'!be purpose of this leuer is to outline reduced building setback c.�cditionti for location of homes at tha tops of slopes on Divisioas III and I'' of the Hana6rook �evelopment in Everea, Wu6ington. 1Tiis has been discussed with Mr. Randy Ciazk of Select Hom�, Mr. Pat McCo�ut of Univert,ai Brolcuage Corporation, and Mr. Michad Crowson of W&H Pacific. We 6c �e obsaved no sigat of instability on native slopes in Divisions III and N. Fill slopea on Divisions III anti N wae coatuvcted with swctural fill coasisting of on-site granulaz soils undrr tull-time meni:orirt of a qualified individual from our firm. 'Ihe stcuctural fill is keyad inu� e�i-dng firm nadve soils and fill placed to achieve the final slope grades has becn properly benchai into existing native materials and compacted to 95 peccent of MDD (maximum dry density) accordinq W the specificadons of the ASTM D-1557 test procedure. In addition, the lots are gra�ied ro slope away from the tops of slopes and all stopes have been wvered with jute matting and 6ydroseeded for erosion protection. In our opinion, where siopes have been placed, compacted, graded, and vegetated as described above, the minimum building setback distance can be reduced to 10 feet. The setback distauce is the borizontal distance measured from the tront fa:e of the footing to the face of the siope. It shouid be understood that if ihe 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 heuse foundationc are increued. i.r�:r�<<�� In� I�' I�!'!� 1',�I'�urA � .,�:ri�� n.LAAS1 0>��;_ ,ucpl��.,;,�i:..�•Y,;� ��,.� i.i� � `u,� ..,; ��i9n
