We have observed no signs of insubility o� native slopes in Dirisions RI and IV. Fill slopes on Divisions IR and N were wn�wcled wi�ti structural fill cotuisiug r,f en-site granular soils under Poll•time monitoring of a qualifiod individual from our ficm. 77�e strvcn:ral fill is keyed into aisting firtn native soiis and fill placed to achieve the final slope grades hzc been propedy benched into existing native materials and compacted to 95 percent of MDD(mazimum dry density)according to the specifications o(lhe ASTM D-1557 test procedure. In addition,the lots are gradod to slope aw�ay from ihc tops of slopes and ail slopes have been covered with jute maning and hydroseedeA for erosion protection. In our opinion, wAere slopes have been piaced, compacted, graded, and vegetateA as described above,the minimum building setback distanee can be reduced�0 10 feet. The setback distance is�he horiwntal distance measured from Oie front face of the tooting to the(ace of the slape. h should be understood O�at if the se!bzck distance is redu.ed �0 10 (cet, the risFs of losing access, reducing ihe design l'te of the fvmdations and having slope moecment impact J�e house foundations are increazed.
