Pier 57, New York City
Manhattan’s First Swimmable Beach in Generations
Pier 57 reimagined New York’s relationship with the Hudson River by bringing a beach back to Manhattan for the first time in generations. The project transformed obsolete infrastructure into a living interface between city and river, producing clean water, renewable energy, habitat, and public space. What was once an industrial edge became a place where people could once again touch the water, experience the ecology of the Hudson, and reconnect with the river as a civic landscape.
Commissioned by Google and developed with The Living, Natural Systems Utilities, Verdant Power, and Atelier Ten, the proposal transformed Pier 57 into a living interface between city and river. By capturing and treating the local Combined Sewer Overflow (CSO), the project reduced potable water demand by 75%, generated 105 kilowatts of tidal energy, and harvested 150 tons of free cooling from the pier’s historic caissons while creating a habitat of more than 150,000 mussels that filter the Hudson while acting as living environmental sensors.
150,000 Mussels Filtering 750,000 Liters of Water Per Hour
The beach was made possible by a new ecological infrastructure hidden within the pier itself. Combined sewer overflow was captured and treated through natural and engineered filtration systems, while mussel colonies continuously cleaned river water, tidal currents generated renewable energy, and the historic caissons were repurposed as a thermal battery for building conditioning.
Wired with environmental sensors, the mussel colonies became non-human lifeguards for the city, communicating the health of the river and signaling when the water was safe for public swimming. Together these systems transformed waste streams into resources and positioned the pier as a catalyst for a healthier Hudson Estuary.
