In the midst of unyielding downpours, Los Angeles' innovative "sponge" infrastructure successfully captured 8.6 billion gallons of water, providing enough resources to support more than 100,000 households for an entire year.
- LA's transformation into a sponge city includes permeable surfaces and spreading grounds to absorb stormwater.
- The city captured 8.6 billion gallons of water during a recent atmospheric river event, enough for over 100,000 households for a year.
- This approach is part of a broader strategy to manage water resources sustainably and mitigate urban flooding.
"The more trees, the more shade, the less heat island effect."

Why this matters:
LA's success in managing extreme weather through sponge city infrastructure is a model for sustainable urban planning. It demonstrates how cities can adapt to climate change, reduce flooding, and efficiently utilize natural resources.
Capturing and reusing urban storm water could be a boon for water-stressed cities—if we can find a way to clean it up.
