In 2011, Klaus Jacob of Columbia University released a report (with the image above) detailing the effects of a 100-year storm on the NYC transit system as part of a larger study on climate change.
Today, MTA Chairman Joseph Lhota called the effects of Hurricane Sandy the “worse than the worst case scenario.”
According to Klaus’ report, a storm like Sandy could effect the subway system so much that it may take up to 21 days to get it working at 90 percent functionality. However, “if all potential damage is considered, Jacob and colleagues warn that timeline could increase to several months, and that permanent restoration of the system to the full revenue service that was previously available could take more than two years.”
A scary prospect to say the least.
