ACTC’s strategy:

Utilize Fire Hazard Severity Zone map developed by CAL FIRE Utilize FEMA’s THIRA/SPR (Threat and Hazard Identification and Risk Assessment / Stakeholder Preparedness Review) process: Develop community/ neighborhood level fire hazard assessment and evacuation route development

• 1. Understand extreme

weather-related events that will occur with greater frequency and intensity in future years

• 2. Conduct vulnerability

assessments

• 3. Develop method to

prioritize projects that recognize climate change concerns and limited financial resources Caltrans D10 Climate Change Vulnerability Report objectives:
