This letter signals the release of the new Development Advice Maps (DAMs). It also contains important information on Shoreline Management Plans.

The 2015 DAMs replace the earlier DAMs, dated 2013, which are cancelled.

TAN 15 includes a commitment for reviewing the DAMs to allow for new and/or improved flood information to be incorporated. That review process is continuous and the 2015 update benefits from improved and more up to date flood modelling data from Natural Resources Wales.

The letter also provides an update on Shoreline Management Plans.  Coastal local planning authorities should have regard for the Plans in their Local Development Plans and planning decisions.
