Tell us if you want any of the documents on this page in an alternative format.
This letter and accompanying guidance note set out allowances for climate change for use in Flood Consequences Assessments.

Development should not take place where the risk of flooding is unacceptable now or in the future.

The risk of flooding is expected to increase as a result of climate change and it is important for consideration to be given to this increased risk when considering planning applications and preparing and reviewing Local Development Plans.  

Local planning authorities, applicants and their consultants are expected to use these climate projections from 1 December 2016.
