The attached report <br /> ' presents our findings and recommendations for the geotechnical aspects of project design and construction. <br /> Soil conditions interpreted from CPTs at the site consist of 3 feet to 8 feet of fill overlying native alluvial soils. <br /> ' The alluvial soils consist of sands underlain by a 4- to l 1-foot thick layer of soft, compressible silt and clay that <br /> is in turn underlain by medium dense to dense sands. Groundwater is interpreted from 2 of the CPTs to be at <br /> depths of 4.8 feet and 10.7 feet. <br /> ' In our opinion, soil and groundwater conditions at the site will be suitable for support of the development as <br /> planned provided recommendations contained herein are incorporated into project design and construction <br /> specifications. Site preparation to mitigate potential building settlements due to consolidation of the soft silt/clay <br /> consists of ground improvement by surcharging the building pad area. <br /> We trust the information provided in the attached report is sufficient for your current needs. If you have any <br /> questions or need additional information, please call. <br /> Sincerely yours, <br /> TERRA ASSOCIATES,INC. <br /> ' Kevin P.
