Risk-based land use planning for floodplains in Queensland, Australia

Queensland Reconstruction Authority, 2012: Planning for stronger, more resilient floodplains: Part 2 – Measures to support floodplain management in future planning schemes.





The Queensland Reconstruction Authority saw an opportunity to learn from the weather events of 2010/11 by ensuring that resilience to flooding events is built into the new generation of planning schemes.






Provides guidance on land use strategies for development in existing infill and greenfield areas, including: undertaking a planning evaluation to balance flood hazard with other land use considerations to identify planning-specific flood risk; land use response strategies for existing and future development; and how a planning scheme can address the strategies.






To help planners understand the investigations needed to identify flood hazard and the issues to consider in developing appropriate land use responses.



Key points about method


  • Takes a risk-based approach
  • Section 3 – Implementation outlines selecting a likelihood; key elements of consequence (exposure + vulnerability – tolerability); and uses a matrix of likelihood x consequence to give a level of risk i.e. broadly acceptable, tolerable, and generally intolerable.
  • Provides example assessment criteria and planning provisions based on levels of risk


Things to consider


  • Requires good hazard information
  • Provides good, easy to understand information with diagrams to explain concepts
  • Is based within the Queensland planning regulatory requirements


When to use this approach?


  • Useful comparative approach,
  • Justifies the usage of the risk-based approach
  • For specific floodplain management
