� <br /> . APPENDIX A <br /> FIELD EXPLORATION <br /> � Fr4888 <br /> . Our 6eld exPloration was performed on April 24, 1990. Subsurface co�ditions at the site <br /> were explored hy txcavating n•ne test pits to a maximum depth of ten feet below existing <br /> grade. <br /> � Approximate test pit locations were determined by taping from the curb line of Casino Road <br /> and the fence to the east. Approximate test pit elevatio,u were determined by interpclation <br /> � from the topographic map pror.ded by Toid Development. The locations and elevations of <br /> the test piu should be rnnsidered accurate aily to the degree implied by the method used. <br /> These appro�cimate locations are shown on the Test Pit Location Plan, Plate 2. <br /> � The field exploration was continuously monitored by an engineering geologist from our firm <br /> who classified the soils encountered and maintained a log of each test pit, obtained <br /> representative samples, measured groundwater levels, and obser ed pertinent site features. <br /> � All samples were visually classi6ed in accordance with the Unified Soil Classiflication System <br /> which is presented on Plate Al, Legend. Test Pit L.ogs are presented on Plates A2 through <br /> A6. The final logs represent our interpretations of the field logs and the resulu of the <br /> � laboratory examination and tests of field samples. The stratifcation lines on the logs <br /> represent the approximate boundaries between soil types. In actuaiiry, the transitions may <br /> be more gradual. <br /> � The consistency of the soil waz estimated based on the effort required to excavate the soil, <br /> the stabiliry of the trench walls, and other factors. <br /> � Representative soil samples were placed in closed containers and retumed to our laboiatory <br /> for further examination and testing. <br /> � <br /> � <br /> , <br /> , <br /> � <br /> � <br /> � <br /> � <br /> , Eerth Consultants, Inc. <br />
