Thomas i(elly JN 95192 <br /> June 7, 1995 <br /> Page 2 <br /> based upon !'r�e proposed constructfon and required design criteria, the s�te topography and <br /> access, the subsurface conditions revealed during excavation, the scope of work outlined in <br /> our proposal, and the time and budget constraints. <br /> Tha test pits were excavated on May 30, 1995 with a rubber-tired backhoe. A geotechnical <br /> engineer from our staff observed the excavation process, logged the test pits, and obtained <br /> representative samples of the soils encountered. "Grab" samples of selected subsurface <br /> soils were collected from the backhoe bucket. The Test Pit Logs are attached to this report <br /> as Plate 3. <br /> Both test pits encountered relatfvely clean sands. These sands were fine- to <br /> madium-grained and loose near the ground surface, becoming medium•dense at a depth of <br /> 6 to 7 feet below the ground suriace. The near-surface sands contained organics and woo� <br /> fragments. This topsoil layer varied from 1 to 3 feet in depth at the locations explored, <br /> The finai logs represent our interpretations of the field logs and laboratory tesis. The logs <br /> provide specific subsurtace informatfon only at the locations tested. The relative densities <br /> and moisture descriptions indicated on the test pit logs are interpretive descriptions based <br /> on the conditions observed during excavation. <br /> The cornpaction of backfill was not in the scope of our services. Loose soils will therefore <br /> be tound in ihe area of the test pits. If this presents a problem, the backfill will need to be <br /> removed and replaced with structural fili during construction. <br /> G�Qs�ndv�tateL <br /> No groundwater seepage was observed in the test pits. It should be noted that groundwater <br /> levels vary seasonelly with rainfall and other factors. However, due to the permeable nature <br /> of the soil: .ve anticipate that groundwater will not be found during construction. <br /> CONCLUSIQL`L�AND}3ECOMMEND1gILQLIS_ <br /> �@IIS'f�l � <br /> The site has been classified by the City of Everett as em�ironmentally sensitive due to the <br /> slope south and west of the proposed house site. The city requires a buHar of 25 feet from <br /> the top, toe, and sides of steeper slopes. However, a provision in the city's ordinance <br /> allows 1or the moditication oi the bufter zone. The modification should not adversely affect <br /> the stability of the slope.
