Each mark is a postcode's centre point as ONS gives it, not a building. Press one to see its postcode and open its page. A dashed outline shows where 5 or more lie within 310 metres of each other. 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 TR20 at risk of flooding?

96 of the 517 postcodes in TR20 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 213 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 96 of 517 postcodes High: 102Medium: 111Low: 186Very low: 113

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.
