In May of 2026, Mayor Mamdani and the Deputy Mayor Bozorg published Block by Block.
Like the other pages on the BKCB6 Use of Land hub, this tries to offer a clear-eyed synthesis and the tools to look at this from some new vantage points that may help you better understand it. Housing costs are at a crisis level, and having the best plan possible is important for today, tomorrow, and well into the future for New Yorkers, whether they are here or want to be here.
From the CB6 perspective, we have 2 sites listed in the district, Gowanus Green and the Brooklyn Marine Terminal, which will add thousands of housing units. But this is a crisis that needs everything possible to be done, and it's our number one district need priority, so we'll look to add to this plan. The most immediate example that comes to mind is using 250 Baltic Street (the floors above the CB6 office), as it wouldn't even require a zoning change, is close to transit, and has much of the infrastructure to convert it to housing. Anyway, I'll stop there and ask that you check it out and let me know what you think.

Over the ten years to 2024 the city finished about 26,600 homes a year for a city of more than eight million people. The rental vacancy rate is near zero, well below the roughly 5 percent a functioning rental market needs, and below that threshold landlords hold the leverage, rents rise, and tenants have nowhere to go.
That works out to about one new home for every forty people living here over a decade, and most of it came out of the Gowanus rezoning, without which the figure would be far lower. What comes next sits on the two sites the city has named here, Gowanus Green and the Brooklyn Marine Terminal, neither of which has been built.
