Seawalls and Bulkheads on the Long Beach Barrier Island
Long Beach, New York sits in Nassau County, on Long Island's South Shore, and it is worth saying plainly at the top: this is a genuine city, not a village or a hamlet, settled in 1623, incorporated as a village in 1913, and chartered as a city in 1922, and it is not to be confused with the much larger Long Beach, California, on the other coast of the country. It occupies a barrier island less than one mile wide from ocean to bay and roughly three and a half miles long, bordered by Reynolds Channel on one side and the open Atlantic on the other, a geography that puts shoreline hardening on the table for almost any waterfront lot here the same way it would on any barrier island. Real estate developer William H. Reynolds founded the modern resort city in 1906 and 1907 with an explicit vision of building "the Riviera of the East," and the boardwalk he built is still the city's defining piece of shoreline infrastructure today. No confirmed, named seawall, bulkhead, or revetment project tied to a specific private property in Long Beach turned up in the research behind this page, and none is invented here. What is confirmed, and what this page focuses on instead, is the fully resolved story of Hurricane Sandy's damage to the public boardwalk, this city's real density and commuter-market identity, and the general New York regulatory framework that governs shoreline hardening statewide.
A Barrier-Island City, Not a Hamptons Village
Every other Long Island market covered on this site so far, including Montauk, East Hampton and Amagansett, Southampton, Bridgehampton, Sagaponack, and Westhampton Beach, sits in Suffolk County. Long Beach sits in Nassau County, and it carries a different legal and civic identity than any of those places: it was settled in 1623, incorporated as a village in 1913, and became a city in 1922, governed today under a council-manager system with five elected council members and a city manager handling day-to-day administration. That city-level governance, on a barrier island packed with high-density housing, is a different starting point for a shoreline-hardening conversation than a low-density resort village.
William H. Reynolds, the developer behind the modern city's 1906-1907 founding, envisioned Long Beach as "the Riviera of the East" and built it out with Mediterranean-style architecture and the original boardwalk. That resort vision explains the boardwalk's prominence in this city's history, but it is a story about public recreational infrastructure, not a record of any private seawall or bulkhead built on any individual lot.
Less Than a Mile Wide: The Geography Behind the Question
Long Beach occupies a barrier island bordered by Reynolds Channel and the Atlantic Ocean, with a total area of 3.90 square miles, 2.22 of it land and 1.68 water. The island is less than one mile wide from ocean to bay and roughly three and a half miles long, which means most of the city sits within a short walk of tidal water on one side or the other. That narrow footprint is the physical reason shoreline hardening comes up as a question at all here, whether the question is about a bulkhead facing Reynolds Channel on the bay side or a seawall or revetment facing the open Atlantic.
The city's own boardwalk, 2.2 miles long, runs along the ocean side and is the most visible piece of shoreline infrastructure in Long Beach. It was originally built as part of Reynolds' resort vision, fell into disrepair through the 1960s and 1970s, and was the subject of urban-renewal investment starting in the 1980s, long before Hurricane Sandy became the more recent chapter in its story.
Hurricane Sandy, 2012: A Resolved Disaster and a Rebuilt Boardwalk
Hurricane Sandy struck on October 29, 2012, and caused more than $250 million in damage to Long Beach, destroying hundreds of vehicles and destroying the boardwalk itself. This is settled, resolved history, not an open or ongoing dispute: the storm happened, the damage figure and the boardwalk's destruction are both confirmed, and none of it should be read as describing a current, unresolved condition.
The boardwalk 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. That is a real, confirmed public-infrastructure rebuild, funded and completed within about a year of the storm, and it stands as the clearest documented shoreline-resilience project in this market's recent history.
What Sandy's Rebuild Does and Doesn't Tell You About Bulkheads Today
It would be easy to read the boardwalk rebuild as evidence about private seawalls and bulkheads elsewhere in Long Beach, and that would be a mistake. The confirmed research behind this page covers a public boardwalk, funded by FEMA and the state, rebuilt as a single city project after a named storm. It says nothing about whether any specific private bulkhead, seawall, or revetment exists on any individual waterfront lot along Reynolds Channel or the ocean block, whether such a structure is currently permitted, or what it would cost to build, repair, or replace one today.
No specific dollar figure for any private hardening project, no permit application, and no permit outcome tied to an individual Long Beach property was confirmed in the research behind this page, and none of that is invented here. A buyer should treat the Sandy boardwalk story as proof that this barrier island has real storm exposure and a track record of public rebuilding, not as a substitute for checking the condition and permit status of the shoreline structure on any specific lot under consideration.
The General Rule: New York State DEC and Often the Army Corps of Engineers
Setting the Sandy boardwalk story aside, the general regulatory framework that applies to shoreline hardening anywhere on the New York coast applies here too: structures such as seawalls, bulkheads, and revetments built along tidal wetlands or the open shoreline typically require a permit from the New York State Department of Environmental Conservation, and work below the mean high water line or affecting navigable water frequently also requires a separate federal permit from the U.S. Army Corps of Engineers. On a barrier island bordered by both a tidal channel and the open Atlantic, a given property could plausibly need to satisfy either agency's review, or both, depending on exactly where the structure sits.
Long Beach's own city government, being a chartered city with a council-manager structure rather than a village board, layers its own local building and waterfront review on top of both state and federal requirements. Anyone considering building, replacing, or repairing a hardening structure here should treat the DEC and the Army Corps as the two outside agencies to contact directly, and the city's building department as the local authority to confirm alongside them, rather than assuming any permit already exists.
A Denser, Commuter City Changes the Buyer Calculus
Long Beach recorded a 2020 census population of 35,029 across its 3.90 square miles, 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 figure. Fewer than 40% of housing units in Long Beach are detached houses, and the city functions largely as a bedroom community for New York City commuters, connected by the Long Island Rail Road. The 2019 American Community Survey put median household income at $97,022. None of that is Hamptons-style resort wealth, and this page does not pretend otherwise; it is a genuinely different buyer profile, oriented toward commuters seeking oceanfront or near-oceanfront living at a comparatively accessible price point rather than second-home buyers in a low-density resort village.
That density matters for the seawall-and-bulkhead question in a practical way: with fewer detached houses and more shared or multi-unit buildings along the shoreline, responsibility for an existing hardening structure, or for building a new one, may sit with a condominium association, a co-op board, or a homeowners' group rather than a single owner. Anyone buying into a shared building near the water in Long Beach should ask specifically who is responsible for any bulkhead or seawall serving the building, and whether that responsibility, and its cost, is addressed in the building's governing documents.
What to Actually Verify Before Buying Near This Shoreline
Confirmed: Long Beach was settled in 1623, incorporated as a village in 1913, and became a city in 1922, in Nassau County, on a barrier island less than one mile wide and about three and a half miles long, bordered by Reynolds Channel and the Atlantic Ocean; Hurricane Sandy struck on October 29, 2012, caused more than $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 fully by October 2013. Not confirmed, and not invented on this page: any specific current seawall, bulkhead, or revetment project, permit application, permit outcome, or construction cost tied to a particular private property here, and no 2026 home-price, property-tax, or flood-insurance figure specific to this market.
Before making an offer near this shoreline, ask the seller, listing agent, or building association directly whether any hardening structure exists on or serving the property and whether it is currently permitted, and independently contact the New York State Department of Environmental Conservation and, where federal jurisdiction may apply, the U.S. Army Corps of Engineers to check permit status. Confirm local building and waterfront requirements with the City of Long Beach building department, and have a New York-licensed coastal engineer and a real-estate attorney review the specific shoreline condition before closing.

Long Beach was settled in 1623, incorporated as a village in 1913, and became a city in 1922; real estate developer William H. Reynolds founded the modern city in 1906-1907, envisioning it as "the Riviera of the East" with Mediterranean-style architecture and the original boardwalk, and Long Island Rail Road service reached Long Beach in 1880, drawing 300,000 visitors in its first season. The city occupies a barrier island bordered by Reynolds Channel and the Atlantic Ocean, with a total area of 3.90 square miles, 2.22 of it land and 1.68 water, less than one mile wide from ocean to bay and roughly three and a half miles long; its boardwalk runs 2.2 miles. The 2020 census recorded a population of 35,029 at a density of 15,795.5 per square mile, reported as the 34th densest city in the United States by the source behind this figure; the 2019 American Community Survey put median household income at $97,022; and the population is 71.9% non-Hispanic white, 16.3% Hispanic or Latino, 6.2% Black, and 2.7% Asian. Long Beach is governed today by a council-manager system with five elected council members and a city manager, adopted after Mayor Louis F. Edwards was assassinated by a police officer in 1939, a fully resolved historical event. Hurricane Sandy struck on October 29, 2012, causing more than $250 million in damage, destroying hundreds of vehicles and 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. No exact current (2026) home-price, property-tax-rate, or flood-insurance figure specific to Long Beach was confirmed, and none is invented here; no specific dollar figure, permit application, or permit outcome for any private seawall, bulkhead, or revetment project tied to an individual property here was confirmed, and none is invented here. This page also does not restate Montauk's separate lighthouse and Camp Hero history, East Hampton and Amagansett's separate 1648, 1680, and 1942 history, Southampton, Bridgehampton, and Sagaponack's separate 1640-founding and three-governance-structure material, or Westhampton Beach's separate 1938 hurricane and 1990s house-relocation history, as if any of it applied here, and it does not conflate this Long Beach, New York with the unrelated city of Long Beach, California. What is stated instead is the general New York regulatory framework: shoreline hardening structures typically require a permit from the New York State Department of Environmental Conservation and often a federal permit from the U.S. Army Corps of Engineers, plus local review from the City of Long Beach building department. Confirm any specific structure's permit status directly with the New York State DEC and the U.S. Army Corps of Engineers, confirm local requirements with the City of Long Beach building department, and consult a New York-licensed coastal engineer and a real-estate attorney before making any purchase or construction decision.
