Town Line Road
Town Line Road's center line is the boundary between Wainscott in East Hampton Town and the Village of Sagaponack in Southampton Town, from Montauk Highway to the beach.
Town Line Road is a boundary drawn down the middle of a road. In the words of The East Hampton Star, the double-yellow stripes running its length "make up the official dividing line between the hamlet of Wainscott and the Village of Sagaponack, in East Hampton and Southampton Towns respectively."
That makes it the one lane on this list where two towns, and an incorporated village, govern opposite sides of the same street. A house on the east side is in Wainscott and answers to the Town of East Hampton. A house across the road is in Sagaponack, an incorporated village in the Town of Southampton, with its own zoning, building department and village board. Taxing jurisdictions and beach permit systems follow the same split.
Two rulebooks on one road
The practical consequences are larger than they look. Zoning districts, allowable floor area and the permit process are set by different codes on each side. A comparable sale across the road may have been built under a different code. A buyer should start with the parcel's tax map district, not its mailing address; addresses on the road carry a mix of Sagaponack, Wainscott, East Hampton and Sag Harbor names.
The two governments also share the road's problems. After a 2022 fatal accident involving a construction vehicle south of Montauk Highway, East Hampton considered stop signs where Town Line Road meets Wainscott Main Street, Daniel's Lane, Hedges Lane and Parsonage Lane. Sagaponack proposed a sidewalk on its side, a turnaround at the beach end for emergency vehicles, and the removal of landscaping and anti-parking devices encroaching on village-owned strips along the road. A buyer on the Sagaponack side should confirm where the private lot ends and the village strip begins.
The beach end
The road ends at the ocean. At the time of the 2022 reporting, holders of East Hampton Town beach passes could park along the Sagaponack side of the road almost to Wainscott Main Street, and Sagaponack had asked East Hampton to consider restricting that parking. Current beach operation, parking and any drive-on rules at this road end should be confirmed with both municipalities before anything is said to a buyer.
New York State administers the Coastal Erosion Hazard Area along the ocean on both sides. The Town of East Hampton's coastal program records that groins on the East Hampton Village beach have affected beaches to the west, which includes this stretch.
Questions to settle before contract
- Which side of the center line is the parcel on, and which village or town issues its permits?
- Does the survey show any encroachment onto a village-owned or town-owned strip along the road?
- Which zoning code applies, and what floor area and coverage remain under it?
- Are the comparable sales drawn from the same municipality?
- What beach parking or access does the owner actually hold?
- For oceanfront parcels: dune position, the erosion hazard line and lawful structures.

Flood and coastal exposure
9 of 115 residential and vacant parcels sit in FEMA’s 1% annual-chance flood area (zones VE, AE, A or AO), where a mortgage from a federally regulated or insured lender requires flood insurance on the building.
| FEMA zone | Parcels | What it means for an owner |
|---|---|---|
| VE — coastal high-hazard (wave action) | 2 | Ocean-facing land exposed to storm waves of 3 feet or more. Flood insurance is required with a federally backed mortgage and costs the most here. A new or substantially rebuilt house must stand on piles or columns, with its lowest structural beam at or above the base flood elevation, and only breakaway walls below. |
| AE — 1% annual-chance flood, base flood elevation set | 7 | A 1% chance of flooding in any year (about 26% over a 30-year mortgage). Flood insurance is required with a federally backed mortgage. A new or substantially improved house must have its lowest floor at or above the base flood elevation shown on the map; local codes can require more. |
| X (shaded) — 0.2% annual-chance flood | 2 | A 0.2% annual chance of flooding (the “500-year” flood). Flood insurance is not federally required, but it is usually available at lower rates and a lender may still ask for it. |
| X — minimal flood hazard | 104 | Outside the mapped flood areas. Flood insurance is not federally required. Flooding can still happen from heavy rain and drainage. |
Loans. In zones VE, AE, A and AO, any mortgage made, insured or bought by a federally regulated lender, Fannie Mae, Freddie Mac, FHA or VA requires flood insurance on the building for the life of the loan. A lender can require it in zone X as well. A cash buyer is not required to insure.
Premiums. Since 2021 the National Flood Insurance Program prices each house on its own features (elevation, distance to water, cost to rebuild), so the zone is a starting point, not the price. Private flood policies are an alternative. An elevation certificate is the document every insurer asks for.
Renovating. In the 1% flood area, if work on a house costs half or more of the building’s market value, or a storm damages it that badly, the whole house must be brought up to current flood rules, which usually means raising it. Plan a renovation budget against that line.
