Review our report on options to help the Chehalis River 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.

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

Draft study ready for review

As part of a community effort to restore the basin and put it on a path to recovery, we have completed a draft environmental report, officially called a programmatic Environmental Impact Statement.

Our review evaluates four basin-wide options that were developed and submitted to Ecology by the community to address flood damage and aquatic species habitat. We've evaluated the impacts, both positive and negative, to people and the environment. Now we need your input.

Send us your feedback

We’ve worked hard to give these invested stakeholders a fair assessment of how different solutions will affect their community’s environmental planning. Now that we've completed the assessment and analysis of four basin-wide options, we're making the draft environmental report available for public review.

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.
