In an effort to respond to the public requesting data related to the draft OHare Modernization Environmental Impact Statement (EIS), the Federal Aviation Administration (FAA) is making technical data available much earlier in the EIS process. This website is being used to make that data available to the public.
In support of the planning and environmental analyses of O;Hare Modernization, FAA is using computer simulation modeling. The computer modeling includes Delay and Travel Time Analysis, Noise Analysis, Air Quality Analysis, and Surface Transportation Analysis.
As this data becomes available in draft final form, FAA will post the various components of each analysis including the assumptions, project files, and supporting material used in the modeling efforts. However, please be advised that this data continues to be reviewed by FAA and may change.
The below directories will contain the draft final modeling data for the following analyses:
