WATERWAY AND LOCATION: The project would affect aquatic resources associated with the Atlantic Ocean. The project site is located at approximately 3.5 nautical miles at 30° from Government Cut Marker R “12” and approximately 1.4 nautical miles due east of the City of Miami Beach. The site dimensions requested for reauthorization are a nonstandard shaped polygon that is 1,500 yards long north-south by 800 yards east-west at the widest part. Depths at this site range from 40 feet to 60 feet with a minimum vertical clearance of -25 feet; in Miami-Dade County, Florida.
Corner points (Latitude (N) and Longitude (W)) for the boundaries of Anchorage Artificial Reef Site in decimal minutes (DM) and decimal degrees (DD) are provided in the table below.
EXISTING CONDITIONS: The project site is located at approximately 3.5 nautical miles at 30° from Government Cut Marker R “12” and approximately 1.4 nautical miles due east of the City of Miami Beach. The site dimensions requested for reauthorization are a nonstandard shaped polygon that is 1,500 yards long north-south by 800 yards east-west at the widest part. The total footprint of the Anchorage Artificial Reef site is 200.4 acres. Currently, artificial reefs have only been placed on approximately 0.16 acres. Over the course of a 10-year permit, new artificial reef construction is expected to occur on approximately 1.5 acres. Artificial reef deployments will occur a minimum of 200 feet from the emergent biota resources on sandy barren habitat.
The federal permitting history includes an ongoing permit authorization since May 02, 2003, for the proposed activities that includes construction for ten (10) years within the previously permitted 200.4 acres Anchorage artificial reef area; specifically, to strategically deploy and/or anchor approved artificial reef material (as acquired) into the existing artificial reef site.
PROJECT PURPOSE:
Basic: The basic project purpose is the nourishment/renourishment of an existing artificial reef for marine habitat enhancement.
Overall: The overall project purpose is the nourishment/renourishment of an existing artificial reef for marine habitat enhancement, offshore mainland Miami-Dade County, Florida through artificial reef habitat placement on barren sandy substrate.
PROPOSED WORK: The applicant seeks reauthorization to create artificial reef by deploying approximately 300 cubic yards of calcium-carbonate based, such as limestone boulders, prefabricated artificial reef modules, or large concrete-based materials (i.e., connection/junction boxes, large sections of bridge decking or other construction demolition) material annually or 3,000 cubic yards (0.5 acres /21,780 square feet) over the life of a 10-year permit.
AVOIDANCE AND MINIMIZATION: The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:
At the POM A Artificial Reef Site, only natural or calcium-carbonate based materials will be deployed such as limestone boulders, prefabricated artificial reef modules, or large concrete-based materials such as connection/junction boxes, large sections of bridge decking or other construction demolition. Vessels or barges will not be deployed at this site.
All artificial reef material deployments will be prepared as necessary to meet permit conditions and follow guidelines set forth in the following best management practice (BMP) documents:
Guidelines for Marine Artificial Reef Materials 2nd Edition (Association of the Gulf and Atlantic States Marine Fisheries Commissions 2004)
National Artificial Reef Plan: Guidelines for Siting, Construction, Development, and Assessment of Artificial Reefs (NOAA 2007)
Guidelines and Management Practices for Artificial Reef Siting, Usage, Construction, and Anchoring in Southeast Florida (Southeast Florida Coral Reef Initiative, Lindberg and Seaman (editors), 2010)
All artificial reef deployments will be evaluated based on specific characteristics of a 25-year storm event to provide the necessary safeguard against material movement consistent with current permit. The Lin Stability model distributed by the Florida Fish and Wildlife Conservation Commission (FWCC) and the Miami-Dade stability model developed by Coastal Systems International will be utilized to assess the stability of each individual artificial reef prior to deployment. If a proposed artificial reef is not indicated to be stable at the site depth, the material will not be deployed.
Artificial reef deployments will avoid areas with known benthic resources based on Laser Airborne Depth Sounder (LADS) data from 2003, NOAA side scan data from 2009, benthic habitat maps (Walker 20091), and the assessment by DERM Biologists in the fall of 2024. All deployments will maintain a 200 ft buffer to known natural resources consistent with previous permit conditions.
A biological survey will also be conducted immediately prior to the deployment of any materials. Biological surveys will be conducted by DERM marine biologists using SCUBA. Each survey will initially consist of the placement of a temporary marker buoy at the proposed target reef location. Divers will then conduct a survey for any resources within a 200 ft minimum radius of the marker buoy. If benthic resources such as hardbottom or seagrass are found during this survey, the target position will be altered to provide appropriate buffer distance from resources. If adequate buffer distances are not available, the initial target site will be abandoned, and another location evaluated.
Reef materials will be transported to the site via tugboat and/or barge. On site, the vessel transporting the materials will be positioned directly adjacent to the previously established buoy, and held in position either by anchoring/spudding, with dynamic positioning using tugboat(s), or combination of tugs and anchors. Once a stable configuration at the target buoy is achieved the material will be deployed. Concrete and boulder materials will be offloaded using heavy equipment such as cranes or loaders.
In water surveys will also be conducted immediately post deployment to verify that material was deployed where intended and does not exceed navigational clearance requirements. Adjustments to location or material height off the substrate are made if necessary. The dimensions and relief of the new artificial reef area are measured and, if the size of the reef allows, the perimeter is traced by divers towing a surface GPS unit. This information will be incorporated into a material placement report and submitted to the Florida Fish and Wildlife Conservation Commission.
COMPENSATORY MITIGATION: The applicant has provided the following explanation why compensatory mitigation should not be required:
A compensatory mitigation plan has not been submitted as unavoidable functional loss to the aquatic environment is not being proposed. All artificial reef deployments will occur on barren, sandy substrate a minimum of 200 feet from benthic resources based on the Benthic Resource Report and in accordance with the avoidance and minimization methodology plan. Should any unplanned impacts occur, Miami-Dade County will contact the Army Corps Engineers and other environmental permitting agencies to develop a specific mitigation plan.
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, federally recognized tribes and other interested parties.
ENDANGERED SPECIES: The Corps has performed an initial review of the application, the National Marine Fisheries Service (NMFS) Section 7 Mapper, and the NMFS Critical Habitat Mapper to determine if any threatened, endangered, proposed, or candidate species, as well as the proposed and final designated critical habitat may occur in the vicinity of the proposed project. Based on this initial review, the Corps has made a preliminary determination that the proposed project may affect species and critical habitat listed below. No other ESA-listed species or critical habitat will be affected by the proposed action.
