Mc Millan_Orsini_Workshop_What is so scary about planning for bushfire
- 1. What’s so scary about planning for bushfire? Workshop October 2013
- 2. Who are we to talk about bushfire? 2
- 3. What is the point? • Strategically and economically it makes sense • Victorian Bushfires Royal Commission • State Planning Policy Framework 3
- 4. What is the point? 4
- 6. 6
- 7. Factors affecting bushfire behaviour • Vegetation (type and structure) 7
- 8. Factors affecting bushfire behaviour • Topography (steep v flat) 8
- 9. Other factors to consider • Strategic access • Urban form that would modify the underlying vegetation (and changes bushfire behaviour) • Look at decision guidelines at Clause 52.47-3 of the VPPs Semi Managed Fuel 9
- 10. Scary and unfamiliar terminology Forms of bushfire attack • Ember attack • Radiant heat • Direct flame contact 10
- 11. Can you make some judgements? 11
- 12. 12
- 13. 13
- 14. 14
- 15. 15
- 16. So why do you think it is scary?
- 17. • The maps don’t give the answer • It is not like a flood or native vegetation • Comparing unlike things • Subjective judgements about risk acceptance
- 18. Overcoming our fears? • Accept the risk exists • Present information about the bushfire hazard to decision makers • Form a judgment on acceptable risk – what is the residual risk? Risk Assessment Acceptable Not Acceptable PANEL
- 19. Practical tools… • In most peri-urban areas we will be considering development in areas of: • lesser risk (direct development) • some risk (carefully consider and make a risk judgement) 19
- 20. Information Establish context • Collate information regarding the site and surrounds: • Locality and site description (aerials and plans) • Bushfire hazard information • • • • • • Bushfire Management Overlay, Bushfire Prone Area mapping Other Overlays – e.g. Environmental Significance Overlay Victorian Fire Risk Register rating Regional Bushfire Planning Assessment Fire history Any other relevant information 20
- 21. Information Establish context (Cont.) • Strategic justification • Why has the location been selected? • What other lesser risk locations were considered? If none, why? • Is there a structure plan (or similar) providing direction? • Does that strategic plan consider bushfire matters? • Outline of Proposal • Conceptual plan 21
- 22. Information Qualitative judgement/risk assessment • For sites where development needs to be carefully considered, additional information is required: • Landscape scale assessment • • • Bushfire behaviour (landscape and local scale) Access and egress both to the site and within the site Proximity of the site to a settlement or township area • Proposed bushfire protection measures • Other information that may be necessary: • • • More information on the proposal (vulnerability) Comments from Integrated Fire Management Planning/ Emergency Management Vegetation controls/management 22
- 23. Case Study • • • • • Vegetation, topography and other factors? What are the likely bushfire risks? Forms of bushfire attack? Mitigation measures? Relationship with other planning objectives/ requirements? • Residual risk – is it acceptable? 23
