Assessment of cumulative effects

Small areas of the A83 carriageway within scheme extents are recorded as being high risk (10% chance each year) of surface water and small watercourse flooding. Works will be programmed to avoid periods of adverse weather or heavy rainfall as far as is reasonably practicable.

Vehicles and plant are restricted to the made ground of the A83 trunk road boundary and adjacent embankment, and TM will be designed in line with existing guidance. 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.
