Does CH64 flood?

Yes — parts of the CH64 district carry real flood risk: 3 of its 24 at-risk postcodes reach the Environment Agency's High likelihood band. The CH64 postcode district covers Parkgate, Little Neston, Willaston & Thornton, Heswall, close to Ellesmere Port, Upton (Wirral), Chester, and surrounding villages in parts of Cheshire West and Chester and Liverpool City Region.

24 postcodes in the CH64 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 3 high, 4 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).
