JAXPORT conducts approximately 500,000 cubic yards of maintenance dredging annually. Historically, the port has relied on permanent placement of these materials within confined disposal areas constructed as a series of cells on islands in the St. Johns River. Over the years, these cells are beginning to fill, and JAXPORT faces a critical need to enhance dredged material capacity to support future maintenance operations. JAXPORT engaged Taylor Engineering to develop a design and seek permits to restore and expand capacity of Bartram Island Cell C. Work began with a detailed geotechnical evaluation of the site foundation conditions and stored dredged materials. Based on the results of the geotechnical analysis, Taylor Engineering developed a design to offload unsuitable dredged materials and mine the site for suitable materials to raise the containment dikes. Because transporting unsuitable material from the island is impractical, the design incorporated low-berm storage cells in the adjacent uplands on the Island to receive the unsuitable material. By beneficially reusing the suitable dredged materials, Taylor Engineering’s design raised the containment dike by 10 feet to elevation 32 feet. The design addressed challenging seepage and slope stability concerns using a stability berm, internal drains, and geotextile reinforcement. The project avoided wetland impacts and secured permits from the Florida Department of Environmental Protection. Taylor Engineering provided daily construction management and inspection, and with project completion, JAXPORT gained approximately 1,200,000 cubic yards of additional dredged material management capacity.
