Published Sept. 19, 2019
Expiration date: 10/10/2019
TO WHOM IT MAY CONCERN: The Jacksonville District of the U.S. Army Corps of Engineers (Corps) has received an application for a Department of the Army permit pursuant to Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. §403) as described below:

APPLICANT: Village of Islamorada
C/o Seth Lawless
86800 Overseas Highway
Islamorada, Florida 33036

WATERWAY AND LOCATION: The project would affect waters of the United States associated with the Florida Bay. The project is located along Canal #152 located between Gulfview Drive and Venetian Drive within the Village of Islamorada, Monroe County, Florida.

Directions to the site are as follows: Take U.S. 1 South to MM74; Turn right onto Gulfview Drive; Project is located along Canal #152 located between Gulfview Drive and Venetian Drive.

APPROXIMATE CENTRAL COORDINATES:
Latitude: 24.859266
Longitude: -80.733312

PROJECT PURPOSE:

Basic: Maintenance dredge to restore water depths in navigable waters of the United States.

Overall: Maintenance dredge to restore water depths in navigable waters of the United States in the Village of Islamorada, Florida.

EXISTING CONDITIONS: The canal system consists of a saltwater system. The project is located within a developed residential subdivision tributary to the Florida Bay. The canal was impacted by Hurricane Irma creating pockets of accumulated sediment throughout the canal systems. The subject canal system does have areas that support mangrove shorelines and potentially wetland lots; however, the agent has attested that no impacts to mangroves are proposed. In addition, the agent has indicated that the dewatering sites and disposal areas will be located within upland areas.

PROPOSED WORK: The applicant seeks authorization to maintenance dredge a total of 5,636.22 cubic yards of sediment accumulated post Hurricane Irma within a 304,355.81 square foot area to restore water depths to pre-Hurricane Irma conditions and to install temporary floating turbidity barriers around all work areas that are in/over navigable waters of the United States. Material will be dredged utilizing a hydraulic vacuum dredge or mechanical clam shell to remove the sediment accumulation depending on the composition of the material. The utilization of either system will result in the collection of a slurry from the canal bottom comprised of sediment and saltwater. The vessel based dredge excavates and places the material in a dedicated dewatering area. The contractor will either use a mechanical or passive dewatering system to handle the dredged material. The dewatering system will be located in an upland staging area adjacent to the canal. Once dewatered, the material will be transported to an approved upland disposal location dependent on the chemical characteristics of the material.

COMPENSATORY MITIGATION – The applicant/agent has provided the following explanation why compensatory mitigation should not be required: No impacts to corals, seagrass, mangroves, or hard bottom communities are proposed as the activity is limited to canal systems affected by Hurricane Irma; therefore, no migration is proposed.

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 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) or its designated critical habitat. Since the proposal by the applicant is for in-water construction, potential impacts to the endangered manatee were evaluated using The Corps of Engineers, Jacksonville District, and the State of Florida Effect Determination Key for the Manatee in Florida (Manatee Key), dated April 2013. Use of the Manatee Key resulted in the following sequential determination: A > B > C > G > N > O > P4 “may affect, but is not likely to adversely affect.” The Corps will request initiation of formal consultation with the Fish and Wildlife Service pursuant to Section 7 of the Endangered Species Act by separate letter.

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), hawksbill sea turtles (Eretmochelys imbricata), Kemp’s ridley sea turtles (Lepidochelys kempii), leatherback sea turtles (Dermochelys coriacea), the smalltooth sawfish (Pristis pectinata) and Acropora sp. critical habitat. The Corps has reached a no effect determination on Acropora sp. and corals species; (Dendrogyra cylindrus, Orbicella annularis, Orbicella faveolata, Orbicella franksi, Mycetophyllia ferox). The Corps will request National Marine Fisheries Service’s 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 304,355.81 square foot area of submerged bottom utilized by various life stages of marine life. The Corps has not independently verified if wetlands and/or submerged aquatic resources area located within the project footprint. 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.

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 and confirmation of resources located within the project footprint has not been verified by Corps personnel. Site inspections will be conducted by the Corps and/or benthic surveys will be required to document existing site conditions within the project footprint prior to reaching a final decision on the project.

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 Miami Permits Section, 9900 SW 107th Avenue, Suite 203, Miami, Florida 33176 within 21 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.

QUESTIONS concerning this application should be directed to the project manager, Maria Bezanilla, in writing at the Miami Permits Section, 9900 SW 107th Avenue, Suite 203, Miami, Florida 33176, by electronic mail at Maria.I.Bezanilla@usace.army.mil, by fax at (305) 526-7184, or by telephone at (305) 779-6057.

IMPACT ON NATURAL RESOURCES: Coordination with U.S. Fish and Wildlife Service, Environmental Protection Agency (EPA), the National Marine Fisheries Services, and other Federal, State, and local agencies, environmental groups, and concerned citizens generally yields pertinent environmental information that is instrumental in determining the impact the proposed action will have on the natural resources of the area.

EVALUATION: The decision whether to issue a permit will be based on an evaluation of the probable impact including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefits, which reasonably may be expected to accrue from the proposal, must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered including cumulative impacts thereof; among these are conservation, economics, esthetics, general environmental concerns, wetlands, historical properties, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food, and fiber production, mineral needs, considerations of property ownership, and in general, the needs and welfare of the people. Evaluation of the impact of the activity on the public interest will also include application of the guidelines promulgated by the Administrator, EPA, under authority of Section 404(b) of the Clean Water Act or the criteria established under authority of Section 102(a) of the Marine Protection Research and Sanctuaries Act of 1972. A permit will be granted unless its issuance is found to be contrary to the public interest.

The US Army Corps of Engineers (Corps) is soliciting comments from the public; Federal, State, and local agencies and officials; Indian Tribes; and other Interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps to determine whether to issue, modify, condition, or deny a permit for this proposal. To make this determination, comments are used to assess impacts to endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.

COASTAL ZONE MANAGEMENT CONSISTENCY: In Florida, the State approval constitutes compliance with the approved Coastal Zone Management Plan. In Puerto Rico, a Coastal Zone Management Consistency Concurrence is required from the Puerto Rico Planning Board. In the Virgin Islands, the Department of Planning and Natural Resources permit constitutes compliance with the Coastal Zone Management Plan.

REQUEST FOR PUBLIC HEARING: Any person may request a public hearing. The request must be submitted in writing to the District Engineer within the designated comment period of the notice and must state the specific reasons for requesting the public hearing.
