Randy Clazk <br /> Building Setback Conditions <br /> Hanabrook Development <br /> Divisions III and IV <br /> Everett, Washington <br /> File No. 2670-005-R06 <br /> The pumose of this letter is W oudine reduced building setback wnditions for location of <br /> homes at the tops of::lopes on Divisions III and IV of the FIanabrook Development in Everett, <br /> Wathington. This has been discussed with Mr. Randy Clazr of Select Homes, Mr. Pat McCourt <br /> of Universal Brokerage C.orporation, and Mr. M�chael Crowson of W&H Pacific. <br /> We have observed no signs af instability �u native slopes in Divisions III and IV. Fill <br /> slopes on Divisions III and IV ever�s coaswcted with sauctural fill wusisting of on-site granulaz <br /> soiis under ful►time monitoriag of a qualifiod individual from our firm. 'ILe swctural fill is <br /> Iceyed inw existing firm native soils and fill placed to achieve the final slope grades has been <br /> properly benched into existing native materials and compacted to 95 percent of MDD (maximum <br /> dry deneiry)according to the specifications of the ASTM D-1557 test procedure. In addition,the <br /> lots aze graded tu slope away from ;he tops of slopes and all slopes have been covered with jute <br /> mattiog and hydro�eaued for erosion protection. <br /> In our opinion, where slopes have been placed, compacted, graded, and vegetated as <br /> described above, the minimum h ailding s�bxck distance can be re�uced to 10 feet. The setback <br /> distance is the horizontal distance me;sured from the front face of the footing to the face of the <br /> slope. It should be understood that if the setback distance is reduced to l0 feet, the risks oC <br /> losing access, reducing the design life of the foundations and having slope movement impact the <br /> house foundations are increased.
