Results 13.1.• Site Conditions The site is an approximate 5 -acre, rectangular- shaped property located along the south side of County Road B2, west of Greenbrier Circle. As shown on Figure ], there are a two existing homes, a detached garage and a shed on the site, with ravel driveways off of County Road B2. The site is a combination of scattered brushy woods, larger trees, and open lawn space. The site is elevated where the exiling homes are located and slopes down w the north and east away from the homes. There is a drainage ditch along the east side of the she that drains northward beneath County Road B2 via a culvert. At the time of our evaluation, there was some standing water in the ditch. 13.2. Logs' Log of Boring sheets are contained within the Appendix. These logs indicate the depths and identifications of the various soil strata encountered includingpenetration resistances, ground surface elevations and groundwater observations. Where shown, strata changes were inferred from changes in the panetration. te$t samples. It should be noted that the depths ehnwn as ehanneg between the strata are only approximate. The changes are likely transitions and the depths of the changes likely vary away from the borings. Geologic origins presented for each stratum on the Log the soil types, blows per foot, and available corarnon knowledge of the depositional history of the area. 33.3. Soils Encountered B.3.a. Topsoil. Topsoil, on the order of about f /,- to 1'/ -feet thick, was encountered at the surface. The topsoil consisted of sandy lean clay (CL) that was dark brown, moist and contained roots. 113.b. Swamp and Lake Deposits. Beneath the topsoil, Borings ST -1, ST -2 and ST-4 encountered swamp and lake deposits to a depth of approximately 9 fax. At Boring ST -2, this material may have been artificially placed (existing fill) as opposed to naturally - deposited. The swamp deposits consisted of slightly organic lean clay (CL) and silty clay (CL-ML), organic silt (OL), and peat (PT). These organic materials were wet, gray and black, and often fibrous, The lake deposits, in contrast, consisted of silty sand (SM) and clayey sand (SC). These sands were wet, light gray and often contained fibers and shells. p.7
