  • Corps awards $7.7 million contract for habitat restoration in Upper Pool 4

    The U.S. Army Corps of Engineers, St. Paul District, awarded a $7.7 million contract to LS Marine, Inc., of Inver Grove Heights, Minnesota, Sept. 26, 2022, to use dredged material, or river sand, from the head of Lake Pepin to restore backwater river habitat near Bay City, Wisconsin.

  • Mohawk Northeast seeks permit for proposed work in Thames River in New London, Conn.

     The U.S. Army Corps of Engineers, New England District received a permit application to conduct

  • Norfolk Harbor deepening project advances with critical contract award

    On the heels of the Bipartisan Infrastructure Law earlier this year, the Norfolk Harbor and Channels Improvement Project’s federal sponsor, Norfolk District, U.S. Army Corps of Engineers, announced more good news.

  • USACE seeks public comment for proposed maintenance dredging and material placement for the Miami Harbor Navigation Project

    The U.S. Army Corps of Engineers (USACE) seeks public comment for its proposed Finding of No Significant Impact (FONSI) and draft Environmental Assessment (EA) for maintenance dredging and dredged material placement for the Miami Harbor Navigation Project at Port Miami, in Miami-Dade County, Florida. Public comments must be received by Oct. 19, 2022 for consideration.

  • Systematic Beneficial Use of Dredged Sediments: Matching Sediment Needs with Dredging Requirements

    PURPOSE: This technical note (TN) will outline a framework to identify beneficial and cost-effective coastal beneficial use of dredged sediment (BUDS) projects. Creation of a BUDS framework that can be applied at scale will promote sustainable BUDS practices, facilitating the delivery of flood risk management, social, and environmental benefits while still fulfilling the US Army Corps of Engineers (USACE) navigation mission. This proactive forecasting approach uses multi-criteria decision analysis (MCDA) and optimization tools to balance tradeoffs between navigation dredging and BUDS goals over project-scale timespans. The proposed framework utilizes available tools to quantify ecological system evolution and current and future dredging needs to develop a systems-level approach to BUDS. Required data include current and future information on (1) existing and planned natural and created aquatic ecological systems, which may include natural and nature-based features (NNBFs), (2) dredging requirements and costs, and (3) aquatic system physical and environmental data.

  • Application of Clean Dredged Material to Facilitate Contaminated Sediment Source Control

    Abstract: Navigation channels, turning basins, and other US Army Corps of Engineers (USACE)–managed navigation infrastructure often serve as repositories for contaminated sediment from off-site sources. As much as 10% of the material that USACE dredges on an annual basis is contaminated such that it requires additional and more costly management (for example, rehandling and placement in managed confined disposal facilities). Presence of contaminated sediments constrain potential management options resulting in additional costs and opportunity loss from the inability to beneficially use the material. One potential solution is applying clean dredged material to stabilize and isolate contaminated sediment sources, preventing further transport and introduction to USACE-managed infrastructure. This document summarizes a comprehensive literature review of laboratory and field case studies relevant to using clean dredged material to isolate or stabilize contaminated sediments, focusing on the physical, chemical, and biological parameters critical to establishing its feasibility and long-term effectiveness. Potentially effective engineering control measures were also reviewed where erosion and site hydrodynamics are facilitating the transport of contaminated sediments to USACE-maintained navigation infrastructure. This literature review documents and summarizes those factors considered in establishing feasibility and long-term effectiveness of the approach as well as the applicable engineering tools employed and constraints encountered.

  • 9,200 buckets later, Corps dredging halfway complete at Gold Beach

    A giant bucket – the size of a 1970s Volkswagen bus – swings through the air after it gobbles up 20 cubic yards of gravel blocking (shoaling-in) access to parts of the Port of Gold Beach, Ore. The small community on the southern coast, where the Rogue River meets the Pacific Ocean, doesn’t have much, but it has a port that sees upwards of 35,000 visitors per year for jet boat tours and averages 75-100 fishing boats a day, according to port officials.

  • $11.8 million River Contract awarded, need for repetitive dredging decreased

    The Memphis District awarded a contract to perform dike construction and maintenance at Donaldson Point, near New Madrid, Missouri (River Mile 903),  Aug. 24, 2022.  The Corps is partnering with Commercial Towing Interests, represented by the Lower Mississippi River Committee (LOMRC), to execute this $11,809,760 funded project. “This work is needed in this reach of the river due to continued navigation concerns raised by towboat pilots during recent low water years," said Project Manager Zach Cook. "This area has also required repetitive dredging over the past few years as well.” The funds provided for the work are a combination of Disaster Relief Supplemental Act of 2022 (DRSAA) and Infrastructure Investment and Jobs Act (IIJA) money allocated by Congress earlier this year.

  • Dredging to being at Sandusky Harbor: Notice to all boaters

    The U.S. Army Corps of Engineers, Buffalo District awarded a $1,372,000 contract to Michigan-based Luedtke Engineering to conduct dredging of the federal navigation channel in Sandusky Harbor and will begin on September 18 through mid-October.
