Parts of Drimnagh are. The OPW has mapped river 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 Drimnagh be hard to insure against flooding?

Insurers price by postcode and by the OPW record. With 21 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 Drimnagh

The Office of Public Works keeps a register of past floods. Within 2 km of the centre of Drimnagh it holds 21 events, the latest in 2016. By source: river (9), coastal/estuarine waters (1). A recorded event does not mean every street went under. It means an insurer’s model knows the town.

Most recent on file:

January 2014: Flooding at Dublin City on 07/01/2014 (coastal/estuarine waters). Buildings and carparks evacuated in Chapelizod.

Separately from past events, the OPW flood maps (CFRAM) draw modelled extents for river flooding near Drimnagh. 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.
