APPENDIX A <br />The field study was performed on August 17, 2004. The field study consisted of logging and <br />sampling the soils encountered in four (4) test borings. The approximate locations of the test <br />borings are shown on Figure 2. The log of the soils encountered in the test borings, are presented <br />on Figures AZ and A5. _ <br />The test borings were logged by Lambert and Associates and samples of significant soil types <br />were obtained. The samples were obtained from the test borings using a hand driven sleeve <br />sampler. <br />The test borings were logged by Lambert and Associates and samples of significant soil types <br />were obtained. The samples were obtained from the test borings using a Modified California <br />Bartel sampler and bulk disturbed samples were obtained. Penetration blow counts were <br />determined using a 140 pound hammer free falling 30 inches. The blow counts are presented on <br />the logs of the test borings such as 8/6 where eight (8) blows with the hammer were required to <br />drive the sampler six (6) inches. <br />The engineering field description and major soil classification aze based on our interpretation of <br />the materials encountered and are prepared according to the Unified Soil Classification System, <br />ASTM D2488. The description and classification which appear on the test boring log is intended <br />to be that which most accurately describes a given interval of the test boring (frequently an interval <br />of several feet). Occasionally discrepancies occur in the Unified Soil Classification System <br />nomenclature between an interval of the soil log and a particulaz sample in the interval. For <br />example, an interval on the test boring log maybe identified as a silty sand (SM) while one sample <br />taken within the interval may have individually been identified as a sandy silt (ML). This <br />discrepancy is frequently allowed to remain to emphasize the occurrence of local textural <br />variations in the interval. <br />The stratification lines presented on the logs are intended to present our interpretation of the <br />subsurface conditions encountered in the test borings. The stratification lines represent the <br />approximate boundary between soil types and the transition may be gradual. <br />~tSTCT~T$I t ~IYC~Y II~CCFS;tEB <br />CONSULTING GEOTECEINICAL ENGINEERS AND <br />AZ MATERIALS TESTING <br />
