HMM is a community-wide, exposure-based approach to reduce fire-spread hazards to each structure and parcel.
-
FIRST, Remove, Reduce, and Relocate parcel-level fuels,
THEN, assess for cost-effective home hardening.
-
A significant increase in structure ignition prevention is achieved by protecting structures against the complete range of potential exposures.
-
This necessitates that all structures are fully hardened for high ember exposures.
Three important considerations when assessing fire spread within and across parcels are:
- parcel boundaries typically limit the continuity of protection between parcels,
- linear features can carry fire very efficiently within and between parcels, and
- fuel agglomeration has significant impact on energy release and fire spread.
