Political leaders from the California governor to a U.S. senator to the Windsor Town Council long ago went on record in their opposition to a resort-casino proposed by the Koi Nation on a 68-acre plot of lightly developed land in the Shiloh neighborhood, just outside Windsor city limits.

That project could allow the Koi to build one of the Bay Area’s largest gambling operations.

Now, two local officials have written their concerns into federal court filings.

Lynda Hopkins, representing the Sonoma County Board of Supervisors, and Jon Davis, the Windsor town manager, a month ago filed declarations opposing the Koi Nation’s attempt to dismiss a lawsuit brought by the Federated Indians of Graton Rancheria against the U.S. Department of the Interior and its newish secretary, Doug Burgum.

That suit seeks to reverse Interior’s approval of the Koi project, granted in the final days of the Biden administration.

Both declarations include multiple attached exhibits that represent a catalog of previous public comments by the Board of Supervisors and Windsor Town Council, respectively.

“The County’s voluminous comments include numerous objections from County engineers, planners, hydrogeologists, biologists, and planners that should have given the Bureau of Indian Affairs — or really, any reasonable person — pause before approving the project that is at issue in this litigation,” Hopkins, wrote to the U.S. District Court’s Northern District of California, which is overseeing the case, on behalf of the board she chairs.

“The project is in an area of the County that does not allow commercial development, and that has been subject to devastating wildfires.”

Hopkins’ attachments included a board resolution passed in April 2022, and the supervisors’ public comments to the Bureau of Indian Affairs during three separate phases of environmental review, as well as their comments on the Koi’s fee-to-trust application.

Davis offered even more exhibits: a resolution passed by the Windsor Town Council advocating an agricultural land use designation for the Shiloh Road property (also in April 2022), five separate comment letters to the bureau and another letter sent to then-Secretary of the Interior Deb Haaland in 2024.

“The Final Environmental Impact Statement (for the Koi project) is inadequate and it is of vital public interest for these issues to be adjudicated,” Davis wrote in his declaration.
