Programmatic EIS

Final Programmatic Environmental Impact Statement

The Washington State Department of Ecology prepared a State Environmental Policy Act (SEPA) Programmatic Environmental Impact Statement (PEIS) to evaluate a suite of actions to reduce flood damage and restore aquatic species habitat.

More than 500 comments were received during the Draft PEIS public comment period, and responses to the comments received are included in the Final EIS. The Final EIS has been published as an addendum to the Draft PEIS, and both can be found below.
