Fill <br /> slopa on Divisioas iIl and N were conswaed With structural fill coacisting of on-sitc granular <br /> soils under tull-time vwniloring of a qualified individual from our firm. The swctural fill is <br /> keyed into existing fi'm native soils and fill placed to achieve the final slope grades hu been <br /> properly benched into existing native materials and compacted to 95 percent of MDD(maximum <br /> dry densiry)according to the specifiwtions otthe AST�1 Dd557 tese procedure. In addition,U�e <br /> lou are graded m slopa away Rom the tops of stopes and all slopcs have becn covend w�i�h jutc <br /> maning and hydrosealed for erosion protection. <br /> In our opinion, where siopes have been placed, compacted, graded, and vegetated az <br /> describal above,the minimum building setback distance can be redu.ed to ]0 feet. The setback <br /> diseance is�he horizontal distance meatured from the front tace o(the too�ing to the face of the <br /> slone. It should be w�derstood that if Ihe seiback Jistance is reduc� w 10 (eet, �he risks ot <br /> losing access, reducing the design li(a of the foundations and having slope movement impacl the <br /> i�ousc foundations arc incrcucd. - <br /> � <br /> / ' <br /> � <br />
