Regulated Navigation Areas; Escorted Submarines Sector Jacksonville Captain of the Port Zone
The Coast Guard is establishing regulated navigation areas (RNA) covering the St. Marys Entrance Channel, portions of the Cumberland Sound, and the Atlantic Ocean that will be in effect whenever any Navy submarine (foreign or domestic) is escorted by the Coast Guard and operating within the jurisdictional waters of the Sector Jacksonville Captain of the Port Zone. These RNAs are necessary to help ensure the safety and security of submarines, their Coast Guard escorts, and the public. The RNAs will do so by requiring all persons and vessels located within an RNA to follow lawful orders and/or directions given to them by Coast Guard designated representatives. Additionally, these RNAs will supersede the current temporary safety/security zone for Cumberland Sound, Georgia and St. Marys River Entrance Channel.
Changes in Flood Hazard Determinations
New or modified Base (1-percent annual chance) Flood Elevations (BFEs), base flood depths, Special Flood Hazard Area (SFHA) boundaries or zone designations, and/or regulatory floodways (hereinafter referred to as flood hazard determinations) as shown on the indicated Letter of Map Revision (LOMR) for each of the communities listed in the table below are finalized. Each LOMR revises the Flood Insurance Rate Maps (FIRMs), and in some cases the Flood Insurance Study (FIS) reports, currently in effect for the listed communities. The flood hazard determinations modified by each LOMR will be used to calculate flood insurance premium rates for new buildings and their contents.
