Knostrop Quay (KQ) Arm /Old Mill Lane Basin Adjacent to the H2010 Development
Knostrop Quay enhancement options continue to be developed. Further discussion with stakeholders is necessary to fully evaluate the options in this area before we will be in a position to consult members of the public on the proposals. There will be further consultation with the residents of the H2010 development on the draft details before the plans are finalised.
Flood risk is increasing throughout the UK and in recent years Leeds city centre has come close to flooding several times.
There are currently no formal flood defences along the River Aire and in order to ensure and support further growth and regeneration of the Leeds economy, a flood defence scheme is needed to help protect the homes, businesses and transportation networks of Leeds.
Scheme Proposals and Project Details
Leeds City Council, working alongside the Environment Agency, the Canal and River Trust and other partners, are developing proposals to protect Leeds city centre (between Leeds station and Knostrop weir) from a flood event likely to happen once every 75 years. The likelihood of a 1 in 75 flood event occurring in any given year is 1.3%. (See ‘Flood Alleviation Scheme FAQ’ in the Documents section of this page for more details).
The proposed 1 in 75 flood protection scheme will:
- Remove the existing weirs at Crown Point in the city centre and at Knostrop Cut and install moveable weirs that can be lowered when the river is high, causing the water level to drop. An animation showing the typical operation scenario of the Crown Point weir can be seen, via youtube, by using the ‘Crown Point Weir’ link under the external links heading;
- Construct landscape defences such as low level embankments, terracing and riverside walls; at low points along the riverbank;
- Remove Knostrop Cut to merge the Canal and River Aire which will create additional flood water storage and help to lower water levels in flood conditions;
- Provide flood defences along a length of Holbeck located on Water Lane;
- Provide defences to Woodlesford in the form of low level embankments to achieve a protection against a flood event that is likely to occur every 200 years.
Planning permission for the movable weirs has been granted. Details for this can be viewed by using the ‘Planning Permission Weirs on the River Aire’ link under the External links heading.
Funding and Programme
The scheme is estimated to cost in the region of £50.5m and is being funded through a partnership supported by Defra and the Treasury, Leeds City Council and local businesses. This work is due to start during 2013/2014 and be completed in 2016.
