Kingscliff's $500k cleanup bill
THE effort to permanently protect public assets at Kingscliff from the encroaching sea is expected to cost about $500,000.
Up to 60 metres of vegetated dune has been lost from foreshore stretching about 200m from the northern break wall of Cudgen Creek.
Tweed Shire Council's (TSC) Co-ordinator Natural Resource Management, Jane Lofthouse said the erosion was an “entirely typical process”, but council was now acting because the access road to Faulks Park under threat was too valuable to lose.
Work has already been carried out to save remaining pandanus trees and further efforts to stem the progression of erosion started on Monday and will cost about $50,000.
Ms Lofthouse said the erosion scarp would be battered and backfilled with sand. It will then be covered with a high grade geotextile material, secured at the bottom with a combination of concrete blocks and sand filled geotextile bags.
But neither of those products are available in sufficient quantities right now and the large sand bags may take three weeks to become available.
She said council had requested a licence from the Land and Property Management Authority to dredge the creek so the sand could be used to nourish the beach. Boat access to the creek would also be improved in the process.
“This will go in some way to restore the dune system, however, the volumes available will not provide a large buffer,” she said.
“The success of these works is dependant upon the flow of sand being reinstated in the near future which will see the beach and dune reform over time.”
Ms Lofthouse said the “erosion cell” that caused the problems near the break wall had moved north and further erosion was occurring closer to the Cudgen Headland Surf Life Saving Club.
