Fiil <br />slopes on Divisions III and IV were consavcted with suuctural fill consisting of on-site granulaz <br />soils under fu11-time moniWring of a qualified individual from our ficm. The stiuctural fill is <br />�eY� �� ��Wg firm native soils and fip placed tc .ichieve the final slope grades has been <br />properly benched into existing native materials and compacted to 95 percent of I�IDD (mazimum <br />dry density) accarding to the specifications of the ASTM D-1557 test procedure. In addition, the <br />lou ate graded to slope away from the tops of slopes and al� slopes have been covered with jute <br />matting and hydroseaded for erosion protection. <br />In our opinion, where slopes have been piaced, compacted, graded, and vegetated as <br />described above, the minimum building setback distance can be reduced to 10 feet. The setback <br />distance is the horizontal distance measured from the front face of the footing to the face of the <br />�'�pe. It should be understood that if the setback distance is reduced to 10 feet, the risks of <br />losing access, teducing the design life of the foundations and 5avin� slope movement impaM tt�e <br />house foundations ue increased. <br />GmEnginmrs, inc. <br />KfIO 154ih Arcrmc N.F.. <br />Redmond,�'d 98052 <br />Tclephonc (2W) 3GI�i000 <br />Far (206) 861-GOSO <br />naim �, �a��i�a wce�. <br />
