The River Rock Entertainment Authority, operator of the River Rock Casino in Sonoma County, California, US, plans to build a destination resort on its Rancheria in Alexander Valley.

The new site is set to replace the current River Rock Casino, which will remain open during the construction period.

The $300m (£149m, 221m euro), 600,000sq ft resort will include a casino, 260 guest rooms, luxury suites, meeting rooms, an indoor swimming pool and restaurants.

The resort is being designed to resemble a Tuscan village, with courtyards, gardens, and buildings of varying heights.

Harvey Hopkins, chair of the Dry Creek Rancheria Band of Pomo Indians, said: “This resort will be a unique economic development opportunity to help our Tribe and our members, an unmatched destination resort experience to please our visitors, and a spectacular addition to benefit our neighbors in the Alexander Valley.”

The Tribe also plans to invest approximately US$76m (£38m, 56m euro) in infrastructure improvements to support the new facilities.
