APPENDIX A FIELD EXPLORATION E-3592-520 Our subsurface exploration was performed on August 31, 1998. Subsurface conditions at the site were explored by excavating four test pits to a maximum depth of sixteen (16) feet below existing grade. The test pits were excavated by Northwest Excavating subcontracted to ECI, using a trackhoe. Appraximate test pit locations were determined by pacing from features depicted on the site plan provided by the client. The approximate test pit elevations were estimated relative to each other. The locations and elevations of the test pits should be considered accurate only to the degree implied by the method used. These approximate locations are shown on the Test Pit Location Plan, Plate 2. The field exploration was continuously monitored by a staff geologist from our firm who classified the soils encountered, maintained a log of each test pit, obtained representative samples, and observed pertinent site features. All samples were visually classified in accordance with the Unified Soil Classification System which is presented on Plate A1, Legend. Representative soil samples were placed in closed containers and returned to our laboratory for further examination and testing. Logs of the test pits are presented on Plates A2 through A5. The final logs represent our interpretations of the field logs and the results of the laboratory examination and tests of field samples. The stratification lines on the logs represent the approximate boundaries between soil types. In actuality, the transitions may be more gradual. Earth Coneultente, Inc.
