Seawall & Bulkhead Guide: Wildwood, New Jersey
Wildwood is a city in Cape May County, New Jersey, built on Five Mile Beach, a barrier island facing the Atlantic Ocean. Per Wikipedia, the city covers just 1.65 square miles total (1.54 square miles of land, 0.11 square miles of water) and sits at an elevation of only 7 feet above sea level. That combination — a narrow barrier island at single-digit elevation — is exactly the kind of geography where the question of shoreline hardening comes up, and where the ocean-facing side of a barrier island and its back-bay side can call for genuinely different answers. This page lays out the real, general distinction between a seawall and a bulkhead, why Wildwood's barrier-island setting makes that distinction relevant, and is direct about what this research could and could not confirm specific to Wildwood itself.
Seawall or Bulkhead: Two Different Jobs, Not One
A seawall is built to take a direct hit from open-water wave energy — it stands between breaking surf and whatever sits behind it, whether that is a dune, a foundation, or a stretch of open ground. 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 canal, a lagoon, or a sheltered bay margin.
On a barrier island like the one Wildwood sits on, that distinction usually maps cleanly onto geography: the ocean-facing side deals with direct surf, the kind a seawall (or, more often on this coast, a dune and beach-replenishment system) is built to absorb, while the back-bay side, facing the calmer water between the island and the mainland, is the more likely candidate for a bulkhead. The right question for any specific Wildwood lot is not "seawall or bulkhead" as an abstract choice, but which side of the island — and which body of water — that lot actually faces.
A Barrier Island at 7 Feet
Wikipedia records Wildwood’s elevation at just 7 feet above sea level, across a total land area of 1.54 square miles on Five Mile Beach. That is a genuinely low, genuinely narrow footprint, and it means storm surge, wind-driven tides, and heavy rain all have very little vertical distance to travel before reaching streets and structures — on either side of the island. It is also the kind of geography common to barrier-island towns up and down the New Jersey shore, where the back-bay side, facing calmer water toward the mainland, is the side more often associated with bulkheads, while the ocean side faces the Atlantic directly.
None of that is a substitute for a site-specific look at any individual Wildwood property. It is offered here as the documented geographic backdrop — barrier island, 7-foot elevation, ocean on one side and bay on the other — against which a seawall-versus-bulkhead question in Wildwood should start.
What Is Typical on New Jersey Barrier Islands
Bulkheads along the back-bay side are a common feature of New Jersey barrier-island towns generally — a familiar sight where residential lots meet lagoons, canals, or the bay itself, holding soil in place along calmer water. That general pattern is well established across this stretch of the Jersey Shore. What this page does not have is anything specific to Wildwood: no confirmed bulkhead ordinance number, no confirmed permit cost, no confirmed maintenance requirement, and no named, existing bulkhead or seawall tied to a specific Wildwood parcel, its age, or its condition.
Saying "bulkheads are common on New Jersey barrier islands" is a documented, general statement about the region’s geography and typical construction. Saying "Wildwood requires X for a bulkhead permit" or "a Wildwood bulkhead costs $Y to install or repair" would be an invented, specific claim this research did not confirm — and this page draws that line deliberately rather than blur it for the sake of sounding more complete.
A City Built for a Different Kind of Landmark
Wildwood's own defining identity, per the research behind this site, is not primarily about shoreline engineering — it is the Doo Wop Capital of the USA, home to a state-recognized historic district of 1950s and 1960s Googie/populuxe motel architecture and a boardwalk tramcar that has run continuously since 1949. That matters here only in that it underscores how little of Wildwood's public documentation touches on shoreline-hardening specifics: this is a boardwalk-and-motel town by reputation, and no current (2025-2026) storm-damage, erosion event, or beach-replenishment project specific to Wildwood was confirmed in the research behind this page.
That gap is worth naming rather than papering over. A barrier-island city at 7 feet of elevation is exactly the kind of place where shoreline questions matter, and exactly the kind of place where a generic, borrowed answer from another Jersey Shore town would be a mistake to rely on.
What This Page Does Not Confirm
No confirmed, current Wildwood bulkhead ordinance number, permit cost, application timeline, or maintenance requirement was located in the research behind this page, and none is invented here. No named, existing seawall, bulkhead, or shoreline structure tied to a specific Wildwood parcel, its age, condition, or repair or replacement cost was confirmed either. No current (2025-2026) storm-damage, erosion event, or beach-nourishment project specific to Wildwood was confirmed in this research pass.
Also unconfirmed: current Cape May County or City of Wildwood property tax rates, New Jersey's state sales tax rate as it applies to a specific transaction, current median home prices, current active-listing counts, and current FEMA flood-zone designations for any individual parcel. Wildwood is this site's second New Jersey market, following Cape May, and New Jersey's tax structure and coastal-permitting framework are genuinely different from Delaware's — nothing about a Delaware town's rules should be assumed to carry over here.
Who Actually Regulates This in New Jersey
The New Jersey Department of Environmental Protection (NJDEP) is the right first call for current coastal-permitting requirements touching any shoreline-hardening project in Wildwood, whether the frontage in question is the open Atlantic side of Five Mile Beach or the back-bay side facing the mainland. 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. The City of Wildwood's own building and zoning department is the right local source for any bulkhead or seawall permit specific to a given parcel, including whatever current ordinance and fee schedule actually applies there.
For anything specific to an actual lot — whether a back-bay bulkhead needs repair or replacement, what a current permit costs, or what maintenance a given structure requires — 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 Wildwood 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.

Wildwood's location on Five Mile Beach in Cape May County, New Jersey, its 1.65-square-mile total area (1.54 sq mi land, 0.11 sq mi water), and its elevation of 7 feet above sea level are sourced from Wikipedia's own Wildwood, New Jersey entry. This page states, as a general and documented pattern, that bulkheads along the back-bay side are common on New Jersey barrier-island towns generally; it does not claim a specific Wildwood bulkhead ordinance, permit cost, or maintenance requirement, none of which was confirmed in the research behind this page, and none of which is invented here. No named, existing seawall or bulkhead tied to a specific Wildwood parcel, its age, condition, or cost, and no current New Jersey coastal-permitting rule, fee, tax rate, or flood-zone designation, was confirmed either. Confirm current bulkhead and seawall permitting requirements directly with the City of Wildwood'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 Wildwood property. Nothing on this page is legal, insurance, engineering, or financial advice.
