Construction of the Masonville Dredged Material Containment Facility began in 2007 and the site began receiving dredged material in 2010. Designed to contain sediment from the Baltimore Harbor, Masonville is located on the Southern Shore of the Patapsco River in Baltimore City.
The total footprint of the Masonville facility covers 141 acres, including a dike that enclosed 127 acres of open water. The annual placement capacity is 500,000 cubic yards of sediment, with an estimated total capacity of 15 million cubic yards. Compared to Hart-Miller Island and Poplar Island, this is a small placement site. The end use of the site is anticipated to be an expansion of the Masonville Marine Terminal.
The construction permits for Masonville require the Port Administration to complete significant mitigation activities, both adjacent to the site and within the upstream watershed. The Port Administration worked with the surrounding communities and other stakeholders to select a mix of projects that included important enhancements for the adjacent Masonville Cove, including a new environmental education center, as well as off-site mitigation projects. The project received strong community support as it worked its way through the permit process.
