Martin Associates

March 2019

As a service to the American Association of Port Authorities (AAPA), Martin Associates has prepared this National Economic Impact Study of the U.S. Coastal Port System. To determine the impact, Martin Associates used a combination of its own 64 individual seaport impact models that have been developed in the last three years along with prototype models developed from these 64 seaport-specific models. The seaport models include ports on the West Coast, Atlantic Coast, Gulf Coast, and the Great Lakes.
