Rainfall-Absorbing Green Roofs Installed at the Brooklyn Navy Yard

The Brooklyn Navy Yard just got a little greener as the waterfront industrial complex installed three new eco-friendly rooftops.

The new furnishings have a 23,000-square-foot structure planted with ornamental grasses, perennial wildflowers and sedum, which will absorb rain — replacing previously impervious roofs that would often promote flooding from the nearly 2.5 million gallons of rain in a typical year.

“The city’s Department of Environmental Protection Green Infrastructure Grant Program encourages property owners to do their part in managing stormwater and keeping it out of our sewage system,” said DEP Commissioner Vincent. sapienza. “This project is a great example of a partnership between the government and a strong community leader to build the green infrastructure that has improved the sustainability of the Navy Yard and is already helping to maintain the health of the East River and New York Harbor.” improve.”

The new project also aims to create and conserve biodiversity while supporting local ecology, which is often overlooked in major cities but has significant impacts, according to Borough President Eric Adams, Democratic candidate for mayor.

“Green roofs are a critical tool in reducing the urban heat island effect, promoting biodiversity, and reducing stormwater runoff and flooding. These new installations at the Brooklyn Navy Yard are critical as we assess the effects of a face a rapidly changing climate. I look forward to working with DEP to promote this needed infrastructure in our community,” said Adams.

The 33rd Council District, which includes the Navy Yard along with surrounding waters, is being hit hard by stormwater runoff, and these new green roofs will help the cause.

The green roof at 3 Flushing Ave. and 25 Navy St. on Admirals Row now includes 11,736 square feet of intensively constructed roof and will handle approximately 1,800,000 gallons of rainwater annually.

Kelco Construction was the prime contractor overseen by New York Green Roofs. The DEP grant of $351,788 and the Steiner NYC contribution of $537,000 were paid to the project.

The building at 399 Sands St, near Admiral’s Row in the Brooklyn Navy Yard, will now have a 11,465 square foot sedum green roof. Brooklyn Grange was the prime contractor for that project, with landscape design by Michael Van Valkenburg Architects. The green roof was funded entirely by a $344,881 DEP grant and will manage approximately 660,000 gallons of stormwater annually.

Steiner NYC is one of 33 partners to whom DEP has committed funds under the grant program. In total, DEP allocated more than $13 million to the grant program partners, who in turn contributed nearly $7 million in matching funds. Non-profit organizations, private homeowners and businesses are entitled to green-roof modernization grants for stormwater management on private land. DEP accepts applications continuously throughout the year.

Projects that are profitable, reproducible and generate sufficient funding or other contributions will be considered.

The push to renovate Brooklyn’s buildings comes amid a series of devastating floods, including last month when the remnants of Hurricane Ida flooded large areas of the neighborhood, killing at least a dozen people in New York City.

Adams, who is most likely to become the city’s chief executive next year, has emphasized storm resilience as part of his political platform.

“Let’s face it, we’ve ruined the planet. Folks, climate change is here,” Adams said late last month. “We are faced with a range of problems that affect quality of life. It has an impact on our health, it has an impact on our public safety.”
