The preferred ‘slowing the flow’ approach is to revise how Yorkshire Water’s existing compensation reservoirs are operated to store floodwater upstream of the city, however this approach may prove undeliverable. The City Council and the Environment Agency recognise that the Roscoe FSA option would be a challenging scheme to design in a manner that satisfies the concerns of affected parties, however this FSA is the most cost effective ‘slowing the flow’ alternative to the preferred approach.
