MCMILLAN CONSTRUCTION COMES TO FIRST STREET

November 27, 2013

(Washington, DC) – DC Water is set to begin construction on First Street, NW as part of the McMillan Stormwater Storage Project.

Beginning Monday, December 2, 2013 through mid January 2014, weather permitting, crews will begin preparations to construct a diversion chamber at the southwest corner of Channing Street, NW that will connect to the future First Street Tunnel.

This project supports the Northeast Boundary Neighborhood Protection Project and the diversion chamber will assist in delaying approximately 500,000 gallons of stormwater from reaching the Bloomingdale and LeDroit Park neighborhoods during heavy rainfall events.

Important Information:
* Monday, December 2, 2013 through Monday, December 9, 2013 –First Street, NW between Channing Street and Michigan Avenue will be closed to southbound traffic. One lane will remain open for northbound traffic only.
* Monday, December 9, 2013 through mid January 2014 – There will be partial and full road closures on First Street, NW between Channing Street and McMillan Drive.
* Construction operations for all partial road closures will be from 7:00am to 7:00pm, Monday through Friday; construction operations for all full road closures will be 24 hours, Monday through Saturday.
* 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.
* Sidewalk detours will also be implemented.
* There will be an increase in truck traffic.
* Noise levels will be closely monitored during construction.
* To avoid traffic delays, North Capitol Street may be used as an alternative route for travel on First Street, between Channing Street and Michigan Avenue.

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.
