A third low-crest Geotextile Sand Container (GSC) groyne will be built at Drummond Cove Foreshore to expand ongoing coastal erosion mitigation works at Whitehill Road.
The works include the construction of a 37m long GSC groyne that extends across the beach and into the ocean and an initial beach nourishment of approximately 2,200m3 of sand.
The groyne has been designed to retain sand at the shoreline which will help stabilise the foreshore north of the existing groynes which underwent some changes following the installation of two GSC groynes on site in 2018.
City of Greater Geraldton Mayor Shane Van Styn said the two previously installed GSC groynes are performing well.
“Although it’s only been three years since the first two GSC groynes were built on the Foreshore, sand has been banking up so effectively on the south side of them that both groynes are nearly completely buried,” he said.
“This is an encouraging outcome that has greatly reduced the need for temporary sand nourishment operations along this stretch of coastline.
“The GSC groynes have become quite popular over the years as they allow the beach to still be used and enjoyed by the community and at any stage in the future, should they no longer be needed, the groynes can be easily removed.
“The City is very grateful to the State Government who have provided 100 percent of the project funding through their WA recovery Plan.”
The use of GSCs as a coastal adaption measure is consistent with the Geraldton Coastal Hazard Risk Management and Adaptation Plan (CHRMAP), which is based on the requirements and adaptation hierarchy of Western Australia's State Planning Policy No. 2.6 – Coastal Planning (SPP2.6).
Construction of the groyne will be undertaken by local contractor Red Dust Holdings with MP Rogers and Associates providing technical services. Works are scheduled to begin on Wednesday 16 June 2021 and will take approximately six weeks to complete.
