Residents living near O’Hare Airport have been voicing more noise complaints since late 2013 when runway changes went into effect. To the solve the problem, two sides in the debate have a similar idea: Send in the engineers. In the city’s corner, we have Ginger Evans, the recently appointed head of Chicago’s aviation department, a civil engineer by training. She was in charge of aviation and airport construction at Denver International Airport and was the second-in-command at Reagan and Dulles for a time. Ten days ago, she submitted some ideas about how to mitigate the noise. In the other corner, armed with power-points and color-coded infographics, a group of engineering consultants hired by the Suburban O’Hare Commission, one of the groups representing suburbanites in the towns and villages near O’Hare. Arlene Juracek gives us the lowdown on how all sides are working to fix the noise problem. She’s the mayor of Mount Prospect and she’s a trained mechanical and aerospace engineer. (Flickr/Piper)
