� GEOTECHNICAL ENGINEERING STUDY Taco Bell Corporation April 29, 1993 �. � Surface � E-6140 Page 2 The site of the proposed facility is located northeast of the intersection of Evergreen Way and 75th Street southeast in Everett, Washington.(see Plate 1, Vicinity Map). ThQ rectangular shaped parcel encompasses about one-half acre and is bounded by a single story restaurant to the north, 75th Street Southeast to the south, a singie family residence to the east and Evergreen Way to the west. During the time of our study, the western two-thirds section of the site was covered with three to four feet of soil stockpiles. These stockpiles are composed predominantly of a very loose and saturated brown siity sand intermixed with construction debris. The eastern one third section of the property is occupied by a one ,evel, wood frame, single family residence. Vegetation consisting of grass, trees and bushes was oniy observed around the residence located at the east side of the subject property. Subsurface 7he site was explored by excavating five test pits at the approximate locations shown on Piate 2. Refer to the test pit logs, Plates A2 to A6, for a detailed description of the conditions encountered at each location explored. A description of the field exploration methods is included in Appendix A of this report. Below is a generalized description of the subsurface conditions encountered. In general, during our site study, we encountered two to fourteen feet of fill soil composed predominantly of a very loose to medlum dense, bYown and gray silty sand with gravel, (Unif�ed Classificatian SM). At Test Pits TP-1, TP-3 and TP-4 located at the central west half of the site, (vicinity of proposed building), the fill soil ranged from eight to fourteen feet below the ground surface. Based on a discuasion with the present property owner, it is our understanding that the encountered fill found at the central west half of the site, was from backfilling an excavation after the removal of several underground storage tanks. At test pits TP-2 and TP-5 located along the north side of the site, we encountered fill soils ranging from two to three feet thick (soii stockpiled across the site). Underlying the layer of fill, we encountered native, brown and gray medium dense to very dense silty sand (SM) and sandy silt (ML►, to the maximum exploration depth of fourteen feet below the existing ground surface.
