Northern Beaches Council’s Narrabeen Lagoon entrance clearance works are delivering on a critical project to improve the flood resilience of one of the region’s most iconic natural assets.
Over the past few months Council has removed more than 30,000 cubic metres of sand from the mouth of Narrabeen Lagoon, improving water flow and reducing flood risks for nearby homes and businesses.
The sand has been used to renourish the beach along the stretch of South Narrabeen and Collaroy Beach (with sand placement via Mactier Street to the north and via Collaroy Beach Reserve to the south), Lagoon Street Reserve and eroded sections along the Pelican Path area.

Mayor Sue Heins expressed her gratitude to the community for their patience during the works and highlighted the importance of the project.
“This proactive approach is all about reducing flood hazards and supporting our beaches. Narrabeen Lagoon is not only an environmental treasure but also a vital part of our community’s way of life. These works ensure the lagoon remains safe, accessible and beautiful for everyone.
“We are proud to have delivered this important project ahead of the busy summer holiday period. I want to thank residents, local businesses and visitors for their understanding as we carried out these essential works,” Mayor Heins said.
The project forms part of Council’s ongoing Narrabeen Lagoon Entrance Management Strategy and was delivered with support from the Commonwealth Government through the NSW Flood Recovery and Resilience Grant Program.
The Narrabeen Lagoon entrance has been reopened but the water level in the lagoon is currently quite low and with the current swells there is a chance that it will close again quickly. If this happens the contractor will re-attempt when conditions are more favourable.
