No property in an EA risk band
No property in DN41 8SD appears in the Environment Agency's rivers-and-sea flood-risk dataset. That dataset covers one of five flood sources. It is area-level, it covers rivers and the sea only, and it is never proof a place cannot flood — surface water, groundwater, sewers and reservoirs are assessed separately. See the at-risk postcodes in DN41 or get the full picture below.
The ground here sits at about 18 m above sea level and falls 14 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south-west, 6.2 m higher.
Because 5 recorded floods nearby; 106 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around DN41 8SD. 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.
