Shorelines Master Program

Notice of Intent to Adopt Amendments, 30-day Comment and Joint Public Hearing for the Periodic Update to the Southeast Washington Coalition Shoreline Master Program


Shoreline protection is a certain key for long-term prosperity of our rivers and water systems in Columbia County. Our Shorelines protection act seeks to preserve hundreds of miles of valuable Shorelines throughout Columbia County.

Shorelines Update: 2023

 The next Shorelines Master Program update is due by June 30, 2023. The Cities of Dayton and Asotin have joined the original jurisdictions in the Southeast Washington Coalition which now consists of Columbia, Garfield, and Asotin Counties, the Cities of Clarkston, Asotin, and Dayton, and the Town of Starbuck. The jurisdictions have pooled funds of $302,400, awarded by the Department of Ecology for the required periodic review. 

Anchor QEA has been selected as the update consultant. Opportunities for public engagement will take place throughout the review process. A website has been developed to share updates, public meetings, and input opportunities. Please visit regularly to stay in the loop:  SE Washington Coalition Shoreline Master Program

Shorelines through the Years

In 1975, Columbia County adopted the first Shorelines Master Plan to protect our water resources. Until now, no changes have been made to our original Shorelines Master Program.
