This is an impoundment depth map document supporting a water management renovation project for Pocotaligo Preserve - Phase II, managed by Beaufort County's Land Preservation Department in Yemassee, South Carolina. The depth map provides critical site information for contractors bidding on the water management renovations, which include installation of corrugated aluminum pipes with flap gates, a new rice trunk structure, dike retopping of approximately 810 linear feet, repair of a dike break, installation of additional drainage pipes, excavation of circulation canals, and replacement of existing concrete pipes. The project requires approximately 115 cubic yards of dike material, 1,080 cubic yards of cross-dike fill, and 2,890 cubic yards of berm fill. A non-mandatory pre-proposal meeting and site visit are scheduled for September 2 and 3, with proposals due September 17, 2026. Contractors must provide all equipment, materials, manpower, and transportation, maintain designated construction and staging areas with safety fencing, and complete work during dry conditions with a one-year warranty.

Evaluation of proposals is qualifications-based with pricing weighted at 15 percent of the total evaluation score, while understanding of scope and goals comprises 25 percent, approach and project methodology comprises 30 percent, and experience with similar projects and references comprises 30 percent. Individual task costs are assessed against budget thresholds, and tasks may be removed if costs exceed available funds. Contractors must carry workers' compensation insurance, general liability coverage of $1 million per occurrence and $2 million aggregate, automobile liability of $500,000, umbrella liability of $2 million, and professional liability of $1 million. Proposals must remain firm for 90 days from the closing date and must comply with Title VI nondiscrimination requirements and South Carolina state law. The County has already obtained a Managed Tidal Impoundment General Permit from the U.S. Army Corps of Engineers, with any additional permitting to be completed by the County and its management consultant.
