5.14 Dredging of sand and gravel from offshore seabed deposits is a long established practice and large quantities of this material have been landed at wharves in Hampshire for many years. Dredging currently takes place mainly off the Isle of Wight and the West Sussex coast. Dredging areas are usually licensed by the Crown Estate Commissioners and are not subject to planning control. Landings of marine-dredged sand and gravel in Hampshire increased from around 1.5 million tonnes a year in the mid 1970s to over 2.0 million tonnes a year in the late 1980s. Over the years 1985/87/89, landings averaged 2.13 million tonnes a year, but fell to 1.7 million tonnes in 1991 and to 1.6 million tonnes in 1993. Most of this material is used as concreting aggregate. There are ten wharves in Hampshire where marine-dredged sand and gravel has been landed regularly over recent years: five at Southampton; three at Portsmouth; and one each at Fareham and Havant; although two of these wharves are no longer in use.
