CASCADE GEOTECHNICAL March 27, 1991 The December Partnership Job No. 9102-18G Page 3 central part adjacent to the property. The site is bounded on the south by relatively flat ground. At the time of cur visit, the on-eite soils at the surfacc wrre wet and very soft. The site was moatly vegetated with qrass and some blackberry bushes. Some cottonwood, and wild cherry trees were observed scatteried along the property boundaries. We understanu from our conversations with neighburs that the previous owner had placed fill in a lowland with standinq water some years aqo. SUBBURFACE CONDITIONB The aite sub�urface conditions were investigated by excavatir.g flve (5) backhoe test �.its on February 21, 1991, and by drillinq two (2) twenty-four (24) foot test borinqs on March 7, 1991. The teat borings were performed using a hollow stem auger and standard split spoon sampling in accordance with ASTM D-1586 sampling procedures. The test boring and test pit locations were chosen in the field by our qeologist. Test boring and test pit locations were determined by pacinq relative to property lines and from known landmarks on- site. The test pit and test boring location map is presented in Appendix A. The test pit logs and detailed soils descriptions are presented in Appendix B. The test boring loqs and detailed soil descriptions are presented in Appendix C. The soils observed in the test pits and test borinqs were described in the field and classified using the Unified Soils Claasification Sy�tem. A copy of this classification system is presented in Appendix D. All elevations mentioned in this report are referenced to the existinq grade at the time of our fieldwork.
