Does CO8 flood?

Yes — parts of the CO8 district carry real flood risk: 15 of its 23 at-risk postcodes reach the Environment Agency's High likelihood band. The CO8 postcode district covers Stour Valley South, close to Bures, Lamarsh, Colne Engaine, and surrounding villages in parts of Suffolk and Essex.

23 postcodes in the CO8 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 15 high, 3 medium, 5 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
