Abstract

The Magenta Shores development fronts 2.3 km of Tuggerah Beach on a formerly sand mined and landfill site in an urban growth area on the central coast of New South Wales. To increase the natural defences against storm waves and mass sand movements, the incipient foredune was retained and the parallel beach ridge landform was re-established by mimicking natural processes. Analysis of waste and resources led to a coordinated large-scale onsite re-use, recycling and waste management program that reduced landfill, transportation and natural resource requirements. Bitou bush removed from the Coastal Protection Zone was incorporated into golf course soils to improve grass growth. Leachate in the groundwater from the former landfill was diverted away from Tuggerah Lake and re-used in golf course irrigation. Upgrade of the local sewer treatment plant and installation of a public dual pipeline servicing Magenta and the adjoining township satisfied irrigation demands and provided non-potable water for the existing and expanding urban community. The sustainability challenges of the project were met through clear identification of existing environmental risks, application of scientific research, integrated team management and stakeholders’ cooperation.
