This has been discussed with Mr. Randy Clark of Select Homes, Mr. Pat McCourt <br />of Universal Brokerage Corporation, and Mr. Michael Crowson of \Y&H Pacific. <br />We have o6servai no signs of instability on native slopcs in Divisions I[I and N. FiII <br />slop� on Divisions III and IV were canstructed with structural fill consisting of omsite granular <br />soils under full-time monitoring of a quali�ed individual from our firm. The stcuctural fill is <br />keyed ir.�o azisting firm nativc soils and fill placcd to achieve the final slope grades has been <br />pcoperly benchal into ezisting native materials and compacted to 95 percent of MDD (maximum <br />dry density) according w lhe specifications of ilie ASThi D-I557 test proceclure. In addition, the <br />lots ace gradecl to slope away trom the tops of slopes and all slopes have been covered with j�te <br />matting and hydrosealed for erosion protection. <br />In our upinion, where slopes have been placed, compactecf, grad�, and vegetated as <br />described above, the minimum building setback distance can be reciuced to 10 Ceet. The setback <br />distance is the horizontal distance measured from the fmnt face of tl�e footing to the face of tt�e <br />slope. It should be undersrood that if ilie setback disGlnce is reclucal to 10 feet, the ris}•s aC <br />losing access, reducing the design life of the foundations and having slope movement impact the <br />house foundations are increased. <br />GcnEngimrrs, Inc. <br />S�iIU 154th Aecnuc `.I�. <br />Nivhnond,IX'A 980>? <br />Tcluphonc (206) 8(il-Gu�, � <br />F;u ('OG) kl(i1�i050 <br />r,��v � �-. .�, . �.. <br />
