Cost comparison of infrastructure on greenfield and infill sites

Abstract 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 financially to provide appropriate standards of infrastructure and services in greenfield 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 infill. The estimated infrastructure costs for the infill 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.

Renewable Energy: Urban Centres Lead the Dance in Australia?

Australia provides great potential as a case study for renewable energy governance. It is a large continent with a comparatively small and highly urbanised population. It possesses enormous mineral wealth and is a major exporter of fossil fuels, but it also has huge potential for the exploitation of renewable energy. Politically, it is a country divided between those who support large-scale exploitation of fossil fuels and those who advocate that the nation should grasp the opportunity of its rich renewable resources to become a world leader in this field. The potential for renewable energy development has been recognised in some areas, with large-scale wind energy development in particular. But the great distances between energy sources and users suggest that the urban centres themselves should be examined as sources of renewable energy. Governance is complex, with three levels, Federal, State and Local, each exercising power and capable of influencing energy concerns. The key question which is addressed in this chapter is, in a regime with multiple layers of government, at what level is renewable energy development best promoted? We address the politics of energy in the context of Australia’s economy and governance arrangements. Drawing data from previous research carried out by the authors, we examine the potential of urban areas to generate and supply their own power from renewable energy. Using Hammer’s (2009) capacity to act theory we examine the capacity of local government to develop urban renewable energy. We seek to identify hesitations towards RE adoption in all levels. A critical question concerns whether bottom-up or top-down action is preferable.
