Up to High likelihood
Properties in GL13 9PY 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% | 1 | 1 |
| Medium | 1% – 3.3% | 0 | 0 |
| Low | 0.1% – 1% | 3 | 3 |
| 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 18 m above sea level and falls 20 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south, 2.8 m higher.
Because properties in the high likelihood band; 3 recorded floods nearby; 387 official warnings since 2006.
