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 SG11 at risk of flooding?

73 of the 379 postcodes in SG11 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 115 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 73 of 379 postcodes High: 58Medium: 57Low: 276Very low: 60

High: 3.3% or more a year (1 in 30). Medium: 1% to 3.3% a year. Low: 0.1% to 1% a year. Very low: under 0.1% a year (1 in 1,000). Each band is the chance of flooding in any one year.

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.
