9.5.22 Bushfire Hazard Assessment Management Plan v2 - 60 Glenridge Drive COOROIBAH

Bushfire Hazard Assessment & Management Plan v2                                 NCES REF: J001001
Lot 47 on RP860577 – 60 Glenridge Drive, Cooroibah



6    AUSTRALIAN STANDARD 3959:2018 CONSTRUCTION OF BUILDINGS IN
     BUSHFIRE PRONE AREAS (AS 3959:2018) SETBACKS

In general, the far northern and southern portions of the site are mapped within the Bushfire
Hazard Overlay in the Noosa Plan 2020 (refer Plate 12) and SPP Bushfire Hazard Overlay
Map (refer Plate 1).




                                        Plate 12 – Asset Protection Zones

Building works within land which has been designated under a power of legislation as being
subject, or likely to be subject, to bushfires triggers building design assessment under AS
3959:2018 (NCC 2019).
The Standard provides minimum construction requirements for new habitable dwellings and
habitable building alterations in designated Bushfire Prone Areas. The construction
requirements are intended to improve the performance of buildings subjected to burning
debris, radiant heat or flame contact. Building works in Designated Bushfire Prone Areas must
be built to the Bushfire Attack Level (BAL) construction standard relevant to the building site
as identified by the AS 3959:2018 methodology.
Based on the setbacks provided, all future Class 1 buildings are anticipated to achieve a BAL
29 construction standard or lower. A specific BAL assessment will be required once building
plans have been progressed given the BAL relies on an accurate understanding of the final
footprint of the building within the individual building envelopes and is required to be assessed
against the active iteration of the Standard at the time of assessment.
In this instance it is noted that several of the proposed building envelopes are located outside
of the mapped extent of both the Noosa Council and State Planning Policy designated Bushfire
Prone Areas. Proposed building works located outside of these mapped areas are not required
to be built to satisfy AS 3959. It is noted that mapping would be expected to be expanded
across the majority of the site in the future once the extent of proposed revegetation works
matures.
