• <br />• <br />• <br />of a Laroe, ancient erosion channel that was filled probably <br />during the Pleistocene Period under entirely different cli- <br />matic conditions. This erosion channel appears to be an <br />important geomorphic feature that can be traced within the <br />north-central part of the property; a minor, similar channel <br />can be seen on the north-west part of the property. <br />Geologic sections (Plates 3, 4, and 5) have been <br />developed through representative sections of the site. The <br />section locations are indicated on Plate 2. These sections <br />have been developed from topographic maps of the site prior <br />to construction of the fills, current topographic maps, geo- <br />technical mapping of the existing surface exposures, and the <br />results of our drilling and test pitting program. <br />2.3 GROUND WATER HYDROLOGY <br />Measurement of ground water levels within the borings <br />during and after our field investigation indicated that ground <br />water levels are quite low during winter. There were no seeps <br />of ground water at the site during the period of our field <br />investigation. We do not anticipate that normal seasonal <br />fluctuations of ground water levels will be large. The <br />measured water levels as noted on the boring logs and plotted <br />on the geologic sections show that ground water in the vicin- <br />ity of the fills and cuts in colluvial soils (borings B-1, <br />B-2, 6-3, B-4 and B-5) is either below the bottom of the bor- <br />ings or else within the bedrock. In either case, existing <br />ground water conditions are not expected to adversely in- <br />- 7 - <br />cca*wxo coNwinrw, wc. <br />
