Ashburton Tanks Project

Ashburton Tanks Project


The next phase of construction will include deep excavation and micro-blasting to form the footprint of two large drinking water tanks.  This phase of work is scheduled to begin in early September, 2019, and continue for approximately 6 months.  The work will affect traffic patterns on some days – though not every day – between 12:00 p.m. and 3:00 p.m., for about five minutes.  The streets that will be impacted by these construction activities are:

  • 3200-3300 Blocks of North Hilton Street
  • 3000-3200 Blocks of Liberty Heights Avenue

The areas that may see traffic impacts are shown in the map below.

What Residents Can Expect:

  • Construction activities will result in periodic, temporary street closures near Lake Ashburton
  • Traffic control signs will be posted to inform residents when to avoid the Lake Ashburton area due to traffic
  • A moderate amount of noise from construction equipment and micro-blasting operation (Click for a video of similar micro-blasting work, including preventive measures to assure debris is contained)
  • Liberty Heights Ave, eastbound lane sidewalk will be closed; pedestrians are asked to cross the street to use the sidewalk

What Residents Can Do:

  • Seek alternative routes to avoid traffic on N. Hilton St. and Liberty Heights Ave. near Lake Ashburton
  • Follow detours and traffic control personnel

Information about deep excavation and micro-blasting will be discussed at upcoming community meetings being held at 6:00 p.m. Thursday, Sept. 19, 2019, at Ashburton Filtration Plant, 3001 Druid Park Dr, 2nd Floor Large Conference Room.

A reminder:

Please be advised that the sidewalk along the south side of Liberty Heights Avenue, from Hanlon to Dukeland streets, will be closed. Jersey barriers will be installed to protect the work zone from vehicle traffic. Pedestrians will have to walk along the north side of Liberty Heights. This barrier will be in place until the tank construction is completed.  

The next public meeting to discuss construction of the Ashburton Tanks project is at 6 p.m. Thursday, Sept. 19, in the second floor conference room of the Ashburton Water Filtration Plant, 3001 Druid Park Drive. 

To help preserve the high quality and safety of our drinking water system, the Baltimore City Department of Public Works (DPW) has been converting our open-air drinking water lakes to buried tanks. We’ve completed projects in Towson and the Montebello II Filtration Plant, and are in construction on projects at the Guilford and Druid Lake reservoir. Our drinking water will be much safer and secure with these underground tanks, and it will allow us to comply with federal Clean Drinking Water Act regulations.

The work in Hanlon Park will take at least four years to complete (Summer 2018 – Winter 2022), including land preparation (Summer 2018), tank construction (Spring 2019), and restoration (early 2022). Building the park will take about a year longer.

A playground and other park and green space will be built over the tanks in the space north of the lake. The entire project is budgeted for about $137 million. Upon completion, Lake Ashburton will remain as a beautiful freshwater amenity, while 50 million gallons of drinking water is secured safely in two underground tanks, each 434 feet in diameter.

Due to the construction activity, public access to the park will be limited. Most of the entrance and exit for construction vehicles will be on Liberty Heights Avenue at Dukeland Street, keeping construction traffic out of the neighborhood. Funding for this project includes contributions from the State of Maryland and Baltimore County. The contractor, Oscar Renda, is required to remain in compliance with the State and City’s MWDBE hiring goals.

DPW will update this page to provide significant updates, and officials will be in contact with community association leaders and residents during the construction period. Questions may be directed to the Communications and Community Affairs Division, [email protected].
