F. ABSORPTIOA WIDTH � Absorption ratio: r 2-� <br /> 1. AbsorpGon width equals absorption ratio times rock layer width <br /> 2.p0 x 10.0 ft = 20.0 ft <br /> G. MOUND SLOPE WIDTH 8�LENGTH(Greater than 1°k) <br /> 1. Downslope abso�ption width=absorption width minus rock layer width <br /> 20.0 feet - 10.0 feet= 10.0 ft <br /> 2. Calculate mound size � <br /> UPSLOPE <br /> a.Depth of clean sand at upslope edge of rock layer=3 feet minus distance to resVicting layer(C1) <br /> 3.0 ft - 2.0 ft= 1.0 ft <br /> b.Mound height at the upslope edge of rock layer=depth of clean sand for separation(G2a) <br /> at upslope edge plus depth of rock layer(1 foot)to depth of cover(1 foot) <br /> 1 ft+1ft+1 ft= 3.0 ft <br /> c.Upslope berm mulGplier based on land slope(see figure D-34) <br /> Selected berm multiplier: 2.70 <br /> d.Upslope width=berm multiplier(G2c)times upslope mound height(G2b): <br /> 2.70 x 3.0 ft = 9.0 ft <br /> DOWNSLOPE <br /> e.Orop in elevation=rock layer width(D2)times percent landslope(C5)1100 <br /> 10.0 ft x 12.0 °/a I 100= 1.2 ft <br /> f.Downslope mound height=depth of clean sand for slope difference(G2e) <br /> at downslope rock edge plus the mound height at the upslope edge of rock layer(2b) <br /> 1.2 ft + 3.0 ft= 4.2 ft <br /> g.Downslope berm multiplier based on percent land slope(see Figure D-34 <br /> Selected berm multiplier: <br /> h.Downslope width=downslope multiplier(G2g)times downslope mound height(G2f} <br /> 0.00 x 4.2 = 0.0 ft <br /> i.Select greater of G1 and G2h as the downsiope width 10.0 ft <br /> j.Total mound width is the sum of upslope(G2d)width plus rock layer width(D2)plus downslope width(G2i) <br /> 9A ft+ 10.0 ft+ 10.0 ft= 29.0 ft <br /> k.Total mound length is the sum of upslope width(G2d)plus rock layer length(D3)plus upslope width(G2d) <br /> 9.0 ft + 29.0 ft+ 9.0 ft= 47.0 h <br /> Final Dimensions (slope>1%) 29.0 ft x 47.0 ft <br /> I hereby certify that ail work has been completed in accordance with all appticable ordinances,Nles&laws. <br /> (signature) 8�U(�icense#) �U / b (date) <br /> Page 2 of 5 <br />
