(Washington, DC) – DC Water is performing construction activities on First Street, NW as part of the McMillan Stormwater Storage Project. Concurrent with this work, there will be inspection of sewers on North Capitol Street. This will be done as a follow up assessment of the integrity of existing area sewers.

From Tuesday, January 21 through Friday, January 31, weather permitting, there will be closure of one northbound travel lane on North Capitol Street between Girard Street and Irving Street. Daily work hours for this portion of work will be from 9:30a.m. until 3:30p.m., Monday through Friday.

Important Information:
* Temporary traffic signs will be set up throughout the area to alert motorists to the upcoming traffic changes.
* Some traffic delays within the vicinity of the work zones are anticipated.
* Noise levels will be closely monitored during construction.

Project Details
DC Water will construct two underground structures to divert stormwater into a temporary holding tank within the McMillan Sand Filtration Plant and existing trunk sewer. The two diversion structures at North Capitol Street and First Street will work together with the retention basins along Irving Street to delay approximately 4.5 million gallons of stormwater from reaching the Bloomingdale and LeDroit Park neighborhoods during heavy rainfall events.

This is a two-phase project. The first phase, completed in 2013, included removal of sand from two tanks. The second phase of the project is currently underway, and includes work on North Capitol Street, First Street and Irving Street.
