Does NR21 flood?

Yes — parts of the NR21 district carry real flood risk: 17 of its 48 at-risk postcodes reach the Environment Agency's High likelihood band. The NR21 postcode district covers Bircham with Rudhams, Walsingham, Lancaster South, Stibbard, close to South Creake, Fakenham, Little Walsingham, and surrounding villages in Norfolk.

48 postcodes in the NR21 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 17 high, 5 medium, 26 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
