Select Homes 237 Elm Sueet Everett, Wazhington 98203 Auendon: Mr. Randy Clark Building Setback Conditions Haoabrook Development Divisions III aad IV Everett, Washington File No. 2670-005-R06 'Ihe purpose of t6is letta is to outline reduced building setback conditions for locadon of homes at the Wps of slopes on Divisioas III and N of the Hanabrook Development in Everett, Washington. This 6u been disea�ssed with Mr. Randy Clazk of Select Homes, Mr.Pat McCourt � of Univaaal Brokerage Co�poration, and Mr. Michael Crowson of WdcEI Pacific. We have obsaved eo sigos of instability on native siopes in Divisions III and N. Fill sle�pes on Divisions III and IV wae conswcted with swcturat fiIl consisting of on-site granular soils under full-time moniwring of a qualifiad individual fmm our fum. 'Ibe stiuctural 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 MDD (maximum dry density)acco�ding to the specifications of the ASTM D-1557 test procedure. In addition,the lots are graded t: slope away from the tops of slopes and all slopes have been covered w�ith jute matting and 6ydroseeded fur erosion ptotection. In our opinion, w6ere 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 measurad froiv ihe front face of the 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 tbundations and having slope movement impact the house foundations are increased. ;�t,,,,. � �� . .
