Queensland floodplain assessment overlay

The Queensland Floodplain Assessment Overlay (QFAO) map layer identifies potential floodplains that may be at risk of inundation from riverine flooding. However, it is not intended to predict riverine flooding for specific land parcels. The map was created through an analysis of drainage patterns using data such as 10-meter contours from the best available elevation models, historical flood records, vegetation and soils mapping, and satellite imagery, rather than a specific flood modelling approach. This data serves as an interim assessment to help Local Government Authorities identify areas that may need further refinement.
