Located in a steep-sided valley at the confluence of three watercourses, Hebden Bridge has a long history of regular flooding, with risk of fluvial, canal, pluvial and surface water flooding. The flooding on Boxing Day 2015 was estimated to have impacted 551 properties.
Hebden Bridge Flood Alleviation Scheme (FAS) has been developed by the multi-agency Calderdale Flood Partnership, made up of the Environment Agency, Calderdale Council, Yorkshire Water, the Canal & River Trust and Network Rail. The scheme looks to address all sources of flooding in Hebden Bridge through a mixture of fluvial defence improvements, property level resilience and a surface water drainage scheme.
We are developing an integrated hydraulic model that considers all sources and contributions to flooding in a single entity, which were previously being considered separately. This will improve the Environment Agency and Yorkshire Water’s confidence in Hebden Bridge FAS, produce more accurate information for use in design and enable the long-term costing of proposed assets.
