Is DT4 at risk of flooding?

150 of the 997 postcodes in DT4 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 516 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 150 of 997 postcodes High: 205Medium: 311Low: 341Very low: 747

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.
