While the redevelopment of brownfield sites has been the mainstay of public agencies and private developers, this paper argues that in order to promote just redevelopment that encourages participation and targets weak market sites, a community-based approach to brownfield redevelopment should be encouraged. Furthermore, this paper maintains that community development corporations (CDCs) could be the ideal agents to spur community development and address environmental justice concerns through their increased involvement in brownfield redevelopment projects. In order to promote these positions, we first describe this new approach, which focuses on building the capacity of CDCs to meaningfully participate in brownfield redevelopment. We then offer four proposals designed to increase this capacity. We conclude with a discussion of how community-based brownfield redevelopment connects to larger issues of democratic decision-making, environmental justice, and urban revitalisation.
