Seawall & Bulkhead Guide: Strathmere, New Jersey
Strathmere is an unincorporated community and census-designated place within Upper Township, Cape May County, New Jersey, on the northern portion of Ludlam Island, separated from Ocean City by Corson's Inlet to the north and sharing the island with Sea Isle City to the south. Wikipedia records a total area of just 0.76 square miles (0.53 land, 0.23 water) and an elevation of only 3.3 feet above sea level, and Strathmere carries a real, informal identity as the "skinniest town in South Jersey" -- in some sections only a single block wide, narrow enough that both the Atlantic Ocean and Strathmere Bay are visible from an elevated dune vantage point. That narrowness is not a marketing line here; it is the reason a single property in Strathmere can plausibly face two different kinds of water on two different sides, ocean surf on one and calmer bay water on the other, which is a genuinely distinctive setup compared with other New Jersey markets built on this site. It also sits alongside a real, dramatic, currently active erosion crisis: in March 2026, Upper Township demolished its own Beach Patrol headquarters on Williams Avenue in Strathmere after half of the 20-year-old building was left hanging over a cliff carved by erosion. This page does not invent bulkhead heights, materials, or permit costs. It lays out why ocean-side and bay-side shoreline hardening are different questions here, what the town's active erosion emergency and the 2026 Army Corps dune project do and do not tell a property owner, and where to go for the rules this page does not know.
One Narrow Town, Two Different Shorelines
A seawall is built to absorb direct, open-water wave energy -- it is the structure standing between breaking surf and whatever sits behind it. A bulkhead is a different kind of structure for a different kind of water: typically a vertical wall of timber, vinyl, steel sheet piling, or concrete, built to hold soil in place along a shoreline that is not taking breaking waves, such as a bay, lagoon, or sheltered inlet margin.
Strathmere's genuine narrowness is what makes both questions relevant on the same island, and sometimes plausibly on the same block. Wikipedia confirms the community sits on Ludlam Island with 0.23 of its 0.76 square miles classified as water, and the "skinniest town in South Jersey" description reflects real, single-block-wide sections where the ocean and Strathmere Bay are both visible at once from high ground. A property closer to the ocean side is more likely to be dealing with dune and beachfront erosion; a property on or near the bay side is more likely to be the kind of calmer-water setting where a bulkhead, rather than a seawall, is the relevant structure. Neither this page nor any general description of the town can say which situation applies to a specific parcel -- that is a lot-by-lot question.
A Beach Patrol Building Undermined by an Erosion Cliff
The clearest, most concrete evidence that erosion is a live, active problem in Strathmere is not a projection -- it already happened. In March 2026, Upper Township demolished its own Beach Patrol headquarters on Williams Avenue in Strathmere because half of the 20-year-old building had been left hanging over a cliff formed by severe erosion. Township Committeeman Sam Palombo said at the time, "At some point it will come down, so we had to make the smart decision and get rid of it before it becomes another environmental hazard by falling into the ocean." A stretch of beach that had once required a 50-to-60-foot walk across sand was reported to be nearly gone at high tide, and officials warned that 60 to 70 percent of Strathmere's beaches could become unavailable that summer without intervention. The community was under a real, declared local state of emergency.
That is not a story about any individual seawall or bulkhead -- it is a municipal building on the ocean side of a genuinely narrow town, undermined by the same erosion forces that make shoreline hardening a serious consideration for property owners generally in Strathmere. It is real, confirmed, and specific to this community, and it is the clearest reason a Strathmere owner, on either side of the island, should take shoreline condition seriously rather than treat it as an abstract coastal-town concern.
The 2026 Army Corps Project Is a Public Dune, Not a Private Seawall
On April 30, 2026, the U.S. Army Corps of Engineers Philadelphia District awarded a $21.6 million contract to Norfolk Dredging Company for a combined Strathmere/Sea Isle City beachfill project, with Strathmere receiving the larger share by far: 1,381,000 cubic yards of sand along roughly 5,168 feet of shoreline north of Seaview Avenue, engineered into a dune-and-berm template with dune crossovers, fencing, and access paths. Construction was expected to begin in early June 2026, cost-shared 50 percent federal and 50 percent non-federal.
This is public, ocean-side infrastructure built and funded by the federal government and its non-federal partners, not a bulkhead or seawall built for an individual property. It is the primary current response to Strathmere's ocean-facing erosion problem, and a meaningful one given that Strathmere is the single largest beneficiary of the combined project by sand volume. But it says nothing about the condition, age, or permit status of any bay-side bulkhead a Strathmere property owner might already have, or need. Those remain separate structures, built and maintained separately, answering to separate rules.
What This Page Does Not Confirm
This page does not state, and does not know, any specific Strathmere or Upper Township bulkhead or seawall ordinance number, the current cost of a bulkhead permit application, or any specific height, material, or maintenance requirement tied to owning or repairing one. No such figures were confirmed in the research behind this page, and none is invented here.
This page also does not state whether the 60-to-70-percent beach-unavailability warning from March 2026 came to pass, whether the Army Corps dune project has been completed, or whether a permanent replacement for the demolished Beach Patrol headquarters has since been built or planned -- construction on the beachfill project was expected to begin in early June 2026 as of the Army Corps' own release, and this page does not claim to know its outcome. No current (2026) permanent population figure beyond the 2020 census count of 137, no current median home price, no current active-listing count, no current Upper Township or Cape May County property tax rate, and no current New Jersey state sales tax rate is stated here -- New Jersey has its own sales tax and a property-tax structure genuinely different from Delaware's. No current FEMA flood-zone designation for any individual Strathmere parcel and no specific current business name is asserted anywhere on this page.
What a Strathmere Property Owner Should Actually Ask
Given the town's genuine narrowness and the real possibility of both ocean and bay exposure on or near the same parcel, a practical first question for any Strathmere owner is simply which shoreline, or shorelines, the property actually faces -- ocean, bay, or both -- since that determines whether a dune-and-erosion conversation, a bulkhead conversation, or both apply. A second question, for any property with an existing bulkhead, is its age, material, and condition, since 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 installed.
A third question, specific to this moment, is how close a given property sits to the stretch of ocean-facing shoreline covered by the 2026 Army Corps dune project versus how much of the parcel's own erosion exposure that project actually addresses. None of these questions can be answered in general terms on a page like this one. All are property-by-property questions for Upper Township's own construction and zoning offices, the New Jersey Department of Environmental Protection, and a licensed inspector or coastal engineer who can examine the actual lot.
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 for any bulkhead or seawall work in Strathmere. Upper Township's own construction and zoning offices are the right local source for a permit application specific to a given parcel, current fees, and current inspection requirements, since Strathmere itself is unincorporated and governed as part of the township. The U.S. Army Corps of Engineers is the relevant federal authority for dredging, navigation, and federally authorized shore-protection work -- including the 2026 Strathmere/Sea Isle City beachfill and dune project -- in the same waters.
For anything specific to an actual lot -- whether an existing bulkhead 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 Upper Township 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 April 30, 2026 U.S. Army Corps of Engineers $21.6 million beachfill contract to Norfolk Dredging Company, Strathmere's 1,381,000-cubic-yard share along roughly 5,168 feet north of Seaview Avenue, the dune-and-berm-with-crossovers design, and the expected early-June-2026 construction start are sourced from the Army Corps of Engineers Philadelphia District's own official news release. This page does not state any specific Strathmere or Upper Township bulkhead or seawall ordinance number, current permit cost, or maintenance requirement, none of which was confirmed in this research pass; no such figure is invented here. This page also does not confirm whether the beach-unavailability warning came to pass, whether the Army Corps project has been completed, or whether a permanent Beach Patrol facility has since been built. No current population beyond the 2020 census count of 137, median home price, active-listing count, property tax rate, or New Jersey sales tax rate specific to Strathmere was confirmed via primary-source research this pass. Confirm current bulkhead and seawall permitting requirements directly with Upper Township's construction and zoning offices 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 Strathmere property.
