Kraus-Anderson Realty Company <br /> Project BL-11-01014 <br /> March 18,2011 <br /> Page 3 <br /> The samples obtained during our field explorations were returned to our office where they were visually <br /> classified in general accordance with the Unified Soil Classification System (USCS) by a member of our <br /> engineering staff. Representative samples obtained were then selected for laboratory testing. Laboratory <br /> tests were conducted in general accordance with applicable ASTM Standards.The results of laboratory <br /> tests are discussed in the following sections of this report and are shown on the boring logs in the <br /> Appendix. <br /> B. Results <br /> B.1. Boring Logs <br /> B.1.a. General <br /> Boring Logs for each of our borings are included in the Appendix.The logs identify and describe the <br /> geologic materials that were penetrated,the results of SPT and laboratory tests performed on samples <br /> retrieved obtained and our groundwater observations at the time of drilling. <br /> Strata boundaries were inferred from changes in the penetration test samples and the drill auger <br /> cuttings. Because sampling was not performed continuously,the strata boundary depths are only <br /> approximate.The boundary depths likely vary away from the boring locations, and the boundaries <br /> themselves may also occur as gradual rather than abrupt transitions. <br /> B.1.b. Previous Soil Borings <br /> We used the information obtained from previous borings performed on site in our analyses and to <br /> formulate our recommendations for the proposed development.Since it is possible site grading or filling <br /> has occurred since the previous explorations,the following summary of soils only includes the current <br /> soil borings drilled during this evaluation. However,the previous boring logs are provided in the <br /> Appendix of this report.The soils encountered by our current soil borings are generally consistent with <br /> soil conditions encountered in our previous soil borings. <br /> B.1.c. Geologic Origins <br /> Geologic origins assigned to the materials shown on the boring logs and referenced within this report <br /> were based on: (1) a review of available historic information and aerial photographs, (2)visual <br /> classification of materials during excavation,and (3) available common knowledge of the geologic <br /> processes and environments that have impacted the site and surrounding area in the past.
