Crockatt Park - Seawall Renewal


Project background

Council is upgrading coastal protection structures around Crockatt Park, Woody Point. The existing seawall currently extends from Woody Point Jetty to the Crockatt Park Boat Ramp and is in poor condition.

Council has engaged specialist engineering consultants to provide a new seawall design for the area. This is to protect public and private infrastructure from erosion and wave overtopping during storms.

New seawall concept

The existing seawall is to be replaced with a new concrete stepped seawall. The new arrangement is designed for a 100-year design life and considers the effects of sea level rise. The steps allow for better access to the beach foreshore and use an aesthetically-pleasing geometric design.

Immediately north of the Crockatt Park Boat Ramp, further works are also proposed. The beach will be nourished with sand, lengthening and widening the area available for recreation. Large sandbags, which will only be exposed during severe erosion from storms, are to be buried at the rear of the beach to protect footpath and car park areas.

Detailed design and construction

Council are currently refining the seawall design, to be finalised by mid-2023. Construction is estimated to begin in 2024 and completed in 2025.

To ensure the proposed concept design performs during extreme events, a small physical model was created and tested. Engineers at the Queensland Government Hydraulics Laboratory created a detailed, scale model of the seawall and put the design to the test in their wave flume at Deagon. Using sophisticated wave paddles to simulate extreme storm events, the amount of water overtopping the seawall could be measured. This modelling and validation improves the confidence of the design to withstand even the most extreme events.
