Lead Local Flood Authority


To find out who to report flooding to, and details of our flood plans, see our page, flooding advice.

The Flood and Water Management Act 2010 gives us the role of Lead Local Flood Authority (LLFA) for the county. We have a strategic overview role for local flooding and work closely with other organisations to manage local flood risk in East Sussex. Local flooding is defined as flooding from surface water, groundwater and ordinary watercourses (an ordinary watercourse is any river, stream or channel which is not identified on the Environment Agency Flood Map as a Main River). Flooding from main rivers, the sea and large reservoirs is managed via the website of the Environment Agency - GOV.UK.

What are we doing?

Who we are working with

  • The Environment Agency
  • District and Borough councils
  • Internal Drainage Boards
  • Southern Water
  • The South Downs National Park Authority

See the gov.uk website ‘Managing flood risks – who is responsible' - GOV.UK for more information on specific flood risk management responsibilities.
