The U.S. Army Corps of Engineers, Jacksonville District (Corps), proposes to construct two segments of earthen levees (~2 miles), a cutoff channel (~197-ft), drainage structures, interior drainage channels, and three paved road ramps across the levees to reduce flood damages to the southwest portion of Aguadilla and the community of Espinar in Aguada. Refinements to the conceptual design are expected during PED based on results from an updated Hydrology and Hydraulic model.
Changes to the project since the completion of the 2004 report include revisions to the cost-benefit analysis and updates to the project design. Design changes include the use of concrete (instead of metal) culverts, armoring for the cutoff channel, and revisions to the levee side slopes to meet current Corps levee design guidance criteria. The dimensions of the levees increased when the side slopes went from 2.5:1 in the 2004 plan to 3:1 in the 2015 plan.
