GEC’s Economics and Planning staff has provided consulting assistance to port and harbor authorities, terminal operators, shippers, and U.S. Army Corps of Engineers districts nationwide for over 30 years. GEC’s Navigation Economics staff has conducted investigations for ports in the Arctic, Pacific, Atlantic oceans, Gulf of Mexico, the Mississippi River, Ohio River, McClellan-Kerr Waterway, Gulf Intracoastal Waterway, and Atlantic Intracoastal Waterway.

The broad geographical experience of the staff is accompanied by a corresponding breadth in the areas analyzed. The staff is experienced with inland and maritime water transportation, deep and shallow draft harbors, and recreational and commercial facilities. It has completed feasibility analyses for recreational harbor expansions; deep draft fl eet
and commodity forecasts for U.S. Army Corps of Engineers districts; strategic and master planning analyses for port authorities; market demand estimates for private clients; and economic impact analyses for port authorities and waterway organizations.

GEC’s economists are experienced in the study procedures required to evaluate the economic feasibility and economic impact of navigation and ports improvements. The GEC staff economists include Dr. Kevin Horn, one of the nation’s foremost transportation economists. The GEC economics staff utilizes all current methods for the identi fication of potential water borne commerce, the latest computer software available for the evaluation of navigation feasibility and economic impacts such as the Maritime Administration’s Portkit Model, and econometric models such as the Department of Commerce’s RIMS-II Model and IMPLAN.
