  • Albeni Falls Dam Officials Announce 2021 Recreation Season Openings

    U.S. Army Corps of Engineers’ officials announced today that the 2021 Albeni Falls Dam recreation season will begin May 8 with the opening of Riley Creek Recreation Area. Springy Point and Priest River “The Mudhole” Recreation Areas will open for the season May 15. Albeni Cove Recreation Area is closed for the 2021 season while the campground and day-use area are used to stage materials for Strong’s Island bank stabilization work. Trestle Creek Recreation Area opened April 1.

  • VIDEO Prado Basin Ecosystem Restoration, Chief's Report

    On April 22, Earth Day, Lt. Gen. Scott Spellmon, the 55th Chief of Engineers, signed a Chief’s Report, which recommends a multi-year, multi section plan to tackle loss and/or degradation of aquatic, riparian woodland and floodplain habitats along the Santa Ana River due to numerous issue the waterway has experienced since the 1940s.

  • Jacksonville District hosts media day

    CLEWISTON, Fla. (April 14, 2021)—The U.S. Army Corps of Engineers Jacksonville District hosted its first-ever media day by inviting media from across the region to learn about projects, mission, and completion dates for south Florida projects including the rehabilitation of Herbert Hoover Dike and Lake Okeechobee.

  • Avenue 146 still closed at Success Lake

    SACRAMENTO, Calif. – The U.S. Army Corps of Engineers Sacramento District is continuing construction

  • U.S. Army-delivered helipad projects at hospitals in Croatia to hasten emergency medical care and save lives

    The U.S. Army Corps of Engineers is delivering three modern helicopter landing zones at hospitals across Croatia to help reduce transportation times in emergency situations and ultimately save lives. The helicopter landing zone projects are funded through the United States European Command, or EUCOM, and are being delivered in close coordination with the U.S. Embassy in Zagreb.

  • Army Corps constructs beach access with innovative flood barrier in Seaside Heights

    The U.S. Army Corps of Engineers and its contractor completed construction of a vehicular access in Seaside Heights, NJ where the beach meets the boardwalk at Grant Avenue. The access includes a removable coastal flood barrier, which can be quickly installed prior to a storm. The vehicular access and removable barrier are part of the 14-mile dune and beachfill project along the Barnegat Peninsula in Ocean County, NJ.

  • Camp Perry Historic District Landscape Inventory and Viewshed Analysis

    Abstract: The National Historic Preservation Act of 1966 (NHPA) established the National Register of Historic Places (NRHP), which requires federal agencies to address their cultural resources, defined as any prehistoric or historic district, site, building, structure, or object. NHPA section 110 requires federal agencies to inventory and evaluate their cultural resources. Section 106 requires them to determine the effect of federal undertakings on properties deemed eligible or potentially eligible for the NRHP. Camp Perry Joint Training Center (Camp Perry) is located near Port Clinton, Ohio, and serves as an Ohio Army National Guard (OHARNG) training site. It served as an induction center during federal draft periods and as a prisoner of war camp during World War II. Previous work established boundaries for an historic district and recommended the district eligible for the NRHP. This project in-ventoried and evaluated Camp Perry’s historic cultural landscape and outlined approaches and recommendations for treatment by Camp Perry cultural resources management. Based on the landscape evaluation, recommendations of a historic district boundary change were made based on the small number of contributing resources to aid future Section 106 processes and/or development of a programmatic agreement in consultation with the Ohio State Historic Preservation Office (SHPO).

  • AIS Data Case Study: Selecting Design Vessels for New Jersey Back Bays Storm Surge Barriers Study

    Abstract: The purpose of this Coastal and Hydraulics Engineering technical note (CHETN) is to describe how historic Automatic Identification System (AIS) vessel position data were used to identify a design vessel for use in a storm surge barrier design study. Specifically, this CHETN describes how the AIS data were accessed, how the universe of vessel data was refined to allow for design vessel selection, and how that selection was used in a storm surge barrier (SSB) study. This CHETN draws upon the New Jersey Back Bays Coastal Storm Risk Management Feasibility Study (USACE-NAP 2019), specifically the Appendix B.2 Engineering Appendix Civil document1. The New Jersey Back Bays Study itself builds upon the work of the North Atlantic Coast Comprehensive Study (NACCS) initiated after Hurricane Sandy in 2012 (USACE 2015a).

  • Houston Ship Channel Expansion Channel Improvement Project (ECIP) Numerical Modeling Report: Increased Channel Width Analysis

    Abstract: The Houston Ship Channel is one of the busiest deep-draft navigation channels in the United States and must be able to accommodate larger vessel dimensions over time. The U.S. Army Engineer District, Galveston (SWG) requested the U.S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory perform hydrodynamic and sediment modeling of proposed modifications along the Houston Ship Channel. The modeling results are necessary to provide data for salinity and sediment transport analysis as well as ship simulation studies. SWG provided a project alternative that includes channel widening, deepening, and bend easing. After initial analysis, two additional channel widths in the bay portion of the Houston Ship Channel were requested for testing. The results of these additional channel widths are presented in this report. The model shows that the salinity does not vary significantly due to the channel modifications being considered for this project. Changes in salinity are 2 parts per thousand or less. The tidal prism increases by less than 2% when the project is included, and the tidal amplitudes increase by no more than 0.01 meter. The residual velocity vectors do vary in and around areas where project modifications are made.
