Is Raheny in a flood zone?

Parts of Raheny are. The OPW has mapped river and coastal flood extents within about 1.5 km of the town centre. A zone covers streets, not the whole town, so the answer for one house depends on where it stands. The report checks the exact Eircode against the 1 in 10, 1 in 100 and 1 in 1000 year extents.

Will a house in Raheny be hard to insure against flooding?

Insurers price by postcode and by the OPW record. With 5 recorded events within 2 km, expect questions on the proposal form and possibly a flood exclusion on some streets. Ask the seller for their current policy schedule: if flood is excluded, you will inherit that problem.

What does the paid report add for a house in Raheny, Dublin?

It puts the Eircode point against every OPW flood extent, lists recorded floods within 500 m with dates and OPW notes, checks GSI groundwater flood maps and coastal erosion, and ranks the result against the other twenty-eight checks (radon, BER, planning, knotweed, title, sewer and more) for that one address.

What the OPW record says about Raheny

The Office of Public Works keeps a register of past floods. Within 2 km of the centre of Raheny it holds 5 events, the latest in 2021. By source: runoff (2), other (1). A recorded event does not mean every street went under. It means an insurer’s model knows the town.

Most recent on file:

December 2021: Flooding at Kilbarrack on 02/12/2021. Media report of road flooded at junction of Kilbarrack Road and Howth Road
November 2017: Flooding at Clontarf on 22/11/2017 (other). Clontarf Road, impassable at the Mount Prospect Avenue junction
August 2004: Mount Prospect Ave Clontarf August 2004 (runoff).
November 1982: Grange Road Donaghmede Nov 1982 (runoff).
June 1963: Howth Road Harmonstown June 1963.

Separately from past events, the OPW flood maps (CFRAM) draw modelled extents for river and coastal flooding near Raheny. A house inside the 1 in 100 year river extent, or the 1 in 200 year coastal extent, will usually need a flood-specific conversation with the insurer before you can draw down a mortgage.

What to do before bidding on a house here

Look the exact address up on the OPW map, not the town. Two houses on the same road can sit on opposite sides of an extent line. Ask the seller in writing whether the house or garden has ever flooded and whether a flood claim was made. Ask for the current insurance schedule. If the house is inside an extent, get a quote before going sale agreed: some insurers decline outright, and the bank will not lend without cover.

The free snapshot on this site flags flood for one Eircode in about a minute. The paid report adds the distance to each recorded event, which extents the point falls in, and the GSI groundwater map, all with links to the source so a solicitor can rely on them.
