How Brooklyn's Green-Wood Cemetery plans to stop watery graves...due to flooding

 About 600,000 bodies are buried in Green-Wood Cemetery. During Hurricane Sandy, more than 100 stones were knocked over. Some graves flooded. Photo taken Oct. 19, 2022.

Climate change isn’t just affecting the living. During Hurricane Sandy, the dead were flooded in their tombs in low-lying graveyards across the city.

On the rolling verdant hills of Brooklyn’s Green-Wood Cemetery, the storm brought down about 300 trees and destroyed well over 100 tombstones. The roads and paths on the property were inundated in up to 4 feet of water, making it hard to get in or out.
This month, the nearly 500-acre graveyard announced a plan to protect its roughly 600,000 final resting places against future floods — while also keeping its tranquil gardens open to the public. This resiliency project will invest more than $2 million to store water in dedicated places well under the grounds, which would alleviate the burden on the city's sewers — the main source of the flooding problem.

“Water pools anywhere it needs to – even graves for that matter,” said Frank Morelli, facilities manager at Green-Wood Cemetery. “But we do whatever we have to do because tomorrow someone needs to be buried and nothing's going to stop that.”

To mitigate flooding on the landmark funerary grounds’ paved surfaces, rain gardens along roads and paths will capture additional stormwater that would otherwise make roads inaccessible or send a deluge into the ponds. The project aims to alleviate up to 2 inches of stormwater from the sewer system and store it for irrigation. It is the first design under the Resilient NYC Partners program, a $53 million municipal initiative launched in June 2021 to help private property owners green their land and manage onsite stormwater.

“If you want to solve this challenge, which is basically managing the rain where it falls, you have to come up with partnerships like this one,” said Craig Holland, senior director of investments for the Nature Conservancy’s Healthy Cities Program. The Nature Conservancy is an adviser on the project. “Cemeteries are one of the largest land uses in suburban and urban properties in the United States,” he added.

The program’s strategy will focus on reducing sewer overflow, and that means moving beyond funding climate resiliency for just public property. In partnering with private property owners, the city government hopes to spread flood protection all over the five boroughs.
