r <br /> 51xx Ocean Avenue (Parcel#00571700100100) January 8, 2018 <br /> Everett, Washington Project#17110 <br /> Bustard Custom Construction, Inc. <br /> PO Box 1243 <br /> Marysville, WA 98270 <br /> Attention: Paul Bustard <br /> Subject: Geotechnical Plan Review <br /> 51xx Ocean Avenue (Parcel #00571700100100) , <br /> Everett, Washington <br /> Mr. Bustard: <br /> The purpose of this letter is to review the civil engineering and structural engineering plans for <br /> the proposed construction with respect to the geotechnical aspects of the subject property. <br /> Electronic copies of the plans were provided to us via e-mail for our review.The individual plan <br /> sheets reviewed are referenced at the end of this letter. <br /> In general, we found the reviewed plans to be in accordance with the recommendations made <br /> in our referenced geotechnical report (SFG, November 1, 2017). However,the structural plans <br /> reviewed do not have fixed elevations shown for the floors and other features of the home. <br /> Our geotechnical report identified fill soils that are not adequate for structural support in their <br /> present state. Based on our discussions, it is understanding that you intend to over-excavate <br /> the existing fill soil and set the planned foundation directly on native bearing soils or on a <br /> documented structural fill set to bear on dense native sediments. In consideration of the <br /> location of the building pad, the existing topography, and the over-excavation that will be <br /> required to mitigate the existing fill soils,there are several elements of the building <br /> construction that will need to be verified by the geotechnical engineer(GE) and the structural <br /> engineer(SE) in the field as construction progresses. These elements are listed below: <br /> • Verification of bearing soils (GE) <br /> • Verification of foundation steps and temporary cut slopes (GE &SE) <br /> • Documentation of potential structural fill material (GE) <br /> • Retaining wall design/sizing based on actual wall and retained soil height, to be <br /> determined after bearing soils have been reached (SE) <br /> • Foundation drainage installation (GE) <br /> These elements are vital to the design and long-term performance of the proposed structure. '- <br /> The <br /> The geotechnical engineer and structural engineer should be retained to perform these <br /> construction monitoring services during construction. <br /> r\\ <br /> JAN 1 1 2018 1 <br /> 5, 1 <br /> C[IY OF EVERETT <br /> Permit Services <br /> SOUTH FORK GEOSCIENCES, PLLC Page y./_.) <br /> PO Box 1275 + <br /> NORTH BEND,WA 98045 a <br /> 425-831-2023 I ANDREW@SFGEO.COM <br />
