Seawall & Bulkhead Guide: Margate City, New Jersey
Margate City is a city in Atlantic County, New Jersey, on Absecon Island, a barrier island it shares with Atlantic City, Ventnor City, and Longport. Wikipedia puts Margate's total area at 1.63 square miles, 1.42 of it land and 0.22 water -- a narrow strip of ground running from the Atlantic Ocean on one side to the back bay on the other. That narrow, ocean-to-bay footprint is not an abstraction: on the night of August 22, 2025, Hurricane Erin's storm surge triggered more than 50 water rescues in Margate, including roughly 30 people pulled from flooded restaurants on low-lying Amherst Avenue, according to 6ABC Philadelphia's coverage. A city built this way, with private property exposed to open ocean on one edge and calmer bay or back-channel water on the other, is a place where bulkheads and seawalls are a genuinely practical, everyday concern for property owners -- not a niche one. This page lays out the general distinction between the two structures, what Margate's own geography and the real 2025 flooding event tell a property owner and what they do not, and where to go for New Jersey's real coastal-construction permitting requirements -- without inventing a permit fee, a contractor name, or an engineering spec for any Margate property.
Seawall or Bulkhead: Two Different Jobs, Not One
A seawall is built to absorb direct, open-water wave energy -- it stands between breaking surf and whatever sits behind it. A bulkhead is a narrower, calmer-water answer to a different problem: typically a vertical wall of timber, vinyl, steel sheet piling, or concrete, built to hold back soil and stabilize an edge along water that is not throwing breaking waves at it, such as a back-bay channel, lagoon, or sheltered margin.
On a barrier island as narrow as the one Margate shares with Atlantic City, Ventnor City, and Longport, that distinction maps directly onto geography. The Atlantic-facing side deals with direct surf and beachfront exposure, while the bay-facing side deals with calmer water and a different set of maintenance questions. A property owner on the ocean side and a property owner on the bay side of the same small city are not necessarily solving the same structural problem, even though both may describe what they have as a seawall or a bulkhead.
What Hurricane Erin Actually Showed in August 2025
On the night of Thursday, August 22, 2025, Hurricane Erin's storm surge caused flooding that triggered more than 50 water rescues in Margate -- 6ABC Philadelphia reported at least 30 people rescued from Amherst Avenue restaurants, including Sofia's and Maynard's, both of which flooded, plus 16 people and 3 dogs rescued from stranded vehicles using high-water rescue vehicles. Maynard's owner Steve Troiano described the scene directly: "We had wet vacs. We were pumping it out of the back door and it was coming in the front door." Margate Fire Chief Daniel Adams warned residents afterward to heed lifeguard warnings and stay alert to rip currents in the days following the storm. A gas leak, an underground transformer fire, and an electrical fire were also reported that night, and officials anticipated similar flooding risk at the following high tides.
That is a real, dated, named flooding event on a specific, low-lying Margate street -- not a hypothetical. It does not, by itself, tell a property owner whether any particular bulkhead or seawall along Amherst Avenue or elsewhere in Margate held up, needed repair, or played any role at all in that night's water rescues; the confirmed reporting covers the rescues, the flooded businesses, and the utility incidents, not the condition of any specific shoreline structure. What it does show is that low-lying, water-adjacent property in Margate is exposed to real storm-surge flooding, which is exactly the kind of exposure that bulkhead and seawall maintenance is meant to address on the structural side, separate from drainage and flood-proofing on the building side.
CAFRA and Coastal Construction Permitting in New Jersey
New Jersey regulates coastal construction, including bulkhead and seawall work, under real state law -- most notably the Coastal Area Facility Review Act (CAFRA), administered by the New Jersey Department of Environmental Protection (NJDEP). Work on or near the water in a shore city like Margate -- whether repairing an existing bulkhead, replacing a seawall, or building a new one -- is the kind of project that typically falls under this state permitting framework, in addition to whatever local building and zoning approval the City of Margate requires.
This page does not know, and does not state, a specific CAFRA application fee, a required setback, a specific engineering standard, or how long a review takes for a given Margate lot. None of those figures were confirmed in the research behind this page, and none is invented here. A property owner considering bulkhead or seawall work should treat CAFRA and local permitting as a real, mandatory step to confirm directly, not a formality to assume away.
What This Page Does Not Confirm
This page does not state, and does not know, any Margate bulkhead or seawall ordinance number, the current cost of a bulkhead or CAFRA permit application, or any specific maintenance requirement tied to owning or repairing a bulkhead here. No such figures were confirmed in the research behind this page, and none is invented. No contractor name and no specific engineering spec for any Margate bulkhead or seawall is asserted anywhere on this page.
No current (2026) permanent population figure beyond the 2020 census count of 5,317, no current median home price, no current active-listing count, and no current Atlantic County or City of Margate property tax rate is stated here. No current New Jersey state sales tax rate is stated here either -- New Jersey has its own real sales tax and a property-tax structure genuinely different from Delaware's no-sales-tax framing. No current FEMA flood-zone designation for any individual Margate parcel is stated on this page, and whether the August 2025 Hurricane Erin flooding caused any structural or permanent damage beyond the confirmed water rescues, gas leak, and fires is not confirmed here either.
What a Property Owner Should Actually Ask
Given Margate's narrow, ocean-to-bay footprint and the real August 2025 flooding on Amherst Avenue, a straightforward, practical question for any oceanfront or bayfront property here is whether an existing bulkhead or seawall is present, and if so, its age, material, and condition -- timber, vinyl, steel sheet piling, and concrete all age differently, and a structure built decades ago may not meet a current permit standard even if it was compliant when built. A second question worth asking is how a given property fared during the August 2025 storm surge, and whether any repair or reinforcement work has been done since -- a question best answered by the current owner, a title search, or a direct inspection, not by anything general on this page.
Neither question can be answered in general terms on a page like this one. Both are property-by-property questions for the City of Margate's own building and zoning department, the New Jersey Department of Environmental Protection, and a licensed inspector or coastal engineer who can look at the actual lot.
Who Actually Regulates This in New Jersey
The New Jersey Department of Environmental Protection (NJDEP), including its administration of the Coastal Area Facility Review Act (CAFRA), is the right first call for current coastal-permitting requirements for any bulkhead or seawall work in Margate. The City of Margate's own building and zoning department is the right local source for a permit application specific to a given parcel, current fees, and current inspection requirements. The U.S. Army Corps of Engineers is the relevant federal authority for dredging, navigation, and federally authorized shore-protection work in the same waters.
For anything specific to an actual lot -- whether an existing bulkhead or seawall needs repair or replacement, whether it meets current standards, or what a current permit costs -- the sound next step is a licensed New Jersey marine contractor or coastal engineer who can inspect the site directly, plus direct confirmation from the City of Margate and NJDEP on current rules. Confirm flood-zone status separately through FEMA's Flood Map Service Center. Nothing on this page is legal, engineering, or permitting advice.

The August 22, 2025 Hurricane Erin flooding -- more than 50 water rescues in Margate, roughly 30 people from flooded Amherst Avenue restaurants Sofia's and Maynard's, 16 people plus 3 dogs from stranded vehicles, Maynard's owner Steve Troiano's quote, Fire Chief Daniel Adams's rip-current warning, and the reported gas leak, transformer fire, and electrical fire -- is sourced from 6ABC Philadelphia's own coverage of the event. This page does not state any Margate bulkhead or seawall ordinance number, current permit cost, or maintenance requirement, none of which was confirmed in this research pass; no contractor name or specific engineering spec is stated or implied here. No current population beyond the 2020 census count of 5,317, median home price, active-listing count, property tax rate, New Jersey sales tax rate, or FEMA flood-zone designation specific to Margate was confirmed via primary-source research this pass, and whether the August 2025 flooding caused structural or permanent damage beyond the confirmed rescues, gas leak, and fires is likewise not confirmed. Confirm current bulkhead and seawall permitting requirements directly with the City of Margate's building and zoning department and the New Jersey Department of Environmental Protection (NJDEP), consult the U.S. Army Corps of Engineers on federally authorized shore-protection or dredging work, check current flood-zone status through FEMA's Flood Map Service Center, and have any site-specific structural question answered by a licensed New Jersey marine contractor or coastal engineer before planning work on a Margate property.
