Transportation Mitigation Measures

Mitigation measures to avoid or reduce transportation impacts from hydrokinetic energy 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 boat and vessel traffic and vehicular traffic associated with a project. Many impacts can be reduced or avoided when considered during the siting and design phase.

Develop a final set of mitigation measures for any project in consultation with the appropriate tribal governments, federal and state resource management agencies, local governments, and 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:

  • Conduct a navigational safety and risk assessment and consult with the Coast Guard.
  • Locate the hydrokinetic energy facility to assure no interference with designated shipping lanes and important fishing areas.
  • Prepare an access road siting study and management plan that incorporates road design, construction, and maintenance standards.
  • Use existing roads to the extent possible.
  • 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 hydrokinetic energy development include:

  • Deploy navigational aids such as lighting and foghorns to minimize vessel collisions with hydrokinetic energy devices.
  • Place signs along roads to identify speed limits, travel restrictions, and other standard traffic control information.
  • Limit traffic to roads designated specifically for the project.
  • Limit use of unimproved roads to emergency use only.
  • 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 to local commuters.
  • After the heavy construction period is over, restore roads to a condition equal or better to that before project construction.
