Does YO51 9FG flood?

Up to Low likelihood

Properties in YO51 9FG sit in the Environment Agency's 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.

Likelihood band	Annual chance	Properties
High	greater than 3.3%	0
Medium	1% – 3.3%	0
Low	0.1% – 1%	1
Very low	below 0.1%	1

Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.
