Centennial Airport is one of the busiest airports in the country, and while the airport contributes more than $1.39 billion in economic impact to the area, the Arapahoe County Public Airport Authority works diligently to balance the needs of the airport with those of the surrounding community.
When buying a new home, there are many things to be considered. Location is one of very high importance. Prospective home buyers should be informed consumers.
This guideline will help you ask the right questions to make informed choices about your new home: Noise Quest
Before you consider buying or renting a home near the airport, if you feel you may be sensitive to the noise, we encourage you to talk with your potential new neighbors and spend time near the property, during peak takeoff and landing times. If possible, visit the property at night (during the times you would most likely be sleeping) to better evaluate how the noise may affect you.
Keep in mind that many people who live in the area may not be as sensitive to noise as you, so it's important to experience it first-hand. Centennial Airport staff are happy to visit with you and show you detailed maps of flight patterns that can help you make a more informed decision. The same goes for those individuals considering purchasing property for investment. Remember to consider what types of tenants to whom you are looking to rent.
Centennial Airport has a variety of noise monitoring systems and tools, and can also run statistics on overflights to help guide your decision to reside near the airport.
The FAR Part 150 Study is a formal evaluation of aircraft noise and land use compatibility authorized under the U.S. Code of Federal Regulations (14CFR) Part 150, titled "Airport Noise Compatibility Planning." It is a voluntary Federal Aviation Administration (FAA) program in which Centennial Airport has participated in the past, completing an original study in 1998, with subsequent amendments. The current Part 150 Study and subsequent updates present aircraft noise based on current conditions and forecast aircraft activity in five years.
In 1997, a grant application was submitted to the Federal Aviation administration (FAA). Barbard Dunkelberg & Company was selected in September of 1998 to conduct the study.
As a result of that study, two committees were formed, one representing the technical aspect of the study (Technical Advisory Committee, TAC) and the other representing the communities (Community Advisory Committee, CAC) around the airport. The consultant worked with the committees to develop and prioritize the following 12 recommendations:
1. Ban Stage 1 aircraft
2. Ban Stage 2 jet aircraft under 75,000 lbs. at night
3. Implement-010 degree departure heading for business jets at night
4. Test 24-hours of Flight Tracks between 350 and 010 degree headings
5. Eliminate preferential runway use procedure
6. Implement 170 degree departure to 4 DME or 8,000 MSL (+/- 20 degrees)
7. Amend community plans and zoning ordinances
8. Update and establish environmental/noise abatement liaison/office
9. Install noise monitoring system and develop program
10. Development/implementation of Fly Quiet Program
11. Operations review and Part 150 Updates
12. Establish follow-up roundtable/committee.
The consulting firm also developed existing and future noise exposure maps (NEMs) based on the recommendations and forecasts. These are the noise contour maps that define the National DNL 65 threshold noise standard as well as lower and higher noise contours.
On October 11th, a Public hearing, proceeded by an open house, was held to provide all interested parties with an opportunity to voice their ideas/concerns. Then on November 15th the Airport Authority Board approved the Committee's recommendations in order to formally submit the recommendations to the FAA. The next step is for the FAA to place the recommendations on the docket and acceptance of the NEMs begins the 180-day FAA review process. The FAA can then either approve, disapprove or approves as a voluntary measure only, the recommended alternatives of the noise compatibility program. The final step in the formal Part 150 process is for the Airport to begin implementation of the airport noise mitigation program.
So you can see we've come a long way, but still have some work ahead of us. For more information on the Part 150 at Centennial, contact Aaron Repp, Noise Specialist at 303-790-0598, ext. 2922.
