G. MOUND SLOPE WIDTH 8 LENGTH(Greater than 19�0) <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 clean sand at upslope edge of rock layer=3 feet minus distance to restricting layer(C1) <br /> 3 ft - 1.4 ft= 1.6 feet <br /> b. Mound height at the upslope edge of rock layer=depth of clean sand for separation(G2a) <br /> at upsfope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1.6ft+ 1ft+1ft= 3.6 feet <br /> c. Upslope berm multiplier based on land slope(see flgure D-34) <br /> Select benn multiplier of 3.12 <br /> d. Upslope width=berm multiplier(G2c)ames upslope mound height(G2b): <br /> 3.12 x 3.6 ft = 11.0 feet <br /> DOWNSLOPE <br /> e. Drop in elevation=rodc layer width(D2)times per�ent landslope(C5)1100 <br /> 10 ft x 7 % I 100= 0.7 feet <br /> f. Downslope mound height=depth of dean sand for siope difference(G2e) <br /> at downslope rodc edge plus the mound height at the upslope edge of rock layer(2b) <br /> 0.70 ft + 3.6 ft= 4.3 feet <br /> g.Downslope berm multiplier based on percent land slope(sae Figure D-34) 5.56 <br /> h. DoNmslope width=dovmslope multiplier(G2g)6mes downslope mound height(G2� <br /> 5.56 x 4.3 = 23.0 feet <br /> i.Select greater of G1 and G2h as the downslope width 23.0 feet <br /> j.Total mound width is the sum of upslope(G2d)width plus rodc layer width(D2)plus dovmslope width(G2i) <br /> 11.0 ft+ 10.0 ft+ 23.0 ft= 44.0 feet <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length (D3) <br /> plus upslope width(G2d) <br /> 11.0 ft + 62.0 ft+ 11.0 ft= 84.0 feet <br /> Final Dimensions (slope>1%) 44.0 ft x 84.0 ft <br /> I hereby certify that I have completed this work in accordance with all applicable ordinances, rules and laws <br /> ,,:�� (signature) 810 (license#) /V�v��/c3 (date) <br /> P e2of6 <br />
