New York City Faces Increasing Flood Risk as Metro Area Sinks
New York City’s metropolitan area is sinking, posing a growing threat of flooding for the iconic city. A recent study conducted by NASA’s Jet Propulsion Laboratory and Rutgers University revealed that the region is sinking at an average rate of 0.06 inches per year.
Land modifications, including land reclamation and landfill construction, have loosened and compressed the ground, contributing to the sinking. Arthur Ashe Stadium, constructed on a landfill, is sinking at the fastest rate of 0.18 inches per year. Woodside in Queens, on the other hand, is rising at a rate of 0.27 inches per year.
The sinking issue extends beyond New York City itself. LaGuardia Airport, a crucial transportation hub, is experiencing a sinking rate of about 0.15 inches per year. To tackle this problem and address potential flooding issues, an extensive $8 billion renovation project is currently underway.
The recent study also mentioned Newark, Kearny, and Harrison in New Jersey as areas experiencing sinking, although specific rates were not provided. The study did, however, highlight the significance of the sinking issue in the wider metro area.
The rising sea levels exacerbate the situation. The sea level at The Battery in Manhattan is increasing at a rate of 0.12 inches per year, further raising the risk of flooding for the metropolitan area.
However, it’s not all bad news. The study also revealed that certain parts of Queens and Brooklyn, such as East Williamsburg and Woodside, are experiencing rising land levels. This offers a glimmer of hope amid the concerning sinking trend.
The scale of the sinking problem is vast. New York City is home to over 1 million buildings, collectively weighing nearly 1.7 trillion pounds. These structures sink between 0.03 to 0.08 inches per year, highlighting the widespread nature of the issue. As the city continues to expand with high-rise constructions along coastal, river, and lakefront areas, the risk of future flooding necessitates the development of comprehensive mitigation strategies.
NASA’s sea level prediction tool offers insights into the future. According to scientists, the tool predicts a sea level rise of 0.04 inches by 2100. This estimation underscores the urgent need for proactive measures to address the sinking issue and prevent catastrophic flooding.
As New York City grapples with the reality of sinking land and rising sea levels, stakeholders must collaborate to find sustainable solutions that protect the bustling metropolis and its millions of residents. The issue demands immediate attention and action to ensure the long-term viability of the beloved Heartland city.
