GeomImnmenral and Gmlogic Services Building Setback Conditions Hanabrook Development Divisions III and IV Everett, Washington File No. 2670-005-1106 The purpose of this letter is to cudine reduced building setback conditions for location of homes at the tops of sloi.es on Divisions III and IV of the Hanabrook Development in Everett, Washington. This has bo-.n discussed with Mr. Randy Clark of Select Homes, Mr. Fat McCourt of Universal Brokerage Corporat'.on, aad Mr. Michael Crowson of W&H Pacific. We have observe I : - sign; of i.istability on native slopes in Divisions III and IV. Fill slopes on Divisions III a:d IV were : jmtructed with structural fill consisting of on -site granular soils under full-time mouitorim, - if a qualified individual from our firm. The structural fill is keyed into existing rim natb a soils and fill placed to achieve the final slope grades has been properly hinched into existing native materials and compacted to 95 percent of MDD (maximum dry density) according to the specifications of the ASTM D-1557 test procedure. In 216uition, the lots are graded to slope away from the tops of slopes and all slopes have been covered with jute malting at.d hydroseetel for erosion 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 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 are increased. rkeEnglnm Inc. 8,110 151th Mime N.E.
