Rebuilding the West Beach rock wall

See the rebuilding the West Beach rock wall timeline

The West Beach Rock Wall was originally damaged during significant storms in May 2015, and deteriorated further during the May 2016 storms and tidal event.

We're taking responsibility for managing the rebuild of the wall, which will improve the safety of the West Beach Surf Life Saving Club (SLSC) and the damaged Coast Path.

The Rock Wall project is divided into Northern, Central and Southern sections, with this year’s project rebuilding the Central section.

The West Beach Rock Wall Project has a budget of $5.27million. The City of Charles Sturt funded $4.02 million and the Coast Protection Board funded $1.25 million.

Once complete, the project will ensure that the rock wall withstands significant storm events and projected sea level rise. It can act as a barrier and protector for the SLSC, Coast Path, road, car park and homes along Seaview Road for the design life of the wall.

Works commenced in October 2019 and will be complete in June 2020, subject to variations as a result of tidal activity or weather.

Background

There are a number of priorities for the West Beach area.

These priorities include:

  • rebuilding the West Beach Rock Wall
  • exploring solutions to sand management in discussion with the Coast Protection Board
  • the coast path that runs along the coast next to the rock wall
  • the location of the West Beach Surf Life Saving Club which is due for renewal

Sand management

The City of Charles Sturt is committed to protecting not only our assets, but also our coastal environment. Our focus is on caring for the future of our beaches for generations to come.

We will continue to work with the State Government and will monitor West Beach and share this information with the DEW and CPB. We will also continue to advocate for our community’s concerns and reflect our shared desire for a full future strategy to protect the beach, the dunes and our coastline.

West Beach Community Land Management Plan

We have a number of Community Land Management Plans (CLMP) to help us plan the use of community land.

There is a CLMP specifically for West Beach that was created after consultation with key stakeholders and the wider community.

This CLMP has taken into account previous work done by Council at the Coast Path at Tennyson, as well as legal decisions made in relation to the Coast Path at Tennyson.

As a council, we understand that there will be future studies and recommendations about environmental considerations of the rock wall and sand management helping to restore the beach.

Rebuilding the wall

The West Beach Rock Wall rebuild is made up of a number of different elements.

This includes:

  • The existing rock wall is stripped back, retaining rocks that are suitable for reuse, and disposing of the others. The underlying sand dune is then reshaped.
  • Next a geo-fabric is installed to protect the dune. A filter medium is installed on top of the fabric, which allows the water from the waves to flow back to the beach.
  • Together with the salvaged rocks, there is around 16,000 tonnes of new rock imported from a local quarry. These rocks have very specific size, shape, weight and material make up requirements to ensure they all act as designed.
  • On top of the filter layer is the secondary armour. These are rocks are 300 to 500mm in diameter. These help dissipate the wave energy to prevent damage to the dune.
  • Finally on the outside are the larger rocks, weighing between 3 and 6 tonnes each. These take the brunt of the force from waves and storm events.
