Does CH3 flood?

Yes — parts of the CH3 district carry real flood risk: 50 of its 72 at-risk postcodes reach the Environment Agency's High likelihood band. The CH3 postcode district covers Farndon, Tattenhall, Sandstone, close to Abbot's Mead, Chester, Chester, Bridge Trafford, and surrounding villages in Cheshire West and Chester.

72 postcodes in the CH3 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 50 high, 4 medium, 14 low, 4 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).
