Pyramids Beach the focus of coastal work
Work will begin this week to ensure safe navigation at the entrance to the Dawesville Cut and sandy beaches to the north are maintained.
Department of Transport (DoT) General Manager of Coastal Infrastructure Steve Jenkins said the annual sand bypassing project would see about 100,000 cubic metres of sand relocated.
“To maintain the natural northward flow of sand along the coast, accumulated sand is excavated from Pyramids Beach and pumped north of the entrance to the Dawesville Cut via pipes on the seabed,” Mr Jenkins said
“This ensures the entrance channel remains navigable and beaches located north of Dawesville receive the supply of sand they require to limit erosion in winter.
“Beach goers are urged to observe by the directional signage in place and abide by the restrictions until the completion of work in mid-June this year.”
The works will be undertaken using a mobile material screening, pumping and conveying equipment designed to transfer materials cost-effectively over long distances and a long reach excavator.
Environmental monitoring and management is key to the project which is expected to cost $910,000.
DoT is working with the local community including local schools and sports clubs to minimise inconvenience.
