Does CW1 flood?

The CW1 postcode district covers Crewe East, Haslington, Brereton Rural, Bunbury, close to Wistaston Green, Wheelock, Nantwich, and surrounding villages in Cheshire East.

29 postcodes in the CW1 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 7 high, 4 medium, 18 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
