Select Homes 237 Elm Strat Everett, Washington 98203 Aaention: Mr. Randy Clazk Building Setback Conditions Hanabrook Development Divisions IIi and N Everett, Washington File No. 2670-005-R06 7t�e pu�pose of this letta is to ontline reduced building setback conditions for locadon of homes at H�e tops of slopes on Divisioas III and N of the Hanabrook Development in Everett, Waahington. This has been discussed with Mr• Randy Clazk of Select Homes, Mr. Pat McCourt of Universal Brotasge Co[poration, and Mr. Michael Crowson of W&H Pacific. We have observed no siges of instability on native slopes in Divisions IQ end N. Fill slopes on Divisions III and IV wao cons�M�"��S��ral fill consisting of on-site granulaz soils unda full-time monitoring of a qualified individual from our firm. The swctu�al fi11 is keyed into e�cisting firm native soils and fill placed to achieve the final slope grades has been properly benched into ezisting native materials and compacted to 95 percent of MDD (maximum dry density)according to the specifications of the ASTM D-1557 test procedure. In addition,the lou aze graded to slope away from the tops of slopes and all slopes have been covered with jute matting and 6ydroseeded for ero�'�n protection. In our opinion, where slopes have been placed, compacted, graded, and vegetated as described above,the 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 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.
