LOS ANGELES — California on Wednesday suspended its mandatory statewide 25 percent reduction in urban water use, telling local communities to set their own conservation standards after a relatively wet winter and a year of enormous savings in urban water use.
The new rules are a sharp change in policy for a state struggling to manage one of the worst droughts in its history. They came after a winter in which El Niño storms fell short of what meteorologists projected — particularly in the southern part of the state — but still partly filled parched reservoirs in Northern California and, more critically, partly replenished the mountain snowpacks that provide water into the spring and summer.
And Californians, responding to an executive order issued in April last year by Gov. Jerry Brown, reduced their use of potable urban water by 24 percent compared with 2013 levels. Officials said they were hopeful that reduction would prove permanent because of changes in water use such as replacing lawns with droughttolerant shrubs.
The rules do not apply to agriculture, which is covered by different regulations and makes up the bulk of water use in the state. Cuts in supply based on seniority were imposed in the last year. Some of them have been rolled back already as water has become more available.
The rules, adopted by the State Water Resources Control Board, are likely to mean a huge rollback — and in some places, an elimination — of water reduction mandates that have forced people, businesses and governments to curb watering of gardens and lawns, take shorter showers and flush toilets less frequently.
State officials said that the drought, already in its fifth year, was not over and that Californians had to adapt to permanently more arid times because of climate change. Even as officials eased up on the regulations, the state made permanent prohibitions against washing down sidewalks and driveways, using a hose without a shutoff valve to wash cars and banning the use of water on road medians.
Still, officials said that conditions had improved enough that the drastic measures that Mr. Brown announced were no longer needed.
“We are still in a drought, but we are no longer in the-worst-snow-pack-in-500-years drought,” said Felicia Marcus, the head of the state water board. “We had thought we are heading toward a cliff. We were worried we were in our own Australian millennial drought. We wanted to make sure people didn’t keep pouring water on their lawns with wild abandon.”
Many of the 411 water agencies across the state, even as they complied with the mandatory cutback, had complained that the statewide requirement failed to take into account water supply conditions, which vary widely from region to region. And some, such as in Beverly Hills, with its estates surrounded by sweeps of lawns and gardens, resisted at first, but eventually complied.
Under the new rules, which take effect on June 1, communities would set reduction guidelines based on their own projection of water supplies, assuming that the next three years here continue to be uncommonly dry. The state would review the projections and could impose restrictions on communities it determines were being unrealistic.
Max Gomberg, the climate and conservation manager for the board, said it would review the order again in January and could return to mandatory statewide reductions if communities revert to waterwasting habits or if next year were dry again. Some meteorologists are predicting a weather pattern next year known as La Niña, the opposite of an El Niño, meaning that rainfall levels are significantly below normal.Read more...
