Adelaide beach works

 

Update September 2021

Strong winds, large seas and significant rainfall over winter 2021 has caused erosion of beaches and sand dunes at locations such as West Beach, Semaphore South and elsewhere along the coast. The state government’s beach replenishment program is critical to providing protection to infrastructure from these storm events. The department continues to work to replenish affected areas.

Sand is a finite resource - it needs to be shared equitably along our coastline so we can all enjoy Adelaide's stunning coastline.

The state government announced that up to 250,000 cubic metres of sand from land-based quarries will be delivered to West Beach in 2021. 

This is part of the state government’s $48.4 million Securing the Future of our coastline project, which includes a commitment to deliver a large quantity of sand (up to 500,000 cubic metres) to West Beach from outside of Adelaide’s beach system

Using quarry sand for the first phase of the mass replenishment will ensure that large volumes of sand are delivered to West Beach before the end of the year. 

Delivery of the quarry sand commenced in August 2021. Sand is being delivered to the dunes at West Beach Parks via the Adelaide Sailing Club beach access ramp. 

Community safety 

Beach users are asked to take extra care on the beaches while works are underway and stay off the dunes.

Glenelg North beach replenishment

Works: Sand movement works from West Beach harbour to Glenelg North
Timing: Works commencing in week of Monday 18 October 2021
Contact: DEWCoasts@sa.gov.au or phone 8124 4928

Works to replenish the beach at Glenelg North are being undertaken in October/November 2021.

Sand is being collected from the area just south of the West Beach harbour and moved by trucks along the beach to the foreshore south of Burns Street, Glenelg North.

The sand will help to raise the beach level along the narrower stretch of Glenelg North beach. 

The removal of sand will help prevent excess sand moving around the harbour breakwater and into the harbour where it would otherwise need to be removed with a dredge.

The works are expected to be completed in November 2021 with the main operating hours being between 7.00am to 5.00pm, Monday to Friday (subject to weather conditions).

Sand movement from Semaphore and Largs Bay to West Beach and Henley Beach South

Works: Sand movement from Semaphore and Largs Bay to West Beach and Henley Beach South
Duration: Periodically 2-3 times per year (autumn and spring)
Autumn/winter works were undertaken from May - August 2021
Contact:DEWcoasts@sa.gov.auor phone 8124 4928

The Department for Environment and Water continued its beach replenishment program for West Beach with sand moved from Semaphore.

  • Works commenced in the week of 17 May 2021 and were completed on 13 August 2021. Sand was moved from the Semaphore South breakwater and from between the Semaphore and Largs Bay jetties to replenish West Beach. 
  • Sand was not moved to West Beach from north of the Largs Bay jetty as part of the autumn/winter 2021 works program. However sand from north of the Largs Bay jetty is used to replenish dunes at Semaphore South (see: Semaphore South replenishment)

Sand is normally moved in spring to provide sandy beaches for summer and again in autumn to protect the coast through winter. In response to community feedback in Semaphore as a trial, the department moved sand to West Beach over winter. 

The department regularly meets with community representatives and council to help guide the Semaphore sand movement works.

Semaphore South dune replenishment 

Works: Replenishment of dunes at Semaphore South

Replenishing the dunes between Noonies Café and Hart Street, Semaphore South is required periodically. This was undertaken in late March/early April 2021, June/July 2021 and again in August 2021 following high tides and severe weather that caused further erosion of the dunes.

The dunes continue to be monitored and will be periodically replenished with sand from the north of the Largs Bay jetty.
