The Flamesol Method 2 Minimum Distance calculator has been used to calculate the minimum
separation distance required between the development and bushfire-prone vegetation for each BAL
level. These results are provided in Appendix 1 and Figure 7 and summarised in Table 5.
Table 5: Determination of Bushfire Attack Level (BAL) minimum separation distances for bushfire-prone
vegetation.

PO7 of the Noosa Plan 2020 specifies that building envelopes on lots greater than 2500m2 are to be
separated from hazardous vegetation such that they achieve a radiant heat flux of 29 kW/m2 (BAL-29).
To achieve this outcome, the proposed habitable dwelling will need to be sited at least 39.9m from
unmanaged vegetation to the south/south-west and 36.7m from unmanaged vegetation to the east.
