Noise mitigation measures for residences within 65-69 DNL.

The City of Chicago Department of Aviation received a $16.7 million Project Grant from the Federal Aviation Administration (FAA) under the Airport Improvement Program (CFDA 20.106) on September 22, 2025, to implement residential noise mitigation measures for properties affected by airport noise exposure. Phase 1 of this project, funded through this award, will acquire and install sound insulation systems in approximately 111 residences located within the 65-69 DNL (Day-Night Level) noise contour zone. The grant supports the broader objective of mitigating airport noise impacts on nearby communities while advancing the FAA's strategic goals of safety and operational excellence through infrastructure investment.

The project extends through September 21, 2029, and is part of a larger initiative addressing noise exposure at Chicago's airport system, which ultimately encompasses approximately 210 residences. Noise mitigation initiatives under the Airport Improvement Program represent a recognized eligible project category that supports long-term environmental protection and community benefit objectives consistent with the FAA's mandate to maintain a comprehensive national airport system adequate to meet civil aeronautics needs.
