Seawall & Bulkhead Guide: Bethany Beach, DE
Bethany Beach faces a simpler shoreline question than some of its Delaware neighbors. The town sits directly on the Atlantic Ocean coast in Sussex County, on a compact 1.16 square miles of land, with a single ocean-facing shoreline rather than the ocean-and-bay double exposure that towns squeezed onto a narrower barrier strip have to account for. That single-shoreline geography means the real shoreline-management question for a Bethany Beach property owner is not which of two water bodies a lot faces, but how the town itself has actually managed its one ocean-facing edge over time. The town's own documented history points toward beach nourishment and dune-building rather than a confirmed hard seawall, and that history, along with the general seawall-versus-bulkhead distinction and where to get a site-specific answer, is what this page lays out.
One Shoreline, Not Two
Bethany Beach's entire town footprint faces the open Atlantic. That is a meaningfully different starting point than a town split between an ocean side and a bay or inlet side, because it means there is only one type of wave and storm exposure to plan around, not two. A seawall, or on an open ocean coast more often a reinforced dune system built up with sand fencing and beach grass, is designed to absorb or block direct wave energy from the open ocean. A bulkhead is a different kind of structure, typically timber, vinyl, or steel sheet piling, built mainly to retain soil and hold a stable edge along calmer, sheltered water such as a bay, canal, or marina frontage. Because Bethany Beach does not have that second, sheltered-water frontage within town, the bulkhead half of that distinction is less likely to apply to an ocean-facing Bethany Beach lot, though it is still worth understanding both terms before assuming which one, if either, is relevant to a given property.
A Real Storm History, and a Nourishment-First Response
Bethany Beach has a genuinely severe, well-documented storm history bearing on this question. The town's own account describes the Ash Wednesday Storm of March 1962 as "the most destructive storm in Bethany Beach's history," with 80 mph winds and 30-foot waves that destroyed beachfront structures dating back to the town's founding era, along with its bowling alley, as part of more than $50 million in damage along the Delaware-Maryland-Virginia peninsula. Hurricane Gloria, in September 1985, later badly damaged the town's boardwalk. What stands out is how the town responded to erosion in the decades that followed: rather than a documented hard seawall, the record points to a roughly $20 million federally funded beach replenishment project completed in 2008-2009, which built up new dunes along the shoreline. Those dunes proved controversial locally for blocking ocean views from beachfront properties, and Tropical Storm Ida struck in November 2009 and destroyed most of the newly built dunes not long after the project finished.
That sequence is a useful data point in itself. It shows a town whose documented approach to shoreline management, at least in its most recent well-sourced episode, has leaned on soft engineering, sand and dune replenishment, rather than on a hard armoring structure like a seawall or bulkhead. That is not the same as saying no hard structure exists anywhere on a Bethany Beach property; it simply reflects what this research was able to confirm about the town's general pattern.
What This Research Could Not Confirm
This research did not turn up a confirmed, named seawall or bulkhead structure tied to any specific Bethany Beach parcel, nor a permit history or a construction or repair cost figure for any such structure in town. It also did not confirm the current status of dune or beach-nourishment coverage beyond the 2008-2009 project and its loss to Tropical Storm Ida later that year; whatever has been rebuilt or maintained since then was not independently verified in this pass. None of that is guessed at here, because a wrong structure, a wrong permit status, or an invented cost figure is exactly the kind of thing a property owner should not plan around.
Where to Get a Site-Specific Answer
The Delaware Department of Natural Resources and Environmental Control (DNREC), through its Shoreline and Waterway Management section, regulates shoreline armoring, dune work, bulkheads, and seawalls along Delaware's ocean coast, including Bethany Beach. That is the right first call for current permitting rules that would apply to a Bethany Beach property today. For anything specific to a given lot, whether that means assessing an existing structure, evaluating dune condition, or deciding whether any hardening is appropriate at all, the sounder next step is a licensed Delaware coastal engineer, who can look at that particular property and recommend what actually fits it. Nothing on this page is engineering, permitting, or legal advice.

Bethany Beach's location directly on the Atlantic Ocean coast in Sussex County, Delaware, with a total land area of 1.16 square miles, is drawn from this site's own Bethany Beach research file. The Ash Wednesday Storm of March 1962, described by the town's own history as "the most destructive storm in Bethany Beach's history" (80 mph winds, 30-foot waves, destruction of founding-era beachfront structures and the town's bowling alley, part of $50 million-plus in peninsula-wide damage), and Hurricane Gloria's 1985 damage to the boardwalk, are both drawn from the Town of Bethany Beach's own official history. The 2008-2009 roughly $20 million federally funded beach replenishment project, the resulting dunes that drew local criticism for blocking ocean views, and Tropical Storm Ida's destruction of most of those dunes in November 2009, are documented in the same research file. Delaware DNREC's role in regulating shoreline armoring, dunes, bulkheads, and seawalls along Delaware's coast is a general regulatory fact, not a Bethany Beach-specific finding. No confirmed existing seawall or bulkhead structure, permit record, or cost figure tied to a specific Bethany Beach parcel was located in this research, and none is invented here; the same is true of any current dune or nourishment project status beyond the 2008-2009/Tropical Storm Ida sequence. Confirm current permitting requirements directly with Delaware DNREC's Shoreline and Waterway Management section, and get any site-specific structural question answered by a licensed Delaware coastal engineer, before planning work on a Bethany Beach property.
