Bushfire Hazard Assessment & Management Plan v2 NCES REF: J000542
Lot 9 on RP225312 — 100 Cooyar Street, Noosa Heads

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. al. 2017.

Table 1: Potential Bushfire Intensity classes

 

i. Very high 40,000+ kW/m
2b High : | 20,000 - 39,999 kW/m
3. Medium 4,000— 19,999 kW/m

 

 

 

3.4 Bushfire Hazard Sub-Units

A sub-unit level Local Hazard Area Map has been prepared; Plan No. BFO2 — 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 22.1, 29.2, and 34.5 are located within the northern, southern, and eastern extents of the
assessment area.

Note, Sub Unit 4 comprises VHC 39.2 — Low to moderate tree cover in built-up areas. VHC 39.2 is
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 4 was mapped as Low Potential Bushfire Intensity class on BFO2.

3.5 Overall Local Hazard Map

An overall Local Hazard Map has been prepared; Plan No. 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
northern, southern, and eastern extents of the assessment area with their associated Potential
Impact Buffer impacting the majority of the site precluding the central west site extent.

The Local Hazard Map presented in Plan No. 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.
