What is an ignition zone and what do I do about it?
The Rancho del Sol geographic area is located within a State Responsibility Area (SRA), which means that Cal Fire is the primary emergency response organization responsible for fire suppression and prevention. (Use the State Responsibility Area Viewer to check out your property's hazard risk).
Here is a whole updated (2024) website page on Fire Hazard Severity Zones.
Because we are located in an SRA, homeowners are required by several California laws to create and maintain 100 feet (or to the property line) of defensible space. This is further broken down into 3 Ignition Zones where homes are vulnerable to three ignition sources: embers, surface fires and crown fires.
IMMEDIATE ZONE: 0-5 feet from any existing structure - create an "ember-resistant zone", including under and around decks; this requires stringent fuel reduction.
INTERMEDIATE ZONE: 5 -30 feet out create a "Lean, Clean & Green" zone immediately surrounding your home
EXTENDED ZONE: 30 -100 feet (or up to the property line, whichever is closer) create a "Reduce Fuel Zone"
Overall, to increase the chance your home will survive a wildfire the emphasis is on
- limiting the amount of flammable vegetation
- choosing ignition resistant building materials and construction techniques,
- and conducting regular exterior maintenance in the home ignition zones
