A behind-the-scenes battle to divert L.A.'s storm water from going to waste

Joe Mozingo, Contact Reporter, LA Times

The storm had gathered power for days as it crossed the Northern Pacific, and now its outer band was uppercutting the coast.

By the time Eric Batman arrived at work at 7 Monday morning, a hard west wind was driving rain and hail sideways against windows. Thunder reverberated across the L.A. Basin.

Batman reveled in El Niño's long-overdue rumbling.

His job, as senior civil engineer for the county Department of Public Works, is to keep as much rain as possible from escaping to the ocean.

He wished this storm would slow down a bit. Let the mountains wring more of that water out. Make it more of a challenge.

Even at its current clip, the clouds would drop hundreds of millions of gallons on Southern California, and he needed to make sure the system was ready.

On the second floor of the department's headquarters in Alhambra, he checked in with the "storm boss," the on-duty engineer in charge of monitoring flow rates throughout the 3,300-mile network of storm drains, channels, debris basins, dams, spreading grounds - everything humans have built over the last century to control the water racing from the high San Gabriels to the sea.

"Where are we open?" Batman asked. "How much are we taking in?"

The storm boss told Batman that he had inflated one of the seven rubber dams along the lower San Gabriel River.

This move would divert the flow into a spreading ground in Pico Rivera - 90 acres of porous soil that can suck up 75 cubic feet of water every second to be stored in the aquifer below.

But the water wasn't there yet. The San Gabriel takes its time.

With age, the county's two big rivers - sisters born of the same weather systems and topography - have grown distinct in appearance and temperament.

The L.A. River is a fast and moody Type A, and it's had a lot of work done.

EPA full steam with 'Waters' protection rule, but trouble ahead

The Obama administration on Wednesday launched a sweeping measure to protect the nation’s waterways and wetlands — an initiative that faces a fierce counterattack from powerhouse industries like agriculture, oil and home-building.

On its face, the final “Waters of the United States” rule is largely a technical document, defining which rivers, streams, lakes and marshes fall under the jurisdiction of the EPA and the Army Corps of Engineers. But the industries and their allies in Congress condemn it as a massive power grab by Washington, saying it will give bureaucrats carte blanche to swoop in and penalize landowners every time a cow walks through a ditch. And it comes amid years of complaints from Republicans about President Barack Obama’s regulatory agenda, which has encompassed everything from power plants and health insurers to Internet providers and for-profit colleges.
