Up to Low likelihood
Properties in WN3 5BU sit in the Environment Agency's Low flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
| Likelihood band | Annual chance | Properties | Of which homes |
|---|---|---|---|
| High | greater than 3.3% | 0 | 0 |
| Medium | 1% – 3.3% | 0 | 0 |
| Low | 0.1% – 1% | 6 | 3 |
| Very low | below 0.1% | 12 | 12 |
Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.
The ground here sits at about 28 m above sea level and falls 11 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the east-north-east, 7.4 m higher.
Because properties in the low likelihood band; 6 recorded floods nearby; 74 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around WN3 5BU. 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.
