Appendix F Bushfire Management Plan

The radiant heat flux values for Methods 1 and 2 are compared as Bushfire Attack Levels (BALs) in Table 2 and
Figure 9. The predicted fireline intensity for the adjacent forest assessed is in the “Medium” range, as indicated
in State and Coluncil hazard mapping (Figure 4).




Figure 9. Radiant Heat Flux Predicted by Methods 1 and 2.

Application of Method 2 under AS3959-2018 demonstrates similar setbacks to be required as Method 1.

A minimum setback of 13m will be provided to the closest wall, supporting column or post of any future
dwelling. Within this space, Class 10a structures may be built, however if they are within 6m of the dwelling
their construction shall be in accordance with AS3959-2018, Table 2 and Figure 9 above.

The significance of the radiant heat flux levels discussed is shown below in Table 3.
