Florida is the top state in U.S. most at-risk of flooding due to both climatic and geographic reasons. Florida suffers from both river and coastal floods. And being located in the subtropics makes Florida vulnerable to tropical and subtropical cyclones, also known as hurricanes. From 2000 to 2013, 63 hurricanes or tropical storms have struck Florida and caused over $64 billion in damage collectively. Florida’s terrain is also relatively flat so it’s harder for water to drain.
