Meeting papers

Adjacent to the existing car parking area and tennis courts is a line of disturbed vegetation
containing a range of native canopy species with a low coverage of ground covers with areas
containing a range of exotic and native amenity shrubs.
The bushfire assessment found that the risk associated with bushfire was from outside the
proposed development area i.e. Girraween Nature Reserve to the north and east. Resort Drive
forms a natural firebreak that would be sufficient to buffer most ground fires, however a significant
bushfire involving Girraween Nature Reserve on a high fire danger day with an easterly wind has
the potential to cross Resort Drive and involve the vegetation within the subject site.
The report determined that a fire within the site, particularly involving the vegetation associated
with the northern and eastern boundary would be of low intensity and burn up the dominant slope
away from any of the existing infrastructure.
In response to the bushfire risk, the proposal has included a range of mitigation measures along
the northern and eastern boundary to reduce risk to people and property. This includes separation
distance from mapped hazardous vegetation that achieves a radiant heat flux of less than
29kW/m2. To achieve this outcome the development footprint along the northern and north-eastern
boundary must meet a minimum separation of 15.7 metres.
The below image, which is taken from the applicant’s BHA, indicates that Pavilion 5 achieves
24.465 metres and 21.965 metres at the ends of the building closest to the hazardous vegetation
which will achieve a radiant heat flux with 19-29kW/m2.




                        Figure 11: Proximity of pavilion 5 to hazardous vegetation

The building is separated from the northern hazardous vegetation via the proposed overflow
carpark which is approximately 35 metres in length. 35 metres will achieve a radiant heat flux of
12.5kW/m2.
The BHA has provided a range of comments and recommendations to reduce risk on the
infrastructure and users within the site. These include:
•     Hazardous vegetation retained in proximity to the development is separated by Resort
      Drive, tennis courts and auxiliary parking to provide a buffer between hazardous vegetation
      and the proposed structures.
•     A minimum setback between future habitable structures and the edge of potential
      hazardous vegetation is 15.7 metres which achieves a radiant heat flux of less than
      29kW/m2 and as such an acceptable level of risk achieved as defined under the State
      Planning Policy, Natural Hazards, Risk and resilience.
•     Landscaping within the site to utilise species considered to be less flammable where
      rehabilitation is required to match the existing 12.2.5 Regional Ecosystem.
