Does Whitstable flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Whitstable
Ordnance Survey places 289 postcodes in Whitstable 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 5,759 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 56 | 520 | 317 |
| Medium | 30 | 423 | 334 |
| Low | 96 | 2,242 | 1,323 |
| Very low | 107 | 2,574 | 2,100 |
| All bands | 289 | 5,759 | 4,074 |
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.
