Creating an effective defensible space involves establishing a series of management zones. Develop these zones around each building on your property, including detached garages, storage buildings, barns and other structures.
Zone 0 (The structure) the roof, eves or vents, siding, windows and foundation.
Zone 1 (0-5 feet from the home) is the area nearest the home and other structures.
Zone 2 (5-30 feet from the home) is the area transitioning away from the home where fuels should be reduced.
Zone 3 (30-100 feet from the home) is the area farthest from the home. It extends 100 feet from the home on relatively flat ground.
