Foundation building plans were not available at the time of providing this report. However, <br />based on a phone conversation with the project structural engineer (Tildin Engineering), <br />the maximum additional surcharge loads will not exceed 600 pounds per square foot for <br />over the exterior footings. <br />BACKGROUND AND PREVIOUS INVESTIGATIONS <br />GSI has reviewed various published reports and maps available in our library with respect <br />to the regional geology and geotechnical considerations (see Appendix A, References). <br />CURRENT INVESTIGATION <br />GSI's subsurface field investigation was performed on September 5, 2004. The <br />approximate locations of the exploratory excavations are shown on the Plot Plan, Plate 1. <br />A total of four (4) hollow stem auger borings were advanced to depths of approximately <br />21.5 to 51.5 feet. A GSI field engineer observed the excavation operations and collected <br />bulk and drive samples of materials encountered for visual examination and subsequent <br />laboratory testing. Drive samples were collected in a 2.4-inch inside diameter sampler <br />lined with 1 -inch-high brass rings. <br />Soils encountered in the borings were classified in general accordance with the Unified <br />Soil Classification System (USCS), as described in Appendix B. The logs of the Borings <br />are presented in Appendix B and are based on visual examination of the samples, <br />materials observed from the excavations, and results of laboratory tests. <br />EARTH MATERIALS <br />Earth materials encountered on the subject property included documented compacted fill <br />materials reported by Leroy Crandall & Associates (see Appendix A), which consisted of <br />silty sand, light brown to grayish brown, moist to very moist, and medium dense to dense <br />in consistency. The depth of encountered fill within the site is approximately 5 feet. <br />Quaternary age alluvial material was encountered in all borings excavated on the site. <br />The alluvial materials observed generally consist of grayish brown, light brown to grayish <br />green silty sand, silt and silty clay that were typically moist to very moist and stiff to <br />medium dense in consistency. <br />Pacific Development Group <br />1307 West Sunflower Avenue, Santa Ana <br />File:kervenandree\4900297681.foundshopctr <br />W.O. 4976-Al-OC <br />November 2,2005 <br />Page 3 <br />GeoSoils, Inc.
