Water: Green Infrastructure
EPA is assessing the performance of green infrastructure practices in several communities. Researchers are examining the impacts of green infrastructure not only on water quality and aquatic ecosystems, but on social and economic outcomes as well. EPA is particularly interested in the potential for green infrastructure to revitalize struggling communities while advancing water quality goals. Learn more about EPA research on green infrastructure.
For the last 100 years, the Lick Run stream in Cincinnati was put into a pipe that combines storm flows and sewage. During even small storms, the pipe spills its polluted mixture into the nearby Mill Creek where downstream water quality is compromised.
A recent goal of EPA and the Metropolitan Sewer District of Greater Cincinnati is to remove stormwater discharge from the pipe and return the Lick Run to a state that flows freely to the Mill Creek. As part of this goal, EPA researchers are collaborating with the local sewer district to monitor and adjust several green infrastructure early success projects that are designed to take stormwater out of the combined sewer and put it to good use elsewhere.
This pilot project is part of a larger adaptive management approach to incorporate green solutions into the Kansas City CSO long-term control plan. The project involves local and regional efforts to provide the “basis-for-success” of the implementation of green solution infrastructure and stormwater management at the neighborhood, watershed, and regional levels. The project will demonstrate the methodology, including model support, for identifying where and how green solutions will be implemented within Kansas City.
