A large sand bank off the coast of Exmouth could be dredged and used to shore up Dawlish Warren and Exmouth beach.
The scheme, which would see sediment taken from Pole Sands, is currently being studied by Teignbridge and East Devon District Councils, and was presented to Exmouth Town Council this week by Teignbridge officer Graeme Smith
Councillors had previously raised concerns about the plan, saying that reducing the level of Pole Sands could leave Exmouth seafront open to bigger waves and flooding.
But Mr Smith insisted that any dredging on Pole Sands would only take place at the furthest point from the shore, and the flood risk to Exmouth would not be increased.
He said the action was vital to protect Dawlish Warren, which could receive around 115,000 cubic metres of sediment from Pole Sands.
