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 404 of the Clean Water Act (33 U.S.C. §1344) and Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. §403) as described below:
APPLICANT: R Duncan Matthewson, PO Box 430301, Big Pine Key, FL, 33043
WATERWAY AND LOCATION: The project would affect aquatic resources associated with Florida Bay. The project site is located at 28505 Jolly Roger Drive, in Section 28, Township 66 South, Range 29 East, Little Torch Key, Monroe County, FL, 33042. RE#00218050-000000.
APPROXIMATE CENTRAL COORDINATES: Latitude 24.654755°N
Longitude -81.386472° W
PROJECT PURPOSE:
Basic: The basic project purpose is to provide shoreline stabilization, provide vessel mooring, and allow for launching/removal of the vessel.
Overall: The overall project purpose is to provide shoreline stabilization, provide vessel mooring, and allow for launching/removal of the vessel for a property owner in Little Torch Key, Monroe County, FL.
EXISTING CONDITIONS: The wetland system consists of a saltwater system. The onsite vegetation consists of mangroves and other wetland vegetation. The existing area surrounding the project area consists of developed lots. There are no corals or seagrass within the project boundaries.
PROPOSED WORK: The applicant seeks authorization to construct a 410 sf dock and a boat ramp (600 sf, with 50 cy of excavation). Additionally, 325 sf of riprap boulders will be placed beneath the dock. 495 sf of red mangroves will be impacted. 160 sf of mangroves will be avoided. Turbidity curtains will be deployed prior to construction and will remain in place until water quality returns to pre-construction conditions.
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 the start of construction, turbidity curtains will be deployed to isolate the construction site from ambient waters which will remain in place until all construction induced turbidity has subsided and water quality has returned to pre-construction conditions.
COMPENSATORY MITIGATION – The applicant has offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:
If required by the ACOE, the applicant shall make payments to the Keys Restoration Fund Program to offset unavoidable impacts to wetlands.
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 parcel is on the FEMA Monroe County List.
Lower Keys marsh rabbit (Sylvilagus palustris hefneri): Potential impacts to the LKMR were evaluated using the Lower Keys marsh rabbit (LKMR; Sylvilagus palustris hefneri) Species Key, dated 29 July 2013, and resulted in the following sequential determination: The project is not located on Big Pine Key or No Name Key. Use of the SAGs resulted in the following sequential determination: A > F (2), “may affect, not likely to adversely affect (NLAA)”. This determination is partially based on the applicant being provided the cat brochure. The Corps received programmatic concurrence from the FWS for projects that have a “NLAA determination; therefore, no incidental take will occur and no further consultation with the FWS is required.
Silver rice rat (Oryzomys palustris natator) Critical Habitat: Although the subject parcel is not located within the designated critical habitat, use of the Silver Rice Rat Critical Habitat Assessment Guide dated 29 July 2013, resulted in the following sequential determination A > E(2), “may affect, but not likely to adversely affect.” This determination is based on the applicant proposing no removal or modification of the rice rat’s native habitat. Based on the information provided above the Corps has reached a MANLAA determination on the silver rice rat’s designated critical habitat. The Corps received programmatic concurrence from the FWS for projects that have a NLAA determination; therefore, no incidental take will occur and no further consultation with the FWS is required.
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), the
smalltooth sawfish (Pristis pectinata) and its designated critical habitat: Sea turtles, Nassau grouper, and Smalltooth sawfish may be temporarily unable to use the site during construction: They may avoid the construction site, be affected by noise, and physically excluded from the project area. In-water construction machinery and pile installation may injure the species, though they will likely move away from the project site if disturbed; therefore, a MANLAA determination was reached for the sea turtles, Nassau grouper, and smalltooth sawfish species. The project is not located within loggerhead sea turtle or smalltooth sawfish critical habitat; therefore, a no effect determination was reach on their critical habitat. The Corps requested NMFS PRD concurrence with this determination in accordance with Section 7 of the Endangered Species Act.
West Indian Manatee (Trichechus manatus): Since the proposal by the applicant is for in-water construction, potential impacts to the endangered West Indian manatee were evaluated using Corps of Engineers, Jacksonville District, and the State of Florida Effect Determination Key for the Manatee in Florida, April 2013 (Key). Use of the Key resulted in the sequence : A > B > C > G > H > I > N > 0 > P (4), “may affect, not likely to adversely affect”, where no further consultation with the Service is necessary. This determination is based on the applicant following the standard Manatee construction conditions for the proposed activity, which are reiterated as special conditions of the permit.
Listed Corals: Acropora spp. (Acropora cervicornis and Acropora palmata), and
its designated critical habitat, and listed coral species: pillar coral (Dendrogyra
cylindrus), lobed star coral (Orbicella annularis), mountainous star coral
(Orbicella faveolata), boulder star coral (Orbicella franksi), rough cactus coral
(Mycetophyllia ferox): Listed corals are not located within the project area. Furthermore, the project is not located within Acropora sp. critical habitat; therefore, a no effect was reached on listed corals, Acropora species, and Acropora sp. critical habitat.
American crocodile (Crocodylus acutus): The project is located within American crocodile (Crocodylus acutus) consultation area. According to the 28 October 2014 American Crocodile Key, the property does not support suitable nesting habitat for the crocodile as the shoreline is densely vegetated and/or hardened. Use of the Key resulted in the sequence #2. Therefore, the Corps has reached a “may affect not likely to adversely affect” determination on the American crocodile and its suitable nesting habitat. No further consultation with the FWS is required for the American crocodile.
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. [INCLUDE IF APPROPRIATE] The proposal would impact approximately 1335 square feet of mangrove habitat and marine bottom utilized by various life stages of marine life. 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.
Navigation: The proposed structure 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.
