Geotechnical Engineering Evaluation lrerracon Broadway& 10th Starbucks Everett, WA January 9, 2014 Terracon Project No. 81135080 Advanced four exploratory borings (designated B-1 through B-4) at strategic locations across the site, to depths ranging up to about 211/2 feet below existing grades. Performed limited geotechnical laboratory testing on representative samples of the near- surface soils. Analyzed subsurface conditions in relation to the proposed development, and prepared this written report. The functional locations, elevations, and depths associated with our recent on-site explorations are summarized in Table 2, and their relative locations are illustrated on Figure 2. Appendix A describes our field exploration procedures, and Appendix B describes our laboratory testing procedures. TABLE 2 SUMMARY OF SITE EXPLORATION PROGRAM Functional Surface Termination Exploration Elevation Depth Location (feet) (feet) B-1 Proposed Drive-Through Lane 110.5 6'/2 B-2 Proposed Parking Area 106.5 6'/2 B-3 Proposed Building Footprint-- East 108 21'/2 B-4 Proposed Building Footprint--West 110 21% Note: All exploration depths and elevations should be regarded as only approximate values. Elevations estimated from Irrigation Plan by SRG Partnership Inc. provided by SCM Solutions. 3.0 SITE SETTING We obtained information concerning regional conditions in the site vicinity from a review of geologic maps published by the United States Geological Survey (USGS). Our research findings are discussed below, and excerpts from selected maps and photo files are contained in Appendix C. 3.1 Regional Geography The subject site is situated in a commercial area approximately 1 mile west of 1-5, and about 500 feet southeast of the southeast corner of Everett Community College. Regional surface grades descend to the east at a gentle gradient. Reliable -_ Responsive Convenient - Innovative 3
