Cost comparison of infrastructure on greenfield and infill sites

Planning policy in most Australian capital cities aims to divert development from the fringe into established inner urban areas. A fundamental logic underlying this policy of land recycling is that State and Local governments are challenged fnancially to provide appropriate standards of infrastructure and services in greenfeld locations. This paper explores the range of infrastructure provision issues and seeks to identify the actual costs of provision in different locations. Three case studies in metropolitan Adelaide are used to explore the cost factors for developers and government. The study highlights the complexity of analysing the infrastructure cost of different developments which arises from variable record keeping and accounting practices. Nevertheless, the study is able to draw conclusions about the relative costs of infrastructure provision in different locations and reinforces previous studies that have demonstrated the higher costs of infrastructure on the fringe as opposed to infll. The estimated infrastructure costs for the infll development case study at Bowden are shown to be approximately one third that of both greenfield and renewal areas of the Playford Alive project on the urban fringe.
