Project Description
This project will upgrade the West Seattle Stadium to current accessibility standards, including improvement to accessible routes, parking stalls, providing wheelchair seating and a platform lift to the south concrete grandstands, restroom and interior improvements and Site Work. Site Work includes new concrete ramps, plazas, asphalt parking stalls, landscaping and irrigation improvements, and a new detention vault. This project also includes 2 Additives that we will be doing as well. Additive 1 covers Epoxy Flooring over sealed concrete in the restrooms. Additive 2 includes construction of an additional ramp from the parking area to the concrete bleacher structure.
During construction, the contractor will need to close a portion of the track near the Grandstands. Seattle Parks and Recreation and the Contractor hired for the project will work to minimize the impact on the track & field.
