Walk the malls between 54th and 86th Streets this week and you will see the summer begonias on their way out and the first flats of fall chrysanthemums going in. It looks like routine city maintenance. It is not. Every bulb, every mum, every sculpture pedestal on that stretch is paid for by the buildings that line it, not by the city of New York.

Between 46th and 57th Streets, a different project is underway on Park Avenue. Mayor Zohran Mamdani and the Department of Transportation just unveiled an updated redesign of the avenue there, backed by tens of millions of dollars in capital funding and direct contributions from JPMorganChase and Vornado. The two projects on the avenue follow fundamentally different funding models, though many people walking either one may assume it is all the same budget. It is worth knowing how each is funded.

Vandalism on the Park Avenue Malls

As UESRPT reported, someone destroyed the tulip plantings at both ends of the mall between East 76th and 77th Streets in April. The vandalism was reported to police. The bulbs themselves survived underground, so the flowers were expected to return, and the nonprofit that plants them said it had never dealt with this kind of vandalism before.

The plantings on this stretch of Park Avenue are maintained through donations, an arrangement that has continued for decades.

Forty-Six Years of the Same Handshake

The gardens on the malls have a long history of public and private involvement. In the 1950s, urban beautification advocate Mary Lasker started planting begonias and tulips on some of the malls to prove to the city that greenery could survive the traffic and pollution of a Manhattan avenue. She eventually convinced the Parks Department to take over maintenance, and in 1970 the department hired landscape architect Clara Coffey to redesign the malls, stripping out old fencing and hedges and building the planting beds still visible today.

By 1980 the city had stopped paying for the upkeep and the malls were falling apart. Ronald D. Spencer, then president of Carnegie Hill Neighbors, worked out an arrangement where the buildings north of 86th Street would each contribute based on the number of apartments they held. Lasker liked the model enough to push for it below 86th Street too, and that same year the privately funded Park Avenue Malls Planting Project launched under Margaret Ternes. It has run continuously since, now operating as The Fund for Park Avenue, covering the malls from 54th to 86th Streets and relying entirely on the buildings and residents along that stretch to keep it alive.

That history explains why April's vandalism registered the way it did. It was not an act against city property. It was an act against a collective the neighbors themselves built and still fund every year.

What's Actually on the Median This Week

If you have walked past the malls near 66th and 67th Streets recently, you have seen "Talisman," a sculpture by Michele Oka Doner installed there earlier this year as part of a rotating public art program run jointly by the Fund and NYC Parks' Art in the Parks initiative. It is scheduled to come down in October, which means the next few weeks are the last chance to see it in place.

Further along the corridor, Manolo Paz's ten-piece installation, "The Distance That Unites," has been on view since late April and was scheduled to close this September. If you have not walked past it yet, the window is closing now, not later this fall.

Underneath both installations, the seasonal handoff is happening on its usual clock. The Fund oversees three plantings a year on this stretch: spring tulips, summer begonias, and fall chrysanthemums, plus the ongoing care of the trees and shrubs that make the malls readable as a garden rather than a traffic island. The mums arriving now are the same rotation that has run since the Planting Project's earliest years, just with a different color palette each season.

A Different Kind of Money on Park Avenue

None of that donor-funded rhythm applies to the redesign underway between 46th and 57th Streets. That project sits directly above the Grand Central Terminal train shed, which Metro-North is rehabilitating in phases, and the city is using the disruption as a chance to rebuild the avenue above it at the same time.

The funding structure looks nothing like the malls conservancy to the north:

• Sector 1, tied to JPMorganChase's new headquarters at 270 Park Avenue, came in $20 million under budget and is on track for substantial completion by the end of 2026.
• Sector 2, running from East 46th to East 50th Street, is being managed by JPMorganChase with a $50 million contribution.
• Sector 3, from East 50th to East 53rd Street, is being managed by Vornado with a $25 million contribution tied to the redevelopment of 350 Park Avenue.
• The broader design work moved forward this summer when the East Midtown Public Realm Improvement Fund Governing Group approved a $39 million outlay following a July 14 meeting.

That governing group exists because of the 2017 Greater East Midtown Rezoning, which requires new commercial development and transfers of development rights to fund public realm improvements nearby. In plain terms, the redesign between 46th and 57th Streets is paid for by the same zoning mechanics that let towers like 270 Park Avenue get built taller. The malls to the north are paid for by whoever writes a check to a nonprofit each spring.

The design itself will widen the medians, add seating and a two-way protected bike lane, and create new crosswalks connecting the malls along the eleven-block stretch. As Mayor Mamdani put it when the update was announced, the goal is putting "more space where it belongs: in the hands of New Yorkers."

Two Corridors, Two Calendars

If you live above 54th Street, the plantings outside your window are a community project older than most of the buildings' current residents, sustained one donation at a time since 1980. If you live or work near the 40s and 50s, the disruption you are seeing is capital construction tied to zoning bonuses and corporate real estate deals, moving on an entirely different funding clock. Neither version of Park Avenue is more official than the other. They are just funded by different rooms.

The next marker on the malls' own calendar is the annual tree lighting, a tradition the Fund has run since 1945 as a memorial to New Yorkers lost in the Second World War. It will happen the same way it always has: because enough people on this avenue decided, again, to pay for it themselves.

If you're weighing a move to this corridor, or already call it home and have questions about what a building's participation in the Fund says about how it's run, Daniella Schlisser has spent years inside Park Avenue's co-ops and can walk you through what these small civic details actually mean for a building and a block.
