Press Release Number: 102-2015

Continuing its aggressive approach to protecting vital regional infrastructure from future severe storms, the Port Authority Board of Commissioners today approved a comprehensive series of street-level flood barriers across the 16-acre World Trade Center site, primarily around the World Trade Center Transportation Hub.

The Board approved $112.9 million for flood mitigation and resiliency projects designed to prevent the extensive level of flooding that occurred at the site following Superstorm Sandy in October 2012. Approximately 75 percent of the cost of the work, up to $84.7 million, will be reimbursed through a grant from the Federal Transit Administration under its Emergency Relief Program.

"The devastating impact of Superstorm Sandy put all of us on notice that more must be done to protect the World Trade Center Transportation Hub and all of our critical transit facilities from the impact of severe weather events," said Port Authority Chairman John Degnan. "We take this challenge seriously and continue to invest in resiliency projects that we believe will provide an extensive level of protection should another major storm strike this region in the future."

"Superstorm Sandy left billions of dollars of damages to Port Authority facilities in its wake, including at the World Trade Center," said Port Authority Vice Chairman Scott Rechler. "Post Sandy, the Port Authority has worked diligently to enhance mitigation efforts to protect critical infrastructure from future storms. These funds will help bolster the resiliency of the region’s assets."

The flood projects at the World Trade Center site include the creation of a perimeter Bollard Protection System on the western end of the site. The system involves modifications to existing street-level security bollards to support removable flood barriers. It uses the bollards to insert stored temporary floodwall panels that can be deployed prior to an impending weather event.

The Port Authority also will install other street-level waterproofing construction – called Water Intrusion Protection Systems – in facilities throughout the World Trade Center including a variety of special vehicle and pedestrian flood doors, gates, louvers, grates, backflow preventers and similar measures.

As part of a pilot project, a section of the Bollard Protection System included in the mitigation projects approved today is already in place. In April 2014, the Board authorized the design and construction of a prototype around the perimeter of the One World Trade Center at the curb line along Vesey, West and Fulton streets. Portions of the One World Trade Center bollard system prototype was successfully deployed in October 2014, with remaining field deployments around the tower completed in early 2015.

The Board also approved today the award of a construction contract to Skanska USA Civil, Inc., at an estimated total cost of approximately $3.6 million, to fabricate and install the next section of the perimeter Bollard Protection System at the World Trade Center’s Vehicular Security Center and Tour Bus Parking Facility. The system will be located along Liberty, West, Cedar and Greenwich streets.

The projects announced today are part of a comprehensive flood mitigation plan developed for the World Trade Center site. Additional measures are also being considered by the Port Authority.
