Baltimore Harbor Anchorages and Channels Modification of Seagirt Loop Channels, Maryland Feasibility Study

The study conducted pursuant to this authority resulted in a Chief’s Report dated June 8, 1998, and in project authority in §101(a)(22) of the Water Resources Development Act (WRDA) 1999 (Pub. L. No. 106-53). As discussed in the Chief of Engineer’s Report, the project included improvements to access channels serving the public terminals of Dundalk, Seagirt, and South Locust Point. The federal government assumed maintenance of these channels at their authorized depth. Note that §101(a)(22)(i) mentions deepening an access channel to the Dundalk Marine Terminal to 50 feet that was not accomplished. 

The USACE Baltimore District and MDOT MPA will conduct a feasibility study to evaluate the advisability of modifications to the Seagirt Loop channels, which include the West Dundalk Branch Channel, the Dundalk-Seagirt Connecting Channel, and the Seagirt West Branch Channel, to accommodate the increased post-Panamax vessel traffic at the Seagirt Marine Terminal. The feasibility cost-sharing agreement (FCSA) between USACE and MDOT MPA was executed on September 22, 2020. The agreement between USACE and MDOT MPA formally begins a study of improvements to the Seagirt Loop channels. The feasibility study will comply with the USACE SMART Planning Milestones for a 3x3 study (policy requirement to complete the study in three years for less than $3 million). The study will be conducted in four segments:

  • Segment 1: Scoping and Alternatives Analyses
  • Segment 2: Tentatively Selected Plan
  • Segment 3: Agency Decision and Draft Report
  • Segment 4: Detailed designs and final Report Preparation

Study Purpose and Goals

Since completion of the Baltimore Harbor Anchorages and Channels (BHAC) Study (1998), which resulted in the construction of significant navigation improvements to Baltimore Harbor anchorages and access channels, the future with project conditions projected in the study have significantly changed as a result of worldwide fleet shifts towards these larger container vessels.

The U.S. Army Corps of Engineers (USACE) and the Maryland Port Administration (MPA), a division of the Maryland Department of Transportation (MDOT), are conducting a feasibility study to determine the advisability of modifications to the BHAC, including for the Seagirt Loop channels that serve the Seagirt Marine Terminal, the destination for a majority of container traffic in the Port. The objective of the study is to identify one or more solutions that can safely accommodate the projected increase in post-Panamax vessels calling at the Port.  

The overall goal of the study is to affirm, reformulate, or modify the BHAC authority by recommending actions that meet the changed current and future conditions at Baltimore Harbor and the Port facilities. The study objectives are to develop solutions that:  

  • Decrease transportation delays to vessels calling at the Port.
  • Improve navigability and increase safety for vessels using the Seagirt Loop channels. 
  • Meet current and forecasted future capacity needs for container traffic at the Port.

 Was the public provided an opportunity to participate in this process?

USACE and MDOT MPA held a virtual public meeting on Thursday, February 24, 2022  to present the report and receive comments.

 How was this study funded?

This $3 million study is split evenly between the Army Corps through Congressional funding and the Maryland Port Administration, the non-federal sponsor.

 What is this study?

The USACE Baltimore District conducted a feasibility study to evaluate the advisability of modifications to the Seagirt Loop channels, which include the West Dundalk Branch Channel, the Dundalk-Seagirt Connecting Channel, and the Seagirt West Branch Channel, to accommodate the increased post-Panamax vessel traffic at Seagirt Marine Terminal. The overall goal of the study was to affirm, reformulate, or modify the Baltimore Harbor Anchorages and Channels study authority by recommending actions that meet the changed current and future conditions at Baltimore Harbor and the Port facilities. The study objectives are to develop solutions that:

  • Decrease transportation delays to vessels calling at the Port.
  • Improve navigability and increase safety for vessels using the Seagirt Loop channels.
  • Meet current and forecasted future capacity needs for container traffic at the Port.
 Why was this study necessary?

To promote safe and efficient navigation in the Seagirt Loop channels. Post-Panamax container vessels make regular calls to the Port. Inefficiencies in transit, due to insufficient channel width at turns, are evident as vessels transiting to or from Seagirt berths 1-3 must proceed with great caution to avoid collisions or allusions (the running of one ship into a stationary ship) while berth 4 is occupied with a large vessel.  Berth 4 can accommodate new-Panamax container ships (draft to 50 feet and 22 container width) and improvements to Berth 3 will also accommodate similar sized vessels. Furthermore, vessels with a draft in excess of 42 feet must be backed out of the berthing areas, or turned.
