Table 1: Potential Bushfire Intensity classes




The subunit level Local Hazard Area Map is presented as Figure 2 and identifies the site is affected
by High and Very High Potential Bushfire Intensity areas.
Several subunits were patch and corridor filtered out of Figure 2 due to their limited patch size (i.e.,
each individual unit is less than 0.5ha and/or less than 50m width). These small subunits have been
merged with the dominant adjoining Vegetation Hazard Class.
Narrow corridors are less likely to ignite due to their disconnection with fuels that can carry a running
fire front. If the corridor is ignited by either a point source or line ignition, these areas will limit the
width of the fire head and hence fire line intensity. The combination of these likelihood and intensity
estimates indicate it is unlikely that a fire line intensity of 4000kW/m would be achieved and can be
considered a low hazard for the purpose of land use planning to mitigate bushfire risks (Leonard et.
al. 2017).
The site scale overall Local Hazard Map is presented in Figure 3 and identifies the following Potential
Bushfire Intensity Areas within the assessment area:

    •    Very High Potential Bushfire Intensity Area;
    •    High Potential Bushfire Intensity Area; and
    •    Potential Impact Buffer.

The proposed building envelopes have been located in the Potential Impact Buffer Areas.

The site scale Local Hazard Map presented in Figure 3 shall be viewed as superseding the SPP
broadscale mapping attributed to the site and should be used to guide the formulation of appropriate
site-based bushfire management measures for the proposal.
