New hydrological studies have led Brisbane City Council to change how 8000 properties are classified on flood overlay mapping.
With Brisbane built on a flood plain, the updated maps will now be incorporated into the City Plan and influence future development, while also helping people prepare for future natural disasters.
According to the council, the studies were routine and the findings reflect changes in catchment conditions and best-practice flood modelling.

More than 8000 properties in the Kedron Brook, Brighton Creek, Toowong Creek, Sandy Creek and Witton Creek catchments will be affected by the changes. The council has yet to detail the affected suburbs and streets.
Almost 1000 properties will be removed from the flood overlay maps altogether, while others will be reclassified to reflect either an increased or decreased risk of creek flooding.

“We’re continually seeking the most recent and detailed information to inform the range of free flood resources council offers to residents,” said Cr Tracy Davis, chair of the environment, parks and sustainability committee.
“No flood is the same, and we must ensure residents are armed with the correct information to help them prepare based on their own flooding risk.
“We can’t stop severe weather, but we can be better prepared, and that’s exactly what these updates are for.”
