The shoreline of the North Norfolk coast between Sheringham and Blakeney Point is characterised by a natural upper shingle ridge beach. Between Sheringham and Kelling Hard the beach is backed by glacial cliffs, but to the west of Kelling Hard the single ridge fronts an area of freshwater marshes which were progressively reclaimed from saltmarshes in the 17th and 18th centuries. These coastal marshlands are separated from the rising ground of the Cromer Ridge to the south by the A149 coast road and the settlements of Cley and Salthouse. The River Glaven runs by Cley on its route to the sea, but is then deflected westwards for 6 kilometres by the presence of the sand and shingle spit leading to Blakeney Point. The whole of the coastal plain and lower reaches of the Glaven valley are below the 5.0 metre contour, and therefore within the tidal flood risk area. A capital scheme for improving the standard of defence for most of Cley village and the valley of the River Glaven was completed in 1995. This comprised the construction of a. new clay ring embankment with a tidal gate structure where it crosses the Glaven estuary. However, the only means of protection against tidal flooding for the area of low lying land between Cley and Kelling Hard remains a 5.5 kilometres quasi-rnatural shingle ridge. The area at risk includes 35 properties located at the eastern edge of Cley and in Salthouse village, the A149 coast road and 300 hectares of freshwater marshes. Investigations and consultations have been undertaken in order to make a comparison of the relative merits of different strategic options of the future management of the defences along this frontage.
