TO WHOM IT MAY CONCERN: The Jacksonville District of the U.S. Army Corps of Engineers (Corps) has received an application for a Department of the Army permit pursuant to Section 404 of the Clean Water Act (33 U.S.C. §1344) and Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. §403) as described below:

APPLICANT: South Florida Water Management District
                      3301 Gun Club Road
                      West Palm Beach, Florida 33406

WATERWAY AND LOCATION: The project, Stormwater Treatment Area (STA) 1W would affect waters of the United States associated with Hillsboro Canal. The 2,274-acre project site is located in Section 31, 32, 33, and 4, of Township 45 South, Range 39 East, Palm Beach County, Florida.

Directions to the site are as follows: From Interstate 95 travel west on Southern Boulevard for 20 miles to the CR 880 intersection. Travel approximately 4 miles to the G-310 entrance located north of the existing STA 1W project site. Travel approximately 10 miles south within the STA 1W project through G-310 pump station and along the L-7 Canal levee to the project site.


Latitude:     26.516434°
Longitude: -80.462829°


Basic: Water quality improvements.

Overall: The purpose of STA 1W Expansion 2 is to improve phosphorus treatment capacity of the existing STA 1W and assist in achieving the water quality based effluent limitation (WQBEL) for existing flows to the Water Conservation Area (WCA) 1.

EXISTING CONDITIONS: The project site consists of an undeveloped property. Portions of the project site were used in the past for sugar cane production. The agricultural operation over the lands ceased in 2017. A large portion of the property, located to the south and east of the old agricultural fields, consists of freshwater marshes. The project site is immediately south of the existing STA 1W facility, west of Arthur R. Marshall Loxahatchee National Wildlife Refuge, east of the Hillsboro Canal and just north of the S-6 pump station

The upland land uses within the project site consist of berms and levees constructed from spoil dredged from the adjacent ditches. Access dirt roads and trails exist on the top of the berms and levees. The predominant vegetation observed sparingly throughout the upland areas consists of Broom grass (Andropogon virginicus), Knotroof Bristlegrass (Setaria geniculata), Wiregrass (Aristida stricta), Saw palmetto (Serenoa repens), Cabbage palms (Sabal palmetto), Bull Thistle (Cirsium vulgare), Bahia grass (Paspalum notatum), Crowfoot grass (Dactyloctenium aegyptium), and Slash pine (Pinus elliottii).

The wetland areas consist of freshwater marshes and old agricultural fields which have developed hydrophytic vegetation communities, have hydrologic conditions conducive of wetlands and contain hydric soils. Melaleuca (Melaleuca quiquenervia), Carolina willow (Salix caroliniana) and Brazilian pepper (Schinus terebinthifolius), plants that are categorized as nuisance or exotic invasive species, are observed within the wetlands. Also, towards the south, cattails (Typha latifolia) were observed.

PROPOSED WORK: The applicant seeks authorization to expand STA 1W, to include 2,274 acres of treatment cells, canals, levees, pump stations, and water control structures. The project results in the discharge of fill in 118 acres of wetlands and 30 acres of waters.

The proposed actions include the construction of treatment cells dominated by Submerged Aquatic Vegetation (SAV) and Emergent Aquatic Vegetation (EAV). The inflow will consist of a series of structures that will convey water from the existing STA 1 West discharge canal into the proposed project through a connector canal. A divide structure is proposed on the existing STA 1 West discharge canal to allow conveyance into the proposed expansion area. The water will flow from north to south through the treatment cells and treated water will collect in a discharge canal along the southern boundary of the project. The proposed discharge canal will convey treated water towards a proposed pump station for discharge into the WCA 1.

The parcel where the project is proposed consists of vacant agricultural parcels that were formerly used for sugar cane production. Sugar cane production over the project lands ended in 2017, surface water management ceased, and the land has developed wetland characteristics now. The canals and wetlands to be impacted by the project construction include filling generated from the degradation of berms and roads that exist adjacent to the canals. Fill material excavated from the project canals will be used for levee construction. No import of fill is proposed.

The source of inflows for the expansion area is treated water from the existing STA-1 West. In order to move flow into the Expansion No. 2 area, a 500 CFS pump is proposed at the inflow location within the STA 1 W Expansion No. 1 project area. The inflow pump routes water into an approximately 5.5-mile long connector canal running north-to-south parallel to the west of the L-7 Canal. The connector canal will inflow into the northern distribution canal of the STA-1W Expansion 2 treatment component, which will distribute the inflow between the 3 treatment cells proposed. After treatment, water leaving the STA-1W Expansion 2 project will get collected and pumped through a proposed 625 CFS pump (Outflow Pump Station) into WCA-1.

The vegetation in STA-1W Expansion 2 project will be dominated by SAV with some EAV cultivated throughout the area to provide treatment or functional redundancy, reduce wind fetch of the open water and minimize potential wave action that could damage SAV. The treatment cells outflow spillway structures will convey treated flows to a new discharge canal located along the western and southern edge of the expansion area, outside the treatment areas, that will route treated water to the proposed outflow pump station to enable discharges to the Refuge (WCA 1).

AVOIDANCE AND MINIMIZATION INFORMATION – The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:

“The construction of the STA 1W Expansion 2 is unavoidable as it is required by Florida Department of Environmental Protection permits and consent orders issued to the SFWMD. Several project alternatives were evaluated to reach the selected project.”

COMPENSATORY MITIGATION – The applicant has offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:

“The unavoidable impacts to waters of the United States are offset by STA 1W Expansion 2's post project conditions consisting of submerged aquatic vegetation and emergent vegetation treatment cells.”

CULTURAL RESOURCES: The Corps is aware of an historic property (Hillsboro Canal) within or in close proximity of the permit area. The Corps will initiate consultation with the State Historic Preservation Office and those federally recognized tribes with concerns in Florida and the Permit Area, and the Advisory Council on Historic Preservation as applicable pursuant to 33 CFR 325, Appendix C and Section 106 of the National Historic Preservation Act, by separate letter.

ENDANGERED SPECIES: The project site is located in the consultation area for Audubon's Crested Caracara and the Everglades Snail Kite. The site is also located within the core foraging area of two wood stork nesting colonies (619315 and Loxahatchee 1). The site is located in Everglades Snail Kite designated critical habitat and contains suitable habitat for the Eastern indigo snake.

The Corps has determined the proposed project may affect, but is not likely to adversely affect the Audubon's crested caracara, wood stork, Everglades snail kite, and the Everglades snail kite designated critical habitat. The Corps will request U.S. Fish and Wildlife concurrence with this determination pursuant to Section 7 of the Endangered Species Act.

The Corps has determined the proposal may affect the Eastern indigo snake. The Corps will request initiation of formal consultation with the Fish and Wildlife Service pursuant to Section 7 of the Endangered Species Act by separate letter.

The Corps has determined the proposal would have no effect on any other listed threatened or endangered species or designated critical habitat.

ESSENTIAL FISH HABITAT (EFH): This notice initiates consultation with the National Marine Fisheries Service on EFH as required by the Magnuson-Stevens Fishery Conservation and Management Act 1996. No EFH is located within or areas affected by the project. Our initial determination is that the proposed action would not have a substantial adverse impact on EFH or Federally managed fisheries in the South Atlantic Region.

33 U.S.C 408 (SECTION 408): The proposed project includes work in the Hillsboro Canal and levee, a federal project. Therefore, a Section 408 approval may be required.
