In just over a decade, Indian casinos have shot from backcountry slot machine emporiums to enormous gambling meccas, an escalation completely at odds with original promises. The latest proof of this failed pledge is an $800 million operation in Rohnert Park due to open [on November 5]. The Graton Resort & Casino will be a major economic force in Sonoma County, employing some 2,000 employees and promising $20 million in annual local payments. Instead of smoke-filled gambling halls, it will offer high-end restaurants, ornate chandeliers and skylights in a main building surrounded by nearly 6,000 parking slots. But the huge operation is a reminder of how far things have strayed from the promises made to California voters in 2000. A state ballot measure argued that impoverished tribes living in remote corners of California had few if any alternatives for economic development. Now gambling is Vegas-scale, and casino tribes are vying against each other for prime spots. The Rohnert Park casino will jump in front of another operation 30 miles to the north in Geyserville, and that worried tribe has bought land in Petaluma for a possible operation that will be closer to Bay Area gamblers. One tribe's win is another's loss. California taxpayers have a stake too. Sold on an ever-increasing slice of revenues, a string of state governors have approved more than 60 casinos. Gov. Jerry Brown, who approved the Graton operation, signed two other casino deals in the Central Valley sought by tribes who wanted more lucrative spots.
