Sorrento Beach Groynes Undergo Essential Repairs with Temporary Closure
The City of Joondalup has announced that repair work on the central and southern groynes at Sorrento Beach will commence this month, necessitating the closure of sections of the beach for several weeks. The project, scheduled to begin on April 7 and conclude by early June, involves adding limestone and granite while reshaping the existing rock structures to address deterioration and meet current coastal protection standards.
Critical Role of Groynes in Coastal Management
Acting Joondalup CEO Nico Claassen emphasized the importance of the groynes, stating, "All three structures remain essential for maintaining beach width and amenity along this stretch of coastline, and they play a critical role in limiting the natural northward movement of sand, helping to protect the beach south of Hillarys Boat Harbour." The groynes, constructed over 40 years ago between 1983 and 1985, were originally built to trap sand and prevent erosion, safeguarding West Coast Drive, the Sorrento Surf Life Saving Club, and adjacent buildings behind the limestone seawall.
Logistics and Safety Measures for the Repair Project
During the repair works, access to the beach around the groynes will be blocked, and the southern carpark at the Sorrento Surf Lifesaving Club will be closed and fenced off. Operations will run from 7am to 5pm, Mondays to Fridays, excluding public holidays. The city urges beachgoers to stay clear of the work area to ensure safety and allow for efficient completion of the repairs.
Controversial History and Funding Details
Rock groynes have been a contentious issue among local residents. In 2023, a $120 million proposal by the City of Joondalup to build 17 groynes along the 5km coastline between Hillarys and the Ocean Reef marina was abandoned after over 5000 people opposed it, citing concerns about disrupting the continuous beach stretch used for walking and swimming. This proposal was part of the draft 2023 Coastal Hazard Risk Management and Adaptation Plan, which is now being revised with community input and expected to be completed by 2027.
The current repair project was approved by the Joondalup council in February, with the tender awarded confidentially. Funding is provided through a joint arrangement: 75% from a grant under the Australian Government's coastal and estuarine risk management program, totaling $1.281 million over three years, and the remaining 25% from the city's own resources.
Implications for Beachgoers and Future Coastal Plans
While the temporary closure may inconvenience visitors, the repairs are deemed necessary to preserve the beach's integrity and functionality. The city's ongoing efforts to balance coastal protection with community preferences highlight the complex challenges in managing erosion and maintaining public amenities along Perth's northern coastline.
