Caesars Breaks Ground on New ‘Republic’ Casino Resort in California

Caesars Entertainment is expanding its presence in the California casino market through redevelopment of the longtime River Rock Casino in Sonoma County.

In partnership with the Dry Creek Rancheria Band of Pomo Indians, the gaming giant broke ground last week on Caesars Republic Sonoma County – a major overhaul that will transform the two-decade-old tribal property into a full-scale resort under the Caesars Republic brand.

The deal marks the first time Caesars has extended its Republic brand – a typically non-gaming, urban hotel concept – into a tribal casino resort setting.

Scheduled to open in mid-2027, the reimagined property will include a 125-room hotel, expanded casino floor, new dining outlets and a wellness spa. The resort casino will feature more than 1,000 slot machines and 28 table games.

Casino is a Milestone for the Tribe and Caesars

The project represents both a milestone for the tribe and a strategic foothold in California for Caesars, which operates more than 50 casino properties globally but will not own or operate the Sonoma casino. The gaming license and operations remain under the tribe’s control, consistent with federal Indian gaming laws.

“For over 20 years, River Rock Casino has been a pillar in Sonoma County,” said Dry Creek Rancheria Chair Chris Wright. “This next chapter brings new energy and national recognition to what our Tribe has built.”

Caesars Republic Sonoma County is located off U.S. Highway 101 and sits above the Alexander Valley Vineyards, providing breathtaking views of both the vineyards and the Russian River.

“This is a true partnership,” said Caesars Entertainment CEO Tom Reeg at the groundbreaking. “We’re proud to bring the strength of the Caesars brand to Northern California, working in lockstep with the Tribe to elevate this property into something extraordinary.”
