1 <br /> 1 <br /> ' APPENDIX A <br /> FIELD EXPLORATION <br /> ' Seaway Center Lot 3C <br /> Everett,Washington <br /> ' We performed our field work at the site on May 17, 2006 and September 7, 2007, Our subsurface explorations <br /> included excavating 10 test pits to maximum depths of about 8 to 14 feet below existing surface grades using a <br /> track-mounted excavator. We determined the approximate locations of our site explorations by measuring <br /> 1 relative to existing surface features. The approximate locations of the test pits are shown on Figure 2. The Test <br /> Pit Logs are presented in Appendix A. <br /> An engineering geologist from our office conducted the field explorations, maintained a Iog of each test pit, <br /> collected representative soil samples, and performed a visual reconnaissance of the site. All soil samples <br /> collected from the site explorations were visually classified in accordance with the Unified Soil Classification <br /> System(USCS)described on Figure A-I. <br /> Representative soil samples collected from the lest pits were placed in closed containers and taken to our <br /> ' laboratory for further examination and testing. The moisture content of each sample was measured and is <br /> reported on the Test Pit Logs. Grain size analyses were performed on six samples. The results are shown on <br /> ' Figures A-9 through A-I 1. Atterberg Limits were determined for one soil sample. The test results are shown on <br /> the appropriate Test Pit Log. <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> i <br /> 1 <br /> 1 <br /> Project No. T-5922-1 <br /> 1 <br />
