Exploratory borings were drilled on 8-19-2024 using a 4-inch diameter continuous flight power auger. 2. No free water was encountered at the time of drilling or when re-checked the following day. 3. Boring locations were taped from existing features and elevations extrapolated from the final design schematic plan. 4. These logs are subject to the limitations, conclusions, and recommendations in this report. 5. Results of tests conducted on samples recovered are reported on the logs.
