VHC 43.6 is attributed a potential combined surface fuel load of Ot/ha and total fuel load of Ot/ha,
and is classified as Prone Type 3 (QFES, 2019). Plate 12 depicts typical conditions within VHC 43.6.

3.3 Potential Bushfire Intensity classes

Table 1 details the Potential Bushfire Intensity classes and their corresponding potential fire-line
intensity (KW/m) values as prescribed within Leonard et. a/. 2017.

3.4 Bushfire Hazard Sub-Units

A sub-unit level Local Hazard Area Map has been prepared; Plan BF02 — Sub-Units and identifies
the site scale Potential Bushfire Intensity classes across the site. The sub-unit level Local Hazard
Area Map identifies that High and Medium Potential Bushfire Intensity Areas associated with the
VHC 8.1, VHC 9.1, VHC 36.1 are located within the north-western, southern, and eastern extents of
the assessment area.

Note, Sub Unit's 3-5 comprise VHC 2.1 — Complex to simple, semi-deciduous mesophyll to notophyll
vine forest (mature fuel loads assumed), VHC 39.2 — Low to moderate tree cover in built-up areas,
or VHC 43.6 Water bodies or very low vegetation cover. VHC 2.1, VHC 39.2, and VHC 40.4 are
classified as Prone Type 3 — Low hazard. As per Section 7.5.2, 7.6 & Figure 14 of Bushfire Resilient
Communities 2019, Prone Type 3 VHC’s are not considered bushfire prone VHC’s. Therefore, Sub
Unit's 3-5 were mapped as Low Potential Bushfire Intensity classes on Plan BFO2.

3.5 Overall Local Hazard Map

An overall Local Hazard Map has been prepared; Plan BF03 — Local Hazard Map and identifies the
Potential Bushfire Intensity classes across the site as well as associated 100m wide Potential Impact
Buffer areas. High and Medium Potential Bushfire Intensity Areas are located within the north-
western, southern, and eastern extents of the assessment area with their associated 100m wide
Potential Impact Buffer extending towards the central site extent. The eastern limit of the proposed
development is captured within the Potential Impact Buffer.

The Local Hazard Map presented in Plan BFO3 is to supersede 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.
