Does BN2 flood?

Yes — parts of the BN2 district carry real flood risk: 30 of its 30 at-risk postcodes reach the Environment Agency's High likelihood band. The BN2 postcode district covers Whitehawk & Marina, Queen's Park, Kemptown, Hanover & Elm Grove, close to Lewes, Shoreham Beach, Newhaven, and surrounding villages in parts of East Sussex and West Sussex.

30 postcodes in the BN2 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 30 high. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
