Landscape Architecture for Fire Protection
Creating Defensive Space Without Sacrificing Beauty
The most sophisticated fire-resistant construction can be compromised by inappropriate landscaping choices. Creating an effective defensive space requires understanding both fire behavior and landscape design principles to develop solutions that are both beautiful and protective. This guide summarizes how to create landscapes that enhance property value while providing crucial fire protection through strategic plant selection, hardscape integration, and maintenance planning.
Zone-Based Design Strategy
Zone 1 (0-5 feet from structure)
Non-combustible materials only:
Concrete or stone patios
Gravel or rock mulch
Limited potted plants in non-combustible containers
No vegetation against structures
Hardscape specifications:
Minimum 18" depth for gravel areas
4" concrete thickness minimum
1/4" maximum joint width
Maintenance requirements:
Monthly debris removal
Quarterly inspection
Annual hardscape evaluation
Zone 2 (5-30 feet)
Limited, strategic planting:
Maximum 30% coverage
10' minimum spacing between specimens
No trees within 15' of structures
Approved plant species:
Succulents: Aloe, Sedum, Ice Plant
Ground covers: Creeping Thyme, Woolly Yarrow
Shrubs: Rockrose, Lavender, Sage
Cost: $15-25 per square foot installed
Zone 3 (30-100 feet)
Reduced fuel landscaping:
40% maximum vegetation coverage
Strategic tree placement
Fire breaks using hardscape
Maintenance protocols:
Quarterly pruning
Monthly weed control
Annual dead material removal
Water Features as Fire Breaks
Strategic placement:
Property boundaries
Adjacent to structures
Along access routes
Design specifications:
Minimum 6' width
18" minimum depth
Non-combustible surrounds
Cost: $200-300 per linear foot
