Overview

• 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.
