  • Progress on Noise Monitor Installation

    October 3, 2017

    The Chicago Department of Aviation (CDA) announced that it has secured permits and scheduled contractors to install permanent aircraft noise monitors at three suburban locations. Electrical installation and concrete work will begin on October 9, 2017 in Bensenville (Site 31), Itasca (Site 44) and Norridge (Site 18) with monitor installations to follow.

    A CDA spokesperson told the O’Hare Noise Compatibility Commission (ONCC) Technical Committee that once the city completed the monitor installation, Commonwealth Edison would activate the power source within a few weeks.

    Mayor Rahm Emanuel ordered eight new monitors for the Airport Noise Management System (ANMS) within the O’Hare region to capture aircraft noise in 2014 after residents began complaining about new flight patterns over their houses.

    There are five additional noise monitors scheduled for Chicago that are currently under review in the installation program. Site 42 located in Chicago was completed in June 2015.

  • CDA Briefs Technical Committee on Fly Quiet Rotation Plan

    April 19, 2016

    The Chicago Department of Aviation briefed the ONCC Technical Committee on a six-month Fly Quiet Rotation Plan test during the April 19 meeting. The nighttime rotation plan, calls for 12 one-week periods that incorporate parallel and diagonal runways and six east flow and six west flow configurations.

    Before the presentation, ONCC Chair and Mount Prospect Mayor Arlene A. Juracek reminded the members that it was “important to do our homework” and engage in dialog, analyze the viewpoints and take a “regional approach” to mitigate aircraft noise.

    The Commission is looking for a two thirds majority vote to change the status quo and pass the Fly Quiet rotation plan at its May 6 meeting. Once passed, the plan can be submitted with the “confidence of community consensus” to the Federal Aviation Administration for implementation by June or July.
