| dc.description.abstract | The purpose of the project is to continue to maintain safe and efficient vessel navigation through the Federal channel. The accumulation of sediment, commonly referred to as shoaling, within the limits of the Federal channel created the need to complete this project. The shoaling has reduced channel depths, hindering safe, efficient vessel navigation. Shoaling within these areas is spotty and is not one long contiguous shoal. Periodic dredging is required to remove accumulated sediments and thus maintain the channel to its federally authorized dimensions. This environmental assessment (EA) evaluates the periodic operations and maintenance (O&M) dredging of Reach 1 of the IWW in Broward County, the shoal in cuts P-59 to P-60 of Reach 4 of the IWW in Palm Beach County, and placement of dredged material in several different potential placement locations, depending on the quality and quantity of the dredged material, time of year, and funding. This EA also completes the required analysis under National Environmental Policy Act (NEPA). | en_US |
