The Shetland Court Outfall Restoration project was substantially completed on September 7, 2018. The primary goals of this project were to address public safety concerns, stabilize an eroded channel by using natural stream design techniques, promote the growth of native vegetation, and improve water quality. The natural channel design techniques used, such as a reinforced bed mix riffle sections, step pools and rock steps, reduce the flow velocity, provide stability, and enhance water quality along the streams leading to the Chesapeake Bay. The disturbed areas of the site were restored with native shrubs, plants and trees.
