Groundwater Groundwater seepage levels observed while drilling are shown on the boring logs. Generally the le•�els ranged Erom about five (5) to seventeen and one-half (17.5) feet below the existing ground surface. Where encountered, the elevation of seepage occurred between Elev. 595 and Elev. 606. Slotted standpipes were installed in Borings B-1, B-2, B-3 and B-6 to allow subsequent measurement of groundwater levPls. The groundwater seepage level is not static and fluctuations in the elevation and flow zate should be expected depending on the amount of rainfall, surface water runoff, and other factors. Generally the water level is higher in the wetter winter months. DISCUSSION AND RECOP44ENDATI02�I5 General In general, three different soil conditions are anticipated at footing bearinr elevations. In the vicinity of the existiny building and south to the northeast corner of tdervyn's, new imported fill will be required to raise the site grade. The western one-half of Mervyn's and Shops "B" will most likely bear on dense till. The Drug Emporium b�ilding, which will bear on medium dense weathered till is also included in this category. The third bearing condition occurs at the southeastern quadrant of Mervyn's sto-e where footings will be founded in existina loose to medium dense fills. Transitional bearing conditions will occur between these general areas, and localized zones of differing conditions should be expected. Recommendati.ons are provided for the dense till bearing condition and for footings founded on new or existing fill. Due to the moisture sensitivity of fine-grained existing fills, it is recommended that they be replaced with imported granular material for a depth of two feet below the footing. :m
