Box 2947 <br /> Mount Vernon,Washington 98273 <br /> Subject: Geotechnical Engineering Study <br /> Proposed Tank Foundation <br /> 1407-80th Street Southwest <br /> Everett,WA <br /> Dear Mr.Axthelm: via email: <br /> This report presents the findings and recommendations of our geotechnical engineering study for the proposed <br /> tank foundation to be constructed at the Achilles Plant at 1407 - 80th Street Southwest in Everett. The <br /> undersigned associate visited the subject site on September 16,2016. The purpose of this visit was to observe <br /> the existing site conditions,observe test pits dug by the client,and to develop opinions regarding the soil bearing <br /> for new tank foundation. The recommendations and conclusions presented in this report are professional <br /> opinions based on the visual observations made during our site visit and on previous experience with similar <br /> projects. We excavated shallow test pits during our visit, but no deep subsurface explorations were conducted <br /> for our work. <br /> We were not provided with any plans for the proposed addition, but we understand through discussions with <br /> you at the site that a new tank(silo)foundation will be constructed in the area of the test pits. The foundation <br /> will be shallow(on the order of 2 to 3 feet thick). <br /> If the scope of the project changes from what we have described above, we should be provided with revised <br /> plans in order to determine if modifications to the recommendations and conclusions of this report are <br /> warranted. <br /> SITE CONDITIONS <br /> The generally site rectangular-shaped subject site slopes gently to moderately to the north off of the street front. <br /> The site of the tanks is vegetated with grass and is amongst the central portion of the plant. Existing shallowly <br /> founded structures are around the tank area. No evidence of large scale-settlement was observed in the <br /> foundation. <br /> Our understanding of the subsurface conditions at the site is based on the observations made during our recent <br /> site visit and on experience gained from other projects in the site vicinity. During our visits,we excavated two <br /> shallow test pits with a small trackhoe at the southern and northern portions of the proposed addition. (as <br /> depicted below): <br />
