Does NR15 flood?

Yes — parts of the NR15 district carry real flood risk: 6 of its 24 at-risk postcodes reach the Environment Agency's High likelihood band. The NR15 postcode district covers Newton Flotman, Hempnall, Forncett, Brooke, close to Rockland St Mary, Surlingham, and surrounding villages in Norfolk.

24 postcodes in the NR15 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 6 high, 5 medium, 13 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
