Does NN11 flood?

Yes — parts of the NN11 district carry real flood risk: 8 of its 23 at-risk postcodes reach the Environment Agency's High likelihood band. The NN11 postcode district covers Woodford & Weedon, Braunston & Crick, Rural South Northamptonshire, Long Buckby, close to Hinton, Weedon Bec, Dodford, and surrounding villages in parts of West Northamptonshire and Oxfordshire.

23 postcodes in the NN11 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 8 high, 3 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).
