Seawalls and Bulkheads in Ship Bottom, New Jersey
Ship Bottom is a small municipality: 0.99 total square miles, and of that, 0.71 square miles of land against 0.28 square miles of water. That ratio matters for anyone thinking about shoreline protection here, because it means water edge is not a minor feature of this borough's geography — it is close to a quarter of the town's entire footprint, on the bay side of a barrier island whose ocean side already gets most of the attention. This page does not state a current bulkhead or seawall permit cost, a specific construction standard, or an engineering requirement for Ship Bottom, because none was confirmed during this research pass, and getting that detail wrong could cost a property owner real money or a failed inspection. What follows is the real, documented context that makes shoreline protection structures a genuinely relevant topic here, plus exactly where to get current, authoritative answers: Ship Bottom's own Construction Office and the New Jersey Department of Environmental Protection (NJ DEP).
A Small Town Where the Water Edge Is a Real Share of the Map
Ship Bottom sits on Long Beach Island (LBI) in Ocean County, at the narrow northern end of the island, and is known locally as the "Gateway to Long Beach Island" because Route 72, via the Manahawkin Bay Bridge, is the sole road connection onto LBI, and that road runs directly through the borough. Its total area is 0.99 square miles, split between 0.71 square miles of land and 0.28 square miles of water. That water figure is not a rounding error — it reflects real bay frontage on the western side of a town that most visitors think of only in terms of its ocean beach.
A borough this compact, with water making up close to 28% of its total area, is a place where bayside bulkheads and any ocean or inlet-facing shore-protection structures are not a side issue for a relatively small number of waterfront owners. They are part of how a meaningful share of the town's edge is held in place, full stop. That is the honest reason this topic gets its own page here, not because this research turned up a specific Ship Bottom bulkhead ordinance or engineering spec, because it did not.
What Bulkheads and Seawalls Actually Are, in General Terms
In general shore-protection terminology, a bulkhead is a retaining wall built at or near the water's edge, primarily meant to hold back land and prevent soil erosion behind it, often doing double duty as a bank between a developed lot and open water. A seawall is typically a more substantial structure built to directly absorb and deflect wave energy, usually where a property faces more direct ocean or open-bay wave action rather than the calmer edge conditions a bulkhead is more suited to. Both are long-standing, common categories of shoreline hardening used up and down the New Jersey coast and on barrier islands generally.
This page will not describe a specific material, height, footing depth, or permitted design for a bulkhead or seawall in Ship Bottom, because current construction standards, permit requirements, and any NJ DEP coastal-zone or waterfront-development rules that would apply to a specific Ship Bottom parcel were not confirmed in this research pass, and those rules are also the kind that change and vary by exact location. Anyone planning new construction, repair, or replacement of a shoreline structure in Ship Bottom needs current, parcel-specific answers from Ship Bottom's own Construction Office and from the NJ DEP, not a general description like the one above.
Hurricane Sandy: Ship Bottom Was the Hardest-Hit Town on All of LBI
The single clearest documented reason shoreline protection is a real conversation in Ship Bottom, rather than an abstract one, is Hurricane Sandy in October 2012. Per New Jersey Department of Community Affairs data, compiled by NJ Spotlight and cross-referenced with U.S. Census figures, Ship Bottom was the hardest-hit municipality on all of Long Beach Island, with 46% of its housing stock damaged. That works out to 829 total homes damaged: 752 with minor damage, 38 with major damage (losses of $8,000 to $28,800), and 39 with severe damage (losses exceeding $28,800). Just over 40% of rental units were also damaged, 110 total units, 44 of them with major damage, and 157 local businesses were affected by the storm.
That comparative figure is worth sitting with against Ship Bottom's LBI neighbors: Surf City saw 27% of its housing stock damaged, Beach Haven 10%, Long Beach Township 9%, Harvey Cedars 5%, and Barnegat Light less than 1%. This research did not turn up, and this page will not invent, a specific engineering explanation for why Ship Bottom took the worst of it beyond its low elevation and its bayside and oceanside exposure at the narrow northern end of the island. No dune height, levee design, or bulkhead-failure explanation beyond that general geography was confirmed, so none is asserted here. What is confirmed is the outcome: this is documented as the single worst Sandy housing-damage record on LBI, in a town where nearly three in ten square miles of total area is water.
Full Flood-Hazard Designation and the CRS Discount
Ship Bottom participates in FEMA's Community Rating System (CRS) as part of the National Flood Insurance Program (NFIP), and that CRS participation earns residents a 15% reduction in flood insurance premiums. The entire municipality sits within the 100-year floodplain and is designated a Special Flood Hazard Area by FEMA — not a portion of the borough, all of it. Properties in a Special Flood Hazard Area face a 26% chance of experiencing flood damage over the life of a 30-year mortgage, per FEMA's own standard risk framing; that is a general FEMA statistic cited in Ship Bottom's own materials describing its flood risk, not a probability calculated specifically for Ship Bottom parcels.
FEMA has produced Base Flood Elevation maps for the borough, available online and at the Construction Office, along with additional maps depicting future coastal hazards and historical flooding events. A full-borough Special Flood Hazard Area designation, combined with the documented Sandy damage record above, is the honest, sourced backdrop against which any conversation about bayside or oceanfront shore protection in Ship Bottom should happen. It is not, on its own, a statement about what any specific bulkhead or seawall project currently requires.
Where to Get Current, Authoritative Answers
For anyone who owns or is considering buying waterfront property in Ship Bottom, the two places to get current, binding answers about bulkhead and seawall construction, repair, replacement, permitting, and cost are Ship Bottom's own Construction Office, which maintains the Base Flood Elevation maps referenced above and administers local construction permitting, and the New Jersey Department of Environmental Protection, which regulates coastal and waterfront construction activity under state law. Neither of those offices was the source of a specific figure or standard cited in this article, and that is deliberate: this page's job is to explain why the topic matters here, not to guess at what a specific office would tell a specific property owner.
A local real estate agent familiar with Ship Bottom's bayside blocks, and a contractor licensed for New Jersey coastal shoreline work, are the other two practical resources worth involving before budgeting any bulkhead or seawall project, since both permitted scope and cost can vary block by block on a barrier island this size.
Adding It Up: What Is Real, and What We Will Not Invent
What is confirmed and real here: Ship Bottom's total area is 0.99 square miles, 0.71 square miles of land and 0.28 square miles of water, on Long Beach Island in Ocean County, reached solely via Route 72 and the Manahawkin Bay Bridge; Ship Bottom was documented as the hardest-hit municipality on all of LBI during Hurricane Sandy, with 46% of its housing stock damaged (829 homes: 752 minor, 38 major, 39 severe), compared with 27% in Surf City, 10% in Beach Haven, 9% in Long Beach Township, 5% in Harvey Cedars, and under 1% in Barnegat Light; the entire borough is designated a Special Flood Hazard Area by FEMA and sits within the 100-year floodplain; Ship Bottom participates in FEMA's CRS program, earning residents a 15% flood-insurance discount; and Base Flood Elevation maps for the borough are maintained by, and available at, the Construction Office.
What we could not find, and will not fill in with an invented figure: a current Ship Bottom bulkhead or seawall permit cost, a specific construction material or engineering standard, a current NJ DEP coastal-permitting requirement or timeline, or an engineering explanation for why Ship Bottom's Sandy damage exceeded its LBI neighbors beyond its documented low elevation and bayside/oceanside exposure. Get current bulkhead and seawall permitting requirements, standards, and cost estimates directly from Ship Bottom's Construction Office and the New Jersey Department of Environmental Protection before budgeting any shoreline project.
