Uuc to sensilivc steep slopes within the northern lot, wc <br />recommend that grading and found:ition construction work for the proposed ncw residence be <br />carried out and completcd in thc dryer period from April 1 to Octobcr 31. The slope <br />s►abilizution, erosion mitigation and druinage control mcusures recommended in this rcport <br />shuuld bc in placc and operstional during construction as well as outsidc of this drycr period to <br />maintnin sitc st�biliry. <br />�'he tnpsoil should M: stripped wiiliin the building pad ol'�he proposed neH- rcsidence. Thc luos.� <br />fill encountered by "1'est lluring [3-1 in tl�c footprint of tlic west gnroge should bc removcd as <br />much as praclicahlc within Uic building pads. 7'he over-excavntion should be backlilled with <br />structural filL Com•entionnl footing foundations pourcd on or into dense fispernnce Sand or hazd <br />Whidbcy fonnation soils. Whcrc loose fill within thc building pud cannot be completely <br />rcmo��cd economically, pilc fo�ndations should be used to penc:rate the loose fill and seated into <br />thc underlying dcnsc Gsperance Sand or hard 1Vhidtxy formation deposits to suppori the <br />huilding. <br />L[U & ASSOCIATES,INC. <br />
