This Article is adapted from Chapter Three of John R. Nolon, Protecting the Environment Through Land Use Law: Standing Ground, published in 2014 by ELI Press. The book updates and expands on the author’s previous work, describing in detail how localities are responding to new challenges, including the imperative that they adapt to and help mitigate climate change and create sustainable neighborhoods. This Article outlines a comprehensive framework for understanding how traditional local land use authority can be used to preserve natural resources and environmental functions at the community level.
