The growing frequency and severity of flooding in NYC and other coastal cities pose significant risks to infrastructure, public safety, and economic stability. Rising sea levels and more intense storms are expected to increase the likelihood of severe flooding, particularly in low-lying, densely populated areas. The U.S. Gulf and Atlantic Coasts are especially vulnerable, with 30% of counties in these regions already at high flood risk. The financial toll of flooding in the U.S. has exceeded $200 billion since 1980, with damages expected to rise as climate change progresses.
