Aircraft noise in Rancho Cucamonga is regulated by the FAA, not the city. Ontario International Airport, about 3 miles south, operates under an FAR Part 150 noise program.
Under federal preemption, local governments including Rancho Cucamonga cannot directly regulate aircraft in flight. Ontario International Airport (ONT) sits just south of the city and generates the majority of overflight activity, including FedEx and UPS cargo operations that run at night. The Ontario International Airport Authority operates under an FAA-approved FAR Part 150 Noise Compatibility Program that maps 65 dB CNEL contours and funds sound insulation for qualifying homes in affected areas. Portions of southwestern Rancho Cucamonga, especially neighborhoods south of Foothill Boulevard and west of Haven Avenue, fall under departure and arrival flight paths. Residents can file noise complaints with the ONT noise abatement office, which logs reports and coordinates voluntary nighttime preferential runway use with the FAA. Cable Airport in Upland is also nearby and contributes light general aviation noise. The city of Rancho Cucamonga advises residents to report persistent noise concerns to ONT directly at (909) 544-5360.
