Should the funding application be unsuccessful again, a decision will need to be made on whether the City invests in proceeding with the remediation fully funding the cost. If community sentiments do not support the reinstatement of the jetty a decision may be made to demolish the jetty due to the reoccuring environmental impacts, and explore future opportunity to construct another jetty in another community activated area. 

The Recreational Boating Facilities Scheme (RBFS) is grant funding available from the Department of Transport that provides grants to eligible authorities for the planning and construction of public boating infrastructure benefiting WA's recreational boating community (ref: RBFS Grant Application Form - Round 29). 

The estimated cost to remediate and construct the adapted design is approximately $876,000. This is subject to completion of detailed design and further geotechnical testing (to take place after confirmation of funding application being successful). 

Should funding be successful, the City will be required to co-contribute 25% of total cost (both planning and works funding). 

The estimated cost to maintain the jetty ongoing after remediation is approximately $45,000 annually. 

Should the decision be to remove the jetty, the cost to demolish the existing jetty is approximately $130,000. 

Located on the Marlston Waterfront at Bonnefoi Boulevard, Marlston Jetty is in the heart of the City. See location map in image library. 

The funding application will be submitted in September 2025 to proceed with detailed design for the jetty. Should the application be successful, detailed design will be completed in 2026 and further application for construction funding submitted in September 2026, with construction anticipated to take place in 2027. 

The jetty would be accessible to all community members and visitors. Accessibility has been considered in the concept design and should the project proceed, CoDAP will also be consulted in detailed design process.

Marlston Jetty has a significant structural issue where it is currently not adequately secured to the adjacent sea wall to support mooring vessels. An ongoing issue with the jetty is that its design makes it very susceptible to damage from storm events. The substructure of the jetty is also getting more costly to maintain as it continues to age.

Based on specialist marine advice, it has been determined that the entire structure is too low and sits mostly in the tidal water range (immersion zone) rather than the splash zone. This has resulted in excessive timber in the immersion zone and the mass and displacement of large steel sections due to wave action. The Jetty is also structurally dependent upon the seawall and specialist engineering advice has stated that it is possible that the Jetty is contributing to damage to the limestone block seawall. Due to the current design the jetty is also highly susceptible to damage from storm events from a northerly direction. The jetty has been in operable for the majority of the last 6 years and despite renovation works in 2022 is current closed as it is no longer structural sound for watercraft access.  

The overall jetty is closed to the public based on issues with functionality and condition. It is showing signs of the effects of weathering and corrosion and is highly susceptible to damage and inundation during storm events; as evidenced by damage received in 2018 and 2019. The proposed works aim to solve the functionality problems by re-designing and upgrading the jetty to better cope with the ocean environment encountered at this location. This will include moving the jetty structure away from the limestone seawall and adjusting the height to better-handle wave action and provide a more robust interface with the seawall.
