• AET #95-1343 - Page 3 <br /> Soils <br /> Logs of the test borings are attached. The logs contain information concerning soil layering, <br /> soil classification, geologic description and moisture. Relative density or consistency is also <br /> noted, which is based on the standard penetration resistance (N-value). <br /> • <br /> • The boring logs only indicate the subsurface conditions at the sampled locations and variations often <br /> occur between and beyond borings. <br /> The generalized geologic profile at the sites consists of about 21/2' to 8' of fill overlying peat <br /> swamp deposits, in turn underlain by water-deposited (alluvial) sandy soils. <br /> • The fill soils are mostly fine grained silty sands, which are sometimes intermixed <br /> with peat and organic clay. Some sandy lean clays and lean clays are also <br /> • present. Generally, the fill soils appear to be moderately compact, based on N- <br /> values; although fill stability appears to be relatively low due to the inclusions of <br /> organic and wet clayey soils. <br /> • The swamp deposits are mostly hemic peat, with zones of organic clay and fibric <br /> peat. Borings #4 and #5 did not extend deep enough to penetrate the peat, and <br /> in fact, Boring #4 did not reach the natural swamp deposit. In the field area, the <br /> peat extends to depths ranging from 71/2' (at Boring #2) to at least 21' (Boring #3 <br /> terminated in peat at 21'). <br /> • The coarse alluvium is classified as silty sand or sand with silt, which is mostly <br /> fine grained. <br /> • <br />
