'lhis hu been discussed wiih Mr. Randy Clazk of Select Homes, Mr. Pat McCourt ' of Uaivusal Brokexage Co�poration, and Mr. Michael Crowson of W&H Pacific. We 6ave obsavad � aigns of inshbility on oative siopes in Divisions III and IV. Fill alopes on Divisioas III and N wae coastruccod with strvaural fiil coasisdng of on-site granular eoila unda full-time monitoring of a qualified individual hom our firm. 'Ibe stiuctural fill is keyad into existing ficm native soils snd fill placed to achieve the final slope grades has been propuly benchod into existing native materials and compacted to 95 percent of MDD (maximum dry deosity)accotding W the specifications of the ASTi�i ll-1557 test procedure. In addition,the lots a:^graded to slope away from the tops of slopes and all slopes have been covered with jute matting and 6ydroseeded for erosion protection. In our opinion, where slopes 6ave been placed, compacted, graded, and vegetated as described above, the minimum building setback distance can be reduced to ]0 feet. The setback distance is the horizontal distance measured from the front face of the footing to the face of the slope. It s6ould be understood that if the setback distance is reduced to 10 feet, the risks of losing access, reducing the d�ign life of the foundatioiu and having slope novement impact the house foundations are increased. ,. :,��:��... . , �, „�, F.�,c:��,,ud.�Ca ,�.� :_ i�..a^:iom��:",,. � � hA��'�Nu�bl�o��c .��;e:a-.,HY.e e-':�:� .
