THE BOERUM HILL BEHEMOTH

INApril, local efforts to stop a proposed $900 million glass building complex at 80 Flatbush — which would dwarf brownstone blocks in Boerum Hill and Fort Greene — went international.

At 4:50 a.m. one morning, a poll on the NIMBY site Block80FlatbushTowers.org was flooded with votes in favor of the project. According to data shared with The Post by the poll’s author, Fort Greene activist Ben Richardson, the early-morning votes came from far-flung nations like South Africa, Holland and Romania.

Could it have been another example of Russian meddling in a vote? “It’s possible,” Richardson said when asked if a troll brigade was behind the hack.

That incident is just one small example of the intensity of feelings surrounding a proposed rezoning that would allow for a 986-foot “supertall” skyscraper (the designation for any building higher than 984 feet) that would tower over the borough’s current tallest building, the 602-foot Hub at 333 Schermerhorn St. The 74story behemoth at 80 Flatbush would be part of a fivebuilding complex that includes a 38-story structure and houses a high school, elementary school and community space, as well as offices and apartments.

While other large buildings like the Hub and the his- toric Williamsburgh Savings Bank Tower already exist on the nearby blocks around Barclays Center, local organizations are fighting tooth and nail to slash the scale of Alloy Development’s project, which sits on a transitional block in brownstone-laden Boerum Hill.

“It’s overly dense and a bad precedent for Brooklyn,” said Howard Kolins, president of the Boerum Hill Association.

His group objects to the height of the project, the placement of the schools and the lack of setbacks on the tower. “We get labeled a NIMBY, but it has never been our position that nothing be built,” he said. “We are for respectful and intelligent development.”

There’s also a splinter group that maintains a community garden at nearby 95 Rockwell Place and is campaigning against the development.

“We have been surrounded by 35- to 50-story buildings and it’s [already] affected our sunlight,” said Ron Janoff, 74, a retired teacher and the coordinator of the 40-yearold Rockwell Place Bears Community Garden, which grows vegetables, grapes and flowers. “Virtually everything we currently grow in the garden couldn’t be grown in the shadow of 80 Flatbush.”

Thanks in part to the opposition efforts, New York City Councilmember Stephen Levin and Brooklyn Borough President Eric Adams have joined the chorus, saying they would like to see the scale of the project reduced. However, the proposed cuts aren’t enough for angry locals.

“Not everyone would agree that dropping 20 stories from 986 feet to 600 feet is a win,” Kolins said.
