Flood — Awareness — Flood Risk Overall

This dataset, created in June 2013, provides an indication of the likelihood of a flood occurring from one or more sources: creek, river, and storm tide inside the Brisbane City Council local government area. This layer contributes to the overall Flood Awareness Mapping for Brisbane City Council.

Brisbane City Council has developed the Flood Awareness Maps and adopted the terms ‘high’, ‘medium’, ‘low’ and ‘very low’ likelihood areas to help residents and businesses better understand the likelihood of a flood affecting their property. The Flood Awareness Maps are an awareness tool and the maps do not provide information about the depth or speed of flood water. Information on potential flood levels for a property can be found in the FloodWise Property Report online.

The Flood Awareness Maps are an awareness tool to provide an indication of the likelihood of a flood occurring from one or more sources: creek, river, overland flow and storm tide. The maps do not provide information about the depth or speed of flood water. Use the FloodWise Property Report for information about flood levels specific to your property.

Many properties within the high and medium flood likelihood were affected by flooding in the 1974 and 2011 Brisbane River floods.

Residents in the low and very low flood likelihood areas should still be aware of their risk of flooding and understand how they, as well as others in the area, may be affected.

High likelihood area

Flooding is almost certain to occur in a high likelihood area. Residents and businesses are strongly advised to learn about the flood likelihood for their property so they can be prepared to help minimise the impact on their home, business and family.

Medium likelihood area

Flooding is likely to occur in a medium likelihood area. Residents and businesses are advised to learn about the flood likelihood for their property so they can be prepared to help minimise the impact on their home, business and family.

Low likelihood area

Low flood likelihood areas may experience flooding in a rare flood event. Residents and businesses should consider how flooding may affect their local area, suburb or community. Flooding is unlikely in a low flood likelihood area but it may still occur.

Very low likelihood area

Very low likelihood areas are unlikely to flood except in a very rare or extreme flood event. Residents and businesses should consider how flooding may affect their local suburb, area or community. Flooding is very unlikely in a very low flood likelihood area, but may still occur.

Brisbane City Council is working hard to reduce the impact of flooding but we all have a responsibility to understand our flood risk and be better prepared to minimise the impact of flooding on our homes, property and businesses.

This dataset uses Brisbane City Council's Open Spatial Data website to provide extra features for viewing and downloading the data. The first two resources in this dataset are labelled HTML and they each have a Go to button. Clicking a Go to button will open a web page in a new tab. The Go to button on the first resource will open our Open Spatial Data website that provides many features for viewing, interacting with, and downloading data. The Go to button on the second resource will open the ArcGIS REST Services Directory website and display the spatial metadata for the dataset. Most of our spatial datasets have four more resources. The four resources are labelled: CSV, GeoJSON, SHP, and KML, and all four have a Download button. Clicking the Download button on the CSV resource will download the attribute data in a table. Clicking the Download button on the GeoJSON, SHP or KML resource will download the data in a spatial file.
