Construction of the Raccoon Island Restoration project within state-owned waters. This project is an environmental restoration project to create beach and marsh habitat which includes dredging and placement of approx.2,915,000 cubic yards (in-place volume) of fill borrowed from the Ship Shoal Block 88 borrow area in the Gulf of America. The project involves placing approx. 1,335,000 CY of sand fill along 1.45 miles of shoreline to establish a dune crest at +8 feet NAVD88, with a variable width of 200 to 315 feet. Additionally, approx. 1,580,000 cubic yards of sand will be used to develop a 227-acre marsh footprint featuring three central mounds at +6.0 feet NAVD88. Structural improvements for the project include the repair of 16 gulfside breakwaters using approximately 7,500 tons of armor stone. Additionally, the project prioritizes the comprehensive repair and extension of the existing terminal groin by 300 feet, which will require approximately 7,200 tons of armor stone. Finally, 13 bayside shoreline protection structures will be constructed using approx. 10,000 tons of foundation stone, approx. 40,800 tons of armor stone, and approx. 17,000 tons of oyster cultch. Additional work includes construction of two tidal channels through the created marsh footprint and along the edge of the existing marsh; excavation of temporary flotation access channels; installation of 14 settlement plates; daily bird observations and bird abatement; supply and placement of approximately 10,400 haybales; vegetation plantings; completion of pre-construction and post-construction surveys, including but not limited to topographic, bathymetric, and magnetometer surveys. To qualify for this project, the contractor must demonstrate ownership of equipment—or provide documentation of a joint venture/teaming arrangement—that meets specific operational standards. The equipment must hold American Bureau of Shipping (ABS) and/or U.S. Coast Guard (USCG) dredge certifications for open-water operations in the Gulf of America, seaward of the COLREGS line. Additionally, the equipment must be capable of hydraulically placing at least 20,000 CY of sand within a 24-hour period.
