A major inundation in the Sandwich and Deal area occurred in January 1953 when a North Sea surge – 4.7m Ordnance Datum (OD) at Pegwell Bay – caused the banks of the River Stour to overtop and breach, resulting in extensive flooding. A surge event occurred in 1976, estimated 1 in 25 (4% annual exceedance probability, AEP) and again in 1983, estimated 1 in 10 to 1 in 5 (10% to 20% AEP), causing flooding at Sandwich Quay with 16 properties suffering direct flooding. A scheme was constructed in 2015 to reduce the risk of flooding to the local community and businesses. The scheme provided a 1 in 200 standard of protection to both banks with 50 years of sea level rise included in the design. This protects 486 homes and 94 commercial properties in Sandwich (Photo 1). It cost £21.7 million, with £11.5 million provided in partnership funding from Kent Country Council and Pfizer. The scheme consisted of 14.4km of strengthening and improving the existing tidal river defences, and creation of a 240ha tidal flood relief area between Sandwich and the mouth of the River Stour. Part of this enabled the creation of 20ha of new Biodiversity Action Plan (BAP) habitat, which includes a mosaic of wetland habitats.
