7.9 Watercourses and Wetlands

7.9.1 A watercourse or wetland, including ponds and dubs, can be affected by building or engineering operations (either during or after completion of works) or new uses of land which are carried out anywhere within the catchment area. New development in the vicinity of such areas can result in pollution, sedimentation or direct deterioration. Land infill and tipping, mineral exploitation, large scale developments and activities which disturb contaminated material are of particular concern. In all but the most minor proposals, consideration will be given to the protection of watercourses and wetland areas which may be affected by a proposed activity. In addition to requiring planning permission, any work on a watercourse, stream or designated Main River (and normally including the banks for a distance of 9m (30ft) either side) requires the permission of the Department of Transport's Land Drainage Engineer, in accordance with the Land Drainage Act 1934.
