Images of a £112M Leeds flood defence project have been released.
Phase two of the Leeds Flood Alleviation Scheme will include flood defence walls along the River Aire, water storage sites using innovative moveable weir technology and Natural Flood Management methods.
Sketches, produced by the city council, environment agency and BMM JV - a joint venture between Bam Nuttall and Mott MacDonald - have been released ahead of the submission of a planning application later this summer, with work expected to begin next year.
The second phase aims to reduce flood risk upstream of the city centre including the Kirkstall corridor which was badly hit by Storm Eva at Christmas 2015.
“We are pleased to bring forward these proposals, which are the result of extensive work carried out to identify the level of protection we need, as requested by the government following the devastation caused by the impact of Storm Eva,” said Leeds City Council leader Judith Blake.
“Working with the Environment Agency and partners, what we are putting forward is a modern catchment-wide approach to flood prevention utilising a range of measures including a strong focus on tree planting and natural measures to provide the reassurance our communities and businesses need and deserve.
“The images are early indicative sketches at this stage but give a flavour as to how it could look. This scheme being supported and approved by the government as quickly as possible is essential so we can get on and do the work we need to get done.”
The movable weir technology was used in the UK for the first time as part of the £50M first stage of the Leeds scheme and can be raised or lowered to control the flow of water depending on river level.
The weirs are controlled by deflating and inflating ‘bladders’ fabricated from a bullet proof neoprene material under each gate, which act like giant air-filled pillows. This raises or lowers a gate to control water levels, preventing flood water from reaching the city.
