Rio Grande de Manati Chief’s Report signed

Lt. Gen. Scott A. Spellmon, USACE Commanding General and 55th U.S. Army Chief of Engineers, has signed the Rio Grande de Manati Chief’s Report.

Several communities within the Municipality of Ciales, Puerto Rico, are located within the Rio Grande de Manati’s active floodplain.

The Rio Grande de Manati has reached flood stage 35 times in the past 50 years, resulting in damages that range from frequent nuisance flooding to severe and widespread impacts.

The Army Corps designed the recommended plan to reduce flood risks to communities in this region. The signing of the report progresses the project to Congress for authorization.

Among others, the plan calls for channelization/channel modification, construction of floodwalls, major levee works, etc.

According to the Corps, channel modifications would include channel realignment through the field opposite of Dos Rios to improve hydraulic conductivity.

The channel would be designed to increase capacity and create improved floodplain connection. This option also includes a floodwall or ring levee around the wastewater treatment plant to protect this critical infrastructure that also serves areas outside of Dos Rios and Alturas de Ciales.
