Does BN23 flood?

Yes — parts of the BN23 district carry real flood risk: 20 of its 430 at-risk postcodes reach the Environment Agency's High likelihood band. The BN23 postcode district covers Sovereign, St Anthony's, Langney, Hampden Park, close to Eastbourne Harbour, Pevensey Bay, Hellingly, and surrounding villages in East Sussex.

430 postcodes in the BN23 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 20 high, 2 medium, 7 low, 401 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).
