Not in an at-risk area

Because 4 recorded floods nearby; 333 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around BN8 5BY. 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.
Warnings cover flood areas, not individual addresses.
