Bushfire Management Overlay
The Bushfire Management Overlay (BMO) is a planning control applied to land that may be significantly affected by bushfires. A planning
permit will be required for certain developments within this overlay including the construction of accommodation amongst others.
The planning application requirements of the BMO include a Bushfire Management Statement (BMS). The BMS makes recommendations relating
to construction standards, defendable space, vegetation management, access and water supply. A Bushfire Management Plan (BMP) forms part
of the BMS and shows the bushfire protection measures that will be implemented as part of a development to reduce the risk from bushfire
to an acceptable level. This BMP will be endorsed and form part of the planning permit.
There are some exemptions from applying for a planning permit under the BMO which include:
An alteration or extension to an existing building used for a dwelling or a dependent persons unit that is less than 50 percent of the gross
floor area of the existing building;
An alteration or extension to an existing building (excluding a dwelling and a dependent persons unit) that is less than 10 percent of the
gross floor area of the existing building;
A buildings or works with a floor area of less than 100 square metres not used for accommodation and ancillary to a dwelling.
Bushfire Prone Areas requiring BAL’S
Bushfire Prone Areas are defined as areas that are subject to, or which are likely to be subject to, bushfires. Construction in these
areas may require a Bushfire Attack Level Assessment (BAL) to specify the construction requirements.
Once assessed, your site will be defined one of six BAL ratings:
BAL – 12.5: Ember attack.
BAL – 19: Increasing levels of ember attack and burning debris ignited by windborne embers, together with increasing heat flux.
BAL – 29: Increasing levels of ember attack and burning debris ignited by windborne embers, together with increasing heat flux.
BAL – 40: Increasing levels of ember attack and burning debris ignited by windborne embers, together with increasing heat flux and with the
increased likelihood of exposure to flames.
BAL – FZ: Direct exposure to flames from fire, in addition to heat flux and ember attack.
Our experienced planners are familiar with the requirements of the Bushire Management Overlays and Bushfire Prone Areas. For application
that require specialist advice or documentation, Prossor Town Planning has professional relationships with a number of specialised fire
consultants who can assist with the above services. Please contact us to discuss this further.
