Relocate and Replace Washington Suburban Sanitary Commission Sewer Line at Still Creek in Greenbelt Park EA

The National Park Service (NPS), in cooperation with the Washington Suburban Sanitary Commission (WSSC), is proposing to relocate a sanitary sewer pipe within the Greenbelt Park (the Park), a NPS unit under administration of National Capital Parks-East located in Prince George's County, Maryland.

The purpose of this project is to relocate a 400-foot section of a 21-inch sanitary sewer pipe located along Still Creek within the Greenbelt Park. Specifically, the NPS will issue WSSC a special use permit (SUP) for construction and access to relocate the sewer line and a right-of-way (ROW) permit for the ongoing maintenance of the utility infrastructure. The relocation is needed due to the poor condition of the pipe and to accommodate a new bridge over Still Creek currently under construction.

Previously, the NPS, in cooperation with the Federal Highway Administration (FHWA), prepared an Environmental Assessment (EA) that analyzed the impacts of proposed improvements to rehabilitation of the Park's roadways, parking lots, guardrails and drainage structures. The EA also looked at the replacement of an existing double culvert with a bridge over Still Creek. A finding of no significant impact (FONSI) was prepared for this project and executed in 2018.
