Does EN3 flood?

Yes — parts of the EN3 district carry real flood risk: 10 of its 195 at-risk postcodes reach the Environment Agency's High likelihood band. The EN3 postcode district covers Enfield Lock, Brimsdown, Ponders End, Carterhatch, close to Enfield Wash, Sewardstone, Waltham Abbey, and surrounding villages in parts of England and Essex.

195 postcodes in the EN3 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 10 high, 6 medium, 75 low, 104 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).
