Approximately 2,400 properties in low-lying areas of Launceston are now flood protected by structural upgrades including a 2m high FloodFree Demountable Barrier.
A 12km long flood mitigation solution in Launceston will protect the area in a 1% AEP (Annual Exceedance Probability) flood event.
Earthen and concrete levees on either side of the Riverbend Park entrance left an 18m wide access area. This section is now flood protected with a custom-designed Demountable Flood Barrier solution.
Launceston is impacted by flooding of both the North and South Esk Rivers. In the event of a flood warning, storage racks designed to include all required posts, Acrow Props and barrier segments are transported to the site for manual deployment.
Covered, permanent in-ground footings ensure fast and efficient installation. Once the cover plates are removed, the centre posts and Acrow Props are fastened to the in-ground footings. Barrier segments weigh only 6.5kg each and can be easily handled by a single person. The segments are lifted from the storage rack and slid one at a time into the frame created by the centre posts to form a flood barrier. No special skills or specialist training are required to erect the demountable flood barrier.
