The southeastern cell main dike footprint is being deepened to a required depth of -41 feet mean lower low water (MLLW). Also, the central and southern access channel footprints are being deepened to a required depth of -25 feet MLLW. Two feet of allowable over depth dredging will be part of the contract dredging pay prism for both the main dike and access channel footprints. A main dike footprint not to exceed depth of -46 feet MLLW will be observed for this project. A central and southern access channel footprints not to exceed depth of -30 feet MLLW will be observed for this project.
