Welsh Government to release updated TAN15 Guidance


The Welsh Government are expected to release updated TAN15 guidance and associated supporting flood mapping by the end of this month. TAN15 is the guidance by which all development in Wales is assessed with regards to flood risk from rivers and drainage. Before developing in an area at risk of flooding, it must be demonstrated that the flood risks and consequences can be acceptably managed in line with national planning policy.

The update to the 2004 guidance has been anticipated for approximately two years and it is expected that there will be significant changes to law and how flood risk is assessed for planning. Any planning applications made after December 1st 2021, will need to fully comply with the new guidance. More information about the process can be found on the Natural Resources Wales website.
