APPENDIX A FIELD EXPLORATION AND LABORATORY TESTING Baywood Industrial Everett,Washington On September 9,2019,we explored subsurface conditions at the site by performing 5 cone penetration tests(CPTs) at the site. The CPT locations were approximately determined in the field using by sighting and using GPS coordinates. The CPT locations are shown on Figure 2. In Situ Engineering, Inc., under subcontract to Terra Associates, Inc. performed the CPTs at locations selected by Terra Associates, Inc. The maximum depth the CPTs were advanced was 80 feet below the surface. The CPT consists of pushing an instrumented, approximately 1 1/2-inch diameter cone into the ground at a constant rate. During advancement,continuous measurements are made of the resistance to penetration of the cone and the friction of the outer surface of a sleeve. The cone is also equipped with a porous filter and a pressure transducer for measuring groundwater or pore water pressure generated. Pore pressure dissipation tests were completed at four of the CPT locations to determine groundwater depths. Measurements of tip and sleeve frictional resistance, pore pressure, and interpreted soil conditions and groundwater depths are summarized in graphical form on the CPT Logs attached in Appendix A. Project No. T-8221
