Up to High likelihood
Properties in DN35 7UL sit in the Environment Agency's High 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% | 22 | 21 |
| Medium | 1% – 3.3% | 5 | 5 |
| Low | 0.1% – 1% | 3 | 2 |
| Very low | below 0.1% | 0 | 0 |
Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
The ground here sits at about 3 m above sea level and falls 4 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south, 1.7 m higher.
Because properties in the high likelihood band; 5 recorded floods nearby; 52 official warnings since 2006.
The map above shows the real EA rivers & sea likelihood cells around DN35 7UL. 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.
