PROJECT PURPOSE:

 

Basic: The basic project purpose is to enhance marine fishery resources.

 

Overall: The overall project purpose is to create essential fish habitat and enhance nature-based tourism by continuing to expand the existing artificial reef network off the coast of Hernando County with the natural submerged aquatic vegetation and hardbottom habitat offshore within the Gulf of Mexico.  

 

EXISTING CONDITIONS: Water & Air Research, Inc. (Water & Air) and their sub-consultant team, CSA Ocean Sciences Inc. (CSA), Morgan & Eklund, Inc. (M&E), and INTERA, were contracted by the Hernando County Board of County Commissioners to identify potential artificial reef sites off the coast of Hernando County. Between August and October 2022, site assessments conducted utilized aerial photography, side scan sonar, multibeam bathymetry, magnetometer sensors, photos and videos, sediment samples, and SCUBA diver observations. A total of three (3) midshore deployment sites within the proposed footprint were evaluated.
 

SCUBA diving site assessments were conducted between September and October 2022. Sites were assessed using methods suitable for the location. Midshore sites had variable bottom types and were not in defined shapes. Therefore, an anchor with buoy was placed at the center point where transects crossed. Each midshore site consisted of four (4) transects. The three (3) midshore sites evaluated were described as irregularly shaped, bare substrate with scattered patches of hard bottom. Calcareous green algae species (Udotea sp. and Caulerpa sp.) were present at all evaluated midshore sites. Red algae and small patch of shoal grass (Halodule wrightii) were present at Mid 34, but no corals or sponges were observed along the transects. The average sediment depth of the Mid 34 site was 20.2 cm and consisted mostly of fine sand, medium sand, and gravel (material greater than 3.35 mm), as well as shell hash.
 

PROPOSED WORK: The applicant seeks authorization to construct a new midshore artificial reef located approximately 14 miles off the coast of Hernando Beach, Hernando County, Florida. The proposed reef will encompass an area of approximately 3.189 acres (138,912 SF). A total of 76 pallet reef balls, each weighing approximately 1,300 pounds, will be deployed within the 1,540.0 ft perimeter footprint. Reef balls deployed at this site will measure approximately 4.5-ft tall by 6.0-ft wide and will have a total height of less than half of the water column. Project design is depicted in Attachment 1.

 

Hernando County Parks and Recreation Department’s Waterways and Aquatic Services office located at 4146 Pine Dale Court, Hernando Beach, FL, 34607, will serve as the primary staging area / launching area for equipment necessary to deploy the reefs. Transport vessels will utilize the Hernando Beach Channel, a fully marked navigation channel, to travel from the staging area to the offshore channel entrance. Transport vessels will utilize a Geographic Positioning System and an electronic depth display to identify deployment sites. Once at the deployment location, a crane aboard the transport vessel will individually lower each reef ball into the water. SCUBA divers and in water personnel will ensure each reef ball is strategically placed, in order to avoid potential aquatic resources and essential fish habitat in the surrounding vicinity. Deployment of reefs will occur during daylight hours when weather conditions are determined to be suitable. Buoys will be installed that clearly define the boundary of each deployment area prior to deployment of the reef structures. Buoys will be immediately removed, following reef deployment.

 

The south midshore artificial reef project is proposed in concurrence with three (3) other artificial reef sites. Hernando County is proposing to create one (1) nearshore artificial reef (SAJ-2023-00708), one (1) north midshore artificial reef (SAJ-2024-00858), and one (1) offshore artificial reef (SAJ-2024-00859).

 

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:

 

All reef material will be constructed of clean concrete structures and/or limestone rock, free from asphalt, creosote, petroleum, other hydrocarbons and toxic residues, loose free-floating material or other deleterious substances. Reef pallets will be positioned on sand and shell hash substrates. The deployment site was selected due to the applicant’s ability to place reef pallets in areas that avoid surrounding SAV, corals, and macroalgae. Structures will be configured and constructed to be stable in a 25-year return interval storm event at the depth of placement. No dredging is proposed or authorized for the placement of the structures. As the clean artificial reef materials are deployed, any turbidity will be minimal, temporary, and localized near the seafloor surface during initial reef placement.

 

COMPENSATORY MITIGATION – The applicant has provided the following explanation why compensatory mitigation should not be required:

 

Three (3) sites were analyzed for potential artificial reef locations using aerial photography, side scan sonar, multibeam bathymetry, magnetometer sensors, photos and videos, sediment samples, and SCUBA diver observations. The applicant selected two (2) viable deployment locations within the proposed footprint based on the substrate, sediments, and minimal essential fish habitat present within each deployment location. The north midshore site (Mid 15) is currently being reviewed under Corps authorization SAJ-2024-00858. Based on this information, compensatory mitigation should not be required for the proposed project. The Corps will therefore not require mitigation unless additional information is provided that would indicate the need to mitigate for adverse effects.
 

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 Corps determined the proposed project may affect but is not likely to adversely affect (MANLAA) the West Indian manatee or its designated critical habitat, managed by U.S. Fish and Wildlife Service (USFWS). The project is located within manatee consultation area but is not within Important Manatee Area (IMA) or Warm Water Aggregation Area (WWAA). Use of The Corps of Engineers, Jacksonville District, and the State of Florida Effect Determination Key for the Manatee in Florida, April 2013 and Addendum dated May 13, 2019, resulted in the following sequence: A > B > C > G > N > O > P > MANLAA. Pursuant to the key, no further consultation with USFWS is required. The applicant agrees to adhere to the 2011 Standard Manatee Conditions for In-Water Work.

 

The Corps has determined the proposed project may affect but is not likely to adversely affect loggerhead sea turtles (Caretta caretta), Kemp’s ridley sea turtles (Lepidochelys kempii), green sea turtles (Chelonia mydas), hawksbill sea turtles (Eretmochelys imbricata), leatherback sea turtles (Dermochelys coriacea), Smalltooth sawfish (Pristis pectinata), gulf sturgeon (Acipenser oxyrinchus desotoi), and giant manta rays (Manta birostris). The Corps evaluated the proposed work utilizing NMFS’s Jacksonville District’s Programmatic Biological Opinion (JAXBO) dated 20 November 2017, including consideration of the Project Design Criteria (PDCs) identified in the JAXBO that have typically been applied to permitted in-water construction activities. These PDCs ensure effects of in-water construction activities are minimal in nature and do not result in adverse effects to listed species or to essential features of designated critical habitat. As established in JAXBO, the Corps determined that the proposed artificial reef project may affect but is not likely to adversely affect swimming sea turtles, Smalltooth sawfish gulf sturgeon, or giant manta rays. The Corps will request National Marine Fisheries Service programmatic concurrence with this determination 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 3.2 acres of sandy marine habitat potentially utilized by various life stages of corals (all life stages), shrimp (all life stages), reef fish (all life stages), coastal migratory pelagics (all life stages), red drum (all life stages), Atlantic sharpnose shark (Gulf of Mexico Stock; juvenile and adult), blacknose shark (Gulf of Mexico Stock; all life stages), nurse shark (juvenile and adult), bonnethead shark (Gulf of Mexico stock; all life stages) bull shark (juvenile and adult), blacktip shark (Gulf of Mexico Stock; all life stages), sandbar shark (adult), tiger shark (all life stages), spinner shark (neonate), and lemon shark (adult). Our initial determination is that the proposed action would not have a substantial adverse impact on EFH or Federally managed fisheries in the Gulf of Mexico. 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.
