    I think the whole section, but in particular to ensure the cycle path to Fremantle is maintained. Great for exercise, family and community activity. Beach access is a must. With all the high rise near South Beach being developed, perhaps some of the developers could contribute both financially and with innovation

      Thanks so much for taking the time to share your input. Your comments have been collated alongside those from the wider community. Key findings from the community consultation will be provided to engineering consultants who will assist with the development of potential solutions for erosion control at this location. We’ll be seeking your feedback on the engineered options once they have been developed. Jon – Project Team

    Contact bgc precast at naval base. They have developed a flexible erosion mat. That with stands cyclones. Not sure on cost. But what is money when the cost is nature.

    The erosion problem is serious and the CoC is commended for taking action to urgently to fix the problem. I suggest that a sand transfer pipe be installed, similar to that installed at Port Coogee development, to take sand from the north of the Catherine point groyne to replenish the erosion on a regular basis.Sand may also be available from groynes further north. Engineering consultants should be consulted on the proposal.

      Thank you for taking the time to share your feedback, your input is appreciated. Your feedback has been noted and collated with the feedback from the wider community. The key findings from the community consultation will be provided to Engineering Consultants who will aid in the development of some suitable options for erosion control at this location. The City will be seeking further feedback from the community on the potential options developed by the engineering consultants later this year. Jon – Project Team

    The erosion problem increased dramatically when the groyne at the northern end of CY O'Connor Beach was extended. It's hard to imagine that there isn't a causal link between the groynes and the erosion/sand build up. So, can we have modelling of the effects of removing/reducing the groynes?

      Hi Siobahn, Thanks so much for your feedback and interest in this project. The City has engaged engineering consultants who have specific expertise in coastal erosion and coastal projects to work with us on this project. Engineers advise that the removal or shortening of Catherine Point groyne is likely to increase transport past the groyne, predominantly to the south. This would result in a significant re-alignment of the shoreline and substantial erosion of the section of shoreline north of the current groyne. This is likely to put the car park and foreshore at the Rollinson Rd entry at risk. Jon, Project Team

    What impact has the extension to Catharine Groyne made to the sand erosion problem?

      Hi Peter, thanks for your question. The shoreline has been eroding since around the mid to late 1990s. The Catherine Point groyne was reconstructed in 2012/13 however it was not extended. The reconstruction of the groyne therefore had minimal impact on the sand erosion problem. Jon, Project Team
