Not in an at-risk area
CM22 7SG 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 CM22 or get the full picture below.
The ground here sits at about 54 m above sea level and falls 20 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-north-east, 17.6 m higher.
Because 6 recorded floods nearby; 96 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around CM22 7SG. 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.
