� � � �i ] II� � CJ � � � � � � � � � � � � APPENDIX A FIELD EXPLORATION E-11880 Our field exploration was performed on July 6, 2005. Subsurface conditions at the site were explored by excavating 6 test pits to a maximum exploration depth of 14.5 feet below existing grade. The test pits were excavated by Northwest Excavating, subcontracted to Earth Consultants, Inc. (ECq, using a rubber-tired backhoe. Approximate test pit locations were estimated by pacing from site features depicted on the site plan provided by the client. The test pit elevations were based on the topographic data shown on a preliminary site plan provided by the project architect. The locations and elevations should be considered accurate only to the degree implied by the method used. These approximate locations are shown on the Test Pit Lccation Plan, Plate 2. The field exploration was continuou��y monitored by a 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 that is presented on Plate A1, Legend. Logs of the test pits are presented on Plates A2 through A7. The final logs represent our interpretations of the field logs and the results of the laboratory tests on field samples. The stratification lines on the loqs represent the approximate boundaries between soil types. In actuality, the transitions may be more gradual. Representative soil samples were collected and returned to our laboratory for further examination and testing. Earth Consuliams, Inc
