Thank you for your message. It is my understanding that the U.S. Army Corps of Engineers is investigating to determine whether the

work remains in compliance with the issued permit.

Dear Mrs. Lisamarie Carruba,

I am writing to report the impact of the erosion control methods that were implemented today, March 3, 2015 in the Puerta deTierra area. These photographs were taken between at 5:20 and 5:40PM at the area in front of El Hamburger. It looks like the

stone berm and trench are not working to prevent transport of sediments as there is a significant amount of sediment seepingoutside the beach area. The plume extends westbound along the shoreline. The Historic Wall on the east side appears to had been

impacted as part of it has collapsed into the ground.

The photographs that you mentioned previously were taken by Dr. Edwin Hernandez as part of his preliminary inventory that he

made were he determined the presence of A. Palmata.

Dr. Edwin Hernndez, in collaboration with his team from SAM and UPR-CATEC, found that there were multiple colonies of A.

Palmata located within 50 m or less from the shoreline. Preliminary observations suggested that, nearly the entire surveyed

segment dominated by colonized pavement and patch reefs constituted part of the Acroporid corals DCH. Though only one colonyof O. Faveolata was observed during the preliminary inspection, and though no DCH has been officially designated yet for this

species, this habitat represents also critical habitats for its presence.

As a very concerned citizen, I respectfully request that this is investigated right away as this seems to be an urgent situation. I hope

you act to remedy it immediately.

Sincerely,

Sonia Villaverde

Sonia:

Thank you for your message and for the report you sent. I also received a message regarding this project from MaryAnn today.

For your information, this project is an erosion control project to address the severe landslide conditions that led to a portion ofthe sidewalk collapsing. The stones that have been placed parallel to the coast were put there at our recommendation to trap

sediments as they are working, leaving the area behind them with a trench where the sediments accumulate and are then

cleaned out along with construction debris as work is done. The project is being undertaken by the Puerto Rico Highway and

Transportation Authority and is permitted by the Corps of Engineers. There will be a series of erosion control measures, includingvegetation planting, to try to prevent future landslides in this area that do lead to harm to the coral reef ecosystem just offshore.Unfortunately, any projects of this type do lead to temporary impacts but, from your photos, it looks like the stone berm and

trench are working to prevent major transport of sediments outside the beach area.

National Marine Fisheries Service and the PR Department of Natural and EnvironmentalResources" written by Dr. Edwin A. Hernndez-Delgado (1,2,3) with the collaborationof Ivangs Rivera (1) and Samuel Suleimn Ramos (1).

(1) Sociedad Ambiente Marino (SAM) (2) University of Puerto Rico Center for AppliedTropical Ecology and Conservation (UPR-CATEC) (3) University of Puerto Rico

Department of Biology.The objective of this preliminary assessment of Puerta de Tierra marine naturalsystems was to:

1) Provide a rapid qualitative assessment of adjacent benthic communities across thepotentially impacted zone by project Paseo Lineal de San Juan northern segment(currently referred to as Paseo Lineal de Puerta de Tierra);

2) Determine if there were ESA-listed coral species across adjacent coral reefs;

3) Determine the spatial extension of Acroporid coral designated critical habitats (DCH)

across the zone; and4) Determine the spatial extension of essential fish habitats (EFH) across the zone.Surveyed benthic habitats showed the common presence of Endanged Species Act(ESA)- listed Elkhorn coral (Acropora palmata) and a very low abundance of theLaminar star coral (Orbicella faveolata) within less than 200 m from the shoreline.

Dr. Edwin Hernndez, in collaboration with his team from SAM and UPR-CATEC,found that there were multiple colonies of A. Palmata located within 50 m or less fromthe shoreline. Preliminary observations suggested that, nearly the entire surveyedsegment dominated by colonized pavement and patch reefs constituted part of theAcroporid corals DCH. Though only one colony of O. Faveolata was observed during

the preliminary inspection, and though no DCH has been officially designated yet forthis species, this habitat represents also critical habitats for its presence. The existingcoral biodiversity preliminarily documented in this survey showed a total of 26 specieswithin 700 linear meters of reefs along the shoreline, including 3 hydrocorals, 11octocorals and 12 scleractians or hard corals.

A preliminary survey of fish fauna also showed a total of 59 species, belonging to 37genera and 25 families. This is only a preliminary list and future surveys may guaranteethat this list is likely to grow. The surveyed reef segment constitutes a very importantessential fish habitat (EFH) for multiple reef fish species, including species managed bythe Commonwealth of Puerto Rico and the National Marine Fisheries Service (NMFS).

There was also presence of submerged aquatic vegetation (SAV) across the adjacentbenthic systems, but environmental impacts of the project Paseo Lineal of Puerta deTierra (formerly named Paseo Lineal San Juan) to any of these marine ecosystemswere not addressed. A massive landslide is significantly impacting the shoreline andadjacent coral reefs ecosystems.

The recommendation is that there is a need to immediately stabilize an active landslidein that coastline to reduce further impacts to adjacent coral reefs and SAV, includingDCH of Acroporid corals.

There is a need to:

1) Determine the spatial extent of Acroporid coral DCH across adjacent reef bottoms;

2) Determine the presence of any of the seven ESA-listed coral species acrossadjacent reef bottoms;

3) Address impacts to EFH; and4) Initiate consultation with NMFS under section 7 of ESA; and

5) Prepare an Environmental Impact Statement in full compliance with Law 147 of1999.

There is no evidence in the available public record of this project that the constructionof an abandoned breakwater in navigable waters of the Atlantic Ocean was permittedby the US Army Corps of Engineers. This should also be addressed. According to theavailable public record, potential environmental impacts of this project on coral reefecosystems were not addressed. It should be noted that the tracking number of the

Notice of Intent submitted to the EPA does not yield any results. This should also beexamined.

There is significant potential for permanent adverse impacts on coral reefs associatedto the construction of this project could be significant and permanent and must beimmediately addressed.

I would like to thank you for the attention given to this matter.

Sincerely,

Sonia Villaverde
