G. MOUND SLOPE WIDTH&LENGTH(Greater than 1%) <br /> 1. Dovmslope 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 - 2 ft= 1 feet <br /> b.Mound height at the upslope edge of rock layer=depth of dean sand for separation(G2a) <br /> at upslope edge plus depth of rodc tayer(1 foot)to depth of cover(1 foot) <br /> 1 ft+1ft+1 ft= 3 feet <br /> c.Upslope berm multiplier based on land slope(see figure D-34) <br /> Select bertn multiplier of 2.94 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.94 x 3 ft = 9.0 feet <br /> DOWNSLOPE <br /> e. Drop in elevation=rodc layer width(D2)times percent landslope(C5)1100 <br /> 10 ft x 9 °� /100= 0.9 feet <br /> f.DoHmslope mound height=depth of dean sand for slope diffe�ence(G2e) <br /> at downslc�pe rodc edge plus the mound height at the upslope edge of rodc layer(2b) <br /> 0.90 ft + 3 ft= 3.9 feet <br /> g.Doumslope berm multiplie.r based on percent land slope(see Figure D-34) 5.18 <br /> h.Doumslope width=dovmsiope multiplier(G2g)times dovmslope mound height(G2fl <br /> 5.18 x 3.9 = 21.0 feet <br /> i.Select greater of G1 and G2h as the downslope width 21.0 feet <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus dovmslope width(G2i) <br /> 9.0 ft+ 10.0 ft+ 21.0 ft= 40.0 feet <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length(D3) <br /> plus upslope width(G2d) <br /> "�"`'�`� 9.0 ft + 75.0 ft+ 9.0 ft= 93.0 feet <br /> Qvwn� SLo'� �S I'T 75 �=t /S FT /U`" ���e' <br /> Final Dimensions (slope>1%) 40.0 ft x 93.0 ft <br /> I hereby certify that I have completed this work in acxordance with all applicable ordinances, rules and laws <br /> / L��' <br /> ,,/�� (signature) 810 (license#) /D�iG ��>—(date) <br /> P e2of6 <br />
