Recent Progress
Nickel funding began in July 2003. The project will construct new noise walls in the vicinity of Roanoke Street in Seattle. The Legislature funded this project for construction only under the assumption that design plan had been completed. The budget plan and project schedule have been revised to include design phase. Contract Advertisement will be in early summer 2004 and construction will begin in late summer 2004. With the total budget of $3.5M, it is determined that the funding is not enough to construct all the noise walls stated in the Project Definition Summary and Statewide Noise Barrier Retrofit Ranking. Trade-offs will be made with the communities. Public outreach events were held in November and December 2003. Noise Analysis, Geotechnical Investigation, and Structural Analysis have been completed. Several preliminary noise wall concepts were presented during public outreach events.
