(AP) — California water regulators, alarmed by slack conservation three years into a crippling drought, took the unprecedented step last summer of establishing statewide restrictions and gave communities a hammer to enforce them: a $500 fine for excessive watering of lawns, hosing down driveways and running decorative yard fountains with drinking water. Recognizing that hole in data collection, the board plans to start tracking how cities ensure compliance with water regulations. Representatives of water agencies say fines can be counterproductive to educating customers about conservation. Since Summer, Santa Maria residents used 34 gallons a day more than other Central Coast residents, but the city has only responded to 20 calls about water wasting and hasn't issued any penalties. Coachella Valley Water District Conservation Manager Dave Koller said his staff members have to go to great lengths to track down the wealthy out-of-state residents who keep vacation homes with water-guzzling landscapes. The Beaumont-Cherry Valley district in rural Riverside County imposed restrictions under state mandate, but General Manager Eric Fraser said an aggressive pursuit of water-wasters doesn't make sense for an agency that has enough water in local storage to supply customers for four years.
