The base of this unit i.s observed in the recent s;eep face ncar the base of the slope. A section thickness of about dU feet is estimated for the clay/silts along this line. The clay/silts are underinin by a vcr}• dense, red- dish to tan-grey, medium sand stratum. The sands are interpreted to comprise the lowermost slope elevations. These sands are well bedded and are water bearing. Current sewer construction efforts are baing hindered by substantial ground water flow emanating from the dense sands. It would appear that these sands correlate with the materials encount,red at similar clevations in TP-4, 5, 6 and 7 in our previous exploratory efforts. Based on our interpretation of site topography, slope� and vegetation, it would appear that a str:itigraphic rel;itionship similar to the above � section exists along thc slopes within the �uhject lot arcas. Ground watcr activity is most prominent within thc basal sands along the lowermost siopc elev:itions. Iiowever, evidence of hillsidc scep�ge is indicated heloa �hout �•Icv:ition 400' , at or slightly :ibove the con- tact betwcen the upper sands and [hc hard clay/silt unit.
