How do you make a fire barrier around the house?

On level ground, leave a perimeter of grass and shrubbery clippings 30 feet . If your home is on a steep slope (20° or more), stretch the perimeter to 100 feet. Trim trees six to ten feet off the ground. Remove dead or dying trees from your property; use a chipper to remove brush piles (ideal fuel for fires)

Firebreaks are breaks or gaps created in vegetation that stop the movement of wildfire. Fuel breaks and undergrowth knockdown can control the rate of fire spread.
