After Superstorm Sandy hit in 2012, all kind of ideas were bandied about to combat future fallout from major meteorological mayhem. One proposal would have built a retractable sea wall across the Verrazano Narrows to prevent storm surges from entering New York Harbor. Another called for giant balloons that could be inflated at the mouths of the subway system’s tunnels to prevent them from flooding. Neither seemed especially practical, but now, another proposal is moving forward for what’s essentially one long storm-resistant park running from Battery Park to 23rd Street. It’s name is the East Side Coastal Resiliency Project (ESCR), or more colloquially, the Dryline.
