Does WA9 flood?

Yes — parts of the WA9 district carry real flood risk: 11 of its 42 at-risk postcodes reach the Environment Agency's High likelihood band. The WA9 postcode district covers Sutton North West, Bold & Lea Green, Parr, Peasley Cross & Fingerpost, close to St Helens, Haydock, Warrington, and surrounding villages in parts of Warrington and Greater Manchester.

42 postcodes in the WA9 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 11 high, 3 medium, 26 low, 2 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).
