This section of coast is subject to erosion hazards and overtopping at the Ocean Grove seawall. This will have implications for future risk assessments. It is recommended that closer monitoring of the beach is undertaken to track coastal change and provide better background information for future assessments.
The seawall at Ocean Grove Main Beach is providing a high standard of protection to the hinterland presently. Overtopping volumes are generally low for the present day. Beach levels at the toe of the seawall are likely to decrease due to scour erosion, therefore increasing the depth of water at the toe of the structure during storm conditions. This in turn will allow larger waves to penetrate further inshore and increase overtopping. The rate of loss of beach volume is currently unknown, and should be monitored to inform future assessments.
