#4: New Orleans, Louisiana

Six years after Katrina pushed a massive surge that overtopped levees and floodwalls in the greater New Orleans area, the Army Corps of Engineers has completed raising the area levees, rebuilding flood walls, and creating a massive Lake Borgne Surge Barrier. The Hurricane and Storm Damage Risk Reduction System is designed to provide a 100-year level of protection for, and essentially to withstand, a surge created by a Category 1 to Category 3 hurricane. As a result of these changes, a significant number of properties previously in a storm-surge zone will now be out of the extreme- and high-risk zones.

A lack of coastal irregularities such as substantial barrier islands or hills, and the Gulf of Mexico's flat bottom make southern Louisiana especially susceptible to storm surge. New Orleans sits mostly below sea level on the east bank of the Mississippi River and south of Lake Pontchartrain. A Category 5 hurricane striking the New Orleans area would inundate nearly $39 billion worth of residences and more than 278,000 properties with storm surge. If levees are topped or fail, as they did in the case of Hurricane Katrina, the water would be trapped within these areas, causing additional damage. Even if the hurricane is only a Category 1 storm, it could still inundate more than $26 billion worth of property and affect more than 196,000 homes.

#3: Virginia Beach, Virginia

Virginia Beach sits on the Atlantic Ocean at the mouth of the Chesapeake Bay, which is the largest estuary in the U.S., covering more than 64,000 square miles and spanning across several states. The Hampton Roads Core Based Statistical Area (officially known as the Virginia Beach–Norfolk–Newport News, VA–NC CBSA) is the 36th largest in the U.S., with a total population of 1,671,683, according to the 2010 U.S. Census.

A Category 5 hurricane striking the Virginia Beach area could cause nearly $45 billion worth of residential damage and would affect almost 289,000 properties in the area. Even if the hurricane is only a Category 1 storm, it could still cause area residents total property damage of close to $10 billion, impacting more than 59,000 homes.

#2: Miami-Dade/Palm Beach, Florida

The Miami to Palm Beach area is uniquely situated to be impacted from hurricanes traveling from three different directions. These would include a direct hit from the Atlantic Ocean, an indirect hit from a Gulf hurricane passing over the Florida Peninsula and, in the worst scenario, a coast parallel hurricane moving up the coast, directly impacting the entire metro region.

If a Category 5 hurricane hits the greater Miami area, the cost to property could be nearly $45 billion and would affect almost 247,000 properties in the area. Even if the hurricane is only a Category 1 storm, it could cause area residents total property damage of more than $15.8 billion, impacting nearly 52,000 homes.

#1: Long Island, New York

There is a consensus among the scientific community that a Category 5 storm would not be sustainable off the coast of New York due to the cooler waters of the Atlantic. A Category 4 storm, however rare, is possible and would generate significant damage to the Long Island-area of New York if it made landfall.

The storm surge from a Category 4 hurricane slamming Long Island, which is home to some of New York State's wealthiest residences, could cause property damage of nearly $100 billion to residential properties. More than 250,000 properties could be exposed to the resulting storm surge. Even if the hurricane is only a Category 1 storm, it could cause Long Islanders total property damage of over $32.1B impacting nearly 74,000 residential properties.
