Allestad June 18 , 1990 SCOPE OF WORK our geotechnical evaluation included subsurface exploration, enqineering evaluations, and the preparation of this report. The scope of work included the following specific tasks: o Excavated five test pits to depths ranging from 6.5 to 12 feet below the ground surface to obser e the subsurface soiJ. conditions. Approximate locations of the tesc pits are shown on Figure 2. o Continuously logged the subsurface conditions, as encountered in the test pits at the time of excavation. Logs of the test pits are presented on the summary sheets of Appendix A. o Performed engineering evaluations of the site conditions and developed appropriate recom- mendations for foundations systems, temporary excavations, retaining walls and site gradinq. o Prepared this geotechnical report summarizing our findings and recommendations for site development. EXISTING SZTE CONDITIONS The proposed residence site is located ir, a small swale area at the extreme southerly end of the Pigeon Creek canyon in Everett, Washington (see Figure 1) . The site is bordered by residential property on the east and south, �y an Everett sewage pump station on the west and by Magnolia Avenue on the north. At the time of our field investiqation, the site had been previously cleared but was undeveloped. Vegetation on the site consisted primarily of heavy blackberry growth on all but the east slope which was covered with grasses and brush. The heavy blackberry growth had recently been cut down but cuttings remained on the site. Some large (18 to 24 inch diameter) tree stumps were observed in the east central area of the site. Topoqraphy in the site vicinity is generally rather flat lying except for the small swale in which the site lies as shawn in Figure 1. Local site topography is approximately depicted on Figure 2. The existing site topography consists of a relatively flat lying area in the southwest quadrant of �he site which slopes up gently to Magnolia Avenue at the north end of the lot. At the north-central area of the site a low area exists which appears to have been created by fill placement from the consturction of Magnolia Avenue and other sources. On the east side a short but steep slopa exists along the full lengtY. of the east property boundary. The east slope drops down steeply from the adjoining lot to the east with slope angles measured in the ranqe of 20 to 40 Page No. 2 Project No. 90-122-01
