Early Notice and Public Review for a Proposed Activity in the 100-Year Floodplain Recapitalization of Moorings and Facilities at USCG Sector Jacksonville Annex, Florida To: All interested residents of Jacksonville, Florida; residents of Duval County, Florida; elected officials, agencies, groups, and individuals Date: May 31, 2026 This is to give notice that U.S. Coast Guard (USCG) has determined that the following action is located in the 100-year floodplain, and the USCG will be identifying and evaluating practicable alternatives to locating the action in the floodplain and the potential impacts on the floodplain from the proposed action, as required by Executive Order 11988, Floodplain Management. The USCG proposes to recapitalize the waterfront infrastructure at Sector Jacksonville Annex. These improvements are intended to address existing damage and structural deficiencies at the bulkhead, pier and buildings at the Sector Jacksonville Annex. The existing bulkhead and pier would be repaired and portions would be replaced. Additionally, the existing structures at the Annex would be replaced with flood-hardened, 25,000-square-foot Multi-Mission Building. There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment are given an opportunity to express any concerns, suggest alternative methods to serve the same project purpose, and identify methods to minimize and mitigate impacts. Second, this notice is an important outreach tool to disseminate information and request comment about floodplains which can facilitate and enhance Federal efforts to reduce risks and impacts associated with floodplains. Third, when the Federal government determines it will participate in actions taking place in floodplains, it must inform those who may experience greater or continued risk associated with floodplain management. The USCG has prepared a Draft Environmental Assessment (EA) that includes a full description of the proposed action and documentation of potential impacts related to floodplains. The Draft EA may be found here: https://www.dcms.uscg.mil/Our-Organization/Assistant-Commandant-for-Engineering-Logistics-CG-4-/Program-Offices/Environmental-Management/Environmental-Planning-and-Historic-Preservation/Article/4478629/notice-of-availability-for-the-public-draft-environmental-assessment-for-the-re/ Written comments must be received by Richard Hylton at Rick.D.Hylton@uscg.mil by 5:00 pm EDT on June 14, 2026.
