PROJECT PURPOSE:
Basic: Breakwater and enhancement of maritime habitats.
Overall: To mitigate dangerous rip currents at Condado sector and induce waves to break offshore in order to provide a safe beach for swimmers and users of this sector; to protect the beach from coastal erosion; and to provide ecological habitats for recreational and educational opportunities.
EXISTING CONDITIONS: The maritime bottom where the three submerged rubble mound structures in the Atlantic Ocean are proposed consists mostly of sandy substrate. Variable depths are at the project site from approximately -5 meters
(-16 feet) to -7 meters (-22 feet). The sea at Condado Beach sector has rough surf with rip-currents. Hard bottom habitat associated with a low relief patch reef exists at the western and south half section of proposed structures. Benthic algae colonizes most of the flat section of the patch reef in accordance to Reconnaissance Survey of Benthic Habitats conducted for beach front of La Concha Hotel in Condado dated June 24, 2018. Small and isolated colonies of live corals are present in the reef hard ground. No listed corals were reported at the proposed project’s footprint neither adjacent areas.
PROPOSED WORK: The applicant seeks authorization to build three submerged rubble mound structures in the Atlantic Ocean with these dimensions:

The proposed structures consists of two layers of armor stone over the under layer stone. The core of the structure segments will consist of conventional granite rock and the perimeter and toe will consist of a reef-like or karst stone. The total approximate volume of rock to be placed in waters of the U.S. is approximately 51,945 cubic meters. The source for fill material would come from quarries at the Municipalities of Guaynabo or Bayamón and from Cantera del Este or Canóvanas. The proposed works will be performed using two types of construction vessels: a derrick barge with a mounted crane that will move the rocks from the rock barge to the proposed structure location, and a rock barge that will bring the fill material from staging areas at wharf 12-14 to the proposed location each morning with the assistance of a tugboat. The derrick barge with a draft of approximately 9 feet will be in-situ during the construction period and remain at the construction site for duration of the construction activities which is approximately between two – three months. The rock barge will remain on site each day for approximately 8-12 hours. The proposed construction will be performed during daytime but the rock loading activities will extend beyond daylight hours. As part of this project, the applicant proposes an educational program that would include a voluntary coral reef planting program and monitoring as part of a community involvement program known as Adopt a Coral.
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:
Avoidance is not an alternative due to the nature/purpose of this project. In accordance to the applicant, the proposed structures were designed at the minimum water depths necessary to mitigate erosion and induce waves to break offshore, and allow passage of aquatic life on and between structures.
COMPENSATORY MITIGATION - The applicant has provided the following explanation why compensatory mitigation should not be required:
The project as proposed will have a net benefit to the environment as it will provide thousands of cubic meters of rock for colonizing organisms.
CULTURAL RESOURCES:
The Corps is not aware of any known historic properties within the permit area, which is the footprint of the three submerged rubble structures in the Atlantic Ocean. 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.
ENDANGERED SPECIES:
