WuhioYton. lbis has been discussed with lrtr• ltandy Clark of Select Homes, Mr.Paz McCouct • of Univusal Brokerage Cocporatioa, and Mr. Michael Crowson of W&H Pacific. We have obsaved no signs of instabiliry on native slopes in Divisions III and IV. Fill slopes on Divisions III aod IV wae consavcted with stNaucal fi1��°�°�h°g of on-site granular soils uoder fnll-time monitnring of a qualified individual from our firm. 'Ibe suucwral fill is keyod inW existin8 firm neUve soils and fill placed to achieve the final slope grades has been properly benched into existing native matecials and compacted W 95 percent of MDD (maximum dry density)according to 11ie spocifications of the ASTM D-1557 test procedure. In addition,the lots are graded to slope away from the tops of slopes and all slopes have been covered w�ith i��ce matting and hydroseeded for erosion protection. In our opinion, whue slopes have been placed, compacted, graded, and vegecated as described above,the minimum building setback discance can be reduced to 10 feet. T'he suback distance is the horizontal dist�mce measured from the front face of the footing co the face of the slope. It should be understood that if the setback distance is reduced to 10 feet, the risks of losing access, reducing the desi�m life of the foundationc and having slope movement impact the house foundations are increased. � , n�;m��,n.R„ '.�yii� A�ci��.�'. ,. iond.R:;y��=: :':o mc I'i H,i:,,;.�,�„�� r.c,i.l4�l Nb6��u:n P•'!'J'.'K�[�e:P`T' •
