  • Galveston District survey team conducts post dredge survey in Houston Shipping Channel

    USACE survey teams make a detailed map of the sea floor before a dredge operation to estimate the amount of material to be removed and after the dredge has completed work on the section to calculate and verify that the contract work was completed. If the dredge material is deposited offshore a survey team will make a third map of the sand added to the ocean floor.

  • Corps of Engineers to begin dredging, beach nourishment in South Haven

    The U.S. Army Corps of Engineers, Detroit District will begin hydraulically dredging the federal navigation channel and nourishing the South Haven Harbor shoreline next week. In coordination with the City of South Haven, the Corps of Engineers will dredge 57,300 cubic yards of material from the Black River Federal Channel. The tested-safe material will then be placed on South Haven’s public South Beach from the South Pier and extending 1,900 feet southward for beach nourishment.

  • Dredging in Grand Haven targeting mid-July completion

    Detroit -- The U.S. Army Corps of Engineers, Detroit District (USACE) is currently utilizing 24-hour dredging in Grand Haven, Michigan during favorable weather to remove shoaling blocking Grand Haven Harbor from commercial traffic. The project is expected to be completed in mid-July. Severe weather and minimal ice cover during the winter led to increased shoaling in several harbors on Lake Michigan this year, blocking large commercial vessel traffic. Grand River commercial docks are struggling to receive shipments due to the unexpected shoaling. The King Co., Inc. of Holland, Michigan is on-site and contracted to clear 141,000 cubic yards of sand from the federal channel at Grand Haven, just beyond the pierheads. The material will be placed 7,000 to 10,000 feet north of the north pier onto the beach and into the nearshore area between the Ordinary High-Water Mark (OHWM) and the most-landward 12 feet depth contour in the lake. The placement area borders the Ottawa County North Beach Park and several properties along North Shore Drive. The contract, awarded Feb. 28, required the work to begin in Holland and Grand Haven harbors when the weather allowed in the spring using hydraulic dredging for speed and cost. Unusually windy and wavy conditions during March and April delayed dredging work in Holland.

  • Advances in Dredged Material Evaluations for Inland and Ocean Aquatic Placement: Modernized Processes and Supportive Tools

    Abstract: As part of the US Army Corps of Engineers’ mission to evaluate and move dredged material (DM) to maintain navigation channels, environmental evaluation of the prospective material is required by the Code of Federal Regulations. While existing guidance manuals provide useful guidance to DM regulators, they are over 30 years old and not reflective of the latest science. However, efforts to update procedures and publish the documents individually or as a combined dredging manual have been thus far unsuccessful. These issues, coupled with a lack of consistent reporting and decision documentation, lead to delays arising from challenges addressing project-specific issues not clearly covered within the existing guidance, revisiting previously resolved issues or negotiating disputes between permitting authorities. This technical report provides a path toward modernization of the environmental compliance aspects of DM evaluation guidance in part through software executables guiding the management and decision process and through a structured, evidence-based approach. The value added is an updated approach to DM testing and evaluation decisions.
