Thurston County approves resolution supporting Chehalis Basin flood strategy review, pending legal review

The Thurston County Board of County Commissioners on Dec. 3 voted to sign a revised resolution expressing support for the Chehalis Basin Flood Authority's ongoing strategy work — including flood mitigation and aquatic species restoration — and instructed staff to send the resolution to county legal for review.

The chair (name not stated) provided historical context for the resolution, saying the basinwide strategy emerged after the 2007 floods and that legislative funding has supported both habitat work and flood projects. He emphasized the county has historically "supported the process" without taking a firm position on any specific flood-retention structure, and said his edited resolution removes language that could be read as endorsing a dam or other particular design.

Scott Venture, staff to the Chehalis River Basin Flood Authority, described the authority's work: "We are collectively in a process called the Chehalis flood strategy process... we are doing projects on the ground, pumps, treatment plant protection, flood warning system, habitat. Those things are all happening well." Venture said sustained county participation and resolutions of support help secure continued legislative funding for analysis and projects.

The board moved and voted to sign the revised resolution; the chair and commissioners noted the document will go to county legal for review before finalization. No specific project approval or funding action was taken at the Dec. 3 work session.

Why it matters: The resolution signals Thurston County's willingness to support continued analysis and funding for basinwide flood and habitat work. Commissioners emphasized remaining neutral on specific structural solutions until additional analysis and tribal input are considered.

The resolution passed with the board's approval pending legal review.
