Beach erosion 'temporary'

TWEED Shire Council is undertaking emergency works to protect Faulks Park and an access road following continuing erosion at Kingscliff Beach.

Council’s natural resources management co-ordinator Jane Lofthouse said the erosion was due to an overall lowering of the beach profile over a long period of time.

“While it is not known exactly what processes have caused this current erosion, it is a typical process to have erosion of this scale, particularly on the northern side of a structure such as a breakwall,” Ms Lofthouse said.

“The foreshore erosion is being caused by the beach trying to level itself out. There is a sand deficit just offshore so it is compensating for this by pulling sand from the dunal system.”

Ms Lofthouse said sand-filled bags have been put in place in an attempt to slow sand movement.

“We have been able to place sandbags on a short section of the evading foreshore,” Ms Lofthouse said.

“We are allowing the erosion to continue, as it will only continue a short distance and then more sand will come in.”

The council has applied for a Crown Land licence for the dredging of Cudgen Creek to improve boating access and to use this sand for replacement of the eroded dune.

“This will go some way to restore the dune system, however the volumes available will not provide a large buffer,” Ms Lofthouse said. “The success of these works is dependent on the natural northward flow of sand returning in the near future which will see the beach and dune reform over time.”

There will be substantial costs involved in both the temporary works currently being undertaken and long-term works that need to be considered.
