5    BUSHFIRE IMPACT REDUCTION MEASURES

5.1 General
The following section describes bushfire impact reduction measures to be incorporated into
the proposed development to reduce the risk of bushfire impacts to people and property.
Implementation of the identified measures is not implied nor intended to advocate that building
occupants remain on the site during a bushfire event, nor that people and property will be
protected from bushfire impacts. The measures are intended to reduce the potential severity
of bushfire impact to the development and not prevent bushfire impact. The bushfire mitigation
measures have been derived from:
    •    Department of State Development, Manufacturing, Infrastructure and Planning’s State
         Planning Policy – State interest guidance material – Natural hazards, risk and
         resilience – Bushfire (December 2019) (referenced herein as SPP (Bushfire) 2019);
         and
    •    Queensland Fire and Emergency Services. (2019). Planning for Bushfire Resilient
         Communities.

5.2 Asset Protection Zones
5.2.1    General
Asset Protection Zones (APZ) provide a defensive tool to assist in the reduction of potential
bushfire impact to people and property situated in bushfire prone areas. For illustrative
purposes, Plate 11 depicts the concept of an APZ surrounding a dwelling in a bushfire prone
areas.




                                        Plate 11 – Asset Protection Zones

The development has been confirmed to be located within a bushfire hazard area hence
provision of adequate separation between the building envelopes nominated immediately
flanking the hazardous vegetation is required to provide a reasonable level of safety to site
occupants and emergency services staff.
The configuration of APZ’s is typically determined based on the results of the site-specific
hazard assessment including risk of bushfire impact, flame length analysis, applicable

Development supports, and does not hinder, disaster management response or recovery

To ensure emergency access and operational space for firefighters the subdivision layout
results in lots that are sited so that they are separated from the closest edge to the adjacent
