DAVID L. NELSON AND ASSOCIATES, INC. Consulting Enginecring Geology March 11, 1985 Project No. 1485 Page two Location and Site Description The investigated site area consists of the northerly lot which has been short platted, located at 1019 Mukilteo aoulevard, in Everett, Washington. Presently this portion of the site is not developed. Vegetation consists of grasses, brush and blackberry vines. Topographically, the southern portion of the site is relatively flat lying, but breaks into a moderate to steep sloue to the north toward a stream area at the base. The approxi- mate top-of-slope line is shown on the location map. Soils Conditions 7he subsurface soils conditions can best be seen on the enclosed test pit logs. In general, the site area was fuund to be underlain by grey-brown to grey, medium dense to dense, poorly sorted to medium grained sand, with minor gravel. This basal material was found to occur at elevations below grade ranging from 2.5' to 8'. Overlying the basal dense sands is a strata of brown to grey-bro�an, loose to medium dense, poorly sorted to. medium grained sand. This strata is found to.vary in thickness from 2' to 4'. Overlying the medium dense sand is a 1.5' to 2' thick strata of brown loose silty sand with roots. A surficial thickness of artificial fill, ranging from 1' to 6' thick, was found generally throughout the site area. This fill is composed generally of brown to black, intermixed silt, sand, gravel, organic and rubble, and in some areas grey-brown loose silty sand, with minor organics. It appears that the top-of-slope and a portion of the slope area has been subjected to past filling operations. Hvdrologic Conditions The ground water tzble was not encountered within the areas explored by the test pits. Some evidence of outcropping ground water was observed along the toe-of-slope area, however, indicating the presence of ground water witii depth.
