SEVEN sites in the Redlands have been highlighted as at risk of storm tide inundation during extreme weather and in a confidential report presented to Redland City Council last week.
The council will conduct further modelling to assess the level of risk for the areas in Thorneside, Birkdale, Cleveland Point, Thornlands, Victoria Point and Redland Bay after the report said they could be "partly inundated during a 100 year storm tide event under enhanced climate change conditions".
Councillor for Birkdale and Thorneside, Helen Murray, said she was "very concerned" at the public naming of the sites, but the council's chief executive, Gary Stevenson, said the information was not new as the areas were already subject to various tide overlays in the Redlands Planning Scheme.
Thornlands and Cleveland South councillor Debra Henry said she could "barely believe" the wording used in the report and, rather than "aiming to allay residents' fears", the council should be using higher sea level predictions than the rise of 0.3m by 2059 and 0.8m by 2109 used in the report and used in State Government modelling.
"These levels come from the International Panel on Climate Change (IPCC), which is known to be conservative, while Professor Will Steffen, a federal government advisor with the ANU Climate Change Institute, says we could see rises of up to 4m this century - why aren't we using the worst case scenario?" Cr Henry asked.
It comes the same week as the council made a submission to the State Government's Draft Coastal Management Plan, which seeks to give increased responsibility to councils.
Simon Baltais, of the Wildlife Preservation Society of Queensland, Bayside Branch, endorsed Cr Henry's comments regarding the use of increased sea level predictions in his submission to the government.
"Our reliance upon [outdated data] will put life and property at risk," he said.
"Unless contemporary projections are considered there seems limited scope to accommodate retreating coastal habitat except within a few suitable conservation reserves... Consequently there will be extensive losses in fishery resources, homes and infrastructure."
The council will now conduct further modelling for the 'at risk' sites, and initiate mapping for the Southern Moreton Bay Islands, Dunwich, Amity Point and areas surrounding Tingalpa Creek as they were not included in the initial report.
The report will not be publicly released until the methodology has been endorsed by the Department of Environment and Resource Management (DERM), and will be used in the council's Climate Change Strategy which is due in June 2010.
