Quick answers

Questions people ask

Which town in Merseyside has the lowest flood risk?

Aintree ranks first on flood risk among 25 towns, with an A: no homes at high or medium flood risk. Billinge and Bootle follow.

How are these towns ranked?

In England and Wales the Hazard risk Grade measures flood risk: the share of the town’s homes at high or medium risk of flooding from rivers or the sea (Environment Agency, Natural Resources Wales). The letter and rank are the same as on each town’s page. How grades work.

Why isn’t my town on this list?

Garrison towns and university campuses aren’t ranked, and towns without the figures this grade needs are counted above. The list covers Merseyside’s towns of 2,500+ with the figure. Smaller places show it on their own pages; every town in Merseyside is on the county page.
