Does IG3 flood?

Yes — parts of the IG3 district carry real flood risk: 19 of its 110 at-risk postcodes reach the Environment Agency's High likelihood band. The IG3 postcode district covers Mayfield, Goodmayes, Seven Kings, Newbury, close to Wanstead, Romford, Elm Park, and surrounding villages in parts of England and Essex.

110 postcodes in the IG3 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 19 high, 14 medium, 75 low, 2 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).
