Wildfire Mitigation
Comprehensive wildfire prevention and protection strategies
Wildfire mitigation in the wildland-urban interface
Wildfires are driven by weather, fuels, and topography. In the wildland-urban interface (WUI), embers and surface fire can ignite homes long before a flame front arrives, so homes, landscaping, and community plans all matter.
Think in zones: hardening the structure, managing fuels in the yard, and coordinating with neighbors reduces ember entry and ignition risk across the WUI.
Embers and home ignition
Most WUI home losses are linked to embers entering vents, gaps, or accumulated debris. Hardening the roof, screening vents, and managing combustible materials near the structure are high-leverage actions.
High-leverage home hardening
- Class A roof where required and practical; clear debris from gutters
- Ember-resistant vent screens and sealed gaps at siding and eaves
- Move firewood, mulch, and combustible storage away from walls and decks
Defensible space
Create and maintain zones around structures: reduce ladder fuels, separate shrubs, and keep wood and mulch away from siding and decks. Work with neighbors: ember showers and wind do not respect property lines.
Defensible space reminders
- Break up continuous vegetation that carries fire to the roof line
- Keep lawns and beds maintained; replace highly flammable plants where practical
- Coordinate fence lines and access with neighbors and public safety
Codes and standards
Building codes and local ordinances increasingly reference WUI construction and vegetation. Pair code requirements with public education so residents understand why setbacks matter.

Lessons from recent events
Post-disaster assessments (after the Marshall Fire and Maui wildfires) reinforced the importance of ember-resistant construction, evacuation routes, and clear communication. For deeper case narratives, see the Lessons Learned After Disasters collection.
