Which agency should be consulted before installing protective lighting adjacent to navigable waters?

The U.S. Coast Guard should be consulted before installing protective lighting adjacent to navigable waters because it plays a critical role in ensuring maritime safety and navigation. The Coast Guard is responsible for maintaining navigable waterways, including assessing the impact of any installations on maritime traffic and ensuring compliance with federal regulations related to navigation aids. Protective lighting can significantly affect visibility and navigation for vessels, potentially creating hazards if not designed or placed properly.

Consulting the Coast Guard ensures that any new lighting does not interfere with navigation channels or confuse mariners. The agency can provide guidance on appropriate lighting types and placement to enhance safety for both land and water users. This consultation is essential for balancing safety requirements with the operational needs of maritime traffic in areas where land-based security measures are being considered.
