Public meeting set on John Glenn Columbus International Airport (KCMH) noise study

A virtual meeting will be held online Wednesday to present for public comment the latest updated study information on aircraft noise levels in areas around John Glenn Columbus International Airport.

The Columbus Regional Airport Authority has for months been updating the airport’s Part 150 Noise Compatibility Study — a voluntary noise abatement program established through the Federal Aviation Administration and named for the part of the 1979 federal act that established it.

The study involves updating noise contour maps around the airport to identify where the average day-night sound levels from aircraft operations are measured at 65 decibels or above, which is considered incompatible for houses, nursing homes, hospitals, schools, churches and other noise-sensitive uses.

John Glenn airport’s two parallel runways operate about 77% of the year with takeoffs to the west and landings from the east. Wind and weather conditions the other times of the year reverse that.

Noise readings are collected from 16 permanent monitoring sites around the airport as well as 30 temporary sites added for the study. The airport authority’s goal is to reduce or mitigate aircraft noise levels over homes and other noise-sensitive land uses where possible. That can include evaluating air traffic control procedures to reduce excessive noise over residential areas.

The authority also uses the noise contour maps developed from the study to work with local and county planning and development agencies to try and limit noise-sensitive development in excessive noise areas.

The Part 150 Study for John Glenn airport — known to those in aviation by its three-letter FAA designation of CMH — was last updated in 2007. The future noise exposure levels in that study were for 2012 conditions.

The authority has held previous public meetings to collect citizen comment on the updated study. The meeting Wednesday is a final chance for the public to comment on the latest study for consideration before the plan is sent to the FAA.

The virtual public meeting will be held online from 5 p.m. to 7 p.m. Wednesday, when the draft study findings and maps to date will be presented.
