Scrap the 100-year storm--cities may need to prepare for the 500-year storm after Hurricane Sandy, some experts say. As authorities hustle to restore power, pump out subway tunnels, and alleviate gas shortages in New York City, some say that after the historic storm, mere recovery may not be enough. To prevent a Sandy-like disaster again may require putting in place protections for the next monster storm. With the total bill for Sandy recovery expected to be in the tens of billions of dollars, New York and similarly vulnerable cities may not be able to afford not to invest in precautionary measures.
