Investigation <br /> The field investigation included drilling and sampling eight exploratory borings at the <br /> approximate locations presented on Figure 1 as selected by the client. The borings were drilled <br /> to depths of approximately 15 to 25 feet using 4-inch diameter continuous-flight augers, and a <br /> truck-mounted drill rig. Drilling was observed by our field representative who logged the soils and <br /> bedrock and obtained samples for laboratory tests. Summary logs of the exploratory borings, <br /> including results of field penetration resistance tests and a portion of laboratory test data, are <br /> presented on Figure 2. <br /> Soil and bedrock samples obtained during drilling were returned to our laboratory and <br /> visually examined by our geotechnical engineer. Laboratory testing was assigned by the client <br /> and included moisture content, dry density, particle-size analysis, direct shear, and Atterberg <br /> limits. Results of the laboratory tests are presented in Appendix A and summarized in Table A-I. <br /> Subsurface Conditions <br /> Strata encountered in our exploratory borings generally consisted of 8 to 23 feet of clayey <br /> sands and sandy clays. Sandstone and claystone bedrock was encountered in all borings at 8 to <br /> 24 feet to the maximum depths explored. The sand encountered was loose to very dense and <br /> contained between 6 and 46 percent silt and clay sized particles. <br /> Groundwater <br /> Groundwater was encountered at a depth of 24 feet in one boring during drilling. <br /> Groundwater may develop on or near the bedrock surface or other low permeable soil or bedrock <br /> when a source of water not presently contributing becomes available. <br /> Limitations <br /> This report has been prepared for the exclusive use of TRC Companies, and the design <br /> team for the project, to provide geotechnical information for the proposed project. within about <br /> three years, we should be contacted to determine if we should update this report. Our borings <br /> and laboratory testing were determined by the client. The borings are representative of conditions <br /> encountered only at the location drilled.
