Does Southam flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Southam
Ordnance Survey places 20 postcodes in Southam 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 92 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 6 | 26 | 24 |
| Medium | 4 | 7 | 5 |
| Low | 10 | 59 | 52 |
| Very low | 0 | 0 | 0 |
| All bands | 20 | 92 | 81 |
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.
