Does Bexley flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Bexley
Ordnance Survey places 32 postcodes in Bexley 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 359 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 8 | 148 | 125 |
| Medium | 5 | 16 | 11 |
| Low | 19 | 149 | 120 |
| Very low | 0 | 46 | 41 |
| All bands | 32 | 359 | 297 |
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.
