About this file
This is a Project Description and Cover document for a maintenance dredging project prepared by Baskerville-Donovan, Inc. for Santa Rosa County, Florida. The Santa Rosa County Board of County Commissioners is soliciting sealed bids from properly licensed and insured marine contractors for the Archie Glover Channel Maintenance project, with specifications available through the Santa Rosa County Procurement Portal. The project involves hydraulic maintenance dredging of approximately 5,100 cubic yards of material along the Santa Rosa Channel navigation corridor, which connects Mullatto Bayou/Archie Glover Boat Ramp to Escambia Bay. Additional work includes construction of a spoil cell with erosion and turbidity control measures, removal and replacement of 8 existing wooden piling-supported Private Aids to Navigation per U.S. Coast Guard Light List coordinates, removal of unsuitable materials from the site, and restoration of the spoil cell site to preconstruction conditions. The dredging elevation target is -5.5 NAVD88 with a channel bottom width of 30 feet. Questions concerning the request must be submitted through the procurement portal by 12:00 p.m. on Wednesday, February 11, 2026. All proposals must be submitted through the procurement portal by 10:00 a.m. on Monday, February 23, 2026, at which time bids will be publicly opened via Microsoft Teams.
The project specifications require that dredging operations utilize hydraulic processes with dewatering means and methods to be solely determined by the contractor, subject to permit and environmental requirements. Dredged material must be substantially dried prior to removal from the site and shall not be disposed of or utilized within any water body. A floating turbidity barrier must be deployed at the discharge hose end with monitoring to ensure turbidity readings do not exceed federal, state, and local requirements. Silt fences with hay bales must be installed around the spoil cell perimeter prior to dredging operations commencement and maintained throughout the project period. Santa Rosa County encourages participation from all business community segments, including small businesses, minority/women-owned businesses, and disadvantaged business enterprises. The County reserves the right to waive bid irregularities, reject any or all bids for documented reasons, and award the contract to the bid determined to be in the best interest of Santa Rosa County. Pricing terms, contract award date, and contract term information are not specified in this project description document.

SANTA ROSA COUNTY CHANNEL
MAINTENANCE
Prepared For:
Santa Rosa County, FL
Prepared By
Baskerville-Donovan, Inc.

Pensacola, FL 32502
October 2024
Project Description
This project is a maintenance dredge project for Santa Rosa County. The navigation channel of interest is Santa Rosa Channel as identified on US Nautical Charts and the US
Light List (Volume IV). The channel connects Mullatto Bayou / Archie Glover Boat
Ramp to Escambia Bay. The proposed dredging operations will return the navigation channel to the previously permitted depth and width. The dredging elevation is -5.5
NAVD88 (-5.83 MLWL) and the channel bottom width of 30 feet. The work also includes the replacement of 8 existing wooden piling-supported Private Aids to
Navigation along the access channel based on U.S. Coast Guard Light List coordinates.
The existing Private Aids are currently dated, damaged, or missing.
The dredging operations are to be conducted using hydraulic processes. The basis of design depicted in the project plans utilizes a settling basin configuration. However, the means and methods of dewatering the dredge material and the dredge material maintenance area (DMMA) will be the sole responsibility of the contractor and shall utilize the general upland areas shown in the plans and shall meet permit and environmental requirements.
Material shall be substantially dried prior to removal from the site as to not leach from containers along the roadways or rights-of-way. A floating turbidity barrier shall be deployed at the end of the discharge hose and dewatering discharge shall be monitored to ensure NTU readings do not exceed those required by federal, state, and local requirements. The contractor is solely responsible for recharging or returning water from the spoil cell. The dredge material maintenance area will have silt fence with hay bales around the perimeter. Dredging operations shall stop when the water level in spoil cell rises 18” from the top of berm. The dredged material shall remain within the spoil cell until the material is adequately dewatered. The dredge material shall be hauled off site and not deposed or utilized within any water body. The dredge material is intended to be placed on public property and for public purposes.
Best management practices will be utilized during construction to minimize the potential for erosion and sedimentation. Silt fences will be installed at the limits of the dredge material maintenance area prior to the start of dredging operations. The erosion control facilities shall be maintained throughout the dredging period and until final dredging depths are achieved and approved by the engineer.
A. General: Project name is Santa Rosa County Channel Maintenance
B. Briefly and without force and effect upon the contract documents, the work of the
Contract can be summarized as follows:
1. Construct a spoil cell and to receive dredge material and install necessary turbidity/erosion control measures.
2. Perform hydraulic maintenance dredging of approximately 5,100 cubic yards of material along the navigation channel of Santa Rosa County
Channel.
3. Remove unsuitable materials from the site and legally dispose of.
4. Remove and/or Replace 8 existing channel markers along Santa Rosa
County Channel at coordinates listed in the USCG Light List.
C. The work includes but may not be limited to the following:
1. Place and maintain erosion control devices.
2. Place control and limits of construction markers.
3. Create spoil cell adjacent to dredge site as shown in the plan set.
4. Maintain a navigable passage for vessels.
5. Remove unsuitable materials from the site.
6. Provide labor and materials for replacement of channel markers.
7. Provide testing, means and methods necessary to prevent sediment from leaving the site or exceeding allowable tolerances.
8. Return spoil cell site and adjacent easements to preconstruction conditions.
