When enforced, only attending vessels and those vessels specifically authorized by the Fifth Coast Guard District Commander, or a designated representative, are permitted to enter or remain in the temporary safety zones. Each of the 179 temporary safety zones will be enforced individually, for a period lasting approximately 48 hours, as construction progresses from one structure to the next.\n\nSee Dominion Energy Monthly Mariner's Update for all activity. https://safe.menlosecurity.com/https://coastalvawind.com/resources.aspx\n\nAll offshore construction activities are weather dependent and may be pushed out due to projected weather conditions.\n \nF/Vs NOREEN MARIE and PONTOS will be providing safety vessel duties in the wind energy area and the export cable corridor and can be hailed on CH 16 24/7.

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":29090,"geometry":{"type":"Polygon","coordinates":[[[-89.82653999999997,29.81582000000003],[-89.87422999999995,29.800260000000037],[-89.87403999999998,29.779900000000055],[-89.82997999999998,29.789500000000032],[-89.80174999999997,29.786190000000033],[-89.79087999999996,29.776090000000067],[-89.78953999999999,29.776920000000075],[-89.79277999999994,29.781720000000064],[-89.78305999999998,29.778580000000034],[-89.77561999999995,29.79314000000005],[-89.81242999999995,29.810850000000073],[-89.82653999999997,29.81582000000003]]]},"properties":{"ESRI_OID":29090,"MSI_UID":29090,"ATU":8,"TITLE":"Breton/Chandeleur Icw Alternate Route - Mississippi River Gulf Outlet/General/Marine Construction (Excluding Bridges)/Dredging","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Marine Construction (Excluding Bridges)","TYPE":"Dredging","WTRW_UID":100116384886,"MRN":"urn:mrn:iala:wwy:us:navIV:dis8:secneworlexcecozon:secneworltersea:secneworlsublanact:breicwaltrou:misrivgulout","WATERWAY_NAME":"Mississippi River Gulf Outlet","CREATE_DATE":1758816707000,"MODIFIED_DATE":1773337720000,"BEGIN_DATE":1726704000000,"END_DATE":1777679999000,"DESCRIPTION":"Lake Lery - Bayou Lery - Dredge Operation --- From: 2024-09-19 To: 2026-04-30 --- The Dredge LILLIE is conducting dredging throughout Lake Lery.

Mariners are advised to transit west of the construction area. Vessels transiting near the work zone should proceed with extreme caution, operate at their slowest safe speed, and maintain a minimum 200 ft buffer from all structures and barges. 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 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 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 Posillico Civil. Within this jobsite, Posillico Civil is conducting marine construction for the Manhattan Tunnel Project to stabilize the ground beneath the Manhattan bulkhead in preparation for tunnel boring. Work hours are approximately 7AM – 7PM, Monday through Sunday. Equipment on scene includes aluminum work skiffs, 155’ x 40’ Scow “Angela,” and a 150’ x 69’ Work Barge “JFB 4550” with Liebherr LR1300 Crane. VHF-FM Channel 13 / 16 / 64. Within both jobsites, 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.
