The field explore.tion program was based upon the i proposed construction and requirec' design criteria , site topography and access , subsurface conditions revealed during excavation, the scope of worlc ouLlined in our proposal , and � time and budget constraints . The test pits were excavated on october 4 , 1991 with a rubber- tired backhoe owned and operated by Evans Etrothers Excavating. A geotechnical engineer from our staff observed the excavation procr.ss, logged the test pits , and obtained representative samples of the soils encountared. "Grab" samples of selected i subsurface soils were collected frorti the backhoe �uckeC. The , Test Pit Logs are attached to this report as Plate 3 . ; �r � Test Pit 1 encountered 2 feet of loose to medium-dense topsoil `,,, , and silry sand overlying very stiff t.o hard silts at a depth ; of 2 to 4 feet. Dense sands were observed bc•low the silt, at a depth of 4 feet. Test Pit 2 encountered about 1 foot of i �.�� loose topsoil overlying dense, silty sands. i �� 7he final logs represe�t our interpretations of the field logs nnd laboratory tests . The stratification ; ines on the logs �, i represent the approximate boundary bet -een soil types at the �'1- exploratior, locations. The actual transition between soil types may be yradual and subsurface ccnditions may vary between explor:+tion locations . The relative densities and moisture descriptions indica�ed on the test pit logs are interpretive de;:criptions based on the conditions observed �.� duriny excavation. The logs sh�uld be reviewed for specific subsurface informatinn at the locatiors tested . ' �...� � . r.aOUNDWATER II No groundwater seepage was cbserved in our explorations . The test pits were left opE� only for a short time period, 1 �,��( therefore, the lack of seepage levels on the logs does not ` "� necessarily indicate that water s�eepage w: ll not be • encountered. It. should be noted that groundwater levels vary seasonally with rainfall and other factors . We anticipate that groundwater could be found between the near-surface weathered soils , and the underlying denser soils . � GEO�ECH CONSULTANTS, INC.
