Does RG45 flood?

Yes — parts of the RG45 district carry real flood risk: 11 of its 20 at-risk postcodes reach the Environment Agency's High likelihood band. The RG45 postcode district covers Crowthorne, close to Wokingham, Blackwater, Eversley, and surrounding villages in parts of Wokingham and Hampshire.

20 postcodes in the RG45 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 11 high, 6 medium, 3 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
