Coastal Insurance on Block Island: What's Actually Documented
Block Island is a ferry-only community twelve miles off the Rhode Island coast, comprising the entire town of New Shoreham, sitting fully exposed to Atlantic wind, waves, and storm surge with no bridge and no mainland fire or utility backup in an emergency. Insuring property here starts with the same federal program that applies to shoreline property everywhere in the US -- the National Flood Insurance Program (NFIP) -- layered on top of Rhode Island's own Coastal Resources Management Council (CRMC), which maintains a dedicated coastal erosion program relevant to shoreline properties statewide, including Block Island. This page also covers a genuinely current, still-unfolding story: a 2026 University of Rhode Island Coastal Institute research partnership studying over a century of Block Island's coastal change to help the town decide what to protect, which is why erosion is a live, actively discussed topic here right now rather than settled history. This page does not state a specific FEMA flood zone designation, a premium figure, an insurer name, or any conclusion from the still-ongoing URI research -- none of that was confirmed via full-text sourcing this session, and inventing any of it would be worse than disclosing the gap. Nothing here is insurance, legal, or financial advice; talk to a Rhode Island-licensed insurance agent before you buy, renew, or budget for coverage on any Block Island property.
What This Page Can and Cannot Tell You
This page can tell you, with good confidence, that Block Island is a ferry-only, twelve-mile-offshore Atlantic barrier-type island making up the whole of New Shoreham, RI; that NFIP flood insurance is the federal baseline coverage relevant to shoreline property here as it is everywhere in the US; that Rhode Island's CRMC maintains a dedicated coastal erosion program applicable to shoreline properties statewide, including Block Island; and that URI's Graduate School of Oceanography and Coastal Institute are running an active, 2026-dated research partnership studying over a century of the island's coastal change. It cannot tell you Block Island's specific FEMA flood zone designation for any given parcel, a specific flood or homeowners insurance premium, a specific carrier's willingness or refusal to write coverage on the island, any non-renewal statistic, or any conclusion or recommendation from the URI research, since that work is still ongoing as of the reporting this page relies on. None of those unconfirmed specifics appear anywhere on this page as stated fact.
NFIP Flood Insurance: The Federal Baseline
The National Flood Insurance Program is the standard federal flood coverage available to eligible property owners in participating communities across the US, and it is the natural starting point for any conversation about insuring shoreline property on a fully ocean-exposed island like Block Island. Whether a specific property sits in a high-risk zone, what its base flood elevation is, and how NFIP rating applies to it all depend on current FEMA flood mapping for that individual parcel -- information a licensed agent can pull and walk through for a specific address far more reliably than a general research page can. This page does not state a flood zone designation for the island or any part of it, because doing so without a verified, address-specific source would risk stating something false.
Rhode Island CRMC's Coastal Erosion Program
Rhode Island's Coastal Resources Management Council (CRMC) maintains a dedicated coastal erosion program and page addressing shoreline erosion for coastal properties across the state, Block Island included. That a state coastal management agency runs a standing erosion program at all is itself a useful signal for a prospective buyer: erosion management on Rhode Island's ocean-facing shoreline is treated as an ongoing regulatory and planning matter, not a one-off concern, and CRMC is the relevant state body to consult about setback rules, permitting, and erosion-related building or shoreline-protection requirements before purchasing or building on any Block Island parcel. This page does not restate CRMC's specific setback distances, permit rules, or erosion-rate figures, since those were not independently verified via full-text sourcing this session -- check CRMC's own materials directly, or ask a licensed agent or local contractor familiar with current CRMC requirements.
A Live Story: The 2026 URI Coastal Erosion Research Partnership
As of 2026 reporting from the Boston Globe and the Block Island Times, the University of Rhode Island's Graduate School of Oceanography and its Coastal Institute are running an active research partnership with the island, working through over a century of historical coastal-change data to help New Shoreham decide what to protect along its shoreline. This is genuinely current, ongoing work, not a concluded study -- its findings and any resulting town policy had not been finalized or independently confirmed as of the reporting this page draws on, and this page deliberately does not invent or anticipate what the research will conclude. What it does tell a prospective buyer is that erosion on Block Island is currently receiving serious, sustained scientific and municipal attention, which is exactly the kind of live context worth being aware of, and worth asking a local agent or the town about directly, before assuming a given shoreline parcel's exposure is static or already fully understood.
A Fully Exposed, Ferry-Only Market: Why It Matters for Coverage
No source found this session named a specific insurer's rules for Block Island or confirmed a specific non-renewal pattern here, and this page does not invent one. That said, it is a reasonable, hedged inference -- not a fabricated market rule -- that insuring shoreline property on a ferry-only Atlantic island with no bridge tends to involve more underwriting scrutiny than comparable mainland coverage: fewer carriers tend to compete actively for business on small, hard-to-access islands, claims adjusting and repair logistics are complicated when materials, contractors, and adjusters all have to arrive by boat, and insurers generally underwrite more cautiously in fully ocean-exposed locations with an active, standing state erosion program and current university research attention. None of that is a specific carrier policy, premium figure, or flood zone designation; it is the kind of market dynamic a Rhode Island-licensed agent working this specific area can confirm, refine, or correct based on what is actually happening in the market today.
Get a Quote From a Rhode Island-Licensed Agent
Given the combination of full Atlantic exposure, ferry-only access, an active CRMC erosion program, and a currently ongoing university erosion study, the single most useful step for any prospective Block Island buyer is to get an actual quote directly from a Rhode Island-licensed insurance agent before assuming anything about cost, coverage, or availability. Ask specifically about NFIP flood coverage and how it applies to the property in question, ask how the agent's carriers approach fully exposed, ferry-only island risk, ask what CRMC permitting or setback issues might affect the parcel, and ask what documentation -- an elevation certificate, current FEMA flood zone status, a recent survey -- the agent needs to quote accurately. Treat every general statement on this page, and on any other site, as background for that conversation, not a substitute for it; no specific premium, flood zone designation, or insurer name is stated here because none was confirmed this session, and a real quote from a licensed professional is the only reliable way to get current, property-specific numbers.

This research pass relied substantially on WebSearch results rather than fully fetched primary-source pages for several items this session, a disclosed tool-access limitation. No specific FEMA flood zone designation, insurance premium figure, insurer name, non-renewal statistic, or URI research conclusion is stated anywhere on this page, because none could be confirmed against a verified source this session -- where a figure or finding could not be verified, this page discloses the gap rather than inventing one. Block Island's erosion picture and the URI research partnership are both active and evolving; get a quote and current information directly from a Rhode Island-licensed insurance agent before making any purchase, coverage, or budgeting decision. Nothing on this page is insurance, legal, or financial advice.
