Shiloh Resort & Casino - Project Status

Overview

The Shiloh Resort & Casinois a proposed $600 million tribal gaming and resort project planned by the Koi Nation of Northern California on a 68-acre site near Windsor in Sonoma County. The project originally called for a large casino, hotel, and entertainment complex intended to establish a permanent economic base for the tribe.

On January 13, 2025, the U.S. Department of the Interior approved the Koi Nation's application to place the Shiloh property into federal trust for gaming purposes. However, that approval was overturned in federal court on September 3, 2025, leaving the project without the legal foundation required to move forward.

Federal court ruling

A U.S. District Court ruling on September 3, 2025, vacated the land-into-trust approval for the Shiloh site and remanded the matter back to the Department of the Interior for further proceedings. The court identified several key problems with the original approval:

• Unauthorized approval: The decision was signed by a Bureau of Indian Affairs director rather than the Senate-confirmed Secretary of the Interior.
• Insufficient consultation: The Department did not adequately consult with the Federated Indians of Graton Rancheria, whose ancestral territory includes the Windsor area.
• Historical ties analysis: The court found that the record did not sufficiently support the Koi Nation's historical connection to the Shiloh parcel under the Indian Gaming Regulatory Act's restored-lands provision.

By vacating the decision, the court removed the land from trust status and required Interior to redo its analysis, including consultation and historical review, if the agency chooses to pursue the project again.

• Land status: The Shiloh property is not in federal trust following the court's 2025 ruling.
• Construction: No construction has occurred. The tribe previously committed not to build during litigation, and the vacated approval prevents development.
• Appeal: The Koi Nation and federal defendants filed an appeal in 2025, but the court declined to keep the land in trust during the appeal.
• Interior review: The Department of the Interior has not issued a new decision or restarted a full public review process.
• Timeline: There is no published schedule for renewed federal action or for any potential opening date.
• Opposition: The project continues to face opposition from local governments, the State of California, and the Federated Indians of Graton Rancheria.

Taken together, these factors place the Shiloh Resort & Casinoin legal and regulatory limbo, with the project effectively frozen and its long-term viability uncertain.

The Shiloh Casino & Resort project remains in the federal environmental review phase. The Draft EIS has been completed, and the Bureau of Indian Affairs is preparing the Final EIS. No construction has begun, and no ground-disturbing activity is permitted until the federal trust decision is finalized. The Koi Nation continues to refine project plans and engage with local stakeholders while awaiting the next stage of the approval process.
