O’Hare International Airport – A Flight Path to Sustainability By Dorothy Izewski // Chicago Department of Aviation (CDA)
Rating Program. Based on the concepts of LEED, this new program applied to civil engineering and landscaping projects, rewarding compliance with green airplane certificates.
hicago O’Hare International Airport is currently the second busiest airport in the world. For an airport that has been operating commercially since 1955, keeping up with industry growth and new aircraft development is a necessity but sustainability is a choice.
THE NORTH AIR TRAFFIC CONTROL TOWER IS THE FIRST LEED CERTIFIED AIR TRAFFIC CONTROL TOWER, AND APPROXIMATELY EIGHT ACRES OF GREEN ROOFS HAVE BEEN BUILT AT O’HARE.
To stay competitive in the changing aviation industry, the dated runway system at O’Hare needed to be modernized so the City of Chicago announced the O’Hare Modernization Program (OMP) in 2001. The OMP’s commitment to green construction practices led to the development of a Sustainable Design Manual (SDM) and Green Airplane
This program resulted in an innovative balanced earthwork plan, which eliminated the need to remove material off-site. Cut and fill is carefully calculated and movement is minimized, reducing energy, emissions and cost. Recycled concrete, crushed on-site, is used as aggregate for

new concrete pours. The North Air Traffic Control Tower is the first LEED certified air traffic control tower, and approximately eight acres of green roofs have been built at O’Hare. Implementing change is difficult, especially when there are regulatory and cultural challenges. An airport environment is governed by safety and security. The Sustainable Landscape Specifications used at O’Hare are based in part on the Federal Aviation Administration (FAA) Advisory Circular, “Wildlife Hazard Management at Airports,” to minimize wildlife hazards, particularly birds and small mammals. Landscape that provides food or shelter to these animals must be avoided. This is in sharp contrast to what is promoted in the landscaping industry, where wildlife attractants are highly desirable. A very limited list of approved plants is provided by the [continued on page 14]
