What the OPW record says about Blanchardstown
The Office of Public Works keeps a register of past floods. Within 2 km of the centre of Blanchardstown it holds 6 events, the latest in 2002. By source: river (4), 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:
- November 2002: M50 at the N3 Interchange Nov 2002 (runoff). Remedial measures to Road drainage have been undertaken since flooding occurred.
- November 2002: Tolka Navan Road Adj to Tolka Valley Park Nov 2002 (river).
- November 2002: Tolka River Pinebrook Hartstown Nov 2002 (river). Surface water ditches surcharged in 2000 turning park into a lake and flooding houses in Pinebrook. Subsequent remedial works have been carried out.

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.

Questions people ask
- Is Blanchardstown in a flood zone?
- The OPW has not published modelled flood extents within 1.5 km of the centre of Blanchardstown. That is not the same as no risk: 6 past floods are on record nearby. Check the exact house, not the town.
- Will a house in Blanchardstown be hard to insure against flooding?
- Insurers price by postcode and by the OPW record. With 6 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 Blanchardstown, 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.
