Flood Map for Planning (FMfP) TAN15 Defended Zones
The Flood Map for Planning (FMfP) includes climate change information to show how this will affect flood risk extents for rivers, the sea and surface water and small watercourses over the next century. It shows the potential extent of flooding assuming no defences are in place. It also indicates areas at risk from coastal erosion, areas that have flooded in the past and key information on the location of flood defence infrastructure.
The FMfP can be considered as the best available information on flood risk and will replace the Development Advice Map for planning purposes when the Welsh Government implements the revised TAN15. Although it currently has no official status for planning purposes it is a useful data source when considering flood risks.
The coming into force of the new TAN 15 and the Flood Map for Planning has been suspended due to a further consultation on the TAN.
Technical advice note (TAN) 15: development, flooding and coastal erosion - https://www.gov.wales/technical-advice-note-tan-15-development-flooding-and-coastal-erosion
The FMfP introduces a new layer called the TAN15 Defended Zone. This shows areas that benefit from risk management authority owned flood defence infrastructure, that have a minimum, Present Day level of protection of:
• 1% (1 in 100) annual event probability (AEP) for rivers, or
• 0.5% (1 in 200) annual event probability (AEP) for the sea.
Flood defences built after 1 January 2016 must also include design freeboard and an allowance for climate change.
