Gold Coast Flood Map: How to Check Your Property's Flood Risk
If you are checking whether a Gold Coast property floods, the City of Gold Coast publishes several flood maps, and knowing which is which helps you read them correctly.
The Flood risk awareness map is the city-wide map based on the City's latest flood modelling. The Flood insurance map shows five different flood scenarios, and the Flood depth map is based on the likelihood of an infrequent flood event. You can also run a Flood level search to see the flood information the City holds for a specific property, and check the City Plan interactive mapping. Together these show whether a site sits within the City's mapped floodplains.
The Gold Coast is vulnerable to both riverine and overland flooding, and low-lying coastal and canal-estate land can behave differently again. A map tells you a site is flood-affected; it does not tell you how a particular development will perform, what floor levels or design a proposal needs, or how water moves across your specific block. That is the work of a flood engineer - a Flood Impact Assessment or design advice so a project meets the City's requirements.
It is worth involving a flood engineer when you are buying and want certainty about a flood-affected Gold Coast site, lodging a development application on flood-affected land, or resolving a flood-related requirement.

Frequently Asked Questions
How do I check if my Gold Coast property floods?
Use the City of Gold Coast flood maps - the Flood risk awareness map, Flood insurance map and Flood depth map - and run a Flood level search for a specific property.
Which Gold Coast flood map should I use?
The Flood risk awareness map is the city-wide view from the latest modelling, the Flood insurance map shows five flood scenarios, and the Flood depth map reflects an infrequent flood event. A Flood level search gives the information the City holds for one property.
Is a flood map enough for a development application?
It is a starting point. Development on flood-affected Gold Coast land usually needs a flood engineer's assessment of how the specific site and design respond, not the map alone.
