Dredged Material
Management Program

Dredging makes it possible for some of the largest cargo ships in the world to do business in Baltimore. With innovative thinking, thoughtful investment and careful implementation, dredging also provides material to create beautiful habitats for thousands of species of birds and animals, and places of wonder for people to discover nature.


The Port of Baltimore:
An Economic Engine
for Maryland

The Port of Baltimore is an economic powerhouse for the State of Maryland and the Mid-Atlantic region of the United States. Located over one hundred miles up the Chesapeake Bay from the Atlantic Ocean, it is one of only a few East Coast ports with the depth and infrastructure to accommodate some of the world’s largest container ships. In order to keep pace with the large scale of cargo entering the port, thoughtful investment is being made to address the need to update infrastructure. For example, doubling throughput capacity into/out of the port to facilitate double-stacked container trains.


“The Port of Baltimore is one of the most productive ports in the nation and one of Maryland’s top economic generators."

Maryland Governor Wes Moore

That's a Whole Lot of Sediment

Maintaining the shipping channels in the Chesapeake Bay, Baltimore Harbor, and the Chesapeake & Delaware Canal for massive ships is also a massive job. Every year, with help from our partners at the U.S. Army Corps of Engineers, nearly 5 million cubic yards of sediment are dredged from these channels and anchorages just to maintain their current depths and widths.

So what does 5 million cubic yards of sediment look like? Picture the Baltimore Ravens M&T Bank Stadium filled to the brim. Then picture it again. That’s how much sediment we dredge, on average, every single year.

Managing and utilizing the equivalent of two stadiums full of sediment in ways that are good for the Port, good for our communities, and good for the environment is one of the greatest priorities for Maryland Port Administration. Implementing this priority is a core value of the Dredged Material Management Program (DMMP). Three out of five of our placement sites that house dredged material are active today.

The sites housing dredged material include:


Investing in Innovation for the Future

Our innovative approach to dredged material management builds more than award-winning placement sites – it is an investment in the future. Through dredged material management we are supporting stronger local communities and building thousands of acres of wildlife habitat where people can explore, discover, learn, and grow. 

Learn more about fascinating sites like Hart-Miller Island - also a state park, Masonville Cove - the first Urban Wildlife Partnership in the country, and Poplar Island - an international model for the beneficial use of dredged material or our other placement sites.

Building the Future Together

One of our key strengths is the partnerships we have built with our wide array of stakeholders. Our dedicated staff, community members, committees, nonprofit organizations, scientists, regulators, policy makers, port businesspeople, and local residents have all contributed to our success today and have important roles in informing our plans for the future.
