The Sonoma County Board of Supervisors unanimously passed a resolution opposing the Koi Nation’s proposed casino and resort outside Windsor while discounting the tribe’s historical ties to the county.

The 5-0 vote came without any discussion beyond a quick comment from Supervisor James Gore, the board chair, who represents much of northern Sonoma County, including the land off Shiloh Road, where the Koi Nation plans to build its planned $600 million project.
