The Dryline

Urban flood protection infrastructure

The Dryline (BIG U) addresses New York City’s vulnerability to coastal flooding with a protective ribbon in Southern Manhattan. The 12 km-long infrastructural barrier incorporates public space with the high-water barrier doubling as parks, seating, bicycle shelters or skateboard ramps.

Embankments add green areas and spaces beneath elevated roadways are built out with pavilions for public use. In an emergency, the shutters close forming a floodwater barrier.
