It’s been seven years since Superstorm Sandy brought the city that never sleeps to a grinding halt. High tide and storm surge—the pile of water that built up in front of Sandy as she moved up the coast—combined to bury lower Manhattan under 13 feet of water. Across the five boroughs, subways, highways, and parking garages flooded; homes and businesses were destroyed, and 53 people died. It is estimated that Sandy caused $19 billion in economic damages in New York City alone.
