Transit Master Plan

February 16, 2012

What’s New?

Final plan development
The public comment period for the Transit Master Plan draft summary report has closed. We're currently reviewing comments and incorporating changes into the final draft. We plan on transmitting a final draft to Council in mid-February and will attend the March 13 Transportation Committee meeting.

SEPA determination of non-significance
SDOT has completed an environmental review of the proposed Transit Master Plan under the State Environmental Policy Act (SEPA) and has determined that the proposal is not likely to have significant adverse impacts on the environment. As a result, we issued a Determination of Non-significance (DNS) on February 16, 2012. This decision was made after reviewing the proposal's potential impacts on several elements of the environment, summarized in this SEPA environmental checklist. Public comments on the DNS and checklist are welcome through March 1, 2012. Please see the DNS for more details.

What is the Transit Master Plan?

The Seattle Department of Transportation is developing the city’s next generation Transit Master Plan (TMP). The TMP will be a comprehensive and 20-year look ahead to the type of transit system that will be required to meet Seattle’s transit needs through 2030. Nelson\Nygaard Consulting Associates, nationally acclaimed experts in transit planning, will assist SDOT in developing the TMP.

The Transit Master Plan will be an extensive update to the 2005 Seattle Transit Plan, which identified key corridors linking urban villages and established performance standards for transit service. The TMP will expand on that work and include evaluation of rail modes, rapid bus services, station design, and capital infrastructure.

The Transit Master Plan will address many critical issues:

  • Identifying the city’s most important transit corridors that carry high ridership today, as well as potential new ridership markets that will emerge as Seattle grows in jobs and new residents
  • Assigning transit modes—such as bus rapid transit, light rail, or street car—that would work best on those corridors
  • Integrating transit capital facilities and services with walking and biking infrastructure, and using transit to make great places
  • Enhancing bus transit performance through roadway investments such as bus bulbs and traffic signal priority
  • Coordinating with Metro and Sound Transit to create a seamless, fully integrated, and user friendly network of transit services

What is the current status of the TMP?

The first phase of the Transit Master Plan was completed in February 2011. As part of this work, the Briefing Book: State of Transit in Seattle, was published in December of 2010. This phase also identified a framework for identifying and prioritizing corridors for future investment. This second phase of work, encompassed in the TMP Draft Summary Report, was completed in late September. The next step is getting public feedback to inform a final plan that will be adopted by the City Council in early 2012.
