Bushfire Hazard Assessment & Management Plan v4 - 7 Triller Court, Pomona

Bushfire Hazard Assessment & Management Plan v4                                    NCES REF: J000841
Lot 4 on SP320405 – 7 Triller Court, Pomona



within Lots 4-6 and the northerly adjacent hazardous vegetation, and a minimum 26m wide
APZ is recommended to be applied between the building envelopes within Lots 4-6 and the
southerly adjacent hazardous vegetation to satisfy the SPP Bushfire 2019 Assessment
Benchmark 4 <29 kW/m² criteria.
Lot 7
A minimum 24m wide APZ is recommended to be applied between the Lot 7 building envelope
and the northerly adjacent mapped KHA (sub unit 4) and a minimum 26m wide APZ is
recommended to be applied between the Lot 7 building envelope and the southerly adjacent
hazardous vegetation to satisfy the SPP Bushfire 2019 Assessment Benchmark 4 <29 kW/m²
criteria.
A minimum 18m wide APZ is recommended to be applied between the Lot 7 building envelope
and the westerly adjacent hazardous vegetation to satisfy the SPP Bushfire 2019 Assessment
Benchmark 4 <29 kW/m² criteria.
All recommended APZ’s are to be maintained in accordance with the landscape criteria
specified in Section 5.6 for the life of the development or until such time as an alternative
setback can be justified (i.e. where assessment methodologies change).

5.3 Water Supply
The availability of a reliable water supply for firefighting purposes is a vital tool in the defence
of bushfire impact. Reticulated water supply is currently available to the site and will be
provided to the proposed lots. To ensure suitable water supply design for emergency purposes
it is recommended the water supply satisfy the QLD QFES Fire Hydrant and Vehicle Access
Guidelines for Residential Commercial and Industrial Lots 03/2019 ( refer Appendix 2).
No further specific recommendations concerning water supply are deemed necessary to
comply with the SPP or the NSC Bushfire Hazard Overlay Code.

5.4 Fire Breaks
The provision of fire breaks and fire trails within a site located in a bushfire prone area offers
an important bushfire defence measure to assist in reducing the risk and severity of bushfire
ingress onto and through a site. A significant risk of fire impact has been identified from the
west and north of the site.
The head of the existing sealed bitumen road leading from Reserve Street offers a 24m wide
trafficable firebreak to the north-east of Lot 4 and the hazardous vegetation to the north to
north-east hence offers a desirable fire break in this location.
The proposed access easement serving Lots 4-7 offers a minimum 10m wide fire break
equivalent between the northern boundaries of Lots 4-6 and the hazardous vegetation to the
north. Additional open space low threat conditions are expected to be present in the front of
Lots 4-6 post development hence the equivalent of 24m wide fire break will be available
between Lots 4-6 and the hazardous vegetation to the north.
The existing clearing on Lot 7 provides a trafficable firebreak to protect Lots 4-6 from fire
ingress from the west.
No specific firebreak is considered necessary within proposed Lot 7 as the expansive APZ
about the large building envelope provides easily trafficable access between the building
envelope and the adjacent vegetation to the north, south and west.
The northern and western perimeters of the development footprint are therefore expected to
be readily trafficable during a bushfire emergency hence the design is supported in this regard.

5.5 Vehicular Access
Development in bushfire prone areas should be serviced by safe access/exit points for both
occupants and emergency services personnel. The lots are to be accessed via a shared 90m
long access easement which connects to the terminus of Triller Court. Triller Court is
approximately 260m long and connects to Reserve Street to the east. Vehicular access is
