A SOLUTION THOUSANDS OF MILES LONG
An extensive network of pipes and channels throughout LA County help to solve our current stormwater challenges by reducing the risk of flood when it rains, capturing stormwater, and cleaning it before it enters our waterways.
Operated by the LA County of Public Works since 1985, the Los Angeles Flood Control District (District) manages over 2,800 miles of underground storm drains, 14 major dams, and 500 miles of open channel. Within the county, many cities help manage local storm drain systems, capture and clean water in spreading grounds, and spearhead other water quality projects. Additionally, The U.S. Army Corps of Engineers operates five dams in LA County. Together, these efforts not only enhance the beauty and cleanliness of our rivers, streams, and oceans, but also protect our health and safety.
