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 now progressing.

The business case is expected to be submitted in autumn 2017, following which the outline design will be progressed with a view to tendering and awarding a construction contract in summer 2018.

As we are at the beginning of the feasibility stage the specific flood reduction measures that will form Phase 2 of the scheme are unknown. We will adopt a catchment-wide approach. 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.

We will be considering a mixture of natural flood management measures and engineered options which could include measures such as creating storage in the upper catchment, building woody debris dams to slow the flow and looking at land use and drainage. Engineered options could include raising and building walls and embankments, flood storage areas and bypass channels.

Options for early interventions and quick wins, or possibly a further phased approach to the scheme will also be considered as part of the feasibility study.

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.
