Does DN17 4AQ flood?

Up to Medium likelihood

Properties in DN17 4AQ sit in the Environment Agency's Medium 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	Of which homes
High	greater than 3.3%	0	0
Medium	1% – 3.3%	4	0
Low	0.1% – 1%	6	2
Very low	below 0.1%	0	0

Over a 25-year mortgage, a property in a medium-likelihood area has a 22–57% chance of flooding at least once.
