Does PO5 flood?

Yes — parts of the PO5 district carry real flood risk: 70 of its 155 at-risk postcodes reach the Environment Agency's High likelihood band. The PO5 postcode district covers St Jude, Eastney and Craneswater, St Thomas, close to Gosport, Ryde, St Helens, and surrounding villages in parts of Hampshire and Isle of Wight.

155 postcodes in the PO5 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 70 high, 13 medium, 72 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
