Flood maps

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

The following maps provide information on flood affected areas and the likelihood of flood. Maps are best viewed using a larger device.

Flood depth map

Use this map if you live in a flood risk awareness area or want to know if a property is in a flood risk awareness area. The map is based on the likelihood of a rare flood event occurring (1% annual chance).

This map reflects the flood depth based on defined flood level and estimated ground level mapped in the City Plan. If you want to buy a property or build on or develop land, you can see if a property is in a flood risk awareness area as well as the approximate flood depth and defined flood level for each property. For more information, visit City Plan interactive mapping.

Flood risk awareness map

This map is the newest city-wide flood map based on our latest flood modelling. It is made available for flood risk awareness information only. The map will be reviewed by the State Government in 2023 as part of the proposed Designing for Flood Major Update to the City Plan.

We considered how deep and how fast flood waters would be in different statistical flood scenarios for city planning purposes and we have included all our city floodplains on the map.

Flood risk is calculated using 'likelihood of occurring' and flood hazard information. The map has the following flood risk categories:

Map key category Description
Maximum regional flood extent Only floods in very rare to extreme flood events (very low likelihood of occurring). The maximum extent of the floodplain associated with extremely rare events and can include flood hazard of any type (low to very high).
Low risk Exposed to relatively lower hazards during a frequent or infrequent flood event. High flood hazards can only occur during a rare and extremely rare flood event, when it is unsafe for people and vehicles and buildings may be damaged by the movement of flood water.
Medium risk Unsafe for people and vehicles and buildings may be damaged by the movement of flood water during a rare flood event. Flood events can either be rare with high flood hazard or relatively frequent with lower flood hazard.
High risk Unsafe for people and vehicles and buildings may be damaged by the movement of flood water. Flood events are both relatively frequent and usually of a high flood hazard.
Very high risk Unsafe for people and vehicles and buildings may be damaged by the movement of flood water during a frequent flood. Flood events are both frequent and usually of the highest flood hazard.
