San Juan Metro Area PR CSRM Study
Investigations (I)
Congressional District: Puerto Rico


The San Juan Metro Area Coastal Storm Risk Management (CSRM) study will extensively leverage the NACCS lessons learned, tools, and processes to ultimately produce a comprehensive and consistent understanding of coastal vulnerability in the San Juan Metro Back Bay area. The majority of Puerto Rico’s population live within the San Juan Metro area and the vast majority of critical infrastructure investments such as hospitals, schools, power plants, government buildings, and roads are located near the coastally influenced bays, lagoons and canals in the San Juan Metro area. A proactive approach is key to potentially minimize or even avoid impacts of both extreme and nuisance events in the future. The study area has suffered extensive damage from multiple tropical and extratropical storms to include Hurricane Hugo (1989), Hurricane Luis (1995), Hurricane George (1998), Nor’easter (2008), with the most recent Hurricanes Irma and Maria (2017) and Nor’easter (2018). Hurricanes on average hit Puerto Rico about once every three years and strong Nor’easters every 10 years. In addition to regional analyses of coastal vulnerability, the strategy will identify initial measures/costs that can address vulnerabilities with emphasis on regional sediment management (RSM) as an actionable strategy to sustainably maintain or enhance current levels of storm protection within existing authorities.
