LOS ANGELES — The Los Angeles River roared to life this week as a series of powerful storms moved through the Southland. In Long Beach, 3 feet of water shut down the 710 Freeway in both directions, while flooding in the San Fernando Valley forced the closure of the Sepulveda Basin.
It was by all accounts a washout, but despite heaps of water pouring into the area, drought-weary Los Angeles won't be able to save even half of it. The region's system of engineered waterways is designed to whisk L.A.'s stormwater out to sea — a strategy intended to reduce flooding that nonetheless sacrifices countless precious gallons.
Voters in 2018 approved Measure W, which is aimed at improving L.A.'s aging stormwater capture system. Officials are making progress, but experts say there's a long way to go. Of an estimated 5 billion to 10 billion gallons pouring into the Los Angeles Basin from current storms, only about 20% will be captured by the county.
