Helping you understand Welsh law

Flood, coastal protection and drainage

The law on flood risk management is generally to be found in the Flood and Water Management Act 2010, the functions in which are largely devolved to the Welsh Ministers. 

The 2010 Act provides for a national flood and coastal erosion risk management strategy in relation to Wales, and for local flood risk management strategies.

The 2010 Act also provides for regional flood and coastal committees.  The Welsh Government introduced the Environment (Wales) Bill into the National Assembly for Wales in May 2015. The Bill proposes to replace these committees in Wales with a new body (the Flood and Coastal Erosion Committee).

The Flood Risk Regulations 2009 implement the requirements of the European Floods Directive .The Directive aims to provide a consistent approach to managing flood risk.

The law in relation to coastal erosion is generally to be found in the Coast Protection Act 1949, functions under which have generally been transferred to the Welsh Ministers.

The law in relation to land drainage is generally to be found in the Land Drainage Act 1991. This area of law includes such matters as duties on landowners to drain land and protect land from flooding, and the functions of Internal Drainage Boards, Natural Resources Wales and the Welsh Ministers.
