Does SO30 flood?

Yes — parts of the SO30 district carry real flood risk: 19 of its 54 at-risk postcodes reach the Environment Agency's High likelihood band. The SO30 postcode district covers West End North, Botley, close to Hedge End, Curdridge, Swaythling, and surrounding villages in parts of Hampshire and England.

54 postcodes in the SO30 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 19 high, 6 medium, 16 low, 13 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
