May Meeting To Highlight HoCo's North Tunnel Project That Begins Construction This Summer

HOWARD COUNTY, MD — Starting this summer, work will begin on the north tunnel project, which is a key element in the Ellicott City Safe and Sound plan. Residents can learn more about the project and provide comments at a meeting May 23 at 6 p.m. at the Roger Carter Recreation Center, 3000 Milltowne Drive, Ellicott City.

Weather permitting, the project should wrap up in late 2027.

The north tunnel is a 5,500-foot-long, 18-foot-in-diameter tunnel with its upstream end located on the north side of Frederick Road, approximately 500 feet east of Papillon Drive, and its downstream end located at the Patapsco River shoreline, approximately 500 feet north of Main Street.

The north tunnel is one of two water conveyance projects in the Ellicott City Safe and Sound plan. The project will collect storm water at several locations and transport the water through a series of subterranean conveyance elements to the tunnel, discharging water into the Patapsco River. The tunnel will have the capacity to move approximately 26,000 gallons of water per second underneath Ellicott City and away from Main Street.

All components of the Ellicott City Safe and Sound Plan, which can be found at ecsafeandsound.org, also include:

• Seven major water retention and water conveyance projects, including the tunnel and the ponds being constructed
• Enhanced stream cleaning
• Tone alert warning system and signage
• Drainage improvements throughout the watershed
