Objectives and benefits
We're working with Fremantle Ports to investigate options to manage coastal erosion at Port Beach.
The project is supported by the Department of Transport’s Coastal Adaptation and Protection (CAP) grant program. A project reference group has been established with representatives from local and state government agencies and community groups.
In December 2019, Fremantle Council approved the construction of a rock wall as the preferred interim measure to protect facilities including the change rooms, surf club annex and the Coast Port Beach restaurant from coastal erosion.
Port Beach coastal adaptation option detailed investigations and design
The project aims to identify additional approval that might be required to implement the sand nourishment (via dredge) option along with any further site investigations to confirm the basis of the design. This is likely to include:
- Environmental Protection Authority approvals for Fremantle Ports offshore dredging and placement of sand on Port Beach.
- Sediment transport modelling to ensure any potential impacts on the Cottesloe Reef Habitat Protection Area is acceptable.
- Funding and financial contributions from state government and identified beneficiaries for both capital and operational costs.
Sand (beach) nourishment will provide a buffer against storm erosion to a tolerable erosion hazard risk to protect the existing assets, and generally maintain Port Beach amenity.
This project is expected to take between 12–18 months. This includes detailed design investigations (between January–September 2020) and attaining all state government approvals.
The total project budget is $100,000. This involves project partner contributions by City Of Fremantle (25%), Fremantle Ports (25%) and the Department of Transport Coastal Adaptation and Protection (CAP) grant (50%)
Temporary rock wall
Works to construct the temporary rock wall were completed in March 2020, with the state government providing $200,000 towards the project.
The shape of the coastline at Port Beach is continuously changing in response to the forces acting on it including wind, currents, waves and the level of water.
Port Beach is essentially an artificial beach that was shaped by the early construction work associated with the Fremantle Harbour and Fremantle Port.
These early works placed large volumes of sand and rubble on the beach and in the nearshore area. Over time the sand placed on Port Beach has been lost due to natural coastal processes as the sediment has been transported to the north and the beach realigns to a more natural alignment.
