The Politics Behind the Spatial Planning of Green Infrastructure in U.S. Cities

This research project is part of a larger study of green infrastructure in urban planning and sustainability initiatives in cities across the U.S. Within the past few decades, the topic of sustainability has been at the forefront of city planners’ minds as cities grow, there is new or redevelopment, and the threat of climate change and future climate variability increases. Green infrastructure is one increasingly popular urban sustainability strategy, which is widely promoted for its ability to provide multiple benefits. This multi-functionality translates into ecosystem services and possible disservices for a local community and the city as a whole. This research project examines 120 planning documents from 19 U.S. cities to examine whether the services cities say they expect green infrastructure to provide, or the rationale, match with the criteria used to determine where green infrastructure is sited. For this project, we ask: what are the rationales that cities provide for developing green infrastructure and what are the criteria cities are using to determine where to site it? We find that certain rationales, or benefits, are claimed without corresponding and specific siting criteria to substantiate how these benefits will be achieved, while other benefits, like those related to stormwater management, are prioritized over other potentially important benefits.
