Rebuilding the West Beach Rock Wall

West Beach Rock Wall

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. The City of Charles Sturt is taking responsibility for managing the rebuild of the wall, with the West Beach Rock Wall Project improving the safety of the West Beach Surf Life Saving Club 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 - Central Section has a budget of $5.27million, with $4.02m funded by the City of Charles Sturt, and $1.25m funded through the Coast Protection Board.

Once complete, the project will ensure that the rock wall will withstand significant storm events and projected sea level rise and 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 2018 and will be complete in June 2019, subject to variations as a result of tidal activity or weather – the timeline to the right shows in details what works will be carried out, and will be updated throughout the course of the project.

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, and the location of the West Beach Surf Life Saving Club, which is due for renewal. These priorities do impact each other, and the City of Charles Sturt has been liaising with all stakeholders to ensure sound outcomes are achieved.

The West Beach Rock Wall is an existing structure that has been damaged through storm events. This damage has caused instability of the wall, and surrounding beach access ramps and the Coast Path. It is imperative that the wall is rebuilt to ensure the existing damage can be fixed, and infrastructure is protected into the future.

Sand Management

It is acknowledged that the beach has become significantly depleted at West Beach and to that end the Council and West Beach Parks co-funded a study by Danish Hydraulics Institute (DHI) to investigate the causes and solutions.  As a consequence of the Study, the State Government, through the Coast Protection Board, announced in September 2018 that it will fund $1million of sand carting, bringing sand from Semaphore beach back to West Beach.

West Beach Community Land Management Plan

The City of Charles Sturt has a number of Community Land Management Plans (CLMP), which are documents prepared in consultation with the community that provide direction about the use of Community Land.

These Management Plans enable Council to develop and manage land that it owns or is under its Care Control for use by the community. The vast majority of Community Plans relate to land used for open space and recreation purposes.

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 of the West Beach area, and future recommendations about the environmental considerations of the rock wall, and sand management aimed at helping restore the beach. Due to the high risk of storm damage to the surf club, the danger to people using the damaged path and the need to return access to the beach via the staircases near the rock wall, the City of Charles Sturt’s priority is to rebuild the rock wall.

Therefore, as part of the consultation for the CLMP - West Beach, we sought legal advice about our processes and the content of the plan itself. We are confident that the CLMP addresses the key elements from Supreme Court decision about the Tennyson Coast Path. You can read about the West Beach CLMP in a recent report to Council.

The City of Charles Sturt recognises that there a number of key stakeholders and the wider community interested in the West Beach CLMP and the rebuilding of the West Beach Rock Wall.

Rebuilding the Wall

The West Beach Rock Wall rebuild is made up of a number of different elements broadly described as follows:

  • The existing rock wall is stripped back, retaining those 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 generally 300-500mm 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.

The contractors appointed to undertake the works anticipated progressively working from north to south and completing approximately 50 metres of wall every six weeks.

Renewing West Beach Road

The City of Charles Sturt is also leading work along West Beach Road. The new road layout will help to improve safety for all users of this important road, which provides access to tourism and sporting venues and events in the West Beach Precinct. This work began in October 2018 and will be complete in June 2019. Both projects are running concurrently.
