A dune was constructed to house a biofiltration unit. Increased volume of the dune to prevent storm surges is a co-benefit of this project. The project was funded by Mornington Peninsula Shire, Melbourne Water and the Victorian Department of Land, Water and Planning (via the Port Phillip Bay Fund).
