Rohnert Park officials are scrambling to prepare for a great unknown that has been years in arriving — what will happen when a 24-hour, 3,000-slot-machine casino opens on the west edge of the city?

‘We have no idea what the impacts will be,’ Vice Mayor Joe Callinan said Tuesday as the council reviewed the report of a city task force that is trying to answer that question.

After a decade of controversy, environmental studies, lawsuits and bureaucracy, the $800 million Graton Resort & Casino is expected to open Nov. 1.

An unprecedented tsunami of development along Highway 101 in Sonoma County is putting thousands of people to work and pumping nearly $2 billion into the economy.

Up and down the spine of Sonoma County, more than a dozen big-budget projects are underway, creating or expanding centers for the arts, shopping opportunities, health care facilities, business offices, hotels, restaurants and a casino resort.

From his property just west of Rohnert Park, Danny Nakash has watched with anticipation the rapid rise of the casino being built by the Federated Indians of Graton Rancheria. It is a sight he long waited for because it signals what he hopes will be a boon to his business, Raz Taxi.

Talks are under way about how three fire agencies should divide a one-time $1.5 million payment that the Federated Indians of Graton Rancheria is giving to Sonoma County to address impacts from the casino being built outside Rohnert Park.

Rohnert Park and the Federated Indians of Graton Rancheria have agreed to a new revenue-sharing deal worth $40 million more than one they signed in 2003. The agreement is intended to more fully address the impacts of the casino the tribe is now building.

The future shape of gambling in Sonoma County gained greater detail Monday as Station Casinos released the first official drawings of the enormous Indian casino under construction outside Rohnert Park.
