Flood Zones in Westhampton Beach: A Barrier-Beach Village That Has Already Moved Houses to Escape the Water

A Barrier-Beach Village, Incorporated in 1928

Westhampton Beach incorporated as a village in 1928, within the Town of Southampton, Suffolk County, on Long Island's South Shore. The village runs its own police, ambulance, and fire departments, and is served by the Westhampton Beach Union Free School District. The Long Island Rail Road reaches the area via its Montauk Branch, and the village is served by Sunrise Highway (NY 27) and Montauk Highway (CR 80). The village's total area is just 3.0 square miles — 2.9 square miles of land and only 0.1 square miles of water — a small, narrow footprint that comes directly from sitting on a barrier beach rather than a broad mainland shoreline.

The 2020 Census recorded a population of 2,150, up from 1,902 in the 2000 Census. The 2000 Census also recorded a demographic makeup of 89.17 percent White, 4.63 percent African American, 1.16 percent Asian, and 7.68 percent Hispanic or Latino residents, with a median household income of $58,438, a median family income of $74,412, and roughly 9 percent of the population living below the poverty line — all dated figures from 2000, not current 2026 numbers, and included here only to establish the historical record, not to describe today's market.

The Storm That Defined the Village: September 21, 1938

The single most defining event in Westhampton Beach's history is the "Long Island Express," the hurricane that struck on September 21, 1938. It devastated the community, destroyed nearly all of the summer homes standing on the barrier beach, and caused twenty-nine deaths in Westhampton Beach specifically. This is a fully resolved historical disaster — it is not an ongoing dispute or an active hazard in the way a current storm would be — but it is the clearest evidence available that this barrier-beach location has, within living memory of the community's own records, taken a direct and catastrophic hit from a hurricane.

Chronic Erosion and the Mid-1990s Relocation of Fifteen Houses

Beach erosion became a critical, chronic problem in Westhampton Beach beginning in the 1960s, and it did not stay abstract. In November 1992, a nor'easter destroyed more than eighty homes here and prompted renewed intervention from the U.S. Army Corps of Engineers. The clearest illustration of how seriously the eroding shoreline was taken came in the mid-1990s, when fifteen historic houses were physically relocated inland specifically to save them from the encroaching water — not a hypothetical risk assessment, but houses actually picked up and moved because the ground under them was disappearing. Hurricane Sandy, in 2012, required additional restoration work along the shoreline on top of that history.

No specific dollar figure for the November 1992 nor'easter damage or for the cost of the mid-1990s house-relocation project was confirmed during this research pass, and none is estimated here. What is documented is the sequence itself: a chronic erosion problem serious enough to destroy over eighty homes in a single storm and to require moving fifteen historic structures away from the shoreline entirely, followed by further Sandy-related restoration two decades later.

What Flood Zone Labels Like VE and AE Actually Mean, Generically

FEMA flood maps generally sort coastal high-risk ground into a handful of recurring categories, and it is worth understanding these labels in the abstract before ever pulling up a specific Westhampton Beach address. Zone VE is the coastal high-hazard designation, applied where storm-surge wave action of three feet or more is expected, typically closest to open ocean and inlets. Zone AE is the standard base-floodplain designation, covering ground with the same one-percent annual chance of flooding but without that same wave-action hazard. Zone X generally marks areas of minimal or moderate flood risk that sit outside the mapped high-hazard zones.

Given that Westhampton Beach sits on a barrier beach only 3.0 square miles in total size, with 2.9 square miles of that being land, it would not be surprising if multiple zone designations exist within the village depending on how close a given lot sits to the ocean side versus the bay side, and how the ground elevation compares. But that is a reasonable expectation, not a confirmed fact about any specific parcel — only a FEMA lookup tied to an exact address, or a licensed surveyor's elevation certificate, can answer the question for a specific lot.

No Confirmed FEMA Flood Zone Designation for Any Address Here

This page does not state that any part of Westhampton Beach falls into a specific FEMA flood zone, whether Zone AE, Zone VE, Zone X, or any other designation, and it does not state a base flood elevation or Community Rating System classification for any address, because no such figure was independently confirmed during this research pass. Existing coverage of Westhampton Beach tends to treat it as a smaller, more affordable Hamptons alternative for real-estate shoppers, without engaging seriously with the 1938 hurricane or the beach-erosion and house-relocation history documented above — that gap is exactly what this page is trying to close honestly rather than paper over with a guessed-at flood zone.

A documented history of catastrophic storm damage and shoreline erosion is not the same thing as a current flood zone determination, and it should not be treated as a substitute for one. Pull the current, parcel-specific flood zone, base flood elevation, and any Community Rating System discount directly from FEMA's Flood Map Service Center using the exact address, and confirm how it applies with the Westhampton Beach Village building department before budgeting for flood insurance or planning any renovation.

What the Research Did Not Find, and Will Not Invent

No exact current (2026) home price, property-tax rate, or flood-insurance premium specific to Westhampton Beach was confirmed during this research pass. No specific dollar figure for the November 1992 nor'easter damage or the mid-1990s house-relocation project cost was confirmed. No specific named local businesses, restaurants, or current Main Street retail listings were confirmed either. Three properties here are listed on the National Register of Historic Places — the Crowther House, the Foster-Meeker House, and the U.S. Post Office — and that fact is included because it is documented, not as a stand-in for flood-zone data, which is a separate question entirely.

Where the research turns up a documented gap rather than a hard figure, the honest move is to say so plainly and point toward the real source — FEMA, the Westhampton Beach Village building department, or a licensed insurance agent — rather than filling the gap with a plausible-sounding number borrowed from a neighboring Long Island market.

What to Actually Check Before Buying Here

Confirmed: Westhampton Beach incorporated as a village in 1928; it endured a catastrophic hurricane on September 21, 1938, with twenty-nine deaths; chronic erosion beginning in the 1960s led to a November 1992 nor'easter that destroyed over eighty homes; and fifteen historic houses were relocated inland in the mid-1990s to escape the eroding shoreline. Not confirmed, and not invented on this page: any specific current FEMA flood zone letter, base flood elevation, Community Rating System discount, or 2026 flood-insurance premium for any address in the village.

Before making an offer here, pull the current flood zone and base flood elevation from FEMA's Flood Map Service Center using the exact address, ask the seller or listing agent for any elevation certificate on file, and get a real flood-insurance quote from a licensed agent rather than estimating one from the village's storm history. Separately, confirm any local building requirement with the Westhampton Beach Village building department, and have a real-estate attorney or other licensed professional review flood-related conditions before closing. Nothing on this page is legal, tax, insurance, or financial advice.
