Does CH45 flood?

Yes — parts of the CH45 district carry real flood risk: 12 of its 52 at-risk postcodes reach the Environment Agency's High likelihood band. The CH45 postcode district covers Wallasey, New Brighton, Leasowe and Moreton East, close to Moreton, Bootle, Upton (Wirral), and surrounding villages in Liverpool City Region.

52 postcodes in the CH45 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 12 high, 40 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).
