New Haven Bioswales
The City of New Haven has installed 286 right-of-way bioswales throughout the city as part of a multifaceted approach to reducing flooding in the downtown area. Right-of-way bioswales are engineered planted areas that are located on sidewalks. They are designed to capture and infiltrate stormwater into the ground that would otherwise directly enter a storm drain. These bioswales were installed as the result of various partnerships and funding opportunities related to flood prevention, localized drainage solutions, combined sewer overflow mitigation, research, and traffic calming projects.

City of New Haven, Dept of Engineering
Project Partners
Urban Resources Initiative, EMERGE Inc., Save the Sound, Yale School of the Environment, and Quinnipiac University, among others.
Monitoring performed by Yale School of the Environment researchers (led by Prof. Gaboury Benoit) have demonstrated that the bioswales have captured 70-75% of stormwater runoff in two locations. These results indicate that the bioswales are highly effective in diverting stormwater and thus, preventing pollution.
