Is DN34 at risk of flooding?

168 of the 470 postcodes in DN34 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 none of the homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 168 of 470 postcodes Low: 521Very low: 2,310

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.
