Sea levels threaten 2600 Gong properties: council

Picture: ROBERT PEETMore than 2600 properties across Wollongong will be potentially affected by rising sea levels within the next 90 years, Wollongong City Council has warned.A coastal zone study commissioned by the council has identified 2684 properties that could be affected by 2100. Detailed maps showing the combined impact of a 90cm sea level rise and a one-in-100-year storm event will be made public on Monday.The sites include 1779 privately owned properties and 905 properties owned by the council or government agencies. Homes, businesses, parks, car parks, surf clubs or other infrastructure could be affected.Woonona is deemed to be most at risk of shoreline erosion, while the rugged cliffs along the coast north of Bulli mean the northern suburbs are most at risk of instability.Thirroul, Sandon Point, Bulli, Woonona, Bellambi and low-lying areas around Lake Illawarra are most at risk of ocean inundation. Many of these areas are already affected by flooding after heavy rain.The council’s environmental strategy and planning manager Renee Campbell said all but 381 properties identified by the study already had existing flooding or geotechnical constraints.She said the council study was required to adopt State Government estimates of a 40cm sea level rise by 2050 and 90cm by 2100.”The number of properties is a lot less than what we had expected and a lot less than anticipated from the Federal Government report last year,” she said.The Federal Government had estimated up to 5000 dwellings in Wollongong could be affected, based on a projected sea level rise of 1.1m by the end of the century.Ms Campbell could not confirm the number of dwellings at risk, but said it was significantly less than earlier predictions.Ms Campbell said the council had received only five phone calls from property owners since letters were sent last week advising that their property was “potentially exposed to coastal hazards”.Affected properties will now have details of the coastal zone study noted on their section 149 planning certificates.Residents are being invited to attend one of four public information sessions next week.The first will be held at the council’s Burelli St headquarters on Monday from 6pm to 8pm.Similar evening sessions will be held at Dapto, Thirroul and Corrimal from Tuesday to Thursday.The study is expected to be tabled at the next council meeting on July 27 to be endorsed by administrators. It will then be used to prepare a coastal zone management plan by the end of next year.”Council hasn’t imposed additional development controls at this stage,” Ms Campbell said.”After the management plan is prepared, there may be some new development restrictions.”
