Philadelphia District Regulatory Branch

The Philadelphia District was established in 1866 to manage the water resources of the Delaware River Basin, and of the Atlantic Coast from New Jersey’s Manasquan Inlet to the southern boundary of Delaware. We serve more than nine million people across portions of Delaware, Maryland, New Jersey, New York and Pennsylvania.

The U.S. Army Corps of Engineers Regulatory Program began in 1890 with the responsibility of protecting and maintaining the nations navigable waterways. As a result of changing public needs and evolving policy via new laws and court decisions, protection has been extended to all waters of the United States, including many wetlands.
