Brownfield revitalization can support community efforts to become more resilient to climate change impacts by incorporating adaptation and mitigation strategies throughout the brownfield cleanup and redevelopment process. This manual will help communities think about climate mitigation, adaptation, and resilience in the context of brownfield cleanup and redevelopment. This includes consideration of projected climate change and potential impact on vulnerable populations when performing brownfield site assessments, evaluating cleanup alternatives, and planning for redevelopment. Early evaluation facilitates forward-looking decisions related to land use, zoning and building codes that increase resiliency. Communities are also encouraged to reduce carbon, greenhouse gas sources, and emissions through sustainable mitigation throughout the cleanup and redevelopment of brownfields and in the reuse of these sites. This manual also will help brownfield communities better understand the range of climate change mitigation and adaptation strategies that can be applied at and around brownfield sites. It can serve as a resource for communities, grantees and government entities looking to assess, clean up and revitalize brownfields in a way that increases resiliency. Finally, this manual can serve as a resource to users seeking additional information about increasing resiliency through brownfield revitalization. There is an annotated listing of informational resources and tools at the end of the document.
