Damage to older structures worse following Hurricane Sandy

A review by AIR Worldwide reveals that parts of Atlantic City, New Jersey witnessed flood depths of six to eight feet at the hands of Hurricane Sandy.

Two AIR teams surveying damage in New York and New Jersey found significant damage to commercial and residential structures located along the coast.

“Older buildings generally experienced higher wind damage than did newer buildings — typically to roof coverings, siding, and flashing, in comparison to newer buildings,” Cagdas Kafali, principal engineer, research for AIR Worldwide, notes in the statement.

The catastrophe modelling firm reports Sandy’s diameter made it the largest Atlantic hurricane on record in terms of the span of tropical storm-force winds. That huge radius helped to keep the winds at Category 1 intensity and allowed the storm to interact with a system from the west that resulted in severe weather across a wide swath of the eastern United States.

The team’s observations in surveyed areas include the following:

  • the ground floor and basements of virtually all retail stores and large commercial structures on Atlantic City’s iconic boardwalk were flooded, with mould observed in a few small retail stores;
  • some buildings near the coast in Ocean City, New Jersey remain uninhabitable because of more than two feet of water still inside;
  • homes in Long Beach Island, New Jersey suffered significant storm surge damage to both their structure and contents; and
  • a record storm tide of 11.28 was recorded at the Battery North American Vertical Datum gauge in Lower Manhattan, producing significant flooding.
