Fill <br /> slopes on Divisioas III and N wae constructed with structural fill consisting of on-site granular <br /> soila unda full-time moniroring of a qualified individual from our firm. The structural fill is <br /> keyad into ezistiog ficm nadve soils and fill placed to achieve the final slope o ades has bcen <br /> properly benched into existing native materials and compacted to 95 percent of MDD (maximum <br /> dry deasity)according to the specificaGons of the ASTM D-1557 test procedure. In addition,tha <br /> lots aze graded to slope away from the tops of slopes and all slopes have been covered with jute <br /> matting and hydroseeded for erosic� �rote�xion. <br /> In our opinion, where slopes have been placed, compacted, graded, and vegetated as <br /> described above,the minimum building setback distance can be reduced to 10 feet. 'Ibe setback <br /> distance is tha borizontal distance measured from the front face of the footing to the face of the <br /> slope. It ahould be understood that if the setback distance is reduced to 10 feet, the risks of <br /> losing ar:ess, reducing the d�ign life of the foundations and 6aving slope movement impact the <br /> house .• dations aze increased. <br /> GeoEngineers,Inc. <br /> 8410 154th Avenue Y.E. <br /> Redmond,WA 9�52 <br /> � 'I�lephone(2W)861-(000 <br /> Fax(20G)8616050 <br /> RinW m rny0ed D+ve�. . . <br />
