4. JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT
This agenda report transmits the John Wayne Airport (JWA) Noise Abatement Quarterly Report for the third and fourth quarters of 2022. The average noise level measured at Tustin’s monitoring station (NMS 10N), located at Columbus Tustin Middle School on Beneta Way (Figure 1), remained consistent with prior quarters. Average daily noise levels during the third and fourth quarters continued to remain well below the City, County, and State criteria of 65 decibels (dB) Community Noise Equivalent Level (CNEL) for residential uses. Residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area."
