The District of Columbia Water and Sewer Authority (DC Water) in cooperation with the National Park Service (NPS) welcome public review and comment on a proposal to rehabilitate the sanitary sewer system in Soapstone Valley Park. Soapstone Valley Park is managed by Rock Creek Park and is located southeast of the intersection of Connecticut Avenue NW and Albemarle Street NW, extending to Broad Branch Road NW. 

Through this project, DC Water would rehabilitate the aging sewer infrastructure within the Soapstone Valley Park sewer system while limiting disturbances to park resources. To ensure public safety, sections of Soapstone Valley Park would be closed to visitors throughout the project. 
The proposed project would involve the following:

  • Clean, line and repair approximately 6,200 linear feet of sanitary sewer pipe.
  • Reduce stream and groundwater infiltration and reduce potential for sewer overflows.
  • Eliminate exposed pipes and manholes to the greatest extent possible.
  • Repair stormwater outfalls that are part of the Municipal Separate Storm Sewer System (MS4) outlet.

Because much of the rehabilitation project will take place in Soapstone Valley Park, DC Water has prepared an Environmental Assessment (EA) to identify and evaluate the potential impacts on natural resources and cultural resources. The EA describes two alternatives, a no action alternative and a trenchless alternative (DC Water’s preferred alternative). 
  
There are three ways to comment on the Soapstone Valley Park Sewer Rehabilitation EA during the 60-day public review period from Tuesday, June 4, 2019, through Friday, August 2, 2019:

  • In person at a public meeting on Wednesday, June 26, 2019, from 6 p.m. to 
    8 p.m. at the Forest Hills of DC Assembly Hall, 4901 Connecticut Avenue NW, Washington, DC 20008
  • Online through the National Park Service’s Park Planning, Environment & Public Comment (PEPC) website at https://parkplanning.nps.gov/soapstonesewer
  • By Mail for letters postmarked by August 2, 2019:

DC Water has completed sludge removal on a section of the C & O Canal between locks 13 and 14, which was used as a bypass to divert wastewater around the collapsed section of the Potomac Interceptor and back into the pipe further downstream. Crews are now constructing an access bridge to this section of the canal to allow soil removal to begin.
