PROJECT PURPOSE:
Basic: The basic project purpose is marine habitat enhancement and increase fishing and diving opportunities.
Overall: The overall project purpose is the development of an artificial reef with approved materials to enhance the marine environment and create new habitat for marine organisms, including fish, within the offshore waters of the Gulf of Mexico, in Monroe County, Florida.
EXISTING CONDITIONS: The proposed artificial reef site, to be known as the Gulfside Five Mile Reef, is located within open waters of the Gulf of Mexico, outside of the Florida Keys National Marine Sanctuary (FKNMS) boundaries. The proposed site is comprised of unconsolidated sand bottom, and the approximate depth of water within this site is approximately 42’ relative to mean low low water (MLLW). The Florida Fish and Wildlife Conservation Commission (FWC) divers surveyed the proposed project area and its vicinity and did not identify any natural hardbottom or submerged aquatic vegetation (SAV). According to the most recent benthic survey, conducted on June 26, 2024, by FWC, the submerged bottom within the proposed project site is being identified as unconsolidated sand bottom. The proposed site is outside the historic shrimping activities. No shipwrecks have been identified within the proposed project area.
PROPOSED WORK: The applicant seeks a 10-year Corps authorization to construct an offshore artificial reef to be known as the Gulfside Five Mile Reef. The proposed artificial reef site area would measure 0.25 nautical miles by 0.25 nautical miles, encompassing a total area of 53 acres of submerged sand sea-bottom of which less than 1 acre of artificial reef material footprint would be deployed during the lifetime of the permit. The proposed navigational clearance is -25’ MLLW. All artificial reef materials will be consistent with the approved Gulf and Atlantic States Marine Fisheries Commission publication “Guidelines for Marine Artificial Reef Material, 3rd edition”, as well as NOAA’s ‘National Artificial Reef Plan’, and FWC’s ‘State of Florida Artificial Reef Strategic Plan’. Please see enclosed supporting detailed description of the proposed work and associated work plans. The proposed project is in waters of the United States.
AVOIDANCE AND MINIMIZATION INFORMATION – The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:
Due to the nature of the work, the applicant could not avoid conducting the proposed work within waters of the United States. The deployment of the proposed structures is proposed on areas devoid of submerged aquatic vegetation (SAVs), areas that do not support natural rock outcrops or hard-bottom. Material will be deployed on sand sea-bottom and a buffer area of at least 200-feet will be maintained from any submerged aquatic resources, if present. The proposed work will be conducted during daylight hours only. No materials will be dredged as a result of the proposed work. All reef materials will be clean and free from asphalt, petroleum, other hydrocarbons and toxic substances. All reef materials will be selected, designed, constructed, and/or modified to create stable and durable marine habitat that will not be an entanglement hazard. Individual artificial reef materials shall weigh a minimum of 500 pounds to ensure stability of deployed structures/material.
COMPENSATORY MITIGATION – The applicant is not proposing compensatory mitigation because impacts to special aquatic sites are not proposed, the proposed activities should result in net increases in aquatic habitat functions and services. Any impacts from the proposed project are anticipated to be positive by creating new habitat for feeding, refuge, and reproduction of many marine organisms.
CULTURAL RESOURCES: The Corps is evaluating the undertaking for effects to historic properties as required under Section 106 of the National Historic Preservation Act. This public notice serves to inform the public of the proposed undertaking and invites comments including those from local, State, and Federal government Agencies with respect to historic resources. Our final determination relative to historic resource impacts may be subject to additional coordination with the State Historic Preservation Officer, those federally recognized tribes with concerns in Florida and the Permit Area, and other interested parties.
ENDANGERED SPECIES:
The U.S. Army Corps of Engineers (Corps) has determined the project may affect but is not likely to adversely affect (“MANLAA”) the West Indian manatee (Trichechus manatus) and would not adversely modify its designated critical habitat. Since the proposal by the applicant is for in-water construction, potential impacts to the endangered West Indian manatee were evaluated using Corps of Engineers, Jacksonville District, and the State of Florida Effect Determination Key for the Manatee in Florida, April 2013 (Key). Use of the Key resulted in the sequence A-B-C-G -N-O-P (5) “may affect, not likely to adversely affect”, where no further consultation with the Service is necessary. This determination is based on the applicant following the standard Manatee construction conditions for the proposed activity. The U.S. Fish and Wildlife Service (FWS) has given concurrence with this determination pursuant to Section 7 of the Endangered Species Act. No further coordination with the FWS is required.
The Corps has determined the proposed project may affect but is not likely to adversely affect (“MANLAA”) the Swimming green sea turtles (Chelonia mydas), loggerhead sea turtles (Caretta caretta) and their designated critical habitat, hawksbill sea turtles (Eretmochelys imbricata), kemps ridley sea turtles (Lepidochelys kempii), leatherback sea turtles (Dermochelys coriacea), Nassau grouper (Epinephelus striatus), Giant Manta ray (Manta birostris), smalltooth sawfish (Pristis pectinata), Oceanic Whitetip shark (Carcharhinus longimanus). A no effect determination was reached on smalltooth sawfish critical habitat, Acorpora sp. and its designated critical habitat, and corals species; (Dendrogyra cylindrus, Orbicella annularis, Orbicella faveolata, Orbicella franksi, Mycetophyllia ferox) species. The Corps will request National Marine Fisheries Service concurrence with these determinations pursuant to Section 7 of the Endangered Species Act.
ESSENTIAL FISH HABITAT (EFH): This notice initiates consultation with the National Marine Fisheries Service on EFH as required by the Magnuson-Stevens Fishery Conservation and Management Act 1996. The proposal would impact approximately 53 acres of submerged sea bottom utilized by various life stages of marine species. Our initial determination is that the proposed action would not have a substantial adverse impact on EFH or Federally managed fisheries in the Florida Keys. Our final determination relative to project impacts and the need for mitigation measures is subject to review by and coordination with the National Marine Fisheries Service.
Navigation: The proposed activity is not located in the vicinity of a federal navigation channel.
SECTION 408: The applicant will not require permission under Section 14 of the Rivers and Harbors Act (33 USC 408) because the activity, in whole or in part, would not alter, occupy, or use a Corps Civil Works project.
