Does BN6 flood?

Yes — parts of the BN6 district carry real flood risk: 18 of its 37 at-risk postcodes reach the Environment Agency's High likelihood band. The BN6 postcode district covers Hassocks, Downland Villages, Plumpton, Streat, East Chiltington & St John, Hurstpierpoint, close to Wineham, Lindfield, Scayne's Hill, and surrounding villages in parts of West Sussex and East Sussex.

37 postcodes in the BN6 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 18 high, 6 medium, 13 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
