Seawall & Bulkhead Guide: Block Island, RI

Who Owns and Maintains a Seawall or Bulkhead Here

As a general matter of coastal property, true across Rhode Island and most other coastal markets, a seawall, bulkhead, or riprap revetment installed on an individual waterfront lot is understood to be that property owner's structure -- not a public asset maintained by the town of New Shoreham or the State of Rhode Island. The owner is generally the one who arranged for the structure's installation, and the owner is generally the one expected to monitor its condition, repair it, and eventually replace it as it ages. That is a general principle about how private shoreline armoring works, not a claim about a specific New Shoreham ordinance or a documented Block Island maintenance schedule, neither of which was confirmed in research for this page.

This distinction matters most when a property is marketed with an existing seawall or bulkhead already in place. Its presence does not mean a public agency inspects it, insures its performance, or is committed to rebuilding it if it fails -- that risk and that responsibility generally sit with whoever owns the lot, before and after any sale. Anyone evaluating a specific Block Island waterfront property with an existing structure should have it assessed directly by a marine contractor or engineer rather than assuming its condition, age, or adequacy from general reputation alone.

Rhode Island CRMC's Role Over Coastal Construction

Rhode Island's Coastal Resources Management Council (CRMC) is the state agency with regulatory authority over coastal construction and shoreline alteration across Rhode Island's coastline generally, and it maintains a dedicated coastal erosion program relevant to Rhode Island shoreline properties, including Block Island. Structurally, that means a new seawall, bulkhead, or a significant repair to an existing one on Block Island is the kind of shoreline construction that falls within CRMC's jurisdiction as a matter of how Rhode Island regulates its coast statewide -- the same way any other Rhode Island waterfront community's shoreline construction is subject to CRMC's authority.

What this page does not do is state a specific Block Island permit process, application timeline, fee schedule, or approval standard for a private seawall or bulkhead, because no such island-specific detail was confirmed in research for this page. CRMC's actual current requirements, application steps, and any fees for a given property and a given proposed structure need to come directly from CRMC itself, not from a general statement of its statewide role. Any waterfront owner or buyer planning new shoreline construction or a repair should confirm the current process directly with CRMC before assuming a cost, a timeline, or an outcome.

Why This Is a Live Question Right Now: URI's 2026 Erosion Research

Shoreline-structure decisions on Block Island are not a settled, static topic this year. The University of Rhode Island's Graduate School of Oceanography and its Coastal Institute are running an active, 2026-dated research partnership with the island, working through more than a century of coastal-change data specifically to help the town decide what to protect along its shoreline -- reported by URI's own news office in May 2026, the Boston Globe on June 8, 2026, and the Block Island Times. That is a genuinely current, ongoing research effort, not a historical study being cited after the fact.

Because that research is explicitly aimed at informing what the island protects and how, it sits directly upstream of the same kinds of questions a waterfront owner faces about an individual seawall or bulkhead: what stretch of shoreline is eroding fastest, what kind of protection makes sense where, and how the island's approach might evolve. The study's conclusions and any resulting New Shoreham policy were not confirmed as of this page's research and should not be assumed -- the research was still underway as of the 2026 reporting. The honest takeaway for a buyer is that this is a live, evolving conversation on Block Island right now, and shoreline-structure expectations here are more likely to shift in the near term than in a market where erosion policy has not been an active, current news story.

What This Means Before You Buy

Put together, a realistic checklist for a Block Island waterfront buyer looks like this: have any existing seawall, bulkhead, or riprap on a specific lot assessed directly by a marine contractor or engineer rather than assumed from its presence alone; confirm CRMC's current permitting requirements, process, and any fees directly with CRMC for any new construction or repair rather than assuming a generic coastal-permitting timeline; and follow the URI Graduate School of Oceanography and Coastal Institute's ongoing 2026 research, along with any resulting New Shoreham town discussion, since it is actively shaping how this specific island thinks about what shoreline to protect. Given Block Island's ferry-only access and its status as a single small town rather than a large coastal jurisdiction, shoreline-structure decisions here are also inseparable from decisions the town itself may make about its coast as the research progresses -- one more reason to treat this as a current, moving topic rather than one with a fixed, final answer.
