“It angers me because people aren’t looking at the overall picture,” Butler said. “What are we supposed to do, just have dirt around our house on four acres?”

Rancho Santa Fe residents are hardly the only Californians facing a water crackdown. On Friday, the state said it would impose sharp cutbacks on senior water rights dating back to the Gold Rush for the first time in four decades, a move that primarily hits farmers. And starting this month, all of California’s 400-plus water districts are under orders to reduce flow by at least 8 percent from 2013 levels.

Top water users such as Rancho Santa Fe are required to cut consumption by 36 percent. Other areas in the 36-percent crosshairs include much of the Central Valley, a farming region that runs up the middle of the state, and Orange County, a ritzy Republican stronghold between San Diego and Los Angeles.

“I call it the war on suburbia,” said Brett Barbre, who lives in the Orange County community of Yorba City, another exceptionally wealthy Zip code.
