For Immediate Release

County of Sonoma seeking public input regarding Graton Rancheria Resort & Casino expansion plans

Santa Rosa, CA | April 15, 2022

The Federated Indians of Graton Rancheria have issued a Notice of Preparation of a Tribal Environmental Impact Report for the proposed Graton Resort & Casino expansion project. The County of Sonoma is seeking the public’s input to inform its own comments on the Notice of Preparation, which are due on May 4. The county will forward all public comments received with the official county response.

The county anticipates that a draft Tribal Environmental Impact Report will be released on or after May 5, approximately 30 days from the Notice of Preparation. The county is committed to participating in the environmental review process and will provide opportunities for public engagement on this issue.

The Graton Resort & Casino includes the existing casino and a 200-room hotel and banquet facility, which were the subject of an exhaustive environmental review approved by federal agencies in 2010. The existing resort, which opened in November 2013, includes gaming, dining, a hotel, and spa facilities and associated parking. In 2016, the tribe proposed and issued a Tribal Environmental Impact Report for the addition of 200 hotel rooms and other amenities, however for various reasons that project was never constructed. The tribe now proposes to expand the resort with the construction of additional facilities, including an approximately 144,000-square-foot casino floor expansion, a new five-level, 221-room hotel wing, a new five-level parking structure, a 3,500-seat theater, an expanded swimming pool area, a rooftop restaurant, an additional water tank and central plant.

Comments on this Notice of Preparation can be emailed to the county at or sent directly to the Federated Indians of Graton Rancheria per the Notice of Preparation at:
