Lead Local Flood Authority (LLFA)
The Flood and Water Management Act (FWMA) 2010 introduces a range of new powers, duties and responsibilities and makes Knowsley Council a Lead Local Flood Authority (LLFA). The Flood and Water Management Act 2010 sets out the requirement for LLFAs to manage 'local' flood risk within their area. 'Local' flood risk refers to the flood risk from surface water, groundwater and/or from 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 by the Environment Agency.
What are we doing / our responsibilities?
- We have produced a number of strategies for the purposes of assessing local flood risk, as required by the Flood Risk Regulations 2009
- We are currently preparing our Local Flood Risk Management Strategy which sets out how we plan to manage local flood risk, in accordance with the Flood and Water Management Act 2010
- We have a duty to investigate and record all incidents of ‘significant’ flooding.
- We have a duty to maintain a register of assets; these are physical features that have a significant effect on flooding in their area. The asset register can be viewed in person upon appointment at Huyton Municipal Building by using the contact details below.
- We issue consents for altering, removing or replacing certain structures or features on ordinary watercourses; application details are shown below.
- We are a statutory consultee for all major planning applications and provide a substantive response on all surface water drainage proposals.
- We are working with our partners to promote Sustainable drainage systems (SuDS) as part of new developments and have produced a Sustainable Drainage and Surface Water Management Technical Guidance document for developers.
