A $108 million project to restore Dumbo’s historic cobblestone streets and upgrade flood infrastructure has received one of the city’s top preservation honors.

The Dumbo and Vinegar Hill street restoration project won the 2026 Lucy G. Moses Preservation Project Award from the New York Landmarks Conservancy.

Engineer Kevin Lin said the project restored 26 blocks of historic cobblestones throughout Dumbo and Vinegar Hill.

“With the modernization of cars, we put the asphalt roadway down, so in order to bring back what Dumbo was at one point, we decided to remove all the asphalt and place all the cobblestones back in the original spots,” Lin said.

Crews removed, cleaned and returned more than 800,000 original stones to their streets.

Lin said the work also included upgrades below ground, including larger sewers, to help prevent flooding in the neighborhood.

“We also increased the sizing of sewers to prevent flooding in the neighborhood. There’s a lot of high-rise buildings and it needs more capacity to sustain development,” Lin said.

Crews also uncovered about 2,800 artifacts during construction, including items dating back to the late 1700s.

Archaeologist Mark Tweedie said one of the discoveries was a colonial smoking pipe.

“We actually found, among all of the rubble, is this beautiful colonial smoking pipe. So this actually has an American Liberty eagle symbol on that dates to about 1820 to 1860,” Tweedie said. Lin said being part of the project was meaningful.

“It feels great to be a part of history,” Lin said.
