Largest 8 of 12 schemes shown. Source: Flood Risk Management County Summaries & Past Flood Events, floodinfo.ie. Past-event counts derived from the OPW floodinfo.ie Past Flood Events layer. Nationally, 57 completed schemes protect over 13,640 properties, with €1.3 billion committed to flood relief under the National Development Plan. The OPW's flood maps do not designate individual properties as at risk, and since 2014 the OPW shares completed-scheme data with Insurance Ireland to support flood cover in defended areas.
Flood history also decides whether insurers will quote, see flood insurance in Ireland: the coverage gap.
