Upscale Beverly Hills is among four California cities where water utilities have been fined for not forcing residents to conserve enough water during California's unrelenting four-year drought, officials said on Friday.

The wealthy Los Angeles area municipality was fined $61,000 on Thursday, making it the only community not located in a desert singled out for penalties, the California State Water Resources Board said.

"Some urban water suppliers simply have not met the requirements laid before them," said Cris Carrigan, director of the water board's Office of Enforcement. "For these four suppliers, it's been too little too late."
