Flood Zones in Long Beach, New York: A City Built on a Barrier Island, Not a Retreat From One

This page is about Long Beach, New York, a city of 35,029 people in Nassau County on Long Island's South Shore — not Long Beach, California, and not one of the Suffolk County Hamptons markets. Long Beach sits entirely on Long Beach Barrier Island, a strip of land less than a mile wide from the Atlantic Ocean to Reynolds Channel and roughly 3.5 miles long, with a total area of just 3.90 square miles split between 2.22 square miles of land and 1.68 square miles of water. That geography, combined with a population density of 15,795.5 people per square mile, means flood exposure here is not a theoretical resort-town concern — it is a fact of daily life for tens of thousands of year-round residents packed onto a narrow strip of sand between an ocean and a channel. Hurricane Sandy proved that in 2012. None of that history, however, adds up to a confirmed FEMA flood zone letter for any specific address, because no such figure was independently confirmed during this research pass. What follows separates the documented geography and storm history from the address-specific determination that only FEMA can provide.

A Barrier Island City, Not a Barrier Island Village

Long Beach was settled in 1623, incorporated as a village in 1913, and became a city in 1922 — a governance history that already sets it apart from every other Long Island beach market built on this site, all of which sit in Suffolk County and remain villages or hamlets. Long Beach sits in Nassau County, entirely on Long Beach Barrier Island, bordered by Reynolds Channel on the bay side and the Atlantic Ocean on the ocean side. The city's total area is 3.90 square miles, of which 2.22 square miles is land and 1.68 square miles is water — meaning nearly a third of the city's official footprint is water, a ratio that reflects just how thin and exposed this strip of land actually is. The island runs less than one mile wide from ocean to bay and approximately 3.5 miles long, so almost no property in Long Beach sits far from either body of water.

The 2020 Census recorded a total population of 35,029, at a density of 15,795.5 people per square mile — reported as the 34th densest city in the United States by the source behind this research. That density is not a footnote. It means Long Beach absorbs storm and flood risk across a much larger year-round population, packed far more tightly, than any of the lower-density Hamptons villages covered elsewhere on this site. Fewer than 40 percent of housing units here are detached houses, and the city functions primarily as a bedroom community for New York City commuters via the Long Island Rail Road, which extended service to Long Beach in 1880. The 2019 American Community Survey put median household income at $97,022, with a racial and ethnic composition of 71.9 percent non-Hispanic white, 16.3 percent Hispanic or Latino, 6.2 percent Black, and 2.7 percent Asian residents.

October 29, 2012: Hurricane Sandy Hits the Boardwalk and the City

Hurricane Sandy struck on October 29, 2012, and it is the single clearest, most fully documented flood event in Long Beach's modern history. The storm caused more than $250 million in damage citywide, destroyed hundreds of vehicles, and destroyed the Long Beach boardwalk outright — a 2.2-mile-long structure that traced back to real estate developer William H. Reynolds' original early-1900s vision of Long Beach as "the Riviera of the East." This is a resolved, decided piece of history, not an ongoing dispute: Sandy hit, the boardwalk came down, and the city rebuilt.

That rebuild was funded with $39 million in FEMA grants and $4.4 million in state reimbursement. The boardwalk reopened in sections by July 2013 and was fully restored by October 2013. The scale of that damage figure and that federal-grant-funded rebuild is, on its own, a stronger and more specific documented flood event than exists for most other Long Island markets — it is real evidence that storm surge here reaches building-destroying levels, even though it does not by itself establish a current FEMA flood zone boundary for any individual lot.

Why This Is Not a Hamptons-Style Flood Story

Every other Long Island beach market already documented on this site — Montauk, East Hampton and Amagansett, Southampton, Bridgehampton, Sagaponack, and Westhampton Beach — sits in Suffolk County and functions as a wealthy resort or second-home destination. Long Beach does not fit that mold, and treating its flood risk as a smaller version of a Hamptons story would misrepresent the market. It is a genuine bedroom-community city where fewer than 40 percent of housing units are detached houses, where a Long Island Rail Road commute defines daily life for many residents, and where the "quiet beach atmosphere" attracts working professionals rather than second-home buyers. Flood exposure in a market like this affects renters, condo and co-op owners, and multi-family building owners at a scale and in a mix that a low-density resort village simply does not have to reckon with.

Long Beach's governance history includes one more piece of decided, resolved history worth knowing before assuming this is a sleepy town: Mayor Louis F. Edwards was assassinated by a police officer in 1939, after which residents adopted the council-manager system the city still uses today, run today by a City Manager. That history, along with the 1931 Starr Faithfull case and Prohibition-era bootlegging scandals documented for the city, is mentioned here only to underline that Long Beach has a real, specific, sometimes dramatic history of its own — not to substitute for flood-zone data, which is a separate question addressed below.

What FEMA Zone Labels Generally Mean, Before Looking Up Any Address

FEMA flood maps typically classify coastal ground using a small set of recurring zone labels, and it helps to understand what those labels mean in general before pulling up any specific Long Beach address. Zone VE denotes the coastal high-hazard area, where wave action of three feet or more is expected during the base flood, usually closest to open ocean frontage. Zone AE denotes the standard base floodplain, sharing the same one-percent annual chance of flooding as Zone VE but without the added wave-action hazard. Zone X generally denotes areas of moderate or minimal flood risk, outside the mapped high-hazard zones.

Given that Long Beach occupies a barrier island less than a mile wide, with water making up nearly 43 percent of its total area, and with the Atlantic Ocean on one side and Reynolds Channel on the other, it would not be surprising if multiple zone designations exist across different blocks of the city depending on ocean-side versus bay-side exposure and ground elevation. That is a reasonable expectation based on the documented geography, not a confirmed fact about any specific parcel. Only a FEMA lookup tied to an exact street address, or a licensed surveyor's elevation certificate, can answer the question for a specific building.

No Confirmed FEMA Flood Zone Designation for Any Address

This page does not state that any part of Long Beach falls into Zone AE, Zone VE, Zone X, or any other specific FEMA 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 Long Beach tends to either market it as an affordable beach town near New York City without engaging its real flood and storm history, or risks getting confused in casual search results with the unrelated city of Long Beach, California — a mix-up this page is written to avoid entirely. To be unambiguous: everything on this page concerns Long Beach, New York, on Long Beach Barrier Island in Nassau County, not the Pacific coast city of the same name.

A $250 million storm-damage figure and a fully documented, FEMA-grant-funded boardwalk rebuild are not the same thing as a current, parcel-specific flood zone determination, and neither should be treated as a substitute for one. Pull the current flood zone, base flood elevation, and any Community Rating System discount directly from FEMA's Flood Map Service Center using the exact street address, and confirm how it applies with the City of Long Beach 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 Long Beach was confirmed during this research pass, and none is estimated here. No specific current retail or restaurant business listings beyond what is already documented for the city were confirmed either. What is documented, and included above because it is real and specific to this market, includes the 1939 assassination of Mayor Louis F. Edwards and the resulting shift to council-manager governance, the 1931 Starr Faithfull case, Prohibition-era bootlegging history, and notable past and current residents such as Vernon and Irene Castle, Billy Crystal, Derek Jeter, Joan Jett, Rick Rubin, MF Doom, Humphrey Bogart, James Cagney, and Rudolph Valentino.

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 City of Long Beach building department, or a licensed insurance agent — rather than filling the gap with a plausible-sounding number borrowed from a denser city or a neighboring Long Island resort market.

What to Actually Check Before Buying Here

Confirmed: Long Beach sits entirely on Long Beach Barrier Island in Nassau County, at 3.90 square miles total (2.22 land, 1.68 water), less than a mile wide from ocean to bay and about 3.5 miles long; Hurricane Sandy struck on October 29, 2012, caused over $250 million in damage, and destroyed the boardwalk, which was rebuilt with $39 million in FEMA grants and $4.4 million in state reimbursement, reopening in sections by July 2013 and fully by October 2013. 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 city.

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, listing agent, or condo/co-op board for any elevation certificate on file, and get a real flood-insurance quote from a licensed agent rather than estimating one from the city's storm history. Separately, confirm any local building requirement with the City of Long Beach 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.
