“The flow of water was ferocious - some 65,000 cubic feet per second at the terminus of the L.A. River's flood control system. That's like 65,000 basketballs going by, every second, that are filled with water and weigh 62 pounds apiece,” said Los Angeles County public works director Mark Pestrella.
“As climate change brings more extreme weather - drought followed by deluges - Southern California will have to grapple with keeping flood defenses strong while dealing with some of the ecological, sociological and environmental damage the concrete system has caused.”
