2011 East Naples Bay Dredging Project

The Project:
The East Naples Bay Dredging Project is set to begin in July 2011. Energy Resources, Inc. has been awarded a $2.3 million contract to dredge 16,700 CY of sediment from the canals to a depth of -5.0’ MLW (-5.4’ NGVD 29) with a possible overdredge to a depth of -5.5 MLW (-5.9’ NGVD 29). Their subcontractor, SteMic Marine Construction will excavate more than 2,300 CY of rock and install a rip-rap (stone) slope protection under the US 41 Bridge as part of a permit requirement to mitigate environmental impacts. Dredged material will be dewatered at the City Yard on Riverside Circle before final disposal at the Collier Landfill.
In the coming weeks the level of activity will increase in the waterways as the contractor begins mobilizing equipment by early August. Energy Resources will create a video record of existing conditions prior to dredging. Structural evaluations of waterfront properties and structures will also be conducted prior to construction in order to ensure safe operating levels at which to remove rock. More detailed surveys of private property may be requested by the contractor.
The project is expected to be completed by July 2012; however shut-downs due to hurricanes, tropical storms or other events out of the contractor’s control may prolong the completion date without penalty.


Needed Cooperation:

Please help to share this information. We appreciate any first hand information about the locations of rock out-croppings.
The contractor will notify each resident along a canal prior to starting work on that canal. It will be critical for residents (upon notification) to keep vessels out of the main dredging channel and even more helpful if owners could temporarily relocate their vessels out of the canal for the short time the area is being dredged. Turbidity curtains will be placed across the canal opening during dredging and residents that wish to enter or exit the canals while work is underway will need to wait for work to stop.


Limited Time Opportunity for Private Dock Dredging:
Residents who would like to have the area under their boat docks dredged should be prepared to contract directly with Energy Resources since this area is outside the City’s planned dredging zone. Private dredging will not be allowed deeper than the permitted depth of -6.0’ MLW (-6.4’ NGVD 29). Energy Resources has been instructed that this private work must be completed concurrently with the canal dredging, so it will be very important for property owners who desire the additional dredging to reach separate agreement with Energy Resources to perform the work prior to completing work within their canal.
We appreciate your help and support through the design permitting and bidding process. We will continue close communication with the East Naples Bay Advisory Committee, and all property owners associations to ensure this project is completed successfully.

The City Dock will no longer offer free dockage from vessels that are misplaced due to the dredging. The City Dock will offer dockage for $1.75 per foot per night for a slip, no restrictions on length of stay, or $10 per night for a mooring ball with a maximum 4 nights stay.


Dredging Paths

These pictures show how the path of the dredge will affect local boaters and their docks. Please move boats out of the way when required so we can complete this project on schedule.

 

Most Recent Status Updates

ROCK CAUTION: While rock removal is occurring in your canal, the controlling depth cannot be guaranteed to -5.0'MLW until construction is complete. The rock removal process causes rock to be broken and moved underwater, of which all will be removed once the canal is surveyed and completed. The City/Engineer/Contractor advise boaters to relocate their boat during the construction or keep your boat docked until the construction is complete in your canal (which may take several weeks).

August 01, 2012

Rock removal continues in Canal V-V (between Chesapeake and Jewel Box). Dry dredge material continues to be trucked to the Collier County Landfill from the dewatering area.

July 24, 2012

Rock removal in Canal R-R completed. Rock removal in Canal V-V (between Jewel Box and Chesapeake) will begin today. Please note that during rock removal, the rock barge will take up the width of the canal and the mouth of the canal will be closed off with a turbidity curtain. Please keep your boat docked or at a different location during the rock removal as to avoid any construction equipment and broken rock in the canal during the removal process.

July 17, 2012

Rock removal in Canal M-M completed today. Rock removal in Canal R-R (between Jewel Box and Dolphin/Bonita) will begin tomorrow. Please note that during rock removal, the rock barge will take up the width of the canal and the mouth of the canal will be closed off with a turbidity curtain. Please keep your boat docked or at a different location during the rock removal as to avoid any construction equipment and broken rock in the canal during the removal process. Canal V-V will be started around 7/23.

July 12, 2012

Rock removal in Canal CC-CC completed. Rock removal in Canal M-M (between Marlin and Dolphin/Bonita) will begin tomorrow. Please note that during rock removal, the rock barge will take up the width of the canal and the mouth of the canal will be closed off with a turbidity curtain. Please keep your boat docked or at a different location during the rock removal as to avoid any construction equipment and broken rock in the canal during the removal process.

July 2, 2012

Rock removal in Canal DD-DD has been completed today. Rock removal will begin at the mouth to Canal CC-CC tomorrow, July 3. There will be no work on Wednesday July 4th in observance of the holiday.

June 29, 2012

Rock removal in Canal A-A has been completed today. Canal DD-DD will finalize rock removal on Monday July 2. The following canals will see rock removal between July 3 and August 8: CC-CC, V-V, R-R, and M-M. These are the final four canals to complete the rock removal for the East Naples Bay Dredging Project. Please note that during rock removal, the rock barge will take up the width of the canal and the mouth of the canal will be closed off with a turbidity curtain. Please keep your boat docked or at a different location during the rock removal as to avoid any construction equipment and broken rock in the canal during the removal process.

June 7, 2012

Sediment dredging complete and the hydraulic dredge and pipeline has been demobilized from all of the canals. Only rock removal work remains to complete project. Canal A-A (between Snook and Sheepshead) punchlist items will be completed this week.

To complete the project, additional rock removal in the following canals will be completed in the upcoming weeks:

DD-DD
CC-CC
V-V
R-R
M-M

May 14, 2012

Rock removal in Canal W-W (between Blue Point and Chesapeake) is scheduled to begin at 9 am on Monday May 21, 2012. Notices of dredging have been attached to pilings whose boats will need to be relocated or tied closer to the dock so the rock barge can maneuver past. The rock removal may take up to 2 weeks. During this time, you will not be able to maneuver around the barge since it will take up the width of the canal. Please assist the dredge operation by clearing the water to allow the barge access.

May 10, 2012

The hydraulic dredge will be addressing high spots in Canals X-X and Z-Z in the upcoming days.

May 8, 2012

The hydraulic dredge will be addressing a high spot in canal R-R (south side of Jewel Box) over the next several days. The rock and mechanical dredge crew is working in Canal A-A to address any spots the preliminary survey indicated.

The final phase of the project will be rock removal in the following canals over the upcoming weeks: 

• DD-DD
• CC-CC
• W-W
• V-V
• R-R
• M-M

When the contractor is working, the canal will be closed off with a turbidity curtain and you will not have access in or out of the canal. During this time, you should relocate your boat out of the canal so the contractor can have access to the canal.
