Does EC4Y flood?

Only lower-likelihood flood risk is recorded in EC4Y: none of its 30 listed postcodes goes beyond the Low band. The EC4Y postcode district covers Farringdon Without, Castle Baynard, St James's, close to Westminster, Tower Pier, Stoke Newington, and surrounding villages in parts of England and Greater London.

30 postcodes in the EC4Y district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 30 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).
