The zone is approximately 580m long and 50m wide; it is bounded upstream by St Saviours Dock and ends just upstream of Cherry Garden pier. There is a single access point to the zone at Fountain Stairs: these are of modern concrete, with a handrail. The ground conditions on the site are generally firm (gravels) with considerable deposition at the top of the foreshore. The area immediately in front of Chambers Wharf can be hazardous with some unstable surface areas.
