What this layer shows

SEPA's future flood map for surface water and small watercourses: the medium likelihood extent, a 0.5% (1 in 200) chance in any year, under SEPA's "2070 RCP 8.5, 50th percentile" rainfall scenario. Over ten million shapes nationally, so it draws close in. A modelled scenario, not a site assessment.
