County Heat Action Plan
The Los Angeles County Heat Action Plan (CHAP) is an all-of government agenda for ensuring communities and ecosystems can thrive in the face of rising temperatures and more extreme heat. Developed through a multi-layered engagement process launched in summer 2024, the CHAP guides regionwide action, investment, and collaboration for heat resilience. The CHAP lays out three primary goals:
- GOAL 1: Cool Outdoor Spaces
- GOAL 2: Create Heat-Resilient Indoor Spaces
- GOAL 3: Expand Heat Safety Communications and Programs
Implementation of the plan will reduce heat exposure, support everyday safety, and build long-term resilience — especially in communities facing the greatest risks. The plan is available below.
