World Trade Center Critical Infrastructure Protection


Location: New Jersey and New York Port Authority

Michael Baker International prepared a flood hazard evaluation and developed a comprehensive water intrusion protection plan for the new World Trade Center in Manhattan, NY. Michael Baker International's services included a complete flood and sea level rise risk analysis, development of adaptation strategies and order-of-magnitude cost estimates, stakeholder coordination, and engineering design. Coastal storm surge models were integrated with two-dimensional land surface flow models to identify potential hazards at the project site. An integrated sub-surface flooding model for all of the below-ground floors and passage ways was then developed to assess the potential flooding conditions and develop strategies to mitigate impacts. The water intrusion protection plan is designed to protect all completed World Trade Center facilities from water intrusion under severe exposure conditions. It reduces risk of flooding to allow the complex to maintain operations following a storm surge event, as witnessed during Hurricane Sandy in 2012. When complete, the new World Trade Center will include five new skyscrapers, the National September 11 Memorial and Museum, a multistory transportation hub, 550,000 square feet of retail space, and a 1,000-seat performing arts center. Michael Baker International has supported the Port Authority in taking a rigorous and proactive approach to its flood and climate change adaptation efforts in order to protect these economic assets and national treasures for future generations.
