TO WHOM IT MAY CONCERN: This supersedes the Public Notice issued on August 11, 2023. 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: Antonio L. Ortiz
Reefscaping HJR
P.O. Box 1553
Boqueron, PR 00622
WATERWAY AND LOCATION: The project would affect waters of the United States associated with the Atlantic Ocean. The project sites are located at Rompe Olas Beach, Municipality of Aguadilla, Puerto Rico.
Directions to the site are as follows: The project sites will be located to northwest coast of P.R. near the coast of Aguadilla. From San Juan take the express way PR 22 to Hatillo and at the end, exit at PR-2 to Aguadilla. Turn right at PR-2R (Av. San Carlos) and turn right at PR-111 toward the Aguadilla Rompe Olas. The accessibility is by boat or swimming from the Rompe Olas or from the beach using fins, mask, and snorkel when sea conditions allow it.
APPROXIMATE CENTRAL COORDINATES:
Zone A: Latitude: 18.438029º Longitude: -67.158031
Zone B: Latitude: 18.435596º Longitude: -67.158324
PROJECT PURPOSE:
Basic: Artificial Reefs Burials.
Overall: To enhance marine biodiversity, support ecological restoration efforts, and contribute to sustainable coastal management by implementing an artificial coral reef burial.
EXISTING CONDITIONS: According to a benthic study conducted by HJR Reefscaping, the study area and the proposed footprint is dominated by large extensions of fine unconsolidated sediments and sand with invertebrates. This habitat consisting of fine sediment substratum was colonized by patches of cyanobacteria. The benthic surveys of the hard ground areas of exposed rocky surfaces had higher biological diversity in shallower (7-10-feet) areas adjacent to the coastline. In the areas where the placement of the reef modules is proposed the predominant habitat is 96% sand unconsolidated sediment. No coral or fish species designated as Threatened under the Endangered Species Act were present in the footprint area surveyed. This can be partially explained by a lack of suitable hard substratum for colonization. Corals designated as Threatened were present on shallower hard ground located at a distance of more than 65-feet from the proposed project’s footprint.
PROPOSED WORK: The applicant seeks authorization for the installation of 220 artificial reef structures (17.76 square feet each; 3,907.2 square feet total). The modules are made of Portland cement, silicate sand, limestone gravel, and source silica (from crushed bottles to reduce pH), with added ash remains, molded on a reinforced steel frame. Each module measures 3.6 feet wide, 4.9 feet long, and 3.6 feet high, supports 3,000 psi, and weighs 1,100 to 1,200 pounds. The depth in the deployment area ranges from 20 to 22 feet, with all artificial reefs deployed over a sandy sea floor 32 to 82 feet from nearby habitats classified as consolidated pavement with scattered corals, sponges, and gorgonians. This project aims to create the first marine burial project in Puerto Rico, incorporating the remains of deceased relatives while providing habitat for coral reef creatures.
This would be developed in a series of phases over three years along two trails in the event if the proposed Pilot Study is approved. This would be as followed:
Phase 1: Pilot Study
Activities:
Install 6 structures:
Three in Zone A (positions 1, 8, and 16).
Three in Zone B (positions 22, 30, and 38) (see Table 1 and Figure 1).
Monitoring Plan:
Evaluate structures every four months.
Monitor the following variables:
Recruitment of macro invertebrates: Observe corals and other organisms colonizing the structures.
Sedimentation rate: Use sediment traps to collect and dry sediments, determine volume, and weigh (grams) to estimate sedimentation rate.
Stability of the structures: Measure height from the sandy bottom to the top of the structures to check for sediment coverage, tilting, or displacement. Assess structure permanence in place against tides or atmospheric phenomena.
Approval:
Obtain approval of the Pilot Study before proceeding with subsequent phases.
Phase 2: First Year
Activities:
Install 32 additional modules along Zone A and Zone B trails.
Ensure modules are 10 feet apart.

Material composition: Portland cement, silicate sand, gravel, ash remains, and reinforced steel frame.
Supports up to 3,000 psi.
Phase 3: Second Year
Activities:
Install 72 additional modules.
Modules to be placed 10 feet from the existing structures.
Coverage:
Total area: 305 square feet (0.007 acres).
Structure Details:
Same as Phase 1.
Phase 4: Third Year
Activities:
Install 110 additional modules.
Placement parallel to the coral trail.
Coverage:
Total area: 436 square feet (0.010 acres).
Structure Details:
Same as Phase 1.
Detailed information on locations of proposed modules are enclosed.
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 structure will be constructed on land and transported to the shoreline of Aguadilla where they will be floating using air lifting bags and transported using small vessel to the project site. Once on site it will be slowly place on seabed and anchored to the sand seafloor using Helix JR. Mooring Anchor from Helix Mooring Systems, Inc. All marine activities will take care of nearby marine organism as recommended by the DRNA (we will include a marine observed in our staff).”
COMPENSATORY MITIGATION – 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.”
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.
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. Informal Consultation with US Fish and Wildlife Service (USFWS) was initiated on July 7, 2023. USFWS concurred with the Corps determination on July 18, 2023.
The Corps will evaluate the proposed work utilizing NMFS’s Jacksonville District’s Programmatic Biological Opinion (JAXBO) dated November 20, 2017. The JAXBO analyzes the effects from 10 categories of minor in-water activities occurring in Florida and the U.S. Caribbean on sea turtles (loggerhead, leatherback, Kemp's ridley, hawksbill, and green); smalltooth sawfish; Nassau grouper; scalloped hammerhead shark, Johnson's seagrass; sturgeon (Gulf, shortnose, and Atlantic); corals (elkhorn, staghorn, boulder star, mountainous star, lobed star, rough cactus, and pillar); whales (North Atlantic right whale, sei, blue, fin, and sperm); and designated critical habitat for Johnson's seagrass; smalltooth sawfish; sturgeon (Gulf and Atlantic); sea turtles (green, hawksbill, leatherback, loggerhead); Giant manta ray; North Atlantic right whale; and elkhorn and staghorn corals in accordance with Section 7 of the Endangered Species Act. Based on past permitting practices of the Corps and review of consultations with similar in-water construction activities, Project Design Criteria (PDCs) were identified in the JAXBO that typically have been applied to permitted in-water construction activities. These PDCs ensure effects of in-water construction activities are minimal in nature and do not result in adverse effects to listed species or to essential features of designated CH. Furthermore, the Corps has determined that the project would have “no effect” on the Queen conch (Strombus gigas). The applicant will be required to perform survey before placing modules to ensure that no queen conch, or other marine resource will be impacted during the operation. If queen conch is identified by survey prior to deployment, the project applicants will wait until the queen conch exit the area. For this verification, the Corps conducted a project specific review to ensure that all of the PDCs were met. Therefore, the Jacksonville District satisfied the project-specific review requirements stipulated in the JAXBO and satisfied its obligation under the ESA for the above-listed species and critical habitats within the NMFS purview.
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. Our initial determination is that the proposed action would not have a substantial adverse impact on EFH or Federally managed fisheries in Atlantic Ocean. 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 activity 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.
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.
