No property in an EA risk band
No property in BB8 8LY 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 BB8 or get the full picture below.
BB8 8LY gets about 1,217 mm of rain a year on average (wettest month December, 142 mm; driest April, 68 mm). That is close to the UK as a whole, which averages 1,163 mm a year.
A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well. Source: Met Office HadUK-Grid 1991–2020 (5 km grid), 1.9 km away. Average rainfall: HadUK-Grid v1.3.2, Met Office. Contains public sector information licensed under the Open Government Licence v3.0.
The ground here sits at about 132 m above sea level and falls 29 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south, 1.2 m higher.
Two mapped watercourses are about the same distance from the centre of BB8 8LY: Colne Water (about 190 m) and Swinden Clough (about 200 m), so this page cannot say which one is nearer to you.
Distances along the river are from the point on each watercourse nearest the centre of BB8 8LY. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
Because 4 recorded flood outlines mapped nearby; 90 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around BB8 8LY. 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 | Mapped flood extent | Approx. distance |
|---|---|---|
| Dec 2015 | The Green, Nelson | ~0.9 km |
| Dec 2015 | Greenfield Road, Colne | ~0.8 km |
| Dec 2015 | Burnley Road, Colne | ~0.9 km |
| Dec 2015 | Halstead Lane, Barrowford | ~1.1 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
