Expiration date: 2/24/2022
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: Mr. Rafael Machargo
Secretary, Department of Natural and Environmental Resources
San José Industrial Park
1376 Ave. Ponce de León
San Juan, Puerto Rico 00926

WATERWAY AND LOCATION: The project would affect waters of the United States associated with Caribbean Sea. The project sites (5) are located at East of Palominos Island near of Bajo Blake within the Arrecifes de la Cordillera Natural Reserve, Municipality of Fajardo, Puerto Rico.

Directions to the site are as follows: From San Juan take the Baldorioty de Castro Avenue to Carolina, exit at expressway PR-66 to Fajardo, turn right at State Road PR-3, turn left at road PR-194 and turn left at road PR-195 toward the old Fajardo’s Ferry Ports Terminal. The project sites are located to East side of Palominos Island, at the east coast of Puerto Rico, near the coast of Fajardo. The accessibility is only by boat.


Site 1 (CP.1): Latitude: 18.34370° Longitude: -65.54550°

Site 2 (CP.2): Latitude: 18.34615° Longitude: -65.54653°

Site 3 (CP.3): Latitude: 18.34075° Longitude: -65.54141°

Site 4 (CP.4): Latitude: 18.34206° Longitude: -65.54073°

Site 5 (CP.5): Latitude: 18.34287° Longitude: -65.54230°


Basic: Artificial Reefs Modules.

Overall: To enhance rugosity of the sea bottom, production and aggregation of sport fish species, and increase settlement of coral larvae and other marine biota.

EXISTING CONDITIONS: The proposed sites are located within the Arrecifes de la Cordillera Natural Reserve. Based on the results of the benthic study, the type of substrate that dominates the seabed across the proposed five sites is mostly 100% sandy. The existing depths range at the project sites is from 65 feet to 75 feet. Near the selected sites, between Palominos Island and Bajo Blake, the applicant has already installed in two areas approximately 50 artificial reefs on a sandy bottom at a depth of 60 feet. These existing artificial reef complexes named “Blake 1 (Manhole AR) and Blake 2 (Reef Ball)” are located in the 18 20.421N -65 32.389W and 18 20.225N -65 32.347W coordinates (central point of the project), respectively and each overs an approximate area of 900 square meters. In nautical chart number 25663 of NOAA (Passage of San Juan to Puerto of Humacao and western part of Isla de Vieques), a polygon is identified as an area with existing artificial reefs and named "Obstn Fish Haven".

PROPOSED WORK: The applicant seeks authorization to deploy a total of five (500) hundred artificial reef (ARs) structures to be located in five different sites on a sandy sea floor in navigable waters of the United States. The five sites are located at a distance of approximately 500 feet or more from each one. Each proposed site will contain 100 artificial reefs modules or units in five AR groups composed by a clearance and boundary square-shaped zones measuring each 70m x 70m. Each of the five AR groups will have four groups at the corners with 4 artificial reefs modules or units in each corner, and one group in the center, with 4 artificial reefs modules or units. The set of 4 artificial reefs units or modules will cover an area of 225 square meters or 0.054 acres of the maritime bottom. Each of the five groups will be formed with a total of 20 prefabricated AR units or modules, resulting in 100 artificial reefs modules per site. Approximately 4 meters will be left between each unit of artificial structure. The area of maritime bottom to be covered by the artificial reefs modules or units for each site is approximately 1.36 acres. The total volume in cubic yards for each artificial reef is 1.37 yd3 for Pyramid reef, 1.15 yd3 for Manhole reef, 0.54 yd3 for Layer cake reef and 1.80 yd3 for Modified block. The total volume of all five hundred (500) artificial reefs is 607.50 yd3 . The distance from the top of these structures to the water surface (or the authorized minimum clearance) is 58.5 ft for areas with 65 ft depth and 68.5 ft for areas with 75 ft depth. Each unit of artificial reef structures will be anchored to the sandy sea bottom using Helix brand, helix Jr. type anchors.

These artificial reefs modules will consist of a non-polluting and durable low pH and 5,000 psi with micro silica concrete layers, constructed to ensure that they will remain intact for many years submerged in a marine environment. The AR unit shall be massive with sufficient weight (approximately from 4,000 to 7,000 lbs.) to withstand storms, current surges without lateral displacement. Also, AR unit shall be designed for minimal bearing pressure on the seabed to minimize sinking in soft mud and will have a rough texture to enhance marine growth. The pyramid module will have an open top of 36 inches and measures: 2.36 m long x 1.83 m tall x 2.36 m wide; the manhole module will have a hole at the top of 39.3-inches and measures 1.37 m long x 1.37 m tall x 1.37 m wide; the layers cake module measures 0.91 m base diameter x 1.98 m tall, and the modified block measures 2.13 m long x 1.68 m tall x 2.13 m wide, and its base is formed and supported by two (2) side walls and two (2) open walls in which these open sides are 0.61 meter in height and 1.22 meter long with an entrance and an exit. A second story of the same structure is added to the top, which provides a complex reef for habitat and protection for juveniles and other animals. Also, using limestone rocks attached to the layers will provide space for coral larvae to settle. The holes (pyramid module and manhole module) allow sea turtles to escape or exit easily. Each structure design is planned to be safe for any marine life and allows water flow as well space for fish and marine life to settle and travel through these modules. This project has a federal aid grant from the U.S. Fish and Wildlife Service.

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:

The artificial reefs structures will be constructed on land and transported to the shoreline of Fajardo where they will be placed on a barge for transportation to the project site. These structures will be placed always on seabed and will not be thrown from the surface to prevent its fall into another area. If there is a need to relocate any of the structures, compressed air lifting bags will be used to float the unit to avoid dragging of the structures on the seabed and preventing unwanted movement of sediments in the water column.

COMPENSATORY MITIGATION – The applicant has offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:

The applicant has provided the following explanation why compensatory mitigation should not be required: Due to the nature of the project, which is to provide new maritime habitat that enhance the aggregation and production patterns of marine fishes.
