Economic Impact & Feasibility Studies

The construction and operation of public infrastructure projects and large private development projects generates economic activity throughout local and regional economies. Measuring these impacts, in terms of increased business sales, personal earnings, and jobs allows supporters and developers of these projects to demonstrate the economic impact and importance of the project to constituents, the general public, and various other stakeholders.

GEC’s staff of economists and planners has broad experience in estimating the economic impact of proposed or existing projects on local and regional economies. This experience includes estimating local and regional impacts of large public works projects, such as waterway projects utilized for both commercial and recreational uses, and industrial, commercial, and institutional projects.

The staff is experienced in the use of economic databases and economic impact models such as IMPLAN, RIMS-II, PORTKIT, and others.
