Basic:  Reef Habitat Enhancement


Overall:  To provide additional deepwater reef habitat to enhance existing and create new coral and fish habitat within the Ernst Reef deployment area, Martin County, Florida.


PROJECT HISTORY:  The Corps issued a permit for three artificial reef sites: Donaldson Reef, Ernst Reef, and Sirotkin Reef by standard permit SAJ-1995-04128 dated June 22, 1995. The permit was extended and expired on June 30, 2001. The Corps issued a modification on January 11, 2001. The Corps modified the permit on February 7, 2006 to extend the expiration date for all three reef locations to February 7, 2011. The permit was modified on December 15, 2009 to exclude monitoring of reefs in depths greater than 100 feet and instead only conduct fathometer surveys to document the locations. The Corps issued a standard permit (SAJ-1995-04128) for the reauthorization of ratification reef materials on January 14, 2011 and July 26, 2016 for all three reef locations. The most recently issued standard permit will expire on July 26, 2021.  


The applicant has requested a reauthorization for the deployment of materials within the same footprint.  Each of the artificial reef deployment areas have been assigned a separate SAJ number in the most recent application.  The following SAJ numbers have been assigned to the three deployment areas as follow and will be coordinated under separate Public Notices:


Deployment Area

SAJ Number

Donaldson Reef


Sirotkin Reef (east and west)


Ernst Reef





EXISTING CONDITIONS: The Ernst Artificial Reef Deployment Area is roughly 288 acres in size.  The benthic habitat within the boundaries consist of predominately unconsolidated sand substrate separated by bands of hardbottom and coral benthic habitats. The Ernst artificial reef deployment area ranges in depths from 60 to 80 feet mean low water (MLW).  A variety of reef materials have been deployed, since the issuance of the 1995 permit within the boundaries to create high and low profile reefs as shown in Figure 1.  Deployed materials include concrete and steel scrap, bridge rubble, concrete reef modules, limestone rock, and sunken steel vessels.  The previously authorized minimum clearance was 50 feet.


Figure 1. Table showing the locations and information about deployments within the Ernst Artificial Reef Deployment Area


PROPOSED WORK:  The applicant seeks re-authorization to deploy a variety of artificial reef materials within the Ernst Reef Deployment Area (total of 288 acres) for a period of ten years.  Material may include concrete, limestone boulders, submerged vessels, and other approved marine substrate.  Material placement will occur in areas devoid of hardbottom habitat and other benthic resources.  The top of the reef material shall maintain a minimum vertical clearance of 50 feet and twice the height of the structure from the top of the deployed material relative to the MLW at all times.


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:


Prior to all deployments and pre-construction survey of the reef placement area will be conducted to ensure there are no hardbottom resources present within the deployment site, or within a 50-foot buffer area around the site.  If such resources are found, the deployment target will be relocated away from those resources, into an area that meets the criteria.

Reef structures, materials, and installation methods shall be designed and deployed to prevent entanglement and entrapment of listed species.

Reef materials or modules will weigh more than 500 pounds. Reef materials shall be clean and free from asphalt, creosote, petroleum, other hydrocarbons and toxic residues, loose free-floating material or other deleterious substances. All artificial reef materials and/or structures will be selected, designed, constructed, and deployed to create stable and durable marine habitat.

Applicant agrees to adhere to the Comply with JAXBO PDC’s for In-Water Activities, and the PDCs listed in Activity 7

Comply with the Standard Manatee Conditions for In-Water Work – 2011

All deployments will be conducted during daylight hours


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


The benthic substrate within the Ernst Reef Deployment Area is all sand and no adverse impacts to hardbottom habitat, corals or seagrass are anticipated, therefore no mitigation should be required.


CULTURAL RESOURCES:  The Corps is not aware of any known historic properties within the permit area.  By copy of this public notice, the Corps is providing information for review.  Our final determination relative to historic resource impacts is subject to review by and coordination with the State Historic Preservation Officer and those federally recognized tribes with concerns in Florida and the Permit Area.


ENDANGERED SPECIES:  The Corps has determined the proposed project may affect, but is not likely to adversely affect the West Indian Manatee (Trichechus manatus); Swimming sea turtles: (green sea turtle (Chelonia mydas), Kemp’s Ridley sea turtle (Lepidochelys kempii), Leatherback sea turtle (Dermochelys coriacea), Hawksbill sea turtle (Eretmochelys imbricata), and Loggerhead sea turtle (Caretta caretta)); smalltooth sawfish (Pristis pectinata); Loggerhead constricted migratory critical habitat; and Northern right whale (Eubalaena glacialis). The Corps will request U.S. Fish and Wildlife/National Marine Fisheries Service concurrence with this determination pursuant to Section 7 of the Endangered Species Act. 


The Corps has determined the proposal would have no effect on any other listed threatened or endangered species or designated critical habitat.


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 288 acres of sandy substrate separated utilized by various life stages of penaeid shrimp complex, reef fish, stone crab, spiny lobster, migratory/pelagic fish, and snapper/grouper complex.  Our initial determination is that the proposed action would not have a substantial adverse impact on EFH or Federally managed fisheries in the South Atlantic Region.  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.


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 been verified by Corps personnel.


AUTHORIZATION FROM OTHER AGENCIES:  Water Quality Certification may be required from the Florida Department of Environmental Protection and/or one of the state Water Management Districts.


COMMENTS regarding the potential authorization of the work proposed should be submitted in writing to the attention of the District Engineer through the Palm Beach Gardens Permits Section, 4400 PGA Boulevard, Suite 500, Palm Beach Gardens, Florida, 33410 within 30 days from the date of this notice.


The decision whether to issue or deny this permit application will be based on the information received from this public notice and the evaluation of the probable impact to the associated wetlands.  This is based on an analysis of the applicant's avoidance and minimization efforts for the project, as well as the compensatory mitigation proposed.
