Río Guayanilla, PR
Construction (C)
Congressional Districts: Puerto Rico


The Rio Guayanilla project area comprises the Guayanilla coastal flood plain located about 16 kilometers west of the city of Ponce. Within the flood plain lies the town of Guayanilla, the Playa de Guayanilla sector, and other rural communities with an affected population of approximately 8,800 residents. A serious flood problem exists as the river passes directly through the middle of the town. Damages associated with flooding have been reported by the municipality ten times in the last twenty-five years. In addition to property damages, a serious risk exists to the lives and well-being of those residing within the flood plain. Frequent flooding seriously impedes the socio-economic development of the community. The Puerto Rico Department of Natural and Environmental Resources (DNER) completed construction of one segment, Phase I, in 2006. No additional construction has been pursued by DNER due to financial conditions of the Commonwealth. The Bipartisan Budget Act of 2018 (BBA18) appropriated $3M to complete a feasibility report. The feasibility study was brokered to the U.S. Army Corps of Engineers (USACE) Great Lakes and Ohio River Division (LRD). The Rio Guayanilla feasibility study was initiated in September 2018. A Chief of Engineers Report was signed on 13 August 2020.
