Sand works questioned

Sand nourishment works at locations along the Geographe Bay coastline are set to continue throughout the winter months in a bid to slow ongoing erosion caused by storm incidents.

The work, which involves sand being moved to the shoreline to protect assets from erosion, was implemented by the City of Busselton at Broadwater beach on Allen Street and Scout Road in East Busselton following recent storms.

However, some residents raised concerns about the cost of such works, given the imminent threat of ongoing storm damage.

City engineering and works services acting director Daniell Abrahamse acknowledged sand nourishment was a temporary solution, but it provided an important buffer for assets in the short-term.

“While this imported sand does erode during severe storm incidents, it remains in the coastal system and is generally re-deposited along the coast, providing ongoing benefits,” he said.

Residents pointed to the construction of a seawall at Broadwater beach as a long-term solution, but Mr Abrahamse said it had not been considered given the “high cost” which would flow on to ratepayers.

“It would also result in the loss of the sandy recreational beach which is highly valued by the community,” he said.

The City will undertake further assessments to prioritise areas for treatment, but noted not all erosion required intervention.
