Leigh, Wigan
Up to Low likelihood
Properties in WN7 2GJ 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% | 9 | 9 |
| 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 22 m above sea level and falls 19 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south-west, 2.5 m higher.
Because properties in the low likelihood band; 1 recorded flood nearby; 85 official warnings since 2006.
