Drainage, Coastal Erosion and Flood Prevention

Sefton Council is a Lead Local Flood Authority (LLFA) and under the Flood and Water Management Act 2010, we are required to produce a flood risk management strategy. The Act requires each Lead Local Flood Authority in England and Wales to set out a comprehensive view of how it will manage flood risk in its area. Our strategy also satisfies the requirement under the Flood Risk Regulations 2009 for a Flood Risk Management Plan.

Flood risk and coastal erosion are serious issues for Sefton, the Community Risk Register places flooding, in particular, as one of our most significant risks. We take these risks seriously, having suffered severe surface water flooding a number of times since 2009. In addition, parts of Sefton are influenced by shallow groundwater and the flood risk from the River Alt and other main rivers. These factors plus our coastal geomorphology make Sefton sensitive to the effects of climate change. Some flood risk can be alleviated by improving the design and maintenance of our drainage assets, coastal defences and the delivery of new infrastructure projects, others by increasing public awareness of the risks and working with communities.

The purpose of this Strategy is to help individuals, communities, businesses and authorities to better understand and manage flood risk in Sefton. Our Strategy is complimented by a supporting Service Delivery Plan and an Investment Plan. Our Service Delivery Plan provides details of the activities we undertake and the Investment Plan sets out how our activities are resourced and identifies areas where we will need to seek funding.

It is important to remember that flooding and coastal erosion are both natural processes. They occur when specific environmental factors or a combination of factors happen. They only become a problem when they have the potential to adversely impact on people, property, infrastructure, our environment and our economy.

March 2021 - Flood Risk Joint Statement of Intent

Sefton Council, the Environment Agency and United Utilities have signed a joint statement of intent to reassure Maghull communities that they are continuing to work together to explore solutions to reduce the risk of flooding.

The statement strengthens the collaborative approach already undertaken to manage and reduce flood risk, further prompted by weather events in January. A major incident was declared due to significant rainfall brought by Storm Christoph on Wednesday 20th January 2021 which also saw the Environment Agency issue two Severe Flood Warnings in Maghull, covering 439 properties within the flood warning area.

The predicted flooding did not happen as expected but the incident highlighted the need for all three organisations to come together to find deliverable improvements that make a significant difference for the community.

All three organisations have sought to manage the risks through a range of means to date including routine maintenance, capital investments, improvements to warning and informing residents as well as planning control. Alongside the statement of intent, a new flood risk working group will also be established with representation from all three agencies.
