M99238GE • 2.2 Site Conditions The proposed pond site was vacant at the time of our field study. The proposed pond s'_te slopes down to the southeast with about thirty (30) feet of topographic relief across the proposed pond site. The Fire Mountain Canal is located southeast of the proposed pond site. The old State Highway 135 is located along the north- west side of the proposed pond site. 2.3 Subsurface Conditions The subsurface exploration consisted of observing, describing and sampling the soil materials encountered in four (4) auger advanced test borings. The approximate locations of the test borings are shown on Figure 2. The logs describing the soil materials encoun- tered in the test borings are presented in Appendix A. The soil materials encountered in the test borings consisted generally of sand and clay mixture with varying amounts of gravel and cobbles to a depth of about twenty-four (24) feet. No formational material was encountered in the test borings to a depth of twenty-four (24) feet, the maximum depth explored. No free subsurface water was encountered in the test borings at •the time of our field study. we anticipate that the free subsur- face water elevation may fluctuate with seasonal and other varying conditions. It is difficult to predict if unexpected subsurface conditions will be encountered during construction. Since such conditions may be found, we suggest that the owner and the contractor make provi- sions in their budget and construction schedule to accommodate unexpected subsurface conditions. 3.0 ON-SITE DEVELOPMENT CONSIDERATIONS we anticipate that the subsurface water elevation may fluctuate with seasonal and other varying conditions. Deep excavations may encounter soils that tend to cave or a possibility of subsurface water. If water is encountered, it may be necessary to dewater construction excavations to provide more suitable working condi- tions. Excavations should be well braced or sloped to prevent wall collapse. Federal, state and local safety codes should be ob- served. 3 \J ~l.ambert ana ~,~.sociates CONSUi9NG GEOiECM NICA~ ENGwEE RS AND rn siE RIAL TESTING
