The river Quaggy is 1.7km long and paases through many South London boroughs like Bromley, Greenwich and Lewisham.
The scheme replaced an artificial channel that was fenced off to the public. The hard engineering approach didn't work.
In 1990 the Friends of the Quaggy suggested that it should run through Sutcliffe Park again.
Local people were consulted on the development and design, and were involved extensively in the remodeling.
This renewal took place between 2003 and 2007, and it not only improved the environment, but also created recreational activities for the residents.
Since the flood plain was restored there has been no flooding, and Sutcliffe Park is now the floodplain and the diverging lake, whereas the land was covered in buildings which prohibited infiltration.
