What the OPW record says about Stepaside

The Office of Public Works keeps a register of past floods. Within 2 km of the centre of Stepaside it holds 9 events, the latest in 2011. By source: river (4), runoff (2), low lying land (1). A recorded event does not mean every street went under. It means an insurer’s model knows the town.

Most recent on file:

October 2011: Flooding at Clonskeagh Road, Dublin 6 on 24th Oct 2011.
October 2011: Flooding at Kilgobbin Road, Stepaside, Co. Dublin on 24th Oct 2011.
April 1993: Ramore Leopardstown Road May and June 1993 (low lying land).
November 1982: School House Lane Sandyford Nov 1982 (runoff).
January 1980: Sandyford Church Jan 1980 (river). Flooding caused by builder blocking stream

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