Most places in New York City make it easy to avoid thinking about the rivers, canals, and ocean waters that form an aquatic thoroughfare for the global economy and surround the industrial corridors, office towers, and densely populated neighborhoods where millions of people have settled. This place is not one of them…

She’s the founder of the design firm SCAPE, the director of the Urban Design Program at Columbia University, and the first landscape architect to win a MacArthur “genius” grant.
