Kedron properties and thousands more across Brisbane have been reclassified on the updated flood maps, reflecting new data about flood risks in areas like Kedron Brook and Brighton Creek.
Brisbane City officials plan to release the updated flood map online on 6 Dec 2024, when residents can view their full property’s revised flood classification.
However, some details of the reclassifications have already been disclosed, particularly the areas impacted and general changes to flood risk. Affected property owners will receive notification letters by early December, ahead of the public release date.
8,000 Properties Reassessed
For nearly 1,000 of these properties, the new assessments have removed them from flood risk classifications altogether, while 7,000 other properties have had their risk levels reassessed either up or down based on new data.
The changes are based on the results of new hydrological studies for Brisbane. Cr Tracy Davis, chair of the environment, parks, and sustainability committee, stated that officials continually seek the most recent and detailed information to update the range of free flood resources offered to residents.
Ms Davis emphasised that no two floods are alike, and it’s essential that residents have accurate information to prepare based on their specific flood risk. While severe weather cannot be prevented, she noted, these updates are intended to help Brisbane residents be better prepared.
Public Trust and Transparency Concerns
Public opinion about the flood map updates reveals mixed feelings, with some residents voicing concerns about the Council’s transparency and potential influences on the assessments.
On a popular Reddit forum, some users suggested that flood classifications might be influenced by the properties involved, questioning whether external factors affect these decisions. One commenter noted a general distrust in the process, pointing out a belief that assessments may favour influential interests.
However, other residents countered these claims, noting that the Council’s flood modelling is publicly available and conducted by reputable engineering firms. These users argue that the Council’s data is comprehensive and follows standard practices to ensure accuracy. There is a consensus that developers, too, treat these maps as definitive when planning construction projects, viewing them as a crucial tool for avoiding flood-related losses.
Calls for Long-Term Climate Modelling
Another concern raised by locals is that the flood maps rely on current-day scenarios without fully incorporating future climate change projections, such as those for 2050 or 2100. One resident argued that excluding these long-term models from the maps could lead to short-sighted planning, as developments built today may not be adequately prepared for anticipated changes in rainfall patterns and sea levels.
Although the updated maps are seen as a step forward regarding data accuracy, some residents feel they lack the broader perspective needed for future-proofing Brisbane’s infrastructure. Cr Steve Griffiths, representing low-lying parts of Salisbury, Oxley, and Rocklea, said sudden insurance premium hikes could take many residents by surprise, calling for greater transparency.
