With the completion of Phase 1 of the Leeds Flood Alleviation Scheme, this has brought confidence back to 3000 homes and 500 businesses in the city centre that were affected by Storm Eva in 2015 providing a one-in-75 year level of protection against flooding. The £50 million project was undertaken as a joint venture between BAM Nuttall & Mott MacDonald based on a design by ARUP for Leeds City Council. ARUP’s engineering teams devised a scheme that removed 2 main navigation weirs at Knostrop & Crown Point and replaced them with innovative mechanical moving weirs which can be lowered which river levels raise to reduce flooding levels.
At Knostrop Cut, a whole island was removed and the canal and river merged resulting in a navigable channel with a greater water holding capacity.
Low level locations long the city centre including embankments, terracing and walls were improved to provide greater protection against flooding.
