Who are the risk management authorities?

  • The Environment Agency is responsible for managing risk from main rivers, reservoirs, estuaries and the sea.
  • Milton Keynes Council, as Lead Local Flood Authority, is responsible for managing the risk of flooding from surface water, groundwater and ordinary watercourses. Ordinary watercourses are all rivers and streams which are not designated as ‘main rivers’.
  • Milton Keynes Council also carries out flood risk management works on minor watercourses. As Lead Planning Authority we are responsible for controlling development in their area, ensuring that flood risks are effectively managed.
  • Water and sewerage companies are responsible for managing the risks of flooding from drainage systems, including both their surface water only systems and combined sewer systems.
  • Highway Authorities are responsible for providing and managing highway drainage and roadside ditches, and must ensure that road projects do not increase flood risk.
