In 2018, Hamlin Street NE installed bioretention systems managing 2.6 acres in Washington, DC. 8 years later, they retain nearly 20,000 gallons per storm, improving water quality in Hickey Run

Hamlin Street bioretention systems are quietly changing how Washington, DC, handles stormwater. Two green infrastructure systems can retain nearly 20,000 gallons during a storm. They manage runoff from about 2.75 acres near the Hickey Run watershed. The project slows polluted water before it reaches local waterways. It also shows how one city street can become part of a larger water-quality solution.
