As temperatures in Southern California reach triple digits this week, Rep. George Whitesides, D-Agua Dulce, is helping to lead a series of bills aimed at addressing the growing threat of extreme heat.

Together, these bills will bring critical infrastructure improvements to at-risk communities, assist the federal government in responding to heatwaves, and coordinate strategies to create long-term solutions.

“With temperatures rising in California and across the country, it’s more important than ever to take action to protect our communities,” said Rep. Whitesides. “This slate of bills will provide important resources to keep families safe, reduce heat risks, and strengthen our response to rising temperatures.”

The following three bills as part of Rep. Whitesides’ efforts to combat extreme heat:

The Excess Urban Heat Mitigation Act 

-This bill supports projects that improve infrastructure, green spaces, and innovative technologies to cool at-risk cities.
