I-405 Congestion Relief & Bus Rapid Transit Projects- Renton Nickel Improvement Project Environmental Assessment

In October 2006, WSDOT published an Environmental Assessment for the Renton Nickel Improvement Project. The Environmental Assessment contains the results of our studies on how this project may affect the environment.

The Federal Highway Administration analyzed our Environmental Assessment and in  issues a Finding of No Significant Impact (FONSI) for this project. The FONSI presents the reasons why building this project will not have a significant effect on the environment and therefore does not require that we prepare an Environmental Impact Statement.

We published a Notice of Availability for the FONSI on January 31, 2007, and below you can download the FONSI in Adobe Acrobat portable document format (.pdf).
