Work to be completed under this contract consists of dredging a sand trap and a portion of the rubble spoil shoal and disposal of the dredge material in the Port Everglades Harbor Ocean Dredged Material Disposal Site (ODMDS). Dredging operations are anticipated to commence on October 22, 2025, and will take place 24 hours a day, 7 days a week. With an estimated completion date of July 18, 2027. The DREDGE 54, along with DREDGE NEW YORK which will start on or about December 18, 2025, are planned to collectively dredge more than 400,000 CY of material from the north side of the Port Everglades entrance channel, immediately seaward of the north jetty and beach north of the inlet. The dredges would appreciate slow bell passing.\n\nWhile approaching the jetty dredging work area location. The material will be placed into scows and towed to the Port Everglades Harbor ODMDS, which is located approximately 3.1 nautical miles northeast of the entrance to Port Everglades Channel, outside of State Waters. \n\nThere is a project tow route between Red Buoy 2 and the ODMDS CenterPoint. Fishermen and trawlers should be aware of limited mobility for tug and scow transits. Small-Vessel Captains should take caution to avoid passing between the scow and towing tug while under transit. While not always visible at a distance, there is a large steel-tow cable that passes between the bow of the scow and the stern of the towing tug. The survey vessel, Pearl River, will conduct survey operations of the ODMDS disposal area and work area corridors (during daylight hours/7 days per week). A crew transfer vessel, the Cooper River, will transfer crew between the shoreside boarding location at Bahia Mar Yachting Center and the dredging equipment. \n\nDisposal Location: \n26.1315693N / 080.0333404W\n26.1315700N / 080.0305700W\n26.1211186N / 080.0305709W\n26.1211207N / 080.0333410W\n\nDredging Location:\n26.0942747N / 080.1060199W\n26.0945457N / 080.1057116W\n26.0947778N / 080.1053881W\n26.0947770N / 080.1049664W\n26.0948133N / 080.1046524W\n26.0948637N / 080.1045246W\n26.0949547N / 080.1044314W\n26.0952883N / 080.1040902W\n26.0954573N / 080.1040690W\n26.0969380N / 080.1038831W\n26.0969390N / 080.1040363W\n26.0977375N/ 080.1039367W\n26.0977215N / 080.1013560W\n26.0961361N / 080.1013842W\n26.0961403N / 080.1020684W\n26.0958314N / 080.1022291W\n26.0953104N / 080.1022933W\n26.0949923N / 080.1025778W\n26.0949941N / 080.1028349W\n26.0943524N / 080.1027938W\n26.0942799N / 080.1052630W","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-80.02404,26.13687],[-80.03079,26.1367],[-80.03081,26.12263],[-80.10443,26.09771],[-80.10486,26.09498],[-80.10536,26.09489],[-80.10574,26.09391],[-80.09832,26.09397],[-80.03015,26.12023],[-80.02377,26.1201],[-80.02404,26.13687]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}},{"type":"Feature","id":30406,"geometry":{"type":"Polygon","coordinates":[[[-96.79658999999998,28.306130000000053],[-96.79822999999999,28.304770000000076],[-96.80268999999998,28.30054000000007],[-96.80834999999996,28.295700000000068],[-96.80972999999994,28.292070000000024],[-96.80955999999998,28.287240000000054],[-96.80543999999998,28.281340000000057],[-96.79993999999994,28.27681000000007],[-96.79839999999996,28.275600000000054],[-96.79839999999996,28.27091000000007],[-96.79598999999996,28.26532000000003],[-96.78878999999995,28.257750000000044],[-96.78697999999997,28.249850000000038],[-96.78311999999994,28.245130000000074],[-96.77779999999996,28.24264000000005],[-96.76767999999998,28.249670000000037],[-96.79101999999995,28.26947000000007],[-96.79315999999994,28.27771000000007],[-96.80028999999996,28.28421000000003],[-96.80302999999998,28.29170000000005],[-96.79375999999996,28.299930000000074],[-96.79658999999998,28.306130000000053]]]},"properties":{"ESRI_OID":30406,"MSI_UID":30406,"ATU":8,"TITLE":"Victoria West Entrance Channel - San Antonio Bay/General/Marine Construction (Excluding Bridges)/Facilities, Barriers, Manmade Reefs, Riprap, Jetties/Dikes","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Marine Construction (Excluding Bridges)","TYPE":"Facilities, Barriers, Manmade Reefs, Riprap, Jetties/Dikes","WTRW_UID":100116384820,"MRN":"urn:mrn:iala:wwy:us:navIV:dis8:seccorchrexcecozon:seccorchrtersea:seccorchrsublanact:matshicha:matbay:poroconcha:poroconlan:viceasentcha:vicwesentcha:sanantbay","WATERWAY_NAME":"San Antonio Bay","CREATE_DATE":1760556436000,"MODIFIED_DATE":1773942340000,"BEGIN_DATE":1760486400000,"END_DATE":1786924799000,"DESCRIPTION":"San Antonio Bay - Rock Dike Construction --- From: 2025-10-15 To: 2026-08-15 --- Foreshore rock dike construction is being conducted in San Antonio Bay, along the southwest shoreline of the Aransas National Wildlife Refuge.

The USCG has established a Safety Zone, 33 CFR 165.T01-0336 Safety Zone; Hudson River, Manhattan, NY. Mariners transiting west of the safety zone should proceed at a speed to minimize potential wake or surge damage to the vessels working the construction area. There are two distinct jobsites within the construction area. The first jobsite, which is operated by Weeks Marine, is west of Pier 66. Within this jobsite, Weeks Marine is conducting soil mixing within a 110’ wide x 600’ long cofferdam for the Hudson River Ground Stabilization (HRGS) Project. Work hours are approximately 7AM – 7PM, Monday through Saturday. The cofferdam is marked with FL W 4s lights at each corner and at 30 ft intervals, and with white retro-reflective tape 6” high and at least 4’ long is installed above the MHHW mark every 50 feet on the cofferdam.  The Weeks 61 barge (AIS - WEEKS 61 Barge) will move between the south and north sides of the cofferdam to excavate spoils within the cofferdam.  The Weeks 61 barge monitors VHF-FM channels 13 / 16 / 82.  The Weeks 263 barge (AIS- WEEKS 263) and material barges will be on the southern side outside of the cofferdam to support drilling operations within the cofferdam. The Weeks 263 barge monitors VHF-FM channels 13 / 16 / 67.  The Weeks 526 barge (AIS - WEEKS 526) will remove piles from the west end, lay them down on barges, shift east, and reinstall them.  The Weeks 526 barge monitors VHF-FM channels 13 / 16 / 66.  The second jobsite, which is north of Pier 66 in close proximity to the Manhattan bulkhead and near position 40-45-15.270N, 074-0-28.007W, is operated by Frontier-Kemper Tutor Perini JV. Within this jobsite, Posillico Civil has constructed a 200 ft x150 ft temporary marine structure to facilitate grouting and freezing operations to stabilize the ground beneath the Manhattan bulkhead in preparation for tunnel boring. All barges require tug assistance for a movement and a minimum notice of 24 hours via VHF radio is required for any barge relocation. All moored barges display fixed white lights in accordance with the Inland Navigation Rules. Four seasonal white lighted buoys have been reset. Two (LLNR 37663, 37663.1) are upriver of the construction area, and two (LLNR 37663.2, 37663.3) are downriver. All four lighted buoys exhibit FL W 2.5s characteristics.  From July 1, 2026, to July 31 and September 1 to September 30, Normandeau Associates, Inc. will be on site within the Safety Zone conducting monitoring for Atlantic and shortnose sturgeon.  As part of this monitoring activity, the vessel Parker will be on scene.  Work hours are approximately 7AM – 7PM, Monday through Saturday.

Operations are expected to begin on July 19, 2026, and be completed by October 12, 2026. Dredging of the Salem River will take place between Salem River Entrance Channel Lighted Buoy 2 (LLNR 2645) and Salem River Channel Light 13 (LLNR 2713). The submerged pipeline will run directly from the Salem River to Supawna Meadows National Wildlife Refuge. All vessel traffic is requested to contact the dredge on VHF channel 13 or 16 prior to passage. For emergencies the Dredge Rockbridge can be reached at (757) 635-2576.\nAll mariners are requested to stay clear of the dredge, pipelines, barge, derricks and operating wires about the dredge. All operators should be aware that the dredge and pontoon lines are held in place by cables, which are attached to anchors some distance from the dredge and pontoons. Buoys are attached to the anchors so that they may be moved as the dredge moves. Submerged lines should be avoided. Mariners are requested to exercise extreme caution when approaching, passing, and leaving the dredging plant. The dredge Rockbridge monitors VHF channels 13 and 16.
