Regional Action Roadmap for Extreme Heat and Wildfire Smoke From the South-Central Puget Sound Climate Resilient Communities Accelerator

The Regional Action Roadmap for Extreme Heat and Wildfire Smoke is a collaborative framework to help communities, businesses, and governments in Washington’s South-Central Puget Sound region build resilience to worsening climate hazards. The Roadmap is the outcome of the first year of C2ES’s Climate Resilient Communities Accelerator— a two-year program that activates public and private partners around shared hazards and high-impact resilience strategies—and serves as the foundation for coordinated implementation in year two. It synthesizes six key action areas—spanning community-led disaster preparedness, energy resilience, catalytic policy, business continuity, nature-based solutions, and built environment upgrades—that enable regional leaders to coordinate cross-sector strategies and advance a shared vision of a safer, healthier, more equitable future. The Roadmap was informed by insights from and codeveloped during the 2025 South-Central Puget Sound Accelerator convenings, which engaged more than 90 participants across 72 organizations spanning government, Tribes, nonprofits, academia, and the private sector.
