Not in an at-risk area

Because 233 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around M25 1NQ. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
