I-Zone Tutorial - Wildfire Basics
"Homes in Urban Neighborhoods" are typically closer together, fenced and landscaped, on city water with hydrants and may even have several swimming pools in the immediate area. These neighborhoods are at risk from wildfire because of the wind blown embers (fire brands) generated from a fire front, burning trees and landscaping, fences, or burning houses.
As fire approaches, fire crews will patrol neighborhoods looking for spot fires and extinguishing them to save the neighborhood. Hopefully the hydrants still have water pressure and the engines can refill and keep patrolling. Water systems are typically designed to fight one fire in any given area at a time. A single fire engine pulling water and fighting a house fire can reduce the hydrant pressure in an entire neighborhood to zero! This eliminates the ability of other engines to refill.
It also stops the water supply to your house!
These homes almost never catch fire from the actual wildland fire. Most catch fire when embers are blown into their attics through inadequate ventilation vents, land in gutters filled with flammable material, or find a hole or crack someplace to lodge and (with the wind blowing on it) manage to catch your house on fire. Unfortunately, if a fire manages to start in an attic or under a roof tile the house will almost always be lost!
There are just not enough resources or water available to enter the house and find the seat of the fire to extinguish it. The wind that caused this problem in the first place has a devastating affect on burning structures. All the firefighters can do is try to cool the burning house a bit in order to save the other houses in the neighborhood.
