Transportation Mitigation Measures

Mitigation measures to avoid or reduce transportation impacts from low-head hydropower development.

The following are examples of mitigation measures that could be applied to reduce transportation impacts of a project depending upon site- and project-specific conditions. Transportation impacts are related to the amount and types of vehicular traffic associated with a project. Many impacts can be reduced or avoided when taken into account during the siting and design phase.

Develop a final set of mitigation measures for any project in consultation with the appropriate federal resource management agencies and with stakeholders. Conduct these consultations as part of the project development process and preferably prior to final project siting and design.

Siting and Design Mitigation Measures

Siting and design considerations that mitigate impacts include:

  • Prepare an access road siting study and management plan that incorporates road design, construction, and maintenance standards.
  • Plan to use existing roads to the extent possible.
  • Develop a transportation plan, particularly for oversized and overweight components.
  • Develop a traffic management plan for site access roads and for use of main public roads. The plan should incorporate consultation with local planning authorities regarding traffic, in general, and specific issues, such as school bus routes and stops.

General Mitigation Measures

General mitigation practices and principles that could apply to any or all phases of low-head hydropower development include:

  • Limit traffic to roads designated specifically for the project.
  • Place signs along roads to identify speed limits, travel restrictions, and other standard traffic control information.
  • Instruct and require all personnel and contractors to adhere to speed limits to ensure safe and efficient traffic flow.
  • Limit construction vehicle traffic on public roadways to off-peak commuting times to minimize impacts on local commuters.
  • Limit use of unimproved roads to emergency use only.
  • Restore roads to equal or better condition than before project construction after the heavy construction period is complete.
  • Control dust along unsurfaced roads, especially near residences and farm fields.
