Abstract

The Areas Benefitting from Flood Defences show areas in Wales that benefit from flood defences that protect against flooding from Rivers and the Sea. The areas shown benefit from different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales (FRAW) map. For specific information on the Standard of Protection afforded by flood defences refer to Flood Defences with Standardised Attributes.

Quality and validity

Lineage

The outer boundary for the Areas Benefitting from Flood Defences is fixed to the Low risk flood extent for flooding from Rivers or the Sea (i.e. the area with a 0.1%, or 1 in 1,000, chance of flooding in any year). The data is not property specific and shows the benefit for a general area. This information is different to the previous Flood Map: Areas Benefitting from Flood Defences which only showed the benefit provided in the event of a river flood with a 1% (1 in 100) chance of happening each year, or a flood from the sea with a 0.5% (1 in 200) chance of happening each year. Not all flood defences and areas that benefit from a flood defence are shown.These will gradually be added as information becomes available.
