Does PO2 flood?

Yes — parts of the PO2 district carry real flood risk: 13 of its 99 at-risk postcodes reach the Environment Agency's High likelihood band. The PO2 postcode district covers Hilsea, Nelson, Charles Dickens, close to Gosport, Havant, Wallington, and surrounding villages in parts of Hampshire and Isle of Wight.

99 postcodes in the PO2 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 13 high, 3 medium, 76 low, 7 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).
