ERSA personnel have completed bushfire risk management strategy studies for Pine Rivers Shire, Queensland; Brisbane City, Queensland; Caloundra City, Queensland; Maroochy Shire, Queensland; Beaudesert Shire, Queensland; North Stradbroke Island, (Redland Shire, Queensland) and Logan City, Queensland.
These studies produced a series of strategies for implementation by the local authority to mitigate the risk and reduce the impact of bushfires within their areas of control. The studies upgraded hazard mapping (to a resolution of 25m) and mapped fire risk using an analysis of property exposure and community vulnerability. In particular, they provided recommendations in respect of special conditions or controls applicable in high-risk areas at the time of development needed to mitigate bushfire hazard and risk.
A key feature of the studies was the development of a dynamic hazard mapping and risk analysis system for inclusion in the Council’s information and decision support system. This included the development of a fire potential monitoring methodology, using NDVI values and long term climatic data at a resolution of 1 km. The studies also examined proposed mitigation strategies and any legislative changes resulting from the recent NSW and ACT bushfire disasters experience and addressed the latest requirements of the Building Code of Australia.
The result was the development of a Bushfire Disaster Risk Management Strategy including a Counter Disaster Planning document; and a strategic planning document specific to the needs of the local authority.
The interim reports of the Victorian Royal Commission into the 2009 “Black Saturday” bushfires were also reviewed for implications for the current bushfire management strategies employed by Brisbane City Council.
