River Skerne EU-LIFE project
Key features of the case study
The Skerne demonstration site is located in the town of Darlington, County Durham and demonstrates what can be achieved in an urban environment. The Skerne has been straightened and enlarged to reduce flooding and to drain the surrounding urban area. Much of the floodplain has been raised by old industrial waste tipping, with gas and sewer pipes running alongside the river. As a result of these constraints, restoration opportunities were severely limited - typical of urban rivers elsewhere.
A 2km length of the river has been restored. Four new meanders have been formed in a remaining section of floodplain used as open parkland. The excess soil was used to landscape nearby steep slopes. Riverbanks have been strengthened with willow and reeds to prevent erosion. Thirteen ugly surface water outfalls have been replaced with underground inspection /collection chambers that firstly intercept pollution and then discharge the water into the river below water level.
Elsewhere, where the river could not be re-meandered, it has been enhanced by reshaping and narrowing the bed to vary the flow and to allow riverside plants to flourish. New footpaths and planting schemes complete the theme of "bringing the countryside into town", which locally has been greatly appreciated.
