The preceding is a generalized description of soil conditions at this site. Variations from the generalized <br />profile exist and should be assessed from the boring logs, the normal geologic character of the deposits, <br />and the soils uncovered during site excavation. <br />3.4 Groundwater Conditions <br />WSB took groundwater level readings in the exploratory borings, reviewed the data obtained, and <br />discussed its interpretation of the data in the text of the report. Note that groundwater levels may <br />fluctuate due to seasonal variations (e.g. precipitation, snowmelt and rainfall) and/or other factors not <br />evident at the time of measurement. The bore holes were only left open a short period of time, and <br />groundwater levels may not have had time to stabilize. <br />Table 2 below is a summary of the estimated water levels at our borings. <br />Table 2: Estimated Groundwater Elevations <br />Boring <br />No. <br />Ground <br />Surface <br />Elevation <br />Depth to Groundwater <br />after Drilling <br />Estimated Groundwater Elevation <br />PB -1 <br />936.6 <br />n/a <br />Below 922 '/2 <br />PB -2 <br />938.5 <br />n/a <br />Below 924 <br />PB -3 <br />938.4 <br />14 <br />9241/2 <br />PB -4 <br />936.9 <br />11 '/2 <br />9251/2 <br />PB -5 <br />938.6 <br />12 <br />927 <br />PB -6 <br />940.3 <br />14 <br />926'/2 <br />PB -7 <br />939.0 <br />13 <br />926 <br />PB -8 <br />938.8 <br />14 <br />925 <br />PB -9 <br />940.6 <br />141/2 <br />9261/2 <br />PB -10 <br />942.5 <br />n/a <br />Below 928 <br />PB -11 <br />941.3 <br />n/a <br />Below 927 <br />PB -12 <br />943.0 <br />n/a <br />Below 928 '/2 <br />PB -13 <br />925.3 <br />19 <br />9201/2 (Top of Peat) <br />PB -14 <br />937.5 <br />n/a <br />Below 923 <br />PB -15 <br />936.9 <br />14 <br />923 <br />PB -16 <br />940.3 <br />14 <br />9261/2 <br />PB -17 <br />938.2 <br />10 <br />928'/2 <br />PB -18 <br />936.4 <br />11 <br />925'/2 <br />PB -19 <br />937.4 <br />11 <br />926'/2 <br />n/a — indicates ground water was not encountered. Elevations are rounded to the highest 1/2 foot. <br />Peat is deposited in shallow open water areas; therefore it is our opinion that the groundwater table would <br />be near or a few feet above the top of peat encountered in Boring PB -13. These groundwater elevations <br />could affect installation of underground utilities. <br />Geotechnical Report <br />Oneka Lake Boulevard and Harrow Avenue Improvements <br />Hugo, Minnesota <br />WSB Project No. 010893-000 <br />Page 4 <br />
