The National Park Service (NPS) prepared an Environmental Assessment (EA) to examine alternative actions and environmental impacts associated with the proposed Soapstone Valley Sewer Rehabilitation Project. The District of Columbia Water and Sewer Authority (DC Water) is responsible for operating and maintaining the existing sanitary sewers serving the District of Columbia (DC or District), and the proposed project identifies multiple sanitary sewers throughout DC Water's collection system that have exceeded their design life and are in need of rehabilitation within the Soapstone Valley sewer system, primarily located within Soapstone Valley Park. Soapstone Valley Park (United States Reservation 402) is 24.59 acres in size and is administered in part by Rock Creek Park, a unit of NPS.
