From the FAA:

The Federal Aviation Administration (FAA) has released the Final Environmental Assessment for the proposed Denver Metroplex Project for public review. The Denver Metroplex project would improve the efficiency of the national airspace system in the Denver region by optimizing aircraft arrival and departure procedures at Denver International Airport and four outlying satellite airports. A 32 day comment period from November 18, 2019 through December 20, 2019 is available where the interested public can submit comments on the Final Environmental Assessment. The purpose of the comment period is to provide an opportunity for the public to review the changes from the Draft Environmental Assessment to the Final Environmental Assessment, as well as comment related to Section 106 of the National Historic Preservation Act. The FAA will review and consider each comment prior to making its decision whether to implement the proposed Denver Metroplex Project. 


In 2017 the Federal Aviation Administration (FAA) held informational workshops to distribute information on the proposed airspace improvements for the Denver metro area. The FAA hopes redesigning the airspace will address inefficiencies that impact several airports in Colorado including DIA and Centennial Airport which cost over $1.8 million in fuel annually. 

The Denver Metroplex redesign may involve changes in aircraft flight paths and altitudes in certain areas. The City of Cherry Hills Village is currently in the arrival and departure path for both DIA and Centennial Airport. These changes could substantially increase flight traffic over the Village, as much as a flight every few minutes.


The deadline to submit electronic comments to the FAA through their website was June 5, 2017. The Mayor and City Council are collaborating with other Denver Metro Area communities to oppose the implementation of Metroplex Denver until local communities receive adequate information to assess the impact of Metroplex as applicable to their specific community and have the opportunity to submit documentation to the FAA with respect to noise sensitive areas in their communities, consistent with applicable law.
