Commercial Navigation 

Practice Overview

Section 203  and 204 Deep Draft Navigation Project

Port Canaveral, Florida 

Canaveral Port Authority

DMA managed and prepared the Section 203 (WRDA 86) and 204 Studies for navigation improvements (channel widening and deepening) at Port Canaveral, Florida, leading to completion of construction in 2016.  Port improvements were intended to serve the larger cruise ships and bulk cargo vessels calling at the Port now and in the future.  The Project began as a Section 203 Study, which received a positive recommendation to Congress and authorization in WRRDA 2014.  The immediate needs of the CPA required DMA to assist the CPA in reconfiguring the study as a Section 204 (f) project, which was approved by the USACE and constructed by Port Canaveral at non-Federal expense.  The Assistant Secretary of the Army agreed to Federal assumption of maintenance of the completed project.

DMA’s roles were Project Management, Plan Formulation, Feasibility Report Preparation, and NED Benefit/Cost Analysis, and Public Involvement.  Project management tasks performed by DMA included: identification and coordination of all necessary engineering, environmental, planning, and economic studies needed to meet USACE's requirements for a feasibility study.  Economic analysis tasks performed by DMA included: commodity and cruise projections, fleet forecasts, and calculation of with and without project transportation costs.  Plan formulation tasks included: development of without and with project conditions, formulation of alternatives, evaluation of alternative plans, and identification of the NED Plan. 

DMA also provided Port Canaveral with Corps policy compliance advice and assistance, and assisted the Port in conducting coordination with the Jacksonville District and Headquarters of USACE.  Our firm responded to Coprs of Engineers Agency Technical Review comments, prepared the presensation of District Engineer's briefing, prepared Civil Works Review Board conference briefing packages, and provided support to Port Canaveral during the Civil Works Review Board process.  In addition, DMA assisted with the planning and conducting of public meetings and resource agency meetings.

Economic Analyses for Navigation Improvements – Limited Reevaluation Report

New York and New Jersey Harbor

New York District, US Army Corps of Engineers

DMA performed the economic reanalysis of the New York and New Jersey Harbor Navigation deepening project as part of the Limited Reevaluation Report.  The 50+ foot deepening of the Federal channels in New York/New Jersey harbor is one of the largest commercial navigation projects in the nation.  Since DMA completed its feasibility phase effort in 2000 (see below), significant changes occurred at the Port of New York and New Jersey, most notably a much higher than anticipated increase in container import volumes.  The reanalysis effort was conducted to account for this significant increase in waterborne commerce, as well as reductions in project costs since the time of the feasibility study.  DMA updated commodity forecasts, and fleet projections, reassessing landside throughput capacity, conducting a market share analysis, reevaluating future without project conditions, and computing project benefits and costs.
DMA has unmatched experience in conducting plan formulation, environmental and economic analyses of deep draft navigation projects throughout the nation, both for our Port clients and for the U.S. Army Corps of Engineers.  The purpose of DMA’s investigations is to determine the feasibility of major port improvement projects and to prepare the decision documents necessary to authorize and implement project construction.
 
The Federal interest in navigation is derived from the Commerce Clause of the Constitution and is limited to improvements in the navigable waters of the U.S. which are of general public interest and open to use by all on equal terms.  Navigation improvements include:  channels, jetties and breakwaters, locks and dams, basins or water areas for vessel maneuvering, such as turning basins, anchorages, mooring areas, etc., removal of wrecks and obstructions, snagging and clearing, drift and debris removal, and bridge replacements or modifications (when necessary to remove obstructions to navigation).  Increasing these commercial navigation projects are also being pursued by non-Federal interests under authorities provided by Congress for them to do so.  DMA works for both Federal and non-Federal clients in the conducting the planning and leading the approval processes for these projects.

Economic Analyses for Navigation Improvements – Feasibility Study 

Norfolk Harbor (Craney Island), Virginia 

Norfolk District, US Army Corps of Engineers

DMA conducted an economic analysis of the benefits that would be associated with a new container terminal at Craney Island.  Without development of a new facility, the port is likely to reach throughput capacity in the next decade.  Expansion of Craney Island eastward would provide the opportunity to build a new container facility to meet this excess demand.  DMA is calculating the benefits associated with this new facility by identifying the differences in transportation costs between a new Craney Island facility and the most likely alternative transportation scenarios that shippers would have to employ if Craney Island was not available and traffic had to be diverted to alternative ports.  As a part of this investigation, DMA developed commodity projections, fleet forecasts, identifying alternative port options, and calculating both water-side and land-side transportation costs from point of origin to final destination.  DMA assisted the District during Corps Headquarters review, resulting in a positive Chief of Engineers Report and authorization by Congress.
