What must an airport's noise mitigation program be based on to receive federal funding?

To receive federal funding for an airport's noise mitigation program, it is essential that the program is based on an FAA-approved Noise Exposure Map. This requirement ensures that the mitigation strategies are grounded in accurate and recognized data regarding the noise levels and their impact on the surrounding community.

An FAA-approved Noise Exposure Map is a critical tool that reflects the actual noise contour levels around an airport, allowing for an assessment of how much noise is affecting nearby populations. This map serves as a foundation for understanding the noise environment and identifying areas that may benefit from mitigation efforts.

By using an FAA-approved map, the program can target specific areas where noise reduction measures are most needed, ensuring that resources are allocated effectively. The federal funding process looks for systematic and scientifically-supported approaches, and the use of an FAA-approved document demonstrates compliance with federal regulations and guidelines designed to protect the community from airport noise.

This adherence to an FAA-approved map is crucial in ensuring that the noise mitigation program aligns with federal policies and ultimately secures necessary funding.
