More than 4, additional plants will be planted on the Semaphore South dunes later in Concurrently sand will continue to be collected from the Semaphore South breakwater at Point Malcolm and moved to West Beach as part of the regular beach replenishment program. Project Manager Securing the Future of Our Coastline, James Guy, said the Department for Environment and Water manages the metropolitan coastline for the community to enjoy sandy beaches and to provide protection from storms.

Another branch spur, built in , ran in a northerly direction from just west of the kiosk to a great fenced area for the baths.
The baths were divided into two sections — one for males and the other for females — for in those days mixed bathing was not permitted. From Largs Bay Jetty down as far as Glanville Hall, there were notices every few hundred feet along the beach, indicating Ladies in one direction and Men in the opposite.
At the entrance to the jetty was a huge notice at least four feet square stating that bathing was permitted from the jetty except between the hours of 11pm and 6am. This was probably because nobody bothered to wear bathers swimming at the end of the jetty during those hours. Storms often brought seaweed ashore in the form of great islands capable of carrying a person.
A severe storm in May caused widespread coastal erosion throughout South Australia. At Semaphore South, much of the dune and its vegetation was lost. Major replenishment works to restore the dunes and protect the area from further damage by storms was undertaken in Sand was moved from north of the Largs Bay jetty, where there is a large accumulation to rebuild the eroded dunes at Semaphore South between Arthur Street and Hart Street.
More than plants were planted and drift net fencing was installed to stabilise the dunes. Sprinkler irrigation was installed to help the plants establish and grow and also help to reduce wind-blown sand. This timing ensured that a buffer was in place to protect the area for winter when storms causing further erosion are more likely.
Stabilisation has followed well established methods using drift net fencing and revegetation refer for example to the Tasmanian Coastal Works Manual for further information. The project to re-establish the Semaphore South dunes using sand from north of the Largs Bay jetty was a one-off trial project.
However, as has occurred in the past, the seaward part of the Semaphore South dunes will erode from time to time and will require periodic replenishment with smaller amounts of sand to maintain the foredune area that is directly exposed to coastal processes.
The dunes continue to be monitored and will be periodically replenished with sand from the north of the Largs Bay jetty. See: Why have some of the beach access tracks been raised in height? The department has been working closely with the City of Port Adelaide Enfield and community representatives on the project. Community input was sought in March on the proposal, and the majority of feedback received supported the work to restore the dunes at Semaphore South.
