No property in an EA risk band
No property in NG34 8HD 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 NG34 or get the full picture below.
NG34 8HD gets about 608 mm of rain a year on average (wettest month October, 61 mm; driest March, 37 mm). That is 48% drier than 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), 2.7 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 61 m above sea level and falls 13 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-west, 0.6 m higher.
The river map has no watercourse within 1 km of the centre of NG34 8HD.
That means this spot is not on the river map, not that there is no water here: Ordnance Survey’s river map (OS Open Rivers) leaves out small streams, ditches and culverts. Contains OS data © Crown copyright and database rights 2026.
Because 1 recorded flood outline mapped nearby; 15 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around NG34 8HD. 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 2013 | LNA_2013_12_Tidal_Witham_Haven | ~59.9 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.
