Does North Weald Bassett flood?
What the Environment Agency's rivers-and-sea flood-risk data says about North Weald Bassett
Ordnance Survey places 22 postcodes in North Weald Bassett in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 284 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 3 | 31 | 31 |
| Medium | 1 | 6 | 6 |
| Low | 10 | 115 | 94 |
| Very low | 8 | 132 | 121 |
| All bands | 22 | 284 | 252 |
This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.
