Seawall & Bulkhead Guide: Wildwood Crest, New Jersey
Wildwood Crest is a borough in Cape May County, New Jersey, on Five Mile Beach, a barrier island immediately south of Wildwood. Per Wikipedia, the borough covers just 1.48 square miles total (1.30 square miles of land, 0.19 square miles of water) and sits at an elevation of only 3 feet above sea level. On the bay side, Wildwood Crest is bordered by Sunset Lake, which was historically connected to the Atlantic Ocean via Turtle Gut Inlet until that inlet was closed in 1922. That combination — a narrow barrier island at single-digit elevation, with an enclosed former inlet on its bay side — 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 Crest's barrier-island setting and Sunset Lake shoreline make that distinction relevant, and is direct about what this research could and could not confirm specific to Wildwood Crest 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 lake, a lagoon, or a sheltered bay margin.
On a barrier island like the one Wildwood Crest 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 bay-facing side — along Sunset Lake and the calmer water between the island and the mainland — is the more likely candidate for a bulkhead. The right question for any specific Wildwood Crest 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 3 Feet, With Sunset Lake on the Bay Side
Wikipedia records Wildwood Crest's elevation at just 3 feet above sea level, across a total land area of 1.30 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. On the bay side sits Sunset Lake, a body of water that was historically open to the Atlantic through Turtle Gut Inlet until that inlet was closed in 1922; today the surrounding area includes Sunset Lake and Turtle Gut Park. A shoreline that was once a tidal inlet and is now an enclosed lake is exactly the kind of setting where a bay-side property owner might reasonably ask about a bulkhead.
None of that is a substitute for a site-specific look at any individual Wildwood Crest property. It is offered here as the documented geographic backdrop — barrier island, 3-foot elevation, ocean on one side and Sunset Lake on the other — against which a seawall-versus-bulkhead question in Wildwood Crest 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, lakes, or the bay itself, holding soil in place along calmer water, and Sunset Lake's shoreline in Wildwood Crest is the kind of setting where that general pattern would apply. That said, this page does not have anything specific to Wildwood Crest: 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 Crest parcel, its age, or its condition.
Saying "bulkheads along Sunset Lake are a common feature of this kind of New Jersey barrier-island geography" is a documented, general statement about the region's geography and typical construction. Saying "Wildwood Crest requires X for a bulkhead permit" or "a Wildwood Crest 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 Quieter Town With Its Own Real History — Not Primarily a Shoreline-Engineering Story
Wildwood Crest's own defining identity, per the research behind this site, centers on being genuinely quieter than neighboring Wildwood — Wikipedia describes it as "generally set apart from the all-hours excitement" of the broader Wildwoods resort area — and on a real, dated Revolutionary War naval engagement, the June 29, 1776 Battle of Turtle Gut Inlet, fought near what is now Wildwood Crest and honored on the borough's own municipal seal. That matters here only in that it underscores how little of Wildwood Crest's public documentation touches on current shoreline-hardening specifics: no current (2025-2026) storm-damage, erosion event, or beach-replenishment project specific to Wildwood Crest was confirmed in the research behind this page.
That gap is worth naming rather than papering over. A barrier-island borough at 3 feet of elevation, with a bay-side lake that was itself once a tidal inlet, 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 Crest 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 Crest 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 Crest was confirmed in this research pass.
Also unconfirmed: current Cape May County or Borough of Wildwood Crest 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, current (2026) population figures beyond the 2020 census count of 3,101, and current FEMA flood-zone designations for any individual parcel. Wildwood Crest is this site's third New Jersey market, following Cape May and Wildwood, 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 Crest, whether the frontage in question is the open Atlantic side of Five Mile Beach or the bay side facing Sunset Lake. 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 Borough of Wildwood Crest'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 bay-side 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 Borough of Wildwood Crest 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 Crest's location on Five Mile Beach in Cape May County, New Jersey, its 1.48-square-mile total area (1.30 sq mi land, 0.19 sq mi water), its elevation of 3 feet above sea level, and Sunset Lake's history as a bay-side body of water once connected to the Atlantic Ocean via Turtle Gut Inlet until that inlet was closed in 1922, are sourced from Wikipedia's own Wildwood Crest, New Jersey entry. This page states, as a general and documented pattern, that bulkheads along Sunset Lake and other bay-side shorelines are common on New Jersey barrier-island towns generally; it does not claim a specific Wildwood Crest 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 Crest 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 Borough of Wildwood Crest'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 Crest property.
