Residents will retain access to information about rare floods under changes to the city’s flood portal, resolving an issue councillors left undecided during last week’s major flood-mapping overhaul.
Logan City Council endorsed the revised portal and property reports on Wednesday 14 October, a week after deferring the matter amid disagreement over how prominently rare flood risks should appear.
Under the changes, standard property reports and the portal’s main maps will focus on floods with a 1% chance of occurring in any given year, commonly called one-in-100-year floods.
Information about rarer floods, up to a one-in-2000-year event, will remain available through the portal and detailed property reports.
However, Probable Maximum Flood mapping will be removed entirely from the portal, property reports and planning scheme.
Cr Jon Raven said the council had responded to community feedback.
“We’ve listened to the community and worked hard to get the balance right,” he said.
“These changes will make sure the portal is a simple and easy tool to use, with the most relevant information for residents up front.”
The council also confirmed it had submitted its proposed Temporary Local Planning Instrument to the Queensland Government for approval.
The proposal is expected to remove approximately 26,820 properties from the city’s flood planning overlay, reducing the total from 47,225 to 20,405.
However, the number of properties classified as Localised Flood Assessment Areas would increase from approximately 2474 to 3370.
A council spokesperson previously confirmed those properties were already mapped, but some owners proposing development may need to commission additional flood assessments.
The Temporary Local Planning Instrument must receive ministerial approval before returning to council for adoption.
Both the planning changes and revised flood portal are expected to take effect in early 2027.
The council will also continue reviewing submissions and investigating creek flooding, with that work expected to finish in 2027.
