About this subsection
This subsection begins at Lavernock Point on the west shoreline of the Severn Estuary near Penarth in the Vale of Glamorgan and ends at the M48 River Wye crossing at Thornwell, Chepstow.
This area encompasses the developed urban areas of Cardiff and Newport and associated infrastructure including a mainline railway line, electricity transmission networks, A48, M4, major sewerage networks, docks, landfill sites and drainage outfalls. Typically urban areas are defended under Hold The Line, an example of this being the Cardiff Bay Barrage. To the east of the subsection agriculture is a major land use such as the Gwent, Wentlooge and Caldicot levels. There are a number of rivers that discharge into the estuary including the Ely, Taff, Rhymney, Ebbw, Usk and Wye.
The Severn Estuary is subject to numerous international and national nature conservation designations including the Severn Estuary Ramsar, Special Area of Conservation, Special Protection Area and Site of Special Scientific Interest.
