f Below the pavement or topsoil boring SB-lencountered about 6 feet of clayey sand and silty clay fill that extended to a depth of about 7 feet. Boring SB-2 encountered about 1 foot of sandy lean clay fill that extended to a depth of about 2 feet. Below the fill both borings encountered organic silt (swamp deposits) that extended to a depth of about 12 feet at boring SB-1 and 4 feet at boring SB-2. Underlying the pavement section,fill and/or organic silt the borings encountered sandy lean clay glacial till soils that extended to the boring termination depths at about 21 feet below the ground surface. The penetration resistance values (N-Values), shown as blows per foot (bp fl on the boring logs,within the clay glacial till soiLs ranged from 5 to 17 bpf. These values indicate the clays to have a medium to very stiff consistency with some upper soft zones. 3.2 Groundwater Groundwater was encountered in boring SB-1 at a depth of about 8 feet while drilling and at a depth of about 5 feet after drilling,which corresponds to elevations of about 9241/z and 9271/z feet,respectively. Groundwater was not encountered in boring SB-2 while drilling or after removing the augers from the borehole to a cave-in depth of 12 feet. The ordinary high water level of Lake Minnetonka is 929.4 feet. The soil borings were completed in clayey soils and given the cohesive nature of the site soils it is likely that insufficient time was available for groundwater to seep into the borings and rise to its hydrostatic level. Groundwater monitoring wells or piezometers in conjunction with deeper soil boring(s)would be required to more accurately determine water levels. Water levels were measured on the dates as noted on the boring logs and the period of water level observations was relatively short. Seasonal and annual fluctuations in the groundwater leveLs should be expected. 3.3 Laboratory Tests Laboratory moisture content tests were performed on selected samples recovered from the soil borings. Table 1 below summarizes the results of the laboratory tests. Results of the laboratory moisture content tests ranged from 16 1/z to 19 1/2 percent and are shown on the boring logs adjacent to the sample tested. Table 1.
