San Juan, Puerto Rico - The U.S. Army Corps of Engineers Jacksonville District is seeking comment starting today on the 2020 Recommended Plan for the Río Antón Ruíz project located in the Humacao Natural Reserve in Humacao, Puerto Rico. 

The Corps has conducted a supplemental environmental assessment (EA) in accordance with the National Environmental Policy Act of 1969, as amended, in order to evaluate changed construction methodologies.  

The purpose of the $4.1 million Continuing Authorities Program Section 1135 project is to provide a permanent solution to reduce the saltwater intrusion into the Humacao Natural Reserve system. The 2020 recommended plan includes the installation of two sheet pile notched concrete cap weirs, at the location of  previously installed temporary salt water intrusion measures; and  placement of approximately 25 feet of riprap adjacent to the weirs, to protect from potential scouring and permanent filling of scour holes. 

Additional details on the 2020 Recommended Plan can be found in the project’s draft supplemental EA at

The Corps is requesting that any questions or comments be submitted, by Thursday, June 11, 2020, to or by mail at:
