CMT led the Environmental Impact Statement for O’Hare’s $7.5B modernization program. Some of the major elements of the project included the realignment, addition and extension of six runways; three new terminal buildings, including an O’Hare Western Terminal concourse and access; acquisition of more than 440 acres of industrial/residential areas; major railroad/public road realignments; and the development of over 3,000 acre-feet of stormwater detention facilities. Partnering with the FAA, CMT streamlined the review process, setting a new national standard for major EIS completion.
