'Relocation of some communities' urged due to rising sea levels

# What the report says

Peter Thorne, chair of the council's climate adaptation committee, framed the issue as one that will fall to future generations if action is delayed. The council calls for a national coastal management plan that accepts some shorelines cannot be defended indefinitely and that prepares for managed retreat in suitable places.

# Where damage is visible now Residents in Rosslare reported worsening erosion after recent storms. The report flags hundreds of at‑risk ancient forts, including sites on the Copper Coast in Waterford. The article notes fears among residents that some properties may not survive another winter in exposed areas.

# Planned relocation and policy suggestions The council recommends identifying properties at high risk and planning relocations in advance rather than responding case by case. Thorne said Ireland could use the precedent of relocating a small number of homes for the MetroLink project as a model: compensate residents and move them to safer locations rather than spending large sums to protect every vulnerable stretch of coast.

The council warned against allowing new homes to be built 'in harm's way' and urged the state to decide where to defend and where to withdraw. Thorne said protecting everything would be impractical and could worsen problems elsewhere.

# Sea‑level scenarios and long‑term risk The report references multi‑generation sea‑level rise scenarios. Thorne said one to two metres of rise could occur within two or three generations and discussed a hypothetical 10‑metre rise to illustrate the limits of coastal protection—he said such a rise would overwhelm the ability to protect major cities, including Dublin, Cork, Galway, and Waterford.

# Financial and insurance implications The report documents an insurance access problem: roughly 5% of buildings in Ireland have limited access to flood insurance. More than half of that protection gap is concentrated in Co Dublin, Cork, Louth, Clare, and Kildare. The council warns rising premiums, higher excesses, restricted cover, and insurer withdrawal are already affecting property owners in flood‑ and erosion‑prone areas.

# Trade‑offs and costs Thorne compared two approaches: spending tens of millions to protect a single stretch of coastline versus compensating and relocating residents. He argued that compensation and planned relocation could be more sensible and avoid creating larger problems elsewhere.

# Practical implications for communities Communities on soft‑sediment coastlines should expect continued change and increased storm impacts. Local authorities and the state are being urged to develop clear plans that map vulnerability, set relocation triggers, and allocate funding for compensation and resettlement.

# What to watch next Look for government response on a national coastal management plan, any pilot relocation schemes, changes to planning rules for coastal development, and updates to flood‑insurance availability or state supports tied to at‑risk properties.
