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 SS11 at risk of flooding?

67 of the 476 postcodes in SS11 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 188 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 67 of 476 postcodes High: 171Medium: 17Low: 384Very low: 241

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.
