The West London Dyke is 2,374 m long and runs along the west bank of the North Branch of the Thames River from Oxford Street to the forks of the Thames River and then along the west bank of the Main Branch to the west side of the Wharncliffe Road Bridge. The City of London owns the dyke and through an agreement, the Upper Thames River Conservation Authority (UTRCA) undertakes major maintenance activities.
The UTRCA retained Stantec Consulting Ltd. in 2009 to complete a Master Repair Plan covering the next 20-year period to address aging infrastructure, flood protection, public use, and integration of other City initiatives. The study was placed on hold in early 2013 pending updates to flood elevation information. With new information now available, Stantec is in the process of completing the Master Repair Plan.
