Designation is a form of legal protection reserved for key structures or features that are privately owned and maintained and that contribute to the management of flood risk. The aim of designation is to ensure that the owners do not inadvertently alter these structures and potentially increase flood risk to themselves, their neighbours and the wider community. A designation is a legally binding notice served on the owner of the structure or feature. It is also a local land charge meaning that the designation will carry onto successive owners or occupiers of the land.
