Does NR20 flood?

Yes — parts of the NR20 district carry real flood risk: 20 of its 51 at-risk postcodes reach the Environment Agency's High likelihood band. The NR20 postcode district covers Upper Wensum, Lincoln, Eynesford, Mattishall, close to Swanton Morley, Clint Green, Podmore, and surrounding villages in Norfolk.

51 postcodes in the NR20 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 20 high, 8 medium, 23 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
