Does PE34 4SG flood?

Up to Very low likelihood

Properties in PE34 4SG sit in the Environment Agency's Very low flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
