Does NR8 flood?

Yes — parts of the NR8 district carry real flood risk: 8 of its 19 at-risk postcodes reach the Environment Agency's High likelihood band. The NR8 postcode district covers Old Costessey, Drayton South, Great Witchingham, Taverham South and surrounding villages in Norfolk.

19 postcodes in the NR8 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 8 high, 5 medium, 6 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
