Project summary
The Chapel Beck (main river) flows through Guisborough (Map 1) and is fed by a number of small tributaries (ordinary watercourses). There is significant modelled flood risk from the chapel beck but few instances of actual flooding, although the tributaries have caused flooding in the past. The project has so far determined that the reason for the lack of flooding from the beck is likely to be a large number of unaccounted for natural and unintentionally created attenuations upstream of the town. The project is seeking to formalise and improve these existing attenuations and to create further attenuations to reduce future flood risk, while creating 5ha of water dependent habitat.
Installing 15,000m3 of flood water storage in the catchment could reduce the 100-year peak flow by 10.9% (2m3s-1).
The published flood map cannot take account of the man-made attenuations present in the catchment because there is no guarantee that these will perform this inadvertent flood water storage function in perpetuity. Only if the features are formalised as flood risk assets and maintained can they be considered when estimating the actual flood risk to homes in Guisborough.
