The aim of the Irwell Vale, Strongstry and Chatterton FRMS is to reduce the flood risk within these 3 communities. The communities are located within Rossendale, Lancashire and are hydraulically linked by the River Irwell which is the primary source of fluvial flooding. As the valley is steep sided, the flood events tend to be extremely flashy meaning the communities do not get much warning before a flood event.
There is a long history of flooding with the most recent event occurring during Storm Ciara in February 2020. The communities were also impacted in 2008, 2012 (twice), 2015 and 2017.
