New York

As part of the NYC Deparment of City Planning’s ongoing climate resiliency initiatives, the city is working with coastal communities to update the special zoning regulations that apply in the 100 and 500 year floodplain. The term "100-year flood" is used to simplify the definition of a flood that statistically has a 1-percent chance of occurring in any given year. Hurricane Sandy was a 300-year storm. In this new paradigm, the city is hoping to make regulations promoting flood-resistant design permanent to ensure that neighborhoods are more resilient to flooding and climate change.
