Vegetation con- �' sists of landscaping materials, lawn and some trees, with the ma�ority of � ' the area in lawn. The southwestern portion occurs within an area of trees. � � Topographically, the area is generally flat l,ying, with a very gentle slope � + taward the southeast. � � Soils Conditians � � The subsurface soils stratigraphy can best be seen on the enclosed test ' pit logs. w In geneTal , the site was found to be underlain at depth by grey, dense, ' poorly sorted s11ty sand with gravel , consldered to be glacial till. Thc�e 4i soils were encountered at depths ranging from 3' to greater than 4.5' below � grade. Overlying the glacial till is a 0.5' to 1.5' thick strata of brown �_ to grey-brown, medium dense poorly sorted gravelly sand. This material appears to consist of residual glacial outwash soils. These soils are generally very granular, although were found to be much less dense than the � underlying glacial till. Soils overlying the gravelly sands varied across the site. Within some areas (TP-1 , TP-2, TP-3) the gravelly sands were overlain by red-brown loose gravelly silty sand with roots and brown-black intermixed organic ladden silty sand, considered artificial ffil. Other areas were found to consist of surfictal soils previousl�• described without the artificial fill, although an organic topsoil layer was present. These -- areas were determined to consist of surficial soils ranging in thickness from 2.0' to 3.0' across the site area. Since artificial fill soils were encoun- tered within the area, some areas of thicker unsuitable surficial soils ` may be encountered. w.
