Box 21688 <br />Seattle, Washington 98111 <br />Subject: Geotechnical Engineering Study <br />Proposed Rucker Village Condominiums <br />Grand Avenue at 38th Street <br />Everett, Washington <br />Dear Mr. Pirie: <br />March 19, 1997 <br />JN 97072 <br />GC7 12 1998 <br />............................................................... _.. <br />CITY OF EVERETT <br />Permit Services <br />We are pleased to present this geotechnical engineering report for the condominium complex to be <br />constructed in Everett, Washington. The scope of our work consisted of exploring site surface and <br />subsurface conditions, and then developing this report to provide recommendations for general <br />earthwork and design criteria for foundations, retaining walls, and pavements. You authorized our <br />work by accepting our proposal, P-4042, dated October 24, 1997. <br />The subsurface conditions of the proposed Village site were explored with seven test pits that <br />encountered one to 2 feet of topsoil and loose fill overlying native, gravelly, silty sands. The native <br />sands became medium -dense to dense below a depth of one to 3 feet in the explorations. Due to <br />the potential for noticeable differential foundation settlement to occur at this site, conventional <br />footings used to support the buildings should all bear on competent, undisturbed, native soils or on <br />no more than 5 feet of structural fill. This will require extending columns and walls, then filling <br />under the slab areas. The extensive cutting and filling necessary to grade the site will only be <br />possible during dry weather. The silty, moisture -sensitive soils will not be compactible for structural <br />fill in wet conditions. <br />The attached report contains a discussion of the study and our recommendations. Please contact <br />us, if there are any questions regarding this report or if we can be of further assistance during the <br />design and construction phases of this project. <br />Respectfully submitted, <br />GEOTECH CONSULTANTS, INC. <br />Marc R.
