FLOOD relief construction works for Douglas have moved a step closer with tenders for the works being published.

The works, which include a new culvert in Togher will include the construction of direct flood defences and conveyance improvement measures along the Ballybrack Stream, Grange Stream and Tramore River. 

The direct defences proposed include flood walls and embankments with the conveyance improvements consisting of channel widening, channel deepening and the introduction of or replacement of culverts.

The area was hit by major flooding in June 2012 which extended extending throughout Douglas and Togher. There was significant damage caused to residences in the Ravensdale area, as well as in Douglas village centre - including the Douglas Village Shopping Centre - the St Patrick’s Mills centre, Donnybrook Commercial Centre and commercial properties in Togher. 

There was also significant damage to community and amenity facilities.

Construction works for the proposed scheme will take place in four separate areas along the Tramore River, Ballybrack Stream and Grange Stream and are expected to begin in late summer.

A culvert underneath Church Road will be replaced with flood defence walls planned for Ravensdale.

Douglas-based councillors have repeatedly voiced their frustrations at delays in the project and the costings which have ranged from €6m to over €13m for the finalisation of the project.

The scheme has been previously complicated by knotweed along the riverside but consultants ARUP said they have taken a “proactive” approach to the issue and have an invasive species management plan in place for construction.

Works may also involve the diversion of a 600mm water main as advance works to mitigate the risk of clashing with a live water main during construction.
