Duck Hill on the Rise - Green Infrastructure case study in Duck Hill, Mississippi
The Southeast Sustainability Directors Network funded a project in the small town of Duck Hill, Mississippi, (population of approx. 1,300) to implement green infrastructure for repetitive flooding issues in the community. The Southeast Sustainable Communities Fund provided $300,000 to support flood water mitigation and creek restoration, community engagement and empowerment, youth conservationist training, and “creative place making.” The Fund supports local communities in the southeastern U.S. to advance climate adaptation and social equity in local government policy, plans or programs.
Due to the severity of the flooding, the project design team chose to implement a combination of “grey” and “green” stormwater infrastructure. As described in the case study, the installation is comprised of bioswales, perforated pipes, biodegradable fabric, rock and gravel, and rain gardens that can absorb and filter thousands of gallons of rainwater before syphoning it into one of the larger paved drainage ditches for a more controlled flow out of town and into a nearby creek.
The installation has proven to properly manage flood waters, and the local community considers the project an immediate success. In February 2019, Duck Hill had sixteen inches of rain in four days. The water rose quickly, but with the new drainage system, it receded within half an hour - rather than over hours or days.
The Duck Hill community worked together to reduce stormwater flooding and damage – and plans to keep working together and advocating for equitable climate adaptive investments in their communities.
