Flood risk management

There have been a number of severe flood events experienced across the UK in recent years, which are a reminder that flooding can have devastating consequences.

Vehicles going through flooding

Climate change is predicted to result in more storm events and even greater levels of rainfall. The probability of flooding is therefore increasing. The impacts from flood events are also likely to become more severe if lessons are not learned from flood events. 

Following the floods in 2007, Sir Michael Pitt carried out an extensive independent review. This looked at the causes as well as the management of flooding matters before during and after the event. The Pitt review found a lack of clarity in which agencies had responsibility for flood management, and identified improvements that could be made in a series of recommendations to the Government. 

Flood Risk Regulations 2009

The Flood Risk Regulations 2009 implement the requirements of the European Floods Directive. The aim of the directive was to provide a consistent  approach to managing flood risk across Europe. It establishes four stages of activity within a six year flood risk management cycle.

  • Stage 1: Undertaking a Preliminary Flood Risk Assessment (PFRA)
  • Stage 2: Identifying Flood Risk Areas. 
  • Stage 3: Preparing flood hazard and risk maps. Produced by the Environment Agency.
  • Stage 4: Preparing flood risk management plans. Produced by the Environment Agency. The Thames River Basin Flood Risk Management Plan is available on the Environment Agency website.

Flood and Water Management Act 2010

In July 2010, the Flood and Water Management Act set out the new management structure for dealing with flooding. The Act ensured the Environment Agency maintained the lead for river, tidal and coastal flooding. Importantly, it also provided much greater clarity regarding the lead for management of other sources of flooding such as surface water, groundwater and flooding  from ordinary watercourses. 

The lead for managing these local types of flooding now falls to Lead Local Flood Authorities, namely Local Authorities. The London Borough of Hillingdon has been designated a Lead Local Flood Authority and consequently has a new range of responsibilities relating to the following:

  • Recording information from flood events. A number of flood risk investigations have been undertaken and published by Hillingdon.
  • Registering assets (These could be rivers or a pumping stations) that have been identified as having a role to play in flood management and not owned by Hillingdon.
  • Flood risk mapping and information gathering. 
  • Emergency planning, be prepared, find out ways to see if you are at risk, and what can be done to reduce the impact on your family.
  • Sustainable drainage is now a material consideration for all major planning applications

Flood risk management portfolio of documents

The London Borough of Hillingdon is aiming to develop a greater understanding of  flood risk amongst residents and property owners, a key requirement of the Flood and Water Management Act and the Flood Risk Regulations. Flood risk can best be demonstrated through flood modelling and mapping.

Ultimately, the council  will have a flood risk management portfolio, which will include a series of maps and plans, for all types of potential flooding, to highlight the areas of highest risk,  action plans for reducing flood risk and a clear emergency planning process. At present, this portfolio comprises the following documents:​

This page will provide updates as the relevant parts of the act are implemented and more information becomes available.
