This has been discussed with Mt• RandY Clazk of Select Hoces, Mr. Pat McCourt of Universal Brolcera8e Cocporation, and Mr. Michaei Crowson of W&H Pacific. We have obsmed no signs of instability on native slopes in Div;�io�s III and IV.

'Ibe stcuctural fill is keyed into existing firm native soils and fill placed to achieve the final slope grades hu heen properly benched into existing native macer�als ar�d compacted to 95 percent of MDD (maximum dry density)according to the specificarions of the ASTM D-1557 test procedure. In addition,the lou are graded to slope away ftom the tops of slopes and all slopes have been covered with jute matting and 6ydroseeded for erosion protection. raded, and ve etated as In our opinion, where slopes have bezn placed, compacted, g B described above, tfie minimum building setback distance can be reduced to 10 feet. The setback distance is the horizontal distance measured from the front face of the footing to the face of the slope. It should be understood that if die 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.
