The responsibility of riparian owners to maintain watercourses so as not to increase flood risk to others is well established in common law. Obviously, individuals must first know whether they are riparian owners, and their responsibilities, if they are to be expected to discharge them. Risk management authorities also need to be properly enabled and resourced to identify and communicate the right management approaches for riparian assets, and enforce maintenance where necessary. The Government’s review of statutory responsibilities for asset maintenance should include reviewing the powers and resources of risk management authorities to communicate appropriate riparian management options, and effectively enforce responsibilities by riparian owners.
