Published June 12, 2019
Expiration date: 7/2/2019

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) as described below:



                      19 West Flagler Street, Suite 1212

                       Miami, Florida 33130


WATERWAY AND LOCATION:  The project would affect waters of the United States associated within the Florida Southeast Coast, Southern Florida Basin (HUC_08: 03090206).  The project site is located between NW 130 and 138 Streets and NW 127 and 132 Avenues, in Section 26, Township 52 South, Range 39 West, Miami-Dade County, Florida.

Directions to the site are as follows:  From the Florida Turnpike take the Okeechobee Road Ext, travel south ½ mile on NW 118 Avenue, northwest 1 mile on NW 136 Street to northeast corner of the property.



                                                                            Longitude -80.409530°



Basic:  Limestone Mining

Overall:  To provide affordable, high-quality construction grad aggregate that satisfies the public need for such material within peninsular Florida, defined as geographically comprising Florida Department of Transportation Districts 1, 2, 4, 5, 6, and 7.


EXISTING CONDITIONS:  The wetland system consists of 130 acres of dense melaleuca, 12 acres of dense melaleuca saplings and 14 acres of prairie (FLUCCS 641) with 50-75% melaleuca for a total of 156 acres of jurisdictional wetlands. 


PROPOSED WORK:  The applicant seeks authorization to mine limestone on the 156 acre project site. During the mining process, the area is first demucked, the demucked area is filled with limestone aggregate to provide a stable work platform and then the filled area is excavated to produce the limestone aggregate. Out of the total 156 acre property, 133 acres will be excavated and 23 acres will remain as a 100’ littoral area around the perimeter of the excavated lake.


PROJECT HISTORY:  A Record of Decision (ROD) and regional Statement of Findings was finalized on January 29, 2010 on the May 2009 Final Supplemental Environmental Impact Statement (FSEIS) on Rock Mining in the Lake Belt Region of Miami-Dade County, Florida (Lake Belt FSEIS) for ten (10) Department of the Army permit applications comprised within the Lake Belt FSEIS. The Corps determined that a modified version of Alternative 3 including on-site avoidance areas, staged mining and special conditions known collectively as “Modified Alternative 3” is the Least Environmentally Damaging Practicable Alternative (LEDPA). The Corps authorized project includes; 1) after-the-fact authorization for discharges of dredged or fill material into 2,717 acres of wetlands that took place between February 2002 and January 2009, 2) discharge of dredged or fill material into 7,327 acres of wetlands. The 7,327 acres of wetland impacts have been divided into two (2) geographic areas: Section I (4,591 acres) and Section II (2,736 acres).


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:  Avoidance and minimization was accomplished through the Lake Belt Plan adopted by the Florida Legislature, by concentrating the mining in the eastern 4 miles of the Lake Belt and establishing a mitigation fee to fund the acquisition and restoration of the Pennsuco wetlands in the western portion of the Lake Belt. The Pennsuco wetlands include approximately 12,600 acres and in the Lake Belt Mitigation Committee 2017 Annual Report, it was estimated that approximately 88% of the Pennsuco wetlands have been or are currently being treated to remove exotic vegetation.


COMPENSATORY MITIGATION – The applicant has offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:  The wetland impact in terms of the Wetland Rapid Assessment Methodology (WRAP), as calculated for the Lake Belt Permits is shown below:




Proposed Wetland Impacts

Dense Melaleuca Saplings






WRAP units/acre





WRAP units






Per Table 3 in the 2018 Annual Report Supplemental Mitigation Summary, the cumulative wetland units balance at the end of 2017 was 2,941.7 units. The 69.7 WRAP units associated with this project will not significantly affect the overall Lake Belt Mitigation balance. Additional Lake Belt mitigation fees will be collected as a result of this additional mining and will be utilized by the Lake Belt Mitigation Committee to obtain additional mitigation credits.

The project will also result in 23 acres of littoral area, which will also contribute to a positive mitigation balance.


CULTURAL RESOURCES:  The Corps is not aware of any known historic properties within the permit area.  By copy of this public notice, the Corps is providing information for review.  Our final determination relative to historic resource impacts is subject to review by and coordination with the State Historic Preservation Officer and those federally recognized tribes with concerns in Florida and the Permit Area.


ENDANGERED SPECIES:  The property was included in the January 11, 2010 US Fish and Wildlife Service (FWS), Biological Opinion (BO) as part of a full Lake Belt mining alternative (LBMA) (SEIS Alternative 8) and its effects on the endangered wood stork (Mycteria americana). The BO addressed limerock mining during the full 30-year period addressed in the Corps May 1, 2009, Final Supplemental Environmental Impact Statement on Rock Mining in the Lake Belt Region of Miami-Dade County, Florida (FSEIS). FWS reviewed the status of the wood stork, environmental baseline for the action area, effects of the proposed action and the cumulative effects, determined the LBMA is not likely to jeopardize the continued existence of the wood stork. No critical habitat has been designated for the species, therefore none would be affected. FWS BO provided reasonable and prudent measures necessary and appropriate to minimize impacts of incidental take into the design of the proposed action. The Corps will request initiation of formal consultation with the FWS pursuant to Section 7 of the Endangered Species Act by separate letter.

The wetlands on the property are predominately dense melaleuca. According to the 2010 BO, the endangered Everglade snail kite (Rostrhamus sociabilis plumbeus) may occasionally occur in the Lake Belt project area as habitat conditions that provide the necessary hydrology for growth and development of populations of prey species (apple snail (Pomacea paludosa)) important to snail kites are present. Dense growth of melaleuca in much of the project area would prevent kites from foraging. Snail kites have not been documented nesting within the Lake Belt and hydrologic changes that may result from the mining projects are also not expected to affect hydrologic changes that may result from the nesting areas adjacent to the project within WCA-3B. FWS stated any impacts to potential snail kite foraging habitat are expected to be insignificant and discountable, thus the proposed action is not likely to adversely affect the snail kite. The Corps will request initiation of formal consultation with the FWS pursuant to Section 7 of the Endangered Species Act by separate letter.

The project is located within the consultation area of the Florida bonneted bat (Eumops floridanus). This species was not evaluated during the 2010 BO.  The project site consists of dense growth of melalueca, therefore the Corps has determined that the proposed project “may affect” the Florida bonneted bat and will request initiation of formal consultation with the FWS pursuant to Section 7 of the Endangered Species Act by separate letter.
