The city of New York has learned the hard way. After Supertstorm Sandy, the city is evaluating building code changes, improving their electrical grid and make sure critical emergency facilities are ready to withstand massive natural disasters. At least a quarter of a billion dollars will be used to improve their electrical grid and gas systems to withstand a category 2 hurricane. In addition to those efforts, the city is planning on reviewing all berms, levees and could be building a stronger coastal barrier. Building officials could probably require new developments to be designed at higher elevations and some facilities could be asked to create their own power-generation systems.
