Green stormwater infrastructure (GSI) is not only a key component of a city’s hardworking built infrastructure—it also acts to support social ties within a neighborhood through beautification and place-making. It can improve mobility and safety for street users, as well as visibly reassert the important hydrological and environmental functions of streets.
While both streets and cities come in many forms, GSI can be integrated into many types of stormwater streets in any urban environment. The following street types present recommendations for selecting appropriate GSI elements in selected contexts, and provide guidance for the design and placement of elements to function effectively as both hydrological and social infrastructure. Elements are categorized based on their location in the cross-section
Specific GSI element design is further detailed in Stormwater Elements.
