Defensible Space

Creating a defensible space for your property is crucial in the fight to protect your home! The desired fire-safe condition is a maintained landscape; it is NOT bare ground. Check out the below points and get started!

  • Address numbers – minimum 4 inches high with 1/2 inch stroke and shall contrast with the background or be reflective.

Defensible Space Activities are conducted by Home owner or contractor. Eligible expenses for approved grant activities occur during the 2018 Grant Program work period January 2 through July 20, 2018.

Defensible Space

State and Local Fire Codes identify two defensible space treatment zones for fuel modification:

  • Zone 1: 0 – 50 feet from any habitable structure.This area requires the greatest reduction of flammable vegetation and consists of low growing fire-resistant plants.
    • Remove dead vegetation and dead trees, mow, remove weeds, prune lower limbs.
    • Trim tree limbs at least 10 feet from chimneys, remove dead branches hanging over buildings.
    • Reduce the amount of fuel around the structures by separating the space between fuels, and or reshaping the retained fuels by trimming.
    • Replace flammable vegetation with low growing less combustible plants.
  • Zone 2: 50 – 100 feet from habitable structure.
    • In this area thinning brush/plants to cover 50% of ground. Natural plants can remain. Spacing between plants improves the chance of stopping a wildfire – create horizontal and vertical spacing between the plants.
    • Trim low hanging branches; this eliminates a vertical fire ladder of vegetation.
    • Remove all dead and dying vegetation.

    Defensible Space includes:

    • Stack firewood at least 30 feet away from structures.
    • Maintain a 13 foot 6 inch vertical clearance over all roads and driveways for emergency vehicle access.
    • Remove combustible vegetation to a height of six inches within ten feet of ground mounted solar panels.
    • Remove combustible vegetation to a height of six inches within 15 feet of propane tank.
    • Remove garbage, refuse, trash, cuttings.
    • Remove all combustible vegetation within 20 feet along both sides of driveways and roadways that bound your property.

The 3-R’s of Defensible Space

  • Remove: Dead and dying grass, weeds, shrubs, and trees. Separate the fuels.
  • Reduce: the density of vegetation – prune, mow and thin.
  • Replace: flammable vegetation with less combustible plants.
