Not in an at-risk area
CO9 4BD has no properties in any Environment Agency recorded flood-risk band. That is good news — but it is area-level and never proof a place cannot flood (surface-water and sewer flooding are assessed separately). See the at-risk postcodes in CO9 or get the full picture below.
The ground here sits at about 55 m above sea level and falls 19 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south-east, 15.0 m higher.
Because 4 recorded floods nearby; 95 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around CO9 4BD. 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.
| Date | Recorded flood | Approx. distance |
|---|---|---|
| Jan 2009 | 2009 Flood Outline | ~25.1 km |
| Oct 2001 | 2001 Flood Outline | ~17.0 km |
| Jan 1968 | 1968 September Flood Outline | ~16.7 km |
| Feb 1947 | 1947 Flood Outline | ~23.8 km |
EA Recorded Flood Outlines — absence of a record never proves a place has not flooded. The full report tests whether any extent covered the exact spot.
