The HMM considers that homes within a community are interconnected via combustibles, and therefore their survival during a wildfire depends on unified community hardening. The goal of this method is to provide community leaders with guidance to work with homeowners to protect their properties and the entire community.
The exposure/distance hardening strategy proposed in the HMM offers a path forward that creates discontinuities for fire exposures and selectively hardens structures where clear benefits to ignition resistance can be achieved at a reasonable cost.
