Reducing the Vulnerability of Buildings to Wildfire

0723 wildfires

What can be done to improve the chances that a home will survive wildfire? The good news is that research has demonstrated that by careful attention to the selection, location and maintenance of vegetation and other combustibles on the property (i.e., the defensible space on the property), implementing retrofits to “harden” the home, and implementing an ongoing maintenance program, it is possible to substantially improve the odds that a home will survive a future wildfire. These actions do not have to be costly, but they do require an understanding of the three types of exposures a home will experience when threatened by a wildfire.
