This haz been discussed with Mr. Randy Clazk of Select Homes, Mr. Pat McCouR of Universal Brokerage Corporation, and Mr. Michad Crowson of W&H Pacific. We have observad no signs of iastability on native siopes in Divisioas III and IV. Fill slopes on Divisioac III and N wae ooathuctod with structural fill consisting of on-site granular soils under full-time monitoring of a qualified individual fram our firm. 71�e structural fill is keyad into existing firm native soils and fill placed to achieve the final slope grades 6az been proQuly benched into existing native materials and compacted to 95 percent of MDD (maximum dry deosity)according to the specifications of the ASTM D-1557 test procedure. In addition,the lots are graded to slopa away from the tops of slopes and �ll slopes have been covered with jute matting and 6ydroseeded for erosion protection. In our opinion, where slopes have beer. placed, compacted, graded, and vegetated as described above, the minimum building setback distance can be reduced to 10 feet. The setback distance is the horizontal distance measured froin the front face of the footing to the face of the slc+,�e. It should be understood that if the setbrick distance is reduced to 10 feet, the risks of l�sing access, reducing the design life of the foundations and having slope movement impact the house foundations aze increaSed. . .._>�nd.'�\; �..�i:_ .. ._ ,�,� _ . ��,�., i . . /
