The results of flood modelling studies are now available for public viewing following months of research by Council’s Hydraulics team.
Senior civil engineer, Patrick Marshall, said Glenorchy’s urban catchments were subject to flooding during high rainfall events.
“Major flood events, most recently recorded in May 2018, have caused significant losses and damage to Council’s infrastructure and also to private property.” He said.
The flood modelling study produced detailed maps showing the extent of flooding in key areas. The study considered a range of different scenarios, including the impact of a sea level rise and change in rainfall intensity caused by climate change.
Detailed information about flood prone areas allows Glenorchy residents and Council alike, to plan ahead in preparation for future flood events.
“This will not prevent flooding but we can mitigate the impact and prioritise the upgrade of stormwater infrastructure in areas shown to have a higher risk of flooding.” said Mr Marshall.
The study will also help inform emergency responses in future flood events, implement improved town planning guidelines for future development, and determine the minimum floor height for properties to reduce the likelihood of flooding.
It is recommended that all properties in identified flood prone areas have adequate flood insurance.
Detailed flood extent maps will be available to be viewed at Council Chambers from 1 July to 28 July 2021, and can also be viewed on Councils website at https://www.gcc.tas.gov.au/residents/your-home/floods-and-stormwater/
