Southeast Area Transportation Solutions Coalition (SEATS)

SEATS is a transportation and economic development coalition led by the cities of Covington, Maple Valley, and Black Diamond, with participation from the cities of Auburn and Enumclaw, King County, Port of Seattle, Sound Transit, Puget Sound Regional Council, Washing-ton State Department of Transportation, and BNSF Railway. While we consist primarily of government agencies today, we hope to expand our reach to the private sector in the future. View the SEATS priorities brochure by clicking here.
