6. JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT - QUARTER THREE AND QUARTER FOUR, 2025 This agenda report transmits the John Wayne Airport Noise Abatement Quarterly Report covering the third and fourth quarters of 2025. The City of Tustin is within the John Wayne Airport’s “Noise Impact Area” since it has the potential to experience an average Community Noise Equivalent Level above 65 decibels. Community Noise Equivalent Level is a weighted 24-hour average of noise levels, a measurement often used to regulate airport noise impacts on the surrounding community. The average noise levels measured at Tustin’s monitoring station, located at Columbus Tustin Middle School on Beneta Way (site map in Attachment A), remained below City, County, and State maximum criteria in the first and second quarter reporting periods. Recommendation: Recommend the City Council receive and file the report. Fiscal Impact: There is no fiscal impact associated with this item.
