Stormwater Outlet Upgrade - Narrawallee Beach - Victor Avenue, Narrawallee

The proposed activity is the upgrade of the stormwater outlet and outflow onto Narrawallee Beach.
The purpose of the proposed activity is to reduce the erosion of the beach escarpment currently occurring below the existing outlet. The outlet was assessed as high risk for asset damage. If the erosion is not abated, civil infrastructure could become exposed and become vulnerable to damage. This infrastructure includes the public road (Victor Avenue) and nearby gravity and pressure rising sewer mains.
The proposed activity includes:
• demolition of the existing headwall and replacement with junction pit,
• installation of flexible stormwater pipe of approximately 16 metres in length from the newly installed junction pit to the sandstone rock platform at the beach,
• installation of a stacked rock outlet headwall
• associated earthworks and sewer protection works
• earthen filling and stabilisation through erosion control and revegetation
Access woudl be from Victor and Surfers Ave.
