Vulnerability of the project to risks

Small areas of the A85 carriageway within scheme extents are recorded as being low to high risk (0.1 to 10% chance each year) of surface water and small watercourse flooding. Although the trees along the verges participate in flooding reduction by slowing down the flow of rainwater, absorbing rainwater and reducing erosion, it is not expected that removal of the trees will significantly impact local flooding due to the presence of the road drainage system and remaining vegetation. Works will be programmed to avoid periods of adverse weather or heavy rainfall as far as is reasonably practicable.

Works are restricted to the trunk road boundary and the embankment to the east of the A85 carriageway. TM will be designed in line with existing guidance. TM will consist of lane closures facilitated by two-way temporary traffic lights during the daytime. Where required, alternative NMU provisions/routes will be included in the traffic management setup, to minimise impact of the works on NMUs.

A Traffic Management Plan (TMP), which includes measures to avoid or reduce disruption to road traffic, will be produced in accordance with the Traffic Signs Manual (Department of Transport, 2009). The TMP will ensure that there is no severance of community assets, access routes or residential development.

These measures, along with mitigation measures and standard working practices, will be detailed in the SEMP and adhered to on site. The vulnerability of the project to risks of major accidents and disasters is considered to be low.
