Erosion prone areas
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
- a shoreline recession component due to sea-level rise associated with climate change
- a dune scarp component, where slumping of the scarp face occurs following erosion.
The erosion prone areas and storm tide inundation risks include projected climate change impacts up to the year 2100.
The Coastal Hazards Guideline provides additional information on coastal erosion 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 Part 4 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 maps display areas projected to be subject to coastal hazards by the year 2100. Coastal hazards consist of areas of permanent inundation due to erosion or sea-level rise, and areas of temporary inundation resulting from a defined storm event. The mapping products include erosion prone area maps as well as storm tide inundation area maps.
While the erosion prone area plans specify the linear inland extent of the erosion prone area from tidal waters, the coastal hazard area maps show what is potentially at risk in the future. These maps will be used to inform governments, businesses and the public about the geographic extent of hazard areas, and assist decision-making in elation to the protection of vulnerable coastal communities.
The area shown as the indicative erosion prone area to 2100 is indicative only; statutory erosion prone area plans are to be used when assessing development applications.
To access the coastal hazard area maps, please visit the Queensland Coastal Plan—Maps page. These maps are available to be viewed at property scale, or via the map sheets index.
