G. MOUND SLOPE WIDTH 8 LENGTH(Greaterthan 1%) <br /> 1. Downslope absorption width=absorption width minus rock layer width <br /> 20 feet - 10 feet= 10 feet <br /> 2. Calculate mound size <br /> UPSLOPE <br /> a. Determine depth of dean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1) <br /> 3 ft - 1.6 ft= 1.4 feet <br /> b. Mound height at the upslope edge of rock layer=depth of clean sand for separation (G2a) <br /> at upsiope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1.4ft+ 1ft+ 1ft= 3.4 feet <br /> c. Upslope berm multiplier based on land slope(see figur�D-34) <br /> Select bemi multiplier of 2.94 <br /> d. Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.94 x 3.4 ft = 10.0 feet <br /> DOWNSLOPE <br /> e. Drop in elevation=rock layer width(D2)times percent landslope(C5)/100 <br /> 10 ft x 9 % I 100= 0.9 feet <br /> f. Downslope mound height=depth of dean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 0.90 ft + 3.4 ft= 4.3 feet <br /> g. Downslope berm multiplier based on percent land slope(see Figure D-34) 6.25 <br /> h. Downslope width=downslope multiplier(G2g)times downslope mound height(G2� <br /> 6.25 x 4.3 = 26.0 feet <br /> i. Select greater of G1 and G2h as the downslope width 26.0 feet <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus dovmslope width(G2i) <br /> 10.0 ft+ 10.0 ft+ 26.0 ft= 46.0 feet <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length (D3) <br /> plus upslope width (G2d) <br /> 10.0 ft + 62.5 ft+ 10.0 ft= 82.5 feet <br /> Final Dimensions (slope>1%) 46.0 ft x 82.5 ft <br /> I hereby certify that I have completed this work in accordance with all applicable ordinances, rules and laws <br /> �� (signature) 810 (license#) /��r�a_/,�� _(date) <br /> � <br /> P e2of6 <br />
