No property in an EA risk band
No property in BL6 7RN 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 BL6 or get the full picture below.
The ground here sits at about 114 m above sea level and falls 31 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-east, 22.6 m higher.
Because 2 recorded floods nearby; 75 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around BL6 7RN. 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 |
|---|---|---|
| Dec 2015 | Scholes Bank, Horwich | ~0.2 km |
| Oct 1992 | DOUG | ~1.0 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.
