The attached report presents our findings and recommendations for the geotechnical aspects of project design and construction. Soil conditions observed in the test pits and CPTs at the site consist of 4.5 feet to 8.5 feet of fill overlying native alluvial soils. The alluvial soils consist of sands underlain by a 10- to 12-foot thick layer of soft, compressible silt and clay that is in turn underlain by medium dense to dense sands. Groundwater was encountered at depths ranging from 5 feet to 12.8 feet. In our opinion, soil and groundwater conditions at the site will be suitable for support of the development as plannedprovided recommendations contained herein are incorporated into project designand construction 1 2P specifications. Site preparation to mitigate potential building settlements due to consolidation of the organic silt layer consists of ground improvement by surcharging the building pad area. I We trust the information provided in the attached report is sufficient for your current needs. If you have any questions or need additional information,please call.
