APPENDIX A FIELD EXPLORATION AND LABORATORY TESTING Proposed Storage Building Everett,Washington On August 21, 2007, we completed our site exploration by observing soil conditions at 5 test pits. The test pits were excavated using a track-mounted excavator to a maximum depth of 15 feet below existing site grades. Test pit locations were determined in the field by measurements from existing site features. The approximate location of the test pits is shown on the attached Exploration Location Plan, Figure 2. Test Pit Logs are attached as Figures A-2 through A-6. A geotechnical engineer from our office conducted the field exploration. Our representative classified the soil conditions encountered, maintained a log of each test pit, obtained representative soil samples,and recorded water levels observed during excavation. All soil samples were visually classified in accordance with the Unified Soil Classification System(USCS)described on Figure A-I. Representative soil samples obtained from the test pits were placed in closed containers and taken to our laboratory for further examination and testing. The moisture content of each sample was measured and is morted on the individual Test Pit Logs. Grain size analyses were performed on selected samples. The results of grain size analyses are shown on Figure A-7. Project No. T-6116-2
