Whittier Narrows Dam manages flood risk for about 1.2 million people from Pico Rivera to Long Beach. In 2016, the U.S. Army Corps of Engineers  classified it as DSAC 1 — 'critically near failure or extreme high incremental risk.' The Corps found that the dam's foundation was at risk of erosion, and a major storm could trigger its gates to open prematurely, which could 'release more than 20 times what the downstream channel can safely contain.
