Plans to stabilise the landslide that killed one person in Looe in March have been finalised by Cornwall Council (CC), which is seeking the go ahead on the scheme from affected property owners, the police and the Health and Safety Executive (HSE).
The council has said that if approved the first phase of piling work could start on Monday 20 May and enable St Martin’s Road to be reopened under traffic control ahead of the school summer holidays in July.
Both the B3253 St Martin’s Road and the A387 Sandplace Road were originally closed to traffic following the landslip which happened after heavy rain on 22 March. After initial investigations into the stability of the land, teams from CC’s term maintenance contractor Cormac Solutions carried out resurfacing work to allow Sandplace Road to be re-opened to traffic before. CC said that it has been unable to reopen St Martin’s Road due to concerns over its stability and the ongoing investigation by the HSE.
According to CC, phase one of the stabilisation will involve rock socketing concrete piles into the underlying bedrock at 0.5m centres along a 15m section of the road adjoining the property affected by the landslip. At the same time alternate inclined rock-anchors will be used to provide additional stability, with the whole area then capped with a concrete beam.
These works, which are expected to cost between £100,000 and £150,000 to carry out, will enable the road to be re-opened under traffic light control by 19 July, with further work planned for the winter to allow the road to return to full two-way operation.
