Children and dogs play along the banks even though the site has still to mature. The marginal planting is suffering disturbance from dogs and children and may take longer than expected to establish a good cover, though this may eventually produce a good diversity of edge habitats. The wildflower plugs have been decimated by crows in search of worms. About a third were removed from the ground and became desiccated. The planting scheme was designed as a balance between creating an instance impact for the local users and allowing natural processes of colonisation to occur. Even so the local users have stated that they would have expected more immediate impact from the planting. The success of the project can be attributed to the multi-disciplinary project team and the Partnership between the Borough Council and the Environment Agency. 51.388414268342,0.026392936706543 Djwebb Dave Environment Agency Webb ,Floodplain reconnection, Increase water retention area,,Deculverting, Increase in-channel hydromorphological diversity, ,,, River Corridor Survey. 13375 London Borough of Bromley Deculverting Norman Park construction.jpg 2000-03-01Z 2451604.5 Complete The Ravensbourne is a spring-fed stream flowing from its source near Keston, on the north slope of the North Downs, northwards through Bromley, Catford and Lewisham to join the Thames at Deptford Creek. In many areas such as Norman Park the stream is confined within a culvert. Culverting of small watercourses in urban and parkland areas has been common in the recent past. Burying the river was felt to reduce the flooding potential, minimise safety issues associated with open water and maximise land available for development or use as open space/playing fields. Little consideration was given to habitat loss, aesthetic and landscape appeal of rivers or the potential benefits of surface water storage. The Ravensbourne flows for 300m through a 1m diameter concrete-lined steel culvert. Smaller land drains, which had been ditches before the area was levelled to form the park, flow into the culvert at intervals along its length. The culvert is crossed close to both its northern and southern ends by park access tracks and major services, with a gas pipeline and electric supply cables crossing the culvert at the north end and a water pipe and local electrical supply cables at the southern end. Deculverting (daylighting) the Ravensbourne would help to restore the corridor by recreating an open channel (in replacement of the culverted section) with diverse in-channel and bankside habitats linking to Scrogginhall Woods just upstream of the park.
