Urban Conservation Easements: Pocket Parks and Community Gardens in Perpetuity

Part of our conservation easement series. Start with the complete guide or the step-by-step how to start your own conservation easement.

On the evening of May 12, 1999, New York City’s community gardeners went to bed expecting to lose everything. The next morning, 114 lots they had spent two decades coaxing from rubble into tomatoes, roses, and shade, were scheduled for public auction, no use restrictions attached. The deal came at the last possible hour: the Trust for Public Land purchased 63 of the gardens for $3 million, and the New York Restoration Project, the nonprofit Bette Midler founded, took the remaining 51 for $1.2 million, pulling every lot off the auction block and preserving them in perpetuity. Local land trusts in Brooklyn, Queens, Manhattan, and the Bronx were later chartered to own them forever. A quarter century on, those gardens are still growing, and the episode remains the clearest demonstration in American history of a simple fact: in a city, green space that is not permanently protected is green space waiting for a closing date.

Which raises the question landowners, garden groups, and community foundations keep asking: can you put a conservation easement on an urban lot, a pocket park, a community garden, and make it permanent? The answer is yes, with an honest asterisk about how urban protection usually works in practice.

Is an urban conservation easement legally viable?

Yes. A conservation easement on an urban lot is legally viable and federally deductible when it serves a qualifying purpose under Internal Revenue Code Section 170(h)(4), and two of the four purposes fit city land naturally: preservation of land for outdoor recreation or education for the general public, and preservation of open space pursuant to a clearly delineated governmental conservation policy, which many municipal open space and urban greening plans provide. Here urban easements hold an odd advantage over their rural cousins: the recreation purpose requires public access, which most rural landowners decline, and public access is precisely what a pocket park or community garden exists to offer. A garden gate that opens to the neighborhood is not a concession in the deed. It is the qualifying purpose itself.

The urban math: small lots, enormous easement values

Easement value is the gap between developed and restricted value, and nowhere is the gap more violent than on a buildable city parcel. A quarter-acre lot zoned for six stories may be worth millions as development rights and a small fraction of that as a permanent garden, meaning the donor of an urban easement is giving away nearly the whole value of the land. That produces a proportionally large deduction, and proportionally large IRS attention: urban easements, especially the historic facade variety, have their own enforcement history, and an urban easement appraisal must be bulletproof. It also produces a quieter, more practical benefit. A private owner holding a lot as a garden pays carrying costs on development-value assessments; an easement that legally extinguishes the development rights gives the assessor grounds to tax the land as what it now permanently is. For the family that owns the corner lot the neighborhood gardens, that alone can be the difference between holding on and selling out.

How urban green space actually gets protected: three structures

Easement on private land. The classic form. An owner keeps the lot, donates an easement to a land trust restricting it to garden, park, or open space use forever, takes the deduction, and the protection binds every future owner. Right for the owner who wants to keep the land in the family and the garden in the city.

Land trust ownership. The dominant form, and the New York model. A land trust acquires the lot outright, as TPL and NYRP did in 1999 and as Chicago’s NeighborSpace, a public land trust created in 1996, has done across that city, and holds it for community use. Most community gardens sit on land the gardeners never owned, so there is no owner-donor to grant an easement; acquisition is the tool that fits.

The belt-and-suspenders layer. The sophisticated form: the garden land trust owns the lot, and a second conservation organization holds an easement over it. Now permanence does not depend on any single board’s future judgment, because no one can sell what another organization holds the right to prevent. For community groups asking how to make sure a garden survives their own institution, this two-organization structure is the strongest answer American law offers.

Making a community garden permanent: the realistic playbook

If your group gardens on private land, the conversation is with the owner about a donated or bargain-sale easement, or about selling the lot to a land trust. If you garden on municipal land under a license, as most groups do, the goal is transfer to parkland status or to a garden land trust, the path the New York gardens ultimately took. Either way, the partner is a land trust with urban practice, and the moment to act is before the lot is worth arguing over. Our directory includes urban greening organizations, garden trusts, and community land groups across the country’s bioregions.

Frequently asked questions

Can you put a conservation easement on a city lot?

Yes. An urban easement is legally viable and deductible when it serves a qualifying purpose under Section 170(h)(4), most often public outdoor recreation or open space under a governmental conservation policy.

Can a conservation easement protect a community garden in perpetuity?

Yes, where the land is privately owned and the owner grants one. Gardens on city-owned land are more commonly protected by transfer to a land trust or to parkland status, and the strongest structures combine land trust ownership with an easement held by a second organization.

Does an urban easement require public access?

Only if it relies on the recreation or education purpose, which requires meaningful public access. Community gardens and pocket parks usually satisfy this by their nature; an urban easement resting on the open space purpose can remain private.

Is the tax deduction for an urban easement large?

Often very large relative to lot size, because the easement extinguishes development rights that dominate urban land value. Large urban deductions draw close IRS scrutiny, so a rigorous qualified appraisal is essential.

Who holds urban conservation easements?

Urban land trusts, garden trusts like those chartered from the 1999 New York preservation deal, citywide open space trusts, and some municipalities. Choose a holder with urban stewardship experience, since monitoring a garden differs from monitoring a ranch.

What happened to the New York community gardens after 1999?

The 114 auction-slated gardens were purchased for $4.2 million by the Trust for Public Land and the New York Restoration Project and preserved in perpetuity, with local land trusts in Brooklyn, Queens, Manhattan, and the Bronx later created to own and steward them permanently.
