� �, 2. �ITE DESCRIPTICN The site is located on the sauth side of Silver Lake Road between 15th Drive S.E. and 19th Avenue S.E., (SR-527) in Snohomish County, Washington. The property is bounded on the south by an undeveloped woaded lot. Residential homes presently occupy the properties on the eastern and western sides of the site. The site is flat and appears to have been filled in the recent past with on the order of five to six feet of silty sand and gravel. The surface of the site was apparently quit�+ marshy and poorly drained before filling. A small creek which provides an outlet for Silver Lake, drains through a broad swale on the east side of the site after it crosses br:neath Silver Lake Road in a i culvert. 3. FIELD EXPLORATION The subsurface conditions were explored at the site on October 14, 1981 by excavating a series of nine test pits to a mar.imum depth of 12.5 feet. The approximate locations of the test pits are oresented on the Site Plan, Figure 2. Logs of the test pits are presen�ed in the Appendix to this report. The test plts were located in the field by pacing from existing site features. Test pit elevations were interpolated from the contours shown on the site plan provide� to us by The Axelrod Company. The locations and elevations should only be considered approximate. The test pits were excavated with a rubber tired backhoe under subcontract to a local excavating contractor. Disturbed but representative uulk samples of the so'•ls encountered in the test pits were retrieved. The representative soil samples were classified in accordance with the Unified Soil Classification System. The test pits were excavated under the direction of a staff engineer from our firm, who examined and classified the soils encountered, obtained representative samples, and recorded the pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and groundwater occurrence. All samples were sealed to prevent moisture loss and returned to our laboratory for further examination. The depths listed for boundaries between soil types are approximate; actual transitions may be eithe�� more gradual or more severe. The soil and groundwater conditions are those recorded for the dates indicated and may not necessarily represent those of other times or locations. Golder Assoclates
