Now, in a sign of growing water anxieties, the Skechers warehouse and six other large projects in western Riverside County are on hold until March or later because the local water agency could not promise to deliver water to serve them.
"Just looking at the raw numbers, we kept coming up short," said David J. Slawson, president of the board of directors of the Perris-based Eastern Municipal Water District, one of the largest districts in the state.
Slawson explains that his own livelihood as a land surveyor depends on growth, that no one on the board wants to hobble the economy. Still, he said, the restriction is "something we feel is necessary until we have some better numbers and we see some action statewide."
He says he's surprised that other water districts have not paused to review their own supplies.
This winter is posing the first significant test of two little-known state laws passed in 2001 that link large development to the availability of water.
The Eastern district may be the first in the region to cite water as the reason for delaying approval of a large project because of the laws.
Developers and water officials worry that more agencies may do the same, further weakening a building market already crippled by the sub-prime mortgage crisis. Although Inland Empire business leaders hope Eastern will ease its restrictions as early as March, the district is offering no guarantees.
"No water. No construction. It's a bad combination," said Borre Winckel, executive director of the Riverside County Building Industry Assn., which has seen a dramatic decrease in requests for building permits.
But state Sen. Sheila Kuehl (D-Santa Monica), sponsor of one of the two laws, says it is working the way it should, by requiring cities to be realistic about how ambitious developments can strain water supplies to the limit.
The twin laws require local water agencies statewide to assess the needs of large projects and assure that water supplies are there for both existing and new customers for the next 20 years. The Kuehl law focuses on residential growth of 500 units or more, while a related one sponsored by a former state senator, now Rep. Jim Costa (D-Fresno), requires supply studies for all large projects.
Since then, Eastern water district officials approved 82 studies, called water supply assessments, for new projects in the fast-growing region.
Each time, they looked at whether the projects would strain water supplies. Each time, they found that the water was there. That changed last year, amid what some are calling "the perfect drought," a confluence of natural problems sharply decreasing water deliveries to the area: a record-low snowpack in the Sierra Nevada, an eight-year drought in the Colorado River Basin, record-dry weather at home.
The final blow came in late summer with a federal court decision protecting the endangered Delta smelt by limiting water deliveries from the Sacramento-San Joaquin Bay Delta, linchpin of the state Water Project that distributes water statewide. The federal order, made final in December, will reduce deliveries to Southern California by an estimated 22% to 30%, state officials say.
"What triggered things was the cutback on the state Water Project," said Peter Odencrans, spokesman for Eastern. "That made us think that until we work things out and get some security, we'd better be a little more cautious, and make sure that the data we come up with we do stand behind 100%."
The Eastern Municipal Water District distributes water to a 550-square-mile area from Moreno Valley to Temecula and Hemet nearly to Lake Elsinore. The area's population is now 660,000, but that is expected to soar eventually to 1.5 million, district officials said.
"We estimate that there may be requests for 120,000 new homes in our service area by 2030," Odencrans said. The current construction slowdown may offer some time for district water officials to study projected growth statistics and finish a projected $1 billion in capital improvements planned within five years.
