'Ihis haz been discussed with Mc Randy Clark of Select Homes,Mr.Pat McCouct <br /> of Universal Hrokerage Corporation,and Ma Michael Crowson of W6H Pacific. <br /> We Lave obsmed no sibms of instability on native slopes in Divisions [II nnd IV. Fill <br /> slopes on Divisions III and N were constructed with swttural fill wntisting of on-site granular <br /> soiis under tull-time monitoring of a qualificd individual from our firm. The structural fill is <br /> keyed into e.eisting firtn native soils and fill placed to achieve ihe final slope grades haz been <br /> propedy benched into exis[ing native materials and compaciai ro 95 percent o(MDD(mazimum <br /> dry density)acwrding to the specifications of itie AST�1 D-1557 test procedure. In addition,the <br /> lots are gradod ro slnpe au�ay from the tops of slopes and all slopes have been covered u�itL jwe <br /> matting and hydroseoded fur crosion protection. <br /> In our opinion, where slopes have been placed, compacted, graded, anJ vegr.ated az <br /> described above,the minimum building setback disiance can be reduced to 10 feet. The setback <br /> distance is�he horizontal distance meuured from the front face of ihe(ooting to ihe face of U�e <br /> slope. It should be understood that it the setFack distance is roduced to 10 feet, the risks o( <br /> losing aecess,reducing the design life of the(oundations and haring slope movement impact Uie <br /> house toundations ze incrcaaod. <br />
