Council’s Caboolture Customer Service Centre will be relocating to Level 1, The Caboolture Hub from Monday 28 July, until Tuesday 9 September 2025.
Several flood studies and investigation reports have been developed to assist in determining flood risk in our city. These investigations are periodically updated. The data created from these studies is available in flood check property reports and on the Moreton Bay Flood Viewer.
Digital data from these studies is available by completing a Digital flood study data request.
The Storm Tide Hazard Study is a regional flood investigation that provides information about potential flooding along the coast due to storm tides. The study has been prepared using best practice methodology under the supervision of a study advisory group including:
Storm tide inundation calculations and mapping were undertaken in 2012 and updated in 2014-2016, as documented within the reports in the below section “2012-2016 Regional Flood Database Reports”.
The Overland Flow Path Mapping study investigated overland flow for the entire local government area. Overland flow is excess rainfall runoff that can cause flooding in gullies and depressions located upstream of rivers and creeks and in areas where the runoff exceeds the capacity of urban drainage systems. Overland flow is generally shallow, fast-moving and can carry debris. This report details the hydrology, TUFLOW hydraulic modelling and post-processing methodologies used within the study.
Flooding occurs when heavy rainfall causes the water levels in a river, creek or urban drainage system to rise and exceed the capacity of the main channel or pipe network. Comprehensive flood modelling has been developed for the entire local government area detailing flood risk from river, creek and urban drainage sources.
The modelling has undergone multiple updates over time. The most recent update was acknowledged by Council in early 2025.
Reports associated with prior versions of the flood studies are also available for download. It is noted that, though the majority of this content is superseded by the most recent update, the storm tide inundation and Probable Maximum Flood information contained in these reports is current. No update to Probable Maximum Flood or storm tide inundation mapping occurred as part of the update acknowledged by Council in 2025.
