This work was authorized by you on <br />March I, 1993. Our .scope of sci vices you rapicsted consisted of i>erforming seven (7) standard <br />jieneuation borings ranging from 12’ to 35’ below the ground suiface. <br />Ihe subsurface exploration program was ^*erformed in general accordance with the applicable <br />American Sinndard for TesUng and Materials (ASTM) procedures, as described in the <br />altachmenl. <br />The test loottons were slaked and selected by you. We have atuched a sketch of the general <br />oca ions. Tlie surface elevations were Liken from the contour elevations shown on the plan you <br />provided to us. Generally, the surface elevations ranged 956’ to 960’. <br />glaci^t ’ll^ stiggesl a soil profile consists of swamp dc|>osils underlain by sandy lean clay <br />Water level measurements were also taken in the open boreholes during and at the completion <br />ot die drilling process. As indicated on the attached boring logs, groundwater water was <br />measured to be within 1’ of the surface at the lime and location of the borings. <br />If you have any questions regarding this letter, or if wo may be of further assistance, please call <br />me at (612) 659-7405.
