H9 KLEINFELDER <br /> ` include interior streets and driveways, various concrete flatwork, alon sign, and various buried <br /> utilities. PY <br /> Since grading plans were not currently available, proposed cuts and fills are unknown at this <br /> time. However, as site topography is essentially level, cuts and fills during earthwork are <br /> anticipated to be minimal (3 feet or less) to provide level foundation pads with positive site <br /> drainage. Excavations for underground utilities are not anticipated to exceed 15 feet below final <br /> site grade. <br /> v <br /> Anticipated Subsurface Conditions <br /> Kleinfelder's Stockton office has performed several geotechnical studies in the project area. <br /> These include a preliminary study for the Mountain House development north of Grant Line <br /> Road, the transmission towers located along the west perimeter of the site, the future Calpine co- <br /> generation plant that will be located to the northwest, and various commercial warehouse <br /> structures to the south. Based on this experience, we anticipate the near-surface soils will consist <br /> predominantly of stiff to very-stiff, moderately-plastic clay underlain by interbedded strata of <br /> very-stiff to hard silt and clay and medium-dense to dense sand. Groundwater is anticipated <br /> within 15 to 20 feet of existing site grade. <br /> III.
