                                                     methodologies identified by this report seek to
                                                     provide for increased resilience in addressing
                                                     matters such as built form, asset protection
                                                     zones, building and landscaping provisions,
                                                     property maintenance, access and egress and
                                                     evacuation.
                                                     The existing approval conditions require this
                                                     report including its attachments to be provided
                                                     to the local Fire Brigade for their information
                                                     purposes.

                                                     chemicals must be stored indoors and ideally

    associated with the natural hazard               which combined, seek to effectively balance
                                                     the natural features and processes associated
                                                     with the subject land and surrounding land, and
                                                     the required hazard mitigation approaches.
                                                     The measures and methodologies outlined in
                                                     this report remain cognisant of this strategic

                                                     surrounds the land.

Additional SPP bushfire-related guidance material is anticipated to be released by the Department
of State Development, Manufacturing, Infrastructure and Planning in the near future however, as
this report relates to previously-approved development such forthcoming amendments to the SPP
are not relevant.

5.3         AS 3959 – Construction of Buildings in Bushfire Prone Areas
The AS3959 – Construction of Buildings in Bushfire Prone Areas specifies requirements and measures
for residential buildings constructed in bushfire prone areas. Bushfire attack levels (BALs), which form
the foundation upon which AS3959-2009 is applied, distinguish the level of attack buildings (and
occupants) may experience based on a range of factors which are analysed at Section 6 below.

A BAL is defined as ‘a means of measuring the severity of a buildings potential exposure to ember
attack, radiant heat and direct flame contact, using increments of radiant heat expressed in
kilowatts per metre squared, and the basis for establishing the requirements for construction to
improve protection of building elements from attack by bushfire’ (Standards Australia, 2011).

The level of attack buildings may experience is based on a range of factors including vegetation
typologies (fuel load), effective slope and separation distance, each of which has a significant
