J eig Rock Road <br />Duvall, Washington 98019 <br />Attention: Silver Iake Short Plat <br />Silver Lake Road <br />Everett, Washington <br />Dear Mr. Gustavson: <br />At your request, we have conducted a subsurface soil investiga- <br />tion at the above site. The following report summarizes our field <br />observations and presents our conclusionu and recommendations. <br />Based on our conversation with ycu and our review of the Record of <br />Survey & Short Plat Map by Western Surveyors, Inc. dated October, <br />1988, we understand that the project will consist of a seven (7) <br />lot short plat with a twenty (20) foot wide paved access roadway <br />and cul de sac. We understand that the roadway will be a private <br />road, approximately twenty (20) feet wide. <br />SCOPE <br />The scope of our investigation was to observe the cu•�aurface soil <br />conditions in the area of the proposed roadway, and to previde <br />recommendations regarding roadway construction. The test pit sites <br />were determined by our engineerinq geologiat and were located by <br />measuring from known landmarks. The soils observed in the test <br />pits were described in the field and classified using the Unified <br />Soils Classification System.._ The test pit locations may be seen on <br />the Test Pit Location Map in ANpendix A. The Test Pit Logs and <br />detailed soil descriptions are presented in Appendix B. <br />
