Final Environmental Impact Statement

The Columbia River Crossing Final Environmental Impact Statement (EIS) contains analyses of environmental and community effectsboth positive and negativeof the project. It also describes how the project will improve safety and transit while relieving congestion on Interstate 5 between Portland and Vancouver.

This document published on behalf of the Federal Highway Administration and Federal Transit Administration is the culmination of years of planning and design discussions with project sponsors, stakeholders and the public. It builds on analyses included in the Draft EIS published in 2008, comments on the Draft EIS, and public input received at more than 950 community briefings, workshops and public meetings.

The Final EIS is available online for viewing and download.

The Final EIS includes:

  • Analysis of the preferred alternative compared to the no-build and other Draft EIS alternatives
  • Environmental impacts of the alternatives and mitigation measures for adverse impacts
  • A financial analysis with several funding scenarios
  • Responses to more than 1,600 Draft EIS comments from agencies, tribes and the public

Each of the project's local sponsoring agencies endorsed publication of the final document, including WSDOT and ODOT. These agencies include TriMet, C-TRAN, Southwest Washington Regional Transportation Council and Metro.

A 30-day review period for the Final EIS occurred from Sept. 23-Oct. 24, 2011. During this time, the project hosted four informational drop-in sessions for the public to review the Final EIS and discuss the document with technical experts.
