Page 4 - #4220 91-1043 <br />`" The fill encountered consists primarily of a mixture of lean clay and sandy lean clay <br /> ranging in color from brown to dark brown and black. The fill at boring #3 also ' <br /> contains some clayey sand and silty sand. Based on the penetration resistance (N- <br />-- value), portions of the fill appear to be in a relatively well-compacted condition while <br /> other portions, primarily the fill encountered at borings #1 and #2 as well as surficial <br /> fill at boring #3, appear to be in a loose condition. At borings #1 and #2, topsoil <br />— consisting of silty clay and lean clay ranging in thickness from 1/2' to 2' was encountered <br /> beneath the fi1L <br />- At borings #1 and #3, fine alluvium consisting of dark grayish brown and light gray lean <br /> clay was encountered beneath the surficial fill and topsoil. Based on the penetration <br /> resistance (N-value) the �ne alluvium ranged in consistency from very soft to soft. <br /> . Underlying the surficial fill, topsoil and fine alluvium, weathered till and till consisting <br /> V primarily of sandy lean clay and clayey sand was encountered to the depth of the <br />_ borings. These cohesive soils contain some lenses of waterbearing sand and silty sand. <br /> Based on the penetration resistance (N-value) the weathered till ranged from soft to <br />� rather stiff while the underlying till generally ranged from firm to hard. <br />; <br /> 2.4 Water Levels <br />' The boreholes were checked for the occurrence of water during and shortly after <br /> completion of our test borings. Groundwater was encountered at the boring locations <br />
