Lead local flood authority

Power to do works

Sutton Council have new powers through the Flood and Water Management Act 2010.

We are empowered to do work to manage the risk of flooding from surface water, groundwater and ordinary watercourses (typically ditches, and small streams). Any work that the council wish to do must be in line with the Local Flood Risk Management Strategy.

The types of work that might use this power include:

  • Building or altering structures
  • Maintaining or restoring natural processes
  • Changing water levels (higher and lower)
  • Doing works on a river like diverting the banks and removing litter (like shopping trolleys)

The works are allowed to increase the amount of water below the ground or potential for flooding, as long as the benefits of the work outweigh the harmful consequences.

Work must meet the following four conditions:

  • The work is in the interest of either nature conservation, the preservation of cultural heritage or people's enjoyment of the environment and/or cultural heritage
  • The benefits of the scheme outweigh the harmful consequences to Human Health, the Environment, Infrastructure and the social and economic welfare of individuals and communities
  • The Environment Agency are consulted and consent to the work
  • Parties who are directly affected are consulted
