We hrve obsaved oo signs of instability on aative alopes in Divisions III and IV. Fill slopes on Divisions IIi ind IV wae constiuctod with suuctura] fill consisting of on-site granulaz aoils undu tull-time monitoring of a qualified individual from our firm. 'It�e suuctural ffi� �s Icoyed into existing firm native soils and fill placed to achieve the fina] slope grades has been properly benched into ezisting native materials and compacted to 95 percent of MDD (maximum dry deatity) accotding to the specificadons of the ASTM D-1557 test procedure. In addition, the lots are graded to si�pe away from the tops of slopes and all slopes have baen covered with jute matting and hydroseeded for erosion protection. In our opinion, where slopes 6ave been pla^ed. comPactal, Braded, and vegetata. at described above, the minimum building secback distance can be reduced to 10 feet. Thz setback distance is the horizontal distance measured from the front face of the footing to the face of the siope. 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 and having slope movement impact the house foundations are increased. r��,�'r:�,:,�,�s, �n ..,;.� . ,a� anr,... � E. ked•�:l..�td.1A�d ��^� lcu.� :' ��:'n I= x, � 2n�.n�. n�n. �llA �:"1�I 56�+�o:n �...� . ,., ....
