1. Project Overview The 35-acre Riverside Business Park development project site is located at 505 East Marine View Drive adjacent to the Snohomish River in Everett, Washington. This project includes the construction of Public Access Trail Segments C, D, F, J, and K with Viewpoints G and H (project), as stipulated in the 'Riverside Business Park Public Access Agreement Port of Everett and City of Everett' (Agreement), dated December 28, 2015. The Agreement is available under separate cover and not included as a part of this report. The proposed trail will connect the existing shoreline trail north of the Riverside Road overpass (Segment B) to the trail at the Eighth Street cul-de-sac (Segment 1), constructed with the Riverside Business Park Public Access Trails and Roadway Improvements project. See Appendix Al for a diagram showing the trail and viewpoint designations. The proposed trail site area generally follows the Snohomish River shoreline. This area is currently occupied ' by Himalayan Blackberries, Scotts Broom, and various grasses. Upland from the trail tract, the inland lots have been cleared by development projects currently under construction. The developed lots will contain and mitigate all drainage originated within. The proposed trail has been designed to match existing topography for ' the most part; therefore, during rainfall events runoff will follow the existing path over the trail on its way out to the Snohomish River. Part of the shoreline is also supported by wooden bulkheads in various states of repair. The Public Trails project does not include any upgrades to the existing bulkheads. The project proposes 2,690 linear feet of 10-foot-wide asphalt concrete shared use path with associated landscape improvements. The landscaping plans were developed based on the 1999 Conceptual Buffer Enhancement Plan, Riverside Industrial Park by Talasaea Consultants and on the shoreline environmental requirements described in the January 2018 Draft Riverside Business Park Public Access Trails Biological and Floodplain Assessment by Hart Crowser (Biological and Floodplain Assessment). See Appendix C1 for the Biological and Floodplain Assessment. Surface water management will be accomplished though grading. Finished grades will allow runoff to sheet flow over the proposed improvements directly to the Snohomish River while maintaining existing overflow paths. The project will disturb approximately 1.1 acres, excluding landscape improvements to the existing ground surface. The earthwork intent is a net zero export where excess soils are amended and reused to create landscaped and planted fill slopes as noted in the grading and drainage plans. Structural fill import is anticipated to support the trail pavement section if existing soils are not adequate. See Appendix A2 and A3 for existing and proposed condition site maps.
