Bushfire Report


4.6    Building Envelope and Asset Protection Zone
An Asset Protection Zone (APZ) will need to be established and maintained on the
subject site to ensure adequate separation from hazardous vegetation. This
designed APZ will have a radius of 30 m around the proposed building(s) as
minimum, consisting of a 10 m for the Inner Protection Area and a further 20 m for
the Outer Protection Area.

Figure 4-2 and Figure 4-3 illustrate the minimum APZ requirements. All distance
measurements for the APZ should be taken as horizontal distances. Management
strategies within the APZ will ensure that vegetation or other structures proposed do
not increase the overall potential fuel load. The Bushfire Management Plan will detail
these requirements comprehensively.

In the remaining areas on the subject site, the client should continue to maintain the
current vegetation management practices. Unmanaged vegetation will increase the
bushfire risk.

It is critically important to note that failure to maintain the Asset Protection Zone
(APZ) will compromise its effectiveness, leading to an elevated bushfire risk to the
proposed development.



4.7    Bushfire Attack Level and Construction Requirements
Where considering the application of the designed Asset Protection Zone, the overall
Bushfire Attack Level (BAL) for the proposed development has been assessed as
being BAL-12.5.

BAL-12.5 is primarily concerned with protection from ember attack and radiant heat
up to and including 12.5 kW/m² where the site is less than 100 m from the source of
bushfire attack.

To meet the construction standards outlined in AS3959:2018, both Section 3
"Construction General" and Section 5 "Construction Requirements for BAL-12.5"
should be adhered to.

To assist in managing the impacts of bushfires in Queensland, the Queensland
Government has developed guidelines aimed at enhancing the resilience of both
new and existing homes. These guidelines provide practical, site-specific
recommendations on building design and landscaping measures to improve bushfire
resilience.

It is recommended that the client refer to and apply these guidelines to strengthen
the bushfire resilience of the dwelling.
