This study will assess the shoreline problems and provide possible Coastal Storm Risk Management alternatives to reduce risk to infrastructure located along specific areas of Puerto Rico. The study originally considered 13 locations identified by Puerto Rico Department of Natural and Environmental Resources (DNER) to have potential for a feasibility study. These areas are located in San Juan, Carolina, Vega Baja, Arecibo, Aguadilla, Aguada, Rincón, Anasco, Mayaguez, Cabo Rojo, Loiza, Luquillo, and Humacao.

Narrowing of the study areas began with assessing areas of high density of infrastructure at risk from coastal storms which would be an indicator of high potential benefits under a Federal project.  Study scoping resulted in the following areas showing potential for Federal interest: the San Juan (Condado, Ocean Park and Isla Verde) and Rincón coastlines.

The purpose of this study is to determine whether there is Federal interest in a plan to reduce damages to property and infrastructure as a result of erosion, wave attack, and flooding from coastal storms and hurricanes along the Condado, Ocean Park, Isla Verde and Rincon coastlines. Following the study schedule extension, the study team will produce a revised draft report, which will be available for public review.  The report will consider an array of storm damage reduction alternatives and their effects under the National Environmental Policy Act of 1969.

Section 204 of the Flood Control Act of 1970, Public Law 91-611 granted authority for the Puerto Rico Coastal Study. Study funds are appropriated under Title IV, Subdivision B of the Bipartisan Budget Act (BBA) of 2018, P.L. 115-123. The study will examine alternative solutions, and will recommend one plan that meets Corps criteria to be the Tentatively Selected Plan.  If the alternative is supported by Corps decisions makers, it will receive an approved Chief’s Report recommending it for construction.  The plan will then need to receive appropriations for construction.

This study considers the main problem within the San Juan and Rincon focus areas to be coastal storms causing damage to structures and infrastructure due to wave attack, flooding and erosion.

Hurricane and coastal storms are responsible for significant damages to structures and infrastructure due to wave attack, flooding and erosion for the entire island of Puerto Rico. These storm events threaten public and private properties, critical infrastructure as well as recreational and beach areas. Many structures are located along the majority of the study area, including commercial businesses, hotels, condominiums, single family homes,  in addition to roads, public parkland, and public beach access points. Loss of protective beaches and dunes, due to shoreline recession, threatens properties and infrastructure. Sea level rise and coastal storms will continue to exacerbate erosion in the study area, damaging structures and infrastructures and threatening recreational resources. Homeowners and businesses seeking to protect their property have constructed some shore protection measures, such as seawalls, large stone revetments and gabions. Some of the structures and materials used are inadequate to provide significant storm damage protection and are often constructed in an uncoordinated fashion without regard to system-wide coastal processes, exacerbating erosion on adjacent shorelines
