Guidance on the climate change allowances to be used in flood assessments.
National planning policy requires proposals for development in areas of high flood risk to be accompanied by an assessment of flooding consequences (FCA).
This has to take into account the effects of climate change. The Welsh government has published guidance on the climate change allowances that should be used in FCAs submitted in support of planning applications from 1 December 2016.
It says the allowances have been developed using the latest information on climate change projections and different scenarios of carbon dioxide emissions to the atmosphere.
