This 2013 report is one outcome of a multi-year project funded by the US Forest Service and completed in cooperation with the National Association of Regional Councils, with the goal of mapping and evaluating the support system for green infrastructure planning in the US – a system that has changed dramatically over the study period and continues to evolve. Despite the shifting institutional landscape, the purpose of this report remains the same: to provide green infrastructure practitioners and sponsors with a valuable reflection on how the concept emerged, how it has evolved, and where it is heading. In fact, in the same month this preface was written, the EPA released a new strategic agenda for green infrastructure in the US, and the World Resources Institute released an extensive guide to natural infrastructure investment, both of which reflect many of the same observations and recommendations that emerged from this study.
