Groundwater <br /> Groundwater was encountered in 5 of the 7 recent borings at depths ranging from of approximately 12 <br /> to 19 feet below existing grades at the time of this exploration.The elevations of the water encountered <br /> typically varied from approximately 946 to 950 feet MSL. However, based on nearby wetlands, it is our <br /> opinion that long-term groundwater levels at this site would likely approach elevations on the order of <br /> 954 to 956. <br /> Soil conditions are also conducive for perched water to occur at higher elevations across the site and <br /> water features including wetlands are present near this site which could also affect groundwater levels. <br /> In clayey soils,groundwater could take several days to stabilize in the boreholes and our boreholes were <br /> immediately backfilled.Seasonal and annual fluctuations of groundwater should also be anticipated. <br /> Piezometers or monitoring wells would be required to confirm if groundwater was present within the <br /> depths explored. <br /> C. Basis for Recommendations <br /> The proposed construction will include a two-story, residential structure and associated surface parking <br /> lots, drive ways, utilities,and biofiltration basins. <br /> Structural details for the proposed building have not been provided at this time.We understand that the <br /> building will be wood-framed construction supported on conventional spread foundations with a <br /> concrete slab-on-grade. Based upon information provided by the structural engineer, the building will <br /> have maximum individual (column)foundation loads of 30 kips and a maximum continuous(wall) <br /> foundation load of 2 kips per linear foot. If structural loads exceed these values, we should be contacted <br /> to review our recommendations. <br /> We understand a drive-under, entrance canopy will be built on the east side of the main building <br /> entrance. The canopy will have four column supports at its corners. <br /> BRAUN <br /> INTERTEC <br />
