Geotechnical Engineering Evaluation Evergreen Way Burger King Restaurant Development 8525 Evergreen Way Everett, Washington INTRODUCTION This report presents the results of our geotechnical engineering investigation and evaluation of the proposed Evergreen Way Burger King Restaurant Development project in Everett, Washington. The project site is located at 8525 Evergreen Way, as shown on the Vicinity Map in Figure 1. The parcel number for the property is 28041300103900. For our use in preparing this report, we were provided with a site plan titled "Burger King Restaurant," dated June 23, 2015 and prepared by 2812 Architecture, showing the existing and proposed conditions throughout the site. The property is relatively level and is currently occupied by an abandoned, single-story restaurant structure, with the remaining portion generally being covered with asphalt pavement. Project plans consist of removing the existing site structure and constructing a new restaurant structure with a slab-on- grade within the north-central portion of the property, along with associated underground utilities and paved parking throughout the property. Final grading or drainage plans had not been developed at the time this report was prepared. The existing site features are shown on the Site Plan in Figure 2. SCOPE The purpose of this study is to explore and characterize the site surface and subsurface conditions, and provide general recommendations for site development. Specifically, our scope of services included the following: 1. A review of available soil and geologic maps of the area. 2. Explored the subsurface soil and groundwater conditions within the site with three, up to 20-foot deep drilled borings using a truck-mounted drill rig. Drill rig was subcontracted by NGA. 3. Performing laboratory analyses on selected samples, as needed. 4. Providing preliminary recommendations for earthwork, including cuts and fills. 5. Providing recommendations for temporary and permanent slopes. 6. Providing recommendations for foundation support, slab on grade, and pavement subgrades. 7. Providing recommendations for retaining walls,as needed. 8. Providing preliminary recommendations for site drainage and erosion control. 9. Documenting the results of our findings, conclusions, and recommendations in a written geotechnical report. NELSON GEOTECHNICAL ASSOCIATES, INC.
