The Shimna Flood Alleviation Scheme project involves the construction of a fluvial flood defence in Newcastle, 27 miles outside Belfast, with an envisaged construction period of 12 months. The flood defence extends both upstream and downstream of the River Shimna for a total length of 1.45km comprising a combination of sheet pile flood walls (approx. 0.45km), secant pile flood walls (approx 0.89km) and piled earth embankments (approx. 0.11km).

The works also include the demolition of a number of property boundary walls and fences, the relocation of a drainage ditch, construction of new pathways, wall cladding, a retaining wall, back drainage, landscaping, the erection of a flood gate and river works.

Newcastle has a history of flooding, particularly after heavy, sustained rainfall – there was major flooding in the area in August 2008.

Major flooding occurred on 25 and 26 August 2020 when the Shimna River burst its banks during Storm Francis.

Commenting at the time in response to the flooding, Infrastructure Minister Nicola Mallon said that work on a flood alleviation scheme for the Shimna River was due to start in the summer of 2021. This has now been brought forward.
