This has been discussod with Mr. Randy Clazk of Seled Homes, Mr. Pat McCouR of Univasal Brokerage Co�poration, and Mr. Michael Crowson of WdcH Pacific. We have obsaved no signs of instability on native slopes in Divisions III and N. Fill slopes on Divisions III and IV were const:uctod with structural fill consisting of on-s3te granular eoils under full-time monitoring of a qualified individual from our firm. 'Ite swcwral fill is keyed 'wto acisting firm native soils and fill placad to achieve the final slope grades has been properly benched into ezisting native materials and compacted to 95 percent of MDD(maximum dry density)according to the specificadons 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 with jute matting and hydroseeded for erosion protection. In our opinion, where slopes have been p�acad, compaaed, graded, and vegetated as describod above, the minimum building setback:listance can be reduced to 10 feet. The setback distance is the horizontal distance measurad from the front face of the footiag to 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 design life of the foundations xnd having slope movement impact the house foundations are increased. , ,..��. .�� .
