Is BN1 at risk of flooding?
None of the 1,578 postcodes in BN1 is on the Environment Agency's list of postcodes with a home or business in an area at risk of flooding from rivers or the sea.
Homes and businesses in an area at risk of flooding from rivers or the sea, as the Environment Agency counts them, added up over the postcodes. It is for the land, not each building, and leaves out surface water, groundwater and sewers. Each postcode page has its own figures and its flood warning areas.
