What does surface water flood risk mean for buyers?

Rain can overwhelm drainage

Surface water flooding happens when rainfall exceeds what drains and ground can handle. It is not the same mechanism as main river flooding, though both can affect the same property in extreme events.

Maps are guidance, not prophecy

Official mapping helps you understand broad risk. It does not guarantee outcomes in a specific storm.

Insurance conversations

Insurers assess risk with their own questions and models. If you are unsure, speak to an insurance broker. This guide does not give insurance advice.
