APPENDIX A FIELD EXPLORATION E-10558 ECI's field exploration was performed on April 17, 2003. Subsurface conditions at the site were explored by excavating six test pits to a maximum depth of fourteen (14) feet below the existing grade. The test pits were excavated by Northwest Excavating subcontracted to ECI, using a trackhoe. Approximate test pit locations were determined by pacing from site features. Approximate test pit elevations were determined by locating on the site plan. 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 geologist from our firm who classified the soils encountered, maintained a log of each test pit, obtained representative samples, measured groundwater levels, and observed pertinent site features. 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. Test Pit Logs are presented on Plates A2 through A7. The final logs represent our interpretations of the field logs and the results of the laboratory 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. The consistency of the soil shown on the logs was estimated based on the effort required to excavate the soil, the stability of the trench walls, and other factors. Earth Consultants, Inc.
