Project summary
This project was the first in Thames Region to be delivered by the Environment Agency using funding from the Office of the Deputy Prime Minister’s (ODPM, now DCLG) Sustainable Communities Fund.
In May 2004 we submitted a bid to the ODPM for £1million to undertake a series of environmental enhancements along the River Roding in its lower reaches where it passes through the London Boroughs of Barking & Dagenham and Newham. The funding bid was approved in October 2004 and the project had to be delivered by the end of the funding period in March 2006. A number of environmental and amenity enhancements were delivered by this project. These included improved habitat for wildlife (including provision of Biodiversity Action Plan (BAP) habitats), improved access to waterside areas, new seating/viewing areas, retreated and renewed flood defences and increased flood storage capacity.
This is an area of London where development has historically lead to the degradation of habitats along the River Roding and its tidal confluence with the Thames. It is therefore important that BAP habitat such as saltmarsh and mudflat is restored to the Creek.
BACKGROUND
The River Roding is a tributary of the River Thames. It rises to the north east of London and flows south through East London, through and along the boundary of a number of London Boroughs, before joining the River Thames in Barking. The lower reaches of the River Roding are tidal and the land adjacent to the River Roding throughout the project area is protected from tidal and fluvial flooding by flood defences. In addition to these defences the Barking Barrier protects the area from extreme high tides. This barrier is part of the Thames tidal defences. The Barking Barrier is situated at the confluence of the River Thames and the River Roding.
The Lower Roding Regeneration Project covers 4.5km of the River Roding where it flows through the London Boroughs of Barking and Dagenham and London Borough of Newham, between grid references TQ 436848 and TQ 458816.
The lower reaches of the River Roding are extremely urbanised and many of the riverside areas are of low environmental quality with poor aesthetic appeal and are difficult to access. Infrastructure barriers currently make it a difficult landscape to easily navigate and enjoy. These barriers include a railway line crossing and the A13 trunk road, creating east-west barriers, and the A406 North Circular Road running parallel to but set back from the west bank of the river.
