About this file
This file contains dredge permit plans prepared by Foster Consulting for the Collier County Sheriff's Office (CCSO) Marco Substation Floating Dock project located at 990 N. Barfield Drive, Marco Island, Florida. The project encompasses dredging operations in the N Cedar Waterway (Tidal) to facilitate future emergency vessel lift utilization. The proposed dredge area totals 4,000 square feet with an approximate removal volume of 163.39 cubic yards of dredged material distributed across four sections: Section 01 (43.09 cubic yards), Section 02 (22.41 cubic yards), Section 03 (48.06 cubic yards), and Section 04 (49.83 cubic yards). The dredge plan establishes a 5-foot buffer zone around the work area and identifies a loading/unloading site on land at the western end of the project. Sealed bids are due February 23, 2026, at 3:00 p.m., with a non-mandatory pre-bid meeting and site visit scheduled for January 26, 2026, at 10:00 a.m. at the project site.
The permit plans specify comprehensive environmental and operational controls to minimize project impacts. Turbidity management is required through the installation of floating turbidity booms secured to shorelines and maintained throughout dredging activities, with two monitoring stations established to ensure compliance with state water quality standards. The contractor may utilize either mechanical dredging methodology employing a barge-based excavator with de-watering on the construction barge or hydraulic dredging methodology using settling containers and geotube filtration systems, with return water piped back to the original dredge area. All dredged materials must be de-watered and transported in sealed trucks to an off-site spoil site. Loading and unloading operations require silt fences and hay bales to prevent sediment runoff. The plans reference mean high water elevation of +0.35 feet NAVD 1988 and mean low water elevation of -1.66 feet NAVD 1988, with the proposed dredge depth reaching -6.66 feet NAVD or -5 feet at mean low water.

GENERAL NOTES 02
SPECIFICATIONS
1.TURBIDITY
1a. Turbidity will be minimized for both magnitude and duration to the maximum extent practicable.
1b. Turbidity at the outside edge of the project area shall not exceed federal and state water standards.
1c. Management practices and suitable technology are implemented for all stationary installations including those created for drainage, flood control, or by dredging or filling; and there is no alternative to the proposed activity, including the alternative of not undertaking any change, except at an unreasonably higher cost.
1d. A turbidity curtain shall be used only during in-water work to minimize any potential impacts on natural resources.
2. DE-WATERING
2a. De-watering of dredged materials will take place on the construction barge.
3. OFFLOAD SITE
3a. Once materials are de-watered they will be hauled to a spoil site determined by the contractor in sealed trucks.
4. LOADING/UNLOADING
4a. Loading and unloading of equipment will take place on land at the western end of the project area.
5. The contractor shall provide access to the canal as requested and only at times when the water quality within the project area does not exceed water quality standards.
6. DREDGING METHODOLOGY
6b. Mechanical Dredging Methodology: Prior to dredging, a floating turbidity boom will be installed around the proposed dredge area. The boom will be secured to the shoreline on each side of the project and will maintain contact to the bottom at all times. The boom will be secured to the shoreline on each side of the project and will maintain contact to the bottom at all times. The boom shall be maintained throughout dredging activities. Two monitoring stations will be established to monitor turbidity containment. Water testing and reporting will be conducted as required per permit stipulations throughout the dredging activities. The turbidity boom shall be left in place until all suspended sediments have fallen out of the water column and the water within the area meets state water quality standards, at which point it will be removed. The dredge material will be loaded into a container on a barge using barge based excavator, and will be transported to the offloading site along the shoreline/parking lot for unloading. The offloading site will have staked silt fences and hay bales to prevent any sediment runoff during the offloading activities.
The dredge material will be placed into sealed trucks using a land based excavator and will be transported to an off-site spoil site. The spoil disposal site will have staked silt fences and hay bales to prevent any sediment runoff. No discharge or return water will be allowed to reach wetlands or nearby water bodies. OR 6c. Hydaulic Dredging Methodology: Dredging may be performed using a hydraulic dredge pump. This hydraulic pump will then pump the slurry to sealed (watertight) containers that will be staged near the terminal end of the canal. The settling containers will be monitored continuously to ensure the capacity of the containers are not exceeded. The dredged sediments will be dewatered within the settling containers through gravity settling. A baffle system will be used to allow the water to spill over and then be piped back to the original dredge area. This process will be monitored to ensure dredged material and/or return water will not spill and enter stormwater drains. An alternative approach will be using a geotube within the container, the sediments will be filtered through the tube. The return water from the geotube would be piped back into the original dredge area. Hay bales are proposed at either end of the containers in series and surrounding any stormwater catch basin. The project areas will be left clean and returned to previous conditions.
