Environmental Review for VISION 2050

As part of the VISION 2050 development process, PSRC reviewed the environmental impacts of the plan alternatives.

PSRC reviewed the environmental impacts of the VISION 2050 plan alternatives in a supplemental environmental impact statement (SEIS). The SEIS was prepared in accordance with the State Environmental Policy Act. The SEIS contains new information and analysis and builds on data and analysis contained in the VISION 2040 Final Environmental Impact Statement and other existing environmental documents.

The Final SEIS (see links below) evaluates the environmental effects of four regional growth alternatives that distribute growth in unique patterns throughout the region. It contains updated environmental analysis, comments on the Draft SEIS, and responses to those comments.

The PSRC Executive Board will complete its review of the VISION 2050 plan and Final SEIS and, in turn, make its recommendation to PSRC’s General Assembly. Action by the Executive Board on VISION 2050 was delayed as a result due to COVID-19 and restrictions on in-person meetings. The Executive Board is meeting in July to continue discussing VISION 2050, with action to follow at a subsequent meeting. Follow the Executive Board’s meetings here.

Background

To help shape the plan and environmental review, PSRC held a public scoping period from February 2 to March 19, 2018. The scoping notice, comments received, and summary of the process and comments received are available below.

A Draft SEIS was issued on February 28, 2019, followed by a 60-day comment period. The Draft SEIS and comments on the Draft SEIS are provided below. Responses to those comments are provided in Appendix I of the Final SEIS.

In addition to information provided in the Draft SEIS, the Growth Management Policy Board used several tools to develop the Preferred Growth Alternative:

  • Summary of Draft SEIS public comments
  • Supplemental technical evaluation
  • Board priorities based on discussions at board meetings

The Preferred Growth Alternative in the Final SEIS is presented as the Regional Growth Strategy in in the Growth Management Policy Board's recommended VISION 2050.

Equity Analysis

The SEIS includes an equity analysis to evaluate how the alternatives may affect people of color and people with low incomes on issues like land use, transportation, and housing. The Final SEIS identifies potential impacts to these communities, along with mitigation measures and information on demographics in the region.
