LOS ANGELES, Calif. – Today, the Los Angeles County Board of Supervisors approved a motion authored by Board Chair and First District Supervisor, Hilda L. Solis, and coauthored by Supervisor Lindsey P. Horvath to adopt and implement the County’s Heat Action Plan, a blueprint that outlines the County’s response to rising temperatures and extreme heat events.
Extreme heat is among the biggest weather-related hazards contributing to more than 200 deaths annually in L.A. County. More frequent extreme-heat days – a byproduct of ongoing climate change – exacerbate health risks, economic burdens, and infrastructure strain, especially in historically underserved communities.
“The County’s Heat Action Plan is not just a blueprint – it’s a commitment to support Angelenos as we navigate a rising trend in extreme heat events,” said Board Chair Solis. “Now more than ever, the actions we take today to protect our residents will ensure we create cooler and healthier neighborhoods in the future, while advancing heat resilience.”
In response to this, the County’s Chief Sustainability Office (CSO) developed the County Heat Action Plan to help neighborhoods, infrastructure and ecosystems stay cool, with a focus on cooling outdoor space, heat-resilient indoor spaces, and public education on heat safety.
“The County Heat Action Plan is a call to action. Its success depends on County departments, unincorporated communities, cities, and regional and community stakeholders working together to advance heat resilience,” said Rita Kampalath, the County’s Chief Sustainability Officer. “I invite all of our partners to use the County Heat Action Plan as a shared blueprint for building a cooler, healthier, and more equitable Los Angeles County.”
“The County Heat Action Plan will protect residents—especially renters and families in hotter areas like the San Fernando Valley—who are already bearing the brunt of rising temperatures, limited shade, and inadequate home cooling,” said Supervisor Lindsey P. Horvath. “This plan builds on our first-in-the-nation tenant protections from extreme heat and prioritizes the physical and social infrastructure necessary to adapt to our changing climate.”
The approved motion moves forward with the adoption and implementation of the County Heat Action Plan, guiding County departments and 88 cities on heat-related actions and resources, in addition to serving as a model for local action. The motion also directs the CSO to align the County’s local, State, and Federal legislative agenda with the plan’s priorities, including support for funding and policies that safeguard vulnerable communities from extreme heat.
