The National Aquarium in Baltimore has opened the National Aquarium Harbor Wetland, a 10,000-sf floating wetland that mimics the Inner Harbor’s original Chesapeake Bay tidal marsh habitat. Located between Piers 3 and 4 on Baltimore’s Inner Harbor, the $14 million project features more than 32,000 native shrubs and marsh grasses.
With Ayers Saint Gross as the architect of record and Whiting-Turner as the construction contractor, the project is based on sustainable innovations developed by the Aquarium’s conservation and exhibit fabrication teams. At the project’s start about a decade ago, Studio Gang participated as the original concept architects.
“Harbor Wetland is the culmination of 12 years of research, innovation, and determination,” Aquarium president and CEO John Racanelli said in a press statement.
Ayers Saint Gross worked with the National Aquarium to design a sustainable, high-performing floating wetland intended to restore natural habitats and improve biodiversity and water quality. The project aims to reverse years of environmental degradation while creating a renewed, thriving ecosystem. The design features layered topography, with planting surfaces at tiered elevations to promote a variety of microhabitats and attract a greater diversity of species to the area.
Free and open to the public, the constructed wetland serves as a floating classroom for the community. Interpretive signage allows guests to learn about the wetland, the species drawn to it, seasonal changes, and the surrounding harbor.
Featuring docks, walkways, and shade cover, the habitat is composed of recycled plastic matting planted with native tidal wetland shrubs and grasses, whose roots will grow down into the water. This provides microhabitats for native species while drawing nutrients and contaminants from the water. Coated with a UV protectant for durability, the matting is fixed to a system of air-regulated pontoons that allow for adjustable buoyancy of the wetland, offsetting weight gain from growing biomass.
Compressed air is pumped into the channel to circulate water through the wetland’s shallow channel. Bubbles from the compressed air release oxygen into the water—benefiting aquatic species and keeping water moving through the wetland as it would during tidal changes in a natural tidal marsh.
“We hear so much negative talk about Inner Harbor water quality, but there is life in this water and there always has been,” Jack Cover, the Aquarium’s general curator, said in the statement. “My hope is that when people see the life this wetland attracts, from tiny microorganisms to fishes, crabs, water birds, and even small mammals like muskrats and otters—all of which we’re already seeing here—they might reconsider our local waterways and perhaps even take better care of our natural surroundings.”
