Does PO15 flood?

Yes — parts of the PO15 district carry real flood risk: 7 of its 23 at-risk postcodes reach the Environment Agency's High likelihood band. The PO15 postcode district covers Avenue, Whiteley and Shedfield, Fareham Park, Southwick and Wickham, close to Titchfield, Wallington, Wickham, and surrounding villages in parts of Hampshire and England.

23 postcodes in the PO15 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 7 high, 5 medium, 11 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
