Leeds Flood Alleviation Scheme Phase 2

The contract has now been awarded for the feasibility and initial design stage for Phase 2 of the flood alleviation scheme. Work to develop a full business case, which will establish the appropriate standard of protection for Leeds, how this can be achieved, what it will cost and how long it will take to deliver is currently being progressed.

The business case is expected to be submitted in December 2017, following which the outline design will be progressed with a view to tendering and awarding a construction contract in autumn 2018. A catchment wide approach has been adopted to establish options for reducing flood risk upstream of the train station.

This means that although the primary aim of the scheme is to reduce the risk of River Aire flooding in Leeds including areas such as Kirkstall and Stourton (outside of the Phase 1 area) - we will look at the upper catchment to identify opportunities where we can work with others to reduce flood risk along the River Aire beyond the Leeds boundary. View the Leeds FAS extents document (PDF 412KB) for more information.

Initial proposals include measures further upstream including the Kirkstall corridor which was badly hit by the floods as well as Stourton, an industrial area that was badly affected on Boxing Day 2015.

Phase 2 will also look 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.

The range of measures proposed are a mixture of Natural Flood Management and new infrastructure including:

  • Creating new woodland areas by planting hundreds of thousands of tree saplings
  • Where possible, using sites in Leeds to retain flood waters when levels are high. Control gates would be used to fill and then release water from the stores back into river when safe to do so.
  • A new 700-metre long flood defence at Stourton with new walls and surface water interventions similar to those installed at Woodlesford as part of phase one.
  • Removing existing obstructions along the river to help reduce water levels, along with also lowering the riverbed in places to improve its capacity and flow.
  • Improving riverbank protection measures along the river catchment in Craven and Pendle along with enhanced woodland areas and installing debris dams.
  • Constructing raised defences along with landscaping, terracing, embankments and walls, but due to the range of measures the height of any engineered defences will not need to be as high as previously projected.

Advanced Works

A programme of advanced works has also been identified. Flood defence options at Stourton have already been investigated enabling work to commence ahead of the main scheme works. This will include a 700 metre flood wall approximately 0.5m high. Works will include a mixture of new wall, refurbished wall and strengthening of existing wall. Surface water flooding is known to be an issue in the area, as such we’re also looking at how this can be reduced. Once the work is complete the area will benefit from an increased level of protection.

A number of natural flood management (NFM) measures have also been identified as work able to start ahead of the main scheme. Some of these include:

  • A tree planting programme on City of Bradford owned land
  • Creation of woodland area in Kirkstall with tree planting
  • Bank protection measures for water quality at Flashby and Eshton Beck
  • Catchment woodland, debris dams and bank protection


The consultation for Phase 2 of the FAS will start on 21st September and run until 16th November. You can download a copy of the LFAS Consultation Leaflet Information (PDF 4MB). You can also respond and provide comment by downloading a copy of the LFAS Consultation Leaflet Questionnaire (PDF 517KB) (please print double sided to return via the freepost address). The project team will be holding drop in sessions for people to come along and discuss the details of the current proposals. The following events have been arranged:

We are committed to getting this work done as quickly as possible but we need to carry out further investigation and important design work so we can be sure Leeds gets the best scheme possible. We anticipate work to start on site early 2019.

Construction contractors; BMM JV Ltd (a joint venture between BAM Nuttall and Mott McDonald) with support from Arup and Thomas Mackay are delivering the scheme on behalf of Leeds City Council.
