Does S6 flood?

Yes — parts of the S6 district carry real flood risk: 52 of its 132 at-risk postcodes reach the Environment Agency's High likelihood band. The S6 postcode district covers Hillsborough, Southey, Stannington, City, close to Loxley, Sheffield, Grimesthorpe, and surrounding villages in parts of South Yorkshire and Derbyshire.

132 postcodes in the S6 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 52 high, 16 medium, 59 low, 5 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
