Defensible Space & Fire Mitigation
Defensible space and wildfire tree mitigation for Malibu hillside properties
CAL FIRE-aligned tree spacing, lower-branch clearance, and selective thinning that reduce wildfire risk without turning your hillside into a bare lot. Arborist-led, slope-aware, and built for ongoing upkeep.
Why it matters
Why defensible space matters
Ember protection, structure survivability, firefighter access, insurance and compliance — and landscape preservation, not bare-lot clearing.
Ember protection
Reduce the fuels embers ignite — deadwood, palm fronds, low branches.
Structure survivability
Create the space that lets a structure survive an advancing fire.
Firefighter access
Give firefighters room to work and defend the property.
Treatments
Tree & vegetation treatments offered
-
Lower-branch clearance
Break ladder fuels by removing low branches that carry ground fire into the canopy.
-
Tree spacing
Create horizontal gaps between trees so fire cannot easily jump crown to crown.
-
Canopy thinning
Thin overcrowded canopies to reduce fuel load and improve air movement.
-
Dead & dying removal
Remove dead, dying, and diseased trees that are prime fuel.
-
Palm & deadwood
Remove palm fronds and deadwood that embers ignite easily.
-
Selective limbing
Limb up trees while preserving shade, views, and the landscape character.
Zones
Defensible-space zones explained
The three zones around a structure, with the clearance approach for each.
-
0–5 ft
Zone 0
Hardscape, minimal plants, nothing combustible against the structure.
-
5–30 ft
Zone 1
Trees thinned and pruned, low branches cleared, ground fuels reduced.
-
30–100 ft
Zone 2
Reduced fuel density, wider tree spacing, managed vegetation.
Assessment
