Does L10 flood?

Yes — parts of the L10 district carry real flood risk: 3 of its 5 at-risk postcodes reach the Environment Agency's High likelihood band. The L10 postcode district covers Molyneux, Fazakerley East, Park, close to Aintree, Sefton, Bootle, and surrounding villages in parts of Liverpool City Region and Lancashire.

5 postcodes in the L10 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 3 high, 1 medium, 1 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
