Integrated Planning and Building Framework Regulatory responses

Areas where the extent, configuration and/or management of vegetation means that there

is low potential for bushfire spread.

Three levels of site-based response

BUSHFIRE HAZARD LEVEL LOW AREAS

BUSHFIRE HAZARD LEVEL 1 AREAS

Areas of high to extreme fuel loads where there is potential for high bushfire behaviour

such as a crown fire and ember attack

BUSHFIRE HAZARD LEVEL 2 AREAS

Areas of extreme fuel loads where there is potential for extreme bushfire behaviour such as a crowning fire and extreme ember attack

Planning response : Bushfire Management Overlay (BMO)

AND

Building response : Bushfire Prone Area (BPA) and the

Building Regulations
