SCHINDLER, CITY MANAGER Agenda Item 6 Reviewed: City Manager fits Finance Director N/A FROM: ALEXA SMITTLE, COMMUNITY DEVELOPMENT DIRECTOR SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT — QUARTER THREE AND QUARTER FOUR, 2025 SUMMARY: 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 this report. FISCAL IMPACT: There is no fiscal impact associated with this item. CORRELATION TO THE STRATEGIC PLAN: Staff's analysis and report of the quarterly John Wayne Airport Noise Abatement Report falls under Goal D of the Strategic Plan for strong community and regional relationships. The City of Tustin strives to work collaboratively with agencies within and outside Tustin on issues of mutual interest and concern and, in this instance, on airport traffic and noise. BACKGROUND AND DISCUSSION: At the conclusion of each calendar quarter, John Wayne Airport (JWA) noise office staff prepares a Noise Abatement Program Quarterly Report and posts it on their website. Their reports for the third and fourth quarters of 2025, covering July through December 2025, are included as Attachments B and C.

Although engines generate much of the noise, other factors influence noise perception, including proximity and weather. During the third and fourth quarters of 2025, the average Community Noise Equivalent Level (CNEL) at Tustin's monitoring station on Beneta Way measured 57.6 decibels (dB), effectively the same as the 57.8 level dB from the first and second quarters of 2025. Figures 1 and 2 below show Tustin's CNEL levels for each month of the third and fourth quarters of 2025.

Noise Standards Submitted by: ISigned by A1A526A92i AF49F... Charlene V. Reynolds Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 2111" Quarterly Report submitted by the County of Orange in accordance with the requirements of the California Airport Noise Standards (California Code of Regulations, Title 21: Public Works, Division 2.5, Division of Aeronautics (Department of Transportation), Chapter 6. Noise Standards). Effective January 1, 1986, the criteria for defining "Noise Impact Area" was changed from 70 dB to 65 dB Community Noise Equivalent Level (CNEL). Under this criteria, John Wayne Airport currently has a "Noise Impact Area." NOISE IMPACT SUMMARY Caltrans' Aeronautics Program has established guidelines in the California State Noise Standard to control residential area noise levels produced by aircraft operations using the State's airports. Under those guidelines, residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area." John Wayne Airport uses ten permanent remote noise monitoring stations (NMS) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS NMS-1S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-2S: 20162 S.W. Birch St., Newport Beach NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324'/2 Vista Madera, Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, Irvine NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS-10N: 17952 Beneta Way, Tustin The map in Figure 1 shows the general location of each permanent remote monitor station. Figure 2 shows the Airport's "Noise Impact Area" for the previous year (October 1, 2024 - September 30, 2025). The Figure 2 information was developed by Harris Miller Miller and Hanson Inc., in consultation with John Wayne Airport. CNEL values measured for the period and current digitized land use information were utilized to calculate the land area acreages, number of residences and estimated number of people within the "Noise Impact Area".

COMMUNITY NOISE EQUIVALENT LEVELS The monthly, quarterly, and twelve-month Community Noise Equivalent Level (CNEL) average values for each monitor station are shown in Table 2, while daily CNEL values are shown in Tables 3 through 5. Insufficient data is indicated by "#N/A" entries in each table. Also, "*#N/A" entries in each table indicate contaminated data and/or no aircraft -related noise events. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and General Aviation Jet aircraft are shown in Tables 6 through 8. ACOUSTICAL INSULATION PROGRAM Four hundred eighteen residences in the Santa Ana Heights area have been sound attenuated and an avigation easement reserved through the County's Acoustical Insulation Program, which closed in December 2009. The County has also acquired 46 residences as part of the Purchase Assurance Program, many of which were acoustically insulated, an avigation easement reserved and then resold. Among these County acquired homes, those located within areas designated for Business Park uses were razed, avigation easements were reserved, and the land resold for compatible Business Park uses. A total of 464 residences in the Santa Ana Heights area have been purchased or otherwise made compatible through the County's Purchase Assurance and Acoustical Insulation Programs. Seventy dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). COMPLAINT TOTALS (July 1, 2025 - September 30, 2025) The Airport's Access and Noise Office receives and investigates noise complaints (noise events) from local citizens and all other sources. Figures 3.1, 3.2, and 3.3 illustrate the distribution of reported noise events from local communities, the nature of disturbance, and the method of how the noise events were reported to the Airport. 4 - FIGURE 3.1 REPORTED NOISE EVENTS 99,316 Noise Events 184 Points of Contact July 1, 2025 to September 30, 2025 80.ODD 60,000 59,492 m W 26 N 0 Z `o 40,000 32,740 z0,Do0 1 10 7 5 40 30 28 ° I o 0 ° in 20 10 5 0 , 01 4. 0 1,189 1 ,713 447 303 2 284 72 56 1 �I Anaheim Newport Costa Laguna Huntington Laguna Irvine Other Silverado Beach Mesa Niguel Beach Beach NOTE: The 99,316 Noise Events was a 70.3% decrease for the 334,555 Noise Events from last quarter, and a 50.6% decrease from the 201,119 Noise Events from the same quarter last year.

A summary of the John Wayne Airport ("JWA") August 2025 airport statistics was provided by Mr. Anthony Cangey, ANO Specialist, highlighting a 9.2% year-to-year passenger increase. Ms. Cristina Fimbres, ANO Specialist, then provided an overview of the Quarterly Noise Report for the 2nd Quarter of 2025. Mr. Gaskins provided a Plan Year 2025 Plan Year Capacity update highlighting the projected 2025 million annual passengers ("MAP") of 11,253,134. In addition, Mr. Gaskins provided an updated timeline for the approval of the 2026 Plan Year Capacity Allocations by the Orange County Board of Supervisors. Lastly, Mr. Gaskins provided an update regarding the Environmental Impact Report mitigation measure LU-2, which determines if the Airport will increase to 12.5 MAP, effective January 1, 2026, if the Community Noise Equivalent Level ("CNEL") remains 1 dB or less when comparing the 2013 annual noise contour values to the 2025 annual noise contour values. Mr. Gaskins stated that the Airport is closely monitoring the progress and should have results sometime in February 2026. Irvine Resident Ms. Patti Leslie commented that the air traffic situation over her residence has recently improved. Mr. Gaskins responded that it could be due to the Airport's outreach to the Fixed Base Operators and flight schools, as well as certain weather conditions such as low ceilings and visibility. Ms. Leslie also commented that the Mayor of Irvine contacted her, and she told him that her community has seen an improvement. Ms. Cindy Yanez from the California Air Resources Board (CARB) stated she was attending the meeting because she was interested in learning about the Airport's access and noise program and how the Airport addresses emissions. Mr. Gaskins requested that Ms. Yanez send an email so the Airport could provide any additional information. In addition, another attendee, Mr. Mark McIntyre, requested general information on the Airport's access and noise program be sent to him. 16 - NAME Cindy Yanez Jim Mosher Patti Leslie Mark McIntyre Joe August Nikolas Gaskins Anthony Cangey Cristina Fimbres Cassandra Linares QUARTERLY NOISE MEETING ROSTER September 24, 2025 ORGANIZATION California Air Resources Board (GARB) Newport Beach Resident Irvine Resident (Central Park West) Unknown Newport Beach Resident John Wayne Airport John Wayne Airport John Wayne Airport John Wayne Airport SUMMARY OF STATISTICAL INFORMATION FOR CALIFORNIA DEPARTMENT OF TRANSPORTATION Size of Noise Impact Area as defined in the Noise Standards (California Code of Regulations, Title 21, chapter 2.5, Subchapter 6): 0.0100 Sq.

Noise Standards Submitted by: ESigned by: A1A526A921AF49F... Charlene V. Reynolds Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 2121h Quarterly Report submitted by the County of Orange in accordance with the requirements of the California Airport Noise Standards (California Code of Regulations, Title 21: Public Works, Division 2.5, Division of Aeronautics (Department of Transportation), Chapter 6. Noise Standards). Effective January 1, 1986, the criteria for defining "Noise Impact Area" was changed from 70 dB to 65 dB Community Noise Equivalent Level (CNEL). Under this criteria, John Wayne Airport currently has a "Noise Impact Area." NOISE IMPACT SUMMARY Caltrans' Aeronautics Program has established guidelines in the California State Noise Standard to control residential area noise levels produced by aircraft operations using the State's airports. Under those guidelines, residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area." John Wayne Airport uses ten permanent remote noise monitoring stations (NMS) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS NMS-1S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-2S: 20162 S.W. Birch St., Newport Beach NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324'/z Vista Madera, Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, Irvine NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS-1 ON: 17952 Beneta Way, Tustin The map in Figure 1 shows the general location of each permanent remote monitor station. Figure 2 shows the Airport's "Noise Impact Area" for the previous year (January 1, 2025 - December 31, 2025). The Figure 2 information was developed by Harris Miller Miller and Hanson Inc., in consultation with John Wayne Airport. CNEL values measured for the period and current digitized land use information were utilized to calculate the land area acreages, number of residences and estimated number of people within the "Noise Impact Area".

Insufficient data is indicated by "#N/A" entries in each table. Also, "*#N/A" entries in each table indicate contaminated data and/or no aircraft -related noise events. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and General Aviation Jet aircraft are shown in Tables 6 through 8. ACOUSTICAL INSULATION PROGRAM Four hundred eighteen residences in the Santa Ana Heights area have been sound attenuated and an avigation easement reserved through the County's Acoustical Insulation Program, which closed in December 2009. The County has also acquired 46 residences as part of the Purchase Assurance Program, many of which were acoustically insulated, an avigation easement reserved and then resold. Among these County acquired homes, those located within areas designated for Business Park uses were razed, avigation easements were reserved, and the land resold for compatible Business Park uses. A total of 464 residences in the Santa Ana Heights area have been purchased or otherwise made compatible through the County's Purchase Assurance and Acoustical Insulation Programs. Seventy dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour).

A summary of the John Wayne Airport (JWA) October 2025 airport statistics was provided by Mr. Anthony Cangey, ANO Specialist, highlighting an 8.4% year-to-year passenger increase. Mr. Cangey also provided an overview of the Quarterly Noise Report for the third quarter of 2025. Mr. Gaskins stated that the Orange County Board of Supervisors approved the Plan Year 2026 Capacity Allocations with an 11.8 MAP. Mr. Gaskins provided an update regarding the EIR 617 LU-2 Mitigation Measure, noting that the Airport is unlikely to meet the threshold required to increase the million annual passengers (MAP) limit to 12.5. Mr. Gaskins stated that the Airport will continue to make efforts to meet the threshold during the 2026 Plan Year, which could result in the increase occurring in the 2027 Plan Year. Mr. Gaskins also shared that he, the Airport Director, and the Assistant Airport Director have been meeting with the airlines to discuss topics related to air service development, such as fleet mix, performance measures, and potential market updates. Lastly, Mr. Gaskins shared that two additional features will be available on the Fly Friendly Program (FFP) scoring dashboard, which is located on the FFP webpage, and are expected to be launched within the next couple of weeks. Dr. Jim Mosher, Newport Beach resident, commented that there was a change in the land use parcel designation for Figure 2 in the 3Q25 report. Dr. Mosher mentioned that 20052 Birch Street, in Newport Beach, a previously residential property, will be demolished and turned into a Fletcher Jones car wash. Mr. Gaskins notified Dr. Mosher that he would provide this information to the JWA Land Use Planning Manager. Dr. Mosher stated he does not believe the Million Annual Passengers (MAP) increase referenced earlier will go directly to 12.5 MAP based on compliant annual noise contour values, but rather, the increase will be based on what is within 1 dB or less. Mr. Gaskins stated he would inform Airport staff to ensure messaging remains consistent. 16 - QUARTERLY NOISE MEETING Dr. Mosher asked why Southwest Airlines' Boeing MAX8 operations decreased after a higher count in August and September. Mr. Gaskins explained that the Airport was aware and had publicly stated that Southwest could incorporate a high number of Boeing MAX8 operations at JWA based on network planning schedules for those months. Mr. Gaskins also explained that while it is not regularly scheduled at those counts, the Airport was appreciative and understands some of the challenges carriers have in bringing in these newer aircraft - seat count, runway length, noise monitor locations, etc. Dr. Mosher stated that within the Fly Friendly reports, he thought he saw a new feature that was briefly launched on the website, then taken down. Mr. Gaskins explained that the latest feature may have been briefly launched and was likely removed when the Airport decided to review formatting consistency across all reports on the dashboard. Dr. Mosher asked if the Fly Friendly dashboard could be downloaded by the public. Mr. Gaskins stated that the ability to download the information has been brought up to JWA Executive Management and may be considered in future years. Mr. Joe August, a Newport Beach resident, asked about the status of the "missing" noise events from flight matching and mentioned that this has been a request since Metroplex implementation. Mr. Gaskins informed him that this item is on Supervisor Foley's JWA Advisory Group agenda, listed as "on the horizon." Mr. Gaskins explained that the Airport is currently managing the Access Plan amendments, capacity allocations, and upcoming settlement negotiations.
