Yilki Coastal Protection Works
Safeguarding Our Coastline for the Future
Rising tides and storm surges are causing significant erosion and damage along the Franklin Parade coastline at Encounter Bay (also known as Yilki). The City of Victor Harbor is committed to protecting this highly valued area and is taking steps to address the increasing risks to both the natural environment and vital infrastructure.
While emergency works are carried out as needed, longer-term, sustainable solutions are essential. Our Coastal Adaptation Study and Strategy confirms that sea level rise will continue to impact this area well into the future.
Coastal protection has been identified as a key priority in several of Council's Annual Business Plans and Budgets.
We are working in close partnership with the Coast Protection Branch and other key authorities to deliver the best possible outcomes for our community and coastline.
Stage 1: Construction of the Yilki Coastal Sea Defence Wall
Works on Stage 1 of the Yilki Coastal Sea Defence Wall project were undertaken from late April - December 2025. Minor finishing works were also completed in early 2026.
Council engaged CATCON to undertake these works on its behalf.
The project specifically related to the stretch of Franklin Parade between Fell Street and Charles Street in Encounter Bay.
Project Details
The new Coastal Sea Defence Wall is made of two elements – a rock revetment and a concrete wave wall. So far, around 320 metres of new rock revetment and 120 metres of concrete base for the wave wall have been installed.
Stage 1 works also included:
- Pavement rehabilitation and stormwater upgrades
- New and upgraded rock wall armour
- Installation of wave barriers
- Construction of a new shared use path
- Erosion and sediment control measures
- Stepped beach access
- Native planting and landscaping
This major project was primarily funded by Council and supported by grant funding from the Federal Government’s Coastal and Estuarine Risk Mitigation Program, the National Disaster Ready Fund and Coast Protection Board.
Project Benefits
- Immediate protection for community assets such as the Encounter Bikeway and nearby roads
- Long-term resilience for low-lying urban areas against storm surges and sea level rise
