It is not a boundary, and no boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode.

Is BB3 at risk of flooding?

98 of the 931 postcodes in BB3 have a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 757 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 98 of 931 postcodes High: 429Medium: 328Low: 504

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.
