Does IP31 flood?

Yes — parts of the IP31 district carry real flood risk: 18 of its 46 at-risk postcodes reach the Environment Agency's High likelihood band. The IP31 postcode district covers Walsham-le-Willows, Thurston, Pakenham & Troston, Bardwell, close to Fornham St Martin, Knettishall, Rattlesden, and surrounding villages in parts of Suffolk and Norfolk.

46 postcodes in the IP31 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 18 high, 11 medium, 17 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).

No official flood warning or alert is on record for areas near the centre of this district since 2006.
