River Aire natural flood management

The first of 450 trees has been planted on the River Aire, in a bid to reduce flood risk.

As part of a natural flood management scheme, thousands of trees in total will be planted across the upper River Aire, designed to slow water flow and reduce flooding downstream.

Ray Bridge Farm, Eshton Beck, Gargrave is the location of the first pilot site where trees such as Dogwood, Guelder Rose, Downy Birch, Alder, and willow will be planted along with hedgerows of hawthorn, blackthorn and hazel. Yorkshire Wildlife Trust staff and volunteers will be leading the planting of trees at the site.

Use of natural flood management comes as part of the Leeds Flood Alleviation Scheme, led by Leeds City Council in partnership with the Environment Agency, which has a catchment wide approach to flood risk as it enters its second stage.

Using natural processes to reduce flood risk, is known as natural flood management, and is an important part of managing and reducing flood risk in a sustainable way alongside more traditional engineering solutions. The interventions will also create habitat for wildlife and help regenerate rural and urban areas through tourism.

The pilot sites will allow the team to monitor and research the techniques and understand the benefits they give to reducing flood risk. The pilot programme will also be used by the Environment Agency and Leeds City Council to develop a co-design approach to working with landowners, tenants, local authorities and other key partners such as the Aire Rivers Trust and the White Rose Forest.

Leader of Leeds City Council Councillor Judith Blake said: “These new trees are a hugely significant part of our plans to protect Leeds from future flooding like the devastation we saw on Boxing Day 2015.

“It’s great to be working with partner authorities along the River Aire to get the first of the trees planted.

“They are part of what will be a range of natural flood management measures in a catchment wide approach to prevent future catastrophic floods affecting communities along the river.”

Adrian Gill, Area Flood Risk Manager at the Environment Agency said: “I’m really pleased to launch this pilot programme in partnership with Leeds City Council. Using natural techniques to minimise flood risk while creating new habitats and increasing woodland cover across the Aire catchment will help realise the ambitions set out in the Defra’s 25 year environment plan.

“While we can never truly eliminate the threat of flooding, working together across local authority boundaries to develop and deliver this programme will help us to create better, more effective solutions to a catchment-wide challenge.”

Phase I of the scheme was opened in October last year, serving the city centre, Holbeck and Woodlesford. Phase II identifies measures further upstream, looking at areas beyond the city boundary to further reduce the possibility of the river flooding in Leeds, as well as additional measures to offer protection for the South Bank area of the city centre which is a key future economic driver for Leeds.

Phase II has a strong focus on natural flood management, with proposals to create new woodland areas more than doubling the canopy coverage in the River Aire catchment. It also proposes water storage areas to be created and developed, operated by control gates system meaning water can be held and then released back into the river when safe to do so. A third element would be the removal of existing obstructions along the river to help reduce water levels, along with lowering the riverbed in places to improve its capacity and flow.
