Does SO24 flood?

Yes — parts of the SO24 district carry real flood risk: 23 of its 31 at-risk postcodes reach the Environment Agency's High likelihood band. The SO24 postcode district covers Alresford and Itchen Valley, Upper Meon Valley, Oakley & The Candovers, close to New Alresford, Itchen Stoke, Easton, and surrounding villages in Hampshire.

31 postcodes in the SO24 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 23 high, 1 medium, 7 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
