Arizona's Growing Wildfire Threat
Wildfires in Arizona have increased in both frequency and intensity. Pima County has seen significant fire events threatening homes in Oro Valley, Catalina, Catalina Foothills, and the Tucson Mountains. The combination ofprolonged drought, invasive grasses, record temperatures, and expanding development has created conditions where virtually every foothill property faces wildfire risk.
What Is Defensible Space?
Defensible space is the managed area around a structure that slows wildfire spread and provides a safe zone for firefighters. Homes with properly maintained defensible space are 2-3 times more likely to survive a wildfire. Fire departments may not defend homes that lack it.
Zone-by-Zone Guide
Zone 1: Ember-Resistant Zone (0-5 feet)
Remove all vegetation. Use gravel or stone next to the foundation. Clear gutters. Screen vents with 1/8-inch metal mesh.
Zone 2: Lean, Clean, and Green Zone (5-30 feet)
Create spacing between plants. Limb up trees 6-10 feet. Ensure 10-foot gaps between tree crowns. Mow grass to 4 inches.
Zone 3: Reduced Fuel Zone (30-100 feet)
Thin trees to 40-60% canopy coverage. Remove dead trees and excessive deadwood. Break up continuous brush.

Frequently Asked Questions
Does insurance cover defensible space creation?
Most policies don't directly pay for it, but many insurers offer premium discounts (up to 15%) for Firewise communities or documented defensible space. Some now REQUIRE it in high-risk areas.
How often should I maintain my defensible space?
Annually before fire season, ideally by May. High-risk properties may need twice-yearly maintenance.
Will defensible space make my yard look bare?
Not at all. Fire-smart landscaping can be beautiful. The key is strategic spacing, proper species selection, and maintaining green, hydrated plants in Zone 2.
