Does OL5 flood?

Yes — parts of the OL5 district carry real flood risk: 14 of its 48 at-risk postcodes reach the Environment Agency's High likelihood band. The OL5 postcode district covers Mossley, Stalybridge North, close to Greenfield, Delph, Hollingworth, and surrounding villages in parts of Greater Manchester and Derbyshire.

48 postcodes in the OL5 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 14 high, 18 medium, 16 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
