Does CA4 9PH flood?

Up to High likelihood

Properties in CA4 9PH sit in the Environment Agency's High 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%	1
Medium	1% – 3.3%	0
Low	0.1% – 1%	2
Very low	below 0.1%	0

Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
