Flood Zones in Wildwood, New Jersey: What a Barrier Island at 7 Feet Actually Means
Wildwood is a city in Cape May County, New Jersey, built on Five Mile Beach, a barrier island facing the Atlantic Ocean. Per Wikipedia's own entry for the city, the total area is just 1.65 square miles, 1.54 of them land and 0.11 water, the highest point sits at only 7 feet above sea level, and Wildwood carries the highest population density of any of Cape May County's 16 municipalities. That is a small, low, densely built barrier-island footprint, the kind of geography FEMA's flood maps are specifically designed to scrutinize block by block. This page does not state a current FEMA flood zone designation for any specific Wildwood parcel, and it does not state a current flood-insurance premium for this city, because neither has been confirmed at the citywide level and both are set address by address. What it does do is lay out what is actually documented about the geography driving Wildwood's flood exposure, explain in plain terms how FEMA's flood-zone system works, and point toward where a specific address can be checked. None of this is legal, insurance, or engineering advice — for a question tied to a specific property, talk to a licensed New Jersey insurance agent, a real estate attorney, and the relevant local and federal agencies named below.
A Barrier Island City, 1.65 Square Miles, 7 Feet at Its Highest Point
Wildwood is not set back from the ocean on higher inland ground; it sits directly on Five Mile Beach, a barrier island, per Wikipedia's own entry for the city. At 1.65 total square miles, with land making up 1.54 of that and water accounting for the remaining 0.11, Wildwood is a compact footprint of ocean-facing beach, dense boardwalk-adjacent development, and back-bay marsh and channel frontage on the other side of the island. Its highest point sits at just 7 feet above sea level, meaning there is very little elevation reserve anywhere in the city, and the 2020 census figures place Wildwood's population density first among all 16 municipalities in Cape May County — a small island packed tightly with structures.
That combination, a low barrier-island footprint with almost no natural elevation and a dense built environment, is a geographic fact, not a flood-zone determination for any specific address. Barrier islands like Five Mile Beach generally face exposure from two directions at once: storm surge and wave action from the ocean side, and tidal flow or backwater flooding from the bay side behind the island. FEMA's own mapping treats those as distinct inputs, along with heavy-rainfall drainage across a flat, low-lying surface, and a parcel-level map is the only way to see how those inputs actually apply to one lot in Wildwood.
Why Barrier Island Geography Matters for Flood Risk, in General Terms
A barrier island is, by definition, a strip of sand separating open ocean from a bay or lagoon, and Five Mile Beach, home to Wildwood, North Wildwood, Wildwood Crest, and West Wildwood, is exactly that kind of landform. Islands like this can shift, erode, and rebuild over time in response to storms and longshore currents, and the low elevation typical of barrier islands means that even a modest storm surge or an unusually high tide can push water further inland than it would on higher ground. None of that is unique to Wildwood specifically; it is a general characteristic of barrier-island geography that applies to this stretch of the Jersey Shore.
What it means in practice is that a Wildwood property's flood exposure is not something a citywide description can responsibly summarize with a single risk level. A block near the ocean-facing boardwalk, an interior block a short distance away, and a block backing onto bay or marsh frontage can carry meaningfully different flood-zone designations and different base flood elevations under FEMA's mapping, even within a city as small as 1.65 square miles. This page does not attempt to guess which category applies to any particular block or lot.
How FEMA Flood Zones Actually Work
FEMA maps flood risk through Flood Insurance Rate Maps, and the resulting zone letters describe a category of risk, not a guarantee. In general terms: zones starting with the letter V (sometimes shown as VE) mark coastal areas subject to wave action and storm surge; zones starting with A (including AE) mark areas subject to a 1-percent-annual-chance flood, commonly called the 100-year floodplain; and zone X marks areas outside that mapped high-risk floodplain, though X is not a claim of zero flood risk. Each zone can carry a different federal flood-insurance requirement and a different base flood elevation, the height to which a structure is expected to be built or elevated.
This page does not assign any of those letters to a specific Wildwood parcel, and it does not state a base flood elevation for any address in the city, because neither has been independently confirmed here at the parcel level. On a barrier island this narrow, ocean-side blocks, interior blocks, and bay-side blocks can reasonably fall into different zones with different requirements within just a few streets of one another. A citywide summary would flatten a distinction that FEMA's own mapping is specifically designed to draw parcel by parcel.
What This Page Does Not Confirm
No current FEMA flood-zone designation for any specific Wildwood parcel was confirmed in the research behind this page, and none is invented here. No current flood-insurance premium figure for this city was confirmed, and none is stated. No current Cape May County or City of Wildwood property tax rate, current New Jersey state sales tax rate, current median home price, or current active-listing count was confirmed either, beyond the 2020 census population figure of 5,157 for the city (down 3.2 percent from 5,325 in 2010), per Wikipedia. New Jersey's tax structure is also genuinely different from a no-sales-tax state, and this page does not assume any specific current rate applies.
This page also does not confirm any current (2025-2026) storm-damage, erosion, or beach-replenishment event specific to Wildwood. None of these gaps should be read as reassurance about flood risk, and none of them are filled here with a number that was not actually confirmed. They are stated directly so a reader knows exactly what this page establishes, the documented geography behind Wildwood's flood exposure and a plain-terms explanation of how zone mapping works, and what it does not: a specific zone letter, a specific premium, or a specific tax figure for any one address.
Where to Check a Specific Wildwood Address
Start with FEMA’s own Flood Map Service Center at msc.fema.gov, where an address search returns the currently effective Flood Insurance Rate Map panel for that parcel and a printable FIRMette showing the mapped zone. Given Wildwood’s barrier-island layout, it is worth checking whether the mapped zone and base flood elevation for a given address are keyed to ocean frontage, an interior block, or bay and marsh frontage on the back side of Five Mile Beach, since the source of exposure can differ block by block on an island this narrow.
From there, cross-check against Cape May County’s floodplain management resources and the City of Wildwood’s own construction office, since local floodplain ordinances can apply on top of the federal zone designation and can affect what can be built, elevated, or rebuilt on a given lot. For a formal determination, an elevation certificate, or an actual insurance quote rather than a general estimate, work with a New Jersey-licensed flood insurance agent and, for any legal question tied to a purchase, a New Jersey-licensed real estate attorney, who can pull the parcel’s actual zone and advise on that specific address.

The general description of FEMA flood-zone categories (V/VE, A/AE, and X) reflects FEMA's own published, general definitions of those zone types and is not a claim about any specific Wildwood parcel's actual mapped zone. No current FEMA flood-zone designation for any specific Wildwood parcel, no current flood-insurance premium figure, no current Cape May County or City of Wildwood property tax rate, no current New Jersey state sales tax rate, and no current median home price or active-listing count specific to Wildwood was confirmed via primary-source research this pass, and none is invented here. Confirm current flood-zone status, base flood elevation, and insurance requirements for any specific address directly through FEMA's Flood Map Service Center (msc.fema.gov), Cape May County's floodplain management resources, the City of Wildwood's construction office, and a licensed New Jersey flood insurance agent, and consult a licensed New Jersey real estate attorney for any legal question tied to a purchase, before making a purchase decision.
