Does CO6 flood?

Yes — parts of the CO6 district carry real flood risk: 42 of its 63 at-risk postcodes reach the Environment Agency's High likelihood band. The CO6 postcode district covers Coggeshall, The Colnes, Lexden and Braiswick, close to Bures, Colne Engaine, Beacon End, and surrounding villages in parts of Essex and Suffolk.

63 postcodes in the CO6 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 42 high, 9 medium, 12 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
