(New York, NY - WNYC) A Port Authority of New York and New Jersey official says a built-out World Trade Center site will be less vulnerable to future storms like Sandy once construction is done by 2020. But the authority hasn't decided what to do in the meantime to protect the site from rising tides.
Construction sites that include open pits, as does the 16-acre World Trade Center site, are vulnerable to flooding. And much of the site is built on landfill where the Hudson River once flowed--and would flow again if not for retaining walls.
But Port Authority executive director Pat Foye wouldn't elaborate on what steps could be taken to protect the site from flooding while under construction, and harden the site once construction is done in an age of climate change and rising sea levels.
"Port Authority people and outside experts are looking at how to make the site more resilient," Foye said. He wouldn't give details about possible mitigation efforts beyond saying, "The review continues."
Foye estimated it will cost $2 billion to repair storm damage to the World Trade Center, along with the rest of the authority's facilities, including airports, bridges and tunnels. Foye said $800 million alone is needed to fix the PATH train system, which only recently returned some of its lines to a pre-Sandy schedule.
Foye said insurance reimbursements and FEMA payments should cover those costs."There will be no material impact on the budget," he said.
Still under construction in Lower Manhattan is One World Trade Center, which carries a price tag of $3.8 billion, making it the world's most expensive new office tower. To offset the costs of the 1,776-foot skyscraper, the authority last year levied higher bridge and tunnel tolls and reduced spending on transportation infrastructure.
One World Trade Center is scheduled to be done by early next year. But some part of the larger World Trade Center site will be under construction, and vulnerable to flooding, for at least the next eight years.
