Does Grove flood?

What the Environment Agency's rivers-and-sea flood-risk data says about Grove

Ordnance Survey places 29 postcodes in Grove 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 212 properties in the EA dataset's likelihood bands.

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.
