Coast Guard Expands Puerto Rico Base's No-Fly Water Zone
Published Date: 12/4/2025
Rule
Summary
Starting January 5, 2026, the Coast Guard is updating the security zone around their Base San Juan in Puerto Rico to keep everyone safe from possible threats. Boats and people can’t enter the area within 200 feet of the base’s water edge unless they get special permission. This change tightens security without blocking important boat traffic, so it’s a win for safety and smooth sailing!
Analyzed Economic Effects
5 provisions identified: 4 benefits, 1 costs, 0 mixed.
200‑Foot Security Zone Restricts Access
Starting January 5, 2026, no vessel or person may enter, transit through, or remain in the waters within 200 feet seaward from the water's edge of Coast Guard Base San Juan unless authorized by the Captain of the Port, Sector San Juan or a designated representative. The zone is defined by coordinates with easternmost point 18°27'39" N, 066°06'56" W and westernmost point 18°27'46" N, 066°07'07" W.
Security Zone Reduced to Avoid Channel
The final rule reduces the prior security zone so it does not encroach upon the navigable channel and instead establishes a uniform 200‑foot distance from the base's water edge to minimize interference with vessel traffic. This change is effective January 5, 2026.
Authorization Process for Entry
If you need to enter the security zone, you must obtain permission from the Captain of the Port, Sector San Juan or a designated representative; request authorization by phone at (787) 289-2041 or via VHF-FM channel 16. Those in the zone must follow lawful orders from the COTP or designated representative.
No Physical Barriers Will Be Installed
The Coast Guard will not install barriers or boundaries at Base San Juan to prevent inadvertent crossings because barriers could interfere with operations; the rule relies on the 200‑foot security zone and signage/administrative measures instead.
Coast Guard Says Small Businesses Won't Be Significantly Hurt
The Coast Guard certifies this rule will not have a significant economic impact on a substantial number of small entities because vessel traffic can safely transit around the small area limited to 200 feet from the base. This certification appears in the Regulatory Flexibility Act analysis.
