San Diego County is a tough place not to run into the interface. The geography has little flat plain. I wish the graphic (or accompanying story) would have discussed the effect of the building code and zoning(?) changes that require fire resistant materials for the homes and defensible space for the communities. The LA Times had an article discussing Stevenson Ranch in Santa Clarita(?), and how the code changes made a big difference in terms of the number of home threatened in that community versus others.
It sends me through the roof, though, when news articles tell of firefighters spending their time having move woodpiles away from structures, as well as trimming trees and having to <em>create</em> defensible space once a home is in a threatened area. I get why seniors and disabled folk might not be able to do the home maintenance, but others? The firefighters should be spending their time fighting the fire, not doing the maintenance the homeowner was supposed to do.
