Does GU22 9PG flood?

Up to Low likelihood

Properties in GU22 9PG 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.

High	greater than 3.3%	0	0
Medium	1% – 3.3%	0	0
Low	0.1% – 1%	17	15
Very low	below 0.1%	3	2
