PROJECT PURPOSE:

Basic:  The basic project purpose is to install temporary structures for coral propagation for marine restoration, research, and habitat enhancement.

Overall:  The overall project purpose is to continue the development of a stablished coral nursery for the purpose of coral propagation for restoration, enhance of the marine environment and to conduct research in waters of the Florida Keys National Marine Sanctuary, Monroe County, Florida.

 

EXISTING CONDITIONS:  The project site is located within federal open waters of the Atlantic Ocean.  The project site is referred to as “Mote-Looe Key Coral Nursery” site.  The Mote-Looe Key coral nursery site is approximately 5.6 acres on size.  The current developed footprint at the site is approximately 0.96 acres, with an outer dimension of 200’ by 190’, 38,000-square feet.  Currently, the project site supports 259-coral tree like mid-water structures and 50 coral modules on the sea floor. A variety of ESA-listed species are currently being propagated at this site.  The project site sea-bottom consists of a sand composition and has an average water depth of 27’-29’’. No natural occurring corals, hardbottom or seagrass were identified within the project area.  The project site is within the Florida Keys National Marine Sanctuary (FKNMS) boundaries. The site was previously permit by the FKNMS under FKNMS Permit # 2021-171 and #2021-172.

 

PROPOSED WORK:  The applicant seeks authorization for a 10-year permit to continue the development of an established open water coral nursery site for the purpose of coral propagation.  A variety of different coral species will be grown at this site, including ESA-listed species such as (Acropora cervicornis, Acorpora palmata, Orbicella faveolate and Orbicella annularis). Specifically, the proposed work consists of the temporary deployment of a maximum of 400 structures at any one given time over the duration of the Corps authorization, 10 years.  The proposed structures will occupy no more than 1.4 acres, 25%, of the total proposed 5.6 acres project site boundaries at any given one time.  The proposed structures will consist of both, suspended off the bottom coral “trees” and PVC/concrete “modules.” The “trees” structures will be constructed of 1” diameter PVC “spines” (5’ tall) and 3/8” fiberglass rod “arms” (3’ long) anchored to the seafloor using 3/8” polypropylene “trap line” attached to a 1100 lb “duckbill” anchor driven 36” into the sand bottom. The entire structure is supported off the seafloor using (2) 7.5” styrofoam floats. Corals are then suspended from the fiberglass rod “arms” using 130lb monofilament line.  The coral “Modules” structures will be constructed of 1” diameter PVC “risers” (1’ tall) embedded in 2” thick poured concrete slab which is anchored to the sand bottom by driving a 4ft length of ½” rebar approximately 3ft down through a center hole in the module. Corals are then mounted on ½’ thick x 3” diameter concrete poured “discs” using an underwater epoxy and affixed to the top of the coral modules using a 1” PVC slip cap, allowing for easy removal and cleaning of the fragment.  Additionally, the applicant seeks authorization to install a maximum of 12 grazer (crab) cages, for in-situ grow-out of Caribbean King Crab (Maguimithrax spinosissimus).  Each cage will be a maximum of 8 ft. long x 4 ft. high x 4 ft. wide and constructed from 1.5” (internal) diameter schedule 40 PVC pipe filled or partially filled with Type II Portland cement. The cages will be wrapped in either 0.25”, 0.38”, or 0.5” mesh size heavy aquaculture plastic mesh affixed to the PVC frame with heavy duty plastic cable ties. Each cage will feature a hinged section on top to serve as an access point that will be secured with heavy monofilament (1000 lbs test) and aluminum bolt snaps/carabiner clips. Each cage will feature three 8’ x ½” diameter lengths of rebar along each long side – six total per cage – which will be driven 36” into the seafloor such that the bottom of the cage is no less than 12” off the seabed. Immediately adjacent to each rebar leg, a 36” sand/screw or “duckbill” anchor (with 36” 1000 lb. monofilament tether) will be driven 36” into the seafloor and used further secure each leg with a 3/8” twisted polypropylene (trap) line around the bottom frame rail of the cage structure. These twisted poly lines will be affixed to the rebar legs using cable ties to avoid any entanglement risks. Each cage will sit no less than 12” off the seafloor and vertical clearance above each cage will range 22-24 feet. All structure shall be removed at the end of the project and the site shall be restore to pre-construction conditions. The project is further described in the enclosed project exhibits and supplemental document (8-pages).

 

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 coral nursery structures is proposed on areas of sandy bottom only, areas that do not support hard bottom, corals and/or seagrass.  Furthermore, the project has been designed to maintain safe navigability by maintaining a clearance between MLW and the top of any of the proposed structures. The project has been designed in a manner not to result on 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. 

 

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 aware of recorded historic resources within or adjacent to the permit area and 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. 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 rays, smalltooth sawfish (Pristis pectinata), Oceanic Whitetip shark (Carcharhinus longimanus), Blue whale (Balaenoptera musculus), humpback whale (Megaptera novaeangliae), fin whale (Balaenoptera physalus), sei whale (Balaenoptera borealis), right whale (Eubalaena glacialis), sperm whale (Physeter macrocephalus), 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 5.6 acres of sand submerged 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.
