SCHINDLER, CITY MANAGER FROM: ALEXA SMITTLE, DIRECTOR OF COMMUNITY DEVELOPMENT SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT — QUARTER ONE AND QUARTER TWO, 2025 SUMMARY: This agenda report transmits the John Wayne Airport Noise Abatement Quarterly Report covering the first and second 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.

Although engines generate much of the noise, other factors influence noise perception, including: proximity; weather - engine noise reflects off the atmosphere in bad weather, making jets seem louder than on clear days; routes - non-scheduled operations such as military or private aircraft may exceed commercial aircraft noise; emergencies; and weight - a heavier load can affect an aircraft's rate of ascent. Higher noise levels have also been noted in recent reporting periods as regional air travel has returned to pre -pandemic levels. During the first and second quarters of 2025, the average Community Noise Impact Level (CNEL) at Tustin's monitoring station on Beneta Way measured 57.8 decibels (dB), compared with 57.1 dB from the previous two quarters (third and fourth quarters of 2024). Figures 1 and 2 show Tustin's CNEL levels for each month of the first and second quarters of 2025.

The ANO receives and investigates noise complaints from local citizens and other sources. In the first quarter of 2025, 42 Tustin -area concerns were submitted; the second quarter also recorded 42 concerns. All complaints came through the noise hotline or the JWA mobile app alert button. JWA staff reported that in the first quarter, two (2) individuals submitted concerns, with one (1) person responsible for 41 of the 42 submissions. In the second quarter, one (1) individual submitted all 42 concerns through the app. Staff reviewed noise levels at Tustin's monitoring station during these periods and found no unusual increases in measured levels. Since the release of the noise reporting mobile app and web -based platform (second quarter of 2022), the trend has continued: a small number of individuals submit multiple complaints by pressing the app's alert button. Before the app and web platform, complainants typically called JWA, and data showed an average of one concern per quarter. To show the trend in Tustin -area complaints over the past three years, Figure 3 displays the number of noise complaints quarter by quarter.

Noise Standards Submitted by: E Signed by: A1A526A921AF49F... Charlene V. Reynolds Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 209th 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-1 S: 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 (April 1, 2024 - March 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 VWX 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 (January 1, 2025 - March 31, 2025) The Airport's Access and Noise Office receives and investigates noise complaints (noise events) from local citizens and all other sources.

Mr. Kyle Gorny, ANO Specialist, provided an overview of the Airport's Q4 2024 quarterly noise report ("QNR"). Mr. Nikolas Gaskins, ANO Manager, presented updates on the Airport's Plan Year 2025 Million Annual Passenger (MAP) projection, supplemental allocation of Class E Seat Capacity, and an update on the status of the 2024 Fly Friendly Program tier winners announcement and annual report. Newport Beach resident, Dr. Jim Mosher, commented on the long term measured aircraft noise level values located on the Airport's website, stating it did not reflect 2024 data. In addition, Dr. Mosher mentioned he could not locate the 2024 annual contour on the website. Mr. Gaskins explained that the annual contour and the 2024 long term measured aircraft noise level values would be updated on the webpage within the next day. Dr. Mosher mentioned he had recently attended a JWA Airport Land Use Commission (ALUC) meeting. Dr. Mosher had questions regarding the contour used in the Airport Environs Land Use Plan ("AELUP") and mentioned that there appeared to be discrepancies between that contour and the contour presented in the recent QNR. Dr. Mosher explained that the contour in the AELUP shows areas of enhanced noise where propellor aircraft overfly when utilizing the traffic pattern, whereas the contour in the QNR did not represent that enhancement. Mr. Gaskins stated he would discuss with the Airport's acoustical engineering consultant, as well as Ms. Julie Fitch, JWA's Planning Manager, who oversees ALUC. Dr. Mosher commented on the Airport's "Facts at a Glance" webpage which had previously compared 2023 and 2022 operational data. Dr. Mosher mentioned that the data needed to be updated to show 2024 statistics. Mr. Gaskins informed Dr. Mosher that the information had been updated to reflect the 2024 and 2023 comparison data, and directed Dr. Mosher to visit the webpage once more to confirm. Dr. Mosher asked if JSX's regularly scheduled flights and on -demand flights count towards the Airport's MAP. Mr. Gaskins explained that the regularly scheduled flights do count towards the MAP being JSX is a Qualified Commuter Air Carrier at JWA. Mr. Gaskins noted, that to the Airport's knowledge, JSX is not operating any on -demand service separate from their scheduled service. Mr. Gaskins went on to explain that the Airport has seen a decrease in load factor percentages due to several contributors. Mr. Gaskins explained that some of these contributors included aircraft manufacturer delays in deliveries, recently imposed tariffs, and the recent wildfires in Southern California. Mr. Gaskins continued to share that the current MAP projection is 11.1. Mr. Gaskins further explained that the Airport was in the process of reallocating up to 245,000 supplemental seats for the remainder of the 2025 Plan Year. Mr. Gaskins did note that while the Airport is providing this supplemental allocation, there is no guarantee that the carriers will utilize all of it. Mr. Gaskins provided a 2024 Fly Friendly Program (FFP) update, informing attendees that the FFP tier winners would be recognized at an upcoming Board of Supervisors meeting sometime in April. Mr. Gaskins highlighted that there has been some positive growth when it comes to the FFP annual results, particularly in the nighttime noise reduction category, when compared to Years 1 and 2 of the program. Mr. Gaskins stated that the Airport was awaiting confirmation from the Newport Beach Aviation Committee on when the altitude and noise analysis would be presented. Mr. Gaskins mentioned that it may occur at the April 21, 2025, meeting. Dr. Mosher asked if JSX's passengers will be counted toward the MAP now that JSX is operating out of Jay's Air Center. Mr. Gaskins reassured Dr. Mosher that JSX is still required to adhere to the Access Plan regulations, regardless of operations location. Dr. Mosher commented that JSX's office and passenger reception area resulted from a "through the fence" agreement, and asked if that was consistent with the Access Plan. Mr. Gaskins explained that he did not have those details but that question could be addressed at an upcoming Airport Commission meeting. Dr. Mosher commented that the Fly Friendly Program's scoring report is not downloadable, specifically into an Excel spreadsheet, and asked if the Airport would contact BridgeNet International ("BridgeNet") and request that the feature be implemented. Mr. Gaskins informed Dr. Mosher that he would contact the vendor about this feature to see what it would entail to implement. Dr. Mosher asked how aircraft, such as HDJT (N426DH) and CL30 (N22XZ), have almost perfect scores and the other operations with the same aircraft have lower scores. Dr. Mosher mentioned that both operators can be found in the non -participants tier of the FFP scoring report when sorted by quiet departure noise score. Dr. Mosher inquired why the CL30 did not receive a score in the quietest fleet score. Dr. Mosher also asked if BridgeNet is identifying all JSX operations. Mr. Gaskins responded that the FFP scoring report strictly monitors general aviation operations. Lastly, Mr. Gaskins shared that next -generation aircraft operations are increasing at JWA. Mr. Gaskins mentioned that a report highlighting this increase would be presented to Orange County Board of Supervisors, Vice Chair Katrina Foley, at an upcoming JWA Advisory Group meeting.

Noise Standards Submitted by: Signed by: A1A526A921AF49F... Charlene V. Keynoias Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 210th 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-1 S: 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 (July 1, 2024 - June 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".

Insufficient data is indicated by VWX 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).

Mr. Gaskins presented updates on the operation projections for 2025, noting a decrease in the first few months of the year and a possible projected decrease in August and September. Mr. Gaskins mentioned that Commuter Carrier operations increased most likely due to the relocation of JSX from ACI Jet to Jay's Air Center, which permitted an increase in JSX's passenger allocation from 95,070 to 130,000 passengers for 2025. Mr. Kyle Gorny, ANO Specialist, then provided an overview of the Airport's Q1 2025 quarterly noise report ("QNR"). Mr. Gaskins provided an update on the Plan Year 2026 capacity allocation process, reminding attendees that the Airport will confirm in February 2026 whether it meets the Environmental Impact Report ("EIR") 617 mitigation measure, LU-2. Mr. Gaskins explained that if the Airport meets the requirements, the Airport anticipates an increase from 11.8 to 12.5 million annual passengers ("MAP"). Mr. Gaskins informed attendees that all 2024 Fly Friendly Program data had been compiled, and the tier winners announcement was made in May 2025 during a special recognition event at Clay Lacy. Mr. Gaskins went on to explain that extensive outreach has been conducted, and the Airport is beginning to see positive changes. Mr. Gaskins did reiterate, however, it will take time for operators to become fully aware of the program and its elements. Mr. Gaskins shared that the Airport has been involved in researching the concerns of Central Park West residents in Irvine. Mr. Gaskins mentioned that the Airport is actively working with JWA flight schools on possible solutions. While the Airport is thoroughly investigating the matter, Mr. Gaskins stated that certain actions fall outside the authority of the County of Orange, and are instead, under the jurisdiction of the Federal Aviation Administration ("FAA"). Newport Beach resident, Ms. Seti Lee, inquired about potential solutions to current noise concerns, noting that the level of noise experienced had not been anticipated. Ms. Lee referenced a sound insulation program that was implemented several years ago. Mr. Gaskins responded that a program had existed approximately 20 years ago, specifically for those homes within the 65 decibel ("dB") contour. However, Mr. Gaskins stated the program in no longer active. Mr. Gaskins mentioned that while some noise reductions may appear minimal, we are entering an era of transitioning to next -generation aircraft, which are designed to operate cleaner and more efficiently. Mr. Gaskins explained that as more of these aircraft are deployed at higher levels, it is hoped that they will contribute to a noticeable improvement in noise levels. Central Park West resident, Ms. Pattie Leslie, mentioned a conversation she had with a community member that is an Alaska Airlines pilot. Ms. Leslie stated that she was informed that some airlines may choose to operate flights despite curfew restrictions, and accept the associated penalties. Mr. Gaskins explained that the current settlement agreement, set to expire in December 2030, will be renegotiated with the settlement parties. Mr. Gaskins mentioned that discussions, such as adjusting the fine structure, may be addressed. Mr. Gaskins explained that the Airport is actively reviewing this issue. Ms. Leslie asked which community groups are part of the settlement agreement, and whether it would be worthwhile to explore joining one of them. Mr. Gaskins responded that Ms. Leslie is certainly welcome to research and join one of the groups, if able. Additionally, Mr. Gaskins explained that one group, Stop Polluting Our Newport ("SPON") may be more focused on issues surrounding Newport Beach, while the other group, Airport Working Group ("AWG") may represent more communities surrounding the Airport. Mr. Jack Stranberg, Newport Beach Aviation Committee Member, asked what million annual passenger ("MAP") Limitation the Airport is using for allocation of capacity in Plan Year 2026. Mr. Gaskins explained that while the MAP Limitation is set at 11.8, the Airport allocates approximately 11.5 to provide a buffer in the event load factors increase during the Plan Year. Mr. Gaskins further explained that if the MAP Limitation increases to 12.5 million in 2026 and trends indicate lower - than -expected usage, the Airport should be able to offer additional capacity to carriers. Dr. Jim Mosher, Newport Beach resident, expressed concern that the current noise contour discussed at a recent Airport Land Use Commission ("ALUC") meeting may not accurately reflect noise from smaller propellor aircraft, noting that the contours being used were originally produced in the 1980s. Mr. Gaskins responded that all aircraft noise is represented in the current contour. Mr. Gaskins stated that he will reach out to the ALUC Executive Officer, Ms. Julie Fitch, to discuss the matter further. Dr. Mosher also suggested implementing remote NMS to ensure more accurate data collection. Mr. Gaskins mentioned he could contact the Airport's noise monitoring system services vendor to discuss portable noise monitoring, but also emphasized that noise modeling is a preferred and reliable method of noise data collection by most airports throughout the country. Dr. Mosher inquired about the QNR, specifically referencing Table 2, which shows a sharp drop in readings across all monitors except NMS 6S. Mr. Gaskins explained that reverse flow operations tend to be more frequent from November through March, and any significant drop at NMS 6S could be attributed to arrival operations and ongoing construction at the NMS location. Dr. Mosher suggested that it would be helpful to separate the number of operations, as the counts in the report do not appear to align with data from each NMS. Mr. Gaskins responded that the thresholds set at each NMS determine noise event collection, which explains why, at times, more readings may be recorded at NMS 1S, 2S, and 3S, while a decline is observed at the remaining NMS locations. Mr. Gaskins asked Dr. Mosher to send an email with further details for follow-up. Dr. Mosher asked about the progress of the Airport's noise and operations data portal. Mr. Gaskins advised that the Airport is currently researching several approaches to how the data portal will be built and displayed. Mr. Gaskins added that the Airport still has the public -facing Detailed Noise Events Report available on the Airport's website. Dr. Mosher asked about a previous question asked at the last quarterly noise meeting regarding the Fly Friendly Program scoring of a Challenger 300 and HondaJet aircraft. Mr. Gaskins advised that BridgeNet is still researching the matter.
