We h�ve observad no signs of iastability on native alopes in Divisions III u�d N.

'ILe shvcdual fi11 is keyed inw existing fum native aoiis uid fill placed to achieve the final slope grades haa bcea properly benched into ezisting native materials and compacted w 95 perceat of 1vIDD (maximum dry densiry)according to the apecifications of the ASTM D-1557 test procedure, ln addition,the lots are graded to slope away from the tops of slopes and all slopes have been covaed with jute matting and hydroseeded for erosion protection. In our opiuion, whae slopes have ban plac�d, compaaed, graded, and vegetated as described above, the minimum building saback distance can be reduced to 10 fea. The saback distaace is the horizontal distance measured from the front face of the footing eo ttie 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 and having slope movement impact the house foundationc are increated. .,..., .,,. e. . • - , �:,<<_ :.:�,y.. .i.;... . ,_:��<:.:.::,:, .
