These data have been <br /> reviewed and interpretapons made in the text of the reporL Note, <br /> however, that fluctuations in the goundwater level occur due to <br /> variations in rainfall, dde,,temperature, and other factors at the time <br /> measurements are made. <br /> Groundwater monitoring wells were installed during the environmental <br /> assessment of the property. Measurements made in November 1991 <br /> indicate that the �oundwater level is roughty at an elevation of 14 to <br /> 14'h feet at the site. The shallow �oundwater is under unconfined <br /> condidons. The direcdon of shallow groundwater flow appears to be to <br /> the north; however, orily one set of water level measurements was <br /> made. Due to the proximity of Puget Saund (bordering the properry to <br /> the west), it is possfbie that goundwater flow is aff'ected by the tides <br /> and may vary with time. <br /> As noted on the baring logs, the groundwater ]evel at the time of <br /> cin7ling (ATD) was roughly 6'fz to 9 feet below gade. This corresponds <br /> to elevations of 9 to il'i4 feet Groundwater ]evels measured this way <br /> aze less accurate than those taken from finished wells. <br /> GEOTECffi`IIC�,L �VGLYEERIlVG D�SIGN RECObII1�NllATIONS <br /> In this section we address site preparation and grading, foundations, <br /> s]abs-on-�ade, anticipated settlements, retaining walls, drainage, <br /> pavements, seismic considerations and other recommendations. <br /> Site Pmparation and Grading <br /> Initial preparation of the site for building construc6on and pavement <br /> support should include demolition of temporary structures, their <br /> foundations, and pavements.
