California, Inundated
It doesn’t take much rain for road intersections to wind up underwater, says Brett Sanders, a professor of civil and environmental engineering at the University of California, Irvine. He has worked to develop another effort to educate residents: a hyperlocal forecasting system to inform them of the risk that their neighborhoods — or even streets — face from a coming storm. … “This event is a bit of a wake-up call,” he said.
