Bude Canal Regeneration, Cornwall
Flood Risk Assessment and Strategic Flood Study
North Cornwall District Council appointed pdp Green Consulting to undertake two Flood Studies for the regeneration of the historic wharf area, which are located at the sea entrance to the Bude Canal and at helebridge for the redevelopment of an existing amenity. This scheme consists of the restoration of existing historic buildings, the construction of new Craft/Workshop/Retail Units, and the redesign of hard landscape and roadways adjacent to the Wharf.
The site was identified by the Environment Agency (EA) as being within an area at risk of flooding through river and coastal mechanisms and is located in a critical drainage area. Therefore a detailed flood risk assessment was required to accompany the planning application.
The Helebridge site was located at the confluence of the rivers Neet and Stratt, which generated a complex flood mechanism that needed careful analysis. The resulting study enabled the site to be successfully developed whilst mitigating the risk of flooding within the highest risk rated flood risk zone, 3b; The Functional Floodplain.
In Bude, the wharfside and Tourist Information Office were located between the canal and River Neet; in the centre of the floodplain. There were numerous records of these areas flooding and a flood risk assessment was undertaken to establish flow velocities, depth of flooding speed of onset. The modelling was used to establish a development policy for the area and adopt flood proof construction techniques to mitigate the risk of flood damage.
