Sussex Local Flood Risk Management Strategy

Following the significant floods in 2007, one of the direct actions from the Pitt Review  was local authorities were given new powers to help manage local flood risk in a more coordinated way by the Government.

The Flood Water Management Act 2010 requires county councils to lead the coordination of flood risk management for surface water, groundwater and smaller watercourses in their area. East Sussex council has published their own Local Flood Risk Management Strategy, which sets out how they plan on managing local flood risks.

Sussex has two councils, East and West, who are working with organisations to manage local flood risks in Sussex. 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) are defined as ‘Local Flooding’. The Environment Agency deals with flooding from the sea, main rivers and reservoirs.

East Sussex County Council.

Has produced a Preliminary Flood Risk Assessment to assess local flood risk across the county, as required by the Flood Risk Regulations 2009. In addition, they have published a Local Flood Risk Management Strategy which sets out how they plan to manage local flood risk, in accordance with the Flood and Water Management Act 2010. They are currently undertaking a number of Surface Water Management Plans to identify specific areas at risk of local flooding and what actions could be taken to reduce the risk.

They are also working with third parties to develop Sustainable drainage systems (SuDS) as part of new management.

Flooding from watercourses, other than main rivers

Watercourses, other than main rivers, are the responsibility of riparian owners. You are a riparian owner if your property or land is on, or very near, a watercourse. Riparian owners have a duty to keep the watercourse clear of any obstruction to flow. The Council can serve legal notices on riparian owners to deal with obstructions.

Private drains

Private drains are the responsibility of the homeowner/occupier. Your local water company or drainage contractors will fix the damage for a fee.
