Mamdani Targets McDonald and Coney Island Avenues for Brooklyn Housing Overhaul Ahead of IBX

New York City’s latest rezoning push in southern Brooklyn could signal a new era of transit-linked housing strategies—and test the city’s mettle in tackling its housing crunch.

In New York, the surest marker of urban reinvention is the steady hum of construction cranes. It is thus telling that, according to City Hall, the corridor south of Brooklyn’s Prospect Park could soon sprout as many as several thousand new homes—assuming Mayor Zohran Mamdani’s administration can shepherd its freshly unveiled “South of Prospect Plan” from blueprint to reality. Eyed for sweeping change are the low-slung storefronts, auto shops, and modest homes that for generations have lined McDonald and Coney Island avenues—blocks that, for now, largely escape the developer’s gaze.

Plainly put, the plan is ambitious. Announced on May 20th, City Planning’s initiative will rezone commercial stretches and adjacent blocks for taller buildings and greater housing density, guided by the tenets of “transit-oriented development.” Unlike many past rezoning bids, this one looks resolutely to the future: it banks on a coming light rail, the Interborough Express (or IBX), which will slice across the neighborhoods, bringing swift links not just to Manhattan but—crucially—to Queens.

The logic behind the proposal is solid, if familiar. With four subway lines and, soon, the IBX, the area south of Prospect Park is what urbanists call “transit-rich.” As Planning Director Sideya Sherman told local press, the neighbourhood enjoys enviable connectivity—making it a prime candidate for denser housing. The city is betting that proximity to trains and trams will tempt both newcomers and existing residents to swap a car for a MetroCard, to the benefit of the local economy and the environment alike.

The implications are substantial for New York City’s ailing housing supply. Rents have crested record highs, and some 70,000 people leave the five boroughs yearly for cheaper climes—figures that bode poorly for the city’s long-term vibrancy. Mamdani’s administration says its goal is to add 200,000 new units of affordable housing over the coming years, and neighbourhood-focused rezonings are now the sharp end of that policy spear. The South of Prospect Plan is both a test case and an early salvo in a wider campaign.

It also portends bruising politics. Unlike some notorious rezonings of the past decade, which confronted entrenched opposition, this proposal has, for now, earned unusually buoyant support from local Councilmembers Shahana Hanif and Rita Joseph. “I support it because it’s about planning ahead,” Ms Joseph told reporters—a stance not always typical for members wary of backlash from current residents. The administration nonetheless promises months of community engagement before it drafts detailed rules next year. Anxieties about displacement, loss of local character and affordability pervade every corner of neighborhood politics in Brooklyn; sceptical voices can be counted on to surface as particulars emerge.

For developers and housing advocates alike, the brewing focus on “transit-oriented” strategies marks a notable inflection. Public policy in New York has long privileged incrementalism over bold redesign: arcane zoning, environmental reviews under CEQR, NIMBY activism, and the city’s own tortuous approval processes have all conspired to keep new supply puny in the face of crushing demand. Now, both the city and Albany are moving to trim these obstacles. Thanks in part to last year’s voter-approved changes—and new legislation championed by Governor Kathy Hochul, which streamlines environmental reviews—builders may (finally) have a somewhat less Sisyphean job.

From an economic vantage, the stakes verge on existential. Sky-high housing costs, coupled with rising property taxes and stagnant wage growth, have stunted the city’s ability to attract and keep talent. Retail corridors and small businesses, particularly those near mass transit, reek of missed opportunity when hobbled by outdated land-use rules. Fresh housing within walking distance of the IBX could bring a surge of foot traffic and, with it, new spending caches for the local shops that still undergird neighbourhood economies.

Should the plan take shape, it could reconfigure not just neighborhoods but political alignments across the boroughs. Already, the housing debate is fomenting new alliances—between transit boosters, younger progressives, and business interests—while older coalitions fray under the pressures of affordability and change. This is not just Brooklyn’s problem; cities from San Francisco to Toronto and London have dabbled, with fitful results, in tying housing growth to transit expansion. Their records are decidedly mixed. Sizeable new inventories of flats have not always materialised, or have quickly been overwhelmed by pent-up demand. But well-designed infill near stations has, at its best, revived moribund districts—and sometimes, made the difference between demographic stagnation and renewal.

The transit-housing tangle

What of the perils? Undeniably, “transit-oriented development” is more slogan than panacea. If history holds, new housing in popular, well-connected enclaves will quickly fetch a premium—hardly a surprise in a city where even modest flats now command king’s ransoms. To counter this tendency, the Mamdani administration will have to wield zoning carrots and sticks with unusual dexterity: mandating meaningful shares of new units for below-market tenants, preventing speculators from gobbling up lots, and ensuring that planning does not outpace investment in public schools, parks and basic infrastructure.

The global record suggests caution. In London’s Docklands, or along Paris’s RER lines, density encouraged by new transport links has sometimes sparked speculation and “luxuryification” at the expense of affordability. Yet such lessons, if heeded, could inform New York’s next moves. A robust survey and genuine resident input—already underway—aim to divine which mix of height limits, commercial space, and tenant protections might yield growth without alienation.

Still, the best antidote to New York’s perennial housing woes remains the obvious one: more homes, everywhere, and preferably near trains. If Brooklyn can show that thorough public process, legal reform, and political consensus can finally deliver new apartments where they are most needed, it would mark a quiet but profound achievement.

Only time will confirm whether the “South of Prospect Plan” becomes merely another well-meaning gesture—or the blueprint for a city unafraid to build. But at last, residents and builders alike are invited to imagine a Brooklyn less defined by what is forbidden than by what might be possible. ■
