Development Advice Maps (DAM)

The Development Advice Map (DAM) shows areas at risk of flooding for the purposes of land-use planning. The DAM should be used alongside Planning Policy Wales and Technical Advice Note (TAN) 15 to guide new development away from areas at risk of flooding wherever possible. Together, they form a precautionary framework to guide planning decisions. The maps shown here are not designed for small-scale investigation beyond 1:25,000 and should be considered as a trigger for following policy advice in TAN15. The maps are based on Natural Resources Wales's extreme flood outlines (Zone C) and the British Geological Survey 10k Superficial Geology data (Zone B).

From March 2017 Zone C1 and C2 is updated quarterly to align with NRW's extreme flood outline updates. Zone B data was originally published in 2004, and revised in 2017.
