Corps of Engineers releases Rio Guayanilla draft Integrated Feasibility Report, Environmental Assessment for public comment

Published Aug. 28, 2019

The U.S. Army Corps of Engineers (USACE), Chicago District has released for public comment the draft Integrated Feasibility Report and Environmental Assessment for the Río Guayanilla Flood Risk Management Study at the Municipality of Guayanilla, the Commonwealth of Puerto Rico. The draft feasibility report was completed in collaboration with our local sponsor, the Department of Natural and Environmental Resources; primary stakeholder, the municipality of Guayanilla; and the U.S. Fish & Wildlife Service. The study area is the alluvial valley in which the municipality resides, with principal benefits of the plan for Guayanilla and the outlying neighborhoods of El Faro, Playa, and Beldum.


The draft report considers structural and nonstructural management measures to reduce the risk of flooding in the lower watershed at Guayanilla. Features of the proposed alternatives described in the draft report include various diversion channel and levee alignments and types that would direct all flood waters at or above the two-year flood occurrence around the municipality of Guayanilla to the west.


Public meetings are scheduled next month in Puerto Rico to provide more information about the proposed alternative(s), and seek input from members of the community and other stakeholders:
