Read this before relying on these figures. Northern Ireland's own flood maps are not published under an open licence, so the band above is modelled, not DfI's official mapping. The model is undefended — it does not account for flood defences, so a defended town can read as more exposed than DfI's own map shows — and it covers rivers only. For a property-level answer, use Flood Maps NI.
