This was resolved through the design of a multi-stage channel which allows the low flow channel to adjust within a more permanent high flow bank line. Seeded gravels were also allowed to rework naturally to create a wide range of in-channel habitat niches. The two stage channel safely accommodates both the low dry weather flows and the high flood flows. • Ensuring that the river could be re-meandered through contaminated land at the site without increasing remobilisation of in situ contaminated sediments and leachate. An uncontaminated capping layer using uncontaminated soils was used to protect the environment and park users from contaminated materials. • Minimising the need for expensive off-site disposal of contaminated materials and the need to import uncontaminated soils for capping. Soils on the site were categorized as contaminated and less contaminated (i.e. with contaminant concentrations below hazardous levels), and the former were used as a base layer for landscape features within the park. These were capped with less contaminated soils from the site to prevent exposure to the wider environment. 51.374470066104,-0.11206054477952 Tom Croydon Council Sweeney ,, ,,, 11942 Royal HaskoningDHV, Site Location Plan 2013-12-31Z 2456657.5 WANDLE 1.jpg 2009-01-01Z 2454832.5 Complete The River Wandle is located in the southeast of England. It is approximately 14km long with two sources, one at Waddon Ponds (Croydon) and the other at Carshalton Ponds (Sutton). It flowsnorth-eastthrough Croydon, Sutton, Lambeth, Merton and Wandsworth to then join the Tidal Thames. The River Wandle runs under the Wandle Park, in the London Borough of Croydon, for approximately 350mand is only evident by the presence of two man-hole access chambers located within the park’s playing fields. The parkis located at OSgrid reference TQ31681,65563 and covers anarea of 8.5 hectares. Wandle Park is owned and managed by Croydon Council. It is surrounded byamultitude of land-use types including residential, industrial and commercial. The London Borough of Croydon in partnership with the Environment Agency is developing a scheme to restore the River Wandle at Wandle Park, Croydon. The London Borough of Croydon believes that the park is presently an underused asset and wishes to restore the park to reflect is original Victorian lay out. The main objectives of the project are as follows: Restore the river corridor through Wandle Park improving the habitat for local wildlife; Provide flood risk benefit for properties downstream to approximately 1 in 50 return period; Providethe local community with an opportunity to enjoy a high-quality environment and encourage people to care for, use, appreciate and enjoy the environment; Improve the water quality in the channel in support of the Water Framework Directive, helping to meet Good Ecological Potential (GEP) in the catchmentand; Provideflood storagethat will contribute to the London Rivers Action Plan. Update (July 2015) The London Borough of Croydon worked in partnership with Royal HaskoningDHV and LDA Design to oversee the design and implementation of an ambitious scheme to regenerate Wandle Park, improving an important green space into an asset for the local community and contributing towards the delivery of WFD objectives. At the heart of this ambitious £2 million scheme was the restoration of over 250m of the River Wandle, previously culverted below ground, into an open, naturally functioning meandering channel. This project was Highly Commended at the 2015 Landscape Institute Awards. Restoration of Wandle Park restoration of wandle park No London Thames Wandle (Croydon to Wandsworth) and the R.
