Is RH1 at risk of flooding?

122 of the 1,245 postcodes in RH1 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 559 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 122 of 1,245 postcodes High: 381Medium: 178Low: 889Very low: 15

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.
