New York City is dangerously exposed to the next superstorm, according to a report from city Comptroller Scott Stringer.

He says it is not a question of whether another storm like Superstorm Sandy will hit, but when.

According to Stringer, the city has not fully recovered from Sandy in the six years since the storm. His report shows the city has only spent 54 percent of nearly $15 billion in federal Sandy funding.

Stringer says he understands it takes time to bring projects to fruition and is calling on the federal government to cut the red tape and streamline the flow of disaster aid dollars.

According to a breakdown of the stats, Stringer says $101 billion in property value is located in the most flood-vulnerable areas of our city. It includes homes, hospitals, businesses and schools in all boroughs.

He is calling on the mayor and stakeholders to create a new citywide resiliency plan.

“We can't piecemeal this. We can't just do Lower Manhattan and not think about the entire coastline,” says Stringer. “People suffered in all of our boroughs. We need to explore creative ideas that would guarantee more dedicated funding streams for resiliency projects."

The mayor's office told News 12 they were looking into the report.
