What Is Defensible Space and How Do You Create It in Shasta County?

Defensible space is one of the best tools for wildfire preparedness. It can help slow the spread of wildfire, improve firefighter access to your property, and increase the chance your home can be protected during a wildfire.

So What Is Defensible Space? 

Defensible space is the area around your home where vegetation is managed to slow the spread of wildfire and reduce risk to structures. In Shasta County, this typically means maintaining a 30- to 100-foot buffer around your home.

Why It Matters

Shasta County has established new defensible space requirements for all properties, strengthening community wildfire prevention efforts. 

How Do You Create Defensible
Space Around Your Home?

Think of it as basic yardwork with serious consequences.

Clean roofs & gutters

Mow to 4 inches or less

Trim dead or overhanging branches

Cut stumps to 8 inches or less

Maintain 10 feet of clearance around generators & fuel storage

What Are Ladder Fuels & Why Do They Matter for Wildfire Safety?

Ladder fuels are vegetation that allows fire to climb from the ground into tree canopies, increasing wildfire intensity and spread.  Proper spacing between plants and trees helps stop fire from moving vertically and horizontally across your property. 

Prevent fire from climbing.

  • Keep tree branches at least 6 feet off the ground.
  • Trim your trees so that branches are at least 10 feet from your roof.
  • If you have a shrub under a tree, multiply the shrub’s height by three and make that the space between the top of the shrub and the branches of the tree.

Flat or moderately-sloped land

  • Separate shrubs by a distance of 2X their width
  • Keep tree canopies 10 feet apart

     

More steeply-sloped land

  • Separate shrubs by a distance of 6X their width
  • Keep tree canopies 30 feet apart

Defensible Space Zones
in Shasta County

Defensible space in Shasta County focuses on managing the area around your home in two key distances: the first 30 feet, and the space beyond that up to 100 feet when needed.

The goal is to reduce anything that could easily ignite and allow fire to reach your home.

  • Remove dead leaves, debris, and dry vegetation
  • Keep roofs and gutters clear
  • Maintain low, well-spaced plants
  • Trim trees and branches away from structures

This area helps reduce wildfire intensity and slow its spread before it reaches your home.

  • Reduce overall vegetation density
  • Space trees and shrubs to prevent fire from traveling
  • Remove dead or dying vegetation
  • Maintain separation between plant groupings
