FINAL GEOTECHNICAL ENGINEERING REPORT PROPOSED EVERETT WAREHOUSE ASSOCIATED BOULEVARD AND INDUSTRY STREET EVERETT, WASHINGTON Project No. 2152.01 March 5, 2019 INTRODUCTION This report documents the surface and subsurface conditions encountered at the site and our geotechnical engineering recommendations for the proposed Everett Warehouse project. Our geotechnical engineering scope of services for the project included a literature review, site reconnaissance, subsurface exploration, laboratory testing, geotechnical engineering analysis, and preparation of this report. The observations and conclusions summarized herein are based in part upon conditions observed in our subsurface explorations, site observations, and proposed project plans at the time this report was prepared. This report is an instrument of service and has been prepared in general accordance with locally accepted geotechnical engineering practice. This report has been prepared for the exclusive use of HLD Properties, and its agents, for specific application to the subject property and stated purpose. PROJECT UNDERSTANDING Based on our review of progress drawings dated February 6, 2019 provided by the project civil engineer (PACLAND), we understand the project will consist of design and construction of a new, approximately 73,000 square foot warehouse building on a 4.35 acre site located in the southwest corner of the intersection of Industry Street with Associated Boulevard. Finished floor elevation of the warehouse is currently proposed at about elevation 426.5 feet. General site grading for the project is expected to consists of cuts with a maximum anticipated depth of 11 feet and fills with a maximum anticipated thickness of about 10 feet. Stormwater flow control for the project is currently proposed through a roughly 65,000 cubic foot underground stormwater detention vault located in the south portion of the site with a proposed bottom elevation of412.5 feet. The currently proposed site plan is depicted on the attached Figure 1. SURFACE CONDITIONS The project site consists of two parcels of undeveloped land totaling approximately 4.35 acres located in the southwest corner of the intersection of Industry Street and Associated Boulevard in Everett, Washington. The site is bordered to the north by Industry Street; the south by developed industrial property; to the east Page 1
