Basic: The basic project purpose is to install submerged aquatic structures to grow sea urchins to support coral reef restoration, rehabilitation, and research.

Overall: The overall project purpose is to install temporary submerged aquatic structures into bare substrate to create a sea urchin nursery in support of coral reef restoration, rehabilitation, and research, in waters of the Florida Keys National Marine Sanctuary, Monroe County, Florida.

EXISTING CONDITIONS: The project site is located within open waters of the Atlantic Ocean. The project site, reference as the “Yellow Rock Experimental Plot-Invertebrate Nursery.” The proposed project site has an outer dimension of 33’ by 33’. The sea-bottom composition where the structures are being proposed to be places, are described as bare substrate. The project site has an average water depth of 22’-25’. The project site is within the Florida Keys National Marine Sanctuary (FKNMS) boundaries. The applicant has stated on its application to the Corps that this project has been approved by the FKNMS under permit (FKNMS-2023-019. This site is not associated with any existing coral nursery sites in the area. The sea urchin (Diadema antillarum) is the main targeted species to be grown on site. The project seeks to identify an optimum density of urchins needed on reef habitats that effectively controls algae yet does not damage small coral colonies. No shipwrecks have been identified within the proposed project area.

PROPOSED WORK: The applicant seeks a five-year authorization to install and maintain an underwater sea urchin nursery. Specifically, the applicant seeks authorization to install, maintain and remove, at the end of the project, a maximum of 45, 1-m²/each, submerged aquatic structures/cages within an area of 0.025 acres of bare substrate, at a depth of approximately 25’ and with a vertical clearance of 24’ from the top of each structure to the mean lower water line (MLWL), as depicted on the enclosed project exhibits and supplemental documents (Sheets 1 of 8). 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 of bare sea-bottom. No structure/cages will be deployed touching any coral, sponges, or other living benthic organisms. The applicant has stated that the structures/cages must be deployed over bare reef substrate to allow for coral out-planting. The installation and maintenance work will be conducted during daylight hours only. Hand tools will be utilized to install all structures. The project has been designed in a manner not to result on the aggregation of material or discharge of any fill material that would alter the sea-bottom. No materials will be dredged or discharged as a result of the proposed work. All structures will be removed at the end of the project and the site will be restore to pre-construction conditions.

COMPENSATORY MITIGATION – The applicant is not proposing mitigation because they are not proposing any dredge or fill of surface waters and all water impacts are temporary, waters will be restored to pre-disturbance following completion of the activity. Furthermore, the proposed activities should result in net increases in aquatic resource functions and services.

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.


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), Acorpora sp. and its designated critical habitat, and corals species; (Dendrogyra cylindrus, Orbicella annularis, Orbicella faveolata, Orbicella franksi, Mycetophyllia ferox) species. A no effect determination was reached on smalltooth sawfish critical habitat. 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 1,089-square feet 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.

NOTE: This public notice is being issued based on information furnished by the applicant. This information has not been verified or evaluated to ensure compliance with laws and regulation governing the regulatory program. The jurisdictional line has not been verified by Corps personnel.

COMMENTS regarding the potential authorization of the work proposed should be submitted in writing to the attention of the District Engineer through the Keys Permits Section, 9900 Southwest 107th Avenue, Suite 203, Miami, Florida, 33176, within 21 days from the date of this notice (i.e. on or before February 20th, 2024).
