The Regional Transportation Plan (RTP) is the long-range transportation plan for the central Puget Sound region. The RTP is adopted every four years, and is designed to implement the region’s growth plan, VISION 2050. The RTP meets all state and federal requirements and is based on the latest data, adopted land use assumptions, and technical tools. 

The plan was developed over the last two years with extensive engagement with board members, technical committees, member jurisdictions, and the public. The plan implements the polices and goals in VISION 2050, outlining investments the region is making in transit, rail, ferry, streets and highways, freight, bicycle and pedestrian facilities, and other systems to ensure the safe and efficient movement of people and goods.

On April 28, 2022, the PSRC Executive Board unanimously recommended adoption of the Regional Transportation Plan for action by the General Assembly. The General Assembly adopted the plan on May 26, 2022.

Environmental Review for the Regional Transportation Plan

To support the Regional Transportation Plan 2022-2050, the Puget Sound Regional Council (PSRC) has prepared an addendum to the VISION 2050 Final Supplemental Environmental Impact Statement (SEIS) and is adopting the SEIS as part of the issuance of the addendum pursuant to the provisions of WAC 197-11-630.

The addendum summarizes project additions and changes included in the Regional Transportation Plan, discusses the potential environmental impacts associated with the updates, and identifies differences in impacts from what was identified in the SEIS. PSRC’s General Assembly is expected to take final action on the Regional Transportation Plan on May 26, 2022.

Paper copies and other assistance can be requested by contacting PSRC’s Information Center at 206-464-7532 or Appeals of the adequacy of the addendum must be received in writing by PSRC and postmarked by April 20, 2022. Information on submitting an appeal can be found on our SEPA Information page.

The SEPA Background Memorandum was shared at the Transportation Policy Board meeting on July 9, 2020. The VISION 2050 Environmental Impact Statement includes an analysis of the Regional Transportation Plan extended to the year 2050.
