Oro Valley FAQ
Do I need to clear brush around my Oro Valley home?
If your property is in a WUI zone along the Catalina foothills, you must maintain defensible space by clearing dead vegetation within 30 feet of structures and reducing vegetation density out to 100 feet. Contact the Golder Ranch Fire District for specific requirements.
What is buffelgrass and why is it a fire concern?
Buffelgrass is an invasive grass species that creates continuous fire fuel in the Sonoran Desert where fires were historically rare. It is highly flammable when dry and is a major wildfire hazard in the Catalina foothills. Property owners should remove it as part of defensible space maintenance.
Tucson FAQ
Do I have to clear brush at my Tucson home?
If you are in a wildland-urban interface area near Saguaro National Park or the foothills, yes. Maintain 30 feet of defensible space and reduced fuel within 100 feet, including active buffelgrass removal.
Can I cut down a saguaro for fire safety?
No. Saguaros are protected under Arizona Native Plant Law. You may prune damaged arms but not remove healthy saguaros without ADA permit. Manage fuel by clearing grasses and deadwood instead.
