Does SG5 flood?

Yes — parts of the SG5 district carry real flood risk: 18 of its 55 at-risk postcodes reach the Environment Agency's High likelihood band. The SG5 postcode district covers Stotfold, Hitchin Bearton, Hitchin Priory, Cadwell, close to Arlesey, Shefford, Biggleswade, and surrounding villages in parts of Central Bedfordshire and Hertfordshire.

55 postcodes in the SG5 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 18 high, 10 medium, 27 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
