). H. KLEINFELDER & ASSOCIATES File No. S-1805-2 <br /> May 5 , 1975 <br /> PAGE TWO <br /> FIELD STUDIES <br /> The test borings were drilled at this site on April 24, <br /> 1975 . The borings were made at the approximate locations <br /> shown on the Plot Plan, Plate I . All borings were drilled <br /> with 6-inch diameter continuous flight-auger type drilling <br /> equipment . <br /> The soil conditions encountered at the points explored <br /> in the borings consist of a surface stratum of brown sandy <br /> clay which extends to depths of approximately 3 to 32 feet <br /> below the present ground surface . This soil is underlain <br /> by interbedded strata of brown sandy silt and very silty fine <br /> sand, with some cemented zones , to approximate depths of 14 <br /> to 16 feet. Below that depth, the soil grades to brown fine <br /> to medium sand to approximate depths of 22 to 23 feet . Below <br /> that depth, strata of brown sandy silt were encountered which <br /> extend to the maximum depths explored. <br /> Groundwater was not encountered in any of the borings <br /> drilled for this study. It is possible , however, that the <br /> groundwater conditions at this site could vary at some time <br /> in the future due to changes in rainfall, groundwater with- <br /> drawal, or other factors not apparent at the time our borings <br /> were made . <br /> The above is a general summary of the soil conditions <br /> encountered in the four exploratory borings made for this <br /> study. More detailed descriptions of the soils are given on <br /> Plates III through VI. All soils have been classified according <br /> to the Unified Soil Classification System, described on Plate II. <br />
