Gmenrlronmuital and Geologic Sere Ices Building Setback Conditions Hanabrook Development Divisions III and IV Everett, Washington File No. 2670-005-1106 The purpose of this letter is to outline reduced building setback conditions for location of homes at the tops of slopes on Divisions III and IV of die Hanabrook Development in Everett, Washington. This has been discussed with Mr. Randy Clark of Select Homes, Mr. Pat McCourt of Universal Brokerage Corporation, and Mr. Michael Crowson of W&H Pacific. We have observed no signs of instability on native slopes in Divisions III and IV. Fill slopes on Divisions III and IV were constructed with structural fill consisting of on -site granular soils under full-time monitoring of a qualified individual from our firm. The structural fill is keyed into existing firm native soils and fill placed to achieve the final slope grades has been properly benched into existing native materials and compacted to 95 percent of MDP (maximum dry density) according to the specifications of the ASTM D-1557 test procedure. :. _ddition, the lots are graded to slope away from the tops of slopes and all slopes have been covered with juts matting and hydrosooded for erosion protection. In our opinion, where slopes have bcen placed, compacted, graded, and vegetated as described above, the minimum building setback distance can be reduced to 10 feet. 'Die setback distance is the horizontal distance measured from the front face of die footing to the 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 foundations tre increased.
