  1. Version 4 : January 2012 Integrated Planning and Building Framework for Bushfire in Victoria Hazard Level Hazard Description Hazard Criteria Statutory Response Key Responses Vegetation Exemptions Extreme and Significant Bushfire Hazard (BHL2) Areas of extreme and significant fuel loads where there is potential for bushfire behaviour such as a crown fire, significant levels of radiant heat and extreme ember attack. • Vegetation patch size of 4ha or greater with a 150 metre ember protection buffer applied. • Locations potentially subject to extreme ember attack and other extreme bushfire behaviour. BUSHFIRE MANAGEMENT OVERLAY (Planning Schemes) • Responses are: • Planning permit requirement for new homes, subdivisions and vulnerable uses. • New development to be accompanied by bushfire protection measures (defendable space, construction standards for bushfire, access, siting, water, consideration of the wider landscape). • New residential lots created with bushfire protection measures approved and no need for any further bushfire approvals. 10/50 Rule (clause 52.48) • Responses are: • New development to be accompanied by bushfire protection measure : construction standards for bushfire. This is determined using AS3959 : 2009 Building in a Bushfire Prone Area. • Requirement for ember protection in new development. • No requirement to repeat a bushfire site assessment if undertaken under the Bushfire Management Overlay. 10/30 Rule (clause 52.48) Moderate to High Bushfire Hazard (BHL1) Areas with unmanaged grasslands and smaller patches of more significant vegetation where there is potential for moderate to high bushfire behaviour such as a crown fire, grass fire and ember attack. • Vegetation patch size of 2ha or greater with a variable ember protection buffer of 60 metres, 150 metres or 300 metres depending on vegetation type. • Unmanaged grasslands. • Other locations potentially subject to ember attack. BUSHFIRE PRONE AREA (Building Regulations) Low Bushfire Hazard (BHL Low) Areas where the extent, configuration and/or management of vegetation means there is low potential for bushfires. • Areas where the criteria for an extreme / significant bushfire hazard or moderate to high bushfire hazard is not met. 10/30 Rule except listed Melbourne LGAs (clause 52.48) INTEGRATED PLANNING AND BUILDING FRAMEWORK A response to the 2009 Victorian Bushfires Royal Commission
