A resident bought a house on Butter Lane because of what sat next to it. An open field. Reserve proximity was the whole pitch, and it worked. The resident told the Southampton Town Planning Board the reserve was the reason for buying the house in the first place.
Except that field has spent the better part of a decade in a fight. The owner of the nine-acre reserve beside the resident's house, an investor named Adam Shapiro who bought the parcel in 2015, has pushed for animal shelters, alpacas, and a proposed greenhouse on land covered by an easement that, as the East Hampton Star reported, dates to 1996. The Bridgehampton Civic Association reported that a judge ruled against the owner. The case is on appeal. As recently as April 15, 2026, the Bridgehampton Civic Association reported that Shapiro was forced to withdraw a variance request for animal husbandry after four years and seventeen adjournments.
The Butter Lane dispute offers a recent example of questions about an agricultural easement in Bridgehampton and how they can be addressed.
What the Easement Covers
Southampton Town's agricultural reserves work through recorded easements. That's the legal backbone behind Bridgehampton's most expensive real estate story: a farm field becomes worth more standing empty next to your house than it would be worth to you as buildable land.
The clearest recent proof is the 27-acre parcel the Peconic Land Trust acquired from the Topping family in Bridgehampton, farmed for more than 150 years on some of the most productive soil on Long Island. The deal came together through $18 million in community donations layered with $30 million from Southampton Town's Community Preservation Fund. Town Supervisor Maria Moore framed the goal plainly: keep the land available to working farmers and forever dedicated to food production, not development.
That's what buyers are actually paying for when a listing sits beside a reserve.
How Easement Enforcement Works
The enforcement question has been tested repeatedly. The dispute has run since at least 2019, when Shapiro first sought variances for worker housing. It resurfaced through 2023 and 2024 with a proposed greenhouse and a 2024 letter from the town's Agricultural Advisory Committee objecting to moving the building envelope. A judge sided with the town on the housing question in a ruling that mirrored a similar case, Peconic Land Trust v. First Blue East LLC. Both rulings are on appeal.
None of this happened quietly. Neighbors organized a dedicated site to track the dispute and press for enforcement. The Bridgehampton Civic Association and Group for the East End filed formal opposition. Another neighboring resident told the Planning Board the reserve next door was the reason she bought her house in the first place.
The lesson for a buyer isn't that reserves are risky. A field that looks permanently empty on a listing sheet can still generate hearings, legal fees, and years of uncertainty for the people who live beside it.
Who Pays to Keep the Promise
Southampton Town says the Peconic Bay Community Preservation Fund tax runs 2.5 percent of the purchase price, made up of a 2 percent base rate plus a 0.5 percent housing fund surcharge.
Here's the detail that catches people off guard. The standard exemption, the first $400,000 of an improved residential parcel, only applies when the purchase price is $2 million or under. Above that threshold, there's no carve-out. On a $10 million estate near a Bridgehampton reserve, that means the tax runs on the full purchase price: $250,000, separate from the price of the house itself.
That tax is also the exact mechanism funding deals like the Topping acquisition. But the Bridgehampton Civic Association has noted something worth sitting with: a large volume of new-build and resale activity in the hamlet has sent plenty of money into the fund in recent years, with comparatively few of those dollars coming back out as new open-space purchases in Bridgehampton itself. The fund is healthy. The pipeline of new reserves near existing homes isn't necessarily growing at the same pace.

A Median That Doesn't Hold Still
Buyers comparing Bridgehampton against other Hamptons markets will run into a second wrinkle: the price data itself is unusually noisy right now, and reserve-adjacent estates are part of the reason why.
Over the three months ending June 2026, the trailing median sale price in Bridgehampton sat at $2.0 million, down 24.1 percent from the same period a year earlier, with only one recorded home sale that June. Set that against Corcoran's first-quarter 2026 East End market report, which showed the Bridgehampton/Sagaponack submarket's median and average price both surging 86 percent year over year, driven in part by an oceanfront sale that closed at $58 million, the most expensive reported closing in the region that quarter.
Those two numbers aren't contradicting each other so much as describing a market where transaction counts are thin enough that one estate-scale sale can swing the average in either direction. Miller Samuel's read on the broader Hamptons trend applies directly here: much of the shift isn't price appreciation on comparable homes, it's a change in which homes are selling. A single ultra-high sale near a reserve can make the whole hamlet look like it repriced overnight, when what actually happened is that one buyer paid a premium for one specific guarantee.
The practical takeaway is not to distrust either number. It's to stop leaning on hamlet-wide medians when comparing a reserve-adjacent listing and instead look at what closed on that specific road, in that specific price band, in the last two quarters.
What To Actually Ask Before You Buy Next to a Reserve
- Ask to see the recorded easement language directly, not a summary. The building envelope, permitted structures, and prohibited uses are spelled out there.
- Ask whether any variance or zoning applications are pending on the reserve itself or adjacent parcels. Butter Lane shows how long these can run.
- Ask who has historically enforced the easement's terms: the town, a civic association, or individual neighbors filing complaints.
- Ask whether the CPF has purchased or expanded protected acreage nearby recently, or whether the current footprint of protected land is essentially fixed for now.
- Budget the transfer tax separately from the purchase price, especially above the $2 million exemption threshold.
A Few Questions Worth Settling First
Does an agricultural easement guarantee the field stays farmed forever? It doesn't guarantee the farming looks the way you picture it, or that disputes over what counts as farming won't happen.
Does the CPF transfer tax apply the same way to every purchase? No. The exemption on the first portion of an improved parcel only applies at $2 million or under. Above that, the 2.5 percent tax typically applies to the full purchase price.
If you're weighing a reserve-adjacent property in Bridgehampton against something similar in Water Mill, Sagaponack, or East Hampton, the comps rarely tell the whole story on their own. We can walk the easement language, the recent CPF activity, and the actual closed sales on that specific road with you before you write an offer. Mala Sander+Team knows this market road by road.
