The Lower Green River is at risk of severe flooding. Floods are dangerous and destructive. They threaten our safety, block the movement of people and goods, harm the environment, and cause significant damage.

The King County Flood Control District (District) is developing a Flood Hazard Management Plan to guide future flood reduction investments in the Lower Green River Valley, and we want to hear from you!

The District is conducting a study called a Programmatic Environmental Impact Statement (PEIS). This study will analyze ways to provide flood protection and meet other important multiple benefits including equity, habitat and salmon recovery, community, agriculture, development, water quality, and recreation. The scoping comment period for the PEIS is now underway. A previous public scoping period occurred in 2018-2019. The District revised alternatives to address issues raised during that scoping period. The new alternatives are the subject of this new scoping period.

The District wants to know what you think of these alternatives and how flooding in the Lower Green River Valley would impact you and your community. Your input will shape flood protection planning in Auburn, Kent, Renton, Tukwila, and unincorporated King County.

There are no right or wrong comments. We're interested in hearing your feedback on what should be studied in the PEIS such as:

  • Flood risk in the corridor
  • Equity and social justice
  • Environmental justice
  • Multiple benefits
  • Engineering and design
  • Programs and policies
  • Monitoring and mitigation
  • Planning and land use
  • Coordination
  • And more!

We will host two virtual public meetings on January 6, 2022. You can learn more and provide comment at
