Is Arklow in a flood zone?

Parts of Arklow 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 Arklow be hard to insure against flooding?

Insurers price by postcode and by the OPW record. With 18 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 the OPW record says about Arklow

The Office of Public Works keeps a register of past floods. Within 2 km of the centre of Arklow it holds 18 events, the latest in 2026. By source: coastal/estuarine waters (13), turlough (1), river (1), runoff (1). A recorded event does not mean every street went under. It means an insurer’s model knows the town.

Most recent on file:

Separately from past events, the OPW flood maps (CFRAM) draw modelled extents for river and coastal flooding near Arklow. 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 report on this site checks 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.
