The N-values appear to indicate that these soils were probably not placed and <br /> ' compacted in thin lifts with the intent to support building construction. We judge the fill to be <br /> moderately slow to slow draining and moderately frost susceptible. <br /> ' ' <br /> "Alluvium or Fill" and "Till or Fill„ <br /> ' The N-values in these soils aze typically low to moderately low. If these soils are naturally <br /> deposited, we judge them to have low to moderately low strength and low to moderate <br /> 1 compressibility. If these soils are actually previously placed fill, we judge most of them to be <br /> poorly compacted, to have low stirength, and to be compressible. The sands in Boring#1 appear <br /> , to be moderately well compacted• The clayey sands and sandy lean clays are judged to be slow <br /> drainitng.
