Flood maps

If you are looking to buy, build on, or otherwise develop a property you can use the mapping tool below to check if your property is in a flood affected area. If your property is in a flood affected area this tool approximates the extent and depth of flooding in a rare 1% probability of a flood event occurring in any year (1% Annual Exceedance Probability (AEP)).

This map is meant for future flood planning purposes. If you are developing on land that is identified within the map, you will need to review the necessary provisions in the flood overlay code and may need to submit a development application. For more information on development applications, visit Development application pre-lodgement advice.

For information during a rain or flooding event, please refer to the city's emergency dashboard – dashboard.cityofgoldcoast.com.au/

Note: If your property is not within the hazard areas that are subject to flood, this does not mean you are immune to flooding. This may be because:

  • There is always a possibility of having rarer rainfalls that may overwhelm our protection measures.
  • There may be small creeks on higher grounds that are not fully included in our models yet. These creeks may experience flash flooding, causing short-term overland flooding.
  • Blockages to drainage systems and restrictions to the flow of water in waterways can result in flooding.
  • A property may be on an overland flow path which is yet to be included in the Flood Planning Map.

City Plan Flood overlay map

The City Plan Flood overlay map commenced as part of Version 6 of City Plan on 20 September 2018. Both the mapping above and the City Plan Flood overlay map consider future changes to climate. They incorporate the projected increase in sea level of 0.8 metres above present-day levels and 10% increase in storm tide intensity by 2100, as established by the State Government in 2015. They also include a 10% increase in rainfall intensity to account for the impact of climate variability on the city's hydrology, following advice from industry representatives.

We are currently reviewing our flood maps including the City Plan flood overlay map – further information can be found at the ‘Flood overlay mapping’ tab on the City Plan amendments page.
