Plans for a new hotel wing with an additional 200 rooms were announced in April 2017. Hotel construction began in September 2015, and the six-story, 200-room hotel opened in November 2016. In January 2015, the tribe secured $450 million in financing for the resort, including up to $200 million to build a hotel. The tribe secured $825 million to fund the project, the greatest amount ever financed for an Indian casino. Construction work began the following June.

Ī tribal-state compact was reached in March 2012 after negotiations with Governor Jerry Brown, and was soon ratified by the California State Legislature. The land was not taken into trust until October 2010, after the lawsuit failed. The action was delayed, however, when a local group opposing the project, Stop the Casino 101, filed a lawsuit contesting the decision. The Bureau of Indian Affairs approved the tribe's application to take the land into trust, a key step towards approval of a casino, in May 2008. Station Casinos bought the Wilfred Avenue tract for the tribe for $76 million, and also bought 180 acres of the Stony Point land for $24 million, to use for environmental mitigation projects. The new site was said to be less environmentally sensitive, and more compliant with the county's land use plan, which had designated the Stony Point Road site for open space. The tribe announced in August 2005 that the planned site would move again, this time to a 90-acre site on Wilfred Avenue, closer to the city limits. A new site on 360 acres of land west of Rohnert Park, on Stony Point Road, was announced in August 2003, with strong support from city officials. The plan sparked widespread criticism about the potential effects on wetland restoration efforts and increased traffic on Highway 37, leading the tribe to consider other locations in Rohnert Park and Petaluma. The tribe announced plans in February 2003 for a casino to be built at a 1,700-acre site on Sears Point, near the shore of San Pablo Bay. In November 2016 it opened an adjacent hotel with 200 rooms. The casino has 3,000 slot machines, 144 table games, and a poker room. It is owned and operated by the Federated Indians of Graton Rancheria. Graton Resort & Casino is an Indian casino and hotel outside Rohnert Park, California, that opened on November 5, 2013.
