Vulnerability of the project to risks

Areas of the A828 carriageway within the scheme extent are recorded as having high risk (10% chance each year) of coastal, surface water and small watercourse flooding. Works will be programmed as far as is reasonably practicable to avoid periods of adverse weather or heavy rainfall. There will be no increase to the likelihood of flooding on the A828 within the scheme extents upon completion of the works.

Works are restricted to the made ground of the A828 trunk road boundary and TM will be designed in line with existing guidance. TM will consist of road closure (19:00-06:00) with amnesties at 20:00, 21:00, 22:00, 23:00, 00:00, 02:00 and 04:00, using nighttime working. Where required, alternative NMU provisions/routes will be included in the TM 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.
