In March 2014, the Center for an Urban Future documented an array of challenges and vulnerabilities resulting from the New York City's aging infrastructure in their "Caution Ahead" report (see ED555648). And it identified a minimum investment of $47.3 billion over the next five years to bring the city's core infrastructure to a state of good repair. The current study provides a five-year update to the Center's assessment of New York City's aging infrastructure vulnerabilities. It concludes that Mayor Bill de Blasio administration's record infrastructure investments have resulted in real progress in several areas, but also finds that capital needs across many city agencies have grown significantly--and not just in high-profile areas like the subways and New York City Housing Authority (NYCHA). The Center's new analysis shows that some of the problems that were documented five years ago have only gotten worse, and that the new stressors like climate change have only added to the overall price tag to bring the city's core infrastructure to a state of good repair.
