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 aquatic species habitat. The Office of Chehalis Basin and Chehalis Basin Board was created in 2017 to aggressively pursue implementation of an integrated Strategy for long-term flood damage reduction and aquatic species restoration in the Chehalis River Basin. 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, aquatic species 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.

Below is a summary of actions being considered in the Chehalis Basin Strategy:

Restore over 200-500 miles of riverside habitat by:

  • Restoring and improving river habitat
  • Removing barriers and improving fish passage
  • Reconnecting the floodplain
Local-scale actions:

  • Installing farm pads
  • Protecting critical infrastructure like roads.
  • Improving land use and floodplain management
  • Helping basin residents understand flood insurance 
  • Taking integrated early actions
Large-scale actions:

  • Proposed Chehalis River Basin Flood Damage Reduction Project
  • Comprehensive Community Flood Assistance and Resilience program
  • Aberdeen Hoquiam North Shore levee
  • Projects to protect regional transportation corridors
