br /> D-34:Slope Multiplier Table <br /> Land Slope 4 0 1 2 3 4 5 6 [ 7 8 I 9 10 II 12 13 14 15 16 17 - I8 19 20 21 22 23 24 25 <br /> Upslope 13:1 3.00 2.91'2.83 2.75 2.68 2.61 2.54 2.48 2.42 2.36 2.31 2.26 2.21 2.17 2.13 2.09 2.06 2.03 2.00 1.97 1.35 1.93 1.31 1.89 1.87 1.85 <br /> 69113 Ratio 4:1 4.00,3.85 3.70 3.57 3.45 3.33 3.23 3.12 3.03 2.94 2.86 2.78 2.70 2.62 2.55 2.48 2.41 2.35 2.29 2.23 2.18 2.13 2.08 2.03 1.99 1.93 <br /> Land Slope% 0 1 2 3 4 5 6 7 8 9 ID 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 <br /> GOt7nslOpe 3:1 3.00 3.09 3.19 3.30 3.41 3.53 3.66 3.80 3.95 4.11 4.29 4.48 4.69 4.95 5.24 5.55 5.88 6.24 6.63 7.04 7.47 7.93 8.42 8.93 9.46 10.02 <br /> Berm Ratio 4:1 4.00 4.17 4.35 4.54 4.76 5.00 5.26 5.56 5.88 6.25 6.67 7.14 7.69 8.29 8.92 9.57 10.24 10.94 11.67 12.42 13.19 13.99 14.82 15.67 16.54 17.44 <br /> Select Upslope Berm Multiplier <br /> C. <br /> (based on land slope): 3.12 (figure D-34) <br /> D.
