The Florence Lane Outfall Restoration project was substantially completed on October 30, 2018. The primary goals of this project were to address public safety concerns, stabilize a deeply eroded channel, and improve water quality. The natural channel design techniques used, such as a reinforced bed mix riffle sections and step pools, reduce the flow velocity, provide stability, and enhance water quality along the stream leading to the Chesapeake Bay. The disturbed areas of the site were restored with native shrubs, plants and trees.
