Does RH13 flood?

Yes — parts of the RH13 district carry real flood risk: 11 of its 23 at-risk postcodes reach the Environment Agency's High likelihood band. The RH13 postcode district covers Cowfold, Shermanbury & West Grinstead, Southwater South & Shipley, Itchingfield, Slinfold & Warnham, Nuthurst & Lower Beeding, close to Horsham, Tanbridge, Wineham, and surrounding villages in West Sussex.

23 postcodes in the RH13 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 11 high, 3 medium, 9 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
