Dense urban infrastructure (70,000+ miles of pipes, many pre-1900) suffers constant failures; nor'easters create coastal flooding; Superstorm Sandy (2012) inundated 17% of the city; high-rise buildings have complex water systems prone to cascading failures between floors
Flood-prone areas: Red Hook, Howard Beach, Canarsie, and South Beach (Staten Island) face highest coastal storm surge risk; basement apartments throughout the five boroughs are at high risk from pipe failures and sewer backup
