Army Corps awards key contract to build EAA reservoir foundation for walls

The South Florida Water Management District uses 4,000 pounds of explosives Aug. 28, 2020, to help dig a canal leading to the stormwater treatment area the district is building as part of the Everglades Agricultural Area Reservoir Project.

Construction of the Everglades Agricultural Area reservoir, a key component of the Comprehensive Everglades Restoration Plan, has taken a big step forward.

The Army Corps of Engineers announced Sept. 28 it had awarded a second large contract to construct its portion of the project in western Palm Beach County.

The federal agency will pay between $308 million and $492 million to Forgen-Odin JV of Rocklin, California, to build the foundation for the reservoir's walls.

The contract includes the following features:

  • Clearing

  • Grubbing (shallow digging)

  • De-mucking

  • Blasting

  • Foundation preparation

  • Installation of a seepage cutoff wall

  • Canal backfilling

Construction of the walls — a 17.3-mile-long embankment dam surrounding the 10,500-acre, 78.2 billion gallon reservoir — will be awarded in a separate contract.

The width of the foundation for the embankment dam will be 260 feet in the north, east and west; and 235 feet in the south.

EAA reservoir progress

The EAA reservoir has been at the center of controversy over the past year:

Despite the issues, the Corps has said the construction timetable for the reservoir remains on track.

“This important component will reconnect Lake Okeechobee to the central Everglades and send additional water south to Everglades National Park and Florida Bay,” said Col. James Booth, the Jacksonville district commander.

Once completed in 2029, the reservoir and three adjacent stormwater treatment areas being built on 6,500 acres by the South Florida Water Management District (SFWMD) will encompass 16 square miles — larger than Stuart and Fort Myers combined.

The reservoir will have the capacity to store about half a foot of water from the 730-square-mile Lake Okeechobee, according to SFWMD Executive Director Drew Bartlett. About 46% of the reservoir water will come from the lake, he said.

The total estimated cost of the entire project will be $3.9 billion.
