Up to Low likelihood
Properties in BB10 4DB 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% | 15 | 15 |
| Very low | below 0.1% | 0 | 0 |
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 118 m above sea level and falls 50 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-east, 47.3 m higher.
Because properties in the low likelihood band; 2 recorded floods nearby; 106 official warnings since 2006.
