Insured building values in the US now exceed $80 trillion - and $15 trillion of the exposures are in counties along the Atlantic and Gulf coasts exposed to hurricane and other coastal hazards, according to an analysis put out yesterday by Boston-based Karen Clark & Company.The report finds that the states with the highest hurricane and coastal hazard exposures were New York at $4.94 trillion, Florida at $3.31 trillion and Texas at $1.45 trillion.The analysis is prepared using the company’s RiskInsight risk management platform and includes contents and time element exposures.“Along with increasing values, there are more concentrated pockets of exposures particularly in areas vulnerable to natural catastrophes,” said the company’s report titled, “Increasing Concentrations of Property Values in the US”.The top ten states account for more than 50 percent of the US total property value and the Gulf and Atlantic coastal counties most exposed to hurricanes account for more than 17 percent of property value. The state with the most property value is California, followed by New York and Texas.As the report also notes, despite the economic downturn, the cost to replace residential and commercial properties destroyed by natural disasters has continued to rise. Such costs differ widely by geographic region and occupancy type.
