How to Comment on the 2022 Supplemental Environmental Assessment

On November 15, 2022, the Oregon Department of Transportation (ODOT) released a Supplemental Environmental Assessment (EA) for the I-5 Rose Quarter Improvement Project for public review and comment in accordance with the National Environmental Policy Act (NEPA). 

The official comment period is open from November 15, 2022 - January 4, 2023.

You can help us respond to questions and concerns by being as specific as possible with your comments. This means including page numbers or citing specific parts of the EA document in your comment. Additional explanations, facts and references are also helpful, when appropriate. Specific interests, thoughts and concerns are more effective than broad statements and more likely to be used to improve the final documents and analyses.

As a reminder, commenting on the Supplemental EA is not a vote on the project but an opportunity to provide decision-makers your input about the environmental analysis of the preferred design alternative.

There are several ways to submit a comment regarding the Supplemental EA's findings, and all comments received are viewed equally:

  • Online via our web comment form found below
  • Send an email with "Supplemental EA public comment period" in the subject line to:
  • Call and leave a recorded voicemail at (503) 470-3127
  • Provide your verbal comments at the virtual public hearing on Tuesday, December 14, 2022, from 5 to 7:30 p.m.
  • Send a written comment to this address:

    Project Manager
    c/o I-5 Rose Quarter Improvement Project

Your feedback on the Supplemental EA is an important part of the environmental review process.
