SEPA Checklist, Technical Memoranda, and SEPA Threshold Determination

Publish Date

Sound Transit has prepared a State Environmental Policy Act (SEPA) environmental checklist for the SR 522/NE 145th Bus Rapid Transit (BRT) project. Along with the environmental checklist, Sound Transit developed conceptual plans and technical reports on the following: 

  • Noise and Vibration
  • Ecosystem Resources
  • Air Quality
  • Transportation
  • Visual and Aesthetic Resources
  • Historic and Cultural Preservation

Sound Transit issued a Determination of Nonsignificance (DNS) for the SR 522/NE 145th BRT project on March 25, 2021. Based on the checklist, technical reports and other information, Sound Transit has determined the project does not have a probable significant adverse impact on the environment. Comments on the DNS must be submitted by 5:00pm on April 8, 2021. The environmental analysis will inform the Sound Transit Board on future decisions about the project.

For additional information on how to submit comments, see the DNS posted on the Sound Transit SR 522/NE 145th BRT Documents page.

SR 522/NE 145th BRT Project

Sound Transit is proposing to implement new bus rapid transit (BRT) service along SR 522 and NE 145th Street. This service will operate between Sound Transit’s Link light rail Shoreline South/148th Station and a new transit hub to be constructed by the Washington State Department of Transportation at the SR 522/I-405 interchange. Sound Transit proposes to construct 12 BRT transit stations along the nine-mile service route, together with three park-and-ride garages (Bothell, Kenmore, Lake Forest Park). To facilitate bus speed and reliability, the project would construct road improvements, including new business access and transit (BAT) lanes, bus-only lanes, and bus queue bypass lanes, at various locations along approximately four miles of the corridor. In addition, the project would construct/reconstruct sidewalks and driveways in some locations, and would include stormwater infrastructure and landscaping.
