Monmouth Beach, New Jersey: A Shared Seawall and Waterfront Hardening on Two Fronts

A Shared Seawall: The Same Structure That Runs Through Sea Bright Extends Here

The seawall documented along neighboring Sea Bright's oceanfront does not stop at the borough line between the two towns. It continues into Monmouth Beach's own shoreline as the same continuous structure. That wall dates to the 1870s, runs approximately five miles along the coast, and stands roughly 18 feet high overall, with 6 to 8 feet of that typically visible above ground on the landward side. It is shared regional infrastructure between Sea Bright and Monmouth Beach, not two separate walls that happen to look alike.

Sea Bright's own stretch of that wall is currently the subject of a specific, unresolved $35 million funding debate over filling gaps in it, involving Sea Bright's own town officials and environmental advocates. That debate concerns Sea Bright's stretch of the structure specifically, and this page does not repeat it in detail here -- readers who want that full history should look to Sea Bright's own coverage of it. What matters for Monmouth Beach is more straightforward: the same physical wall extends into this town's shoreline too, and any property owner along the Monmouth Beach stretch of it should understand it as part of one continuous system rather than a separately built local structure.

Ocean on One Side, River on the Other: A Two-Front Water Exposure

Monmouth Beach is small by land area -- 2.07 square miles total, but only 1.04 square miles of that is actually land. The remaining 1.03 square miles, 49.81 percent of the town's total area, is water, one of the higher water percentages of any Jersey Shore community. The Atlantic Ocean borders the town to the east and the Shrewsbury River borders it to the northwest, so Monmouth Beach faces moving water on two separate sides rather than one.

That dual exposure is exactly why waterfront hardening is a two-front concern here. A property facing the ocean side deals with direct wave energy and storm surge; a property facing the Shrewsbury River side deals with a different set of pressures, including tidal flow, wake action, and river-driven flooding that behaves differently from ocean surge. Anyone evaluating a specific waterfront property in Monmouth Beach should first determine which side of the town's geography that parcel actually faces, since the protection and maintenance needs are not identical on the two sides.

Hurricane Sandy and Monmouth Beach: What Is Confirmed

Monmouth Beach was among the Jersey Shore communities affected by Hurricane Sandy in October 2012, with documented damage to multiple homes in the borough. No itemized, townwide dollar total for that damage is confirmed in available research, and none is invented here. What is clear is that a town with this much water exposure on both an ocean side and a river side has a real, demonstrated history of storm vulnerability, which is part of why bulkhead and seawall condition are an ongoing, practical concern for property owners here rather than a hypothetical one.

General Maintenance Guidance for Bulkhead and Seawall Owners

Waterfront property owners along either the ocean or river side of Monmouth Beach -- whether behind a homeowner-installed bulkhead, a private seawall, or property adjacent to the larger shared regional seawall -- should expect ongoing, recurring maintenance rather than a one-time installation. Wood bulkheads are vulnerable to marine borer damage and rot near the waterline; steel sheet piling can corrode where it meets salt water and open air together; and concrete or stone structures can develop cracking and joint failure over decades of tidal cycling and freeze-thaw stress in a winter climate like New Jersey's.

A periodic professional inspection -- checking for leaning, gaps behind the wall where backfill has washed out, cracking, and corrosion at the waterline -- is standard practice for any waterfront structure, whether it is a small residential bulkhead or a stretch of larger regional seawall. Repair, replacement, or new bulkhead construction along New Jersey's tidal waterfront is also generally subject to state and sometimes federal permitting requirements, so an owner planning any such work should expect to coordinate with the appropriate state environmental agency and the borough before starting, rather than treating it as a simple property-line repair.

What Is Confirmed, What Remains Unresolved, and Where to Get Current Answers

What is documented: Monmouth Beach totals 2.07 square miles, 49.81 percent of it water, bordered by the Atlantic Ocean to the east and the Shrewsbury River to the northwest; the same seawall documented on Sea Bright's oceanfront, dating to the 1870s, roughly five miles long and about 18 feet high overall with 6 to 8 feet visible above ground, extends into Monmouth Beach's own shoreline; and the borough was affected by Hurricane Sandy in 2012, with damage to multiple homes confirmed but no itemized townwide total available.

What is not confirmed, and is not invented here: any exact current (2026) home-price, property-tax-rate, or flood-insurance figure for Monmouth Beach beyond a 2023 Zillow average of $974,409 that is explicitly dated rather than current; a completion date for Sea Bright's separate gap-filling project on its own stretch of the shared wall; and any townwide itemized dollar total for Monmouth Beach's own Sandy damage. Anyone evaluating a specific waterfront property here should get a current flood-zone determination from FEMA's Flood Map Service Center, ask the borough directly about the condition of the seawall or bulkhead nearest that property, and consult a New Jersey-licensed coastal engineer and a real-estate attorney familiar with shoreline-protection assessments before making a purchase decision.
