VIDEO: Finding solutions for the Chehalis basin

Oct. 24 UPDATE: We have decided to extend the public comment period for the Chehalis Basin Strategy environmental review after receiving five requests for an extension. The new closing date for the public comment period is Nov. 14, 2016

The Chehalis River Basin is at a turning point. In recent years, the basin has experienced extreme and frequent flooding, and it may experience larger floods more often in the future. Habitat for aquatic species is significantly degraded and, if action is not taken, is expected to decline further. We're working with the community to address these issues.

We are currently taking comments on our environmental review of solutions proposed for the basin. Learn more in this video, and join us at public hearings to share your feedback.

With a new environmental report out for public review, now is the time for you to get involved and engage on potential ways to restore aquatic habitat and reduce flooding throughout the Chehalis River Basin in southwest Washington.

Submit comments online now.

Comments now being accepted on environmental review

We have completed a draft environmental report, officially called a programmatic Environmental Impact Statement, as part of a community effort to restore the basin and put it on a path to recovery. The environmental review evaluates four basin-wide options that were developed and submitted to Ecology by the community to address these problems.

SEPA: Washington's environmental protection law

The State Environmental Policy Act (often called SEPA) gives a formal process to identify and assess possible environmental effects of a proposal before deciding how to proceed.
