Does M1 flood?

Yes — parts of the M1 district carry real flood risk: 3 of its 64 at-risk postcodes reach the Environment Agency's High likelihood band. The M1 postcode district covers Deansgate, Piccadilly, close to Manchester, Ancouts, Salford, and surrounding villages in Greater Manchester.

64 postcodes in the M1 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 3 high, 20 medium, 41 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
