Vulnerability of the project to risks

There are numerous areas throughout the scheme extents that have a high likelihood of river flooding and surface water and small watercourses flooding. Works will be programmed as far as is reasonably practicable to avoid periods of adverse weather or heavy rainfall.

Works are restricted to areas of engineered ground on the A9 trunk road and TM will be designed in line with existing guidance. TM will consist of single lane closure in lane two of the northbound carriageway with a temporary speed limit of 50mph, and 30mph within working areas. Local residents will be notified of working hours and provided with appropriate contact information.

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.

The works will not result in any change in vulnerability of the A9 carriageway to risk, or in severity of major accidents/disasters that would impact on the environment. The replacement/ installation of new VRS is designed to protect users of the A9 trunk road and will have a beneficial impact on road users.

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.
