Wildfire doesn’t understand property lines.
As you create your own personal wildfire mitigation plan, please take into account the following home ignition zones. A free assessment of your property is available through the DNRC (linked below).
Immediate Zone (0–5 feet from the home)
- This is the most vulnerable area. Remove all tree limbs and vegetation within this zone. No tree branches should overhang or touch the house, and any limbs that extend into this space should be cut back. Also:
- Eliminate shrubs and other flammable plants completely.
- Replace mulch with non-combustible material like rock or concrete.
- Ensure no limbs come near vents, eaves, or decks.
Intermediate Zone (5–30 feet)
- Here, prune and thin trees to minimize ladder fuels that can allow a surface fire to climb into the canopy. Recommendations include:
- Trim lower branches 6 to 10 feet from the ground.
- Maintain at least 10 feet of clearance between the roof and overhanging limbs.
- Space remaining trees and shrubs to prevent fire from moving between them.
- Clear vegetation around fences, sheds, and outdoor structures.
Extended Zone (30–100 feet)
- Tree thinning in this zone helps break up continuous fuel beds. Key actions include:
- Maintain at least 12 feet of space between tree canopies to disrupt crown fire spread.
- Remove small conifers growing beneath mature trees to prevent fire from laddering up.
- Eliminate leaf and needle debris regularly to keep the area clear.
- Trim vegetation back from driveways and access routes to support emergency access.
