Whitehill Road Geotextile Sand Container Groynes

In July 2018, Council made the decision to construct two low-crest 40m long Geotextile Sand Container (GSC) groynes on the Drummond Cove Foreshore to mitigate coastal erosion at Whitehill Road.

These groynes, which extend across the beach and into the ocean, have been designed to retain sand at Whitehill Road and reduce reliance on temporary sand nourishment operations. Works on the project were completed in December 2018. More here  

In 2020, the City received funding from the WA Recovery Plan to address coastal erosion at Drummond Cove and constructed a third Geotextile Sand Container (GSC) groyne at Whitehill Road and undertook sand nourishment of the foreshore.  More here

Sunset Beach Geotextile Sand Container Groyne and Revetment

The Sunset Beach Foreshore has been experiencing coastal erosion which has lead to the removal of City assets to prevent them from falling into the ocean.

The City engaged M P Rogers & Associates to investigate and provide advice on potential coastal adaptation options for Sunset Beach.

In Late November 2019, construction of a low-crest Geotextile Sand Container (GSC) groyne and revetment on the Sunset Beach Foreshore to mitigate coastal erosion was completed. A 40m low-crest GSC groyne and 50m long GSC revetment constructed at Triton Place will help retain an initial beach nourishment.  More here

Beresford Foreshore Coastal Protection and Enhancement Project

In January 2017, work began on one of the City's largest capital works projects to date.  Project works involved building a 100m long extension to the detached breakwater at Midalias Beach, a 45m long extension to the existing marina groyne and three shore based rock revetments between Mark Street and Mabel Street.  Protection woks were completed in later that year.  More here

The second stage, or Coastal Enhancement Works, which involved replacing amenities lost to coastal erosion over the years and landscaping works began in January 2018 and was completed in October 2018. More here

St Georges Beach Groyne

In mid 2016, the City installed a low level Geotextile Sand Container (GSC) groyne at the north end of the carpark to mitigate coastal erosion. These medium-terms works are complimented by the Mid West Ports Authority Northern Beaches Stabilisation Programme sand bypassing works.  More here
