<br />March 2000 -25- 993-2099.150 <br />The test pits were excavated to depths ranging from 7 to 20 feet. Weathered bedrock was <br />encountered in the majority of the test pits at depths ranging from 7 to 17 feet. The soils <br />encountered in these test pits typically consisted of growth medium (upper 1 foot) <br />underlain by silty sands, silty gravels, clayey sands and clayey gravels. These soils <br />classify as SM, GM, SC, and GC, respectively, under the USCS. Ground water was not <br />encountered in any of the test pit excavations. <br />In the 1998 geotechnical investigation, twelve Becker Hammer boreholes were drilled with <br />Becker Hammer data recorded for each hole (BH98-1, BH98-2, BH98-3, BH98, <br />BH98-5, BH98-6, BH98-7, BH98-8, BH98-9, BH98-10, BH98-11 AND BH98-12). Three <br />companion holes (BH98-2COMP, BH98-9COMP and BH98-12COMP) were drilled to <br />obtain soil samples. All of the boreholes were drilled to the north of existing Highway 67, <br />within the general limits of the Phase IV VLF to evaluate foundation conditions. <br />Depths to bedrock were recorded as part of the underground working field investigation, <br />and are summarized in Table 3. The locations of the drillholes are shown in Appendix D. <br />The depth to bedrock in the drillholes ranged from 2 feet, to a maximum of 50 feet in the <br />eastern drainage. The average depth of bedrock encountered in the drillholes was 16 feet. <br />CJ <br />Ground water was not encountered in any of these boreholes. <br />is\99\]099\FINAL REPORT3099MAIN3DOC Golder Associates <br />
