Partner Agencies Contributing to Arizona’s Heat Resilience

In 2024, Governor Katie Hobbs asked her Office of Resiliency and the Interagency Resiliency Forum to work with Arizona State agencies to create the first Arizona’s Extreme Heat Preparedness Plan. The plan presents a coordinated effort, emphasizing collaboration among state agencies to better prepare for extreme heat and enhance community resilience. The following agencies play key roles in this initiative through strategic planning, community outreach, funding, and other essential measures.
