Does Bicester flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Bicester
Ordnance Survey places 34 postcodes in Bicester 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 289 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 14 | 74 | 67 |
| Medium | 7 | 93 | 85 |
| Low | 13 | 122 | 101 |
| Very low | 0 | 0 | 0 |
| All bands | 34 | 289 | 253 |
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.
