The Strategy

Sunset over the river

The Chehalis Basin Strategy is an ambitious collection of potential actions to address the challenges of extreme flooding and degraded river habitat. The State of Washington and local leaders are working to develop the Strategy to both improve river habitat and reduce flood damage. It will be a basin-wide strategy that includes near-term and long-term actions, as well as small and large scale projects. The long-term goal of the Strategy is to make the basin a safer place for families and communities impacted by flooding, and to improve and restore aquatic species habitat now and for future generations.

The Chehalis Basin Strategy includes two overarching types of actions, habitat restoration and flood damage reduction. There are many actions within each of these types. Nothing is decided at this point for the long-term strategy – these are just the actions being considered. Two major goals are to restore over 200-500 miles of aquatic species habitat and reduce the damage from severe flooding.

Summary of actions being considered in the Chehalis Basin Strategy to reduce flood damage and restore habitat:

Restore over 200-500 miles of riverside habitat:

  • Improve river habitat
  • Restore riparian areas
  • Remove fish passage barriers
  • Reconnect the floodplain
  • Restore wetlands
  • Protect priority habitat
Local-scale actions:

  • Floodproofing / Farm pads
  • Local flood projects
  • Land use management 
  • Integrated early flood warning systems
Large-scale actions:

  • I-5 walls?
  • Levees at Centralia Airport and Aberdeen/Hoquiam?
  • Restorative flood protection?
  • Flood retention facility (dam)?
