Continuing its aggressive approach to protecting vital regional infrastructure from future severe storms, the Port Authority Board of Commissioners today approved new mitigation measures to prevent future potential flooding on the World Trade Center site.

The Board authorized an $8.4 million project to install an at-grade Water Intrusion Protection System between West and Greenwich streets, part of an overall $112.9 million Board commitment for flood mitigation and resiliency projects at the World Trade Center site.

The contract authorized today includes the installation of flood barriers, roll down doors, louvers, hatches, structural hardening and waterproofing at or immediately inside building doorways and roadway areas to prevent water from penetrating below-grade areas through elevator shafts, ventilation shafts, stairwells and ramps.

The work continues the Board’s comprehensive investments to provide flood mitigation and storm resiliency at its transportation facilities and at the World Trade Center site following Superstorm Sandy in October 2012. During the storm, approximately 125 million gallons of water flowed onto the World Trade Center site and the below-grade areas, which were still under construction. The flooding resulted in hundreds of millions of dollars in damage to the site.

Including today’s action, the Board has awarded more than $33 million in construction contracts for flood mitigation at the World Trade Center, including completion of a Bollard Protection System and Water Intrusion Protection system at grade level. The bollard protection system includes flood barriers attached to bollards the surround the site’s buildings to provide the first level of protection from potential flood waters. The Water Intrusion Protection Systems in this contract and a previous $13.5 million contract award in June 2017 comprise the second level of protection at building entries and other surface level openings.

A Federal Transit Administration grant will provide for reimbursement of 75 percent of eligible project and contract expenses.

“The devastating impacts from Superstorm Sandy on the region and on our transportation facilities served as a wakeup call that we needed to take immediate steps to better protect all of our assets, including the World Trade Center site,” said Port Authority Chairman Kevin O’Toole said. “We have aggressively taken on this challenge and continue to invest in resiliency projects that will provide an extensive level of protection from future storms.”

“For nearly five years, we’ve worked diligently to bolster the resiliency of all of our assets and to install world-class systems to protect critical infrastructure from future storms,” said Port Authority Vice Chairman Jeffrey Lynford. “But none of us knows when the next storm will hit and we must incorporate new ideas and innovative projects into our comprehensive flood mitigation plan to continue to bolster the resiliency of our assets.”
