Dynamic Planning + Science assisted the City of Napa in updating its Local Hazard Mitigation Plan (HMP) in compliance with the Disaster Mitigation Act of 2000. The 2021 plan builds upon the 2015 HMP and provides a comprehensive roadmap for reducing the city’s vulnerability to natural hazards such as floods, wildfires, earthquakes, and climate change impacts. The HMP identifies risks to people, property, and infrastructure, and presents actionable strategies to break the cycle of disaster damage and reconstruction through pre-disaster planning.
The planning process engaged city officials, local agencies, community stakeholders, and residents through a robust outreach program that included a public survey and web-based engagement. The updated HMP incorporates new risk data and technologies, provides an extensive vulnerability assessment, and presents over 40 targeted mitigation actions aligned with the City’s goals to become a safer and more resilient community.
The plan ensures the City of Napa remains eligible for FEMA’s Hazard Mitigation Assistance programs and serves as a critical resource for integrating hazard mitigation into broader planning and capital improvement efforts.
- Multi-Hazard Risk Assessment: Analyzed dam failure, drought, earthquake, extreme weather, flood, wildfire, pandemic disease, and climate change using FEMA Hazus software and GIS-based spatial overlays.
- New Risk Data and Tools: Integrated advanced data, web-based risk mapping, and FEMA’s Hazus software to estimate potential losses and prioritize hazards based on population, infrastructure, and economic exposure.
- Robust Community Engagement: Included an online public survey, stakeholder interviews, and planning committee input to inform problem statements and shape actionable mitigation strategies.
- Comprehensive Mitigation Action Plan Identified and prioritized more than 40 mitigation actions for hazards including
- Integrated Climate and Resilience Planning: Addressed long-term vulnerabilities related to climate change, including sea level rise, increased wildfire risk, and heat extremes, with adaptation-focused actions and risk modeling.
- FEMA Approval and City Adoption: Approved by FEMA and Cal OES in 2022 and formally adopted by the Napa City Council to ensure continued eligibility for federal hazard mitigation grant programs.
