L.A. County Captures Billions of Gallons in Stormwater Amid Atmospheric River Event

Efforts to enhance stormwater capture face challenges as extreme weather events become more common.

Los Angeles County captured 2.7 billion gallons of stormwater during the recent atmospheric river event, providing enough water for 65,600 residents for a year.
The L.A. River, designed for both flood control and water capture, faces challenges in maximizing stormwater retention amid increasing atmospheric river events.
Voters approved Measure W in 2018, allocating $280 million annually to stormwater projects, aiming to enhance L.A.'s water self-sufficiency and environmental safety.
Despite efforts, up to 80% of stormwater from recent storms was lost to the ocean, highlighting the need for improved infrastructure and green space to capture and utilize more rainwater.
Experts emphasize the urgency of addressing climate change and infrastructure degradation to better manage extreme weather events and safeguard water resources.
