Appendix_F_Wheatley_Reservoir_Bathy_Depths.pdf

This appendix document provides bathymetric depth data for Wheatley Reservoir in support of Charles County's dredging services procurement. The file contains survey information from bathymetric and sub-bottom profiling surveys conducted in late 2024 that identified significant sediment accumulation in the northern and eastern areas of the reservoir, which are designated as the focus areas for the initial dredging event. Qualified dredging contractors are invited to submit sealed bids to provide wet dredging, hauling, and sediment disposal or beneficial reuse services within these defined areas at Wheatley Dam reservoir. The dredging project is located at Gilbert Run Park, 13140 Charles Street, Charlotte Hall, Maryland 20622, a public park facility where dredging activities must be coordinated with park accessibility and ongoing activities. Contractors are encouraged to review the project documents and conduct site visits during normal business hours prior to submitting proposals. The volume of sediment to be dredged will be dependent upon the cost per cubic yard and other associated project tasks. Charles County reserves the right to request post-dredging bathymetric survey data from the selected contractor to document changes in reservoir elevation following the completion of dredging activities.

The appendix serves as a technical reference document supporting the bidding process and does not independently establish pricing terms, set-asides, or funding mechanisms. Interested contractors should consult the primary solicitation documents and project specifications for detailed information regarding bid submission requirements, evaluation criteria, contract award timeline, insurance and bonding requirements, and project funding sources. The bathymetric depth data contained in this appendix is essential for contractors to accurately estimate dredging volumes, develop realistic cost proposals, and plan logistical and equipment requirements for the project.
