1300 W MARINE VIEW DR WATERFRONT PLACE APARTMENTS Geotech Report 2022-10-25

• INTRODUCTION This report summarizes the results of GeoEngineers' geotechnical engineering services for the proposed Waterfront Place Apartments project located at the Port of Everett in Everett, Washington. The project consists of two four-story buildings and are separated by 14th Street.The development to the north occupies parcels A3,A4,and A10 and the site is bounded by Port Gardner Way(13th Street)to the north,West Marine View Drive to the east, 14th Street to the south,and Seiner Drive to the west.The development to the south occupies parcels A5,A9,and A13 and the site is bounded by 14th Street to the north,West Marine View to the east,and Seiner Drive to the south and west.The site is shown relative to surrounding physical features on Figure 1,Vicinity Map and Figure 2, Site Plan. The purpose of this report is to provide geotechnical engineering conclusions and recommendations for the design of the new development.GeoEngineers' geotechnical engineering services have been completed in general accordance with our services agreements executed September 1, 2016 and consist of: • reviewing available reports and studies for the site and surrounding area available from our files; ■ completing four borings, 21 cone penetration tests (CPTs) and perform laboratory tests to evaluate subsurface conditions; • providing International Building Code (IBC) 2015 seismic design criteria; • providing ground improvement and foundation recommendations, site development, temporary construction dewatering and permanent drainage of foundations and below-grade wall recommendations; ■ providing geotechnical recommendations for site improvements, utilities, and pavement/hardscape; a preparing a preliminary report; and a preparing a final report. PROJECT DESCRIPTION SeaLevel Properties plans to develop parcels A3,A4,A5,A9,A10,and A13 at the Port of Everett located at 1016 14th Street in Everett, Washington. We understand that current design concepts consist of two multi-family apartment buildings constructed at-grade with four levels above grade and associated surface parking to the east of the buildings. At this time, the buildings will consist entirely of wood-frame construction. Based on discussions with the project team,we understand that the project team has elected to use ground improvement with shallow foundations to support the proposed apartment buildings. The Port of Everett will be completing civil improvements consisting of utilities, roadway, curb and gutter, and sidewalks in advance of the proposed development.The improvements will need to be protected from adverse impacts from ground improvement operations. • GEOENGINEERS� May 31,2017 ' Page 1 File No.22360-003-00
