Guidance that outlines ways in which the planning system can
support communities and people to avoid being affected by
flooding, and to develop more resilience where it cannot be
avoided, has been published.
Following public consultation, the revised Technical Advice Note
15 (TAN) supports planners to assess flood risks from rivers, the
sea and surface water, as well as the risk of coastal erosion.
It also provides advice on adapting to and living with flood
risk.
Publishing the TAN, the Cabinet Secretary for Economy, Energy and
Planning, warned the frequency and
severity of flooding is increasing and is expected to rise
further as a result of climate change:
“Recent storms have brought into sharp focus the devastating
effect flooding can have on the lives and businesses of people
across Wales. It can happen at any time of the year, and often
without significant warning resulting in serious consequences.
“That's why it's essential the planning system fully recognises
the likelihood and potential impacts of future flooding events.
“The TAN takes a risk-based approach using the Flood Map for
Planning to balance the likelihood of flooding events against the
vulnerability of development.
“In essence, the higher the likelihood of flooding and the
greater the vulnerability of development, the more restrictive
the policy becomes.”
The new guidance is effective immediately while a transitional
period is in place for applications already in progress.
