SAJ-1989-90053 (SP-LCK)

Published Nov. 10, 2020
Expiration date: 12/9/2020

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. §408) as described below:

APPLICANT: City of Delray Beach
Attn: Jennifer Alvarez
434 South Swinton Ave.
Delray Beach, FL 33444

WATERWAY AND LOCATION: The project is located along a 2.8 mile segment of Atlantic Ocean shoreline eastward of N. Ocean Boulevard, Delray Beach from FDEP Reference monuments R-175+330 to R-188A (Sections 9, 16, 21, and 28, Township 46 South, Range 43 East) Palm Beach County Florida.

Directions to the site are as follows: Exit I-95 at Woolbright Ave, Exit 56. Continue east on Woolbright Road Florida A1A, turn right on Florida A1A. Continue south for approximately 2.7 miles. The northern limit of the project area is located to the east at monument R-175+330.





Northern Beach limit (R-179+330)



Southern Beach limit (R-188A)



Borrow Area I















Borrow Area II















Borrow Area D-V















Borrow Area D-IV















Borrow Area D-III
















Basic: The basic project purpose is shoreline stabilization.

Overall: The overall project purpose is to stabilize the shoreline and address the adverse effects of past, and ongoing, shoreline erosion between FDEP monuments R-175+330 to R-188A.

EXISTING CONDITIONS: The project extends along the shoreline of the City of Delray Beach. The existing area surrounding the beach placement area consists of a dune system, S.R. A1A, and residential development to the east. The Atlantic shoreline within the project area is a beach that is constantly being shaped by the tides, winds, and waves. The beach and dune are essential nesting habitat for marine sea turtles. Aquatic resources within the project area include tidal and sub-tidal waters, intertidal and sub-tidal unconsolidated bottoms, and intertidal and sub-tidal hardbottom. Other habitats include dry beach and upland development. The marine habitat within the project area is composed of unconsolidated soft bottom habitat. No nearshore hardbottom is located within the project footprint. The nearest reef formation is a shore-parallel offshore reef track within 60-foot depth and located approximately 1,200 feet seaward of the nearest borrow area

Borrow Area I and II were previously dredged for the Fifth Periodic Beach Renourishment project. The two offshore borrow areas are located approximately 2,000 feet offshore. The borrow areas vary in width from 1,000 feet to 425 feet and have a combined length of 2.8 miles, which extends parallel to the beach.

A sand search was conducted in 2019, which resulted in the proposed expansion of the existing authorized Borrow Areas to the north, south, west, and deeper than the authorized borrow areas. The currently proposed borrow areas are Borrow Areas D-IV and D-V. Borrow Area D-V is a new borrow area and Borrow Area D-IV overlaps with the previously authorized Borrow Area II. These offshore borrow areas are located more than approximately 1,600 feet offshore. The borrow areas vary in width from 900 feet to 500 feet and have a combined length of 2.3 miles, which extend parallel to the beach.

PROJECT HISTORY: Delray Beach was initially nourished in 1973 to provide storm protection and recreational benefits to the city. Subsequent re-nourishments took place in 1978, 1984, 1992, 2002, 2005 (FCCE), and 2013, 2014 (FCCE), and 2020 (FCCE). Beginning with the beach nourishment conducted in 1992, the design interval between beach nourishments was increased to eight years. The existing Corps permit SAJ-1989-90053 expires on June 18, 2022. The reason for the reauthorization is to reconstruct the federally authorized design section and advance nourishment that was placed in 2013 for the Fifth Periodic Beach Re-nourishment project and the 2014 Flood Control Coastal Emergency (FCCE) project. The proposed project is the sixth periodic re-nourishment of Delray Beach.

PROPOSED WORK: The applicant proposes the re-nourishment of the federally authorized beach template that will place approximately 1,057,000 cy of beach compatible material along an approximately 2.8 mile segment of beach between R-175+330 to R-188A. Approximately 505,000 cubic yards would be placed at, or below the mean high water (MHW) line and the remaining 552,000 cubic yards placed at or above MHW to partially restore the supra-tidal beach. The design cross section provides for a berm width extension of 100 feet (30.5 m) from the Erosion Control Line (ECL) at an elevation of +7.5 feet (2.29 m) NAVD, and a seaward slope of 1V:10H. The sand will be dredged from Borrow Areas D-V and D-IV with a cutterhead or hopper dredge. The material will be transported from the offshore borrow site to the beach placement site through a series of submerged, floating, and shore-supported pipelines.

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: There is no direct or indirect impacts to hardbottom habitat proposed or anticipated, as reef resources are located more than 3,400 feet waterward of the fill template and approximately 1,100 feet from the existing and proposed borrow areas. The proposed borrow areas are located more than 1,300 feet offshore of the project, seaward of the -32 ft contour. During construction the project would require the implementation of sediment barriers to ensure water quality, including construction of berms or dikes; the use of a turbidity mixing zone in accordance with the 401 water quality certification if required by the Florida Department of Environmental Protection (FDEP); and downstream turbidity monitoring to ensure compliance with turbidity standards. Compliance with turbidity monitoring requirements will ensure turbidity levels remain within permitted limits.

COMPENSATORY MITIGATION: The applicant has stated the following: The proposed project does not directly or indirectly impact any hardbottom or coral habitat, therefore no compensatory mitigation is proposed or required.

CULTURAL RESOURCES: 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 proposal may affect the threatened and endangered nesting sea turtles (Chelonia mydas, Eretmochelys imbricata, Lepidochelys kempii, Dermochelys coriacea, Caretta caretta, Lepidochelys olivacea), threatened West Indian manatee (Trichechus manatus), and the Loggerhead designated terrestrial critical habitat Unit LOGG-T-FL-13. The Corps also determined the proposed project may affect but is unlikely to adversely affect the threatened piping plover (Charadrius melodus). The Corps has determined that the project is consistent with the Statewide Programmatic Biological Opinion (2015-SPBO, Service 2015), and the Programmatic Piping Plover Biological Opinion (P3BO, Service 2013). 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 project may affect the threatened swimming sea turtles (Chelonia mydas, Eretmochelys imbricata, Lepidochelys kempii, Dermochelys coriacea, Caretta caretta, Lepidochelys olivacea), and may affect but is unlikely to adversely affect the loggerhead (C. caretta) designated migratory, breeding and reproductive critical habitats. The Corps has determined the project may affect but is unlikely to adversely affect the smalltooth sawfish (Pristis pectinata). The Corps will request review of the proposed project for compliance with the 2020 National Marine Fisheries Service (NMFS) South Atlantic Biological Opinion (SARBO). If required, the Corps will request initiation of formal consultation with NMFS pursuant to Section 7 of the Endangered Species Act by separate letter.

ESSENTIAL FISH HABITAT: 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 project is anticipated to directly or indirectly affect 73.1 acres of nearshore unconsolidated sandy benthic habitat that is utilized by various life stages of penaeid shrimp complex, red drum, reef fish, stone crab, spiny lobster, migratory/pelagic fish, and snapper/grouper complex. There is no nearshore hardbottom within the project area. Dredging offshore shoal areas consisting of sand, shell and rock may also affect managed species. The offshore reef is located approximately 1,100 feet waterward of the borrow areas at the closest point. 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.
