Is NN4 at risk of flooding?

93 of the 980 postcodes in NN4 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 13 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 93 of 980 postcodes High: 3Medium: 10Low: 974Very low: 421

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.
