types in the field. Our explorations were approximately located in the field by measuring from ]rnown site features shown on the topognphic plot plan provided by Shockey/Brent, Inc. The conclusions and recommendations presented in �his report aze based, in part, on the explora�o:� p;ts completed for this study. The number, location, and depth of the explorations werc complete 3 within site and budgetary censtraints. Because of the nature of exploratory worl: below ground, extrapolation of subsurface conditions between field explorations i� necessary. T: should be noted that differing subsurface condidons may sometimes ►�e present dae io tne �andom nsture of deposidon and the alteration of topography by past grading andlor filIing. :1ie nature and extent of any variadons between the field explorauons may not become fi:llv evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific rtoommendations in this report and make appropriate changes. 3 1 Exoloration Pits Exploration pits were excavated with a track-mounted backhce. The pits permitted direct. v;sual observation of subsurface conditions. Materials encountered in the exploration pits were studied and classified in the field by an engineering geologist from our firm. All exploration pits were backfilled immediately after examination and logging. Selected samples were then transporced to our laboratory for farther visual classification and testing, as necessar,y. 4.0 SUBSURFACE CONDITIONS Subsurface conditions at the project site were infetted from the field exploradons accomplished for this study, visual reconnaissance of the site, review of topography provided on the previously mentioned topographic plot plan, and review of applicable geologic literature. As shown on the field logs, the exploration pits generally encountered up to 4�/z feet �f fill materials and organic topsoil or topsoil fill overlying medium dense to very dense glaciai sediments. The following section presents more detailed subsurface inforn►ation organized from the upper (younges!) to thP ]ower (oldest) sediment rypes. 4.1 Stratieraohv Fill Soils Fill soils (those not naturally placed) were encountered at the location of exploration pit EP-1. Exploration pit EP-1 was located in the steeply sloping area below the western half of the proposed duplex. The fill was approximately 3'h feet thick and generally consisted of loose to mediutn dense, moist to wet, tan to gray, silty sand with gravel and scattered cobbles, branches, and asphalt debris. Surface exposure of the fill was also observed at other locations within the azea of the steeply sloping, westem portion of the site. 3
