GEOTECHNICAL ENGINEERING STUDY E-6893-1 McDonald's Corporation Page 2 June 9, 1995 SITE CONDITIONS Surface The site of the proposed facility is located at the intersection of 19th Avenue Southeast and 96th Place Southeast in Everett, Washington (see Plate 1, Vicinity Map). The rectangular parcel encompasses about eight tenths (0.8) of an acre. The site is bounded to the north by vacant property, to the east by 19th Avenue Southeast, to the south by an existing restaurant, and to the west by the right-of-way for Interstate 5. The property is covered by a dense growth of Scotch Broom. Two mounds of miscellaneous fill were observed on the site One large mound in the southwest corner and a smaller mound in the northeast portion of the parcel. The appruximate locations of the fill mounds are shown on the Test Pit L—ation Plan, Plate 2. Fill consisted of wood, concrete and asphalt debris and metal strapping. Surface drainage is from east to west with a topographic drop of approximately three feet across the site. Subsurface The site was explored by excavating six test pits at the approximate locations shown on Plate 2. Detailed descriptions of the conditions encountered at each location explored are presented on the test pit logs, Plates A2 through A7. A description of the field exploration methods is included in Appendix A. Following is a generalized description of the subsurface conditions encountered. In general, we observed a 4- to 12-inch layer of topsoil overlying a silty sand with gravel (Unified Soil Classification SM). The topsoil was in a loose condition and had a high organic content. The silty sand underlying the topsoil was dense to depths ranging from two to five feet beneath existing grades. At these depths, the silty sand became very dense to the maximum exploration depth of ten feet beneath existing grades. Earth Conmhanta, Inc.
