SAJ-2011-00551 (SP-TSH)

Published Sept. 25, 2018
Expiration date: 10/24/2018

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 as described below:

CO-APPLICANTS:  Pasco County Board of County Commissioners
                                37918 Meridian Avenue
                                Dade City, FL 33525


                                Florida Department of Transportation
                                Florida’s Turnpike Enterprise
                                Post Office Box 613069
                                Ocoee, FL 34761

WATERWAY AND LOCATION: The project would affect waters of the United States associated with the Pithlachascotee River, Anclote River, and Fivemile Creek. The project would commence at the intersection of Ridge Road and Decubellis / Moon Lake Road (County Road 587) and end at the intersection of Land O’Lakes Boulevard (U.S. Highway 41) and Connerton Boulevard in Pasco County, Florida, Sections 25-29, 32, and 33 of Township 25 South, Range 17 East, and Sections 21, 22, and 27-30, Township 25 South, Range 18 East. The western portion of the proposed project would traverse the Serenova Tract of the Starkey Wilderness Preserve.

Directions to the site are as follows:

Western limits (project start): From the intersection of US Highway 19 (US-19) and Ridge Road, in Port Richey, travel approximately 5.7 miles east along Ridge Road to its eastern terminus. The proposed project would extend Ridge Road eastward from this location.

Eastern limits (project end): From the intersection of State Road 54 (SR-54) and Land O’Lakes Boulevard (US-41), travel north on Land O’Lakes Boulevard approximately 7.3 miles to Connerton Boulevard. The Ridge Road extension would intersect Land O’Lakes Boulevard opposite (west) of Connerton Boulevard.

Basic: To construct a roadway.

Overall: To improve east-west roadway capacity and enhance overall mobility within the area bound by SR-52 to the north, SR-54 to the south, US-41 to the east, and Moon Lake Road, DeCubellis Road, Starkey Boulevard to the west. Also, to provide additional roadway capacity and improved routing away from coastal hazard areas and improve evacuation times in the event of a hurricane, or other major weather-related occurrence, in accordance with State of Florida requirements and the County’s current Comprehensive Plan.

EXISTING CONDITIONS: The proposed road alignment would be located approximately mid-way between SR-52, to the north, and SR-54, to the south. There is an existing overpass where the Ridge Road Extension would intersect the Suncoast Parkway. The proposed road would pass through a range of habitats including mixed wetland hardwoods, cypress, wetland forested mixed, wetland scrub, freshwater marsh, wet prairie, pine plantation, and cattle pasture. The western half of the project, Phase I, would traverse the Serenova Tract of the Starkey Wilderness Preserve (exhibit attached).

PROPOSED WORK: The applicants seek authorization to discharge fill material over 40.16 acres of wetlands for the construction of 8.65 miles of roadway that would extend Ridge Road eastward to Land O’Lakes Boulevard. Wetland impacts would include 37.38 acres of permanent impact and 2.78 acres of temporary impacts. The project is known as the Ridge Road Extension (RRE). The project consists of three segments that include Phase I, an interchange with the Suncoast Parkway, and Phase II. Phase I would be located west of the Suncoast Parkway interchange and would consist of a 4-lane divided roadway that is approximately 4.2 miles in length. The proposed roadway would intersect the Suncoast Parkway approximately 3.2 miles south of SR-52 at an existing overpass. A full diamond interchange and approximately 1 mile of 4-lane divided roadway would be constructed within the limits of the interchange. Phase II would be located east of the Suncoast Parkway interchange and would consist of 4-lane divided roadway that is 3.44 miles in length. An additional 2.78 acres of wetlands/waters are proposed to be temporarily filled/impacted to facilitate construction of the roadway, including bridges. Temporary fill material and/or temporary structures, such as drain pipes, coffer dams, etc., would be removed upon completion of construction and the area would be returned to pre-construction contours and hydrologic conditions. Best management practices, such as underlying temporary fill with geotextile, would be incorporated to minimize impacts and ensure clean removal of temporary fill material.

Previous iterations of this project proposed Phase II as a limited access roadway, allowing only one access point to a commercial parcel located on the east side of the interchange. The applicants now propose to design Phase II as an arterial roadway that would allow as many as seven (7) signalized intersections (also referred to as “full movement intersections”) between the Suncoast Parkway and Land O’Lakes Boulevard (US-41). This public notice is being published primarily due to this change in status of Phase II. The precise number and location of potential intersections is not yet known and the applicants are not seeking authorization for any impacts to waters of the United States that may be associated with these potential intersections or associated developments. Pasco County has stated that developers would be responsible for obtaining authorizations for any impacts to waters of the United States beyond those currently proposed for construction of the Ridge Road Extension.

Note: The proposed Ridge Road Extension was previously noticed by the Corps on November 28, 2011. Additional information, including the Alternatives Analysis previously submitted to the Corps, is available on the Corps’ website at the following address: .

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:

Per the 2011 public notice the project proposed a total of 59.41 acres of wetland impacts that included 56.63 acres of direct impacts and 2.78 acres of temporary impacts. These impacts were broken down as follows:

Wetland Impacts - 2011 Public Notice (acres)





Phase I & II












Modified Alternative 7 (Mod 7) incorporates many new and significant minimization measures for the two Pasco County proposed segments of the RRE. Mod 7 does not change any aspects of the Florida’s Turnpike Enterprise (FTE) segment of the project, the interchange of RRE with the Suncoast Parkway, as described in the 2011 public notice. The horizontal alignment for all of Mod 7 remains unchanged from that shown in the 2011 public notice.

Under Mod 7, Phase I incorporates the lengthening of three bridges that were in the 2011 public notice and the addition of 12 new bridges over wetlands that greatly reduce the permanent wetland fill impacts. The lengthened bridges include the two at W-10 (Pithlachascotee River) and one at W-15 (unnamed). An added benefit of the bridges is greatly reduced encroachment within the floodplains. The following table summarizes the location and length of bridges over wetlands within Phase I of the project.

Four additional upland wildlife crossings were incorporated into the Phase I segment of the project for a total of six. The crossing locations and sizes were coordinated with the US Fish and Wildlife Service. The addition of the bridges and wildlife crossings necessitated substantial revisions to the vertical alignment of the Phase I segment of the project. The applicant took advantage of the revised vertical alignment to incorporate additional segments of vertical wall to replace fill slopes and further reduce wetland impacts.

Within Phase II, minor changes to the vertical alignment were made to accommodate the addition of two upland wildlife crossings and size modification of two others at locations coordinated with the U.S. Fish and Wildlife Service. Additional segments of vertical wall were incorporated into Phase II to minimize impacts to wetlands and reduce floodplain encroachment.

The Wetland Minimization Summary table, provided as a separate attachment with this narrative, summarizes the location and type of minimization techniques utilized on the project. This includes all the bridges over wetlands as well as the specific locations of vertical walls used to reduce fill impacts within wetlands.

Avoidance and minimization opportunities for the interchange segment of the project were limited since the alignment of the proposed roadway through the interchange is fixed by the location of the existing overpass bridge on the Suncoast Parkway. Avoidance and minimization measures employed at the proposed interchange location include the use of 2:1 side slopes and limiting clearing and grubbing activities to areas necessary for construction.

After incorporation of the minimization techniques described above, the proposed project has 37.38 acres of unavoidable direct impacts to waters of the United States. That is a reduction of 19.25 acres since the 2011 public notice. A summary of the direct impact acreage is as follows:

Phase II












 *Reduction in wetland impacts within the interchange segment result from a minor revision to jurisdictional limits based on the 2017 PJD compared to the limits used for the 2011 public notice.

The proposed change of access classification for RRE Phase II from limited access as proposed by Mod 7 to arterial will not change the computed wetland impacts associated with the project. With RRE Phase II classified as an arterial the entity desiring to connect to Phase II will be responsible for obtaining all necessary local, state and federal environmental permits associated with the access connection and adjacent development. That entity would also be responsible for any compensating mitigation required by those permits.

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

Pasco County proposes to provide compensatory mitigation to offset all unavoidable impacts to wetlands within Phases 1 and 2 through the purchase of Mitigation Credits from the Old Florida Mitigation Bank.

For the Florida Turnpike Enterprise (FTE) segment of the project, the 2011 public notice featured three options for compensatory mitigation: preservation of the Cone Borrow Pit, excess mitigation from the Suncoast Parkway or the purchase of credits from the Conner Tract. FTE now proposes to provide compensatory mitigation via one of two options. The first option is per FTE’s Draft COE Mitigation Plan dated March 13, 2018 that proposes the use of the available unused 5% wetland impact contingency and surplus federal mitigation credits from the original permit for the Suncoast Parkway Project 1 – Ridge Road Interchange (199604305 [IP- MN]). FTE’s mitigation plan is currently under review by the Corps. If the Corps does not accept the submitted Draft Mitigation Plan, FTE’s second option is the purchase of mitigation credits from the Old Florida Mitigation Bank. If the Corps accepts the Draft Mitigation Plan in whole or part but the accepted credits are insufficient to offset all of the unavoidable impacts the FTE would purchase any additional credits needed from the mitigation bank.

CULTURAL RESOURCES: The Corps is aware of historic property/properties within or in close proximity of the permit area. The Corps has previously completed 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. Based on the previous consultations, the Corps does not expect historic properties to be affected by the proposed project.
