Does Spalding flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Spalding
Ordnance Survey places 743 postcodes in Spalding 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 15,847 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 6 | 21 | 14 |
| Medium | 668 | 13,109 | 11,847 |
| Low | 33 | 852 | 720 |
| Very low | 36 | 1,865 | 1,517 |
| All bands | 743 | 15,847 | 14,098 |
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.
