Does L25 flood?

Yes — parts of the L25 district carry real flood risk: 1 of its 16 at-risk postcodes reach the Environment Agency's High likelihood band. The L25 postcode district covers Belle Vale, close to Netherley, Aintree, St Helens, and surrounding villages in Liverpool City Region.

16 postcodes in the L25 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 1 high, 1 medium, 14 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).

No recorded flood extent is mapped near this district's centre.
