Central Corridor Stormwater and Green Infrastructure Planning Project

Saint Paul, Minnesota

At the City of Saint Paul’s request, SRF’s team of water resource design experts and a public artist developed a unique stormwater and green infrastructure plan to assist the Cities of Saint Paul and Minneapolis in meeting their goals for transit-oriented development (TOD), new parks and open spaces, and enhanced livability along the new METRO Green (Central Corridor) Light Rail Transit line, which will link downtown Minneapolis and downtown Saint Paul, primarily following University Avenue.  Green infrastructure is a stormwater management technique that mimics natural processes and provides environmental benefits. Shared, stacked-function refers to situations where the green infrastructure serves more than one parcel (public and/or private) and also provides economic, environmental, or social benefits.

The project included both technical studies and policy development.  The feasibility of implementing shared, stacked-function green infrastructure along the Central Corridor was investigated as a way to meet stormwater treatment requirements, while also facilitating increased redevelopment densities.  The SRF team worked with a stakeholder advisory committee and conducted developer focus groups to better understand the full range of issues and opportunities associated with shared, stacked green infrastructure.  The outcome of the project was a site development guide. Funded through a Corridors of Opportunity grant and a Mississippi Watershed Management Organization grant, the project will serve as a model for other TOD corridors in northern climates.
