67,000 CT Homes At Risk from Hurricane Storm Surges; State Ranks 14th Among States Under Threat

More than 6.8 million homes on the Atlantic and Gulf coasts are at potential risk of damage from hurricane storm surge inundation with a total reconstruction cost value of more than $1.5 trillion, according to a new analysis by CoreLogic.  Connecticut, which has felt the brunt of major east coast storms in recent years, ranks 14th among the states in the potential damage from future storms, with more than 67,000 homes at risk of flood exposure. According to the analysis, nearly 7,000 Connecticut homes are at extreme risk from future storms, another 21,600 homes are at very high risk, and nearly 18,000 are at high risk, depending upon the severity of the storm.  In addition, just over 21,000 homes are seen as being of moderate risk.  In the analysis, a category 1-5 storm would place a structure at extreme risk, a category 2-5 storm at very high risk, a category 3-5 storm at high risk, and a category 4-5 storm would put a home at moderate risk.

In addition to the number of homes at risk, the analysis also provides the reconstruction cost value (RCV), which is the cost to completely rebuild a property in case of damage, including labor and materials by geographic location, assuming a worst-case scenario at 100-percent destruction.  The analysis points out that the location of hurricanes that hit land is often a more important factor than the number of storms that may occur during the year.hurricane-irene-damage-ct-nat-guard-east-haven

At the state level, Texas and Florida, which have the longest coastal areas, consistently have more homes at risk than other states. Florida ranks first with 2.7 million at-risk homes across the five risk categories and Texas ranks third with 531,169 at-risk homes.  Since the number of homes at risk strongly correlates with the accompanying RCV, these two states rank first and fifth, respectively for having the largest RCV, according to the analysis.

The states with the most at-risk homes are Florida, Louisiana, Texas, New Jersey, New York, Virginia, South Carolina, North Carolina, Massachusetts, Georgia, Maryland, Mississippi, Pennsylvania, Connecticut and Delaware.

Rhode Island, Maine and New Hampshire ranked 17th, 18th and 19th respectively.

The CoreLogic storm surge analysis, officials say, complements Federal Emergency Management Agency (FEMA) flood zone information to provide a snapshot of potential damage exposure at the property level since many properties located outside designated FEMA flood zones are still at risk for storm surge damage.  The analysis examines risk from hurricane-driven storm surge for homes along the Atlantic and Gulf coastlines across 19 states and the District of Columbia, as well as for 88 metro areas.states

“Using more granular-level data has given us an even clearer picture of which homes are at risk of storm surge damage,” said Dr. Tom Jeffery, senior hazard risk scientist for CoreLogic. “Despite the overall increases in risk, we were glad to see that the number and value of homes in the most extreme, and dangerous, category actually declined.”

At the regional level, the Atlantic Coast has just under 3.9 million homes at risk of storm surge with an RCV of $953 billion, and the Gulf Coast has just over 2.9 million homes at risk with $592 billion in potential exposure to total destruction damage.roadwater

When the states are ranked by the anticipated reconstruction cost value of the homes at risk, Connecticut ranks 12th.

Among the nation’s major metropolitan areas, those with the most homes potentially affected by all categories of hurricane are Miami, New York Tampa, New Orleans, Virginia beach, Cape Coral, Houston, Bradenton, Naples, Jacksonville, Philadelphia, Charleston, Boston, Myrtle Beach and Lafayette.

The official hurricane season extends from June-November each year, but hurricanes are not limited to that timeframe.  The report indicates that most preseason forecasts to date have predicted an increase in both the total number of storms and the number of hurricanes in 2016, compared with the last three years. The storm predictions from Tropical Storm Risk, for example, show a 35 percent chance of this year being an above average season.
