R.A. Wiedemann & Associates was selected in association with the University of Illinois to perform an economic impact assessment for DuPage Airport. The Airport, with 470 based aircraft, is one of the largest general aviation facilities in the nation. Over the past 10 years, the DuPage Airport Authority has spent more than $204 million on airport improvements. This spending has positioned the airport to accommodate demand and adapt to changing conditions for the long term future. Of concern has been the emergence of taxpayer groups who point to the airport as a symbol of government overspending. Unknown to these groups has been the economic impact of spending, the real cost (revenues and taxes collected by the Authority that offset local expenditures), and the number of jobs produced and sustained by the airport. Our report documented these statistics and showed conservatively, that the airport produced an annual impact of over $200 million, with 2,000 jobs. A large survey of the airport’s users was taken and management initiatives were developed from the results.
