An environmental engineer who helped move an entire Australian town to higher ground after catastrophic flooding says if people are at risk of repeat weather events, then relocation should be on the table. More than 12 people died when a metres high wall of water flooded Grantham west on Brisbane in 2011, but it was not the first time the town had been hit. A swift decision was made to up-sticks and essentially move it up a hill. Managed retreat is an issue for a number of New Zealand towns and cities as extreme weather become more frequent. Environmental engineer, Jamie Simmonds was project director for the Grantham move, which he says was time critical.
