This project was identified for stream restoration and basin enhancement as part of the overall effort to improve water quality on the Government Center campus. Staffs of the Stormwater Planning Division initiated the design of the project in July 2019.
The project area is generally identified as a floodplain and Resource Protection Area. The stream is fed from a watershed that includes Pennino and Herrity buildings, the Public Safety Headquarters, the Fairfax Corner shopping area and the Government Center parking lots. This largely impervious watershed has caused stream degradation and sedimentation of the ponds.
The primary goals of the restoration are:
Mitigate the stress of runoff and resulting erosion of the stream
Prevent sediment and nutrient pollution in downstream waterways including Difficult Run, the Potomac River and Chesapeake Bay
Enhance the riparian vegetation of the Resource Protection Area
Provide water quality benefits by dredging the ponds to provide stormwater management while preserving the natural aesthetic and recreation (fishing) benefit
The project is located north of the Government Center, bounded on the upstream by Government Center Parkway and downstream by Monument Drive. The project is in the Braddock Magisterial District.
Improvement of water quality through the removal of Nitrogen, Phosphorous and Total Suspended Solids.
The project design is expected to be completed by September 2020.
What to Expect
Over the next several months, flagging and survey markers will be visible throughout the project area. Contractors and staff will primarily be on foot and wearing high-visibility clothing. This project is not currently funded for construction. Future construction work would include truck traffic entering the site through the Government Center parking lot. The typical work week is Monday through Friday, starting after 7 a.m. Note that at some periods during construction, work may occur on weekends. Deliveries on those days will occur after 9 a.m.
