Geotechnical Engineering Report Parcel 00471700002401- 57XX East Drive Everett, Washington December 12, 2009 RMI File No. 53409 Page 2 EXISTING CONDITIONS General We reviewed the general geologic information on the site, which is shown on the Geologic Map of Surficial Deposits in the Seattle 30' by 60' Quadrangle, Washington by James C. Yount et al, (1993 — USGS Open File Report 93-233). The site area, slope profile and observed conditions are shown on the enclosed Site Plan (Figure 2) or Schematic Cross -Section A -A' (Figure 3). Surface Conditions The site is on East Drive in Everett and runs east -west (Figure 1: Vicinity Map). There is a small ravine near its western end. Most of the lot is flat beginning at its access to East Drive. It has been cleared up to about 30 feet from the ravine in its rear. The area near the ravine slopes towards it by about 3 degrees. The ravine slopes down at about 29 degrees (55 percent) and is between 20 and 25 feet deep. The slopes are covered with tall coniferous trees, vegetation and shrubs. Within the 30 feet nearest the ravine there are tall coniferous trees. The soil in this area has been mapped as Vashon till (Qvt) but exposures in the cleared section indicate that it is an advance outwash deposit (Qva) of sands and gravels. There are no significant geologic contacts, landslides or downslope soil movement on within 200 yards. There are no utilities, structures, roads, etc, on the property. There are no existing fill areas. The Cross -Section was constructed from measurements taken onsite with a digital level and tape. Geologic Conditions Landforms within this region comprise a system of glacially sculptured features, which have been exposed by post -glacial erosion. Locally, the terrain of this area has been glacially modified. The soils were placed either prior to, or during the latest glaciation of the Puget Lowland area. Glacial ice last occupied the region during the late Pleistocene epoch, some 10,000 to 13,000 years before the present. RMI ASSOCIATES LLC 3 /
