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: City of Port Saint Lucie
c/o Colt Schwerdt
121 SW Port St. Lucie Blvd
Port St. Lucie, FL 34984
WATERWAY AND LOCATION: The project site western boundary is the confluence of City Canals E-3 and E-3 B (southeast of the SW Californian Blvd & SW Del Rio Blvd intersection) and the eastern boundary is the confluence of the E-3 Canal and SW California Blvd, in Sections 1 and 6, Township 37 North, Ranges 39 and 40 East, in Port Saint Lucie, within Port Saint Lucie County, Florida.
Directions to the site are as follows: Take I-95 to Crosstown Parkway in Port Saint Lucie. Head east until SW Cashmere Boulevard, turn right. Go to end of street and turn left on SW Del Rio Boulevard. Turn right on SW California Boulevard and the canal will be on the right hand side of the road.
APPROXIMATE CENTRAL COORDINATES:
Basic: The basic project purpose is for canal maintenance and safety.
Overall: The overall project purpose is for canal maintenance and safety located within the City of Port Saint Lucie, in Saint Lucie County.
EXISTING CONDITIONS: The E-3 Canal Bank Stabilization Project is located in the City of Port St Lucie. The project segment of the E-3 canal is approximately 1.46 miles long. The upstream limits begin at the confluence of the E-3 and E-3B Canals, generally located southwest of SW Beeker St. /SW Sudder Ave, and the downstream project limits are at the intersection of the E-3 Canal with SW California Blvd. The E-3 canal is connected to the E-4 canal via double 91Â” x 58Â” elliptical concrete pipes crossing SW California Blvd. The E-4 Canal continues southeast and then northeast until it intersects the Monterrey Waterway. The Monterrey Waterway flows southeast until it meets the SFWMD C-24 canal. A control structure at the confluence of the Monterrey Waterway and the C-24 maintains the surface water elevation of the Monterrey Waterway at 9.36Â’ NAVD.
PROPOSED WORK: The applicant is proposing to replace an existing open water canal system with a dual culvert system that shall be buried for the entire length of the E-3 Canal, approximately 1.46 miles. The project has been divided into three (3) phases with increasing sizes of culverts to accommodate the increasing runoff form contributing areas discharging into the system. Conveyance swales will be provided to direct runoff into the proposed ditch bottom inlets. Existing corrugated metal pipe (CMP) cross drains that discharge into the E-3 Canal will be replaced with high density polyethylene (HDPE) pipes. Existing HDPE cross drains will be extended to connect to the proposed culverts. All canal banks located within the canal transitions between the end of the proposed culverts and the existing canal at the end of each phase will be stabilized and armored at all side canal connections. The total amount of fill to be discharged for all phases is 82,686 cubic yards with 4,696 tons of riprap for armoring and stabilization at the side canal connections. The applicant is proposing to impact a total of 2.71 acres of waters located within the project scope boundary.
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 applicant will adhere to construction methodologies following City of Port Saint Lucie and Florida Department of Transportation technical specifications. Construction activities will be performed, for the most part, during the dry season to minimized impacts to the water quality. Silt fences will be installed along the limits of the construction during each phase to avoid sedimentation into the adjacent properties. The silt fence will be inspected weekly and after every rain event to verify integrity. Silt fences will be repaired immediately if a breach has been detected. Floating turbidity barriers will be installed and Soil tracking devices will be installed at every egress location to avoid tracking soils offsite.
COMPENSATORY MITIGATION –
The applicant has provided the following explanation why compensatory mitigation should not be required:
Efforts to minimize impacts to intersecting canals and ditches will be made through the installation of riprap to protect against washouts and erosion. Large portions of the proposed fill activity will take place within canals that were dug from upland sources and therefore will not require compensatory mitigation.
