- Hazards Mitigation Plan
VISION: All sectors of the community work together to create a disaster resilient region.
The current plan was approved by FEMA on February 15, 2024, and is effective through February 14, 2029.
Living in the Puget Sound Region entails inherent risks, with the hazard mitigation plan serving as a crucial tool to address geological threats like earthquakes, tsunamis, landslides, and volcanic eruptions. Climate changes bring increased flooding and wildfire risks. Vulnerable populations, such as the elderly and low-income households, need equitable hazard mitigation strategies to reduce their risks. The Emergency Management Council of Thurston County has led the region's plan updates since 2000. Adopted in 2003 and regularly updated every five years, the recently updated 4th Edition Hazards Mitigation Plan for the Thurston Region ensures ongoing and coordinated disaster resilience efforts within our communities.

Mitigation Planning Strengthens Region’s Resiliency
The 4th Edition Hazards Mitigation Plan for the Thurston Region outlines a multijurisdictional strategy to reduce the risks of the most destructive natural hazards such as floods, earthquakes, and wildfires that threaten communities in Thurston County. The plan’s goals, policies, and actions, if implemented, will minimize losses, and protect the people and community assets from future disasters.
The plan’s regional mitigation strategy includes 12 actions to improve multi-agency coordination, build mitigation capabilities, and strengthen resiliency across Thurston County. In addition, each plan participant produced an annex that prioritizes actions to minimize losses within their jurisdiction.
