Today, the Seattle Seattle Department of Transportation determined that the retrofitting of Ballard Bridge is "not likely to have significant adverse impacts on the environment", allowing the project to move forward.

SDOT issued a Determination of Non-significance (DNS) today after review of the proposal's potential impacts on several elements of the environment.

Comments on the DNS and checklist may be submitted until 5:00 pm Monday, April 25. 
In addition, any interested person may appeal this DNS by submitting a Notice of Appeal and a filing fee to the Office of the Hearing Examiner no later than 5:00 pm Monday, May 2.  Please see the DNS for more information on providing comments and submitting appeals.
