Case Study
As part of a city-wide initiative aimed at reducing flood risk due to coastal storms and sea level rise, recreation areas along Lower Manhattan’s riverfront are being raised eight to nine feet above their historical elevations. A part of the East Side Coastal Resiliency project, Mathews Nielsen Landscape Architects designed these elevated park spaces to work in tandem with a series of floodgates in order to protect neighborhoods and critical transportation infrastructure from catastrophic flooding.
