Every summer, residents along the Gulf of Mexico and Atlantic Ocean coasts brace themselves for the hurricane season. An analysis of storm surges found that 6.5 million single family coastal homes are at risk from flooding during this year's hurricane season, according to property researcher CoreLogic.
Given that oceanfront homes are among the most valuable properties along the coasts and also in the front line of incoming storms, the costs related to such flooding are also high.

Floods from storm surges represent a collective $1.5 trillion in potential reconstruction costs, CoreLogic said.
The forecast for this season is for slightly less storm activity than normal.
"But the early arrival of Hurricane Arthur on July 3 is an important reminder that even a low-category hurricane or a strong tropical storm can create powerful riptides, modest flooding and cause significant destruction of property," he said.
Superstorm Sandy is a prime example. By the time it hit the Atlantic Coast in 2012, it did not even meet the strict definition of a hurricane but still managed to do an estimated $68 billion in damage from the water surge it caused along the coast line. Only Katrina, the costliest natural disaster in U.S. history, cost more.
