Erosion prone areas

On 8 July 2015, the Department of Environment and Heritage Protection declared new erosion prone areas for the Queensland coast. The new erosion prone area re-introduces climate change factors (including a sea level rise factor of 0.8 metres and updates the shoreline position. It is very similar to the erosion prone area rescinded in 2014.

The erosion prone area is the width of the coast that is considered to be vulnerable to coastal erosion and tidal inundation.

Calculation of the erosion prone area is based on: 

  • a short-term erosion component from extreme storm events
  • a long-term erosion component where gradual erosion is occurring commonly from channel migration or a sediment supply deficit
  • a dune scarp component, where slumping of the scarp face occurs following erosion;
  • erosion risk due to future sea level rise from climate change both by permanent inundation of land by tidal water and the morphological response of the coast to elevated water level
  • a 40% safety factor.

The Coastal hazard technical guide (PDF, 348K)* provides additional information on coastal erosion and storm tide inundation and assessment of erosion prone area widths. More information concerning management of erosion prone areas can be found on the shoreline erosion management planning page.

Erosion prone area mapping

Statutory erosion prone areas are declared under section 70 of the Coastal Protection and Management Act 1995 (Coastal Act) by reference to an erosion prone area plan.

These plans are to be used for development assessment purposes, and to inform the preparation of planning instruments, such as planning schemes and regional plans under the Sustainable Planning Act 2009.

Erosion prone areas have been declared for all coastal local government areas. The statutory plans detailing them are available and accessible using the following table.

Coastal hazard area mapping

Coastal hazard areas consist of areas at risk from sea erosion or permanent inundation from tidal water and areas of temporary inundation resulting from a defined storm tide event. The mapping products include erosion prone area maps as well as storm tide inundation area maps.

These maps will be used to inform governments, businesses and the public about the geographic extent of hazard areas, and to inform decision-making in relation to the protection of vulnerable coastal communities and when assessing development applications.

While the erosion prone area plans specify the linear inland extent of the erosion prone area from tidal waters, the coastal hazard area maps interpret this and indicate the footprint of these areas on the ground. Care should be used when referring to the indicative map as the erosion prone area location may change over time. If there is any doubt about the location of the erosion prone area, then the declared erosion prone area plan prevails over the indicative footprint maps and a ground survey may be required to accurately define the location.

To access the coastal hazard area maps, see Coastal Management Plan—Maps. These maps are available to be viewed at property scale, or via the map sheets index.

Changing the erosion prone area

The erosion prone area plans are updated periodically as more detailed on-ground studies are incorporated into the mapping. Any dispute about the extent of the erosion prone area must be accompanied by a report from a suitably qualified person using the methodology outlined in the Coastal hazard technical guide (PDF, 348K)*.
