Evacuation Needs Assessment and Communication Strategies Study

Plan Framework

The Tuolumne County Evacuation Needs Assessment and Communication Strategies study is structured around three components:

  1. Potential Wildfire Risk - Identifies relative wildfire risk across Tuolumne County.

  2. Roadway Evacuation Needs Assessment – Describes potential limits to efficient evacuation based on modeled evacuation scenarios and identifies potential strategies for increasing the resiliency of egress routes.

  3. Communication Strategies – Identifies potential barriers to effective communication in preparation for and during an evacuation and recommends strategies for improving communication.

The Tuolumne County Evacuation Needs Assessment and Communication Strategies study identifies locations and communities at higher risk from wildfire and strategies to improve evacuation roadway capacity and communication to improve the County’s wildfire resiliency and preparedness.

The study furthers the understanding of wildfire risk based on historic data to inform strategies or approaches for future evacuations and identifies opportunities for evacuation-related transportation improvements for the Tuolumne County Transportation Council Regional Transportation Plan. The study does not identify evacuation routes or zones and is not an evacuation plan.
