i SHANNON F�WILSON,INC. I seepage was occasionally observed in this layer or at the contact of this soil and the underlying 611-like soils. iThe glacial, till-like soils observed in our acplontions consisted of dense to very dense with depth, brawn (occasionally light gray), trace of gTavel W grevelly, silty sand and sandy silt, ( with occasional trace of clay and int�rbedded wet seams of sand. Thesc soils weie underlain by glacial till, which was denser and dark gray in color. Thin layecs of wet, medium dense � to dense, silty, sandy gravel were encountered above the Gll-like soils in test pits TP-2 and TP-4. IGroundwater was encountered in sevecal explorations. It was generally encountered perched on top of dense to very densc, relatively impervious till-like soils. As no seepage wes obscrved on the slope, the groundwater observed is believed to be pe�hed rather than part of the condnuous groundwater table. These levels and locafions should only be considered i reasonably accurate at the exploraGon locadons measured and at the time of ineasurement. Seasonal groundwater fluctuadons are andcipated w occur. For example, during periods of I heavy iain, the occurrence and quan6ty of perched groundwater would tend to incnease, in our opinion. It should be noted that glacial till-like soils also wntained seams of rela6vely pervious wet soils that could yield reladvely significant quandties of watec Isolated seepage Iwnes were also observed within the fill or weathered native soils, especially around the wood debris. I8.0 �NCLUSIONS AND RECOMMENDATIONS I Based on the results of our explora6ons and studies and our discussions with the design team, it is our opinion that the site is suitable for deveiopment and construction of the pmposed facilitics. Our major recommenda6ons az�e summarized below: I ► Dc,welopment of the upper plateau of the sitc, as shown on Figure 1, should not create a hazard to the subject property. ► Development of the site, as shown in Figure 1, will not decrease the stability of I the slope, in our opinion. Instead, collecting and controlling surFace water upslope as part of site development and preventing its flow over the slope will I W-6693-01 8
