Final Environmental Assessment for the Proposed Runway Safety Extension Project is Now Available
Consistent with the requirements of the National Environmental Policy Act, the City initiated an environmental assessment (EA) process to determine the potential impacts of lengthening the primary runway at the Ann Arbor Municipal Airport. The EA addresses potential impacts to noise levels, air quality, water quality, wetlands, floodplains, plant and wildlife, light emissions, historical and cultural resources, traffic, social and socioeconomic factors. After multiple public hearings and opportunities for public input, the EA process has been completed and the results determined there would be no significant impacts if the proposed project moves forward.
The entire EA document is available for review by accessing the links below or visiting one of the public locations listed in the Notice of Availability of a Final Environmental Assessment (link below) to view a printed copy of the EA. Printed copies will be available for viewing until January 12, 2024. The scope of the proposed runway project, detailed in the EA document, would result in an increase of the primary runway length from 3,505' to 4,225'. No runway changes have been approved or scheduled to date.
The final EA is available online below. The full EA document is a large file (over 3,600 pages) so the document has been split into smaller files to make downloading easier.
