Cambridgeshire County Council is a Lead Local Flood Authority (under the Flood and Water Management Act 2010)  with the responsibility for managing the following types of flooding:

  • surface water flooding - includes flooding from rainfall run off from surfaces such as roads, roofs and patios. For more information refer to the Environment Agency's interactive surface water map.
  • ordinary watercourses - includes flooding from drains and ditches, but excludes main rivers that are managed by the Environment Agency. A map of the main rivers is available on the Environment Agency's website.
  • groundwater flooding - includes flooding caused by heavy and sustained levels of rainfall capable of increasing the groundwater table

The main responsibilities as a flood authority include:

  • investigating and reporting on significant flood events in the county
  • establishing and maintaining a register for all significant flood risk assets in the county
  • producing a local flood risk management strategy to manage surface water, ordinary watercourses and groundwater flooding in partnership with other risk management authorities in the county.
  • ensuring that new developments are designed and built in a sustainable manner which does not increase flood risk, and to reduce flood risk whenever possible
  • consenting new work which affects the flow of ordinary watercourses, if you are unsure what construction work requires consent or to apply for consent please go to watercourse management.
  • the power to request information relating to flooding from any organisation or individual
  • the power to designate significant flood risk assets or features to ensure they are managed properly and continue to protect people and property from flooding
  • the power to enforce remedial works on unapproved construction work within ordinary watercourses or those not undertaking their landowner (riparian) responsibilities

Flood risk asset management

The Flood and Water Management Act (FWMA) 2010 gives the County Council the duty to maintain a register of structures or features which (in the opinion of the council) are likely to have a significant effect on flood risk in its area.

Register of flood risk assets 

The Register of Flood Risk Assets is for information purposes in accordance with section 21 of the Flood and Water Management Act 2010. The data published has been collected from different sources and therefore may contain errors. However, we are constantly improving data quality. Cambridgeshire County Council accepts no liability for any issues connected with the use of this data.

Flood risk management partnership

The Cambridgeshire Flood Risk Management Partnership (CFRMP) was established to bring together key stakeholders in flood risk management to meet the Council's new statutory duties. The partnership provides a coordinated and collaborative approach to flood risk management across the county.

Partners include the County Council, Environment Agency, Anglian Water, district councils, Middle Level Commissioners and Internal Drainage Boards.

The partnership was formed to deliver new duties arising from:

Flood risk management strategy

Cambridgeshire County Council (under the Flood and Water Management Act 2010) has a duty to produce a Flood Risk Management Strategy in partnership with key stakeholders involved in flood risk management.

The strategy's main focus is on flooding from surface water, groundwater and ordinary watercourses, such as streams and ditches. Although the risk of flooding from rivers remains the responsibility of the Environment Agency, this strategy looks at the interaction between all forms of flood risk.

The final version of Cambridgeshire's Local Flood Risk Management Strategy has been approved by Cabinet and endorsed by full Council.
