Does RG40 flood?

Yes — parts of the RG40 district carry real flood risk: 14 of its 27 at-risk postcodes reach the Environment Agency's High likelihood band. The RG40 postcode district covers Barkham & Arborfield, Norreys, Wescott, close to Wokingham, Sindlesham, Eversley, and surrounding villages in parts of Wokingham and Hampshire.

27 postcodes in the RG40 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 14 high, 7 medium, 6 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
