    Impact of the work

    For the safety of the public, the worksite safety measures may sometimes result in hindrances on roads, bicycle paths, parking lots and properties located within the power line right-of-way. These intermittent hindrances may last anywhere from ten minutes to three days.

    The work is not ever expected to lead to a power outage. If such a situation were to occur, however, the affected residents would be informed by an automated telephone messaging system.

    Mitigation measures

    A traffic plan has been established, in cooperation with the municipal authorities, to facilitate the movement of cars, cyclists and pedestrians.

    When detours are required, appropriate signage will be in place.

    With few exceptions, access to homes will be maintained

    The work will comply with the environmental standards in effect.
