Does NW11 flood?

Yes — parts of the NW11 district carry real flood risk: 23 of its 46 at-risk postcodes reach the Environment Agency's High likelihood band. The NW11 postcode district covers Childs Hill, Golders Green, Garden Suburb, Hendon, close to Finchley, Totteridge, Willesden, and surrounding villages in parts of Greater London and Hertfordshire.

46 postcodes in the NW11 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 23 high, 4 medium, 19 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
